    The invention relates to a mounting pit according to the preamble of claim 1, a mounting device with such a mounting pit and a tank for liquid dangerous goods and the use of a cavity in a double-walled side wall of such a mounting pit for the storage of liquid dangerous goods in a tank.
    Installation pits are used by workshops or manufacturing plants for assembly, repair or maintenance of motor vehicles, rail vehicles, machinery or machine parts. The staff can work in a comfortable upright position under the appropriate vehicles and machines.
    Conventional assembly pits are usually made on site. For this purpose, first outer and inner shuttering walls are placed, which are then filled with filling material, preferably with concrete. The setting up of these formwork or the production of conventional assembly pits may require long employment of a variety of partially different craftsmen on site, so high production costs incurred and long construction times occur. In addition, manufacturers prefabricated assembly pits, so-called prefabricated assembly pits, known with steel cassettes, which are used in a Bodenausnehmung on site. Usually prefabricated assembly pits are made with sidewalls having an inner wall and a spaced outer wall with an intermediate cavity filled with a hardenable filling material such as concrete.
    For reasons of environmental protection, it is increasingly necessary in workshops to ensure proper storage and disposal of liquid hazardous goods, such as waste oil. For example, in assembly pits, oil from engines, transmissions, hydraulic devices, compressors, machinery, and other industrial oils and lubricants are waste. In particular, in commercial vehicles such as buses or trucks an oil change is practically possible only with the help of a mounting pit from the vehicle underside, the vehicle is driven over the mounting pit and the waste oil is discharged into a collection or collection container, which is emptied from time to time. Due to the fire protection regulations, a suitable storage space for waste oil, in particular a tank designed for this purpose, must be available in workshops, which in particular must meet the requirements of certain fire resistance classes. Such tank systems often require expensive buried underground lines and must be monitored.
    From EP 2 728 090 A1 a mounting pit for vehicles with a steel cassette is known, whose side walls have an inner wall and an outer wall arranged at a distance therefrom, which delimit a cavity filled with hardenable filling material. The cassette has a separate collecting space for receiving a collecting container for liquid dangerous goods. The separated collecting space is either, separated by a partition, in the interior of the cassette or as a lateral extension of the cassette, outside of a longitudinal or end wall adjacent, provided. Such a collecting space for a mounting pit has a lot of space. The available working space in the mounting pit is smaller by the collecting space or the establishment of a mounting pit by a lateral extension consuming, for example, due to the necessary adapted thereto and larger Bodenausnehmung or necessary manufacturing or adaptation work on site.
    Based on this prior art, the present invention seeks to provide a mounting pit with a storage space for liquid dangerous goods, which has a smaller footprint. In particular, the available work space should not be reduced by the storage room and a mounting pit to be set up quickly and easily. In addition, a mounting pit with a storage room for liquid dangerous goods should be safe to operate and in particular meet the safety requirements.
    This object is achieved by a mounting pit according to claim 1.
    In particular, the object is achieved by a mounting pit, in particular precast mounting pit, comprising a replaceable in a Bodenausnehmung mono- or multi-part pit body, in particular made of steel, which has a surrounding a pit interior side wall, a pit floor and a pit opening, characterized in that - a storage space for receiving a tank for liquid dangerous goods, in particular an oil tank, is provided in the pit interior below an entry or exit aid leading from the pit opening into the pit interior; and / or - at least one storage space for receiving a tank for liquid dangerous goods, in particular an oil tank, is integrated in the side wall.
    In particular, the pit body defines a pit interior which is accessible through a group opening formed on an upper side, in particular via an entry or exit aid, wherein a side wall extends in height in particular to the region of the pit opening. In particular, the side wall extends around the pit interior, wherein a pit body can be composed of a plurality of mutually firmly connectable pit modules. In particular, the pit body has a cuboid basic shape, in particular a substantially cuboid envelope, preferably without lateral extensions, in particular spacers, outwards.
    The pit body, and in particular the side wall, is preferably made of steel, but may also be made of a similar stiff and in particular corrosion-resistant material. The inventive mounting pit is used in particular for installation, repair or maintenance of vehicles.
    Under a liquid dangerous goods such liquids can be understood that are water polluting, flammable, explosive or somehow hazardous to health or the environment, especially waste oil, fresh oil or fuels such as gasoline, kerosene or diesel. In particular, regulations regarding labor, fire, explosion and / or environmental protection apply to the storage and handling of liquid hazardous goods.
    A first aspect of the invention is to arrange a storage room in the pit interior below an entry or exit aid. A second, independent aspect of the invention is to integrate at least one storage space in the side wall of the pit body. Both ideas can also be implemented simultaneously by providing a first storage space in the pit interior below an entry and exit aid and at least a second storage space is integrated into the side wall of the pit body. A demanding storage space may be contiguous for receiving a plurality of tanks. However, it can also be provided several, in particular separate storage rooms for receiving different tanks.
    With regard to the first aspect of the invention, the entry or exit aid is in particular a staircase or ladder and preferably extends from the pit opening obliquely downwards, in particular on a front side of the mounting pit. In particular, a storage space below an entry or exit aid is wider down and is preferably triangular or wedge-shaped in cross section. Such a storage space has the advantage that the typically unused space underneath an entry and exit help space-saving for receiving a tank for liquid dangerous goods is used. An entry or exit help is used in particular to allow a mechanic to enter or exit the work in the mounting pit.
    With regard to the second aspect of the invention, an integration according to the invention, the arrangement within the side wall, in particular a double-walled portion of the side wall, in particular between a side wall forming the outer and inner walls are understood. In particular, the side wall is at least partially double-walled, wherein the outer and inner walls are each formed in a single wall. A storage space is integrated into the side wall, in particular on an end face and / or a longitudinal side, wherein an arrangement over the corner is also conceivable, in particular if a tank received by the storage space is arranged in a cuboid along the front side or the longitudinal side. A side wall can be widened locally in an area in which a storage space according to the invention is integrated, in particular on one end side of the pit body, but preferably without locally widening the pit body to the outside, in particular without the outside wall projecting outwards. The distance between the inner wall and the outer wall can be increased in the area of the storage room.
    A mounting pit with a storage space according to the invention has the advantage that a tank for liquid dangerous goods can be installed to save space. On the one hand, this increases the space available for working within the assembly pit, on the other hand, a mounting pit, especially prefabricated assembly pit, easier to transport, especially because no lateral extensions of the pit body are necessary, which in particular facilitates a road transport to the installation site. In addition, a storage room for a tank can already be prepared in the factory. In particular, the storage room is already set up by the manufacturer in the assembly pit, whereby a tank can already be used or installed by the manufacturer or can only be used or installed and connected on site when the installation pit is installed. This can reduce the installation time of the mounting pit on site.
    In an advantageous development of the second aspect of the invention, the side wall is at least partially double-walled with an inner wall and a spaced-apart outer wall, wherein the storage space between the inner wall and the outer wall is integrated. In particular, a tank for liquid dangerous goods is integrated in a double-walled section of a side wall. The side wall is in particular at least partially double-walled, wherein the side wall in particular comprises a plurality of double-walled sections and is preferably continuous or substantially continuous, preferably along the longitudinal sides and end faces, double-walled. The side wall may also comprise several non-contiguous double-walled sections. Also, the bottom of the pit body may be double-walled. In areas where no storage space according to the invention is provided, cavities in the side wall and the floor may be interconnected.
    In particular, a plurality of wall elements are connected to one another such that they form the side wall at least partially double-walled. The wall elements are preferably made of steel, but may also be made of a similar stiff and in particular corrosion-resistant material. The wall elements are preferably welded together, but can also be releasably connected to each other. Preferably, the wall elements are single-walled, preferably prefabricated in one piece, in particular as one-piece parts. The wall elements can be angled as angle profiles with two legs with the same or different leg lengths, in particular as L-profiles, be formed. In particular, one leg forms an intermediate wall and the other leg preferably forms part of the inner or outer wall of the side wall. Preferably, legs are angled at right angles to each other. Angled wall elements have the advantage that they are simple and inexpensive to produce, in particular by forming, in particular bending, of originally flat wall elements, in particular steel sheets.
    A portion of the side wall is so far formed double-walled, as an inner wall to the pit interior and includes a spaced-apart outer wall to the environment of the pit body. The inner and outer walls are particularly single-walled, preferably as a sheet, e.g. with a wall thickness of 1 to 10 mm, preferably from 2 to 6 mm, particularly preferably from about 3 to 5 mm formed. In particular, located between the inner wall and the outer wall, a cavity in which the inventive storage space is provided, or which forms the storage space or limited. In particular, the storage space is arranged within the substantially cuboid envelope of the pit body, in particular within a rectangular outline of the pit body bounded by the outer wall. Unlike in the prior art, this cavity is not, at least not in the region of a provided for the inventive integration of the storage space portion of the side wall, with a, in particular curable, filling material, such. Concrete, filled, but remains hollow or empty, so that a tank for liquid dangerous goods can be installed or used. In particular, a cavity usually present in a double-walled side wall is used according to the invention as a storage space.
    An integrated between the inner and the outer wall storage space has the advantage that the already existing space within a side wall for storage of a liquid hazardous material is space-saving exploitable. For example, can be dispensed with the installation of a tank in the pit interior or outside the assembly pit.
    In an advantageous development of the second aspect of the invention, the storage space is formed in the form of a tight, in particular hermetic, closable wall chamber between the inner wall and the outer wall. The side wall is constructed in particular of at least one, preferably a plurality, wall chamber (s) or forms it. In particular, several wall elements each bound at least partially a wall chamber, in particular together with an inner wall and / or an outer wall of the side wall. In particular, a wall chamber has a hollow profile which is preferably closed in cross-section. In particular, partition walls divide the side wall, in particular the cavity between an inner and an outer wall, in wall chambers. In particular, a wall element in each case forms an intermediate wall of the side wall, wherein the intermediate wall preferably connects the inner wall and the outer wall of the side wall to one another. The partition walls extend in a height direction preferably into the region of the pit opening, or up to a pit edge, wherein the intermediate walls may have protruding head elements on an upper side. Partitions have the advantage that a double-walled portion of the side wall is stiffened, especially against lateral buckling. A wall chamber is limited in particular by two intermediate walls and an inner wall and an outer wall. Wall chambers have the advantage that they stiffen the structure of the side wall. In particular, the wall chamber, which forms the storage space, tight against the entry or exit of gases or liquids, especially water or oil, with sealable openings can be provided in the wall chamber. Preferably, the wall chamber meets the fire protection requirements at least the fire resistance class F30, preferably even F60 or F90. In particular, the wall chamber is hermetically lockable, in particular with respect to the pit interior and / or the top of the pit body, preferably withstanding an explosion pressure. In the cavity between the inner and the outer wall, in particular in a wall chamber, a dense drip pan for collecting spilled liquid dangerous goods attached, in particular be used. A drip pan is in particular made of sheet steel, preferably hot-dip galvanized on one or both sides to meet at least the fire resistance class F30. A drip pan has the advantage that a tank can be executed under certain circumstances single-walled, the safety rules are still met and the cavity in a side wall is even better than storage space exploitable.
    In an advantageous development of the second aspect of the invention, the side wall is formed at least in the region of the storage room, in particular the wall chamber, self-supporting. Preferably, a double-walled portion of the side wall, in which a storage space is integrated, formed self-supporting, in particular a removal of the introduced by vehicles above the mounting pit loads on the side wall of the pit body in the ground without additional reinforcement of the side wall structure, in particular backfilling of the side wall hardenable filling material, to ensure. For example, a side wall, in particular the wall chamber, in the region of the storage space having an increased wall thickness, in particular with respect to the remaining region of the side wall of the pit body, preferably by thicker sheets for the inner and / or outer wall or a wall element in this area. It can also stiffening structures, such as frames, ribs, struts or supports, preferably within the side wall, may be provided, which may also be mounted in adjacent to the storage room wall chambers. In particular, the side wall in the region of the storage space, in particular a wall chamber, within which the storage space is provided, is not intended for filling with a filling material. A possibly existing drip tray may additionally have a stiffening effect on the side wall, in particular be firmly connected to this. The lateral edges of a drip pan can be pulled up on the inner sides of the inner and / or outer wall and / or partitions, in particular up to the upper edge of the storage space. In this way, in addition to a seal and an additional structural stabilization of the side wall and the storage space is achieved. It is also conceivable to use an additional container in a wall chamber, which can be firmly connected from the inside to the side wall, wherein the interior of the container forms the inventive storage space. A self-supporting sidewall is preferably sufficiently rigid to meet the mechanical requirements while still providing a storage space integrated therein.
    In an advantageous development of the second aspect of the invention, the inner wall of the side wall has a closable, in particular sealed, maintenance opening between the storage room and the pit interior. A maintenance opening is sealingly closable, for example, with a cover plate, wherein the cover plate is preferably designed so that the fire protection and explosion protection regulations are met. A maintenance opening is preferably arranged in the upper region of the pit interior.
    In an advantageous development of the second aspect of the invention, the side wall, in particular the wall chamber, on a top on a storage space cover. The storage space cover closes the storage room, in particular the wall chamber, tight, preferably hermetic. Preferably, the storage space cover is designed to be passable and has a non-slip surface structure or coating. The storage space cover is preferably movable, in particular designed to be manually or mechanically liftable or automatically, in particular motor, apparently, wherein a closing mechanism can be integrated in the storage room. When the storage space cover is open, liquid dangerous goods, in particular used and / or fresh oil, stored in a tank in the storage space can be pumped off, for example, with a tank truck via a hose which can be connected. It is also conceivable to provide a connection or a passage opening for a tank truck hose in a storage space cover.
    In an advantageous embodiment of the invention, the storage room has a storage room floor with anchoring elements for a tank, which are designed in particular as buoyancy protection. A storage room floor can coincide with a pit floor extending to the outer wall or as an intermediate floor, in particular additionally arranged within the side wall, which can be arranged below or above the level of a walkable intermediate floor provided inside the pit interior. A deep storage room floor increases the storage space and allows the installation of a larger tank for liquid dangerous goods. Within a side wall, preferably in different wall chambers, a plurality of shelves, in particular on different levels in the height direction, for example, step-shaped, can be arranged. The storage room floor can be directly connected to the side wall, in particular the inner, outer and / or intermediate wall, in particular welded, or used or inserted as a separate base plate in the storage room. The storage space floor may be formed as the bottom of a collecting trough, wherein the storage space floor, in particular the collecting trough, can be raised from the storage space, for example provided with lifting devices, such as loops or rings. The anchoring elements are formed, for example, as threaded holes, Klemmverbindungs- and / or Schraubverbindungselemente that can be brought, for example, with pallet feet of a tank, for example via corresponding recesses, positively and / or non-positively engaged. Anchoring elements may be attached as thread blocks on the underside of a storage room floor with corresponding through openings. Anchoring elements on a storage room floor, which is connected to the sides or connectable, have the advantage that they can prevent the buoyancy of a tank in the event of leakage or flooding of the storage room, for example by rainwater, cleaning water or a pipe break in the workshop. Preferably anchored to a storage room floor buoyancy backups, especially rods, up to an upper side of a storage room or a tank. An anti-buoyancy device is designed, for example, as a hot-dip galvanized threaded rod which can be screwed to a top of the tank with a nut with a matching mounting device of the tank.
    In an advantageous development of the second aspect of the invention, at least one sealable wall duct in the storage room, in particular a sealable pipe socket provided in the inner wall, for example, for carrying electrical lines for a level sensor and / or a leak detection device, a filling or Suction line and / or a vent line. A first wall feedthrough for a suction or filling line for a liquid stored in a tank can be arranged in an upper region of the storage space, wherein a steel tube preferably can be connected to a pipe socket in order to protect the line extending therein. A second wall duct for a vent line can be connected to the side of the storage room, in particular with a vent pipe of the tank, and / or can be connected to an outside of the storage room, in particular to the pit interior, with a venting device of the installation pit. Preferably, such a wall bushing is arranged in a lower region of the storage space, since gases flowing out of a tank for liquid dangerous goods are typically heavier than air. Preferably, a wall duct for a vent line above a possibly provided wall duct for drainage is arranged. Wall ducts, in particular for electrical lines, may also be provided in partitions of a wall chamber, which forms the storage space, wherein lines can be laid within the side wall. For example, lines to a central control device of the assembly pit, in particular for a fill level [sensor] or an overfill protection device or a leak detection device, for example vacuum leak monitoring, of the tank are laid through a wall duct or provided for this purpose. A wall penetration is sealable for example by a fire protection foam.
    In an advantageous embodiment of the invention, the storage room has a liquid sensor, in particular a level switch on. The liquid sensor is preferably arranged in a lower region of the storage space, in particular just above the storage space floor or intermediate floor, in particular in a passage opening of the inner wall provided for this purpose. For example, a level sensor is provided as a laterally mounted level switch, in particular screwed into a threaded sleeve, and preferably connected to a mounted in the interior of the mounting pit control lamp. In particular, a level sensor has a float, preferably made of stainless steel with a sunken magnet, wherein the magnet switches a reed contact. Such a magnetically actuated filling level sensor can be hermetically sealed and can detect the liquid level within the storage space or produce a corresponding switching signal for monitoring purposes.
    In an advantageous embodiment of the invention, the storage space on a drainage device, wherein in particular at the height of the storage space floor in the inner wall, a drainage opening, preferably with a ball valve, is provided. In this way, a drainage of the storage space in the pit interior is possible, which extends in particular to a provided in the pit floor sink with outflow. It can also be a gutter system installed in the mounting pit to which the drainage device is connected or into which the drainage opening opens.
    In an advantageous development of the first aspect of the invention, the storage space is recessed below the entry or exit aid against a walk-in intermediate floor, in particular at a front end of the pit interior. A walkable intermediate floor extends in particular above the pit floor and consists for example of a laterally resting grid floor, to which the entry or exit aid preferably leads down from the pit opening. A storage space recessed in comparison with the walk-in intermediate floor has the advantage that the storage space is increased in height and a higher tank can be fitted below the entry and exit aid. Preferably, the storage space extends over the entire width of the pit interior and is particularly limited laterally by the two longitudinal side inner walls.
    In addition, the stated object is achieved by a mounting device according to claim 13.
    In particular, the above object is achieved by a mounting device, in particular for vehicles, comprising - a mounting pit, in particular according to one of claims 1 to 12, with a replaceable in a Bodenausnehmung mono- or multi-part pit body, in particular of steel, the one order having a pit interior circumferential side wall, a pit floor and a pit opening, and - a tank for liquid dangerous goods, in particular an oil tank, characterized in that the tank is integrated into the side wall.
    In particular, the tank is arranged in a storage space which is integrated in the side wall. In particular, the tank is arranged inside the side wall. The tank can be single-walled or double-walled. In the case of a single-walled tank, it is preferable to provide a collecting trough in the storage space which can be dispensed with in a double-walled tank in accordance with the regulations. A tank can be made of steel, in particular stainless steel, or of fiberglass-reinforced plastic, PE (polyethylene), PA (polyamide), wherein a tank wall can additionally have a diffusion barrier. A tank interior and tank outer wall of a double-walled tank can be made of different materials. Preferably, the tank is equipped with a leak indicator, preferably an energy-independent vacuum leak monitoring of the tank interior and tank outer wall, and preferably has a fill level indicator or overfill protection. For reasons of corrosion protection, the tank is preferably hot-dip galvanized inside and outside. The tank has in particular a lid with lifting devices, in particular a dome lid with threaded holes and is preferably suitable for fastening a buoyancy protection, in particular of rods anchored in or on a storage room floor. Such a mounting device according to the invention has the same advantages as previously described in connection with the mounting pit according to the invention. In particular, a tank for liquid dangerous goods by integrating into the side wall space-saving housed in the mounting pit, so that the space required for a mounting device is reduced.
    In an advantageous embodiment of the inventive mounting device, the tank is double-walled and has in particular a leak detection device. A double-walled tank has the advantage that, in accordance with the regulations, no minimum distance to the limiting side walls of the storage room must be maintained. As a result, the tank can use the storage space as completely as possible in a particularly space-saving manner. Furthermore, the dimensions of the tank can be adapted to the geometry of the storage room. In particular, the tank is designed cubic or cuboid. For a double-walled tank with a leak detector can be dispensed with a drip pan, without violating fire safety regulations. Under certain circumstances, by a correspondingly stable and dense storage space, for example, by an additionally inserted into a wall chamber container, in combination with a double-walled tank even a higher safety class, especially fire resistance class, as prescribed achievable, for example for assembly pits in areas with particularly stringent water protection regulations ,
    In an advantageous embodiment of the inventive mounting device, the tank is designed as a multi-chamber tank for storage of various liquid hazardous goods, such as waste oil, fresh oil and / or fuel. A multi-chamber tank may be formed as a unitary tank with a plurality of separate tank chambers or as a battery tank with a plurality of interconnected tanks. It is also conceivable to provide separate tanks, preferably in separate wall chambers of the side wall, in a storage space, wherein the storage space can also be arranged over a plurality of mutually, e.g. can extend through passage openings in partitions, interconnected wall chambers. Such a multi-chamber tank could for each individual tank chamber have separate wall penetrations on the inner wall of the side wall of the pit body, or on common wall penetrations to the
    Montagegrube or their facilities be connected. Through a multi-chamber tank, a mounting device can be used so far more flexible, as various liquid hazardous goods incurred or required for various jobs can be stored to save space in the mounting pit.
    In addition, the stated object is achieved by a use according to claim 15.
    In particular, we the above object solved by the use of a cavity between an inner wall and an outer wall of a double-walled side wall of a mounting pit, in particular precast mounting pit, which comprises a usable in a bottom recess one or more parts pit body, in particular steel, the one around a pit interior circumferential side wall, a pit floor and a pit opening, for the storage of liquid dangerous goods, especially oil, preferably used oil, in a tank.

    In the following description of the invention, the same reference numerals are used for the same and like-acting elements.
    Fig. 1 shows a schematic plan view, or a horizontal cross-sectional view of an inventive mounting device 100 with a mounting pit 1, designed here as a prefabricated assembly pit, for installation, repair or maintenance of vehicles and a tank 4. The pit body 10th the mounting pit 1 is constructed symmetrically to a longitudinal axis of symmetry A. The pit body 10 has a rectangular layout comprising a side wall 20 defining a pit interior 22 with a pit opening 21. The side wall with two end faces 17 and two longitudinal sides 18 and is formed here circumferentially double-walled. The side wall 20 is double-walled with an inner wall 12 and an outer wall 13, wherein the inner wall 12 along the longitudinal sides 18 as a continuous longitudinal side inner wall 121 and along the end face 17 is formed as a continuous end side inner wall 122, while the spaced from the inner wall 12 Längsseitenaussenwände 131 and Stirnseitenaussen walls 132 are formed by angled wall elements 19. The double-walled side wall 20 preferably has a thickness of 10 to 40 cm, preferably 20 to 30 cm, more preferably about 25 cm, wherein the wall thickness in both the height direction, as well as along the circumference of the pit opening 21 may vary. In particular, the wall thickness along the end faces 17 can be different than the wall thickness along the longitudinal sides 18. The pit body 10 can also be constructed asymmetrically, in particular with regard to the arrangement of the wall elements 19. The thickness of a wall element 19, which preferably consists of bent sheet steel, is typically 1 to 5 mm, preferably about 3 mm. The intermediate walls 15 extend in height from the pit bottom 14 into the region of the pit opening 21 or to the pit edge 23. The wall elements 19 are connected to one another via welded connections and to the longitudinal side inner walls 121 and end side inner walls 122. The wall chambers 11 act stiffening for the pit body 10.
    According to the invention, in the side wall 20, here on a longitudinal side 18, a storage space 3 is integrated with a tank 4 received therein for liquid dangerous goods. The storage space 3 is arranged between the inner wall 12 and the outer wall 13 within the side wall 20. In this way, the tank 4 is space-saving integrated into the side wall 20. Those wall chambers 11, which do not form a storage space 3, can be filled with a hardenable filling material, such as lightweight concrete, from above. The wall chamber 11, which forms the storage space 3, as shown in detail section C in Fig. 2, however, is not filled, but remains hollow, so that the tank 4 finds room in it. A tank 4 integrated on a longitudinal side 18 may e.g. Have dimensions of 1.2 m or 2.0 m in height, 0.5 m in width and 0.25 m depth, the depth of which corresponds approximately to the thickness of the side wall 20. A wall element 19 may suitably have a length of approximately 0.5 m, corresponding to the width. A tank 4 integrated on an end face 17 may e.g. Dimensions of 1.2 m or 2.0 m height, 1.6 m width and 0.2 m or 0.5 m depth, the width being approximately the width of the pit body 10 and the depth approximately equal to the thickness of the side wall 20 corresponds.
    Fig. 2 shows a portion of a double-walled side wall 2 according to the detail C of Fig. 1 with three wall chambers 11, of which in the middle wall chamber 11 according to the invention a storage space 3 is integrated with a tank 4 received therein. This wall chamber 11, which is bounded by two side walls 15, the inner wall 12 and the outer wall 13 is designed to be self-supporting, which is achieved here by a larger wall thickness compared to the other wall chambers 11. For example, the inner wall 12 and / or the outer wall 13 in the region of the storage space 3 has an increased wall thickness of, for example, approximately 5 mm compared with the remaining area of the inner wall 12 or outer wall 13, while the wall thickness in the remaining area is e.g. 3 mm. There may be other wall thicknesses and wall thickness differences may be provided. By a self-supporting execution of the relevant wall chamber 11 ensures that even large loads can be derived from the top of the pit body 10 on the bottom in the ground without the side wall 20 buckling at this point laterally and in particular the tank 4 can be damaged , In the relevant wall chamber 11 itself, but also in the two adjacent wall chambers 11, additional stiffening structures can be provided to ensure the structural stability of the storage space 3. The tank 4 is designed here with a double-walled tank wall 42 with a tank inner wall 421 and a Tankaussenwandung 422. As a result, the tank 4 is particularly safe and it can be dispensed with an otherwise required according to the collection tray below the tank 4 within the storage room 3. The side wall 20 has in an inner wall 12 a wall duct 123 in the form of a circular opening into which, for example, a Ruhrstutzen for the implementation of various lines can be used sealingly. FIGS. 3A and 3B each show a schematic front view of a storage space integrated in the side wall 20 on an end face 17 of the mounting pit 1 with a tank 4 received therein. On an underside of the tank 4 is at the pit floor 14, which also forms the storage space floor 27, anchoring elements 28, here designed as threaded blocks on the bottom of the storage room floor 27, anchored so that the tank 4 is secured against buoyancy, for example, when water or out The liquid leaked out of the tank 4 would otherwise float the tank 4. Here, the buoyancy protection is formed by rods 44 attached to the top of the tank 4 on both sides. At the tank lid 43 designed as a dome lid, a vent line 31 is connected and a leak detection device 41 is arranged thereon. A filling line 32 (not shown in FIGS. 3A and 3B, see FIG. 5) is connected to the tank 4 for filling with the liquid dangerous goods, in particular waste oil to be collected. Electrical lines to the leak detection device 41, possibly provided Überfüllsicherung and / or a suction line 32 are feasible through the wall duct 123 from the storage room 3 into the pit interior 22, wherein the wall duct 123, in particular a pipe socket inserted therein, sealing, in particular hermetically sealing, too Close is, for example, with fire protection foam. In Fig. 3B, the front side inner wall 122 is to be seen in a front view, wherein behind the storage space 3 is integrated within the side wall 20 on the end face 17. The storage room 3 is sealed by a storage space cover 26 upwards. In the upper region of the front side inner wall 122, a maintenance opening 25 which is tightly closed by a cover plate 251 is provided, via which the storage space 3 can be accessed as required, in particular for maintenance of the tank 4. On the underside of the storage space 3, a passage opening 124 is shown with a drainage device 30, in particular a ball valve, mounted therein, via which liquid can be drained from the interior of the storage space 3 if necessary. A liquid sensor 29 is designed, for example, as a magnetically actuated level switch, which detects a level of liquid in the storage space 3 and can turn on a control lamp or trigger an alarm. The intermediate wall 15 has vertically spaced passage openings 151, via which adjacent wall chambers 11 are connected so that curable filling material filled from above is uniformly distributed in the connected wall chambers 11 by a chamber. Such passage openings 151 are in the intermediate walls 15, which limit the storage space 3, but according to the spirit of the invention does not exist.
    In Fig. 4 details of a storage space cover 26 and a maintenance opening 25 are shown in a partial sectional view, wherein the cover plate 251 via a screw on the inner wall 12, in particular a front side inner wall 122 or a longitudinal side inner wall 121, sealingly attachable.
    In Fig. 5, an embodiment of an inventive mounting pit 1 is shown with a below an entry or exit aid 2, which is designed here as a staircase, arranged storage space 3 with a tank 4 received therein. The entry and exit aid 2 leads from a pit opening 21 or a pit edge 23, around which an edge profile 24 rotates, obliquely down to a walk-in intermediate floor 16 in the interior 22. The tank 4 is recessed in space over the accessible intermediate floor 16 at anchored to the pit floor 14 via anchoring elements 28 and housed in this way particularly space-saving in the pit interior 22. A tank 4 arranged below the entry and exit aid 2 may e.g. Have dimensions of 1.2 m in height, 1.6 m in width and 0.5 m in depth, the width of which corresponds approximately to the inner width of the pit body 10.
