    The invention relates to a seepage system, preferably to a fascine to be laid underground, with one or more hollow bodies intended to hold a volume free in the ground, in which a liquid, preferably rainwater, to seep down , can be discharged for intermediate storage and seepage, with a channel or one or more rinsing-hollow bodies forming a channel together, and with a deposition device for depositing suspended solids in the liquid. The invention can also be used in a tank, so the volume is not wrapped in permeable material, but with dense foil.
    For intermediate storage and infiltration of rainwater, fascines are often used in practice, which contain manifolds and are either filled with gravel or with infiltration devices (hollow bodies that are protected against contact erosion). Modern collection and seepage systems today often contain modularly constructed hollow bodies of plastic, which together form the static structure (support) of the container and, depending on the application, are wrapped with textile cloth (seepage system) or foils (collection system). Due to the design, these hollow bodies contain a plurality of different stiffeners which provide for the absorption or deflection of load. They are usually designed as cassettes that can be laid or attached on top of each other or next to each other, and together form cavities for the water.
    They are usually made so stable that the surface above can be used as a roadway or parking space. Drainage systems, depending on the connected surface, are heavily loaded with different dirt (suspended solids). The suspended solids deposit inside the cassette due to the low flow rate and can thus clog / fill the cassette so that it does not function as intended. Therefore, there are many different rainwater treatment plants or rainwater treatment plants on the market. These are almost always used before rainwater tanks or seepage systems.
    Drain systems that are partially or not filtered at all come to the actual cassette via a duct (pipe connection or inner shaft). The collected rainwater can be distributed
    DK 2021 00021 U1 -2- virtually free in one, two or three dimensions in cassettes.
    However, the same goes for dirt.
    Therefore, in the case of rainwater tanks and seepage systems, it is very important that the system is cleaned of - added dirt at regular intervals.
    Infiltration plants in particular have a tendency to coalesce due to debris distributed over the bottom.
    It is almost impossible to clean such a surface with colmation.
    This means in the long run that infiltration of rainwater through adjacent contact surfaces in the ground no longer works properly.
    A solution that is sometimes suggested is to rinse with a high-pressure cleaner, but this usually only means that dirt is displaced - but not completely removed.
    From DE 10 2005 006 202 A1 a built-in infiltration system is known, in which a deposition device is provided in a channel so that suspended solids can be deposited.
    The deposition device consists of a non-permeable depression or gutter at the bottom of the channel and of openings (holes, slits) in the sides.
    This causes suspended solids to deposit and can be removed at a later time with a rinse.
    A disadvantage, however, is that the dirt is kept constantly in motion by the seeping rainwater, comminuted as a result of constant rubbing and thus eventually led through the openings to the fascine, e.g. in case of heavy rain showers.
    This causes the textile fabrics to coalesce at the transition from the storage elements to the adjacent soil layer so that the rainwater cannot seep down.
    This device constitutes the preamble of claim 1. DE 202005 010090 U1 relates to a fascine element for infiltrating surface water with at least one hollow chamber delimited by the permeable side walls of the fascine, for intermediate storage of - infiltrated surface water, whereby this hollow chamber is at least substantially braced with vertically placed support elements when mounted correctly and the fascine element has a continuous inspection channel.
    DK 2021 00021 U1 -3- EP 2 385 178 A2 relates to a device which has areas between the posts, whereby the posts are placed next to each other in a predetermined direction. WO 2005/040501 A1 relates to a drainage tank with at least one permeable wall and a hollow body projecting into the tank. The wall of the hollow body has a lower shell part and an upper section having passage openings. EP 2 687 642 A1 relates to an irrigation and / or drainage device which has a box container with a base wall which has perforations and container side walls which have vertically made perforations and which are connected as an integral part to the base wall. US 4,145,157 A discloses a modular drainage field section and a method of making a drainage field section with upper and lower housings interconnected to form any drainage field section.
    The object of the invention is to improve such an integrated infiltration or collection device so that dirt is kept more securely away from the actual cavity and can be removed more easily. The object is achieved according to the invention by the characterizing part of claim 1. Preferred embodiments of the invention are discussed in the subclaims. According to the invention there is thus provided a seepage system, preferably for a fascine to be constructed underground, with one or more hollow bodies intended to hold a - volume free in the ground, in which a liquid, preferably rainwater, to seep down , can be discharged for intermediate storage and seepage, with a channel or one or more rinsing-hollow bodies which together form a channel, and with a deposition device for depositing suspended solids
    DK 2021 00021 U1 -4 substances in the liquid, whereby the depositing device is at least partially liquid permeable, whereby depositing chambers are provided, and whereby a) the depositing device is a grid which is in the channel and divides the channel into an upper flow chamber and a lower deposition chamber, or —b) the deposition device is a membrane, a cloth, a fabric, a fabric or a nonwoven fabric, preferably of geotextile or metal, and wherein the flushing hole body has structural elements which act as deposition chambers when the flushing hollow body is enclosed by the deposition device. What is important about the invention is that a gutter should not be provided in which deposits are constantly flushed, but that deposit chambers are provided which allow a stabilization of dirt or deposits. The bottom of the duct and its vertical walls are provided with a plurality of sludge or deposition chambers, which thoroughly stabilize the deposited dirt before this can be purposefully removed during a maintenance process. A further displacement of the deposits in the direction of the actual cavity or the outer fabric does not take place.
    Thus, the deposited particles are also not subjected to further friction or comminution processes. This would possibly mean that the degraded particles at some point are small enough to penetrate the inner membrane (textile fabric). This in turn would cause colmation processes in the outer nonwoven fabric of the system.
    Thus, in an alternative of the invention, a liquid-permeable foil, a cloth, a fabric, a membrane or a textile cloth is used, which extends over larger distances within the volume and which preferably extends below or next to a channel. Liquid permeability is not necessary everywhere; it may be enough to have this at least in sections. The duct can be formed in a single piece as a kind of pipe or formed of several parts. A channel composed of several rinsing-hole bodies is preferred, which are uniformly positioned so that together they form the channel which extends over a longer stretch in the volume. This channel can then be used for inspection or for rinsing and removing deposits. The foil can be composed of single pieces or of a larger piece.
    DK 2021 00021 U1 -5- Especially when using hollow bodies, it is sufficient if the rinsing hollow bodies at the bottom and on two vertical sides are enclosed with foil / membrane.
    This can preferably be prefabricated or carried out during assembly, so that the rinsing-hole bodies forming the deposition device can easily be enclosed with foil / membrane.
    The individual foil sections do not necessarily have to be connected to each other in a sealing manner, as the foil pieces are held in place by the adjacent hollow bodies.
    The foil pieces thus form a channel which is permeable to the liquid, i.e. usually rainwater.
    Co-washed suspended solids, deposits, wear parts or dirt cannot penetrate the foils, thus acting as a filter that retains solids.
    The solids can thus not penetrate into the actual volume, but are retained in the channel.
    Thus, the great advantage of the invention is seen: Since there are also deposition chambers in addition to the foil / membrane, in the flow direction of the channel, the solids deposit here.
    These chambers are obtained, for example, by using conventional element systems for fascines such as the ENREGIS® / X-Box or the ENREGIS® / Controlbox inspection channel offered by the patent applicant.
    If the duct elements are enclosed on the two vertically placed walls and underneath with foil / textile cloth (U-shape), deposition chambers remain between the duct opening and the underside of the elements and on the sides of the elements thanks to the many struts, where - the particles can deposit and settle thanks to a lower flow rate.
    The flush hollow bodies which form the channel and which are enclosed are ideally directly or indirectly connected to the connection to the supply line.
    This can also be done via an inner shaft or a piece of pipe inside the container.
    A channel or several channels can be provided, which then run vertically relative to each other or parallel to each other.
    However, it should always be ensured that all channels can be easily reached from the top to the flush.
    The length of the channels can be freely selected.
    If these do not end up at the end of the volume at the ground cloth, make sure that a barrier (dense or liquid permeable) is also provided for the still dirty rainwater at the end of the channel.
    In a preferred embodiment of the invention, not only a single conduit of hollow bodies is enclosed with foil / membrane, but also the hollow bodies which are placed vertically above the conduit. These sides thus also form a kind of higher filter space, so that a significantly larger amount of water can be filtered by a heavy rain shower than in the "flatter" variant. Foil / membrane can also be enclosed in sub-areas (horizontally / vertically). This may depend on the project and usually aims to deal with peak water situations with high water pressure.
    The inlet ducts can also be equipped with additional flow and deposition optimizing elements. These can be, for example, flow dividers, bulging walls or sludge drainage walls. These constructions are used for a hydraulic and qualitative optimization in the ducts.
    In an alternative embodiment of the invention, a lattice-shaped element located inside a channel is used, instead of a textile cloth enclosing the channel. This grid extends along the channel and divides it into an upper flow chamber and a lower deposition chamber. Carried suspended solids fall through the lattice and deposit. The collection effect - is improved by providing structures at the bottom of the channel, which form obstacles and thus slow down the flow rate. These can be grooves, elevations, depressions or similar rough surfaces between which the solids can be deposited. The special designs of the bottom can form a kind of sludge chambers that can subsequently be rinsed clean. Other advantages, characteristics or uses appear from the following description of the figures. Here shows:
    Fig. 2021 00021 U1 -7- FIG.
    In a seepage system according to the technical condition Figs. 2 shows a seepage system according to a preferred embodiment of the invention,
    FIG. 3 is a detailed view of the system of FIG. 2, FIG. 4 shows a further seepage system according to the preferred embodiment of the invention, and
    FIG. 5 shows an alternative embodiment of a duct in a seepage system according to the preferred embodiment of the invention.
    FIG. 1 shows a seepage system 1 according to the technical condition (fig. 2 according to DE10 2005 006 202 A1), where rainwater from a roof after a cleaning step is introduced into the cavity 2 for seepage.
    In the volume / cavity 2 there is a deposition device 3, which here consists of a gutter which is open upwards, but closed backwards in the direction of flow, of non-liquid permeable material, which has an opening row 4a at a certain height and above it another opening row 4b .
    The rainwater remains in the gutter and is discharged only via the opening rows 4a and 4b.
    Thus it is achieved that dirt - accumulates at the bottom of the gutter and does not flow with the actual volume 2. Fig. 2 shows a seepage system 1 according to the invention seen from above.
    In FIG. 2 above shows sections A-A.
    It can be seen that the volume 2 is created underground and is filled with hollow bodies 5. This can be, for example, ENREGIS® / X-Box, which are so stable that the volume 2 is kept free and - the rainwater flows through.
    The cassettes are enclosed with a liquid-permeable textile cloth against the ground, on the outside and upwards, where the volume is in contact with the ground, which allows the water to slowly seep down.
    In the middle of the seepage system 1 there are a series of flushing hole bodies 6, which have the same dimensions as the hollow bodies 5, but a through-opening,
    DK 2021 00021 U1 -8- which together with the other rinsing hollow bodies 6 in the same row form the channel 7, which here extends over the cavity 2 and which can be used for inspection and rinsing.
    The access to the channel 7 takes place via the telescopic cover 10. Examples of dimensions are shown in Figures 2 to 4. According to the invention, a liquid-permeable textile fabric is now provided as a deposition device 3, which is located below the rinsing hollow bodies 6 and next to the rinsing hollow bodies 6. encloses, so to speak, the channel 7 U-shaped, which is formed by the row of flushing hollow bodies 6. Leaking rainwater flows through the channel 7 and can flow down into all hollow bodies 5 lying next to it or below it, and fill these as the fabric allows the liquid to penetrate.
    However, as the textile fabric retains solids, suspended solids, dirt and wear parts remain safe in this textile fabric 3, where they accumulate at the bottom and in the lower area.
    Since the textile cloth is placed outside the structural elements of the rinsing-hole bodies 6, the solid particles collect in undercuts, in holes and on the stiffeners of the rinsing-hollow bodies 6, ie. in the deposition chambers 8, which is better seen in fig. 3, and can deposit here.
    The solids can be removed again with regular rinsing of the channel 7. Figs. 3 shows at the top section B-B of the seepage system 1 in fig. 2 and enlarged details below.
    Here the deposition device 3 is seen, i.e. the textile cloth marked thick as a "U". It comprises the channel 7, which is formed by the row of the rinsing-hole bodies 6. Within this textile cloth 3 there are the deposition chambers 8. Within the channel 7, possible inlets 9 of the sizes DN 110, DN 160, DN 200 and DN 315 can be seen. . 4 shows a further embodiment of a seepage system 1 according to the invention, whereby not only the rinsing hollow bodies 6, which form a channel, but also the hollow bodies 5, which are in a row above the channel, and the hollow bodies 5, which are located in a row above, is enclosed by the textile fabric that acts as a filter.
    Like the deposition device 3, the textile fabric again has a U-shape, but considerably longer sides.
    In the case shown, the textile cloth extends over two, yes here even three layers of hollow bodies 5 and 6, to the upper edge of the volume 2 and
    DK 2021 00021 U1 -9- abuts directly to the telescopic cover 10. The channels 7 are again clearly visible and in the enlarged detail view the textile fabric that functions as a deposition device 3, clearly marked in U-shape, and the deposition chambers 8.
    FIG. 5 finally shows a detail in yet another variant of the infiltration system, where not a liquid-permeable textile fabric is provided, but a permeable grid 11 in an inlet channel 7. Suspended solids and liquids are separated here by the liquid flowing through the channel 7 (mainly a pipes), whereby suspended solids or dirt fall down through the grid 11 and remain at the bottom of the channel 7 or deposit between the extra mounted - structures and remain there. The grid 11 is preferably located at the bottom of the channel 7 and generally extends over the entire length of the channel 7. The channel 7 can, as stated above, be composed of several flushing hole bodies. But it can also consist of a piece or be inserted into the volume in prefabricated lengths. It can be placed in front of the actual fascine, but also inside it.
