    OBJECT OF THE INVENTION
    The present invention relates to a gutter passage, whose obvious purpose is to minimize damage to possible vehicle impacts when they leave the road and fall into a ditch, specifically in areas where underground passages are arranged for rainwater and the like that give continuity to the driving that determines the gutter.
    The object of the invention is to provide the public works sector with an easy-to-assemble, safe and elastic fastener passage. BACKGROUND OF THE INVENTION
    Conventional ditch passages are usually made up of a vertical concrete wall, with a hole for the passage of water and two lateral wings, also made of concrete to channel the water towards the hole in the wall.
    This structure is completed with a top trellis that can be based on concrete joists, metal grilles, etc., by way of meshes.
    In addition, the structure has a slope in descent from the area of the vertical wall to the free end of the side wings, so that a vehicle that leaves the roadway, rolls along the ramp that forms the slope of the salvage passage ditches and thus avoid the impact against the vertical facing.
    Therefore, one of the most conflicting points regarding the severity of accidentsIt is the exit of the road by the vehicles and the impact of these against steps saves
    ditches, so that the vertical face of these and the great rigidity they present make the vehicle absorb almost all the energy of the impact, assuming serious damage not only for the vehicle but for its occupants.
    In order to alleviate these circumstances, various improvements of the steps have been designed, both in situ and prefabricated, being able to mention, for example, the ditch-guard step described in the Spanish utility model ES 1071977 UY in the patent ES 2222109 A 1, of so that in the first document the passage consists of a concrete module with a vertical front wall with holes facing the communication pipe between ditches and two side walls that form vertical side wings, these walls being triangular, determining an inclined upper edge from the bottom of the gutter to the upper edge of the passage, including between said lower edge and the edge of the upper wall longitudinal bars that determine openings and form a ramp for the wheels of the vehicle that circulates through the gutter.
    As for the gutter passage described in the patent ES 2222109 A 1, it is constituted from a structure like the one previously mentioned, with the divergent side walls outward and providing a grid that is hingedly fixed to a support frame that is fixed on the upper concrete structure.
    These ditches can also be prefabricated, and always with the purpose of restoring the vehicle to the road without impacting the vertical concrete wall of the passage, with the advantage of moderating the severity of the accident, but with the inconvenience of that the vehicle is out of control, being able to produce accidents by impact with other vehicles. DESCRIPTION OF THE INVENTION
    The gutter passage proposed by the invention, based on the concrete structure that forms the vertical wall and the side walls or wings with the upper ramp grid, presents a series of improvements that solve the above-mentioned problem, in addition to getting new and important benefits compared to conventional steps, as will be seen throughout this description.
    One of the improvements is that the side walls or wings are mounted on a concrete slab, depending on the foundation slab, presenting it in one of its
    5 ends and in proximity to its sides, two sections of channels in which they are located and position respective pieces of "U" sheet, which embrace the front edges of the walls or lateral wings of the pass-ditch, being also located the end of these walls or lateral wings inferiorly in those referred sections.
    10 The fixing of the wings or side walls to the foundation slab is done by means of angular "L" pieces, in which one of whose wings is fixed to the foundation slab while the other wing is fixed to the side of the respective wing or side wall.
    Obviously, in fixing the wings or side walls to the foundation slab, through the "L" profiles, bolts are involved that are through the wings themselves
    or side walls and are definitely fixed by washers and appropriate nuts, with the special feature that the holes in which the bolts are housed are larger in diameter than said bolts, so that they are arranged with great clearance with respect to the hole in which are introduced, producing an articulated contact that
    20 allows the forward movement of the wings or side walls when a collision occurs, until said bolt touches the hole wall, at which time the breakage of such bolt occurs due to said thrust derived from the collision.
    In fixing the angular profiles in "L" to the foundation slab, a rail in 25 "c" embedded in the foundation slab itself is produced during its manufacture, being in that lane in "c" where the anchor is fixed or fixed respective end of the corresponding fixing bolt.
    On the other hand, the wings or side walls, of concrete as well as the foundation slab and of course the front and vertical wall, have their inclined front edge, forming a
    30 horizontal angulation of approximately 75 °, thereby allowing its coupling to factory works, that is to say the vertical walls previously made "in situ", and having an outstanding slope of values between 0% and 13%.
    As for the upper grid, it is constituted from a frame fixed on the upper edge of the two side walls or wings of the gutter passage itself, in which frame metal grid modules are mounted, preferably three modules that are they correspond to the holes that delimit the holes or holes of the wings or concrete side walls themselves, since four lateral profiles with their corresponding bolts participate in fixing it.
    The grid is mounted on the frame referred to and recessed as it was said on the corresponding upper edge of the wings or side walls closing the grid itself by means of bolts established on one of the sides.
    The mounting of the upper trellis allows the tilting and dismantling with respect to the frame anchored at the upper edge of the walls or side wings of concrete, allowing cleaning, opening and corresponding maintenance.
    The frame and grid described also participate in lateral dragging when they are closed and collaborate together with the lateral wings to avoid the efforts that produce the thrust of the lands located in the intrados of the fins.
    All the metallic elements that form the grid and the frame are galvanized to prevent corrosion.
    The grid is calculated to withstand heavy traffic loads that may occur due to auxiliary maneuvers in the works, either by the conservation or by the users who have to use such pass-through steps to enter farms, etc. , with heavy machinery.
    In summary, apart from the advantages and benefits of the step described above, the following can be mentioned:
    • The entire structure is prefabricated, allowing rapid execution avoiding road cuts, providing an execution time of three days per step and can be done with a single gang.
    • The whole set of the passage is obtained in concrete, which allows greater durability.
    • The concrete side walls or wings are intended to withstand earth thrust efforts of up to 1.60 meters.
    • The anchoring of the side walls or wings to the lower slab, which constitutes the corresponding foundation, also prefabricated, allows the mobility of such side walls or wings in the event of an impact, absorbing the energy of the impact, so that said fixation can be considered as elastic .
    • The upper grid has a double frame, made in modules, so that the outer frame is anchored to the upper edge of the side walls or concrete wings, and the interior, joined by hinges to the side opposite the road, allowing disassembly of the grid assembly for maintenance, without the need for lifting machinery or auxiliary means, all in such a way that on the opposite side of the hinge, the connection between frames is done by means of a bolt.
    • The folded and "U" shaped sheet after its fixation to the vertical wall allows the prefabricated to be adapted to the longitudinal slope of the gutter and to the possible inclination of the passage, so that these sheets, in the event of an impact, can be deformed by absorbing part of the energy of the vehicle and allowing its arrest.
    • Also say that the basic module that forms the side walls can be complemented with modulated supplements of shorter length and that are anchored to the basic module at the points where the frames of the upper grid would be anchored, the termination being blown. DESCRIPTION OF THE DRAWINGS
    To complement the description that will then be made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical implementation thereof, a set of drawings is attached as an integral part of said description. where, for illustrative and non-limiting purposes, the following has been represented:

    Both the foundation slab (1), as the wings or side walls (2) are made of concrete and the configuration of said wings or side walls is triangular, with its leading edge or edge (2 ') inclined and its edge or upper edge (2 ") staggered for the assembly of a frame (4) that constitutes a mounting element for modules (5) of the upper frosting (3), as will be discussed later.
    The fixing of the wings or side walls (2) on the foundation slab (1) is carried out by means of angular "L" profiles (7), through one of whose wings is fixed to the foundation slab (1 ), while through the other wing it is fixed to the wing itself or side wall (2), as can be seen clearly in Figures 1 to 4.
    As is evident, this fixing is carried out by means of bolts (6) through the wings or side walls (2), to be fixed inside by means of corresponding nuts and washers, while the foundation slab (1) , the bolts (6) are fixed on "C" profiles or rails (12), as shown in Figure 8.
    In the assembly of the wings or side walls (2) involved "U" plates (8) that are anchored to the vertical and front concrete wall (9), and also embrace the front part of the wings or side walls (2 ), fixing these through screws or appropriate pins, with the special feature that these "U" plates (8), as well as the lower edge that is embraced by these of the wings or side walls (2) are positioned in sections of channel (10) established for this purpose on the leading edge of the foundation slab (1), in proximity to its lateral edges, showing in figure 5 said foundation slab (1) with its end channels (10) thus as with the housings (11) in which the rails are positioned in "c" (12).
    Regarding the fixing of the wings or side walls (2) to the foundation slab (1), say that the fixing is done through the angular profiles in "L" (7) on both sides, that is to say inside and outside, as shown in figure 4.
    Finally say that in relation to the grid (3), it is formed by several modules
    (5) and is mounted, as already said, on the upper frame (4) arranged and embedded in the upper edge of the wings or side walls (2), the frame (4) remaining on said frame (4)
    5 commented grid (3) and specifically the modules (5) with side anchors and opening means by hinge and in pairs, with the particularity that those grid modules (5) are formed based on rounds, forming an electro-welded mesh .
