Description

The invention relates to a device for forming with a vehicle, in particular a car, a truck and / or a tired or equipped with chain drive construction vehicle accessible, for drainage and / or water storage purposes introduced into the ground cavities. In particular, the invention relates to a device for surface infiltration of precipitation or surface water, the device should be passable by vehicles.

For the storage of large, short-term accumulating amounts of surface water, it is known to create voids in the ground, which receive the surface water in the manner of a receiving water, in order to then "metered" to pass into the sewer. By this measure, the sewer system does not need to be designed for the absorption of extremely large amounts of water, which reduces installation costs.

It is known to use for the formation of cavities in the ground for dewatering and / or water storage purposes cube or cuboidal plastic mesh boxes, which are arranged side by side and stacked in the ground create a free space (see, eg. DE-A-10 2009 052 724 . EP-B-0 734 478 and WO 2007/118894 ). Such mesh boxes have in addition to their function of creating free or cavities on a certain stability, so that the area above the cavity remains passable, as for example in parking lots or the like. With vehicles passable surfaces is the case. However, the soil and possibly also the pavement or the asphalt topsoil takes over the task of load distribution.

Furthermore, it is known, drenched, d. H. to create non-sealed surfaces (such as pavement, asphalt, etc.) by plantable grid bodies (grid plates or boxes) that form the uppermost layer of the soil.

The object of the invention is to improve the navigability of the device to the effect that the actual load-carrying layer above the water storage or absorption serving lattice boxes to be able to run as thin as possible.

• At least a first layer of plantable first grid bodies above the grid box arrangement for following the grid box arrangement with a vehicle,
• - In each case adjacent first grid body to form a load-bearing composite shear stiff and / or rigidly connected to each other and / or abut against each other to form a load-bearing composite and
• - Wherein the at least one first layer of grid bodies free of soil (soil, stones, etc.) rests on the arrangement of the plurality of grid boxes.

According to the invention, at least one and preferably exactly one layer of plantable first grid bodies to be arranged above the cavity, which is filled for drainage and / or water storage purposes with known grid boxes, which are inventively shear stiff and / or rigidly interconnected or lean against each other. Such a composite of first grid bodies forms a load-bearing layer, which is now arranged according to the invention on the grid boxes, which in turn form the cavity for drainage and / or water storage purposes. In this sense, therefore, the cavity is not entirely hollow, but filled by grid structures and provided in the uppermost area (uppermost layer) with plantable grid bodies, the tops then form the drivable seepage surface.

The innovation can be seen in the fact that plantable grid body such as plastic lawn screen meshes by shear stiff connection to a load-bearing composite, which rests directly on the arrangement of drainage and / or water storage grid boxes. Possibly. For example, a water-permeable textile such as so-called geotextile can be arranged between the plantable grid bodies and the drainage and / or water storage grid boxes. The latter prevents the penetration of soil into the area to be kept clear by the lattice boxes for drainage or interim water storage.

Advantageously, the connection between the grid bodies and the grid box arrangement is also designed to be shear-resistant, which expediently by interlocking Projections and corresponding recesses and thus positively achieved.

In a further advantageous embodiment of the invention can be provided that the formation of the load-bearing composite each adjacent first grid body by complementary connecting recesses and - projections of their mutual, respectively adjacent edges are positively connected to each other.

Alternatively or additionally, the load-bearing composite of the first grid bodies can also be achieved in that respectively juxtaposed first grid body are positively connected to each other by connecting elements.

In the two alternatives described above, adjacent grid bodies of one or each layer are connected to each other directly in a shear-resistant manner. Alternatively, in turn, a further layer of plantable first grid bodies may be provided, which is arranged on or below the first layer of grid bodies, wherein the grid body is at least the upper of the two layers for shear-stiff and / or rigid connection and / or shear-resistant system both layers are arranged laterally offset from one another and a grid body of a layer with respect to each at least two grid body of the other layer is arranged overlapping. The overlapping arrangement of the grid body of one layer relative to the grid bodies of the other layer results in a shear-resistant composite. Again, that the grid body of one layer are positively connected to the grid bodies of the other layer and thus the shear stiff arrangement is realized.

As already indicated above, it can be provided that a water-permeable textile layer, in particular a fiber fleece layer, a woven fabric or a geotextile, is arranged between the at least one layer of grid bodies or, in the case of several such layers, between the lowermost layer of the grid body and the arrangement of the grid boxes is.

As a rule, a waterproof textile, as described above, is advantageously also wrapped around the entire arrangement of grid boxes, which prevents the penetration of soil into the grid box arrangement.

In a further advantageous embodiment of the invention can be provided that the grid body of at least one layer of grid bodies or, in several layers, the grid body of the uppermost layer of grid bodies are planted and / or filled with soil and / or with an organic / inorganic mixture.

To achieve the above object, according to a further aspect of the invention, an apparatus for the formation of drivable, for drainage and / or water storage purposes introduced into the soil cavities proposed, wherein the device is provided with

• - An arrangement of several side by side and possibly also stacked grid boxes for drainage and / or water storage purposes and
• At least one first layer of plantable first grid bodies on the grid box arrangement for following the grid box arrangement with a vehicle at the level of the earth's surface,
• - Wherein each first grid body having a bottom wall with a towering from this, peripheral edge web and also rising from the bottom wall, intersecting lattice struts, each extending between opposite portions of the edge web and are connected thereto and adjacent, one-sided and open at the top Forming chambers for receiving at least among other natural soil and / or granules for retaining heavy metals and / or oils and / or fuels, which are interconnected by recesses in the lattice struts, wherein in the bottom wall for each chamber at least one opening is formed.

According to the invention according to this aspect is provided on a grid box arrangement, which is spent to form a cavity in the soil, as a topmost layer to provide several stable and load-bearing grid boxes, by using vertically aligned strips of material in particular plastic for the lattice struts and a peripheral edge is extremely stable. These first lattice boxes have a bottom wall, from which a peripheral edge web rises. The area bounded by the edge web is provided with intersecting lattice struts which are formed as material strips standing on one of their side edges. As a result, upwardly open chambers for receiving at least, inter alia, natural soil and / or granules for the retention of heavy metals and / or oils and / or fuels are formed. The individual chambers may expediently be connected to one another by recesses in the lattice struts, so that there is a fluid exchange. The chambers ensure a plantable surface infiltration of precipitation and / or surface water and are also passable. In particular, the lattice struts are shear stable so that they withstand the shear forces associated with rotating steering wheels or about spinning drive wheels of vehicles occur.

In an expedient development of the invention, at least one second layer of plantable second grid bodies can be provided, which rest on the at least one first layer of first grid bodies, wherein every second grid body has an upstanding, peripheral edge web with intersecting grid struts arranged within the area bounded by this comprising adjacent, open on both sides chambers which are interconnected by recesses in the lattice struts, projecting from the edge web and / or the lattice struts of the second lattice body to one side of the same positioning projections, which in arrangement of a second grid body on a first grid body of immerse itself in chambers of the same above and / or immerse each other in the arrangement of two second grid body from above into chambers of the other second grid body, and wherein in both arrangements, the chambers of the successively positioned first and second Grid body aligned with each other and grid struts of each one grid body supported on the lattice struts of the other grid body.

In a further advantageous embodiment of the invention, a lower first layer of juxtaposed first grid bodies and at least one second layer of juxtaposed second grid bodies may be provided, which are arranged on the first grid bodies or on the second grid bodies of a lower further second layer, wherein the first and second grid body are arranged in a composite and a second grid body extends over a plurality of first grid body or offset from two juxtaposed first grid bodies is arranged and at least partially extends beyond this or a second grid body of an upper second layer over a plurality of second grid body one extends lower second layer or offset from two juxtaposed second grid bodies of a lower second layer is arranged and at least partially extends beyond this.

In a further advantageous embodiment of the invention, the edge webs of the first and second grid body having their respective chambers associated recesses.

In a further advantageous embodiment of the invention, it is conceivable that two juxtaposed first grid body and / or, if present, second grid body are mechanically connected to each other by connecting elements, which are insertable into two mutually aligned edge web recesses of the grid body.

As already mentioned above, the chambers of the first grid bodies may be filled with a granulate which serves for the retention of heavy metals and the absorption of oils and / or fuel. The grid boxes arranged below the first grid body can also be filled with this material, but this is not absolutely necessary. The chambers of the first grid body are provided with holes that allow the flow of rainwater into the underlying grid boxes. The lattice boxes may have openings in extension or in alignment with the openings of the chambers. If necessary, the granulate or the bed can be removed from the chambers of the first grid body and, via this, from the grid boxes, for example by suction.

In a further advantageous embodiment of the invention can be provided that the first grid body by a positive connection with the grid boxes on which rest the first grid body, are arranged shear resistant, it being advantageously provided that the positive connection projections on a first grid body and the projections receiving receiving recesses a grid box or vice versa.

The inventively provided drivable construction or superstructure on the grid box arrangement is expediently composed of two different types of lattice body, namely at least one first lattice body and at least one second lattice body. These grid bodies are arranged side by side and one above the other in individual layers, in which case the lowermost layer is composed of the first grid bodies, while each further layer arranged above the lowermost layer consists of a plurality of second grid bodies. The particularity is that the grid body of adjacent layers are not aligned with each other in height extension, but are arranged offset to one another, so that a grid body composite of composite constructed and assembled first and second grid bodies arises or may arise. For positioning and shear-resistant and thus stable arrangement of adjacent layers of first or second or from each first or respectively second grid bodies, the first and second grid body to one of its sides projecting positioning projections, which mechanically with the grid bodies of each adjacent layer of grid bodies interact. Both types of grid body in this case have a peripheral edge web, wherein intersecting grid struts within the area defined by the respective edge web are arranged, which are connected to the respective edge web. Preferably, the intersecting lattice struts form a regular structure. The intersecting lattice struts of both lattice body types define adjacent chambers, wherein in the case of the first lattice body, these chambers are closed on one side, since the first lattice body has a bottom wall, from which the peripheral edge web and the intersecting lattice struts rise. In the respective regions of the bottom wall assigned to the individual chambers, these have at least one opening. Furthermore, the intersecting lattice struts are provided with recesses or openings, so that adjacent chambers are in fluid communication with each other, so are interconnected. In the case of the second grid body eliminates the bottom wall, so that the adjacent chambers formed by the lattice struts are open on both sides. Again, the grid struts are provided for connection of adjacent chambers with recesses or openings.

The intersecting lattice struts of the second lattice body are provided with the protruding positioning projections which, when two second lattice bodies are arranged one above the other or in the case of a second lattice body, dive into a first lattice body into the chambers of one of the two second lattice bodies or into the chambers of the first lattice body , wherein they preferably bear against the grid struts defining these chambers laterally. For a shear-resistant, stable, three-dimensional grid body structure is created, the strength and stability is given by the offset and / or twisted arrangement of the grid body adjacent layers. This grid body structure or superstructure in combination is particularly advantageous in the application as with an inorganic / organic mixture (plantable) grid body for receiving traffic loads advantage. But in other applications, it may be advantageous that the grid body are compact and stable. On the grid body acting loads (such as by vehicles when the grid body in the soil to prevent compression of the near-surface ground zone in traffic areas) are forwarded via the adjacent grid struts of the superimposed grid body into the existing from the first grid bodies bottom layer, where be distributed over the bottom wall flat in the arrangement of grid boxes at only minimal height.

However, the invention also provides only one layer or multiple layers of first grid bodies of the construction described above.

As already mentioned above, it is expedient (but not absolutely necessary) if and / or that the lattice structures of both lattice body types are identical and uniform. Then the individual grid bodies can be offset by the "grid dimension" or arranged in a twisted manner to form height-variable grid body arrangements (composite arrangement).

• – eine unterste Lage aus nebeneinander liegenden ersten Gitterkörpern und
• – gegebenenfalls mindestens eine zweite Lage aus nebeneinander angeordneten zweiten Gitterkörpern, die auf den ersten Gitterkörpern bzw. auf den zweiten Gitterkörpern einer unteren Lage angeordnet sind,
• – wobei die ersten und zweiten Gitterkörper im Verbund angeordnet sind und ein zweiter Gitterkörper sich über mehrere erste Gitterkörper erstreckt oder versetzt gegenüber zwei nebeneinander liegenden ersten Gitterkörpern angeordnet ist und sich zumindest teilweise über diese hinweg erstreckt bzw. ein zweiter Gitterkörper einer oberen zweiten Lage sich über mehrere zweite Gitterkörper einer unteren zweiten Lage erstreckt oder gegenüber zwei nebeneinander liegenden zweiten Gitterkörpern einer unteren zweiten Lage versetzt angeordnet ist und sich zumindest teilweise über diese hinweg erstreckt.

According to an advantageous embodiment of the invention, the passable superstructure on the grid box arrangement thus characterized by

• - A lowermost layer of juxtaposed first grid bodies and
• If appropriate, at least one second layer of juxtaposed second grid bodies which are arranged on the first grid bodies or on the second grid bodies of a lower layer,
• - Wherein the first and second grid body are arranged in a composite and a second grid body extends over a plurality of first grid body or offset from two juxtaposed first grid bodies is arranged and at least partially extends beyond them or a second grid body of an upper second layer over a plurality of second grid body of a lower second layer extends or offset from two adjacent second grid bodies of a lower second layer is arranged and extends at least partially over this time.

In order to laterally delimit or laterally "close off" the upper body according to the invention, it is expedient to use at least one L-shaped side wall element which abuts against the side surface of the upper body formed by edge webs of the first and second grid bodies of different layers or there with at least some the edge webs and some of the grid body is connected. The L-shaped side wall element has a large-area and a smaller-area leg, which are substantially perpendicular to each other. The sidewall member may be perforated or provided with apertures to assist in horizontal water distribution.

As already mentioned above, adjacent chambers of the respective grid body are interconnected by means of apertures or recesses. Such recesses or openings are expediently formed in the edge webs of the two types of grid body. All of these openings or recesses serve for the horizontal permeability of the grid body for the medium to be treated (such as surface or rainwater horizontal water distribution). The vertical distribution of water via the chambers of the superimposed grid body, which expediently with each other be aligned or arranged offset to one another, wherein they overlap in any case, and thus a vertical passage of, for example, surface water or rain through the grid body is possible. If the water has thus reached the lowest position of the grid body, it can escape from the chambers of the bottom layer, which consists of the first grid bodies, through the arranged in the bottom wall openings into the ground.

However, the edge web recesses can also be used to mechanically connect adjacent grid bodies of a layer. For this purpose, connecting elements can be inserted into mutually aligned edge web recesses which, for example, fix the two relevant grid bodies to each other according to the principle of gripping behind the edges of the edge web recesses.

The inventively proposed drivable upper body of the grid box arrangement has due to the possibility of its construction in the composite extremely high stability and equalization of the load distribution directly in the upper body. Due to the staggered arrangement of superimposed grid body such that a grid body spans two or more underlying him, the load is already distributed in the upper body itself. This load may be, for example, wheel loads of (especially heavy) vehicles.

In the aforementioned application example, i. As the earth's surface, the superstructure body, as already mentioned above, is filled with a mixture of inorganic and organic constituents for the retention and purification of incoming liquids or pollutants. The upper body according to the invention allows its refilling (after replacement of the previously filled mixture), without the upper body must be removed. Another advantage of the application described above is that even a partial replacement of grid bodies of the upper body is possible without disassembling the entire installation. Thus, for example, the uppermost layer of mesh bodies can be exchanged while the lower layers remain untouched.

With regard to the structure geometrically regular upper body is advantageous if the individual grid body having substantially the same dimensions. The invention is not limited to this embodiment. In principle, the individual grid bodies (of the same type as well as different types) can have different dimensions. Thus, the grid bodies of one type can have different dimensions in that, as in a modular system, grid bodies in a first dimension (main dimension) and various other grid bodies with dimensions that are for example half as large or one third as large or one quarter as large or have a different size proportion of the grid body with the main dimensions.

In a further advantageous embodiment of the invention, it is expedient that the lattice boxes are provided with a plurality of stackable grid plate intermediate elements each with a top and a bottom, each grid plate intermediate element having a grid strut and a plurality of in particular evenly distributed over the grid plate intermediate member arranged supporting parts which extend substantially transversely to the extent of the intermediate grid plate member from the underside thereof to the upper side thereof and supported on the support members of an adjacent intermediate grid plate member disposed below a respective intermediate grid plate member and supporting the support members of an adjacent intermediate grid plate member disposed above the respective intermediate grid plate members.

The above-described concept of the layer or plate structure of each grid box is based on the use of identical parts, namely the intermediate grid plate elements, which are arranged one above the other, so that the height of the grid box in its installed state is adaptable to the given spatial conditions. The weight forces acting on the stack of intermediate grid plate members are captured by the support members of the intermediate grid plate members against which adjacent intermediate grid plate members abut one another. This results in a modular system that meets the requirements of the load-bearing, as they are found in practice.

According to a development of the lattice box can be provided that the support members are strand-shaped and in particular designed as bolts and their opposite ends are provided with a connecting projection at one end and a connection receptacle at the other end, wherein adjacent support members or adjacent groups of support members their arranged at the top or bottom ends are alternately provided with connecting projections or connection receptacles and wherein adjacent intermediate plate plate members are interconnected by the connecting projections and receptacles under load-transmitting connection of their support members. This can also be provided with advantage that the at adjacent support members or support members of adjacent groups of support members arranged connection projections and connection receptacles of each intermediate plate intermediate plate are each provided alternately, so that a connection projection or a group of mutually adjacent arranged projections a group of mutually adjacently arranged connection receptacles follows.

In a further advantageous embodiment of the invention, it is provided that on the uppermost grid plate intermediate element of the stack, a grid plate lid member and / or below the bottom grid plate intermediate element of the stack, a grid plate bottom element is arranged, which are in particular identical and each a grid struts and one-sided protruding support members for connection to the support parts of have top and bottom tie plate intermediate element of the stack. The grid plate cover or grid plate floor element is, in particular, the upper or lower half of a grid plate intermediate element which is divided in terms of its extent. This can still be equipped with further bracing.

For the grid box installation as drainage or drainage and / or water storage body so several first intermediate plate elements are required, the stack of these elements can be completed by a grid plate cover element or a grid plate floor element. These last two elements are not absolutely necessary.

The modular system of the lattice box can advantageously be supplemented by a rinsing, inspection or connection channel lattice element which is integrated in the stack of intermediate lattice plate elements. This channel grid element has an upper surface on which a grid plate intermediate member rests and an underside resting on a grid plate intermediate element. The connection technique of the channel grid element to the respective adjacent grid plate intermediate elements is advantageously realized in the same way as the connection of adjacent grid plate intermediate elements. In other words, extending through the channel grid element in its thickness extension again supporting parts, which are preferably formed strand-shaped and in particular in the manner of rod sections or bolts.

Furthermore, it is possible and advantageous that a channel grid element is arranged between two adjacent grid plate intermediate elements of at least one grid box, the channel grid element having a top side and a bottom side, a grid strut having a flushing channel extending transversely to the thickness extension between the top and bottom sides and from the top side to the top Having the underside extending support members for connection to the support members of each disposed above or below the channel grid element grid plate intermediate element.

In an advantageous embodiment of a lattice box is provided that the channel lattice element has four identical Kanalgitterteilelemente, of which a first pair next to each other and a second pair is disposed on the first pair, each channel lattice member a grid strut having substantially transverse to its extension supporting parts and at one Edge having a substantially over a quarter of the cross section of the channel extending, provided with perforations channel inner side portion, wherein each two adjacent Kanalgitterteilelemente symmetrical to a stacking direction extending plane and two superposed Kanalgitterteilelemente are arranged symmetrically to a direction transverse to the stacking direction plane.

Alternatively, it can be provided that the channel grid element has two identical channel grid sub-elements, which are arranged side by side and symmetrical to a stacking plane, wherein each channel grid member element has a grid strut with extending substantially transversely to their extension support members and an edge, the one above in forms substantially half of the cross-section of the channel extending perforated inner side portion of the channel. In this embodiment, the channel plane consists of two identical channel grating sub-elements.

Overall, therefore, with the invention for the lattice box assembly, a modular system for assembling lattice boxes is provided which are each composed of at most three different elements, wherein the number of stacked intermediate lattice plate elements is selected depending on the size of the space to be filled by a lattice box ,

Another special feature of the grid box can be seen in the fact that the grid plate intermediate elements and, if present, the channel grid elements and their sub-elements have geometrically identical grid structures. This creates in the stacking direction extending passages in the lattice box by the lattice openings of all elements are each aligned with each other and thus form the lattice box in the stacking direction traversing passages. This is particularly advantageous for the treatment, storage and other processing of heavily polluted fluids ( for example, sewage treatment plants in which the installation can be used as a trickling filter or bioreactor (for example, as a dipped fixed bed)).

It should be emphasized at this point that the features of the device according to the invention can be combined according to claims 1 to 7 with the features of the device according to the invention according to claims 8 to 22.

The invention will be explained in more detail with reference to several embodiments and with reference to the drawings. In detail, they show:

1 shows in perspective a partial view of an apparatus for forming cavities in the ground below the surface of the earth for drainage and / or water storage purposes, wherein the device is passable at the level of the earth's surface. The device has overhead grid bodies 10 on, and at least one layer of such grid body 10 , wherein the at least one layer may be constructed of one or more types of grid body, which will be described later with reference to the 2 to 23 will be explained. The grid body 10 are plantable and form the navigable top of the device. Below the grid body 10 There are several side by side and possibly also stacked grid boxes 100 , which serve the water storage and together with the grid bodies 10 the payloads intercept. The grid boxes 100 are layered or slices constructed, which also below on the basis of 24 to 35 will be explained.

2 shows a perspective view of a first grid body 10 , which is made in this embodiment as an injection molding of plastic. The first grid body 10 has a bottom wall 12 on, along the edge of an upstanding, peripheral edge web 14 runs. The edge bridge 14 but can also only in partial areas of the circumference of the bottom wall 12 be educated. Furthermore, the first grid body 10 from the bottom wall 12 towering, intersecting lattice struts 16 . 18 on that with the edge bar 14 are connected. The overall geometric configuration of the first grid body is cuboid, wherein the bottom wall and the peripheral edge web define a total of a rectangular structure. The mutually parallel longer side edges may, for example, be twice as long as the likewise parallel shorter side edges. Other dimensional ratios are possible. The lattice structure of the intersecting lattice struts 16 and 18 is even. In this embodiment, the grid structure defines chambers arranged in a grid 20 whose bottom wall sections each have an opening 24 exhibit. The edge bridge 14 is per chamber 20 with a marginal ridge recess 22 Mistake. Furthermore, the lattice struts 16 . 18 Recesses or breakthroughs 26 on, as this in particular on the basis of 5 can be seen.

The height of the lattice struts 16 . 18 can be substantially equal to the height of the edge web 14 be.

In the 6 to 9 are different views of a second grid body 30 shown. Also the second grid body 30 has a lattice structure of intersecting lattice struts 32 . 34 on, by an upstanding, peripheral edge bar 36 are surrounded. The base area of the second grid body 30 is, as in the case of the first grid body 10 , rectangular, with the longer side edges being twice as long as the shorter side edges. The grid structure divides the from the peripheral edge web 36 defined area in a uniform grid of chambers open on both sides 38 passing through recesses or openings 40 are interconnected (see 9 ). Furthermore, the individual chambers 38 Edge web recesses 42 assigned. The height of the lattice struts 32 . 34 is substantially equal to the height of the edge web 36 (see before), but, as in the case of the first grid body 10 does not necessarily have to be like this.

The difference in the design of both grid body is therefore firstly that - unlike the first grid body 10 - the second grid body 30 the bottom wall is missing. In addition, the second grid body 30 with a plurality of substantially regularly arranged and distributed over the grid structure positioning protrusions 44 Mistake. These positioning projections 44 are at the lattice struts 32 . 34 arranged and protrude over one of the two main side surfaces (in the embodiment, for example, the lower main side surface) of the second grid body 30 out. They serve to position and fix the second grid body 30 on, for example, the first grid body 10 or another second grid body 30 ,

A grid body arrangement 50 from a first and a second grid body 10 respectively. 30 is exemplary in the 10 and 11 shown. This structure can be extended upwards as desired. An extension to the side is possible. For example, show the 12 to 18 more grid body arrangements 52 to 62 formed by differently oriented and arranged first and second grid body 10 . 30 are formed. It uses a so-called composite construction, as exemplified in 12 is shown. But it is also possible, the individual grid body as in 13 shown to arrange, so that within the arrangement cavities arise through which, for example, lines can be passed through.

In 19 is another embodiment of a grid body assembly 70 shown from a first grid body 10 as the lowest element and two arranged above second grid bodies 30 consists. Furthermore, the grid body arrangement 70 an L-shaped side wall element 72 on, in this embodiment, an outside of the arrangement 70 is covered. The L-shaped side wall element 72 has a vertically arranged in this embodiment wall plate 74 and a narrow wall plate extending at right angles thereto 76 on. The stiffening elements serve to stabilize this L structure 78 , By a wall element, as in 19 can be shown, the open on all sides of the arrangement 70 be closed on at least one side, so to speak. Depending on the nature of the environment of the installation, this may be necessary to prevent, for example, liquid seeped into the soil from coming into contact with, for example, areas to be protected.

The closer construction of the L-shaped side wall element 72 arises from the 20 to 22 , in which 20 a rear view (perspective) of the side wall element 72 and 21 a top view of the sidewall element 72 shows. 22 shows a front view of the side wall element 72 , In 20 are mechanical fasteners 80 at the back of the L-shaped wall element 72 shown. These fasteners 80 work with the edge ridge recesses 42 of the uppermost second grid body 30 together. The edge ridge recesses 42 are open to one side, leaving the second grid body 30 from above onto the projecting connecting elements 80 of the wall element 72 can be pushed. This results in a mechanical fixation of the side wall element 72 on the grid body assembly 70 ,

This type of fixation can also be used to grid body 10 respectively. 30 which are arranged side by side and define a layer of a multilayer grid body assembly to connect with each other. 23 shows a connecting element 90 which has the function of connecting two adjacent grid bodies. The connecting element 90 from below into some of the pairwise opposite marginal ridge recesses 42 two adjacent and laterally juxtaposed second grid body 30 pushed.

As already indicated above, the grid body should 10 shear-resistant or shear-stiff on the grid boxes 100 rest. This can be realized by positive connections, as described above for the connection of the two first and second grid body 10 . 30 are described. As a result, either the grid boxes protrude 100 or the grid plate lid elements 114 projections 102 upwards (see, for example 24 ) or from the bottom of the grid body 10 projections 104 (see, for example 4 ) down, which in corresponding, complementary receptacles or receiving wells 106 at the bottom of the grid body 10 (see, for example 3 ) or receiving wells 108 on top of the grid boxes 100 or the grid plate lid elements 114 intervene (see, for example 25 ). By this entanglement is a shear stiff connection, the "sliding" or "turning" the passable grid body 10 prevented when driving through a vehicle.

Furthermore, the openings 24 in the bottom wall 12 the grid body 10 or the open chambers 38 the grid body 30 with through holes 110 the grid boxes 100 aligned (in 24 indicated), so that you through these aligned openings and through holes from above through a grid body 10 respectively. 30 into the interior of a lattice box 100 arrives to be able to remove therefrom granules, for example by suction.

In the 24 and 25 are two drainage and / or drainage grid boxes 100 . 100 ' represented as used in the device according to the invention. Both grid boxes 100 . 100 ' have a plurality of superposed grid plate intermediate elements 112 on, which form a stack, the top and bottom of a grid plate lid element 114 or a grid plate floor element 116 is covered. The grid plate intermediate elements 112 are in the 26 to 29 shown in more detail, while the identical grid plate lid and floor elements in the 30 and 31 are shown in more detail.

According to the 26 to 29 has each intermediate grid plate element 112 a rectangular shape, in particular a square shape and is in this embodiment at right angles to each other in columns and rows extending grid struts 118 . 119 Mistake. At the crossing points of these grid struts 118 . 119 are support parts 120 , the like in this embodiment as a hollow bolt or the like. are formed. The support parts 120 extend from the top 122 a grid plate intermediate element 112 up to its bottom 124 , At one of its ends have the support parts 120 a connection projection 126 on, while the other end is open and a connection recording 128 for receiving a connection projection 126 forms. The orientation of the support parts 120 is between adjacent support parts 120 inversely or between adjacent groups of supporting parts 120 inverse to each other. In this way, adjacent grid plate intermediate elements can be 112 put together, with the support parts 120 adjacent grid plate intermediate elements 112 lie on one another and thus in the stacking direction of the grid box 100 respectively. 100 ' are load-bearing.

Also the grid plate lid elements and grid plate floor elements 114 . 116 are rectangular and square in particular and have next to running in columns and rows grid strut 118 . 119 further cross-lattice struts 130 on. As in particular by means of 31 can be seen, also have the Gitterplattendeckel- and bottom elements support parts 120 but survive only to one side of these elements. The other side (in 31 the top) is essentially free of jumps. This projection-free side forms either the top of the grid box 100 respectively. 100 ' or its bottom.

As based on 25 can be seen, the grid box 100 ' in an intermediate level 132 from a flushing channel 134 be traversed. The flushing channel 134 may be round or square in cross-section and extends transversely to the stacking direction of the grid box 100 ' , In the embodiment according to 25 becomes the flushing channel 134 of a total of four Spülkanalgitterteilelementen 136 formed, all identically shaped and according to 25 are arranged relative to each other. The Spülkanalgitterteilelemente are in the 32 to 34 shown in more detail and also have an intersecting, running along rows and columns grid strut 118 . 119 on, whose crossing points turn with supporting parts 120 are provided, as described above. In addition, each Spülkanalgitterteilelement 136 a border 138 on top of the inside section 140 of the flushing channel 134 forms over a quarter of its cross section. According to 25 in two superimposed planes in each case two of the Spülkanalgitterteilelemente 136 arranged symmetrically to a plane extending in the stacking direction, wherein the respective two Spülkanalgitterteilelemente 136 the two superimposed planes are in turn arranged symmetrically to a plane extending transversely to the stacking direction. The inside sections 140 on the edges 138 are with perforations 142 Mistake.

In 35 is an alternative trained Spülkanalgitterteilelement in side view 136 ' shown, which is a one-piece element of two superimposed Spülkanalgitterteilelemente 136 of the 32 to 34 represents.

Overall, therefore, a modular drainage and drainage drainage body is described for a drainage or drainage device, which is composed of a maximum of three different parts. The height of the body can be adapted to the given spatial conditions. By running in the stack direction adjacent support parts 120 all of the body forming grid plate elements creates a high load bearing in the stacking direction, which prevents the body from collapsing under the load of the soil above it (in the installed state). The entire body is expediently surrounded by a permeable covering material (for example fleece), which prevents the penetration of earth and rock or the like. Prevents soil components in the body.
