Description

DESCRIPTION

Drain body

The invention relates to a drainage body according to the preamble of claim 1.

At this point it is already mentioned that the invention also relates to a drainage unit, which is made up of a plurality of drainage bodies of this type and additionally other devices, corresponding here.

Due to the sealing of surfaces, the management of groundwater is decisively impaired. In addition, the flowing surface or rainwater must be diverted and supplied to sewage treatment plants. To remedy this problem, filtration devices are built that consist of drainage elements of this type. Drainage elements of this type are known, for example, from the following documents: DE 202005010 090 U1; DE 20221 567 U1; DE 102005056 131 A1; EP 1260640 B1; DE 4304609 A1, EP 0787865 B1; EP 0943 737 B1; EP 1416099 B1; DE 69700 174 T2; DE 29924050 U1; EP 1469 133 A2; EP 1887 145 A1; EP 1452653 B1. These known drainage elements or filtration systems are only stable to a limited extent. In addition, there is a considerable problem in relation to transport and storage, since the drainage units must have, on the one hand, the largest possible accumulation volume, but on the other hand, this precisely increases the storage and stacking volume.

DE 201 05694 U1 discloses a water accumulator and a retention system, which is constructed from perforated covers with side walls that widen into the shape of a pyramid trunk. This ensures good stackability. However, the known system is suitable for the absorption of higher charges then and only then when the individual elements are relatively small. Furthermore, it is not possible to build water conducting units from several similar water accumulation boxes.

From EP 0612888 A1 it is known to use certain molds or pouring device for the construction of water diversion systems. However, the procedure described there is more expensive and expensive.

The invention has the aim of perfecting a drainage body according to EP 1416 099 A2, which constitutes the closest state of the art, so as to guarantee high stability, while improving transportability.

This objective is achieved by means of a drainage body according to claim 1.

Thanks to the special shape of the spacer elements it is guaranteed that the surface units are on top of each other considerably more stable. In this way, not only higher surface loads can be absorbed, but also higher filtration systems are created, which accumulate (temporarily) a greater volume of water and are still stable.

According to the invention, the spacer elements essentially have a cone-shaped or pyramid-shaped trunk design with a circumscribed cross-sectional area, which becomes smaller with increasing distance from the surface units.

It is especially advantageous when a plurality of surface units can be stacked by meshing with each other. Furthermore, by configuring the surface units so that the bottom and cover are made up of identical components, storage and transport are again improved and the cost of manufacturing is reduced.

The spacer elements are preferably configured as hollow bodies with an inner cross section that is consistent with the outer cross section, so that the spacer elements can be inserted into each other during stacking. The spacing elements thus do not rest next to each other, but each other, during stacking, so that the larger groups of surface units form stable packages. Preferably the spacer elements are configured as hollow bodies and are formed in one piece together with the surface units.

The spacer elements preferably have connector / socket sections distributed so that they mesh with each other in the assembled state. This causes a further increase in the stability of the surface elements stacked on each other. In this case the surface units can be stacked by meshing with each other, so that the mounting distance of the surface units is essentially greater than their distance in the stacked state. Alternatively the ones, for example the socket fixing sections can also be provided in the surface units, while the other fixing sections rest on the spacer elements.

The spacer elements preferably have interlocking devices for the reciprocal interlocking of the spacer elements with each other or for interlocking the spacer elements with the surface units in the assembled state. Thus, respectively a bottom and a cover Corresponding to it they already form stable units that can therefore be assembled into larger "double bottoms".

The surface units further preferably have removable sections for the formation of inspection openings, where the load distribution elements are preferably provided to place or support a inspection cover over the inspection opening. In this way, larger filtration systems can also be cleaned from time to time, so that sludge and fine substances that prevent filtration can be rinsed and vacuumed.

The spacer elements already have a very high stability with regard to dents and folds due to their conical shape. But preferably reinforcing elements are placed in the spacer elements on their wrapping surfaces, which further increase stability. In particular, the outer surfaces are equipped with grooves that run parallel to the longitudinal axes of the spacer elements. Altogether corrugated surface units are then produced, similar to a "flan shape". In this way, a considerable increase in the stability of the spacer elements in particular with respect to the transverse forces is obtained in a simple manner.

Preferably side walls are provided which are configured so that they can be fixed on the bottom units and the cover units by connecting them together. Therefore, with the exception of the water passage openings, completely closed packages can be created, which can be installed at the bottom as hollow bodies.

It is especially advantageous when the side walls have side wall supports that, after the connection of the side walls with the bottom units and the cover units for the support of the side walls, mesh with the spacer elements. In this way the forces acting on the side walls are introduced into the spacer elements, so that a considerable reinforcement of the side walls is obtained through the spacer elements that are otherwise present.

The surface units preferably have connection devices, in particular on the edge side, for horizontal and / or vertical connection with other surface units and / or for the placement of the side walls. These connection devices are preferably configured so that, for example, two surface units can be placed one on top of the other and connected together, so that the systems can be mounted at any height. Furthermore, the surface units can be connected to each other horizontally, so that essentially any size and any shape surfaces can be mounted. Finally, the walls can be inserted on the edge side, so that hollow bodies of large volume are produced as a whole. The wall elements can also be used for stabilization in the vertical direction.

The connection devices are preferably configured in this case so that the surface units have edges without protrusion. This ensures that the systems mentioned are built without gaps, which improves the stability of the systems.

The spacer elements can be provided as separate elements. However, preferably the spacer elements are configured as hollow bodies and are formed in one piece together with the surface units. This measure opens up a particularly economical possibility in the manufacture of the plastic drainage bodies in manufacturing processes known per se.

Preferably a plurality of additional elements are provided, with which the drainage elements can be constructed by forming drainage systems. Particularly to this belong cover elements, which are provided to cover the openings in the surface units. For example, these are openings in the area of the support elements configured as hollow bodies. When thus the spacer elements configured as hollow bodies have openings for the passage of water to be filtered, then the cover elements provided for these are also provided with openings, so that the water to be filtered can also penetrate through this cover to the bottom surrounding.

It is now possible to build individual box-shaped drainage bodies and assemble them through their connecting devices on the edge side into larger units. High stability occurs because the bottom and deck units are rigged in the manner of a masonry rig. For this purpose, the spacer elements and / or the connector fixing sections and the socket fixing sections are arranged on the surface units, so that the bottom units and the cover units can be laid overlapping each other. It is possible to lay the individual units at a 90 ° angle. The advantages of a similar type of laying correspond to those known for the construction of masonry. Such a provision occurs in particular after the following rules are observed:

a) the arrangement of fixing sections () respectively configured in the same way on one half of the surface unit is inverted specularly with respect to a diagonal of this half of the surface unit;

b) the arrangement of the fixing sections is mirrored with respect to a first surface bisector of the surface unit;

c) With respect to the second surface bisector of the surface unit, the arrangement of the fixing sections is inverted, so that the other fixing section is located respectively in a mirror-reflected position.

It follows from the above that a drainage system is also claimed, comprising a plurality of drainage bodies of the type described. This drainage system comprises the bottom units, with which the deck units are connected, overlapping each other in the manner of a masonry rig.

In the following description, the same references are used for the same pieces and with the same effect.

The surface unit shown in figs. 1 to 6 is, so to speak, a "minimum element" that has a grid structure as a surface unit 10, in which spacer elements 20, 20 'are provided, protruding in the form of a cone stem. These spacer elements 20, 20 'have different shaped end sections. The spacer element 20 has a connector end section 21 and the spacer element 20 'has a socket end section 22. These end sections are in this case dimensioned so that a connector end section 21 can be suitably inserted into an end section of bushing 22.

Furthermore, the spacer elements 20, 20 'have congruent inner and outer cross sections so that they can be inserted into each other.

Furthermore, the surface units 10 have edges 17 that are continuously shaped so that, by juxtaposing the surface units 10, they are in contact with each other essentially without interstices.

In order to be able to connect the surface units 10 to each other, clamping grooves 41 are provided in the edge areas of the surface units, into which connection pivots 42 can be inserted (see FIG. 3). A connecting pivot 42 thus rests in the assembled state of two contiguous surface units 10 in two contiguous clamping grooves 41. In order to be able to place two surface units 10 on top of each other (where the spacer elements 20 then penetrate in opposite directions to each other), other connection pivots 42 (not shown in the figures) are shown, which only have half the section cross section of a connection pivot 42 shown here so that the connection pivot does not then protrude from the edge 17 of the overlapping surface sections 10. If two similar groups of superimposed surface units 10 are to be connected to each other completely flat, then connection pivots are provided here that are twice as high as the connection pivots that only serve for the "horizontal connection" of the units surface 10.

In order to be able to position the side walls 15 (see fig. 5), the surface units 10 have, on the one hand, edge grooves 16 and, on the other hand, insertion pins 44, which can be inserted into the insertion openings 43 of the side walls 15. The edges of the side walls 15 are shaped in this case so that later, when a side wall 15 is connected to a surface unit 10, the side wall 15 does not protrude from the edge 17 of the unit surface 10.

In order to be able to close the openings 23, 23 '(see fig. 2 and 3) covers 35 (see fig. 4) are provided.

The surface units shown in figs. 1 to 3, 5 and 6 are schematically represented again in figs. 7 to 10 in section (similar to fig. 2). In this case in fig. 7 two surface units 10 are nested one another. The resulting height D ^s , that is, the stacking height is only relatively slightly greater than the height of an individual surface unit plus the height of the spacer elements 20, 20 ' .

To fix two surface units 10 together to form a drainage body, one surface unit 10 is rotated relative to the other surface unit 10, so that the arrangement shown in FIG. 8. In this case, thus, a spacer element 20, which has a connector end section 21 at its upper edge, is opposed to a spacer element 20 ', which has a socket end section 22. These end sections can be fitted together. - as shown in fig. 9 -

so that then the surface units 10 constitute, on the one hand, a bottom unit 11 and, on the other hand, a cover unit 12. In this case, the connector end sections 21 and the socket end sections 22 are provided, on the one hand, teeth 24 and, on the other hand, notches 25 which - as shown in FIG. 10 - mesh with each other, so that the bottom unit 11 is connected to each other with the cover unit 12 through the spacer elements 20, 20 '. Thus two surface units 10 already then form, when connected to each other through the spacer elements 20 and the locking devices 24, 25, solid bodies whose stability is guaranteed in all directions. In this case the mounting distance DE is considerably greater than the stacking distance D ^s .

In fig. 11 shows how the different surface units can be assembled in the rig. In this figure it can be seen that the cover units 12 are mounted offset from the bottom units

11 on them, so that the arrangement shown on the right in fig. 11 of three surface units 10, 10 ', 10' 'is connected forming a single body, which can be continued at will (extending to the left in fig. 11). This contributes to a considerable increase in the stability of such a global arrangement.

The surface unit shown in fig. 12 in a plan view similar to that according to FIG. 1 differs from the surface unit described above in the first place in that it is not a "minimum surface unit", but is constructed (in one piece) by altogether four such surface units.

Furthermore, in the surface unit 10 according to FIGS. 12 to 14 a series of removable sections 13 are provided, which are covered by grids as the remaining surface unit 10, however they can be removed from the surrounding material. Openings of this type serve as inspection ports into the drainage bodies. After drainage bodies of this type are installed in the soils, that is, they are covered with a layer of soil, load distribution elements 30 are provided that can be placed on the removable sections 13 extracted of this type. These load distribution elements 30 have a section of pipe 31 that can be cut off, which can be closed at its upper end by means of a usual (cast) cover (not shown), so that a revision opening 34 is formed after the cover removal. Support arms 32 are provided at the lower end of the load distribution element 30, which serve to transfer the forces acting on the upper end (or on the superimposed cover) on the largest possible surface on the surface unit 10.

At this point it is indicated that the details described above, thus p. ex. the connection devices 41 and 43 must also be present in the embodiment according to figs. 12 to 14, however, are not shown for the sake of simplicity of representation.

It follows from the above that with the surface units 10 presented here and their spacer elements 20 any spaces and channels can be created, which are only closed at their outer contours by the side walls 15 (see FIG. 5). If you want to increase the stability of the bodies thus created, then they can also be placed on their inner side walls.

A grouping of several surface units according to fig. 12 is shown in fig. 15. On the left side of fig. 15 a bottom unit 11 is shown, on the right a cover unit 12 is shown. If the cover unit 12 is raised above the bottom unit 11, so that the connector fixing sections 21 are inserted into the sections for fixing the bushing 22, thus a drainage body is produced, which is extremely stable in itself by rigging also without additional connection of the surface units 10 that form the bottom unit 11 and the cover unit 12.

In fig. 16 to 19 different examples are now shown, according to the arrangement of the "opposite" fixing devices, that is to say, the connector fixing devices 21 and the socket fixing devices 22, so that, on the one hand, the surface can be both bottom units and deck units and, on the other hand, it can be rigged.

Next, another embodiment of the drainage body is explained in more detail by means of FIGS. 20 to 23. In this case, these figures show respectively individual surface units or drainage bodies, which are constructed from individual surface units. However, from the above embodiments it follows that individual elements of this type can be used in construction in interconnection with other individual elements forming larger drainage bodies.

The surface units or drainage bodies according to figs. 20 to 23 differ from the previous embodiments in the first place in that the spacer elements are not provided with a smooth surface, but with grooves 26 or corrugated wrapping surfaces. This results in considerably increased stability, in particular against transverse loads and against folds or dents.

The side walls have side wall supports 18, which in the assembled state (see figs. 22 and 23) cause a support of the side walls 15 in the spacer elements. At this point, reference is also made to FIGS. 8 and 9, which show in principle how a support of this type works. Thanks to this construction, a considerable increase in stability of the drainage bodies and an increase in the resistance capacity with respect to lateral loads are guaranteed.

Furthermore, in figs. 20 to 23 it can be seen that the surface units 10 and the side walls 15 are constructed as a honeycomb body and thus, on the one hand, offer good water permeability and, on the other hand, high stability. The surface units 10 and the side walls 15 finally have the removable sections 13 already described above, through which the pipe connections can be made or inspection openings can be created.
