Abstract

The invention presents a drainage body which has two substantially identically formed surface-area units, namely a base unit and a substantially identically formed cover unit, which can be connected to one another in an installed state via spacer elements. It is proposed to design the surface-area units such that they can be stacked in a substantially interengaging manner such that the spacing between the surface-area units in the installed state is substantially greater than the spacing therebetween in the stacked state, wherein the spacer elements are substantially in the form of a, for example, truncated cone or truncated pyramid with a circumscribed cross-sectional surface area which decreases as the spacing from the surface-area units increases. As an alternative to this, provision may be made for the spacer elements to be arranged on the surface-area units such that the base units and the cover units can be laid to overlap one another in the manner of a masonrywork assembly. This gives rise to a high level of stability with, at the same time, space-saving storage capability and transportation capability.

Description

trench body

description

The invention relates to a trench body according to the preamble of

Claim 1.

It should be mentioned at this point that the invention also relates to a rigging unit, which consists of a plurality of such trench body and in addition further, associated facilities.

Sealing surfaces significantly affects the groundwater balance. In addition, the draining surface or rainwater must be drained and fed to sewage treatment plants. To address this problem, infiltration devices are built, which consist of such Rigolenelementen. Such trench elements are known, for example, from the following publications: DE 20 2005 010 090 Ul; DE 202 21 567 U1; DE 10 2005 056 131 AI; EP 162 60 640 B1; DE 43 04 609 A1, EP 0 787 865 B1; EP 09 43 737 B1;

EP 1 416 099 B1; DE 697 00 174 T2; DE 299 24 050 Ul; EP 1 469 133 A2;

EP 1 887 145 A1; EP 1 452 653 B1. These known trench elements or

Leaching systems are only limitedly stable. In addition, there is a significant problem in terms of transportation and warehousing, as the

Trench units on the one hand should have the largest possible storage volume, but on the other hand just this increases the storage and stacking volume.

DE 201 05 694 Ul a water storage and restraint system is known, which is constructed of perforated shells with truncated pyramidally widening side walls. This ensures good stackability. However, the known system is then and only then suitable for receiving higher loads, if the individual elements are relatively small. In addition, it is not possible to build water-conducting units from several such water storage boxes. From EP 0 612 888 A1 it is known to use certain forms or casting devices for the construction of water drainage systems. However, the method described there is expensive and expensive.

The invention is based on the object, a trench body after

EP 1 452 653 B1 go on to form that high stability

is ensured.

This object is achieved by a trench body according to claim 1.

In particular, this object is achieved by a trench body, comprising at least two substantially identically shaped surface units, namely a bottom unit and a substantially identically shaped cover unit, which can be connected to one another via spacer elements at an installation distance, wherein the spacer elements are arranged on the surface units, that the

Ground units and the lid units overlap one another in the manner of a

Masonry Association can be laid.

This special shape of the spacers ensures that the surface units are considerably more stable to each other. This not only allows higher loads to be absorbed from the surface, but also allows for the construction of higher, larger volume of water (inter-) storage infiltration systems that are still stable.

Preferably, the spacer elements substantially one, z. B. truncated cone or truncated pyramid shape with a circumscribed

Have cross-sectional area, which is smaller as the distance from the area units.

It is particularly advantageous if a plurality of area units

interlocking is stackable. In addition, the design of the surface units such that the bottom and cover consist of the identical components, in turn, the storage and transport improves and reduces the cost of manufacturing.

The spacer elements are preferably formed as a hollow body with an inner cross-section which is so congruent to the outer cross-section, that the Spacers are stackable in one another. Thus, the spacer elements are not adjacent to one another during stacking, but rather into one another, so that larger groups of surface units form stable containers in themselves. Preferably, the

Spacers formed as a hollow body and together with the

Unit units formed in one piece.

The spacing elements preferably have plug / socket fixing sections distributed in such a way that they engage one another in the installed state. This causes a further increase in the stability of stacked surface elements. In this case, the surface units are stackable in such an intermeshing manner that the installation distance of the surface units is substantially greater than their spacing in the stacked state. Alternatively, the one, z. B. the socket fixing sections may be provided in the surface units, while the other fixation sections sit on the spacer elements.

The spacer elements preferably have locking devices for mutually locking the spacer elements together or for locking the spacer elements with the surface units in the installed state. As a result, each form a floor and a corresponding lid already stable units, which are thus built up to larger "raised floors".

The surface units further preferably have Ausbrechabschnitte for the formation of inspection openings, wherein preferably load distribution elements for

Placing and supporting a revision cover on the inspection opening are provided. In this way, even larger infiltration systems from time to time can be cleaned so that the infiltration preventing sludge and fines can be rinsed and sucked.

Due to their conical shape, the spacer elements already have a very high stability with regard to buckling and buckling. Preferably, nevertheless stiffening elements are attached to the spacer elements on their lateral surfaces, which further increase the stability. In particular, the outer surfaces are provided with beads which extend parallel to the longitudinal axes of the spacer elements.

Overall, then wave-shaped surface units, similar to one

As a result, a considerable increase in the stability of the spacer elements, in particular with respect to transverse forces, is achieved in a simple manner. Preferably, side walls are provided, which are designed such that they connect to each other at the bottom units and the cover units

are fastened. Thus, completely closed structures can be created all around except for water passage openings, which can be installed as a hollow body in the soil.

It is particularly advantageous if the side walls have side wall supports which engage with the spacer elements after connecting the side walls to the bottom units and the cover units for supporting the side walls. As a result, forces acting on the side walls are introduced into the spacer elements, so that a considerable stiffening of the side walls can be achieved via the already existing spacer elements.

The surface units preferably have in particular edge-side

Connecting means for horizontal and / or vertical connection with other surface units and / or for attaching side walls. These connection devices are preferably designed such that, for example, two surface units can be stacked on one another and connected to one another, so that systems of any desired height can be constructed. Furthermore, the surface units can be connected to each other horizontally, so that essentially arbitrarily large and arbitrarily shaped surfaces can be constructed. Finally, walls can be used at the edge, so that overall large volume

Hollow body arise. The wall elements can also be used for stabilization in the vertical direction.

The connecting devices are in this case preferably designed such that the surface units have projection-free edges. This ensures that the systems mentioned are constructed without gaps, which improves the stability of the systems.

The spacers may be provided as separate elements.

Preferably, however, the spacer elements are formed as a hollow body and formed integrally with the surface units. By this measure, a particularly cost-effective way is opened to produce the trench body made of plastic in per se known manufacturing process. Preferably, a plurality of additional elements is provided, with which the trench body can be constructed into rig systems. These include in particular cover elements, which are used to cover openings in the

Area units are provided. For example, these are openings in the area of the support elements designed as hollow bodies. Thus, if the spacers designed as hollow bodies have openings for the passage of water to be seeped, the cover elements provided for them are also provided with openings, so that the water to be seeped can also penetrate through these lids into the surrounding soil.

It is now possible to build individual, box-shaped trench body and assemble them via their peripheral connection means to larger units. An increased stability, however, results in particular when the floor and cover units are mounted in the association in the manner of a masonry association. For this purpose, the spacer elements and / or the plug fixing sections and the socket fixing sections are arranged on the surface units in such a way that the floor units and the cover units can be laid overlapping each other. It is possible to lay the individual units at an angle of 90 °. The advantages of such a type of laying correspond to those resulting from the construction of

Masonry are known. Such an arrangement results in particular if the following rules are observed: a) The arrangement of respectively identically formed fixing sections on one half of the surface unit is mirror-inverted with respect to a diagonal of this half of the surface unit; b) The arrangement of the fixing portions is relative to a first

Bisector of the area unit mirrored; c) With respect to a second area bisector of the unit area is the

Arrangement of the fixing sections inverted, so that at a

mirrored position is in each case the other fixing portion.

From the above, it is apparent that a rigging system is also claimed which comprises a plurality of trench bodies of the type described. This rigging system comprises ground units, with which cover units are connected overlapping each other in the manner of a masonry association. Preferred embodiments of the invention are explained in more detail below with reference to figures. Show here.

In the following description, the same reference numerals are used for the same and like parts.

1 to 6 is, so to speak, a "minimal element", which as a surface unit 10 has a lattice structure, of which protruding frustoconical spacer elements 20, 20 'are provided

Spacer elements 20, 20 'have differently shaped end portions. The spacer element 20 has a plug end section 21 and the spacer element 20 'has a socket end section 22. In this case, these end sections are dimensioned such that a plug end section 21 can be suitably inserted into a socket end section 22.

Furthermore, the spacer elements 20, 20 'have such congruent inner and

Outer cross sections on that they can be used together. Furthermore, the surface units 10 have edges 17, which are continuously formed in such a way that when the surface units 10 are placed next to one another they lie against each other substantially without gaps.

In order to connect the surface units 10 adjacent to each other, retaining grooves 41 are provided in the edge regions of the surface units, in which connection pins 42 (see FIG. 3) can be used. A connecting pin 42 thus sits in the assembled state of two adjoining surface units 10 in two adjoining retaining grooves 41. In order to be able to put two surface units 10 (in which case the spacer elements 20 protrude in opposite directions) are more connecting pin 42 (not shown in the figures) shown, which have only half the cross section of a connecting pin 42 shown here, so that the connecting pin then does not protrude beyond the edge 17 of the superimposed surface portions 10. If two such groups of superimposed surface units 10 are connected to one another on the full-side, connecting pins are provided for this purpose which have twice the height in relation to connecting pins which merely serve for "horizontal connection" of surface units 10.

In order to attach the side walls 15 (see FIG. 5), have the

Surface units 10 on the one hand edge grooves 16 and on the other hand insertion pin 44 which can be inserted into insertion openings 43 of the side walls 15. The edges of the side walls 15 are in this case shaped such that when a side wall 15 is connected to a surface unit 10, the side wall 15 does not protrude beyond the edge 17 of the surface unit 10.

In order to close openings 23, 23 '(see FIGS. 2 and 3), covers 35 (see FIG. 4) are provided.

The surface units shown in FIGS. 1 to 3, 5 and 6 are shown schematically again in FIGS. 7 to 10 in section (similar to FIG. 2). In this case, two surface units 10 are inserted into one another in FIG. The resulting height D _s , so the stack height, is only slightly larger than the height of a single

Area unit plus the height of the spacer elements 20, 20 '.

In order to fasten two surface units 10 to each other to form a trench body, a surface unit 10 is compared with the other surface unit 10th turned, so that the arrangement shown in Fig. 8 is formed. In this case, a spacer element 20, which has a plug end section 21 at its upper edge, faces a spacer element 20 'which has a socket end section 22. As is shown in FIG. 9, these end sections can be inserted into one another so that the surface units 10 then form a bottom unit 11 on the one hand and a cover unit 12 on the other hand. Here, on the one hand, teeth 24 and, on the other hand, notches 25 are provided in the plug end sections 21 and the socket end sections 22, which - as shown in FIG. 10 - engage in one another, so that the bottom unit 11 with the cover unit 12 via the spacer elements 20, 20 '. connected to each other. So it form two surface units 10 when they are connected to each other via the spacer elements 20 and the locking means 24, 25, already solid body whose stability in all

Directions is guaranteed. In this case, the installation distance D _{E is} considerably greater than the stack spacing D _s .

In Fig. 11 is shown how the different area units in the dressing

can be assembled. It will be seen from this figure that the cover units 12 are mounted offset therefrom to the floor units 11, so that the arrangement of three surface units 10, 10 ', 10 "shown on the right in FIG. 11 is connected to a single body which This can contribute to a considerable increase in the stability of such an overall arrangement.

The surface unit shown in Fig. 12 in a plan view similar to that of Fig. 1 differs from the surface unit described above first in that it is not a "minimum surface unit", but is composed of a total of four such surface units (one-piece).

Furthermore, in the area unit 10 of FIG. 12 to 14, a number of

Ausbrechabschnitten 13 are provided, which although on lattice as the rest

Surface unit 10 are covered, but from the surrounding material

can be broken out. Such openings serve as inspection access to the interior of the trench body. After such trench bodies are installed in the ground, so are covered with a layer of soil, are

Load distribution elements 30 provided on such broken

Ausbrechabschnitte 13 can be placed. These load distribution elements 30 have a cutaway pipe section 31 which at its upper end by means of a conventional (cast) lid (not shown) can be closed, so that a revision opening 34 is formed after removal of the lid. At the lower end of the load distribution element 30, support arms 32 are provided, which serve to transfer forces acting on the upper end (or on the attached cover) as extensively as possible onto the surface unit 10.

At this point it should be noted that the details described above, such. B. the connecting means 41 and 43, even in the embodiment of FIG. 12 to 14 should be present, but not shown for reasons of simplicity of illustration.

It can be seen from the above that with the surface units 10 presented here and their spacing elements 20, one can create any spaces and channels which are only closed at their outer contours by side walls 15 (see FIG. 5). If you want to increase the stability of the body thus created, so can be mounted in its interior side walls.

An assembly of several area units according to FIG. 12 is shown in FIG. On the left side of FIG. 15, a bottom unit 11 is shown, on the right a cover unit 12 is shown. When the lid unit 12 is folded on the floor unit 11, the plug fixing portions 21 are inserted into the socket fixing portions

Insert 22, resulting in a trench body, which is extremely stable by the assembly in the association without additional binding of the bottom unit 11 and the cover unit 12 forming surface units 10 in itself.

Various examples are now shown in FIGS. 16 to 19, such as

"Opposing" fixing devices, so the connector-fixing 21 and the socket fixing devices 22 are to be arranged, so on the one hand the

Surface units can form both bottom units and cover units, on the other hand, a mounting in the association can be done.

Hereinafter, another embodiment of the invention with reference to FIGS. 20 to

23 explained in more detail. Here, in these figures, each individual

Area units or trench bodies shown, which are constructed from individual unit areas. From the foregoing, however, it follows that such individual elements can be installed in conjunction with other individual elements to larger trench bodies. The surface units or trench bodies according to FIGS. 20 to 23 differ from the preceding embodiments first in that the

Spacer elements not smooth but with beads 26 and wavy

Lateral surfaces are equipped. This results in a significantly increased stability, especially against transverse loads and wrinkles or bumps.

The side walls have side wall supports 18, which in the mounted state (see FIGS. 22 and 23) effect a support of the side walls 15 on the spacer elements. Reference should also be made to FIGS. 8 and 9, which show in principle how such a support works. By this construction, a considerable increase in stability of the trench body and increase the resistance to lateral loads is ensured.

Furthermore, it can be seen from FIGS. 20 to 23 that the surface units 10 and side walls 15 are constructed as honeycomb bodies and thereby offer good water permeability on the one hand and high stability on the other hand. The

Surface units 10 and the side walls 15 finally have the above-described Ausbrechabschnitte 13, made through which connections of pipelines or inspection openings can be created.
