Description

Rigolensystem with at least one Versickerbox

The invention relates to a rigging system comprising at least one, in particular a plurality of percolation boxes which can be arranged in at least one horizontal position.

Such rigging systems are known in principle and serve for the retention, supply or storage of amounts of water below ground. In this case, plastic injection-molded percolation boxes are mostly used, which can consist of two or more identical, composite structural bodies having a three-dimensional and substantially hollow structure. In this way, using a relatively small amount of material creates a large catchment or Versickerraum underground.

Depending on the required size of the rigging system, the above percolating boxes are arranged one above the other in one or more horizontal layers and thus form an arbitrarily dimensionable box system. In order to prevent the ingress of earth and other impurities, the correspondingly arranged percolation boxes are surrounded in a known manner with a geo-fleece.

The Rigolensystem should be used under various circumstances. While applications are known in which the rig system is arranged relatively stress-free under a relatively thin layer of mother soil, it is also common practice to arrange rigging systems under frequently traveled asphalt surfaces, such as parking lots, which are subject to varying loading. This is not only a relatively high vertical stability and resilience of the Rigolensystems given, which is usually achieved by a corresponding design of the three-dimensional structures, but it is also a horizontal static load to consider. A rig system, which is subjected to different loads vertically, also experiences a variable horizontal load due to the load redistribution. Due to upcoming water pressure, this burden can also increase significantly. This can not only lead to a disadvantageous horizontal displacement of individual percolation boxes, but under unfavorable circumstances also to breaks in the structure, if this is not dimensioned sufficiently stable. However, if one were to use only percolation boxes which provide sufficient horizontal stability for all conceivable purposes, they would be oversized for a large part of the loads actually occurring and economically unviable.

The invention is therefore based on the object to provide a rig system, which has a higher, in particular variable depending on the purpose, horizontal stability in the Verbau- ungszustand.

To achieve this object, according to the invention, in a rig system having at least one, in particular several, in at least one horizontal position, in particular one above the other, disposable percolation boxes, the upper and lower sides of the percolation box have a profiling, in particular intermeshing, and the rigging system at least a reinforcing plate having a profiling on both sides, wherein the upper profile of the stiffening plate is designed to engage in the lower profiling of a percolation box and the lower profiling of the stiffening plate for engagement in the upper profile of a Versickerbox. In particular, it may be provided that the at least two percolating boxes are arranged in at least two horizontal layers and in the assembly position engages the respective profiling of the stiffening plate arranged between successive percolating boxes in the vertical direction in the profiling of the opposite sides of the percolating boxes.

The present invention thus allows for insufficient horizontal load capacity for the particular application, in addition to use at least one stiffening plate between the horizontal layers of percolation, which can absorb horizontal forces and significantly increases the overall stability of the trench system. There is little scope for the percolating boxes against each other or against the stiffening plate, particularly advantageously the stiffening plate between two percolating plates leads to their horizontal displacement-resistant arrangement. The possibility of not installing the reinforcing plates in the trench system or even using stiffening plates of different stability or loading capacity results in a variable horizontal stability of the entire rig system, which can be adapted with particular advantage to the particular application. In addition to increasing the horizontal load capacity of the rigging system thus also results in a variable adaptability, especially if stiffening plates of different stability / load capacity are available. Although in the following, the rigging system is usually described with a reinforcing plate inserted between two horizontal layers, it should be emphasized that advantages also arise, for example when only one horizontal layer is present and one reinforcing plate above and / or below the horizontal layer, which can incidentally also consist of a single percolation box.

As already mentioned, it is of particular advantage if the profilings of the upper or lower sides of the percolating boxes are also designed for mutual engagement with a non-provided stiffening plate. Then, a displacement of the percolating boxes in the horizontal direction against each other is effectively prevented solely by the superimposition of two Versickerboxen and the particular displacement-resistant engagement of their profiles. This engagement can be done suitably positive and / or non-positive.

With particular advantage, the underside of the stiffening plate can be profiled for at least partially positive and / or non-positive engagement in the profiling of a top of a Versickerbox and the top of the stiffening plate for at least partially positive and / or non-positive engagement in the profiling of a bottom of a Versickerbox. In this way, an excellent displacement resistance is given and horizontal forces can be absorbed by the reinforcing plate improved.

It should be noted at this point that while the profilings for certain applications may define a one-way resistance to displacement, it is particularly convenient and advantageous if the resistance to displacement is given in all horizontal directions.

The area of the stiffening plate may correspond to that of the top of a percolation box or a multiple thereof. It may be thought to adapt the stiffening plates for the particular application so that a single stiffening plate over the entire surface of the trench connects two horizontal layers of percolation. Of course, it is equally conceivable to use a plurality of stiffening plates between two layers, wherein a stiffening plate may in particular have the dimensions of the upper and lower sides of the percolation boxes. However, this does not mean that the stiffening plate must be arranged exactly between two superposed percolation, but it may be useful if the profiles are designed so that a stiffening plate can be arranged offset so that it also connects a plurality of horizontally adjacent percolation and additionally stabilizing effect. In this case, end pieces, ie stiffening plates whose area is smaller than the top of a percolator box, are provided with particular advantage, with which a complete arrangement of stiffening panels between two horizontal layers can be achieved despite staggered arrangement of stiffening panels.

The stiffening plate may consist of a plastic, in particular of polypropylene, which may for example still be fiber reinforced, in particular by glass fibers may be. For the production of the stiffening plate various methods are conceivable; so it can be injection molded or extruded. In addition, since it is a restraint system which serves to retain and / or infiltrate, the stiffening plates are at least partially permeable to fluid, in particular openings distributed over the surface of the stiffening plates can be provided for the passage of liquid.

As already discussed in the introduction, seepage boxes are known, which consist of two composite structural bodies, each having a three-dimensional, generally hollow structure. In this case, it may be provided, for example, that two similar structural elements, which are in particular substantially U-shaped in cross-section, are assembled mirror-symmetrically on a plane of composition so as to form the percolating box. In particular, it is also possible to form a central through-channel passing through the percolating box. The structural body can be made of injection-molded plastic, wherein the structure is formed so that the formed Versickerbox already has a certain stability in itself.

In such an embodiment, it may be provided with particular advantage that the upper side of the structural body provided for connection to another structural body for forming a percolating box has a profiling into which the profiling of the reinforcing plate in the assembly position, in particular at least partially positively and / or non-positively, intervenes. This embodiment makes it possible with particular advantage to form a stiffening plate as a kind of cover plate for an existing only half of the percolation, so a structural body, existing layers. To this end, the profiling of the structural body lying in the horizontal plane of assembly to form a percolating surface is in particular not only designed so that the stiffening plate can engage in it, in particular at least partially positively and / or non-positively, but it can also form the percolator box an engagement of the profile-side profilings of the structural bodies can be provided, which in particular is at least partially positive and / or non-positive.

Expediently, if the percolating boxes have at least one receptacle for these stabilizing elements passing through in the vertical direction, which stabilizing elements pass through a plurality of overflowing percolation boxes or overhang their top side, the stiffening panel has through openings and / or end receptacles for the stabilizing elements, in particular for positive and / or non-positive engagement , The percolating boxes thus comprise receptacles in which vertically extending stabilizing elements serving for vertical support are inserted. Such stabilizing elements may be, for example, bars, in particular profiled bars. They too thus form part of a variably adjustable rigging system, the stabilizing elements essentially having an influence on the vertical load capacity. However, both types of stabilization can advantageously be linked to one another by the at least one stiffening plate having through openings and / or end receptacles for the stabilizing elements, through which the stabilizing elements protrude, in particular at least partially positively and / or non-positively. Vertical and horizontal support elements are thus in direct contact and complement each other in their stabilizing effect in particular each other.

Conveniently, it can also be provided that the profiling of the bottom of the stiffening plate and in particular at least partially positive and / or non-positive engagement is formed in the top of a further stiffening plate. Then it is also possible to use several layers of reinforcing plates to further increase the horizontal load capacity. The stiffener plates are then simply stacked on top of each other before a new layer of percolator boxes (or, if appropriate, half percolator boxes) begins. Further advantages and details of the present invention will become apparent from the embodiments illustrated below and with reference to the drawings. Showing:

1 shows a schematic diagram of the arrangement of four percolation boxes 1 in the trench system 2 according to the invention. The percolation boxes consist of two structural bodies 3 made of injection-molded plastic with an open, three-dimensional and inherently stable structure which leaves open a through-channel 4. The two structural bodies 3 are center-symmetrically assembled on a plane of composition 5. Respectively on the top side and bottom side, the percolating boxes 1 have profilings 6, 7 which are obviously designed such that the top profiling 7 of a percolating box 1 can positively and non-positively engage in the underside profiling 7 of another percolating box 1, if these are horizontal as shown Layers are arranged one above the other.

In the present example, however, a stiffening plate 10 is arranged between the two layers 8, 9, which consists of an optionally glass-fiber reinforced plastic and also has an upper-side profiling 11 and a lower-side profiling 12 up. This is designed so that a simultaneous positive and non-positive engagement of the profiling 6 in the profiling 11 and the profiling 7 can be done in the profiling 12. In this way an improved horizontal stabilization is given.

It should already be noted at this point that the profilings, as illustrated in FIG. 1, are shown relatively coarsely for the sake of simplicity of illustration and, of course, may also be provided finer and in any desired configuration. In particular, the positive and non-positive engagement shown here is not absolutely necessary as long as a substantially displacement-resistant arrangement in the horizontal direction is achieved.

Although FIG. 1 shows only a section through the trench system 2, a profiling corresponding to the profilings 6, 7, 11, 12 is also given in the other horizontal direction, so that a displacement resistance is also realized in this regard.

A stiffening plate 10 may also be used as the lower end of the trench system 2 as shown in FIG. In this case, if necessary, additionally only one side profiled end plate 13 may be provided. It is also conceivable to arrange such a termination stiffening plate 13 directly at the lower end of the trench system as well as at the upper end of the trench system 2. In the state installed in the ground, the rigging system 2 is additionally surrounded by a geovlies not shown here.

It should already be noted at this point that the assembly surfaces of the structural bodies 3 located at the composition planes 5 also have an intermeshing profiling 14. FIG. 2 now shows in a three-dimensional view the essential structure of a stiffening plate 10. For simplicity, only the profiling 11 of the upper side is shown, which has a checkerboard-like pattern, wherein each offset square elevations 15 are provided which surround square depressions 16. Where in the profiling 11 a survey 15 is provided, a depression 16 is provided in the profiling 12 and vice versa. The profilings 6 and 7 are formed correspondingly offset, so that the positive and non-positive engagement is made possible. Of course, the embodiment shown here is only an example and various profiles are conceivable.

The size of the stiffening plates 10 can also be chosen differently, for example, they may have a multiple or just the area of the top of a Versickerbox 1. The stiffening plates can also be arranged offset to Versickerboxen 1.

Finally, it should be noted that the stiffening plate 10, as exemplified in only two of the depressions 16 and elevations 15, has passage openings 17 for liquids, that is at least partially liquid-permeable. It is expedient to arrange such openings 17 over the entire surface of the stiffening plate 10.

Obviously, the horizontal stability of the rigging system 2 can be varied. For example, the stiffening plates 10 may be at least partially omitted. On the other hand, it is conceivable to provide stiffening plates of different design, which can be used as needed. Any possibilities are conceivable.

In particular, it is also possible in the illustrated embodiment of the stiffening plate 10 to arrange a plurality of stiffening plates one above the other, in order to achieve a further horizontal stabilization, since the profiling 11 is also formed for positive and non-positive engagement in the profiling 12.

Finally, FIG. 3 shows a possibility of using the stiffening plate 10 as a cover plate for a layer of lower structural bodies 3. It is evident that the profiling 14 is likewise designed for positive and non-positive engagement in the profiling 12. FIG. 4 shows a percolating box 1. It comprises two identical structural bodies 3 which are combined to form a horizontal assembly plane 5, each having an open, three-dimensional and inherently stable structure. Both structural bodies 3 are substantially U-shaped and made of an injection-molded plastic, here polypropylene. As a result of the U-shaped design of the structural body 3, the essentially round through-passage 4 is centrally produced in the case of a mirror-symmetrical composition, as shown in FIG. 4.

The grid-like, apparent from grid elements, cross connections, struts, columns and the like composed three-dimensional structure is seen at least in sections fluid-permeable and substantially hollow, but still carried basically supporting. Possibilities for the specific embodiment of such structures are well known from the prior art and need not be detailed here. Apparently already forms the Versickerbox 1 alone a viable construct. To connect the two structural body 3 may be provided at 23 indicated insertion or latching elements.

As can be seen, the percolation box 1 now has ten receptacles 24 passing through both structural bodies 3, which extend in the vertical direction, that is to say perpendicularly to the plane of composition 5. These are, as will be explained in more detail later, formed for insertion of elongated stabilizing elements. The receptacles 24 can also be clearly seen in FIG. 5 best considered together with FIG. 4. By way of example, an inserted stabilizing element 18 in the form of a profile bar 25 is shown in FIG.

The receptacles 24 now have, as shown both in Fig. 4 and in Fig. 5, at its upper and lower end, the receptacle 24 horizontally penetrating locking elements 26 on which an inserted stabilizing element 18 can put on and is supported. As an alternative to the blocking elements 26, the receptacles 24 could also be provided with narrowing projections on which the underside of the stabilizing element 18 can also be placed. As a further support possibility for stabilizing elements 18, webs 27 to be recognized are provided in the longitudinal direction of the receptacles 24 in FIG. 5, which allow a clamping or pressing support of the stabilizing elements 18 in the receptacles 24. The webs 27 may, for example, have a thickness of three millimeters, while the wall of the stabilization element 18 may have a thickness of five millimeters, so that the webs 27 are held firmly around the stabilizing element 18 in the receptacle 24. As an alternative or in addition to the webs 27, it is also possible to provide a combination of snap-in nose and depression, which is not shown here in more detail, which allows the stabilizing element 18 to be held in the receptacles 24.

It may be provided that in some of the receptacles 24, the webs 27 (and thus also the receptacles 24 themselves) have a step 28. Such a step 28 may for example serve to receive a connecting element for connecting two adjacent percolation boxes in the trench system. Of course, 24 such a stage 28 may be provided in all recordings. A widening of the diameter of the receptacle 24 adjacent to the assembly plane 5 can also serve to position the stabilizing element 18 if this has a further diameter in the center.

As already explained, the percolation box 1 is inherently stable. However, there are applications in which a higher load of the percolation box 1 is to be expected, which can be made possible by the use of stabilizing elements 18. Stabilizing elements 18 need not be used in all of the receptacles 24, this can be made dependent on which load is to be expected. In addition, different stabilizing elements 18 may be provided which can accommodate different vertical forces.

An example is shown in the schematic diagram in FIG. 6, in which six stabilizing elements 18 in the form of profiled bars 25 are inserted into the percolating box 1. In each case lying in the corners recordings 24 and the two middle recordings 24 were occupied. By varying the number of stabilizing elements 18 and the type of stabilizing elements 18, the percolating box 1 can be adapted to a wide range of load capacity requirements. In general, it should be noted that the stabilizing elements 18 may consist of the same material as the structural bodies 3. However, another material is conceivable, in particular a harder material. In the present example, the profile bar 25 is made of glass fiber reinforced polypropylene.

As can be seen, the stabilizing elements 18 or profile bars 25 extend over the entire length between the blocking elements 26, are therefore substantially as long as the Versickerbox 1 is high. When assembling the percolator box 1, for example, first the rods 25 can be inserted into the lower structural body 3, whereupon the upper structural body 3 is placed. By the webs 27 and the locking elements 26 results in a very stable support, which can absorb particular shear forces between the structural bodies 3.

Fig. 7 shows in cross section the profile of the profiled bar 25. This comprises an outer tube 29 and an inner tube 30 and five radially extending connecting walls 31. Similarly, webs 32 can be seen, the clamping or pressing support of the profile bar 25 in the receptacle 24th support. By the inner profile, the Beulfestigkeit the profile bar 25 is increased, which further contributes to the stability of the Versickerbox 1.

As already mentioned, the stabilizing elements 18 can be designed to pass through the seepage boxes 1 arranged one above the other. In this case, a particular embodiment of the stiffening plate 10, as shown in Fig. 8 follows. Therein, the stiffening plate 10 has at least one through-opening 19 for stabilizing elements 18 penetrating it in the vertical direction. There is a positive connection.

Fig. 9 shows the case that the stabilizing elements 18 are formed only partially protruding. In this case, may be provided in the stiffening plate 10, a final reception 20, in which the stabilizing element 18 is received positively.

The types shown in FIGS. 8 and 9 thus have an interactive connection of vertical and horizontal stabilizing elements, which overall makes possible a higher stability of the total trigole system, which is variable in particular. It should finally be noted that the openings 17 shown in FIG. 2, which are provided there in each square partial profile, can of course be designed so that they act as an opening 17 for the passage of liquid on the one hand, but also as a passage opening 19 can serve for a stabilizing element 18 nen. In particular, a displacement of the stiffening plate 10 is then independent of the horizontal position of the stabilizing elements 18 given.

Finally, FIG. 10 shows, in principle, another possibility for a force-locking, clamp-connecting profiling, in which oval depressions 21 are provided in a stiffening plate 10 'into which rectangular elevations 22, in particular a little too large, are pressed in by the percolation boxes 1, so that a traction arises.
