Description: The invention relates to a percolation module and to an underground infiltration system created therewith, as described in claims 1 and 13.

From EP 1 932 974 B1 a plastic infiltration module for creating an underground infiltration system has become known. This infiltration module comprises a main body of six mutually perpendicular, outer-level outer walls, which have at least partially water-permeable grid structures and an inner chamber. The main body forming the infiltration module is in the form of a cube, with continuous insertion openings being provided in each of the six outer walls relative to the inner chamber. In this case, the inner chamber is formed free of struts or support columns. The insertion openings have an opening size that is between 30% and 60% of the outer wall surface. Further insertion plates are provided with a Einsetzöffnungsgröße, which have at least partially a water-permeable grid structure and are used for selective insertion into selected insertion.

Another plastic infiltration block has become known from EP 1 607 535 B1. This also serves to form an underground structure for infiltration or damping purposes. This infiltration block has a substantially rectangular, cuboidal body with pairs of opposing first, second and third surfaces. Such a block is formed from two mutually identically designed component halves, which are assembled in a longitudinal separation plane. The two components have adjacent half-shell-shaped depressions, between which a web is formed. This web has transversely to its longitudinal extent additionally also a half-shell-shaped recess on. By assembling the two components of the rectangular block is created, which is then interspersed by two juxtaposed through holes, which can serve as an inspection channel. In the middle region of the web, a passage formed transversely to the passage openings is formed. In addition, closable openings can still be arranged in the continuous side walls, which allow access to the common passage opening of the two half-shell-shaped components. The outer walls are formed by a permeable grid structure.

The present invention has for its object to provide a percolation module and a composite therefrom infiltration system, which has a high intrinsic stability with low material costs and offers a high possibility of variation when assembling. In addition, the volume to be transported should be kept low.

This object of the invention is solved by the features of claim 1. The advantage resulting from the features of claim 1 lies in the fact that such a base body is created for a percolation module to which a connection of further infiltration modules is possible on all sides, and yet a stable and solid basic body can be formed. By providing the upper and lower chords and the web connecting the straps, sufficient space is created for forming and providing inspection openings or passage openings in combination with other infiltration modules and moreover a high combination possibility for creating extensive infiltration systems is created. This makes it possible to easily and inexpensively adapt infiltration systems to individual operating conditions without the need for special components. By appropriately assembling and combining such percolation modules, an individual design of a wide variety of infiltration systems can take place. In addition, however, a space-saving shape can also be achieved for the transport through the stackability of the individual infiltration modules.

Also advantageous is a further embodiment according to claim 2, as such a cube can be created 1/20 Austrian Patent Office AT 508 366 B1 2011-01-15 or cube-shaped body, which are easily adapted to different requirements depending on the installation position can.

A further advantage is an embodiment according to claim 3, as so on both sides of the body depending on the assembled, further infiltration module an inspection or. Passage opening can be created, this being possible with little space. The half-shell-shaped recesses thus serve not only the formation of the inspection or passage openings, but can also serve as a space-saving support surface during transport.

The embodiment according to claim 4, it is possible to reinforce the web forming lattice structure in addition, and thus to achieve a more stable training of the body. In addition, however, an improved drainage behavior of the liquid to be absorbed within the infiltration module can be achieved.

According to another embodiment variant according to claim 5, at least a partial passage through the boundary wall of the recess is achieved, so as to allow a fluid exchange between several modules.

Also advantageous is a development according to claim 6, since in the middle region of the web, an additional reinforcement and a stiffening associated therewith can be achieved.

In the embodiment according to claim 7 is advantageous that deposits can be prevented and the liquid can still communicate at least partially between several infiltration modules.

Through the development according to claim 8 ensures that a cross-connection between several inspection openings can be created. As a result, the receiving volume and storage volume of the infiltration module can additionally be increased.

Due to the construction according to claim 9, a columnar design of the web in the region of its front and back can be achieved.

According to one embodiment, as described in claim 10, while maintaining a large-volume Querströmvermögens still the overall strength of the body is not significantly reduced.

Also advantageous is an embodiment according to claim 11, since thereby the strength of the web can be improved despite the arrangement of the breakthrough.

In this case, an embodiment according to claim 12 proves advantageous, since it is also arranged with further arranged on the end faces of the web, further infiltration modules or cover plates a passage is achieved.

However, the object of the invention is independently achieved by the features of claim 13. The advantages resulting from the combination of features of this claim are that a complete, common passage opening can be delimited by the additional, further infiltration module, which is formed by a half component of the first percolation module, in combination with the first infiltration module. This takes place in the smallest space, wherein in combination with the first infiltration module a stable boundary of the common passage opening can be achieved. Half of the dimensions make it possible to design a modular system that allows for a high degree of variation and yet allows all-sided connection of further infiltration modules in any arrangement and direction.

But is also advantageous an embodiment according to claim 14, since so the inherent rigidity of the further infiltration module can be increased. As a result, high bearing forces can be transmitted despite the low cost of materials to form the further infiltration module. 2/20 Austrian Patent Office AT 508 366 B1 2011-01-15 According to claim 15, a smooth and not susceptible to the deposition of contaminants embodiment of the further infiltration module is created.

In the embodiment according to claim 16, a proper completion of the first infiltration module in the region of the ends of the upper and lower chord is created.

It is also possible an embodiment according to claim 17, because thereby the first infiltration module can be completed on both sides with a space short, further infiltration module and so a coherent block is created at infiltration modules.

The embodiment according to claim 18 allows any extension of the percolation module by identically designed, first infiltration modules, whereby the infiltration system in this direction in space can be extended as desired.

Advantageously, the embodiment according to claim 19, since so the mutually infiltration modules by the interaction of the cover with these modules an additional coupling can be created. By overstretching the cover of the two infiltration modules in the region of their abutting faces of the upper and lower chords so the cohesion between them can be achieved in a simple manner. This is further improved if the cover element of this superior positioning approaches are provided, which engage in positioning recordings of the infiltration modules.

But is also an advantage according to claim 20, since at least a partially covering the common passage opening is achieved by the cover and the permeable grid structure. As a result, for example, nonwovens or mats can be arranged at the top of the infiltration modules, without them being able to enter the passage opening.

According to an advantageous embodiment according to claim 21, the possibility is created to provide access to the passage opening to perform, for example, inspections can. In addition, it would also be possible to connect a pipe system to a discharge at the passage arranged in the cover element so as to be able to convey the medium to be absorbed in the infiltration system there.

Finally, however, is an embodiment as described in claim 22 possible, since so identically formed infiltration modules can be produced, in which case by the additional positioning only on the abutting outer walls a corresponding arrangement is provided to the individual infiltration modules on a to prevent one another from slipping or shifting. As a result, a high degree of variation can be achieved with a few components.

For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

Austrian Patent Office AT 508 366 B1 2011-01-15 [0035] FIG. 7 shows a partial section of a possible arrangement of percolation modules for a percolation system according to the invention, in a perspective view; 8 is a partial section of another possible arrangement of Versickerungsmo modules to a percolation system according to the invention, in perspective view; 9 shows a first possible embodiment of a covering element for a percolation system, in plan view; FIG. 10 shows the cover element according to FIG. 9, in a view; FIG. 11 shows a second possible embodiment of a covering element for a percolation system, in plan view; Fig. 12, the cover of FIG. 11, in view.

Introductoryly it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or identical component names, the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or the same component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and are to be transferred to the new situation mutatis mutandis when a change in position.

All information on ranges of values in the present description should be understood to include any and all portions thereof, e.g. is the statement 1 to 10 to be understood that all sub-areas, starting from the lower limit 1 and the upper limit 10 are included, ie. all subregions begin with a lower limit of 1 or greater and end at an upper limit of 10 or less, e.g. 1 to 1.7, or 3.2 to 8.1 or 5.5 to 10.

1 to 3, a first infiltration module 1 is shown, which comprises a base body 2 with six mutually arranged in pairs, outside planar outer walls 3 to 8. Here, the outer walls 3 and 4 form a first pair of outer walls and are arranged at the selected representation in Fig. 1 above and below. The second pair of outer walls 5 and 6 form a front or rear side of the main body 2. Finally, the third pair of outer walls 7 and 8 limits third outer walls, which thus bound the base body 2 laterally.

The main body 2 of the infiltration module 1 is preferably formed from a plastic material, wherein this can be produced in an injection molding process. Furthermore, it is shown here that at least some of the outer walls 3 to 8 in part have a liquid-permeable lattice structure 9 or are formed by them. As can further be seen from the illustration of FIG. 1, the base body 2 has a substantially cube-shaped - ie cube-shaped - spatial form in the region of its outer sides, in which side edges 10 to 12 of the individual outer walls 3 to 8 are of equal length to each other. Thus, here limit the two side edges 10, the first pair of the first outer walls 3 and 4 in the corner towards the third pair of third outer walls 7 and 8. The other side edges 11 also limit the first pair of outer walls 3 and 4, but in the corner Finally, the third side edges 12 bound the second pair of second outer walls 5 and 6 toward the third pair of third outer walls 7 and 8, respectively. 5, 6; 7, 8 each aligned parallel to each other and the individual pairs are additionally aligned with each other in the vertical direction and equal sides long edges 10 to 12, the base body 2 is formed in the form of a cube.

The main body 2 comprises here in the region of the pairwise opposite outer walls 3 and 4 each have a top flange 13 and a bottom flange 14 and a top and bottom flange 13, 14 interconnecting web 15. Here, the web 15 is consistently 4/20 Austrian Patent Office AT 508 366 B1 2011-01-15 formed between the upper and lower chord 13, 14. Furthermore, the web in the vertical direction with respect to the upper and lower chord 13, 14 bounding outer walls 3, 4 and continuously between the upper and lower chord 13, 14 frontally bounding second outer walls 5, 6 aligned. A plane of symmetry 16 is on the one hand in the vertical direction with respect to the first outer walls 3, 4 and on the other hand centrally between the third outer walls 7 and 8, which are arranged laterally with respect to the web 15, aligned. The web 15 is arranged centrally in its cross section with respect to the plane of symmetry 16 extending.

As can now be seen from a comparison of FIGS. 1 and 2, the main body 2 of the infiltration module 1 in a view of the second outer wall 5 has an approximately "Γ-shaped cross-section in a vertical plane to the plane of symmetry 16 , The two third side walls 7 and 8 are here only partially formed and form narrow end faces 17 to 20. The web 15 is defined in its cross section on both sides by a C-shaped boundary 21, 22. In this case, the two boundaries 21, 22 on the side facing away from each other to the web 15 laterally adjacent third outer walls 7, 8 are open. Ends 23, 24 of the boundaries 21, 22 affect the upper and lower chords 13, 14 on the mutually facing sides of the straps. Thus, the two boundaries 21, 22 each form a half-shell-shaped recess 25, 26 in the third outer walls 7, 8.

The web 15 each laterally defining boundary 21, 22 may be formed by a boundary wall 27, 28. In addition, in the boundary wall 27, 28 also these passing through recesses 29 may be arranged or provided. On the one hand to give the boundary wall 27, 28 and thus the web 15 sufficient strength and on the other hand to create the possibility that liquid can flow through the recesses 29, here are the recesses 29 in a top and bottom chord 13, 14 closer Arranged area. So that the individual recesses 29 can communicate with the lattice structure 9, at least some of the recesses 29 are in fluid communication with the lattice structure 9.

As now better seen from a synopsis of Figs. 1 and 3, in the web 15 in a vertical direction with respect to the longitudinal extent of the web 15 aligned breakthrough 30 is arranged, which passes through the web 15 entirely. Furthermore, here the breakthrough 30 has a longitudinal extent, which with respect to the upper and lower chord 13, 14 bounding the first outer walls 3, 4 is aligned parallel to these. Thus, the longitudinal extent or a longitudinal axis of the opening 30 in the vertical direction is aligned with the plane of symmetry 16. Further, the aperture 30 may have a cross-sectional area having a size in a range with a lower limit of 20% and an upper limit of 50% with respect to a complete area of an outer wall 3 to 8 of the main body 2. As a result, a transverse connection between the two half-shell-shaped recesses 25, 26 arranged in the third outer walls 7, 8 is created within the web 15. If this breakthrough 30 is provided, the web 15 is reduced in each case in the region of the second outer walls 5, 6 to a columnar design.

Furthermore, the opening 30 may also be circumferentially provided with a lining 31. In addition, it is also possible that these openings 32 passing through are still arranged in the lining 31 of the opening 30.

FIGS. 4 to 6 show a further embodiment of a further infiltration module 33, which may be independent of itself, wherein the same reference numerals or component designations are again used for the same parts as in the preceding FIGS. 1 to 3. In order to avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1 to 3 or reference.

The further infiltration module 33 shown here, in its spatial form, is designed as one half of the main body 2 of the first insurance module 1 with respect to its plane of symmetry 16. The main body 34 of the further insurance module 33 is also here by analogously to the previously described outer walls 3 to 8 here also in pairs, parallel to each other and at a distance from each other arranged first, second and third outer walls 35, 36; 37, 38; 39, 40 formed. The arrangement according to the representation in FIG. 6 has been selected analogously, as has already been done in the case of the first infiltration module 1.

The previously described plane of symmetry 16 is arranged here in FIG. 6 in the region of the third outer wall 39. In the area of the two first outer walls 35, 36, the main body 34 in turn has a top flange 41 and in the region of the other, first outer wall 36 the bottom flange 42. Between the upper flange 41 and the lower flange 42 extends in the region of the third outer wall 39, a web 43. In the region of the third outer wall 40 is a web 43 defining the C-shaped, further boundary 44 is provided, the further half-shell-shaped recess 45 in the third outer wall 40 forms here. The further boundary 44 or the depression 45 formed thereby can likewise be formed by a further boundary wall 46. In this embodiment shown here, the boundary wall 46 is continuous and thus formed without any recesses or openings.

The outer walls 35 to 40 described above may in turn comprise in regions or sections the lattice structure 9 described above or be formed by them. On the third outer wall 40 of the main body 34, analogous to the two end faces 19 and 20 of the first basic body 2, further end faces 47, 48 are formed here. The two end faces 47, 48 thus form the remaining, third outer wall 40.

FIG. 7 shows a partial section of a infiltration system 49, which is formed here from a first infiltration module 1 and a further infiltration module 33. Here, the further infiltration module 33 is attached to the first infiltration module 1 in such a way that the two half-shell-shaped recesses 25, 45 of the first and further infiltration modules 1, 33 form a common passage opening 50. To achieve this position, the two end faces 47, 48 of the further infiltration module 33 are arranged adjacent to the end faces 17, 18 of the first infiltration module 1. This forms a separation plane between the two infiltration modules 1.33.

In addition, however, it would also be possible, in the region of the third outer wall 8 of the first infiltration module 1 with their end faces 19, 20 another infiltration module 33 or even a similar design, first infiltration module 1 adjacent to arrange.

Furthermore, it is also possible for at least one infiltration modules 1, 33, which jointly define at least one through opening 50, to cover at least one outer wall 3 to 8 or 35 to 40 at least one through opening 50, plate-shaped cover 51 is disposed adjacent thereto. The covering element 51 spans the parting plane between adjacent infiltration modules 1, 33 and can additionally serve for the mutual retention of the two infiltration modules 1, 33. The cover element 51 shown here in simplified form will be described in detail in the following figures. For holding the covering element 51 to the infiltration modules 1, 33, it is possible, for example, to provide latching projections 52 on the infiltration modules 1, 33 and of the protruding latching projections 53 on the covering element 51. In accordance with mutual arrangement and recess of the recesses 52 on the basic bodies 2, 34 of the two infiltration modules 1, 33 can thus be made a modular composition to the infiltration system 49.

Furthermore, it is shown in simplified form here that between these mutually immediately adjacent infiltration modules 1, 33 these mutually aligning positioning elements 54 can be arranged or provided. These are in intended for this purpose Positionieraufnahmen 55 of the two infiltration modules 1, 33 optional. This results in a mutual alignment and positioning of the individual infiltration modules 1, 6/20 Austrian Patent Office AT 508 366 B1 2011-01-15 33 for the formation of the infiltration system 49. Thus, a modular arrangement and arbitrary combining in a variety of ways possible. In the positioning receptacles 55 but also extensions of the cover 51 can be used so as to achieve a mutual centering between these components. The extensions of the cover 51 will be described later in detail.

FIG. 8 shows in simplified form a further arrangement possibility of different infiltration modules 1, 33 with respect to another infiltration system 49. In this case, the first row of the infiltration system 49 shown here above, starting from left to right, is formed by a further infiltration module 33, two first infiltration modules 1 and at the end, in turn, by a further infiltration module 33. Subsequently, a first infiltration module 1 and subsequently another infiltration module 33 are provided in the further row located below. The here formed in the first row, common through holes 50 are aligned here in the illustration in the vertical direction.

In the third row from the top, a single, further infiltration module 33 is provided, wherein here the orientation of the common passage opening 50 in the vertical direction with respect to the passage openings 50 takes place in the first row. Also in this area can be arranged on the outer walls 3 to 8 or 35 to 40 correspondingly formed cover 51.

FIGS. 9 and 10 show a possible embodiment of the cover element 51, which is possibly independent of itself, wherein the same reference numerals or component designations are used again for the same parts as in the preceding FIGS. 1 to 8. To avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1 to 8 or reference.

This covering element 51 formed from a grid structure 56 is adapted in its outline shape to the length of the side edges 10 to 12 of the base body 2 and has the same side length here. Thus, the cover 51 is seen in plan view square. The self-contained grid structure 56 forms a rust-shaped component, which can serve to cover the passage opening 50 described above. The otherwise plate-shaped lattice structure 56 has a constant fleas or strength, which is adapted to the loads to be removed therewith. For positioning the cover 51 on the infiltration module 1 or 33, this positioning lugs 57, which project beyond the grid structure 9 in the direction perpendicular to their strength. These positioning lugs 57 can be used in the previously described positioning receptacles 55. As a result, a rotation of the cover 51 relative to the infiltration modules 1, 33 is prevented. At the same time, however, a relatively good mutual support of directly abutting infiltration modules 1, 33 is achieved by the overstretching of both modules 1, 33. In order to prevent inadvertent lifting or detachment of the cover 51 from the infiltration modules 1, 33, here again the locking projection 53 is shown in closer detail, which likewise projects beyond the lattice structure 56 in the vertical direction. Again, several of these locking projections 53 are again provided and engage in the infiltration module 1, 33 attached position in the arranged there or provided recesses 52, as has already been described previously in FIG. 8.

The lattice structure 56 assigned to the passage opening 50 is here arranged eccentrically with respect to the center of the passage opening 50 in its internal construction. This results in an area to an increased arrangement of webs, wherein in the opposite region, the opening widths between the webs are chosen to be larger.

FIGS. 11 and 12 show a further embodiment of the cover element 51, which is possibly independent of itself, wherein the same reference numerals or component designations are again used for the same parts as in the preceding FIGS. 1 to 10. To avoid unnecessary repetition, reference is made to the detailed description in the preceding Figs. 1 to 10 or reference. Again, this covering element 51 shown here is again formed by a lattice structure 56 permeable to the infiltration modules 1, 33. Likewise, the locking projections 53 and positioning lugs 57 described above are also provided. In contrast to the cover element 51 described above, this cover element 51 shown here has a central passage 58 which is freely formed by any grid structure and leads into the passage opening 50. Depending on the choice of the size of the passage 58, this can also serve as an inspection opening, for example.

As can now be seen better from FIG. 12, an annular projection 59 defining the passage 58 projects beyond the grid structure 56 onto the side facing away from the positioning lugs 57. Thus, this approach 59 projects beyond the covering element 51 to the side facing away from the infiltration modules 1, 33.

Seen in plan view, this cover 51 may again have the same side edge length, as previously described for the length of the side edges 10 to 12 of the infiltration module 1.

For the sake of order, it should finally be pointed out that in order to better understand the structure of the infiltration module 1, 33 or of the infiltration system 49 formed therefrom, these or their components have been shown partially unevenly and / or enlarged and / or reduced in size.

The task underlying the independent inventive solutions can be taken from the description.
