Description

The invention relates to a drainage system, a method for producing the drainage system and components for forming the drainage system.

Rainwater infiltration systems are becoming increasingly important because there is a need to supply water to the floor on sealed surfaces such as roofs or concreted or paved open spaces to ensure orderly percolation without soil erosion.

Such infiltration devices can be created for example in the form of gravel pits or gravel channels. However, it has recently become more and more prevalent to form such infiltration devices also called box-like trenches in the ground, wherein individual components are used, which overall create a large cavity. In particular, such rigs are assembled from plastic lattice boxes, wherein plastic lattice boxes enclose a large cavity and at the same time can be flowed through well. In addition, such plastic lattice boxes are formed so stable that a plurality of these plastic lattice boxes can be stacked on top of each other and possibly even of vehicles is drivable. Such lattice boxes stack to serve as a rigole additionally wrapped with a so-called geotextile, which allows infiltrating the water from the trench into the surrounding soil. The rig also serves as a collecting container, which slowly releases accumulating rainwater.

Such systems are known in the art.

From the EP 1 416 099 B1 For example, there is known a drainage cell for a groundwater handling system having a housing defined by perforated boundary walls, a perforate base and an open top with a plurality of individual upstanding connector elements going up from the base toward the open top and connecting means comprise, which are designed for connection of two cell housings, which are arranged in use with their open tops substantially parallel. The connecting means in this case has a separate device, which is designed for an intermediate circuit between two cell cases whose open top opposite. The separate device in this case has a grid which defines a plurality of individual inner or outer connecting means, which are designed for connection to a respective outer or inner connector element of a cell housing.

From the EP 1 452 653 B1 a seepage system is known, which serves to build a water storage and / or retention device of connectable infiltration modules and corresponding connecting elements. The infiltration modules can be connected to one another by means of connecting elements and the layers can be connected to one another by means of the same connecting elements. Here, the infiltration modules consist of two at least substantially identically manufactured half-shell elements which are composable, wherein the half-shell elements as such by means of the same connecting elements releasably connectable to the infiltration modules and composable and this connecting element is provided with at least two differently shaped locking elements, wherein in the assembled state a locking element when properly assembled a Laying in the vertical direction and the other locking element determines a simultaneous installation in the horizontal direction and limited.

From the DE 202 21 567 U1 a trench unit is known, which is formed substantially as a hollow body and has a base wall and a plurality of connecting walls which protrude from the base wall. A portion of this wall is permeable to liquid, the walls defining a fluid receiving volume and a channel extending substantially parallel to the base wall extending over a major portion of the trench unit and being open at both longitudinal ends thereof. This channel is intended to be designed as an inspection channel by stiffening or stabilizing ribs are provided below a base surface of the channel and / or a small portion of the total area of the base surface of the channel is pierced by openings and / or it is bounded by at least two connecting walls which at least partially are formed as a grid structure. In practice, such trench units show two box bodies separated by a channel, which are each framed by perforated walls, wherein between the box bodies the channel bottom is formed as a roadway for an inspection device.

From the DE 101 23 754 is a trench assembly with one or more trench components known to a rig pool, can be assembled, wherein the trench components are formed as a water-absorbing body and at least one of these water-absorbing body has continuous water pipes and the continuous water conduit has openings through which water can enter into the water-absorbing body of the trench component.

From the DE 298 23 806 a seepage device is also known, which is constructed in segments, wherein the segments are plastic lattice packings and the individual layers of plastic lattice packs consist of module-assembled lattice elements, the individual layers are secured against relative displacement among themselves by means of corresponding connecting elements.

From the WO 02/14608 A1 a structural component is known, which is also designed in the manner of plastic mesh boxes, wherein the elements are each similarly formed so that they can be plugged with their open sides on each other and thereby form a closed box. The boxes can be attached to each other with dovetail connectors.

The object of the invention is to provide a drainage system, which can be produced inexpensively, is modular and which is flexible in terms of its structure.

The object is achieved with a drainage system having the features of claim 1.

It is also an object to provide a method for building the drainage system, which is simple, safe and yet flexible to carry out.

The object is achieved by a method having the features of claim 9.

In addition, it is an object to provide components for the drainage system for use in the process.

The object is achieved with components having the features of claim 12. Advantageous developments are characterized in the dependent subclaims.

The drainage system according to the invention is formed from components, wherein the components are generally open at the bottom boxes that have a top wall, two side walls and two end walls and, for example, have a square or rectangular base. The bottom wall and the side wall and the end walls are in this case formed with openwork fields, for example in a grid or honeycomb pattern, which are integrally limited by columns of a solid material. Within the space enclosed by the ceiling wall and the floor and the end walls cavity preferably extending over the height of the side or end walls support columns that project from the top wall to the open side. The fact that the side and end walls are formed more or less similar and also the top wall is formed with similar perforated fields, a very simple and inexpensive construction is achieved in addition achieves high flexibility.

In a square structure, for example, the side walls have three grids, which are bounded by the corner pillars and two side columns, the end walls are formed similar.

In addition, according to the invention, a base plate element is used, wherein the base plate elements are connectable to one another to form a large base plate to which the downwardly open box-like elements are connected by means of click-latching connections. Here, both the base plate elements and the attached boxes with each adjacent elements or adjacent boxes by means of simple connectors are connected to each other. In an advantageous embodiment, at least in two opposite side walls or end walls in each case opposite a recess or a grid compartment released.

The embodiment of a component in which at least one central compartment is kept free at the front side differs from an embodiment of the component in which it is enclosed on all sides with compartments in that two components with the areas of the side compartments can be stacked by the free central compartment. In this respect, this can reduce the stack volume. After the stacked for transport components are separated from each other, the open Gefach can be closed with an appropriate closure device before laying or after laying, so that even a closed all-round component or a hollow body closed on all sides (after laying) is achieved.

In order to achieve a staggered stacking and thus a higher stability, additional elements can be provided which in particular have 1/3 of the width of a previously described element, but otherwise are constructed identically. This can be analogous to a stonewall masonry offset in the edge area use third elements in the next stack level are covered by a full element, so that a stability increasing offset comes about. According to the invention, it is possible to leave 1/3 empty space between the individual elements, ie also the third elements, which is then bridged by other elements in the next stack level. As a result, passages are created between the components to rinse, for example, the trench.

In the invention it is advantageous that a drainage system with a very high variability is created, whereby also different components can be combined with each other and so a maximum flexibility can be achieved both in terms of stability and spatial extent, but also what the Pressure resistance in sub-areas concerns. In particular, can be achieved by appropriate arrangement of third elements in a staggered walling a very high compressive strength, so that areas can be created which z. B. can be traveled on the surface with motor vehicles.

A component 1, 1a (FIG. Fig. 1 ) is a downwardly open grid box 1 with, for example, a square or rectangular base, wherein the component 1a has a top wall 2 and from the top wall 2 at the outer longitudinal edges 2a two opposite side walls 3 and two orthogonal arranged to these end walls 4 are present.

The top wall 2 has an opening pattern, wherein the openings 5 are, for example, square or rectangular apertures 5, which pass through the top wall 2 from its top 6 or outside 6 to its bottom 7 and 7 inside. These recesses 5 are arranged, for example, along the longitudinal edges in three groups, wherein in each case a group of four by four openings is arranged in the corners, each defining a group with four times nine openings 5 between them. Webs 8 are arranged between the groups, wherein the webs 8 extend from one side edge of the top wall 2 to the opposite edge, so that a total of four webs are formed, which meet at four crossing points, wherein a central recess field is formed by the webs 8 with for example seven times nine recesses 5.

The webs 8 are in contrast to the opening pattern, for example, fully formed or formed as a hollow body, wherein for venting or manufacturing reasons, the webs 8 may have at the top of the top wall openings 8a.

From the starting points of the webs 8 in the crossing points of the webs 8 and in the corners of the top wall 2, hollow columns 10, 11 extend downwards. As a result, four inner columns 10 and twelve outer columns 11 are formed. The outer columns are part of the side walls 3 and the end walls 4, wherein the side walls 3 and the end walls 4 each have a corner column 11a together and the corner columns 11a of each wall 3, 4 have two side columns 11b between them.

The columns 11 of the side walls 3 are connected to webs 14 in the region of their free ends 15, so that the webs 14 and the columns 11 of the side wall 3 and the longitudinal edge 16 of the top wall 2 define three compartments between them.

The corner pillars 11a and the side pillars 11b define a side pocket 17a between them, the side pillars 11b define between them a middle pocket 17b. Of course, this is to be understood only as an example, depending on the length and / or width of the component 1 may instead of a plurality of intermediate levels 17b and thus more than two side columns 11b be present. The number of center pillars 11 and the webs 8 increases accordingly and corresponds in particular to the number of side pillars 11b. The side folds 17a have a width a and the middle fold 17b have a width b. The width a extends from the outer edge of the associated corner pillar 11a to the transverse center of the following side pillar 11b. The width b of the median fold extends from the transverse center of one side pillar 11b to the next side pillar 11b.

Between the cavities formed by the columns 11, 11b in the top wall 2 insertion openings 12 are formed in the top wall 2, wherein the insertion openings 12 are square or rectangular, for example in cross section and be delimited by the outer longitudinal edge 2a or a narrow web formed by the outer longitudinal edge 2a. In the outer narrow longitudinal edge 2a may be present in the region of the opening 12, a small step. The openings 12 serve to receive connecting elements ( Fig. 6 . Fig. 8 ).

The compartments 17 have a height h, which corresponds to the height of the side wall 3 or end wall 4, wherein the height h extends from the outer longitudinal edge 2a of the top wall 2 to the lowermost or outermost side edge 14a of the webs 14.

These definitions apply equally to the side walls 3 as well as to the end walls 4.

The widths a and b may be the same, so that in three compartments 17, a third of the respective side or end wall 3, 4 takes place through the compartments 17. However, the widths a and b can also differ from each other. The compartments are filled with a honeycomb or grid pattern of webs 19.

In the area of the end faces 4, webs 14 are arranged only from the corner pillars 11a to the next side pillar 11b, so that no middle pocket 17b is formed.

The columns 10, 11 protrude beyond the webs 14 with free ends 15, wherein the free ends 15 are formed tapered so that when stacking two components 1 on each other, the tapered ends 15 in the hollow columns 11 of an underlying device 1 in Essentially form-fitting inserted. In order to bring about a connection, the columns 10, 11 have in the region of the top wall 2 recesses 20 which are, for example, square or rectangular. The recesses 20 are in this case a small distance from the outer longitudinal edge 2a, the corner columns 11a to depending on an outer side each have a recess 20 and thus two recesses 20 and the side columns 11b in the region of the side wall 3, 4 depending outwardly facing recess 20. The central columns 10 may be formed without recess or optionally one, two, three or have four recesses 20.

At the free ends 15 of the columns 10, 11 are corresponding resilient latching hooks 21 (FIG. Fig. 17 ), which are pressed by the insertion of the column 10, 11 in the underlying column 10, 11 first inwardly and snap on reaching the recess 20 to the outside and engage behind the manner of a locking element in the underlying column so that a solid , locking connection is ensured.

In this embodiment of the component 1a, it is advantageous that the components 1a can be transported stacked through the free central compartment 17b of the end faces 4a, in particular without the risk that the components 1a accidentally engage with one another. In order nevertheless to achieve a box closed on all sides closure elements 30 are provided.

These closure elements 30 are plate-like formed with a base plate 31, wherein the base plate 31 has a width which corresponds approximately to the width b, and has a height which corresponds approximately to the height h or is slightly lower.

From the base plate 31 extends to one side an inner frame 32, wherein the inner frame 32 is formed so that it on the one hand approximately encloses the surface of a middle shelf 17b and on the other hand is formed so that it substantially positively against the side pillars 11b and an outer one Longitudinal edge 2a rests. The area enclosed by the inner frame 32 is formed perforated in the plate 31, so that it can be flowed through.

The openings may be designed so that, starting from a transversely but with respect to the height displaced from the middle tubular member 33 circular elements are arranged, wherein a first circular member 34 is concentrically disposed about the tubular member and tangentially to the nearest side of the frame 32 is present. Two respective larger circular ridges are disposed around the circular ridge 34, with a first circular ridge 35 eccentrically but also tangent to the same location as the circular ridge 34 adjacent the frame and a next larger eccentric circle disposed therearound ( Fig. 7 ). With these circles, which are spaced apart by ribs 37, pipe connections can be realized in order to set up flushing pipes.

On the inner frame 32 spaced apart locking elements 40 are arranged, wherein the locking elements 40 consist of plate-like elements 41 which protrude beyond the frame 32 of the plate 31 away. On the plate-like elements 41 outwardly facing latching hooks 42 are arranged. The distance between the latching hook on the one hand and the inner surface of the plate 31 on the other hand is dimensioned so that this corresponds approximately to the thickness of the side columns 11b.

In this way, the closure element 30 can be fitted accurately with the frame 32 between two side pillars 11b, whereby it passes behind the pillars 11b when inserted from the outside with the latching hooks 42 and the closure element is accordingly firmly connected to the component 1.

In a corresponding stack of components 1a ( Fig. 11 ) All openings are thus closed.

In a further advantageous embodiment of the component 1b (FIG. Fig. 2 ) all compartments 17a, 17b are present, wherein the compartments are filled with a honeycomb pattern, which is formed from webs 19.

Although a further advantageous embodiment of the device 1a is the same in terms of the length of the side walls, but with respect to the width, ie the length of the end walls, but a reduced width, in particular in the periphery of a Seitengefachs 17a, wherein the Seitengefach 17a in this case of two corner pillars 11a is limited. Incidentally, the same parts are provided with the same reference numerals. The end face in this case has a width which corresponds, for example, to a Gefach 17a, but added half the column width of a corner column 11a. This results in otherwise the same dimensions that the end wall 4 has dimensions that corresponds to about one third of the already described components 1a, 1b.

To create the drainage system 1 base plates 50 are provided in addition to the components. The base plates 50 correspond in their design a top wall 2, but instead of continuing columns only corresponding recesses are also present with the corresponding recesses, so that columns are inserted there. Here, the same components are provided with the same reference numerals. The base plate 50 has a base area corresponding to the base of a ceiling wall 2. Between a respective receptacle 51 for a corner pillar and a receptacle 52 for a side pillar 11b, a recess 53 is present directly adjacent to an outer edge 50a of the base plate 50, which, for example, in cross section is square or rectangular, and serves to receive connector elements.

In a further embodiment of the base plate, the base plate 60 is designed for narrow elements with, for example, one third of the end face, so that this base plate comprises about one third of the base plate 50. Otherwise, it is the same design, wherein the same components are provided with the same reference numerals.

The connecting elements ( Fig. 6 . 8th ) are designed so that they are non-positively inserted into the corresponding receptacles 53 of the base plates, but also the blocks, the connecting elements, if they are to connect adjacent base plates and components stacked thereon, consist of two columnar bodies 71, for example, Drehrund, from the inner contour forth the insertion openings 53 or z. B. octagonal are formed. These tubular bodies have approximately in the Axialmitte a connecting web 72 which connects the two tubular body 71 with each other and thereby forms a distance between the two tubular body 71 to each other, which is dimensioned so that the peripheral outer edge of the top wall 2 or the plates 50, 60 therebetween place has, which means that two of the circumferential edges must have space. In order to ensure the greatest possible stability of the connection, strip-like projections 73 may be arranged on the tubular bodies 71 such that they extend along the peripheral wall 74, wherein these are formed so that in a round tubular body 71 or for example an octagonal tubular body 71st these protrude into the outwardly facing corner regions of the insertion openings 43, so that the tubular bodies 71 are supported in the insertion openings 53 with at least three surfaces.

In an embodiment which merely connects the base plates 50, 60 together or connects together an uppermost layer of components 1, the tubular bodies 71 of the connectors 70 are formed only halfway, the connecting web forming a kind of base plate.

The method according to the invention for constructing a drainage system provides, for example, first of all laying base plates 50 and connectors 70 with a composite base plate which corresponds to the base area of the planned stack of components 1. After this base plate has been completed and possibly already placed on a Geovlies, first components 1 are placed accordingly on the base plate, the free ends 15 of the columns 10, 11 are inserted into the corresponding insertion openings 51, 52 and in the presence of corresponding locking elements 40 and corresponding latching openings 20 latch there and hold the component 1 firmly to the base plate ( Fig. 13 ). Subsequently, the components 1 are further stacked on each other in the same way until a desired space is stacked from the elements, wherein each of the components are connected to each other a layer and with the overlying layer with the corresponding connectors 70. Subsequently, the components 17b which are still accessible from the outside are closed with the elements 30 in the manner already described in the case of components with free center diameters 17b in the manner already described.

In a further advantageous embodiment of the method for creating the drainage system ( 15 to 19 ), the drainage system is formed of the wide building elements 1b, which are closed on all sides, and the narrow building elements 1c, so that an offset can be achieved in the manner of a brickwork. For this purpose ( Fig. 16 ) designed a base plate with plates 50 and 60 and connectors 70, wherein narrow base plates 60 and wide base plates 50 are laid alternately, wherein at one end of the planned base plate instead of an alternating laying two narrow plates 60 follow. Onto the two narrow plates 60 and one third of the wide plate 50 attached thereto, a wide component 1b is laid up and latched as already described. The next large component is placed with a Gefachabstand of the first component 1b away on the base plate and locked there and then also placed with a Gefachabstand a narrow component 1c on the base plate and locked, so that when using three components 1 two distances are met , The next layers ( Fig. 18 ) are placed accordingly offset, so that each space between the components 1b, 1c is then covered by a wide component. Of course, this type of stacking can also be extended significantly in terms of expansion over three components in width and is shown here only by way of example. After reaching the desired stack height ( Fig. 19 ) are also covered in order to cover the free spaces in the uppermost layer and to form a plane, the base plates 50, 60 from the top of the stack and connected to each other. The outwardly facing openings of the voids are closed with the cover elements 30, since they have the same dimensions as the missing partitions in the case of components without intermediate 17b.

Of course, the offsets and distances within the layers can be realized in both spatial directions (not shown).

In a further embodiment of the system ( FIGS. 20 to 24 ) are only narrow components 1 is used, the narrow components 1 are placed on a wide base plate 50 so that they terminate laterally and a distance of a Gefachbreite keep between them. The next narrow components are accordingly offset by 90 ° placed on the underlying components, also with the appropriate distance, so that in any case an offset and thus an increase in stability is accompanied.

After the stack has reached the desired height, a wide base plate is placed at the top. The outwardly facing openings of the spacings between the components 1 are subsequently closed with the cover elements 30.

In the case of the abovementioned system, it is advantageous that, when components with missing center diameters are used in the end faces, good stackability during transport is possible.

In particular, in the method of advantage that a system can be created in which fewer components are needed because they can be installed with distance from each other, which allows for a staggered walls and thus greater stability and on the other hand, the use of materials and thus reduces the weight of the drainage system and increases the water absorption capacity.

It is advantageous in the case of the components that they can be manufactured very simply and inexpensively by injection molding, have high stability and can be used very flexibly, in particular in conjunction with the base plates 50, 60. By the use of the cover 30 weight is also saved, since only the outer access to the interior, which is formed by the components, must be closed. Furthermore, the cover elements 30 are advantageously provided with hose connections, so that for optionally cleaning work can be done to flush the interior.

The invention thus comprises a drainage system for temporarily storing and discharging water into the ground, wherein base plates 50, 60 are designed to be designed according to a desired base area and components 1a, 1b, 1c are designed as downwardly open grid boxes with locking devices attached to the base plate and are latched, wherein the components 1a, 1b, 1c are laid in rows or at a distance to each other in rows and wherein a next layer of components 1a, 1b, 1c arranged such that the butt joint between components 1a, 1b, 1c of the lower Position and / or distances between the components 1a, 1b, 1c of the underlying layer are covered.

Furthermore, the invention relates to a drainage system, wherein the base plates 50, 60 and the components 1a, 1b, 1c have latching means, so that the components 1a, 1b, 1c, which are placed on the base plate 50, 60 on the base plate 50, 60th are latched and superimposed components 1a, 1b, 1c are locked together.

Furthermore, the invention is characterized in that the base plate 50, 60 and / or components 1a, 1b, 1c have first connection means and connecting elements 70 are provided with which side by side arranged base plates 50, 60 and / or components 1a, 1b, 1c connected to each other are.

Furthermore, the invention relates to a drainage system wherein the components 1a, 1b, 1c are arranged in both horizontal spatial directions within a position at a distance from each other, so that the overlying layer is formed offset in both directions.

According to the invention components (1c) are present to compensate for the offset, which have a width corresponding to the offset.

In addition, wide components 1a, 1b and narrow components 1c may be present to compensate for the offset, the distances between the components within the layers corresponding to the width of the narrow component 1c.

The invention further relates to a drainage system, wherein the cavities formed by arranging the components 1a, 1b, 1c at a distance from each other are covered to the outside with cover elements 30, wherein the cover elements 30 are clamped between two components limiting the cavity 1a, 1b, 1c , plugged in or arranged in any other way.
