Abstract

A water retention system is assembled from modular components to fit the storage space available. Each module is made from two half shells linked onto connecting elements which provide the corners and which also enable the modular grid to be expanded. The connectors clip together and have profiled tags to clip into the edges of the modules. The modules are filled with a granular material and wrapped in a geo-textile.

Description

The invention relates to an infiltration system for construction a water storage and / or retention device with an infiltration module, the infiltration modules by means of appropriate connecting elements to a layer are connectable and this position by means of the same connecting elements are interconnectable.

Such a water storage and retention system is from Otto Graf GmbH as a so-called seepage block offered. These are box-like infiltration honeycombs, the one below the other horizontally and vertically by means of appropriate connecting elements to one closed water storage can be assembled. The individual honeycombs are possibly by means of corresponding channels connected. The combs point truss-like stiffened lattice walls and floor slabs, between which due to the numerous openings water taken in can circulate more or less freely. After building the arrangement in the desired height and The entire infiltration system will expand with one water permeable geotextile. such Water storage and retention systems are becoming targeted and controlled infiltration or accumulation of Rainwater used. For this, the corresponding retention devices constructed in modules, for example in Seepage area of a trough or a trough-trench system arranged, for example in connection with larger sealed areas, such as parking lots or roofs of Industrial plants used or even prescribed in some cases are. Such honeycomb elements offer the advantage compared to a significantly improved storage volume conventional gravel packs and drainage pipes.

The system explained above offers in particular the Advantage that with one and the same connecting element Infiltration modules in both horizontal and in vertical direction with each other to a closed Compound block can be assembled. The modules in A layer can only be used in one direction to be connected. In the case of a rectangular one Cross section of the modules, the modules are a layer either only in the area of their narrow sides or only in the area of their Long sides connected. A connection at each other outer edge of the respective module with its respective neighboring module does not exist. The network system appears to be in need of improvement.

Another problem with the connection of infiltration modules to form a closed network is that when using uniform connection elements the laying of the modules essentially only under Adherence to a predetermined uniform laying direction is possible. This means that the modules either from top to bottom to the neighboring one Infiltration module can be applied or in horizontal Direction until they match the respective Locking elements come into engagement. This requires on the one hand that the laying of the infiltration module does not is freely selectable depending on the local situation and the connection of the infiltration modules in generally only in the direction of installation along an imaginary vertical or horizontal line through the network. A cross connection to this connecting line generally does not exist or must also be introduced. The network can therefore for example due to subsequent or neighboring Earthworks shifted along these layers and in themselves be discarded

The known system also has the disadvantage that the Infiltration modules already as closed blocks are trained so that the storage and transport volume in Essentially the installation volume of the known infiltration modules equivalent.

The invention has for its object a percolation system to create a space-saving storage and transportation and its connecting elements if necessary, all outer walls of one at the same time Infiltration module with the outer walls of the adjacent Infiltration modules can connect, moreover, on site be assembled and assembled in a comfortable manner should.

The object underlying this invention is achieved with an infiltration system according to the characteristics of Main claim solved. Advantageous configurations result resulting from the dependent subclaims 2 to 19.

Because the infiltration module according to the invention at least essentially from two half-shell elements, that are composable, educated, do not have to complete infiltration modules stored and transported be, but only those on site Infiltration modules that can be assembled into half-shell elements. The half-shell elements are in a manner known per se designed stackable and thus allow a more compact Storage and a correspondingly compressed transport. The half-shell elements are then connected on site by means of corresponding fasteners opposite the prior art are improved so that they not just a connection of the infiltration modules with each other in the horizontal or vertical direction enable, but also the connection of the half-shell elements to the infiltration modules themselves.

For this purpose, the connecting elements are each with at least provide two differently designed locking elements, so basically two different laying directions get supported. Therefore, they can consist of two Infiltration modules composed of half-shell elements so that they can be put together at the same time four or at least two neighboring ones, each wall elements arranged orthogonally to one another are connected. The one from the infiltration modules The composite formed can thus be laid very flexibly and better braced overall.

The connecting elements are essentially double-sided open hollow bolt formed. The two-sided Openings again support the stackability and the Connection of the half-shell elements to one another.

The above-mentioned fasteners are on at least two opposite outer walls with each provided a locking element.

According to claims 4 and 5, it is differently designed locking elements, namely one Hook and an angle element. Depending on how the fasteners connected to the half-shell elements either one or the other Locking element for use. Both are connecting elements both a vertical and a horizontal laying direction can be used.

The half-shell elements as such comprise a base plate with four surrounding wall elements that are half-timbered are stiffened, and thus offer the necessary strength to build a water reservoir that can be driven on.

In an advantageous embodiment, at least the corners of the preferably quadrangular shaped half-shell elements as Square hollow profiles for at least sections positive reception of the connecting elements. Depending on how the fasteners in the Square hollow profiles are inserted, one gets or the other locking element is used. That in each case protruding on the outside beyond the half-shell element Locking element is used to connect with the adjacent one Infiltration module used. The inside in each case pointing locking element usually remains inoperative.

The connection can be additionally stiffened that the infiltration modules are not only in the area of Eckpunke but also by means of the length of the Wall elements distributed connecting elements be connected to each other. This is advantageous if more square hollow profiles in the wall elements, in over the length of the wall elements of the distributed arrangement are.

The infiltration modules are usually closed on site put together in a network. It has proven itself if the connecting elements with the half-shell elements be connected, each of which is a wall element assigned fasteners over the entire length this wall element can be used in the same direction, that this wall element on the outside along the entire length the same projecting locking elements is provided. At least one of the immediately adjacent, orthogonal running wall elements will then be advantageous equipped with the connecting elements in the area of this Wall element because each different locking element protrudes. This can alternate by moving horizontally and vertical insertion of a composite layer from above are created in which all infiltration modules connected to each other simultaneously via all wall elements are.

The connecting elements themselves have profiled Outer walls that are conical from top to bottom taper so that defined insertion depths of the Fasteners are given in the square hollow sections are.

In an advantageous further development, they are at least on the Square profiles in the corners of the infiltration modules open on both sides, so that the fasteners both from the open side of the half-shell element to build one closed infiltration module can be placed, as well on the open side of the respective half-shell element opposite side fasteners are used can.

In an advantageous embodiment, two half-shell elements can each on their open sides simply by doing so closed infiltration module are put together, that a half-shell element with its open side on one with connecting elements protruding from the top provided other half-shell element is attached.

In an alternative embodiment, a composite can consist of Half-shell elements also at least in sections like this be constructed so that the half-shells are in the same orientation be put together so that the open sides each from the bottom plate of the one above Half shell is covered. This creates a denser one Composite, as is required when the infiltration module considerable loads - for example, from being run over - is exposed.

The base plates of the half-shell elements are additional with stiffening ribs projecting towards the open side provided that nested like a grid are. This will further stiffen the Infiltration system reached.

In the area of the crossing points of the stiffening ribs formed lattice structure are either pipe sockets Connection of stiffening pipes and / or already finished molded pipe elements, their height or diameter varied as required, provided. The stiffening pipes serve to stiffen the closed infiltration module, especially with vertical force, such as him conceivable when driving over the infiltration modules is. By being partially finished in place of the molded pipe elements additional pipe sockets are provided, depending on the particular Load on site additional pipe elements in the Infiltration module introduced and thus the infiltration system optimally to the respective application adjusted and reinforced if necessary.

The stiffening pipes can be used for further power transfer Cross bars are added, which in corresponding cross slots inserted at the front of the stiffening tubes become.

In an advantageous embodiment, in the area of Crossing points of the stiffening ribs also other Square hollow profiles in the connection of further connecting elements be provided. This measure can also initially for stiffening, but also for connecting additional layers be used.

In a further advantageous embodiment, the base plate is provided with a cutting contour of lesser wall thickness. Because the smaller wall thickness is realized in this way is that the base plate in the area of this cutting contour jumps back on the outside relative to the rest of the base plate, is thereby a shoulder edge for cutting out a section, preferably a strip, from the Given base plate. As a result, for example Area of the infiltration module tunnels and channels be provided, such as for inspection of the infiltration module with corresponding remote-controlled surveillance robots are needed.

Due to the fact that there are recesses in the area of the base plate are provided, can be inside in this area Fasteners are pushed through, such as with the opposite bottom plate are connected. The corresponding connecting elements protruding from the base plate can in turn with a recess in the adjoining base plate are connected in such a way that thereby locking the adjacent layers is achieved.

The possible tunnel formation in the area explained above of the infiltration system is relieved that the wall plate with predetermined breaking and / or weak points for breaking out and / or cutting out defined wall elements are provided. This allows adjacent Wall elements are broken through in sections to create a Inspection channel or flow channel in the area of the to open seepage system according to the invention.

The entire infiltration system can be buried in the ground be introduced that it is either waterproof or a water-permeable covering is enclosed. In one case, the infiltration system for water storage, so used as a cistern in another case is a delayed, at least defined one Infiltration through the above-mentioned casing guaranteed.

The invention is described below using a Drawing only schematically illustrated embodiment explained in more detail.
