Description

[0001] The invention relates to a trench half element according to the preamble of claim 1.

[0002] In addition, the invention also relates to a trench component and a receiving, storage or infiltration device constructed from trench components.

[0003] Infiltration trenches, which serve to collect, store, or infiltrate fluids, especially rainwater, are assembled from individual elements. In particular, infiltration trench half-elements are used, which have a base grid, with columns rising approximately vertically from the base grid. Connecting devices are used to connect the infiltration trench half-elements at the tips of the columns, i.e., at the column ends opposite the base grid. The columns can either be loosely slotted onto one another or joined together using snap-in connections.

[0004] JP 2016-145500 A discloses a trench formed from trench half-elements comprising columns with an approximately octagonal cross-section, the columns carrying connecting means at their ends. The columns of two half-elements can be connected by means of these connecting means.

[0005] EP 2 862 982 A shows a trench consisting of trench half-elements, which have columns with recesses on their outer surface. The columns can be attached to a base grid in a force-locking manner. Congruent connecting elements are provided at the ends of each column. Two half-elements can be connected to form a trench by means of columns facing each other.

[0006] JP 2016-61112 A discloses a trench consisting of trench half-elements, wherein the columns are approximately round in cross-section and have recesses on their outer surface. Two half-elements can be connected to each other by connecting means at the ends of the columns.

[0007] JP 2011-226261 A also shows a trench consisting of trench half-elements, with the columns being approximately round in cross-section and having recesses on their outer surface. Two half-elements can be connected to each other by connecting means at the ends of the columns.

[0008] In order to arrange such infiltration half-elements in a space-saving manner during production, storage and transport, the columns are hollow so that such infiltration half-elements can be stacked by inserting the columns of an adjacent infiltration half-element into the hollow space of the columns of one infiltration half-element.

[0009] As part of a collection, storage, or infiltration system, the infiltration half-elements must withstand certain forces arising, on the one hand, from the underground installation of such a collection, storage, or infiltration system. This involves earth pressure and, if necessary, the hydrostatic pressure of the rainwater collected in them. On the other hand, they must also absorb traffic loads from the traffic routes above.

[0010] The columns of the infiltration half-elements serve to transmit the forces in the vertical direction. These must be designed according to the mechanical and static requirements.

[0011] When designing columns for a trench half-element with regard to the requirement for transmitting forces, there are always problems, especially if this type of column is also to be designed for the possibility of stacking the trench half-elements.

[0012] This is where the invention comes in, which has set itself the task of providing a trench half-element that overcomes the problems mentioned above.

[0013] A further object of the present invention is to provide a trench component.

[0014] Finally, it is also an object of the invention to provide a receiving, storage or infiltration device which is constructed from infiltration trench components.

[0015] The first problem is solved according to claim 1.

[0016] By ensuring that the wall of the column is equally inclined along its entire circumference relative to a normal that is perpendicular to the base grid, it is possible, on the one hand, to provide a very stable column for a trench half-element that can absorb and transmit forces, and, on the other hand, to ensure the stackability of the trench half-elements.

[0017] Within the scope of the present invention, such a trench half-element according to the invention can be designed in a particularly advantageous manner such that the inclination of the wall of the column along the entire circumference of the column relative to a normal which is perpendicular to the base grid is 2° to 8°, preferably 2° to 4°, over its entire length.

[0018] An inclination of the wall of the column along the entire circumference of the column relative to a normal that is perpendicular to the base grid, in the above-mentioned circumferences, is particularly favorable with regard to optimal force transmission of the column of the infiltration half-element and also the stackability of such infiltration half-elements.

[0019] It can be particularly advantageous in the infiltration half-element according to the present invention that the wall of the column is of the same thickness along the entire circumference of the column over its entire length.

[0020] By forming the wall of the column along the entire circumference of the column over its entire length in a uniform thickness, such a trench half element according to the invention can be produced in a simple and reproducible manner.

[0021] A molding process for polymer materials, such as injection molding, can be used as a manufacturing process. In an injection molding process, consistent wall thickness offers many advantages, particularly with regard to the cooling process and the prevention of sink marks and internal stresses in the component.

[0022] It may prove very advantageous in the present invention if the infiltration trench half-element is designed in such a way that the column has a cross-section over its entire length which is composed of curved sections and / or straight lines and / or corners.

[0023] A trench half element, in which the column has a cross-section composed of curved sections and / or straight lines and / or corners over its entire length, is easy to manufacture, has a high level of stability and is particularly designed to transmit forces.

[0024] This also ensures that such infiltration half-elements can be stacked.

[0025] In a particular development of the present invention, the column of the infiltration half-element can have an approximately square cross-section. Providing a square cross-section for a column of an infiltration half-element results in a uniform introduction of forces into the column, whereby the column can then also transmit these forces evenly.

[0026] Furthermore, the manufacture of a trench half-element with a column having an approximately square cross-section is particularly simple.

[0027] According to the invention, a recess is formed on each side of the column. In particular, it can be provided that, in the case of a column with an approximately square cross-section, such a recess is formed on all four sides of the column according to the invention. It is preferred if all four sides of the column have recesses of the same type and shape. Such a trench half-element is easy to manufacture. This also ensures that the trench half-element can be aligned with few or no restrictions during stacking.

[0028] By forming a recess on each side of the wall, this wall can be stabilized in a particularly advantageous way and thus transmit forces that are introduced into it.

[0029] The stackability of such infiltration half elements is also guaranteed.

[0030] In an advantageous embodiment, the column of the infiltration half-element can have at least one, preferably several, mirror planes. This measure results in a column of high symmetry that can absorb forces in a special way and transmit them along its length.

[0031] It may prove particularly advantageous in the present invention if the first connecting element and the second connecting element have a complementary shape, at least in sections, and if the first connecting element and the second connecting element can be plugged together. This makes it easy to form a single infiltration trench component from two infiltration trench half-elements by connecting the two infiltration trench half-elements.

[0032] It may prove particularly advantageous in the present invention if it is provided that the infiltration trench half-element consists of or contains a polymer material, wherein the polymer material is preferably a thermoplastic polymer material, in particular a polyolefin, such as a polyethylene, polypropylene, polybutylene or a copolymer of the aforementioned or a mixed composition of the aforementioned, or a polyvinyl chloride or a polyester or a polycarbonate.

[0033] The aforementioned polymer materials are easily moldable, stable, inert, durable, mechanically stable, resilient, and inexpensive to purchase. Infiltration trench half-elements can be easily formed from the aforementioned polymer materials. This can be accomplished, for example, through an injection molding process or another polymer processing and molding process.

[0034] Alternatively, it is also possible for the infiltration half-element to be manufactured using a generative manufacturing process, in particular in one piece, for example by a 3D printing process.

[0035] For this purpose, three-dimensional models that can be read by data processing machines can be used to advantage for production.

[0036] A method for generating a machine-readable three-dimensional model for use in a manufacturing process for a trench half-element is possible. In particular, the method also comprises inputting data representing a trench half-element into a data processing machine and using the data to represent a trench half-element as a three-dimensional model, wherein the three-dimensional model is suitable for use in the manufacture of a trench half-element.

[0037] The method also includes a technique in which the input data of one or more 3D scanners, which operate either in a contact or non-contact manner, the latter delivering energy to a trench half-element and receiving the reflected energy, and a virtual three-dimensional model of a trench half-element is generated using computer-aided design software.

[0038] The infiltration half-element can be manufactured entirely or partially using a line-by-line or layer-by-layer manufacturing process. In particular, the infiltration half-element can be manufactured entirely or partially line-by-line or layer-by-layer by material deposition.

[0039] A 3D data set can be used to great advantage during construction or production.

[0040] The solution to the further object of the present invention, to provide a trench component, is according to claim 7.

[0041] Within the scope of the present invention, it was recognized that a trench component is easily accessible if it is provided that two interconnected trench half-elements are connected to one another as described above.

[0042] Such infiltration trench components can in particular be formed from similarly shaped infiltration trench half-elements in such a way that, in the case of a plurality of columns, each column is connected to a column of the further infiltration trench half-element, so that there are no unconnected columns in the two infiltration trench half-elements.

[0043] In another connection situation, the first infiltration trench half-element with a plurality of columns can be connected to a second infiltration trench half-element with a plurality of columns in such a way that not all columns are connected to each other, leaving unconnected columns. In this installation situation, it is possible, for example, to construct a "masonry connection," with the infiltration trench half-elements arranged, for example, so that they are each connected to two other infiltration trench half-elements.

[0044] However, there are also other installation situations in which more than two infiltration half-elements are connected to one infiltration half-element.

[0045] The final object of the present invention, to provide a receiving, storage or infiltration device, is achieved according to claim 8.

[0046] It was recognized in the present invention that a receiving, storage or infiltration device is particularly technically enhanced if it is constructed from a plurality of infiltration elements as described above.

[0047] Such a receiving, storage, or infiltration device can particularly preferably be used as a trench, a retention basin, or a storage basin. In a further development of the present invention, such a receiving, storage, or infiltration device is surrounded by a fleece to prevent soil from being washed into the device from the outside and to prevent solids from entering the soil from the inside.

[0048] The present invention has broad application in the field of rainwater management. However, the invention can also be used with great advantage in industrial applications, swimming pools, agriculture and pond management, as well as in other areas.

[0049] Further important features and advantages of the invention emerge from the subclaims, from the figures and from the associated description of the figures.

[0050] The present invention is described as follows with reference to the accompanying figures. Fig. 1 a schematic perspective view of a column of a trench half-element; Fig. 2 a schematic side view of a column of a trench half-element; Fig. 3 a schematic cross-section through the column of a trench half-element according to Fig. 2 ; Fig. 4 a further schematic cross-section through the column of a trench half element according to Fig. 2 ; Fig. 5 a schematic side view of two columns of two stacked infiltration half-elements; Fig. 6 a schematic cross-sectional view of two columns of two stacked infiltration half-elements according to Fig. 5 ; Fig. 7 a schematic cross-section through the columns of two stacked trench half-elements according to Fig. 5 ; Fig. 8 a further schematic cross-section through the columns of two stacked trench half-elements according to Fig. 5 ; Fig. 9 a schematic perspective view of a trench half element according to the invention.

[0051] In the Fig. 1 A column 1 of a trench half-element 18 is shown in a schematic perspective view. The trench half-element 18 as a whole is shown in the Fig. 1 not shown. The trench half element 18 is in Fig. 9 shown.

[0052] The column 1 of the infiltration half-element 18 is approximately shaped like a truncated pyramid, i.e. its cross-section decreases continuously from the base 12 of the column 1 to the end 3 of the column 1.

[0053] The column 1 has a wall 5 on which an outer surface 6 is formed. The column 1 is square, with a recess 7 formed on each side of the column 1, which increases in size toward the end 3 of the column 1. The recess 7 becomes continuously deeper and wider toward the end 3 of the column 1.

[0054] At the end 3 of the column 1, a surface 4 is formed on which a first connecting element 8 is arranged.

[0055] In the Fig. 2 a schematic side view of a column 1 of a trench half element 18 is shown.

[0056] The column 1 of the infiltration half-element 18, which is approximately shaped like a truncated pyramid and whose cross-section decreases continuously from the base 12 of the column 1 to the end 3 of the column 1, has a length L. The length L of the column 1 extends from the base grid 2 of the infiltration half-element 18 to the end 3 of the column 1, at which the surface 4 is formed.

[0057] Column 1 of the infiltration half-element 18 is perpendicular to the base grid 2.

[0058] The wall 5 of column 1 is inclined by an angle α relative to a normal 10 perpendicular to the base grid 2. The inclination of the wall 5 relative to the normal 10 is the same over the entire length L of column 1.

[0059] In the Fig. 3 is a schematic cross-section through the column 1 of a trench half element 18 according to Fig. 2 shown. The Fig. 3 corresponds to the section AA, which in Fig. 2 is marked.

[0060] In the Fig. 3 It can be seen that the thickness of the wall 5 of the column 1 is uniform along the entire circumference of the column 1. The column 1 is hollow, so that a cavity 9, which is delimited by the wall 5 of the column 1, is formed therein.

[0061] In the Fig. 4 is a further schematic cross-section through the column 1 of a trench half element 18 according to Fig. 2 shown. The Fig. 4 shown cross section BB corresponds to the one in Fig. 2 displayed cut BB.

[0062] Analogous to Fig. 4 It is shown here that the thickness of the wall 5 of the column 1 is uniform along the entire circumference. The column 1 has a cavity 9 within it, which is delimited by the wall 5 of the column 1.

[0063] In the Fig. 5 a schematic side view of two columns 1, 1' of two similar stacked trench half elements 18, 18' is shown.

[0064] The infiltration half-elements 18, 18' are stacked in such a way that the column 1' of a infiltration half-element 18' is inserted into the cavity 9 of the column 1 of the infiltration half-element 18. This allows a space-saving arrangement of the infiltration half-elements 18, 18', for example, during production, storage, and transport.

[0065] In the Fig. 6 is a schematic cross-sectional view of two columns 1, 1' of two stacked similar trench half-elements 18, 18' according to Fig. 5 shown.

[0066] By designing the columns 1, 1' of the infiltration half-elements 18, 18' in such a way that the wall 5, 5' of the columns 1, 1' is inclined relative to a normal 10 which is perpendicular to the base grid 2 of the infiltration half-element 18, 18', and that the walls 5, 5' of the columns 1, 1' are each equally inclined over their length L, it is ensured that a column 1' can be inserted into the cavity 9 of a column 1 and that the infiltration half-elements 18, 18' can thus be stacked.

[0067] In the Fig. 7 is a schematic cross-section through the columns 1, 1' of two stacked similar trench half-elements 18, 18' according to Fig. 5 shown. The location of the Fig. 7 shown section BB is the Fig. 5 can be found.

[0068] From the Fig. 7 It is clear that the walls 5, 5' of the columns 1, 1' are each of the same thickness along their entire circumference. Due to the inclination of the walls 5, 5' of the columns 1, 1', the column 1' can be easily inserted into the cavity 9 of the column 1, thus achieving stacking.

[0069] In the Fig. 8 is a further schematic cross-section through the columns 1, 1' of two stacked similar trench half-elements 18, 18' according to Fig. 5 The arrangement of section CC according to Fig. 8 is in the Fig. 5 shown.

[0070] Also from the Fig. 8 It becomes clear that the walls 5, 5' of the columns 1, 1' are of uniform thickness along the entire circumference.

[0071] The thickness of the walls 5, 5' is the same, as is the thickness of the walls 5, 5' in the two sections BB and CC shown.

[0072] In the Fig. 9 A schematic perspective view of a trench half-element 18 is shown. The trench half-element 18 includes a plurality of columns 1 extending approximately perpendicularly from a base grid 2 in one direction.

[0073] The Fig. 9 The illustrated trench half-element 18 has three rows of columns 1 in the spatial direction x. Four rows of columns 1 are formed in the spatial direction y.

[0074] In this way, the trench half element 18 according to Fig. 9 twelve pillars 1 formed.

[0075] The columns 1 have on their surface 4, which is formed at the end 3 of the columns 1, either a first connecting element 8 or a second connecting element 11.

[0076] In the execution according to Fig. 9 the three columns of each row have a uniform first connecting element 8 or a second connecting element 11 in the spatial direction x.

[0077] From the infiltration half-element 18, a further infiltration half-element 18, which is rotated by 180° about the x-axis (spatial direction x), can be formed in a simple manner by connecting the first connecting elements 8 with the second connecting elements 11 to form an infiltration component 19 for the construction of a receiving, storage or infiltration device 20.

[0078] For this purpose, a trench half-element 18 can be connected to another trench half-element 18 in such a way that there are no unused first connecting elements 8 or second connecting elements 11.

[0079] In another connection technique, a trench half-element 18 can also be connected to another trench half-element 18 in such a way that first connecting elements 8 and / or second connecting elements 11 are still unused on both trench half-elements 18, thus enabling a "masonry connection." In a "masonry connection," a trench half-element 18 is connected to at least two other trench half-elements 18, resulting in increased stability of the trench component 19 and thus of the receiving, storage, or infiltration device 20 to be constructed.

[0080] The infiltration half-elements 18, 18' are shaped so that they can be stacked on top of each other in a space-saving manner, with a column 1' of a lower infiltration half-element 18' being inserted into the cavity 9 of a column 1 of an infiltration half-element 18 arranged above it.
