Description

trench arrangement

The invention relates to a trench arrangement, comprising a base having a number of openings and a number of columns connected to the base and projecting approximately vertically, the columns having a wall, the columns arranged in a grid with at least one row of columns and at least one Column columns are arranged.

In addition, the invention also relates to a trench system; a receiving, storage or infiltration device; as well as a transport system which are constructed from trench arrangements.

Trenches, which serve to absorb, store or infiltrate fluids, especially rainwater, are assembled from individual elements. In particular, trench arrangements are used for this purpose, which have a base lattice, with columns rising approximately perpendicularly from the base lattice. Connecting devices are used to connect the trench arrangement at the tops of the columns, ie at the column ends that are opposite the base grid. For this purpose, the columns can either be placed loosely on top of one another or joined together by means of snap-in connections.

In order to arrange such trench arrangements in a space-saving manner during manufacture, storage and transport, the columns are hollow so that such trench arrangements can be stacked by the columns of an adjacent trench arrangement being insertable into the cavity of the columns of a trench arrangement.

The trench arrangement as part of a receiving, storage or infiltration device has to withstand certain forces which, on the one hand, result from the underground installation of such an receiving, storage or infiltration device. Here, an earth pressure acts on them and possibly also the hydrostatic pressure of the rainwater collected in them, on the other hand, traffic loads from the traffic routes located above them have to be absorbed. The pillars of the infiltration system serve to transfer the forces in the vertical direction. These are to be designed according to the mechanical and static requirements.

When designing the columns for a trench arrangement with regard to the requirement for the transmission of forces, there are always problems, especially if this type of column is also to be designed for the possibility of stacking the trench arrangements.

EP 0943737 discloses a trench assembly, in particular an irrigation and/or drainage box, having a base provided with perforations and side walls provided with perforations and integrally connected to the base, with the box at the side is open facing the base, and the box is formed at the open side in such a way that two identical boxes can be placed open-sided and connected to each other without the need for additional accessories, the side walls being substantially perpendicular to the base, that the box has pillars extending substantially perpendicularly from the base to the open side, and that at least some of the pillars on the open side of the box are provided with first connecting parts and other pillars on the open side of the box are provided with second connecting parts, such that when two identical boxes according to the invention are placed against each other with the open sides, the first connecting parts of one of the two identical boxes are able to cooperate with the second connecting parts of the other of the two identical boxes to establish a connection between the two identical boxes to build.

The disadvantage of the prior art is that for intended use, so-called side walls with perforations must always be provided, which, on the one hand, drive up the costs of producing such trench arrangements, which, due to their large-volume construction, require more space, especially during transport and storage, and This also causes increased costs for transport and storage.

It is an object of the present invention to overcome the disadvantages of the prior art and to develop a trench arrangement of the type mentioned at the outset in such a way that it can be produced economically and inexpensively, has a simple and stable structure, can be used without additional attachments and whose transport volume is considerable is smaller/reduced to the storage volume. A further object of the present invention is to specify a trench system. It is also an object of the invention to specify a receiving, storage or infiltration device which is constructed from trench arrangements.

Finally, the object of the invention is also to show a transport system that has trench arrangements.

The first object is achieved according to claim 1. Further advantageous refinements are disclosed in the subclaims which refer back thereto.

It has surprisingly been found that a trench arrangement comprising a base having a number of openings and a number of columns connected to the base and projecting approximately vertically, the columns having a wall, the columns arranged in a grid with at least one row of columns and at least one column of columns are arranged, is characterized in that the columns of a row of columns and/or a column of columns are arranged at a distance from one another via at least one first opening in the base, that at least one row of columns and/or a column of columns are arranged on at least one edge of the base is that at least one row and/or column of columns is spaced from at least one edge of the base by at least one row of openings and/or column of openings. With the trench arrangement, it is thus possible for the first time to produce this economically and cost-effectively, the trench arrangement having a simple and stable structure, can be used without additional attachments and whose transport volume is significantly smaller/reduced to the functional volume/storage volume. It was found that with the infiltration system, optimal statics, an index strength of at least 320 kN/m ² , preferably at least 400 kN/m ² in the vertical direction and at least 80 kN/m ² , preferably at least 100 kN/m ^{2 ,} can be achieved in the horizontal direction after index testing according to RAL quality guideline RAL-GZ 994/11 with a load increase of 0.5 kN/m ² s. The advantage of the infiltration system is that it can be used as intended without additional attachments or side rails, which affects the production, Storage and transport costs are once again significantly reduced.

Another advantage of the trench arrangement is that with an optimal storage volume of at least 95%, preferably about 96.5%, particularly preferably about 97%, a very minimal material consumption in the production of about 8 dm ³ , preferably about 30 l / m ³ storage volume. The trench arrangement advantageously has a weight of around 7 kg when using a material with a density of around 900 kg/m ³ according to standard DIN ISO 1183-1:2019-09.

The infiltration system is also designed in such a way that with a very small component volume of at least 0.15 m ³ , preferably around 0.2 m ³ , it also requires very little storage or storage space. has transport volume. Due to the optimal design and geometry of the trench arrangement, it is extremely easy to assemble and can be quickly assembled into trench systems and into storage, storage or infiltration devices. In particular, due to the optimal point-symmetrical geometry of the trench arrangement, it can be quickly assembled at any time to form small-volume and space-saving transport systems.

An advantage of the trench arrangement is that the column has a constant cross-section throughout its length (L). As a result, on the one hand economical and inexpensive production costs can be realized and on the other hand the statics (index strength) of the trench arrangement can surprisingly be adapted or optimized at any time to the corresponding legal requirements and the requirements of the corresponding project construction sites.

Another advantage of the trench arrangement is that the column has an approximately polygonal and/or a cylindrical and/or an oval, in particular a rectangular and/or a square, cross section. These geometric variations allow the arrangement of trenches to be easily adapted to the respective legal requirements with regard to their statics (index strength) at any time.

It has also been found to be advantageous in the trench arrangement that the column is designed as a cuboid, three-dimensional body. In this embodiment, the trench arrangement is optimized in particular in terms of statics (index strength) and adapted to the corresponding requirements.

Another advantage of the trench arrangement is that the opening of the base of the trench arrangement also has an approximately polygonal and/or a cylindrical and/or an oval, in particular a rectangular and/or a square, cross section. The geometric variants of the opening of the base of the trench arrangement are adapted to the geometry/cross-section/circumference of the columns, since these Trench arrangement is designed so that at least for transport or with the transport systems, the respective columns can always be introduced into the openings in the base of the trench arrangement, so that they are designed approximately analogously or identically in cross section.

It was also found to be advantageous that in particular the circumference of the opening of the base of the trench arrangement is approximately the same as the circumference of the cross section of the column. This ensures that, despite the usual manufacturing tolerances, for example, the respective columns can always be introduced into the openings in the base of the trench arrangement without any problems.

In the prior art, the trench arrangements are stacked one inside the other in such a way that the columns of one trench arrangement can be pushed into the cavity of the columns of another trench arrangement.

It has also turned out to be advantageous in the trench arrangement that in particular the circumference of the opening of the base of the trench arrangement is larger than the circumference of the cross section of the column. The trench arrangement is characterized in that, on the one hand, this ensures stability and strength, while on the other hand the individual trench arrangements can be assembled into transport systems quickly and in a space-saving manner.

Another advantage of the trench arrangement is that the walls of the columns delimit a cavity. On the one hand, this leads to an optimal weight of the trench arrangement and, on the other hand, to better nesting of individual trench arrangements. Another advantage of the trench arrangement is that the wall of the columns facing at least one edge of the base has an area of at least 50 cm ² , preferably 100 cm ² . This configuration of the trench arrangement ensures its stability and strength both in the vertical direction and in the horizontal direction, while on the other hand there is still enough surface area of the trench arrangement for the intended use, namely the absorption of water, especially rainwater.

It is also advantageous in the trench arrangement that the open area between two columns arranged at a distance above a first opening of the base is at least 70 cm ² , preferably 100 cm ² , particularly preferably 150 cm ² . This represents arrangement ensures that even with larger amounts of water, especially in heavy rain, this can be absorbed briefly in the functional or storage volume of the infiltration system.

The trench arrangement is advantageously designed such that the entire area of the column row/or column column pointing to at least one edge of the base is at least 15 dm ² , preferably about 20 dm ² , particularly preferably about 25 dm ² . In this way, in particular, the stability and strength of the trench arrangement can be realized at any time.

A further advantage of the trench arrangement is that the open areas of the row of columns and/or column columns pointing to at least one edge of the base have at least 5 dm ² , preferably 10 dm ² , particularly preferably 12 dm ² . It has surprisingly been shown with the trench arrangement that this geometric design makes it possible without any problems to absorb accruing amounts of water, for example in the case of low precipitation, but also large amounts of water, for example in the event of heavy rain, at any time in an optimal period of time in the storage volume of the trench arrangement.

In a further advantageous embodiment of the trench arrangement, it is designed in such a way that the columns are connected to one another at least partially at their first end, which is connected to the base, via at least one connecting element. As a result, in particular the stability and the strength of the trench arrangement can be further improved or optimized.

It is also advantageous in the trench arrangement that the columns, at their first end connected to the base, at least partially enclose at least one second opening of the base via at least two connecting elements arranged opposite one another. This in turn makes it possible, in particular, to design or ensure the stability and strength of the trench arrangement.

The trench arrangement is advantageously designed in such a way that at least one opening in the base has at least one stiffening element at the edge. This advantageously means that the stability and strength of the trench arrangement is optimized, particularly in the area of the base, and that this provides support when the trench arrangements can be guided together to form transport systems. Furthermore, the trench arrangement is designed in such a way that the base has a reinforcing element on at least one edge. On the one hand, this leads to a further optimization of the stability or strength of the trench arrangement and, on the other hand, to easy and simple handling when transporting or installing the trench arrangement to regular systems or to a receiving, storage or infiltration device.

It is also advantageous in the trench arrangement that at least one column and/or a base and/or a lattice arrangement has at least one identification element. Product or material or manufacturer identifiers can thus advantageously be attached to the trench arrangement, such as a corresponding barcode, a QR code or also RFIDs.

It has also turned out to be advantageous in the trench arrangement that the column has at least one first connecting element on its second free end opposite the base.

Another advantage of the trench arrangement is that the column has at least one second connecting element on its first end, which is connected to the base. On the one hand, this ensures that the trench arrangement can be produced economically and cheaply, since the connecting elements in particular are of simple geometric design and, on the other hand, it ensures that individual trench arrangements can be connected via the first connecting elements and the second connecting elements to regular systems or to receiving, storage or Infiltration device are easily mountable.

It has also been found to be advantageous in the trench arrangement that the first connecting element and the second connecting element have a shape that is complementary to one another, at least in sections.

It is also advantageous in the trench arrangement that the first connecting element and/or the second connecting element can be connected to one another, preferably latched. These connecting elements can be produced economically and cost-effectively and, when the trench arrangement is used as intended, they can be assembled together quickly, without tools and with little effort to form regular systems or to form reception, storage or infiltration devices.

A further advantage of the trench arrangement has been found to be that it consists of or contains a polymer material, the polymer material preferably being a is a thermoplastic polymeric material, particularly a polyolefin such as polyethylene, polypropylene, polybutylene, or a copolymer of the foregoing, or a blend composition of the foregoing, or a polyvinyl chloride, or a polyester, or a polycarbonate. However, it is within the scope of the invention that the polymer portion has at least portions of recycled material. Amounts of about 50 to 100% by weight, preferably even 70 to 100% by weight, based on the total weight, have proven advantageous here. As a result, the trench arrangement can be produced economically and inexpensively, has a low weight in relation to the functional or storage volume and is corrosion-resistant when used as intended.

The polymer materials mentioned are easy to shape, stable, durable, and mechanically resilient to purchase at low cost. The trench arrangements can be produced from these polymer materials in a simple manner, inexpensively and economically. This can be implemented, for example, in an injection molding process or in another polymer processing process.

Alternatively, it is possible for the trench arrangement to be able to be produced using an additive manufacturing process, in particular in one piece, for example using a 3D printing process.

Three-dimensional models that can be read by data processing machines can advantageously be used to produce the trench arrangement.

The invention also includes a method for generating a data processing machine-readable, three-dimensional model for use in a manufacturing method for a trench arrangement.

In this case, the method also includes in particular the input of data representing a drainage trench arrangement into a data processing machine and the use of this data to represent drainage trench arrangements as three-dimensional models, the three-dimensional model being suitable for use in the manufacture of a drainage trench arrangement.

The trench arrangement can be produced in whole or in part using a line-building or layer-building manufacturing process. A 3D data record can be used with great advantage during construction or production. Also included in the method is a technique in which the input data is fed to one or more 3D scanners, operating either in touch or in a non-contact manner, in the latter of which energy is delivered to a trench arrangement and the reflected energy is received, and a virtual three-dimensional Model of a trench arrangement below generated using computer-aided design software. The manufacturing process can be a generative powder bed process, in particular selective laser melting (SLM), selective laser sintering (SLS), selective heat sintering (Selective Heat Sintering - SHS), selective electron beam melting (Electron Beam Melting - EBM / Electron Beam Additive Manufacturing - EBAM) or solidification of powder material by means of a binder (binder jetting). The manufacturing process can be a generative free space process, in particular build-up welding, wax deposition modeling (WDM), contour crafting, metal-powder application processes (MPA), plastic-powder application processes, cold gas spraying, electron beam melting (electron beam welding - EBW) or melt layering processes such as fused deposition Modeling (FDM) or Fused Filament Fabrication (FFF). The manufacturing process can include a generative liquid material process, in particular stereolithography (SLA), digital light processing (DLP), multi-jet modeling (MJM), polyjet modeling or liquid composite molding (LCM). Furthermore, the manufacturing method can include other generative layer construction methods, in particular Laminated Object Modeling (LOM), 3D screen printing or light-controlled electrophoretic deposition.

The solution to the further object of the present invention, to specify a trench system, is achieved with the features of claims 17 and 18.

The invention further relates to a drainage system with at least one drainage system according to the previous statements, which is characterized in that a first drainage system is arranged with its second free end of the columns projecting away from the base on at least one lattice arrangement. This makes it possible to provide a drainage system that can also be used to achieve low or half overall heights with the same water absorption capacity and stability of the drainage system. Another advantage of the trench system is that it is compatible with other system components such as regular boxes, shafts and similar components.

Furthermore, the invention relates to a drainage system with at least two drainage systems according to the previous statements, which is characterized in particular by the fact that a first drainage system has its second free end of the columns projecting away from the base arranged at the oppositely arranged first openings of a base of a second drainage system are. Due to this geometry of the infiltration system, the infiltration system can be assembled very quickly, without tools or additional lifting gear (cranes) with the appropriate number of infiltration systems. The solution to the additional object of the present invention of showing a receiving, storage or infiltration device is achieved with the features of claim 19 and with a plurality of trench arrangements according to the previous statements.

Such a receiving, storage or infiltration device can preferably be used as a trench, as a retention basin or as a storage basin. In a further embodiment of the present invention, such a receiving, storage or infiltration device is completely surrounded by a fleece so that the soil in this device is not a swimming pool from the outside or that no solids penetrate from the inside into the surrounding soil.

Finally, the last object of the invention, to show a transport system, is realized by the features of claims 20-22.

The transport system consisting of at least two trench arrangements according to the previous statements is characterized in that at least one first trench arrangement with its column rows/or column columns spaced apart from the edge of the first base is arranged orthogonally offset to a second trench arrangement in such a way that at least one column row and/or or a column column of the second trench arrangement can be introduced into the openings of the row of openings and/or the column of openings arranged at a distance from at least one edge of the first base of the first trench arrangement. As a result, it is surprisingly possible for the first time to provide a transport system which, for example with four trench arrangements arranged one inside the other, has the same overall height as a single trench arrangement. Advantageously, here are the transport or. Storage volume significantly reduced, so that in particular the costs for storage, transport and assembly are also reduced.

Another advantage of the trench arrangement is that the opening of the base of the trench arrangement also has an approximately polygonal and/or a cylindrical and/or an oval, in particular a rectangular and/or a square, cross section. The geometric variants of the opening of the base of the trench arrangement are adapted to the geometry/cross section/circumference of the columns, since this trench arrangement is designed in such a way that the respective columns can always be introduced into the openings of the base of the trench arrangement, at least for transport or with the transport system are, so that they are approximately analogous or of the same shape in cross section. It was also found to be advantageous that in particular the circumference of the opening of the base of the trench arrangement is approximately the same as the circumference of the cross section of the column. This ensures that, despite the usual manufacturing tolerances, for example, the respective columns can always be introduced into the openings in the base of the trench arrangement without any problems.

The transport system is further distinguished by the fact that at least one trench arrangement has a point-symmetrical geometry. Point symmetry within the meaning of the invention means that the trench element can be imaged onto itself by being reflected at a point of symmetry.

The trench elements can be stacked by turning them orthogonally to a trench element underneath. When stacked, the columns of the trench elements located further below are pushed through the overlying openings of the lattice arrangement. As a result, a transport system can be made available which is characterized in that the height of four trench arrangements arranged one inside the other is approximately the same as the height of a single trench arrangement.

The transport system with at least two trench arrangements is also designed in such a way that with a very small component volume of at least 0.15 m ³ , preferably about 0.2 m ³ , there is also a very minimal storage or has transport volume. Due to the optimal design and geometry of the trench arrangement to be transported, this is extremely easy to assemble and can be quickly assembled into trench systems and into receiving, storage or infiltration devices. In particular, due to the optimal point-symmetrical geometry of the trench arrangement to be transported, this can be quickly assembled at any time to form small-volume and space-saving transport systems.

The advantage of the transport system consisting of at least two trench arrangements is that the height (HT) of four trench arrangements arranged one inside the other is approximately the same as the height (H) of a single trench arrangement. However, it is also within the scope of the invention for the height (HT) of the transport system consisting of at least two trench arrangements to be slightly higher than the height (H) of a single trench arrangement. It is also within the scope of the invention that the distance between two trench arrangements arranged one inside the other is approximately % of the total height of a single trench arrangement.

Furthermore, it is within the scope of the invention that the overall height of a transport system corresponds approximately to the overall height of an individual trench arrangement and to a multiple of the distance between trench arrangements arranged one inside the other.

This advantageously leads to an extremely small or reduced volume of the transport system.

Other important features and advantages of the invention result from the dependent claims, from the figures and from the following descriptions of the figures.

FIG. 4 shows a schematic, perspective representation of a trench system 100.

The drainage system 100 has several drainage systems 10, 10'. The trench arrangements 10,10' are arranged side by side and next to one another.

In this exemplary embodiment, the trench system 100 is designed in such a way that first trench arrangements 10 are arranged on at least one lattice arrangement 1 with their second free end 3 of the columns 30 projecting away from the base 20 . The lattice arrangement 1 thus forms a possible basis for the construction or assembly of a trench system 100 or a receiving, storage or infiltration device 200.

The trench arrangement 10 is fixed here via connecting elements, which cannot be seen here, which are arranged on the columns 30 and the openings of the lattice arrangement 1 .

The drainage system 100 is also designed in such a way that further drainage systems 10' are arranged on the first drainage system arrangement 10.

The second trench arrangement 10' is arranged in such a way that the second free ends 3' of the columns 30' projecting away from the base 20' are arranged on the base 20 of the first trench arrangement 10.

The second trench arrangement 10' is designed in such a way that second connecting elements, which cannot be seen in this illustration, are arranged on the second free end 3' of the column 30'.

The trench arrangement 10, 10' of the trench system 100 is designed in such a way that first connecting elements and/or second connecting elements can be connected to one another, preferably latched.

However, it is also within the scope of the invention for the trench system 100 to have a large number of trench arrangements 10, 10' arranged one above the other and fixed to one another.

It is also within the scope of the invention for the drainage system 100 to be designed in such a way that a first drainage system arrangement 10 has its second free end 3 of the columns 30 protruding away from the base 20 at the oppositely arranged first openings 22' of a base 20 'A second trench arrangement 10' is arranged. The infiltration system 100 is further distinguished by the fact that it can be used without additional add-on parts, in particular the costly and assembly-intensive side parts, and can be assembled, for example, to form an optimal receiving, storage or infiltration device 200 .

A schematic perspective view of a transport system 300 is shown in FIG. In this exemplary embodiment, the transport system 300 has four trench arrangements 10, 10″.

The transport system 300 is characterized in that at least one first trench arrangement 10 with its column rows 6 and/or column columns 7 spaced apart from the edge 21 of the first base 20 is arranged so orthogonally offset to a second trench arrangement 10" that at least one column row 6 and/or a column column 7 of the second trench arrangement 10" can be introduced into the second openings 23 of the row of openings 80 or the opening column 90, which are arranged at a distance from at least one edge 21 of the first base 20 of the first trench arrangement 10.

In this exemplary embodiment, the trench arrangements 10,10" are arranged in such a way that, for a better overview and description of the insertion/mounting into one another, they are shown spaced apart from one another by their base 20,20".

In the final state, the transport system 300 is designed in such a way that the respective base 20, 20″ of the trench arrangement 10, 10″ is arranged lying on one another, spaced apart from one another via at least one connecting element 4, 4″.

The respective columns 30,30" of the trench arrangement 10,10" are arranged next to one another at approximately the same height in the final state.

The transport system 300 is further designed, at least in the final state, such that the height H of four trench arrangements 10,10", 10,10" arranged one inside the other is approximately the same as the height H of a single trench arrangement 10,10".

This final state can advantageously be realized in that at least one trench arrangement 10, 10'' has a point-symmetrical geometry.

The transport system 300 with at least two trench arrangements 10, 10″ is also designed in such a way that with a very small component volume of at least 0.15 m ³ , preferably around 0.2 m ³ , there is also a very minimal storage or has transport volume. Due to the optimal design and geometry of the 10,10" trench arrangement to be transported, it is extremely easy to assemble and can be quickly assembled into trench systems 100 and into receiving, storage or infiltration devices 200. In particular, due to the optimal point-symmetrical geometry of the 10,10″ trench arrangement to be transported, this can be quickly assembled at any time to form small-volume and space-saving transport systems 300. The advantage of the transport system 300 consisting of at least two trench arrangements 10, 10" is that the height (HT) of four trench arrangements 10, 10", 10, 10" arranged one inside the other is approximately the same as the height (H) of a single trench arrangement 10.

However, it is also within the scope of the invention for the height (HT) of the transport system 300 made up of at least two trench arrangements 10,10" to be slightly higher than the height (H) of a single trench arrangement 10.

It is also within the scope of the invention that the distance between two trench arrangements 10, 10' arranged one inside the other is approximately % of the total height of a single trench arrangement 10.

It is also within the scope of the invention that the overall height of a transport system 300 corresponds approximately to the overall height of an individual trench arrangement 10 and to a multiple of the distance between trench arrangements 10, 10″ arranged one inside the other. This advantageously leads to an extremely small or reduced volume of the transport system 300.

The transport system 300 is characterized in that a first trench arrangement 10 is arranged as a base in such a way that a second trench arrangement 10" is positioned orthogonally offset above the first trench arrangement 10 in such a way that the row of openings 80" is arranged above the opening column 90 of the first trench arrangement 10 is.

The transport system 300 is further designed such that a third trench arrangement 10 is arranged above a second trench arrangement 10″ in such a way that the row of openings 80 is orthogonally offset to the opening column 90″ of the second trench arrangement 10″.

Furthermore, the transport system 300 is designed in such a way that a fourth trench arrangement 10" is arranged in such a way that its row of openings 80" is arranged offset orthogonally to the opening column 90 of the third trench arrangement 10.

The transport system 300 is characterized by this combination of trench arrangements 10,10" by simple assembly and simple handling and is characterized by a minimal storage and transport volume.

FIG. 6 shows a schematic perspective view of four trench arrangements 10, 10'' arranged one behind the other.

The trench arrangements 10,10" are spaced apart, shown one behind the other, that the row of openings 80" of the second Trench arrangement 10' is arranged parallel to the opening column 90 of the first trench arrangement 10 (shown on the far right).

The third trench arrangement 10 is in turn arranged in such a way that its row of openings 80 is positioned parallel to the oppositely arranged opening column 90' of the second trench arrangement 10'.

The fourth trench arrangement 10' is arranged in such a way that its row of openings 80' is positioned parallel to the opening columns 90 of the third trench arrangement 10 arranged opposite.

By pushing the four trench arrangements 10, 10', 10, 10' together until the respective bases 20, 20', 20, 20' of the trench arrangement 10, 10', 10, 10' are arranged directly next to one another, a transport system 300 is created .
