Definitions

  • the invention relates to a drainage and / or drainage device (hereinafter called dewatering device), as used for example for the infiltration of surface water.
  • dewatering device a drainage and / or drainage device
  • the known dewatering devices have a box-shaped structure and are usually made of plastic. They are manufactured in injection molding technology. Since the known dewatering devices are flowed through three-dimensionally, they have in several directions extending openings. If such grating structures produced by injection molding, this means because of the criss-cross grid openings a complicated slide technology and complex injection molds. For this reason, in the already mentioned above DE 299 23 050 U1 described to produce a drainage box from two equal half-boxes. However, the production of a half-box already requires a complex slide and injection molding technique.
  • a drainage box which is composed of a plurality of identical, substantially W-shaped plastic grid elements.
  • Each one-piece grid element has a grid base plate with upstanding at two opposite ends of the side grid edges. Between these two side rail edges extends, also from the grid base plate towering a Mittengittererhebung, which divides the grid element into two equal sections, each with a half-passage.
  • a first group of grid openings parallel to each other extends, while the side grid edges have a second group of grid openings that are parallel to each other but transverse to the grid openings of the grid base plate.
  • lattice box To form a lattice box, two lattice elements are now assembled by their side lattice edges and center lattice elevations are adjacent to each other, this lattice box two parallel Having passages.
  • Several such grid boxes can be arranged side by side and / or one above the other.
  • EP-A-1 437 305 a drainage device is known, which is composed of individual differently sized flat grid plates.
  • EP-A-1 437 305 discloses the features of the introductory part of claim 1.
  • the object of the invention is to provide a drainage and / or drainage device that can be produced inexpensively and without great effort in injection molding.
  • the dewatering device is made up of at least three parts, each part having lattice openings, all of which run parallel to each other per part.
  • a grid element can be produced in a very simple manner in injection molding technology, since no slides are required for demolding, but the demolding is done automatically by moving apart of the injection molds.
  • These grid elements are placed against each other, which is done for example by snap-in connections, gluing or welding or separate fasteners. At least three of these elements together form the dewatering device according to the invention, the grid openings of each element being offset relative to one another at a circumferential angle corresponding to the division (120 ° for three-part and 90 ° for four-part grid structure).
  • the box or tubular dewatering device is made of several, ie at least three equal parts, through which grid openings extend, all of which run parallel to each other per part.
  • an eight-part lattice structure can also be constructed with these parts. The division is done every 45 °. If the grid structure has an outer box shape, then each side faces the lattice structure on two equal parts, in the middle on impact to each other lie and are mitred at the corners to a respective adjacent part of the grid structure.
  • the miter arrangement is expediently also given a four-part design of the grid structure.
  • the support wall can thus (in the installation position of the dewatering device) be vertically aligned, but also horizontally.
  • the supporting wall stabilizes the lattice structure of the dewatering device according to the invention against laterally prevailing earth pressures.
  • the support wall can be open, for example as a lattice structure, or closed. In other words, the support wall can thus have through holes.
  • the attachment of the support wall at the contact surfaces with the relevant parts of the grid structure can be done by snapping or by another non-positive connection.
  • FIGS. 1 and 2 show a first embodiment of a box-shaped dewatering device 10 having a grid structure, which is composed of four identical lattice structure parts 12.
  • Each lattice structure part 12 has a plurality of intersecting longitudinal and transverse lattice struts 14, 16, between which lattice openings 18 are formed.
  • the four lattice structure parts 12 form between them and each other a passage 20 which extends longitudinally through the box-shaped dewatering device 10. Openings 24 are aligned with the grid openings 18 on the inside 22 of the passage 20.
  • a nonwoven in particular geotextile
  • dewatering devices may be arranged side by side, above and behind each other, wherein adjacent dewatering devices may be secured by pin-and-mortise joints, separate connection elements or in some other way against unintentional relative displacements.
  • each lattice structure part 12 can be produced in a simple manner by injection molding. Since all lattice openings 18 of each lattice structure part 12 extend parallel to one another, the demolding of the injection-molded lattice structure part 12 can be achieved by simply moving apart the injection mold halves done. A slide technology o. The like. Elaborate Entformungstechnik is not required.
  • the difference of the dewatering device 10 'with respect to the dewatering device 10 of FIGS. 1 and 2 consists in the subdivision of the dewatering device in the individual lattice structural parts 12. While these parts 12 in the embodiment according to the FIGS. 1 and 2 extend along the edges of the box-shaped dewatering devices 10 and thus are relatively flat, extend the lattice structural parts 12 in the dewatering device 10 'of Fig. 3 corner, so that for producing a lattice structural part 12 of the dewatering device 10 'is a slightly higher-build injection mold than in the case of the embodiment of the FIGS. 1 and 2 is required.
  • FIG. 4 A further exemplary embodiment of a box-shaped dewatering device 10 '"is shown,
  • the lattice structure of this dewatering device 10'" also has four identical lattice structure parts 12, which are in turn constructed of intersecting lattice struts 14, 16.
  • the grid openings 18 are in turn open via openings 24 to the passage 20.
  • connection of the lattice structure parts 12 of the above-described embodiments of the dewatering device is preferably carried out by welding, gluing or by locking adjacent lattice structure parts by means of latching or connecting elements.
  • the connection structure shall be such as to withstand the static loads acting on the drainage device via the soil.
  • the individual lattice structure parts 12 each have a symmetrical lattice structure.
  • the grid structure can expediently also be asymmetrical (with respect to a longitudinal axis extending or transverse thereto symmetry axis).
  • the lattice structure parts 12 of the figures in turn from two identical individual parts, as shown in FIGS FIGS. 1 and 4 indicated at 25 is shown. This would z. B. the dewatering devices of FIGS. 1 and 4 consist of eight equal lattice structural parts (symmetrical division of the parts in the longitudinal extension of the passages assumed).
  • a support wall 26 may be disposed in the passage 20, as shown.
  • the support wall 26 is provided in this embodiment with through holes, which form as openings between adjacent lattice struts of the support wall 26.
  • the support wall 26 supports two opposing lattice structure parts 12, whereby the stability of the dewatering device 10 "'is increased.
