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 lattice structures are produced by injection molding, this means complicated sliding technology and complex injection molds because of the criss-cross lattice openings. For this reason, described in the already mentioned above DE 299 23 050 Ul 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.
  • the object of the invention is to provide a drainage and / or drainage device that can be produced inexpensively and without much effort in injection molding.
  • a drainage and / or drainage device is proposed with the invention, which is provided with a lattice structure through which a passage for the admission of infiltrated liquid to extend, wherein the lattice structure of at least three and preferably four in particular equal parts through which each extending parallel to each other extending grid openings extending from the inside of
  • Passage extend to the outside of the grid structure.
  • the dewatering device is made up of at least three parts, each part having gate openings extending substantially in one direction.
  • a Gittereiement can be produced in a very simple way in injection molding, since no slides are required for demolding, but the demolding is done automatically by moving apart of the injection molds.
  • These Gurgiteretti are placed together, which takes place for example by snap-in connections, gluing or welding or separate fasteners. At least three of these elements together constitute the dewatering device according to the invention, wherein the lattice openings of each element in a circumferential swing corresponding to the pitch! offset from one another (120 ° for three-part and 90 ° for four-part lattice structure).
  • the box or tubular dewatering device is made of several, in particular 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 °.
  • each side of the grid structure has two equal parts which abut each other in the center and are mitered 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.
  • a support wall in the passage which wall supports itself in diametrically opposite regions of two parts of the lattice structure.
  • the stucco wall can thus be oriented vertically (but also horizontally in the installation position of the drainage device).
  • the supporting wall stabilizes the lattice structure of the dewatering device according to the invention against laterally applied earth pressures.
  • the stucco wall may be open, for example, as a grid structure, or be formed closed. In other words, the support wall can thus have through holes.
  • the attachment of the support wall at their contact surfaces with the relevant parts of the lattice structure can be made by snapping or by another frictional connection Rankg.
  • FIG. 1 is a perspective view of a firstFabsbetspiels a box-shaped dewatering device with four identical lattice structural parts
  • FIG. 2 is a plan view of one of the grid structure elements according to II of Fig. 1,
  • FIG. 3 shows an alternative embodiment of a four-part grid structure with respect to the embodiment of FIG. 1 different division
  • Fig. 4 is a round dewatering device in tubular form with four equal lattice structural parts and
  • FIG. 5 shows a perspective view of an eight-part lattice structure dewatering device.
  • the Fign. 1 and 2 show a first Ausbowungsbeispie! a box-shaped dewatering apparatus 10 having a grid structure composed of four natural grid structure parts 12.
  • Each lattice structure part 12 has a plurality of intersecting longitudinally and transversally running lattice struts 14, 16 on f between which lattice openings 18 are formed.
  • the four lattice structure parts 12 form between them and each other a passage 20 f which extends longitudinally through the box-shaped dewatering device 10. Openings 24 are located on the inner side 22 of the passage 20 with the grid openings 18.
  • a nonwoven in particular Geotext TM
  • the water to be infiltrated is led via discharge pipes (not shown) into the passage 20, where it penetrates via the openings 24 into the lattice openings 18 and their openings and finally spreads over the entire dewatering device 10.
  • discharge pipes not shown
  • Several dewatering devices according to Figs. 1 and 2 may be arranged side by side, above and behind each other, wherein adjacent dewatering devices may be secured against unintentional relative displacements by pin-hole connections, separate connection elements or in another manner.
  • each lattice structure part 12 can be produced in a simple manner by injection molding. ments 18 of each lattice structure 12 paralle! extend to each other, the demolding of the injection-lattice Strukturteifs 12 can be done by simply Auseina ⁇ derfahren the Spritzgussforrnkoriften. A slider technique o. Dgi. Complex demolding technique is not required.
  • Fig. 3 is also a box-shaped dewatering device 10 'is shown, in which the individual components of the dewatering device 10 according to FIGS. 1 and 2 corresponding elements with the same reference numerals as in FIGS. 1 and 2 are designated.
  • the difference between the dewatering device 10 'and the dewatering device 10 of FIGS. 1 and 2 is the subdivision of the dewatering device into the individual lattice structure parts 12. While these parts 12 are shown in the embodiment of FIGS. 1 and 2 extend along the edges of the box-shaped dewatering devices 10 and are thus relatively flat, the lattice structure parts 12 in the dewatering device 10 'of FIG. 3 run at a corner, so that for producing a lattice structure part 12 of the dewatering device 10' a slightly higher Injection mold is required as in the case of perennialsbeispieis according to FIGS. 1 and 2,
  • each grid structure part 12 extends in the embodiment of FIG. 4 over a Winkeibe- range of 90 °
  • FIG. 5 shows a further exemplary embodiment of a box-shaped dewatering device 10 '"
  • the grid structure of this dewatering device 10"' likewise has four identical lattice structure parts 12, which are in turn constructed of intersecting lattice struts 14, 16.
  • lattice structure parts 12 which are in turn constructed of intersecting lattice struts 14, 16.
  • the grid openings 18 are in turn open to the passage 20 through openings 24.
  • the connection of the lattice structure parts 12 of the previously described exemplary embodiments of the dewatering device is preferably carried out by welding, gluing or by locking adjacent lattice structure parts by means of latching or Mattselernente,
  • the connection structure must be such that they act on the static loads that affect the dewatering device via the soil, withstand.
  • the individual lattice structure parts 12 each have a symmetrical lattice structure.
  • the grid structure can advantageously also be asymmetrical (with respect to a longitudinal axis extending or transverse thereto symmetry axis), It is also possible at lower expected in the installed state loads the lattice structure parts 12 of the figures in turn each of two to assemble the same components as shown in FIGS. 1 and 5 is indicated at 25 indicated. This would z.
  • the drainage devices of FIGS. 1 and 5 consist of eight equal lattice structural parts (symmetrical division of the parts assumed in the longitudinal extension of the passages).
  • 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 Ent- washing apparatus 10 '"is increased.
