Definitions

  • the invention relates to a device for creating preferably plantable embankments according to the preamble of claim 1.
  • Such devices serve, for example, to secure or create embankments in road construction.
  • the facilities are filled with soil material that is compacted.
  • a geogrid is placed loosely on the floor grid or alternatively positively and positively connected to the floor grid.
  • the geogrid which is only frictionally connected to the floor grid, can slip.
  • the invention has the object of providing the generic device in such a way that it can be easily, inexpensively and with little expenditure of time.
  • the floor grid is provided at its edge facing away from the front edge with hooks. They serve as positive locking means for attaching the geogrid.
  • the hooks of the floor grid surround one of the geogrid wires / bars of the geogrid. The hooking process is simple and can be done easily within a very short time and with just one person. As a result, the inventive devices can be created inexpensively within a very short time.
  • the hooks are formed by bent ends of at least part of the grid wires / bars of the floor grid.
  • the bottom grid and the front grille are supported by at least one support element to each other advantageous.
  • the floor grid and the fritter are formed integrally with each other.
  • the front grille is bent according to the slope angle with respect to the floor grid.
  • the floor grid and the front grille are separate components which are hinged together along one edge.
  • the separate components can be transported very space-saving to the installation site, since they can be stacked for transport.
  • the front grille can be easily adjusted to the desired position relative to the floor grille.
  • each slope angle can be easily adjusted at the installation site.
  • the floor grid and the front grille are sufficiently rigid, so that inadmissible deformations in the installation position do not occur.
  • the floor grille or the front grille are provided with hooks on their adjacent edges. They embrace a terminal grid wire / rod of the front grille or the floor grille. As a result, the floor grid and the front grille can be connected to one another by a simple hooking operation. Even if these grids are long, this hooking operation can be performed by one person.
  • the floor grid and the front grille are provided on one narrow side with further hooks, so that a further floor grid and another front grille can be connected.
  • These further hooks in turn encompass an end grid wire / bar of the further adjacent floor grid or front grid.
  • the bottom grid and the front grid have different sized mesh openings. By choosing the appropriate mesh openings, the installation conditions can be taken into account.
  • the mesh openings of the front grid can be smaller than the mesh openings of the floor grid.
  • the facilities described below serve to secure embankments, the visible surfaces are preferably landscaped.
  • the device according to the Fig. 1 to 6 has a bottom grid 1 and a front grid 2, which are integrally formed with each other. Both grids 1, 2 are formed the same and consist of intersecting, preferably perpendicular intersecting bars or wires 3, 4.
  • the advantageous each other vertically crossing grid wires 3, 4 form square mesh openings 5, which may have different cross-sections depending on the application. In the illustrated embodiment, the mesh openings are rectangular.
  • the grid wires 3 are formed at one end to hook 6 ( Fig. 2 and 3 ). These provided with the hooks 6 ends of the grid wires 3 protrude beyond the adjacent end grid wire 4 ( Fig. 1 ). The other end of the grid wires 3 is fixed on the other end grid wire 4 so that this end does not project beyond this end grid wire 4.
  • the grid wires 4 are also formed at one end to hook 7. This end of the grid wires 4 protrudes beyond the adjacent end grid wire 3 ( Fig. 1 and 3 ). The other end of the grid wires 4 is fixed on the other end grid wire 3 so that the end does not protrude above it.
  • the intersecting wires 3, 4 are connected to each other at the crossing points, preferably welded.
  • the grid wires 3, 4 are preferably made of metallic material, which gives the floor and the front grille 1, 2 a high strength. It is also possible to manufacture the bottom and front grills 1, 2 from plastic wires or rods.
  • each grid wire 3, 4 is provided at one end with a hook 6, 7. It is of course possible to provide only a portion of the grid wires 3, 4 with hooks.
  • the hooks 6, 7 are shaped to point towards the inside of the device.
  • the front grille 2 is bent by the slope angle ⁇ with respect to the bottom grid 1.
  • ⁇ for example, 70 °.
  • the front grille 2 is bent relative to the floor grid 1.
  • the hooks 6 are provided on the one narrow side 8 of the bottom grid 1 and the one narrow side 9 of the front grid 2.

  • the geogrid 16 is in a similar manner as the bottom and the front grille 1, 2 of intersecting plastic wires 17, 18.
  • the end hooks 7 of the floor grid 1 protrude through the mesh openings 19 of the geogrid 16 and engage over the corresponding grid wire 18.
  • the geogrid 16th is at least on the bottom grid 1, but may also extend over part or the entire height of the front grille 2.
  • the area between the floor grid 1 and the geogrid 16 lying thereon and the front grid 2 is backfilled with the respective material, which is optionally compacted.
  • This material presses the geogrid 16 firmly on the floor grid 1, so that the geogrid 16 is positively secured not only by the hooks 7, but by the overlying backfill material and non-positively against displacement. Since the geogrid 16 must be hung only in the hooks 7 of the floor grating 1, a simple and time-saving installation is possible. In particular, the attachment of the geogrid 16 to the floor grid 1 can be easily performed by a person.
  • the device is stiffened by support members 11, 12, which are formed in the embodiments by support rods. They have at their ends respectively hooks 13, 14, with which they are hooked into the corresponding grid wires 3 of the bottom and front grille 2.
  • the support elements 11, 12 can transmit tensile and compressive forces, so that the slope angle ⁇ between the bottom grid 1 and the front grille 2 does not change.
  • the support elements 11, 12 can be easily hooked into the grid wires 3, so that a trouble-free installation is guaranteed.
  • the bottom grid 1 and the front grille 2 are the same design, in particular provided with the same size mesh openings 5.
  • FIG. 7 to 9 show an embodiment in which the bottom grid 1 and the front grid 2 are integrally formed with each other, but in which the front grid 2 has smaller mesh openings 5a than the bottom grid 1. This is achieved in that between adjacent grid wires 4 shorter grid wires 15 are inserted extend over the height of the front grille 2.
  • the grid wires 15 are in each case centrally between adjacent grid wires 4.
  • the mesh openings 5a of the front grid 2 are only half as large as the mesh openings 5 of the floor grid 1.
  • the device according to the Fig. 7 to 9 the same design as the previous embodiment.
  • the smaller mesh openings 5a of the front grille 2 ensure that the backfilled material does not pass through the mesh openings of the front grille to the outside or only to a slight extent when the embankment is erected.
  • the mesh openings 5a of the front grid 2 may have different sizes.
  • two additional grid wires 15 between the adjacent grid wires 4 can be used, resulting in correspondingly small mesh openings.
  • the bottom grid 1 and the front grid 2 are separate wire meshes which are detachably connected to each other in a manner to be described.
  • the floor grid 1 ( 10 to 12 ) has the perpendicular crossing grid wires 3, 4, which form the rectangular mesh openings 5.
  • the grid wires 4 are provided at both ends with a respective hook 7.
  • the grid wires 4 thus protrude beyond the two end grid wires 3.
  • the grid wires 3, 4 have, for example, a wire diameter of 4.5 mm.
  • the mesh openings 5 have an example of a size of 10 cm by 20 cm.
  • the front grille 2 ( Fig. 13 to 15 ) also consists of the perpendicular intersecting grid wires 3 ', 4', which limit the rectangular mesh openings 5 '.

  • the front grille 2 is hooked with its one end grid wire 3 'in the hooks 7 of a longitudinal side of the floor grid 1. Due to the articulated connection of floor grille 1 and front grille 2, any desired angle of repose can be adjusted very easily. It is only necessary, the support elements 4 ( Fig. 6 ) in the floor and the front grille hang. The length of these support elements 4 depends on the slope angle ⁇ , which includes the front grille 2 to the bottom grid 1.
  • the geogrid 16 can easily hang in the manner described, so that it is positively connected to the bottom grid 1.
