Definitions

  • the invention relates to an embankment protection device, which serves the introduction into or filling with soil, comprising a böschungs person to be arranged, in the height and horizontally extending grid structure comprising a plastic or wire mesh and a fixed thereto grid, wherein the plastic or wire mesh means the support grid to form an upper and a lower horizontal leg and a connecting, upstanding and supported on the support grid, which is supported via one or more support members to the lower leg, supported leg can be erected.
  • embankment protection devices are used in embankment structures.
  • embankment structures can be of different types.
  • dyke structures which have at least on the water side a corresponding embankment and the other possibly flat, or have on both sides corresponding slopes.
  • earthworks that run along road structures.
  • suitable embankment protection devices are installed for soil stabilization or subsoil stabilization.
  • Such an embankment protection device which is introduced into the soil or filled with it, usually comprises a bow-sided side to be arranged, in the height and horizontally extending grid construction.
  • Such a grid construction may be an angled structure which extends with one leg in the height and roughly defines, for example, the slope angle, while the other legs extend horizontally and the binding length, ie the length with which the slope protection device is anchored in the horizontal in the ground , define.
  • Other grid structures such as gabions and the like are known.
  • slope protection means By using such slope protection means, it is possible to sufficiently strengthen the slope so that it has the desired basic stability have. It is also possible using such safety devices to build up overhanging slopes and secure. This reinforcement must be designed in such a way that it gives the embankment structure the necessary stability, but at the same time also ensures the internal and external stability and enables extensive erosion protection.
  • Such an embankment protection device is off DE 10 2014 101 334 A1 known.
  • the invention is based on the problem of providing a contrast improved embankment protection device.
  • the support grid is a plastic plate having a plurality of perforations.
  • a plastic plate is used as a support grid, which has a plurality of apertures over its surface, so that a greening of the embankment structure is possible over the openings. Nevertheless, the plastic plate, which still offers a sufficiently large support surface despite the perforations, at the same time a good erosion protection, that is, the soil is securely retained. The additional integration of an anti-erosion mat is therefore not required. Furthermore, such a plastic plate is also characterized by a sufficiently high stability and bending and torsional stiffness, which is also beneficial for a secure support of the poured soil.
  • the plastic plate itself should have a thickness of at least 2 cm, in particular of at least 3 cm and preferably of 4 cm.
  • the openings themselves can have any round, triangular, quadrangular or polygonal shape.
  • the openings should have a hexagonal, honeycomb shape. This geometry allows the arrangement of the apertures with over the surface constant web width, as can be achieved due to the aperture distribution and the web arrangement a high plate stability.
  • the webs themselves should have a width of at least 10 mm between the angular openings, that is to say they should be sufficiently defined.
  • the webs have a width of at least 3 mm, in particular of at least 6 mm and at the back of the support grid, so towards the ground, are widened. That is, either sufficiently broad webs are provided by the house, so that there is a sufficiently large retention surface, or that when using thinner webs back a web broadening is provided, which provides the increased retention area.
  • a plastic plate with openings in honeycomb form is particularly preferred.

This is done very quickly, combined with a very firm and secure fixation of the plastic or wire mesh, after the bar or the strips preferably extend over almost the entire length of the plastic plate.
  • the or each strip is preferably connected via a plurality of fastening means with the plastic plate, in which case different fastening means can be used.
  • screws are used as fastening means, which pass through the bar and are screwed directly into the plastic plate.
  • the or each bar is provided for example with corresponding through holes through which the screws engage.
  • the plastic plate by itself a sufficiently large back surface, only interrupted by the openings, has, it is readily possible to screw the screws immediately back in the plastic plate. If, for example, the plastic plate is formed from one or more turf honeycombs, sufficiently large rear surfaces are provided both in the region of the webs and in particular in the region of the crossing points, into which the screws can be screwed.
  • the fastening means have hooks which are fastened to the strip and penetrate openings in the plastic plate and engage therewith. It is conceivable, for example, to push the hooks from the front of the panel through an opening until the hook hooks onto a bar. The opposite, for example, provided with an external thread hook part is pushed through a through hole of the bar and fixed from the other side with a nut. Again, this can be a simple and secure and fast fixation.
  • a common angle between the lower horizontal leg and the obliquely extending leg is, for example, approximately 70 °, in particular for an overhanging embankment.
  • a further strip which is arranged on the lower horizontal leg of the plastic or wire mesh and via connecting elements with the plastic or Wire grid is connected to which bar one or more rod-shaped support elements are supported in the Verbaudian.
  • This strip which may be a wood, metal, plastic or plastic composite strip, for example, is also firmly connected to the plastic or wire mesh, it can be placed above or below the grid. Due to the attachment to the grid consequently a defined distance to the support grid respectively the plastic plate is given.
  • one or more rod-shaped support elements are used, which are fixed on the one hand on the support grid, in particular a provided on the rear side bar and on the other hand on the bar attached to the horizontal leg.
  • the length of the supporting elements or the distance between the further strip and the plastic strip is dimensioned such that the desired angle of attack results.
  • the bar attached to the horizontal leg also serves as a push threshold, which additionally counteracts a soil movement.
  • the support elements are or are preferably fixed to a strip fastened to the back of the plastic plate.
  • This bar is preferably located in the region of the upper edge of the support grid or the plastic plate.
  • corresponding holding elements are provided for fixing the or the support elements.
