Definitions

  • the invention relates to a method for producing a Erdböschung, which is composed of a plurality of compacted Grezierlagen and a reinforced outer skin, in which a load-bearing and consolidated area is built up in layers, which is composed of several layers of filling soil, the layer of each of a substantially horizontal section, a vertical section and a folded-back section of the flexible reinforcement mat is enclosed and compacted.
  • each filler base enclosed by a reinforcing mat is associated with a frame formed of a steel mesh mat having a lower horizontal bottom and a sloping front wall.
  • the front wall is angled away from the horizontal floor, which corresponds to the slope angle.
  • each floor layer is one Assigned grid mat, which is hingedly connected to the grid mat of the respective adjacent base layer.
  • the grid mats of the individual ground layers are held together by guide rods at an angle which corresponds to the angle of repose of the completed earth embankment.
  • guide rods can be removed for further use.
  • the bottom layers can not be highly compressed. The filling of an uncompacted, loose vegetation soil is not possible here.
  • EP-A-0 872 597 is concerned with the manufacture of a reinforced earth embankment having a greener outer skin.
  • densified Art provokelagen be created whose forehead areas are surrounded by geotextile reinforcement mats.
  • the end face of the superimposed Artitzlagen are inclined substantially corresponding to the slope angle.
  • grid mats are arranged to form the greenable outer skin whose height corresponds to the height of a Medbodenlage.
  • each about 50 cm to 80 cm thick layer is formed of filling floor, at least partially enclosed by a flexible geotextile reinforcement mat, especially geogrid mat is.
  • the flexible reinforcing mat has a lower, substantially horizontal portion on which the filling floor rests, on the outside a portion which extends over the height of the respective filling bottom layer, and a folded-back portion, on which the lower portion of the reinforcing mat of the next higher Artgeber für rests.
  • the individual Artgeber füren be compacted by vibrators or vibrating rollers before the next higher Artgeber für is applied.
  • the flexible reinforcing mats are geogrids made of high-modulus polyester yarns with a mesh width of 10 ⁇ 10 mm to 50 ⁇ 50 mm.
  • the polyester yarns or the geogrid is equipped with a polymer protective layer. If the slope wall is substantially vertical, then the vertical sections of the reinforcing mats of the individual Artgeber füren are substantially one above the other in a vertical plane. If the slope wall is inclined by 45 °, then the vertical sections of the Artgeber Anlagenen the next Artgeber harsh are offset by the height of the vertical sections of the reinforcing mats or by the thickness of the Grezier lamb.
  • the mesh size of the reinforcement mat is chosen as a function of the grain size of the filling soil and should be about as large as the grain size of 50% of the filling soil.
  • the invention has for its object to develop a method for producing a Erdböschung in which the filling floor can be reliably compressed, the front side of the reinforcement mat of the Grezier despite the compaction has a defined, as vertical as possible course and in which regardless of the compacted Greigelagen Vegetation soil, mother earth or the like. In a continuous from bottom to top free space behind a continuously and continuously extending outer skin can be introduced.
  • a further object of the invention is to provide a Erdböschung, in which after creation of the supporting and solidified area to be established at a distance from this area wall of grid mats can be quickly and reliably fixed so that the grid mats form a continuous, continuous surface.
  • Fig. 1 shows the cross section of a Erdböschung, which is composed of a natural, existing Erdböschung 3, in front of the layers of a geotextile reinforced, supporting and solidified area was constructed and before a non-supporting outer skin area 2 is located.
  • the load-bearing and solidified area 1 is composed in this example of five layers 21 - 25 Dritz 4, which is enclosed per layer on three sides by a flexible reinforcing mat 5.
  • the flexible reinforcing mat 5 of each filling bottom layer 21 - 25 has a substantially horizontal lower portion 15, a front vertical portion 16 and a folded-back upper portion 17.
  • Each Artitzlage 21 - 25 is highly compacted by means of vibration rollers or the like, before the next higher layer is constructed.
  • a removable vertical formwork e.g. from chalkboards, attached.
  • the section 15 of the reinforcement mat is folded back and the filled floor is highly compressed.
  • the flexible reinforcement mat and the formwork of the next following layer are mounted so that the embankment receives the desired inclination. This results in steps 14, which are the greater, the smaller the slope angle from the horizontal.
  • rod-shaped spacers 8 are mounted, which protrude over the vertical regions of the flexible reinforcing mats 5 by preferably 10 to 15 cm, so that at them at a distance 36 of at least 10 cm from bottom to top continuous rigid and large mesh grid 7 can be attached.
  • the lattice mat 7 has relatively large lattice openings, then provided with small meshes or openings layer 9 of mesh fabric, wire mesh or fleece on the inside of this grid mat 7 so that between the supporting and solidified area 1 and the rigid grid mat 7 effectively choir floor 10 does not fall through the openings in the grid mat.
  • the spacers 8 can also be driven horizontally or else at right angles to the embankment inclination into the load-bearing and solidified area after the load-bearing and solidified area 1 has been created become.
  • the spacers 8 may be provided with barbs 13.
  • the spacers 8 may have stops 11 for the rigid grid mat. These stops can be adjustable along the rod-shaped spacers 8.
  • the projecting ends of the rod-shaped spacers 8 are provided with a screw thread for receiving and guiding a clamping nut 12, so that the rigid grid mat can be accurately aligned, possibly even after filling the vegetation floor 10th
  • the vegetation soil 10 or a mixture of topsoil, substrate and optionally also seeds with water additions is brought into a pumpable state and pumped into the space between the supporting and solidified region 1 and the outer skin.
  • the drainage of the excess pumped water is filter-stable through the predominantly geotextile mat.
  • the lattice mat which may be a Baustahlgewebematte and may be corrosion resistant by galvanizing or by a plastic coating, as well as the at least 10 cm thick layer of vegetation soil, the flexible textile reinforcement mat of the filler layers 21 - 25.
  • this embankment according to the invention makes it possible that the outer skin can be repaired if necessary, for example after a truck impact.
  • Fig. 2 shows the cross section of a noise barrier, which is planted on both sides and which is constructed according to the method of the invention.
  • the Medbodenlagen 31 - 35 are getting narrower upwards, so that on both sides of the side walls of the wall receive an inclination of about 60 ° to 70 °.
  • Like-acting parts are provided with the same reference numerals as in FIG. 1.
  • a sound barrier is shown in cross-section, in which only one side is planted, while in the other and steeper side between the rigid grid mat 7 and the compacted and textile-reinforced Grezierlagen concrete 18 is filled.
  • concrete 18 instead of concrete 18 but also gravel, gravel or the like pourable material can be filled, if so from landscape, architectural or other circumstances seems appropriate.
