Definitions

  • the invention relates to a method for Stabilizing a floor for a traffic route, like a Road or a railway line, with one being Soil cultivation device in the path direction at least a grave-shaped path by loosening the soil material and Mixing it with a stabilizing agent is processed, whereby in the direction of a reinforced track Bottom wall is formed.
  • Such a method is from the German patent application 195 42 031 and Dutch Patent Application 1010451 known.
  • Using such a procedure can be opposite a conventional, time consuming process with a poured sand bodies in areas with less load-bearing Soil like loam / peat soil relatively quickly becomes a traffic route be formed.
  • a heaped sand body requires a long settlement wait before the road can be completed while rest relative require a lot of maintenance.
  • With bottom walls can a Not only be completed faster, but it also creates a low-setting Construction and thus a reduction of the required Maintenance work.
  • Stabilization through the bottom walls is achieved by dissolving the dissolved soil material with the Stabilizing agent whose main component is cement, mixes, and its volume according to the Dutch Patent Application 1010451, for example 10 to 25% of the volume may amount to the dissolved soil material. After mixing Therefore, the volume of the mixture is greater than the volume the trench-shaped path. The additionally formed volume becomes removed as excess material, including in the Device according to Dutch Patent Application 1010451 a special discharge system attached to the mixing chamber has been. After the completion of the floor walls extend these, as indicated in German Patent Application 195 42 031, in Path direction under the path to be created or the to be created railway line.
  • Embodiment will further be a construction for Wearing a lane with two lanes and one Hardening width of 7.5 m discussed, including in Path direction four bottom walls are attached and actually the talk of a compound, monolithic, reversed U-shaped bottom profile is. Because of Short version will continue to receive the various Forms of execution of the floor profiles as tunnel profile designated.
  • the leveled layer be protruding extends past an outboard bottom wall. Then In each case a bottom wall would be mainly vertical under an expected lane of a wheel loading the road extending over the road vehicle.
  • the Attach the bottom walls to a subfloor of a layer of sand attached which in the processing of the leveled Layer at least partially with the leveled layer is mixed. So is a particularly intense, as well Controlled connection of the leveled layer with the upper ends of the bottom walls, which are initially in the Sand layer enough to realize and thus optimal Load capacity for the tunnel profile.
  • the formed tunnel profile is provided that on a monolithic construction thus obtained, consisting from at least two bottom walls and one, this at their upper ends connecting and covering layer, more Cover layers are attached.
  • the construction shown in the simple figure forms a two-lane road with a complete hardened width of about 7.5 m and to the opposite Sides a half-hardened roadside of about 2 m.
  • a complete hardened width of about 7.5 m and to the opposite Sides a half-hardened roadside of about 2 m.
  • the So soil dissolved in a trench-like orbit will then, for example, ah different injection sites along the Framework, a stabilizer added in suspension.
  • Main component of the stabilizing agent forms For example, cement, but also any other suitable Additive or a combination of materials.
  • the Shape of the paddle wheels is still chosen so that not only the soil material is dissolved, but also dissolved Soil material and stabilizer added intensively be mixed.
  • a mixing amount is obtained which is greater than the soil dissolved in a trench-like path. If the additional amount obtained, which can not be accommodated in the bottom wall 3 and thus emerges from the subfloor formed by the sand layer 2, is about 20%, this means that in the present case an excess of about 2m 3 / m road is formed , This excess is distributed over a width of 11.5 m, ie the intended roadway with semi-hardened roadside, which results in a leveled layer 4 with a thickness of about 170 mm. On this leveled layer 4, a sand layer 5 is then applied to a height of about 300 mm above the original top of the earth 1.
  • the resulting layer structure with a height of approx. 500 mm is shown in the left part of the simple figure. These layers are using a roller cutter with each other mixed. Under a rotary mill we understand one Soil cultivation device, with the at least one horizontal material layer intensively mixed and can be homogenized.
  • the bottom walls 4 with their upper ends to the sand layer 2 and are therefore at Editing the layer structure with the tiller taken, so that the obtained, intensively mixed, horizontal layer 6 (see the right part of the simple figure) after the Curing together with the bottom walls 4 a one-piece, strong, torque-stable, stable and stable monolithic Basic body forms, consisting of a horizontal, stress-distributing layer, that of four, one unit thus forming vertical stress distribution layers is supported.
  • the width of 11.5 m in the Generally not in a single time with a roller cutter, which is moved in the direction of the train, can be edited.
  • the mixer or Stabilization process is then commonly found several tracks instead.
  • the positions of the Bottom walls 4 in terms of overlap between different tracks an important focus, in particular Such an overlap preferably does not have to be at the Place a bottom wall 4 are located.
  • the bottom walls seen in the direction of the line one of have a different shape from a flat plane for example, zigzag or wavy stretch.
  • the number of floor walls under the entire Traffic not always be the same. So, in places over a certain distance one or more additional Floor walls are being built.
  • depth and thickness of the Floor walls vary with each other or in the path direction. This also applies to the thickness and width of the bottom walls flattened to a one-piece tunnel profile Layer that can also project beyond the outermost floor walls or not.
  • the overhanging can also be one-sided and the Width of the overhang can be along the road to change.
