Definitions

  • the invention relates to a method for producing a floor concrete wall and a device for performing the method.
  • the invention has for its object to provide a method and an apparatus for producing a floor concrete wall, with which defined limited wall structures in the floor can be produced in an integral design.
  • a tubular body which has longitudinal vertical lines is first introduced into the ground.
  • Compressed material is introduced into the soil material contained in the pipe body via the pipes under pressure.
  • the pressing direction can be selected from bottom to top as well as from top to bottom.
  • the lines are supplied with compressed air as support. This compressed air exits into the interior of the tubular body in the lower area and loosens the soil in it. The loosening is done pneumatically and not by mechanical stirring tools.
  • the tubular body can have any cross section. It can be round or angular.
  • the tubular body is preferably an elongated box with a horizontal length of up to approximately 3 meters, a vertical height of several meters and a horizontal width of the thickness of a conventional wall, that is to say a maximum of approximately 50 cm. This box is on open at the top and bottom and preferably sharpened at the bottom to better penetrate the ground.
  • the tubular body is preferably introduced into the ground by shaking with a vibrator which is attached to the upper end of the tubular body and exerts vertical vibrations.
  • the method according to the invention is particularly suitable for non-cohesive coarse-grained and mixed-grain soils and for sand-silt mixtures. It enables the production of defined concrete walls without uncontrolled side breaks.
  • the lines can be used simultaneously for the supply of compressed air and the supply of suspension. However, it is also possible to use different lines for the material to be pressed than for the compressed air.
  • the injection material can be supplied in powder form or as a suspension. Generally suitable as a suspension are curable mixtures, in particular cement suspension or bentonite.
  • a tubular body 10 is inserted into the floor.
  • the tubular body 10 consists of a box-shaped body with a horizontal length of approximately 3 meters, a vertical length of approximately 15 meters and a width of approximately 40 cm.
  • the representation in the drawings is not to scale.
  • the box-shaped tubular body 10 is open at its upper end 11 and at its lower end 12. At the lower end 12, the walls have sharpenings 13 which facilitate penetration into the ground.
  • the interior 14 of the tubular body is empty.
  • the tubular body consists of a welded steel structure.
  • Vertical conduits 15 run on the inner sides of the walls and extend essentially over the entire height of the tubular body.
  • the lines 15 are tubes or hoses which lie closely against the walls of the tube body.
  • connection couplings 16 for supplying a medium to the lines.
  • the lower ends of the lines 15 lead to outlet nozzles 17 which are directed into the interior 14.
  • the outlet nozzles 17 are arranged at a distance of at least about 30 cm from the lower end 12 of the tubular body.
  • the lines and nozzles on the two opposite walls of the tubular body 10 are in each case offset from one another, so that each outlet nozzle 17 sprays into the area between the outlet nozzles of the opposite wall.
  • the lines 15 on both opposite walls are offset from one another.
  • FIG. 4 shows the lowering of the tubular body 10 into the bottom 19.
  • a vibrator 20 is attached to the upper end of the tubular body 10.
  • the vibrator is suspended from a carriage 21 which can be moved on a mast 22 of a crawler vehicle 23.
  • the vibrator 20 consists of a drive part 24 and a vibration part 25 arranged underneath.
  • the drive part 24 contains one or more motors and the vibration part 25 contains eccentric masses which rotate about a shaft and generate vertical vibrations.
  • gripping tongs 26 are provided which grip and clamp the vertical end walls of the tubular body 10. The introduction of the tubular body 10 into the ground takes place under the weight and the vibrations of the vibrator 20.
  • compressed air 27 and hardenable suspension are supplied through the lines 15 according to FIG. 5, which exit from the outlet nozzles 17 into the interior 14 .
  • the compressed air supports the mixing of the soil with the injection material. It creates buoyancy and a reduction in wall friction, so that propulsion is accelerated.
  • Compressed air and Suspensions can also be fed into separate lines 15.
  • Figure 6 shows the state that the tubular body 10 has reached the intended depth. Then, liquid or powdery injection material 29 is further fed through the lines 15. Mixing the injection material with the soil material creates a viscous mass that does not leak into the surrounding soil. During the injection of the concrete, the tubular body 10 is withdrawn, whereby the vibrator 20 can function to reduce the frictional resistance and to compact the soil concrete.
  • FIG. 7 shows a pipe clamp 30 with which the line 15 is fixed to the wall of the tubular body 10. Such pipe clamps can be welded to the inner wall of the pipe body at the required intervals.
  • FIG. 8 shows a line 15 which runs on the outside of the tubular body 10 and is protected there by a shoe 31 welded to the tubular body.
  • FIG. 9 is a section through an outlet nozzle 17 which is connected to a line 15.
