Definitions

  • the invention relates to a method for producing a Foundation element in the ground according to the preamble of the claim 1.
  • a tillage implement through which soil material is loosened, in introduced a soil area, the dissolved soil material in the floor area with a liquid to a settable Suspension mixed and the suspension in the bottom area too solidified the foundation element.
  • the invention further relates to a device for manufacturing a foundation element in the ground according to the preamble of Claim 6.
  • a device for manufacturing a foundation element in the ground according to the preamble of Claim 6.
  • Such a device has a soil tillage implement for loosening soil material in a floor area on, and a feed device for feeding a Liquid to the dissolved soil material and a mixing device for mixing the loosened soil material in the soil area with the liquid to form a settable suspension.
  • DE 198 25 169 C2 describes a device for mixing known from a curable binder in the soil.
  • This known device has mixing blades attached to a shaft for cutting open soil material and for mixing the Floor material with the curable binder.
  • the invention has for its object to provide a method and an apparatus with which particularly high-quality foundation elements can be produced.
  • a method according to the invention is characterized in that that before solidifying suspension from a first section the bottom area is removed and that at least part of the removed suspension in a second section of the floor area is conveyed back.
  • a basic idea of the invention is part of the Bottom area mixed suspension at a tapping point to be removed and at least partially again at another point to return to the floor area. This can cause sedimentation counteracted and an exact suspension mixture be generated. It can be a particularly high quality Create foundation element.
  • the removed suspension is processed before being returned becomes.
  • processing can in particular be a separation a solids content and / or a supply of Include substances to the suspension.
  • Advantageously desanding was carried out during processing.
  • solid particles that have a certain particle size to cut below and / or exceed.
  • the severed Solid content can be used in other construction projects to be collected.
  • the discharge and return of the suspension becomes continuous, in particular carried out simultaneously. hereby eliminates the need for expensive storage facilities to be provided for the removed suspension.
  • the process according to the invention is preferably carried out in such a way that that at least a rising height of the suspension in the floor area is kept approximately constant. In particular, this can prevents the suspension from overflowing from the floor area become.
  • the method can preferably be carried out in this way be that the volumetric flow of the transported suspension at least approximately the sum of the volume flow the returned suspension, the volume flow of the liquid and the volume change in the floor area due to the bringing down or pulling out the tillage implement.
  • the climbing height in the tillage area is preferred recorded via a known measuring device and the outflow of suspension and the inflow of suspension and liquid from or into the floor area for maintenance the climbing height is controlled by electronic control.
  • the first and the second section of the Bottom area can be arranged as desired. Particularly preferred however, it is the first section of the floor area arranged above the second section of the floor area is. This results in a particularly effective mixing of the Allows suspension in the floor area. Is particularly preferred it, the suspension immediately below the rise the suspension in the bottom area. It is also advantageous the suspension to be returned with the liquid to mix and the resulting mixture in the first Promote section of the floor area. With such an arrangement can be the effort related to supply and discharge lines be significantly reduced.
  • An inventive device for producing a foundation element in the soil is characterized by a Removal device for removing suspension from a first section of the floor area is provided and that a return device for returning at least one Part of the removed suspension in a second section of the floor area is provided.
  • Discharge device and the return device according to the invention there may be a circulation of suspension in the bottom area can be achieved, which is a particularly good mixing of the Suspension.
  • a device according to the invention can be used in particular to carry out the method described above come into use.
  • the device is characterized in that the removal device has a suction line in an upper section the floor area is arranged.
  • the suction line preferably has a Suction opening, which is immediately below the rise of the Suspension is arranged in the floor area.
  • the discharge device but can also have overflow trenches in the suspension if a level is exceeded, only drains away due to gravity.
  • the return device is formed together with the feed device.
  • the feed device can be a mixing device for mixing the returned suspension with the liquid supplied as well a common feed line for feeding the resulting Mixture is provided in the second section of the floor area his.
  • the mixing device is preferably outside the Floor area arranged. This can take the effort into account be further reduced to the cable routing.
  • a processing device for processing suspension provided before the return.
  • a processing device can in particular filter, sieve or sedimentation devices to separate a solid part from the Have suspension and / or feed device for additives.
  • the soil tillage implement can be any "Mixed-in-place" device.
  • the device according to the invention is characterized in that the soil tillage implement has at least one Has drill string with a auger and that the Mixing device arranged on the drill string mixing paddles having. Preferably, several, in particular three, are Drill strings arranged in parallel.
  • Such a device allows a particularly simple, fast and inexpensive Manufacture of foundation elements.
  • An outside of the floor area is also preferred arranged drive for rotating the drill string intended.
  • a drive of the soil tillage implement but can also be provided in the floor area.
  • the tillage implement can then be rotatably driven with clearing wheels have clearing tools arranged on the circumference.
  • a soil tillage implement 10 which has a auger 12 and mixing paddles 18 which on one Drill string 14 are attached.
  • the tillage tool 10 loosens soil material in a cylindrical bottom area 6 of the soil 5.
  • Suction line 31 is provided, which in a surface near area opens.
  • the removed material becomes one Processing device 40 feeds.
  • a discharge line leads from the processing device 40 41 for the removal of separated solid and / or liquid and a return line 35 for returning processed Suspension 20 in the bottom area 6.
  • the return line 35 combines with a liquid line 37 for supply of liquid in a supply line 33.
  • the supply line 33 runs inside the drill string 14 and opens at the bottom End of drill string 14 in an exit opening.
  • the volume flows of removed suspension, of prepared suspension and of liquid are through valves 32, 36 and 38 or directly controllable by controlling the respective pumps.
  • the directions of the volume flows in the lines 31, 35, 37 and 41 are indicated in Fig. 1 by arrows.
