Definitions

  • the invention relates to a method for producing a slot wall in the ground according to the preamble of claim 1. Furthermore, the invention relates to a trench wall cutter for producing a Frässchlitzes according to the preamble of claim 4.
  • a generic trench cutter and a generic method are from the JP-A-09273150 known.
  • a miller with a box-shaped frame is sunk to a supporting rope hanging to form a slot in the ground.
  • To guide an upper portion of the slot is provided with guide walls, so as to specify an exact alignment of the box-shaped frame from the beginning.
  • Through a clearance at the end faces of the box-shaped frame milling cuttings and supplied liquid is conveyed past the frame in a rear region of the slot.
  • a second step after the grading of the slot to the final depth curable cement suspension can be introduced into the area of the cutting wheels and mixed by the rotating cutting wheels.
  • JP-A-11200404 From the JP-A-11200404 is a trench cutter with a scaffold-like structured guide frame known. On the side surfaces of the cutting wheels injection nozzles are arranged, through which a cement liquid can be injected under pressure to the outside, so as to widen the Frässchlitz.
  • a particularly long guide frame ensures safe guidance of the mill along the already milled diaphragm walls.
  • From the JP-A-08302670 is a method for producing a trench wall, in which the ground crushed by means of cutting wheels and the crushed soil material is conveyed together with supporting liquid via a pipe to the outside to a processing plant. After separation of coarse material, the liquid is returned to the slot and mixed via separate mixing wheels on the miller.
  • the mill is mounted on a carrier which is constructed of H-shaped cross-section segments. The carrier with the cutter is suspended on a carrying cable.
  • To guide the router in the upper area above the slot a guide frame construction is provided with guide walls.
  • a method for producing a slot wall in the bottom is from DE-C-195 30 827 known.
  • a milling slot is excavated in a first phase and the resulting excavated soil of the milling slot promoted to overground.
  • the resulting milling slot is filled with a support suspension and supported so.
  • a hardening suspension is introduced into the slot while displacing the support suspension.
  • the slot is supported from the beginning by a suspension which is prepared by mixing excavated soil material and a binder overground.
  • the object of the present invention is to provide a method for producing a trench wall in the ground and a trench wall cutter with which a trench wall can be produced efficiently and in good quality.
  • the cleared soil material is conveyed by the cutting wheel into a rear region of the milling slot, that the cleared soil material in the milling slot is mixed with the settable liquid, and that the cleared soil material is at least partially in the Milling slot is left to form the slot wall.
  • a basic idea of the invention is to mix the soil material cleared away from the cutting wheels in the milling slot by the action of the cutting wheels with the settable liquid so to speak "in situ" and thereby to produce a hardening liquid-soil mixture. This eliminates the need to elaborate the entire cleared soil material by pumping equipment consuming to overground.
  • the cleared soil material is conveyed according to the invention of the cutting wheels in a rear region of the Frässchlitzes.
  • the back Area can be an area that is formed in the milling slot above the frame.
  • the mixed with the liquid, cleared soil material is at least partially left in the milling slot, where it can harden to form the slot wall.
  • a discharge device can be provided on the trench wall cutter or surface at the edge of the trimming slot.
  • the cutting wheels In principle, it is possible to drive the cutting wheels uniformly when drilling the Frässchlitzes. However, a particularly good milling action and / or a particularly good mixing of the soil material with the settable liquid can be achieved by reversely driving the cutting wheels. By a temporary reversal of the direction of rotation of the cutting wheel, turbulences are formed in the soil material, which ensure particularly good mixing with the settable liquid.
  • the cutting wheels are also uniformly or reversibly driven when pulling the trench wall cutter from the milling slot, which can significantly reduce the force required for pulling force and additional mixing of the cleared soil material is achieved with the settable liquid.
  • the trench wall cutter can be moved uniformly in the ground. It is particularly advantageous, however, that the trench wall cutter is at least temporarily offset in an alternating upward / downward movement. As a result, a particularly good mixing of the removed soil material with the settable liquid is achieved.
  • the stroke of this alternating upward / downward movement can be significantly less than the total height of the slot. It may in particular be of the order of the diameter of the cutting wheels.
  • Such alternating at least temporarily performed upward and downward movement can be achieved by the trench wall cutter is lifted by a construction equipment and then discharged again. An alternating upward / downward movement can be carried out both when sinking the Frässchlitzes and when pulling the trench wall cutter from the finished Frässchlitz.
  • a trench wall cutter according to the invention is characterized in that the cross section of the frame is smaller than the cross section of the trimming slot to form a clearance through which cleared soil material from the at least one cutting wheel on the frame over in a rear portion of the trimming slot is conveyed.
  • a basic idea of the trench wall cutter according to the invention is to form a free space next to the frame, through which cleared soil material and suspension can flow as unhindered as possible on the frame of the trench wall cutter when producing the trimming slot and / or pulling out the trench wall cutter from the finished trimming slot.
  • This allows a particularly fast and energy-saving milling with a simultaneous efficient mixing effect.
  • the cross section of the frame perpendicular to the direction of advance of the trench wall cutter never completely covers the trimming slot. This is achieved in that the circumferential dimensions of the cross-section of the frame are smaller than the inner dimensions of the Frässchlitzes.
  • one or more openings may be provided in the cross section of the frame. Such an arrangement allows a passage of cleared soil material past the frame in the direction opposite to a direction of movement of the frame.
  • a plurality of cutting wheels are provided in any number, which have parallel axes of rotation.
  • a preferred embodiment has four cutting wheels, two of which are arranged in pairs rotatable about the same axis of rotation.
  • a cross section of the milling slot is preferably rectangular.
  • the at least one cutting wheel has a suitable for a reversing rotary movement Fräs leopardan ever.
  • a Fräs leopardan ever can clear pending soil material in a rotation of the cutting wheels both clockwise and counterclockwise. This allows a particularly good mixing of the soil material with a simultaneously high rate of degradation.
  • a feed device for feeding a liquid, in particular a settable liquid, into the milling slot at an arbitrary position in the milling slot.
  • a feed device is arranged on the frame.
  • a particularly good mixing of the cleared soil material with the liquid is achieved.
  • a slot wall milling device is characterized in that the slot wall cutter is displaceably guided on the carrier device by means of a linear guide device.
  • the trench wall cutter is guided not on the wall of the trimming slot but on a carrier device spaced apart from the trench wall cutter.
  • the guide takes place in particular in a direction parallel to the direction of advance of the trench wall cutter direction.
  • the linear guide device has a guide rod, in particular a telescopic rod, on which the trench wall cutter is mounted.
  • a guide rod allows a particularly good lateral guidance of the trench wall cutter.
  • it also allows a transmission of an axial force directed in the advancing direction from the carrier device to the trench wall cutter, whereby a particularly fast propulsion of the trench wall cutter can be achieved during drilling.
  • the trench wall cutter can also be designed such that it mills into the ground only when its cutting wheels are rotating due to its own weight.
  • a guide rod can be used, which is not designed for the transmission of a thrust direction directed axial force.
  • the diameter of the guide rod is preferably dimensioned to be smaller than the diameter of the cross section of the frame.
  • the guide rod preferably has a substantially rectangular or substantially circular cross-section.
  • a telescopic rod can also be used preferably a Kelly rod.
  • a particularly preferred slot wall milling device is further characterized in that the linear guide device has a guide sleeve arranged on the carrier device, through which the guide rod is guided.
  • a guide sleeve can surround the guide rod wholly or partially in the circumferential direction.
  • projections and / or depressions may be formed, which engage with corresponding recesses and / or projections on the guide rod and thus ensure a rotationally fixed guidance of the guide rod.
