  • a method for producing a slot wall in the bottom is from DE 195 30 827 C2 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 second phase after sinking the Frässchlitzes 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.
  • 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 rope.
  • To guide the router in the upper area above the slot a guide frame construction is provided with guide walls.

  • the at least one cutting wheel is driven uniformly or reversibly also when pulling the trench wall cutter from the Frässchlitz, 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 in or next to the frame, through which cleared ground material and suspension when producing the trimming slot and / or when pulling out the trench wall cutter from the finished trimming slot as unhindered as possible can flow past the frame of the trench wall cutter.
  • 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.
  • the peripheral dimensions of the cross section of the frame are smaller than the inner dimensions of the Frässchlitzes and / or that one or more openings are 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.
