METHOD FOR MAKING A TRENCH WALL IN THE GROUND, TRENCH WALL CUTTER AND TRENCH WALL CUTTING DEVICE

摘要

The invention relates to a method for making a trench wall in the ground, in which at least one cutting wheel located on a trench wall cutter is given a rotary movement by a drive. The trench wall cutter is lowered into the ground and soil material below the cutting wheel is stripped and a cut trench made, which is filled with a settable liquid. The stripped soil material is conveyed from the cutting wheel into a rear area of the cut trench, that the stripped soil material in the cut trench is intermixed with the settable liquid and that the stripped soil material is at least partly left in the cut trench for forming the trench wall. The invention also relates to a trench wall cutter and a trench wall cutting device.
