摘要

A method for making a trench wall in the ground, with the– at least one to a frame (20) of a trench wall cutter (10) which is arranged in the cutting wheel (12, 12 '') by means of a drive (15, 15'') is set into a rotary motion,– the trench wall cutter (10) with the frame (20) is lowered into the soil, which below the cutting wheel (12, 12 '') located in the soil material removed and a cut trench (3) is produced, and– the cut trench (3) is filled with a settable liquid,characterized by the,– that the settable liquid on the frame (20) in the cut trench (3) is initiated,– that the stripped soil material of the cutting wheel (12, 12 '') in a targeted manner in a rear area (4) of the cut trench (3) is conveyed,– that the stripped soil material in the cut trench (3) with the settable liquid is thoroughly mixed and– that the stripped soil material at least partially in the cut trench (3) is left to form the trench wall.
