Specification

This application of the BAUER Trench Cutter technique in the construction of deep diaphragm and cut-off walls offers advantages over the conventional grab technique in the following key area.

The cutter continuously removes soil from the bottom of the trench, breaks it up and mixes it with a bentonite slurry in the trench. The slurry changed with soil particles is pumped through a ring main of hose pipes to the desanding plant where it is cleaned and returned into the trench. The process of installing reinforcement and placing concrete, soilcrete or grout for a cut-off wall is similar to that with grab techniques.
