System for underground vertical sealing wall construction

摘要

The construction system involves the crossing strips, of the sealing wall to be erected, being stepped out on the wall's axis at definite intervals. Barrier walls (a) are inserted into the transverse plates (m). The sections between the crossing strips are raised by means of claws or cutters (f) in an interlaced, woven sequence. The raised masses are used again to fill the sections and the number of plates between the crossing strips is variable.
