PROCESS FOR GUIDING THE EXCAVATION TOOL USED FOR THE CONSTRUCTION OF A WALL CAST IN THE GROUND, AND EXCAVATION TOOL FOR IMPLEMENTING THIS PROCESS

摘要

The invention relates to a method for guiding the digging tool used to dig the trenches necessary for forming, by successive or alternate panels, a wall cast in the ground, characterised in that : … …  a) a digging tool (4) equipped with a first guiding means (5) is provided, …  b) a second guiding means (3) is arranged at the end of a previously dug trench, which extends substantially over the whole depth of this trench; then …  c) the guiding means are engaged after the panel (1) has been formed in the previously dug trench; and …  d) the digging tool is controlled so as to create a force which tends to keep the guiding means mutually engaged while the next trench is being dug. … …??Use in the civil engineering field …IMAGE…
