Abstract (en)
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>
