ABSTRACT:
The invention is concerned with civil engineering. It relates to a system for guiding the excavation tool used for making the trenches necessary for the construction panel-by-panel of a wall cast in the ground, which comprises, in combination, a vertical guide member extending over the height of the trench to be made and fixed to the adjacent panel or to a formwork located at the end of the adjacent panel, and guide wheels mounted on the excavation tool and rolling on the said member, said guide wheels being retained positively by the guide member relative to any horizontal force tending to separate them, and some wheel being profiled so as to be capable of destroying any obstacle of hardened concrete present on the guide member.
