Abstract
A drilling method and device is for the execution of diaphragm walls by cutters, (131, 105, 110) carried by a frame (130) supported by suspension and movers (102). A guide hole (200) is formed as far as the depth specified in the design at the center of the panel to be made. Excavation is started with the introduction into the guide hole (200) of a guide element (101) that is fixed with respect to the tool-holder frame and having geometry such as to copy the guide hole along which it slides during excavation. Excavation is carried out as far as the depth specified in the design. The tool is extracted from the excavation and the excavation is filled with concrete and a panel is formed. The method is repeated so as to form adjacent panels.
