Abstract: A device for supporting and guiding supplying lines used with a digging tool on a drilling machine is described. The device comprises a support branch, formed by a plurality of spacers, adjacent to one another in which a rope or tie-rod is inserted in a housing comprised in the spacers, a supplying pipe for the supplying line and a crosspiece comprising a seat adapted to support the supplying pipe. Each pair of adjacent spacers comprises retaining means. Each retaining means comprises a retaining element, associated to a first spacer of a pair of adjacent spacers, and a slot having a shape substantially matching the shape of the retaining element, associated to a second spacer of the pair of adjacent spacers. A retaining element, during use, engages with a slot allowing relative axial movement, in the longitudinal direction of the rope, of a predetermined amount.

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.
