Abstract (en)
[origin: EP0791690A1] In a device for adjusting inclination of an excavating head for constructing concrete underground walls, a plurality of movable surfaces are mounted to the excavating head (3) so as to be selectively urged against the walls of the excavation. Said surfaces are comprised of a pair of rigid, substantially vertical guides (4, 5) mounted on two opposite vertical sides of the excavating head. The guides have bottom portions linked (8, 9, 15, 16) so as to accomplish rotation in a respective vertical plane by means of upper actuators (10, 11). <IMAGE>
