[origin: US5707182A] PCT No. PCT/EP94/00671 Sec. 371 Date Nov. 8, 1995 Sec. 102(e) Date Nov. 8, 1995 PCT Filed Mar. 7, 1994 PCT Pub. No. WO94/21864 PCT Pub. Date Sep. 29, 1994A process for exactly holding the vertical excavation direction of a diaphragm wall using a hydraulic diaphragm wall grab cooperating with an excavator and having an outer guide body and an inner body for receiving the grab appliance is improved and rendered considerably more efficient by the fact that the vertical position of the inner body and/or the guide body is continuously controlled by means of an inclination detector whose-signals are transferred to a controller which, in case the bodies of the grab deviate from the predetermined vertical position, compensates said deviation by swivelling the inner body relative to the guide body in opposite direction to the deviation.
