Desliming device null of road widening excavation

摘要

PROBLEM TO BE SOLVED: To increase the capacity of slime-removing equipment by moving up or down a treatment device equipped with a slime-suction means moving around in the widened breadthwise direction through a guide in the guide groove for excavating the breadth. ;SOLUTION: A slime-treatment device B constituted of a frame body 14 equipped with a slime-suction part S which is movable breadthwise, is equipped in a guide member 13 erected in a guide groove 10 to widen the breadth for excavating the position right under an obstacle U in the underground. And the device B is hung down by a crane 16 to freely rise and fall. A slime-suction opening 18 having a size corresponding to the excavation part 17 for the widened breadth and a delivery pipe 21 having a slimetreatment part 20 connected to a suction pump 19 are fitted to the arm 22, in the slime-suction part S. The slime-suction opening 18 can be freely turned to any required positions of the excavation part 17 by a hydraulic cylinder 24. Slime C sucked up by the suction pump 19 through the delivery pipe 21 is sent to a soil separator and treated therein. In this way, slime can be securely removed and the cut-off function of a continuous underground wall can be improved and the cost can be reduced.;COPYRIGHT: (C)1999,JPO
