Abstract

PURPOSE:To improve the efficiency by suspending in a pair of longitudinal holes so as to make possible to move vertically, pushing and fixing the inside wall by radial extension of the gripper frames and constituting of a pair of machine bodies capable of moving vertically, a coupling beam and a chain cutter. CONSTITUTION:The gripper frames 15 are suspended in a pair of longitudinal holes 1 so that they can be vertically moved by a crane 16, and they are pushed and fixed to the inside wall 20 by a plurality of hydraulic cylinders 30 radially provided to the perimeters of the rings 15(a) so that they are capable of extrusion and contraction. A machine body 21 is constituted of the upper and lower cylindrical guide rods 22 and is so provided that it is vertically free against the rings 15(a) by a slider, and it is slid vertically against the gripper frames 15 by a hydraulic cylinder on the ground. A coupling beam 24 and a chain cutter 25 are joined respectively between a pair of machine bodies 21, and by circulating and rotating them the earth layer 2 between the longitudinal holes 1 is excavated. Accordingly, the earth moving volume can be reduced.
