PROBLEM TO BE SOLVED: To provide a moving method for an excavator on a mold, smoothly moving the excavator even in the case of a rugged slope, simplifying equipment to be used, and easily installable and removable. SOLUTION: A grid-like pipe 3 is laid on the face of the slope mold 1, the excavator 11 is placed on a sledge-like frame 5, and the sledge-like frame 5 is vertically slid on the grid-like pipe by the drive of a winch, thereby moving the excavator 11 to a required drilling position. At the time of constructing the slope mold, the grid-like pipe 3 is fixed to the slope mold 1 by a fixing rope 4 previously fitted to the frame part near the point of intersection. In order to obtain the reaction force in drilling of the excavator 11, the sledge-like frame 5 is fixed to the slope mold 1 by the fixing rope 4. COPYRIGHT: (C)2008,JPO&INPIT
