To mount the guide rail 10 on the guide rail mounting block 74, as shown in FIG.
The holding part 74a is formed in the same L-shape as the angle of the guide rail 10 and both ends are bent in a hook shape. The holding part 74a has an angle support bolt 74b for fixing the guide rail 10 on a vertical side. I have. The guide rail mounting block 74 is provided with the horizontal rail 6.
A fixing bolt 74c for fixing to zero is screwed. FIG.
As shown in the figure, 41a is a shoe of the underframe 41,
, An excavator 40 is erected. This excavator 40 is the same as that of the embodiment shown in FIG. 1, but in FIG. 7, a pipe mounting 41 d for drilling is fixed on the underframe 41, and the excavator 40 is It can be moved in the longitudinal direction. The guide rails 10 and 10 need not be angles as in this embodiment, but may be grooves or other shapes. However, the shape of the holding portion 74a needs to be configured to match the guide rail.

Although the shoe 41a has a structure in which both ends of a circular pipe are bent upward, the shoe 41a may have a rectangular cross section or another shape as long as it can slide along the guide rails 10, 10. Reference numeral 30 shown in FIG. 7 is an excavator fixing device, and its structure is the same as that shown in FIG. In order to move the excavator 40 vertically along the guide rails 10 between the mountain side and the valley side, and to move the guide rails 10 along the horizontal rail 60, A winch 50 (manual or automatic) is mounted on the mountain side.

The end of the rope 51 extended from the winch 50 is connected to a pair of shoes 41a, 41a as in FIG.
The excavator 40 is mounted on the mountain side of the
Move up and down along 10. When the excavation position is moved in the lateral direction, as shown in FIG. 9, the pulley 52 is fixed to a predetermined position on the guide rails 10, 10, and the end of the rope 51 is passed through the pulley 52 to one of the protective frames 1. The guide rails 10, 10 are moved laterally by operating the winch 50 while the excavator 40 is moved laterally at the same time.

In this case, the pulley 52 is connected to the guide rails 10,
When the mounting position is moved in the longitudinal direction of the guide rails 10 and the guide rails 10 and 10 are moved in the horizontal direction in several times, the guide rails 10 and 10 can be moved smoothly. When the guide rails 10 are moved, the guide rail mounting block 7 shown in FIG.
In the case where the angle supporting bolt 74b and the fixing bolt 74c of 4 are loosened and drilling is performed by the excavator 40, both are tightened together and the excavator fixing device 30 (FIG. 7) is tightened.
