By operating the sieve hydraulic jack 22 to make the whole drilling means 20 separate from the surface of the rock, it may be by a sequential retraction method, and each of these hydraulic jacks 23 and the perforated hydraulic jack 22 are simultaneously operated. It may be operated by a simultaneous retraction method in which the retraction of the perforating rod 26 and the retraction of the perforating means 20 are performed together.

19 shows a step of positioning the crushing means 30 in the perforation hole (H) by rotating the rotating arm crushing device of the present invention by 180 degrees with the central tube body 11 as the central axis.

Since the distance between the central peak 14 and the punching rod 26 and the distance between the central peak 14 and the crushing rod 36 are the same, the rotation means 40 installed at the rear end of the central tube body 11 is operated When the rotating arm crushing device is rotated 180 degrees, the crushing rod 36 is accurately positioned in the perforated hole (H).

20 shows a step of moving the entire crushing means 30 forward.

In this step, the tip of the crushing rod 36 is precisely positioned in the perforation hole H by fixing the tip of the integrated crushing means 30 close to the surface of the rock.

To this end, by operating the crushing body moving hydraulic jack 32 fixedly installed in the central tube body 11, the crushing tip fixing plate 31A that integrates the crushing body support guide rod 39 and the crushing guide rod 38 is moved forward as much as possible. The distal end of the crushing rod 36 provided with the crushing protrusion 37b is exactly aligned with the perforated hole (H).

21 shows a step of protruding the crushing protrusion 37b of the crushing rod 36 to expand the perforation hole H to cause cracks or breakage in the rock.

First, by operating the hydraulic crushing jack 33 fixed to the crushing guide rod 38, the crushing rod 36 is inserted into the perforation hole (H). When the insertion of the crushing rod 36 into the perforation hole (H) is completed, the crushing power body 34 is operated so that the crushing projection 37b is hydraulically protruded from the projection groove 37a provided in the crushing pipe 37. make it Accordingly, the inner surface of the perforated hole (H) is pressed or expanded to cause cracking or crushing.
