Rock Crushing Unit for Cylinder Packer {BEDROCK CRUSHER INSTALLED IN CYLINDER TYPE PACKER}

The present invention relates to a rock crushing unit installed in a cylindrical packer, and more particularly, a rock crushing unit is installed at the end of a cylindrical packer to press the edge of the rock and cut the side rock by tension force at the same time. It relates to a rock crushing unit installed in the cylindrical packer for removing the.

In general, in order to crush rock for civil engineering or building construction, it is necessary to form blast holes in the rock and put them into explosives into the blast holes to explode, or in the case of special rocks, the method of crushing rocks directly from the outside using a machine according to the rock texture.

And, in the case of rock crushing by a machine or manpower, there is a problem that the progress of rock crushing work is significantly lowered than the blasting method and the constraints of the actual working environment are severe.

In order to solve the problems of the above blasting method, mechanical excavation method, manpower excavation method, a vibration-free, noise-free rock crushing method appeared to cut the rock from the inside by injecting an expandable material after forming a perforation in the rock.

The vibration-free and noise-free rock crushing method is a method of cutting a rock by injecting water or air into the perforation and applying a hydraulic pressure to the wall of the inner perforation by generating a plurality of perforations of a certain depth in the rock.

This vibration-free and noise-free rock crushing method can cut only the necessary parts without indiscriminate cracking of the rock, so it is not affected by rock strength and has an advantage of significantly reducing vibration and noise.

However, in the case of cutting the rock by injecting the expandable material as described above, it is difficult to break the rock when the hole is drilled irrespective of the grain of the rock, or when the hole is drilled in the high-strength rock without the grain. There is a problem that the efficiency is very low.
