The perforated body 120 according to the present invention comprises a fixing portion 121 and a rotation portion 122 fitted to the outside of the fixing portion.

The fixing portion 121 is formed in the shape of a pipe having a long length and has a through hole (through hole of the fixing portion, 121-H) formed therein in the axial direction. The front end of the fixing portion 121 has a front side injection nozzle (121-N) are formed. The front side injection nozzles are spaced apart from each other such that water can be radiated.

When the rotation unit is rotated, water pressurized by the side injection nozzle is injected. In other words, the water pressurized from the injection nozzle is not sprayed when the rotating part is not rotating.

Referring to FIG. 3, the pressurized water passes through the through-hole 121-H of the fixing portion 121 and is injected to the front side injection nozzle 121-N of the fixed portion. Further, the pressurized water is injected to the side injection nozzles 122-N of the rotating portion through the through holes 122-H of the rotating portion 122.

Hereinafter, a method of cutting a rock by using a rock punching apparatus constructed as described above will be described. 5 to 7 are views for explaining cutting a rock using a rock punching apparatus according to the present invention.

According to the present invention, there is provided a method for cutting a rock, comprising the steps of: forming an insertion hole having a predetermined depth in a rock plate by advancing a perforated body while spraying water with a spray nozzle of a fixed portion; A second step of forming an annular hole by spraying water from an injection nozzle of the rotary part while rotating the rotating part of the perforated body, a third step of retracting the perforated body when the cutting hole having the insertion hole and the annular hole is completed, A fourth step of forming at least three or more cutting holes so as to have a shared area where the annular holes overlap each other at a predetermined distance from the cutting hole and a holding area where the annular holes do not overlap each other; And a fifth step of crushing and removing.

5 is a view illustrating the formation of one cutting hole in a rock by using the rock punching apparatus according to the present invention.

Referring to FIG. 5 (a), the perforated body of the rock punching apparatus is positioned on the side of the rock, and the pressurized water is injected from the injection nozzle of the perforated body fixing unit. An insertion hole is formed in the rock plate by the water to be sprayed. When water is subsequently injected into the insertion hole, the insertion hole becomes deeper as shown in Fig. 5 (b). The depth of the insertion hole may be a preset depth in the controller.

When the insertion hole is completed at the predetermined depth in this way, the controller stops spraying the water.

Thereafter, as shown in Fig. 5 (c), the injection of water starts at the rotating portion fitted to the outside of the fixing portion. When the pressurized water is injected from the rotating rotary part, an annular hole is formed in the rock in the lateral direction at the end of the insertion hole. Such an annular hole may be formed with a predetermined radius in the controller.

Finally, when the annular hole having the predetermined radius is completed, the controller retracts the puncturing member from the insertion hole (see Fig. 5 (d)).

When all of these processes are completed, one cutting hole VHH made up of the insertion hole VH and the annular hole HH is completed.

FIG. 6 is a side view of cutting a rock using a rock punching apparatus according to the present invention.

6 shows a view of the rock as viewed from the front. A plurality of cutting holes as previously described with reference to FIG. 5 are formed on the entire surface of the rock. At this time, after forming one cutting hole, neighboring cutting holes have a common area SHA. In other words, the annular hole of one cutting hole and the annular hole of the adjacent cutting hole have an overlapping area. The one cutting hole and the adjacent cutting hole set the positions of the neighboring cutting holes so as to have the non-overlapping holding areas SUP.

According to the present invention, at least three neighboring cutting holes having one cutting hole, the shared region, and the holding region can be formed.

When all the cutting holes are formed on the entire surface of the rock, the rock slice separated by the holding region is formed on the entire surface of the rock with respect to the holding region. Thereafter, the separated rock slice is crushed by using a hammering means such as a hammer.

The process of forming such a cutting hole and crushing the rock slice can be progressed in order to crush the rock mass.

A rock punch boring apparatus according to another embodiment of the present invention includes a body, a drill body provided with a position adjustable from the body, a striking unit that reciprocates linearly and swivels, and a rotating unit that injects pressurized water, And a controller for controlling the position of the perforated body, the striking unit, and the rotating unit, which are installed in the body.

The drilled body of the rock piercing apparatus according to another embodiment of the present invention has the same rotary part and a striking part instead of the stationary part in comparison with the above-described embodiment.

The striking portion of the drilled body includes a cylinder provided inside the rotating portion, and a drill head that performs a linear reciprocating motion and a rotating motion in the cylinder. Referring to the drawings, a fin is provided at the tip of the drill head. The fin is formed of a hard metal material, and functions to break the rock at the tip. The piston provided at the rear end of the drill head moves in the cylinder, and the piston transmits the impact energy PRS to the drill head by compressed air or hydraulic pressure.

A controller according to another embodiment of the present invention includes a position controller driving module, a striking part control module, a rotating part driving module, a rotating part water supplying module, and a switcher.

Here, the striking part control module controls the driving of the striking part of the striking body. For example, compressed air or hydraulic pressure for linear reciprocating motion and rotational motion of the striking portion. The switching unit switches the driving of the hitting unit and the rotating unit. The rotation unit configuration module and the rotation unit water supply module of the controller according to another embodiment of the present invention perform the same functions as those of the embodiment described above.

The crushing of the rock by using the rock punching apparatus having the perforated body constructed as described above is as follows.

An insertion hole having a predetermined depth is formed in the rock by using the striking portion. At this time, the drill head of the striking portion transmits a linear reciprocating motion and a rotating motion to the rock to form a predetermined hole in the rock to form an insertion hole.

When the insertion hole having the predetermined depth is formed, the impact portion is stopped, and water is sprayed from the nozzle of the rotating portion while rotating the rotating portion to form an annular hole having a predetermined radius. When one cutting hole is completed, the perforated body is retracted from the insertion hole.

Then, at least three cutting holes are formed so as to have a shared area where the annular holes are overlapped with each other and a holding area where the annular holes do not overlap each other at a predetermined distance from one cutting hole. Subsequently, when a plurality of cutting holes are completed, the separated rock slice is crushed and removed at the front side of the annular hole.
