Description

TECHNICAL FIELD [0001] The present invention relates to a core-

More particularly, the present invention relates to a core-type perforation apparatus, and more particularly, to a core-type perforation apparatus having a circular ring-shaped core tube through a core tube having a circular hollow shape during a tunnel blasting operation, To a core-line-type perforation device for allowing noise, vibration, and pulverized materials to be transmitted to the center of the core portion without being transmitted to the outside.

Generally, roads and railways to which vehicles or railways pass are preferably constructed in a straight line toward the destination as much as possible. Therefore, when a mountainous area obstructs roads or railways, a tunnel is excavated for vehicle communication, .

Tunnel excavation methods are various but excavation methods by blasting explosives are widely used.

In other words, in order to excavate the tunnel, the center portion of the tunnel made of rock is first blasted to form a hole, and then a plurality of peripheral holes, outermost holes and bottom holes disposed around the tunnel are blasted, .

In other words, the first thing that must be preceded for tunnel advancement is to drill a hole in the heartbeat to expand the free surface.

In the above-mentioned core portion, a plurality of charge holes and a plurality of armed drug holes are suitably arranged to insert explosives into the charge holes to be blasted. These charge holes are formed in an inclined shape toward the free surface, and then explosives therein are blasted, An angled hole cut to form a hole, and a parallel hole cut method in which a charge hole is formed in a parallel shape toward a free surface and then blasting the explosive therein to form a hole in the deep portion The center pinion of the center pinion is made.

It is difficult to apply to the small cross section because the diameter of each hole is different for each hole. Because it is difficult to drill by using machine, it is mainly used for blasting weathered rock and soft rock. It is easy to mechanized piercing, The law is widely used for the blasting of light rock and extreme light rock.

Recently, road and railway facilities have been rapidly increasing for efficient development of the country, and they are being constructed close to the urban area or the residential area rather than the mountainous area. As a result, the noise, vacuum, and non-product generated by the blasting operation are transmitted to the outside, causing pollution in the surrounding environment and causing various complaints.

In order to solve the above-described problem, the conventional patent registration No. 10-0423567 entitled " Thinning Blasting Method "has been proposed.

This is a method for blasting a plurality of burial holes on a first free surface of a rock bed for drilling an underground cavity or a rock slope and inserting a cylindrical charge holder loaded with explosives into each of the burial holes, Wherein an inclined hole inclined radially with respect to the first free surface is formed in an outer peripheral surface of the charge holder, and when the charge holder is inserted into the charge hole, So that explosive energy can be concentrated on the portion to be excavated along the direction of the first free surface through the inclined hole.

Therefore, since the inclined hole is formed on the outer circumferential surface of the charge holder so as to face the first free surface in the radial direction, the explosive energy generated upon explosion of the explosive loaded in the charge holder is concentrated in the inclined hole. Therefore, the excavating ability at the time of deep shading can be improved, and the quantity of the charged ball and the amount of the explosive to be used can be reduced, and the blasting vibration can be reduced.

However, there is a problem that noise and vibration are largely generated during the blasting operation, as in the previous case. Therefore, when the tunnel is constructed near the residence, many civil complaints are generated, There has been a problem that it becomes difficult.

The present invention has been conceived to solve the above-mentioned problems, and it is an object of the present invention to provide a core tube having a circular shape and having a hollow shape during a tunnel blasting operation, and then a blasting operation is performed through a center or a gap A core line-type punching device which allows noise, vibration, and lumps to be gathered while facing the center of the deep-seated portion, and various sensors are provided to automatically control the perforation position, The purpose is to provide.

According to an aspect of the present invention, there is provided a core-type perforation apparatus (100) including a movable vehicle (200); An angle control unit 300 formed on an upper surface of a front end of the vehicle 200 to control a vertical angle of the front end of the linear motion control unit 400 while providing a linear propulsion force to a bottom surface of the linear motion control unit 400; The linear movement control unit (400) rotating the linear motion of the perforation (500) while the lower end is pivotally coupled to the angle control unit (300); And the perforation 500 formed on the upper surface of the linear motion control unit 400 and perforating a tunnel around the distal end surface of the open mouth while linearly moving.
