The present invention relates to a thermite rock material using a metal igniter, and more particularly, to accommodate a termit agent mixed with copper oxide and aluminum for rock fracture, in one or both sides of a cylindrical container containing an open, After filling, the receiving container is sealed with a receiving cap, and when electric energy is applied from the power supply device, a conductive magnesium metal for igniting the termite through instantaneous discharge is made into a strip or ribbon-shaped strip, and the inside of the receiving cap It is fixed to the installation, and fixedly installed on the outside of the receiving cap of a pair of wires to transfer the electrical energy, using a metal ignition body is a connector is installed on the cap to connect both ends of the magnesium strip and a pair of wires Thermite rock material.

In general, explosives and explosives used for rock crushing in civil works, construction work or underground tunnel excavation work are reacted chemically by a slight heat shock. It causes the object to be crushed.

However, such explosives and explosives are very unstable materials, so the rapid expansion reaction occurs easily by heat as well as minute impact and friction, so there are many safety risks in handling explosives such as explosives and explosives.

In particular, underground excavation work raises worker safety issues due to the toxic gas of the gunpowder. In addition, vibration generated during the blasting of the gun causes serious cracking in structures such as surrounding buildings, resulting in problems such as construction delay due to civil complaints.

Therefore, an explosive material that is highly stable in storage and that can be controlled to obtain a large explosive force or a required explosive power in case of an explosion has been developed. The plasma wave method using electrical energy instead of gunpowder is one of them.

The plasma wave method uses plasma generated by pulse power, and has higher energy efficiency than the wave method using gunpowder, while less scattering of rocks, less noise, and almost no harmful gas are generated. Excellent at

Such a power shock beam by the plasma wave method is disclosed by Korean Utility Model Publication No. 0173472. As shown in FIG. 1, the plasma shock power shock wave 10 includes a branch pipe 20 forming an inner space closed by an insulating wall 12, and an electrolytic filling in the inner space of the branch pipe 20. It consists of a material 30, an inner conductor 40 penetrating the central portion of the insulating wall 12 and an outer conductor 50 connected to the inner conductor 40.

Electric wires (not shown) are respectively connected to the outer conductor 50 and the inner conductor 40 to supply current, and a non-conductor 42 is included in the center of the inner conductor 40.

The conventional electric shock shock 10 as described above is driven as follows. The voltage applied from the external power source is rapidly heated by the supply of the electric current of the large current supplied to the inner conductor 40 through the wire to vaporize, causing thermite reaction to the electrolytic material 30, and the high temperature and high pressure energy required for the rock. Will be generated.

However, in the conventional electric shock shock 10 having such a structure, since the current passing through the inner conductor 40 must flow along the outer conductor 50 formed outside the electrolytic material 30, the outer conductor 50 A space equal to the diameter is required to have a structure in which the impact shock 10 and the perforation cannot be completely contacted. This means the loss of pressure generated, also known as loss by the decoupling effect, the gap between the perforation (not shown) and the impact shock (10) weakens the explosion impact force Cause.

In addition, the insulator 142 surrounds the outer circumferential surface of the inner electrode 140, and the outer electrode 150 is positioned in contact with the outer circumferential surface of the insulator 142.

As described above, since the internal and external electrodes 140 and 150 are formed coaxially inside the branch pipe 120, the decoupling effect is reduced compared to the conventional power bomb 쎌 10 for plasma rock, thereby increasing the rock force. However, there are the following problems.

Although the inner electrode 140 and the outer electrode 150 are formed inside the branch pipe 120, the branch pipe 120 is simply composed of an insulating wall 112 to accommodate the electrolytic material 130. Although the assembly is not easy and the inner and outer electrodes 140 and 150 are coaxial, an insulator 142 must be provided between the inner and outer electrodes 140 and 150, and the structure thereof is complicated. The internal electrode 140 and the external electrode 150 should be electrically connected. In the above-described structure, it is difficult to electrically connect the external electrode 140. The external electrode 150 has a plurality of insulator caps or a plurality of perforations for discharge. There is also a problem to be provided.

The tube tweeters 260 and 262 are hollow and fix the wires 250 and 252 to the tweeters 260 and 262 by inserting the wires 250 and 252 into the tubes and press-fitting them. The jacks 260 and 262 may be formed in the cap 230 as conductive aluminum or copper, or may be integrally formed with the cap 230.

At least two holes must be drilled in the planar portion 232 of the receiving cap 230 in order to install or pass through the connectors 260 and 262. In another embodiment of the present invention, the cap is used to drill the hole. The 230 may further include seating parts 270 and 272 on which the connectors 260 and 262 are seated. That is, as illustrated in FIG. 5, the mounting portions 270 and 272 in which the tweets 260 and 262 are seated therein are formed in the planar portion 232 of the cap to protrude outwards. When the 262 is inserted into the seating parts 270 and 272 and pressed, the jacks 260 and 262 are fixed to the cap 230.

Since the first wire 250 and the second wire 252 are electrically connected to the power supply device, rocking is performed by turning on the power supply device.

As such, when the electrical energy required for the reaction is stored and released at a time by the power supply device, the instantaneous discharge occurs when the electrical energy flows between the two wires in an instant. At the same time as the discharge, a large amount of high heat is generated as the aluminum is oxidized, and impact force is generated on the rock through thermite reaction.

As described above, the present invention does not cause any obstacle in charging the thermite into the perforated hole because the magnesium metal in the strip shape is completely embedded in the receiving container, and the non-conductor may be provided around the magnesium metal for insulation. In order to provide a termite rock material using a metal igniter that does not need, the termite rock material using a metal igniter has a termit agent exerting a rocking force, an accommodating container accommodating the same, a accommodating cap detachable from the accommodating container, and the cap. Consists of a magnesium strip is installed on the inside of the, it can be seen that the technical idea that the configuration in which the connector for connecting the both ends of the magnesium strip and the pair of wires is installed in the cap. Within the scope of the basic technical idea of the present invention, many other modifications will be possible to those skilled in the art.

As described above, according to the configuration of the present invention, the following effects can be expected.

First, by producing a thermite rock material using a metal ignition body as a receiving container and a receiving cap is expected to be easy to effect the assembly.

Second, since the metallic strip, which is a conductor, is assembled to the housing in a state where it is installed in the housing cap, the effect of the strip being provided inside the housing is expected.

Third, since the metallic strip is integrally formed in the shape of a ribbon, an economic effect is expected to be provided separately or without an insulator therebetween.

Fourth, since the metallic strip is installed in the receiving cap together with the wire through the connector, the effect is expected that the structure is solid and the safety of the work is guaranteed.
