Description
본 발명은 가연성 액체 및 기체를 파이프에 주입하여 전기 발화에 의해 암석등을 파쇄하는 파쇄방법 및 이에 사용되는 팽창통에 관한 것이다.The present invention relates to a method for crushing rock and the like by injecting flammable liquid and gas into a pipe and the expansion vessel used therein.
현재 암석을 파쇄하는 방법은 발파지점에 화약장전공을 천공하고 이에 화약을 장전하여 발파하므로서 암석을 파쇄하고 있다.Currently, the method of crushing the rock is to crush the rock by drilling gunpowder major at the blasting point and loading and blasting gunpowder.
그러나 이러한 화약에 의한 방법은 화약의 진동계수와 소음이 너무 커서 주거지역 근처에서는 그 피해가 많아 그 사용이 부적합한 문제가 있다.However, the method using the gunpowder has a problem that the vibration coefficient and noise of the gunpowder are so large that its damage is high near the residential area and its use is inappropriate.
본 발명은 암석등을 파쇄함에 있어서, 전기한 문제점을 제거코저 파이프 내에 솜이나 스펀지등의 충전체를 내입하고, 이에 석유등의 가연성 액체를 골고루 충전하고,상하캡을 씌운 후 상부캡의 주입구를 통해 산소를 주입하고, 이를 발파지점에 매설한 후 전기의 발열에 의해 점화 폭발시키므로서 그 팽창력으로 암석이 파쇄되게 하여 그 파쇄력은 우수하면서도 진동계수와 소음이 미세하여 주거지역의 인근에서도 사용이 가능하게 한 가연성 액체 및 기체를 이용한 암석파쇄방법 및 그 팽창통을 제공함에 본 발명의 목적이 있다.The present invention eliminates the above-mentioned problems in crushing rocks, etc. Injecting a filling material such as cotton or sponge into the nose pipe, filling the flammable liquids such as oil evenly, and capping the upper and lower caps, and then filling the inlet of the upper cap. Oxygen is injected through it, and it is buried at the blasting point and then ignited and exploded by the heat of electricity, which causes the rock to be crushed by its expansion force. It is an object of the present invention to provide a rock crushing method using a combustible liquid and gas and an expansion tube thereof.

이하, 본 발명의 실시예를 첨부도면에 의하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail by the accompanying drawings.
도 1 은 본 발명에 의한 팽창통의 분리사시도이고, 도 2 는 상하부에 나사부(1)(1')가 형성된 파이프(2)내에 솜이나 스펀지등 충전체(3)를 내입한다.Fig. 1 is an exploded perspective view of the expansion cylinder according to the present invention, and Fig. 2 embeds a filling material such as a cotton ball or a sponge into a pipe 2 having a threaded portion 1, 1 'formed at the top and bottom thereof.
여기서 파이프(2)은 그 용량에 따라 적당한 길이의 관을 선택 사용하므로서폭발력을 가감 사용할 수 있으며 그 재질은 금속이나 PVC등 관체를 형성할 수 있는 어떤재질의 사용도 가능하다.Here, the pipe (2) can be used to increase or decrease the explosive force by selecting the appropriate length of the pipe according to its capacity, the material may be any material that can form a tube such as metal or PVC.
충전체(3)는 가연성 액체 및 기체에 의해 용해되지 않는 재질로 되어야 하며, 모세현상과 공기의 유통을 위해 다공질 섬유이어야 한다.The filler body 3 should be made of a material which is insoluble by flammable liquids and gases, and should be porous fibers for capillary action and air circulation.
이와 같이 파이프(2)내에 내입된 충전체(3)에 대하여 가연성 액체를 흡수 충전시킨다.In this way, the filler 3 embedded in the pipe 2 is absorbed and filled with the flammable liquid.
여기서 가연성 액체는 휘발유는 물론 경유나 석유등 가열에 의하여 점화가능한 액체면 모두 가능하다.The flammable liquid may be gasoline as well as a liquid that can be ignited by heating such as light oil or oil.
이와 같이 충전체(3)에 대하여 가연성 액체를 흡수시킨 후, 파이프(2) 상하의 나사부(1)(1')에 반대형 나사부(4)(4)가 형성된 캡(5)(6)를 씌운다.After absorbing the flammable liquid into the filler 3 in this way, the caps 5 and 6 with the opposite threaded portions 4 and 4 are formed on the threads 1 and 1 'above and below the pipe 2. .
여기서 상부캡(5)은 중앙부에 책크밸브가 내입된 주입관(7)을 장착하고, 그 좌우에 전극선(8)(8')을 장착하여 캡 내측에서 서로 니크롬선(9)으로 연결되게 한 것이다.Here, the upper cap 5 is equipped with an injection tube 7 in which a chuck valve is inserted in the center, and electrode wires 8 and 8 'are mounted on the left and right sides thereof so that the nichrome wire 9 is connected to each other inside the cap. will be.
상하캡(5)(6)과 고무패킹(10)(10')에 의해 밀봉된 파이프(2)에 대하여 그 주입관(7)을 통해 산소를 주입한다.Oxygen is injected through the injection pipe 7 to the pipe 2 sealed by the upper and lower caps 5 and 6 and the rubber packings 10 and 10 '.
이와 같이 그 내부에 가연성 액체와 산소가 내입된 파이프(2)을 발파코저 하는 지점에 매립한 후 그 전극선(8)(8')에 전원을 연결시키게 되면 니크롬선(9)이 발열되면서 내부의 가연성 액체가 착화되어 팽창 폭발되는 것이다.In this way, when the pipe (2) in which flammable liquid and oxygen are introduced is buried at the point of blasting, and the power is connected to the electrode lines (8) and (8 '), the nichrome wire (9) generates heat while Flammable liquids ignite and expand and explode.
니크롬(9)의 발열에 의한 착화이므로 기존의 순간 착화에 비해 불발율이 전혀 없이 착화가 우수하고, 고장의 우려가 없다.Since the ignition is caused by the heat generation of the nichrome 9, the ignition is excellent without any misfire rate compared with the existing instantaneous ignition, and there is no fear of failure.
여기서, 폭발물이 화약이 아니고, 액체상태이므로 그 팽창력 때문에 파괴력은 충분히 유지되면서도 소음이나 진동은 적어서 안전한 사용이 가능하다.Here, the explosive is not a gunpowder, and because it is a liquid state, because of its expansion force, the breakdown force is sufficiently maintained while the noise or vibration is small, so that safe use is possible.
실제로 60.5㎜ 직경과 3.25㎜의 두께를 갖는 42.5㎝ 길이의 파이프(2)에 스폰지로 된 충전체(3)를 내입하고, 석유를 충전한 후, 25∼30kg 압력으로 산소를 주입시키고, 전극선(8)(8')에 220V의 A/C전기를 가한 결과 순간적으로 약 400,000㎏의 폭발력이 발생하였다.In fact, a sponge filled filler 3 is inserted into a 42.5 cm long pipe 2 having a diameter of 60.5 mm and a thickness of 3.25 mm, filled with petroleum, and then oxygen is injected at a pressure of 25 to 30 kg, and an electrode wire ( 8) (8 ') resulted in an explosive force of about 400,000 kg instantaneously when 220V A / C electricity was applied.
이상과 같이 본 발명은 파이프내에 가연성 액체를 골고루 충전시켜 전열에 의해 팽창 폭발되게 하므로서 암석등의 안전한 파쇄가 가능하며, 특히 주거지역 근처에서 진통이나 소음의 최소화로 그 발파작업이 가능한 효과가 있다.As described above, the present invention enables the safe crushing of rocks and the like by filling the combustible liquid evenly in the pipe to expand and explode by heat transfer, and in particular, the blasting work is possible by minimizing pain and noise in a residential area.
