Abstract
본 발명은 에어 해머 드릴장치의 작동에 이용된 배기 에어를 이용하여 굴삭토사를 효율적으로 배토(俳土)하는 에어 해머 굴삭공법 및 장치에 관한 것이다.The present invention relates to an air hammer excavation method and apparatus for efficiently discharging excavated soil by using exhaust air used in the operation of the air hammer drill device.
본 발명의 에어 해머 굴삭장치의 밀봉용 굴관(30')의 외주부에는 원통형상으로 형성된 회전 파이프(67)가 설치되어 있는 한편, 기부(16)에는 밀폐장치(65')가 설치되어 있고, 이 밀폐장치(65')는 원통형상으로 형성된 덮개부재(68')의 내주면에 탄성체로 형성된 실(seal)부재(70')가 설치되어 있고, 실부재(70')의 내주부는 상기 회전파이프(67)의 외주부를 밀봉하고 있으며, 상기 회전파이프(67)는 이 실부재(70')의 내주면상을 미끄러져 움직인다.On the outer circumferential portion of the sealing oyster pipe 30 'of the air hammer excavator device of the present invention, a rotary pipe 67 formed in a cylindrical shape is provided, while a base 65 is provided with a sealing device 65'. The sealing device 65 'is provided with a seal member 70' formed of an elastic body on an inner circumferential surface of the cover member 68 'formed in a cylindrical shape, and an inner circumference of the seal member 70' is formed with the rotary pipe. The outer circumferential portion of 67 is sealed, and the rotary pipe 67 slides on the inner circumferential surface of the seal member 70 '.
이것에 의해 굴삭공(48)내가 밀폐된다. 따라서, 굴삭공(48)내는 배토에 필요한 가압상태를 유지할 수 있으므로 충분한 배기 에어의 유속을 얻을 수 있어 굴삭토사의 배토를 효율적으로 할 수 있다.As a result, the inside of the excavation hole 48 is sealed. Therefore, the inside of the excavation hole 48 can maintain the pressurized state required for the excavation, so that a sufficient velocity of exhaust air can be obtained, and the excavation of the excavated soil can be efficiently carried out.
