Abstract
본 발명은 하수도 공사등에 필요한 입갱구축장치에 관한 것이다.The present invention relates to a shaft construction device required for sewage construction and the like.
본 발명에 입갱구축장치는, 지중에 입설한 관상체 내부에 장착되고, 방사 방향으로 확대수축 가능한 확관수단과, 상기 확관수단을 상기 관상체의 축선방향으로 이동시키는 이동수단으로 구성된다. 그리고 상기 확관수단은, 상기 관상체 내면을 따라 거의 원형으로 배열됨과 동시에 상기 관상체의 방사 방향으로 확대 수축가능한 누름부재를 구비하는 상부확관기구 및 하부확관기구로 구성되고, 더욱이 상기 이동수단이 상기 상부확관기구와 하부확관기구의 간격을 축선 방향으로 변환하는 신축기구로 구성된다. 상기 관상체는 상호 접동 가능한 외관 및 내관으로 되며, 상기 내관의 하단부에 저반을 부착하고, 상기 저반에는 역방지밸브를 구비하는 주수공 및 그라우트주입공이 설치되어 있다.The shaft contracting device according to the present invention comprises expansion means which is mounted inside a tubular body placed in the ground, which can be expanded and contracted in a radial direction, and moving means which moves the expansion means in the axial direction of the tubular body. And the expansion means comprises an upper expansion mechanism and a lower expansion mechanism arranged in a substantially circular shape along the inner surface of the tubular body and having a pressing member capable of expanding and contracting in the radial direction of the tubular body. It consists of a telescopic mechanism that converts the gap between the upper and lower expansion mechanisms in the axial direction. The tubular body has a mutually slidable exterior and an inner tube, and a bottom plate is attached to the lower end of the inner tube, and the bottom plate is provided with a main hole and a grout injection hole having a check valve.
