Ground surface subsidence treatment device
The invention discloses an earth surface subsidence treatment device which comprises a high-pressure pump and a grouting pipe fitting, one end of the grouting pipe fitting is communicated with the output end of the high-pressure pump, the other end of the grouting pipe fitting extends into a grouting hole for grouting, and the earth surface subsidence treatment device is characterized by further comprising a buffering mechanism which comprises a buffering cavity and a pressure relief cavity. The buffer cavity is communicated with the pressure relief cavity, a piston assembly is movably connected in the buffer cavity, an intercepting assembly is movably connected in the pressure relief cavity, and the buffer cavity is filled with a hydraulic medium. The pressure of fluid in the grouting pipe acts on the piston assembly in the buffer cavity to buffer the pressure in the grouting pipe, and when the pressure acting on the piston assembly reaches a critical value, the piston assembly presses a hydraulic medium in the buffer cavity into the pressure relief cavity under the pressure effect to relieve pressure. The hydraulic medium entering the pressure relief cavity presses the intercepting assembly out to intercept the grouting pipe, and impact of backflow liquid on the water pump is avoided.
本发明公开了地表沉陷治理装置，包括高压泵和注浆管件，所述注浆管件一端与所述高压泵输出端连通，所述注浆管件另一端伸入注浆孔内进行注浆，其特征在于，还包括缓冲机构，所述缓冲机构包括缓冲腔和泄压腔，所述缓冲腔和所述泄压腔之间也连通，所述缓冲腔内活动连接有活塞组件，所述泄压腔内活动连接有拦截组件，所述缓冲腔内填充有液压介质，该地表沉陷治理装置，注浆管内的流体压力作用在缓冲腔内的活塞组件上对注浆管内的压力进行缓冲，当作用在活塞组件上的压力达到临界值时，活塞组件在压力作用下将缓冲腔内的液压介质压入到泄压腔内进行泄压，进入到泄压腔内的液压介质将拦截组件压出将注浆管拦截，避免了回流的液体对水泵造成冲击。
