Foundation pit gas lift reverse circulation dewatering device and method
The invention discloses a foundation pit gas lift reverse circulation dewatering device and method. A water outlet communicating the interior and exterior of a hollow pipe is formed in the top of a hollow cylindrical steel pipe, and used for being connected with a water outlet pipe; a plurality of through holes communicating with the outside are uniformly formed in the bottom wall of the hollow pipe; a trash holding grid is arranged outside the bottom of the hollow pipe and communicates with the through holes; an air inlet pipe is arranged on the lower part of one side of the hollow pipe in acommunicating mode, an air outlet of the air inlet pipe is located in the hollow pipe and faces the bottom wall of the hollow pipe, and an air inlet of the air inlet pipe is located outside the hollowpipe and communicates with an air compressor; and a water stop gasket is arranged between the air outlet of the air inlet pipe and the bottom wall of the hollow pipe, and the water stop gasket is separably laid on the bottom wall of the hollow pipe and covers all the through holes. The foundation pit gas lift reverse circulation dewatering device is energy-saving and environment-friendly, and foundation pit dewatering is effectively achieved.
本发明公开了一种基坑气举反循环降水装置及方法，空心圆柱钢管的顶部设有连通空心管内部和外部的出水口，出水口用于连接出水管；空心管的底壁均匀分布有多个与外部相通的通孔；空心管的底部外设有拦污格栅，拦污格栅与通孔相通；空心管的一侧下部连通有进气管，进气管的出气口位于空心管内部并朝向空心管的底壁，进气管的进气口位于空心管外部并连通有空压机；进气管的出气口和空心管的底壁之间设有止水垫片，止水垫片可分离地铺设在空心管的底壁上并覆盖所有通孔。本发明节能、环保，有效实现基坑降水。
