Soft soil foundation porous deep compressed air drainage device and construction method
The invention relates to a soft soil foundation porous deep compressed air drainage device and a construction method, the soft soil foundation porous deep compressed air drainage device comprises a compressed air pipe and a drainage pipe, a drainage cavity and a gas diffusion cavity are buried in a soft soil foundation, and the drainage cavity is located around the gas diffusion cavity; the gas diffusion cavity is connected with a gas pressing pipe, and the gas pressing pipe extends out of the earth surface in the vertical direction of the soft soil foundation and communicates with an inflation pump. The drainage cavity is connected with a drainage pipe, one end of the drainage pipe extends into the bottom of the drainage cavity, and the other end of the drainage pipe extends out of the earth surface in the vertical direction of the soft soil foundation. The air pressure pipe is used for inflating the air diffusion cavity, the air pressure of the air diffusion cavity is kept larger than the pore water pressure of the surrounding soil body and smaller than the self-weight pressure of the soil body, the air extrudes the surrounding soil body to drive underground water in the soil body to flow to the drainage cavity and then flow out of the earth surface through the drainage pipe, and deep drainage of the soft soil foundation is achieved. And the deep soft soil drainage consolidation time is shortened.
本发明涉及一种软土地基多孔深部压气排水装置及施工方法，包括压气管和排水管，在软土地基内分别埋设有排水空腔体和气体扩散空腔体，且排水空腔体位于气体扩散空腔体的周围；气体扩散空腔体连接有压气管，且压气管沿软土地基的竖向伸出至地表外并与充气泵相连通；排水空腔体连接有排水管，且排水管的一端伸入至排水空腔体的底部，另一端沿软土地基的竖向并伸出至地表外；利用压气管向气体扩散空腔体充气，保持气体扩散空腔体的气压大于周围土体的孔隙水压力并小于土体的自重压力，利用气体向四周土体挤压驱动土体中的地下水流向排水空腔体，然后经排水管流出地表，实现软土地基深部排水，缩短深部软土排水固结时间。
