High underground water level post-cast strip structure and post-cast strip sealing construction method
The invention relates to a high underground water level post-cast strip structure and a post-cast strip sealing construction method.The high underground water level post-cast strip structure comprises foundation soil, a cushion layer, a post-cast strip cushion layer and a post-cast strip concrete layer from bottom to top and further comprises a drainage device, the drainage device comprises a double-wall corrugated pipe, a drainage pipe and a water pumping pipe, and the double-wall corrugated pipe extends to the foundation soil from the post-cast strip concrete layer; one end of the drainage pipe is located in the double-wall corrugated pipe and is spaced from the inner wall of the double-wall corrugated pipe, and the other end of the drainage pipe extends out of the double-wall corrugated pipe and is connected with a flange valve; the outer surface of the double-wall corrugated pipe is covered with water seepage holes and wrapped with a layer of steel wire mesh. In the post-cast strip concrete pouring process, the drainage device is installed at the water burst point, water is pumped through the water pump, the water pressure of confined water is reduced, a soil layer at the bottom of the post-cast strip is prevented from protruding, and it is guaranteed that post-cast strip concrete pouring is conducted smoothly.
本发明涉及一种高地下水位后浇带结构及后浇带封闭施工方法，自下而上包括地基土、垫层、后浇带垫层和后浇带混凝土层，还包括排水装置，排水装置包括双壁波纹管、排水管和抽水管，双壁波纹管自后浇带混凝土层延伸至地基土，排水管一端位于双壁波纹管内且与双壁波纹管内壁间隔设置，另一端伸出双壁波纹管且连接有法兰阀，抽水管一端可插入排水管内，另一端连接水泵；双壁波纹管外表面布满渗水孔和包裹有一层钢丝网。在后浇带混凝土浇筑过程中，本发明在涌水点安装排水装置，通过水泵抽水，降低了承压水的水压力，避免后浇带底部的土层隆起，确保后浇带混凝土浇筑顺利进行。
