Construction method of strong permeable layer foundation pit supporting anti-seepage composite structure
The invention discloses a construction method of a strong permeable layer foundation pit supporting anti-seepage composite structure, which comprises the following steps: firstly, constructing a double-wheel milling cement soil anti-seepage wall, and inserting I-shaped steel into the double-wheel milling cement soil anti-seepage wall to form a composite vertical supporting structure; then, a first ring beam is poured and constructed on the top of the double-wheel milling cemented soil diaphragm wall, a first layer of horizontal supports are arranged on the first ring beam, then a foundation pit is excavated, in the excavation process of the foundation pit, a next ring beam is constructed on the inner wall of the double-wheel milling cemented soil diaphragm wall every certain depth, and horizontal supports are arranged on each ring beam; vertical connecting beams are constructed between the upper and lower adjacent ring beams; after excavation is conducted to the bottom of the foundation pit, a foundation pit floor is poured, a vertical supporting beam is constructed between the foundation pit floor and the last ring beam, and then basement construction is conducted; and dismantling each layer of horizontal support step by step from bottom to top according to the underground structure construction progress. By means of the method, the foundation pit of the strong permeable layer foundation can be effectively supported, and the safety of the foundation pit excavation and underground structure construction process is guaranteed.
本发明公开了一种强透水层地基基坑支护防渗复合结构的施工方法，首先构建双轮铣水泥土防渗墙，并在其中插入工字钢形成复合竖向支护结构；然后在双轮铣水泥土防渗墙顶部浇筑构建首道圈梁，在首道圈梁上布置第一层水平支撑，然后开挖基坑，在基坑开挖过程中，每隔一定的深度在双轮铣水泥土防渗墙内壁上构建下一道圈梁，并且在每道圈梁上布置水平支撑；并且在上下相邻的各道圈梁之间构建竖向连接梁；开挖至基坑底后，浇筑基坑地板，并在基坑地板和最后一道圈梁之间构建竖向支撑梁，然后进行地下室施工；根据地下结构施工进度自下而上逐级拆除各层水平支撑。本方法能够有效对强透水层地基基坑进行支护，保证开挖基坑和地下结构施工过程的安全性。
