Construction method of deep foundation pit supporting structure with underground water
The invention discloses a construction method of a deep foundation pit supporting structure with underground water, the structure comprises an underground diaphragm wall arranged on the inner side of a foundation pit, a concrete bottom sealing plate arranged at the bottom of the foundation pit and a bin dividing wall, the underground diaphragm wall and the bin dividing wall are both provided with anti-shear grooves, and the end of the concrete bottom sealing plate is connected with the anti-shear grooves; a plurality of transverse supporting beams are arranged on the underground diaphragm wall; a rectangular preset piece is preset in the anti-shear groove and comprises a waterproof layer and compressed soil bricks arranged in the waterproof layer, and when the waterproof layer is damaged, the compressed soil bricks expand and diffuse towards the outer side of the waterproof layer when meeting water; the method comprises the steps of underground diaphragm wall construction, transverse supporting beam construction, underwater construction, underwater concrete bottom sealing, building structure construction and backfill construction. The structure has good stability and safety, underwater operation of personnel is reduced, the construction cost is reduced, the safety of the construction process is enhanced, the construction period is shortened, and manpower and material resources are saved.
本发明公开了一种具有地下水的深基坑支护结构的施工方法，该结构包括设置在基坑内侧的地下连续墙、设置在基坑底部的混凝土封底板和分仓墙，在地下连续墙和分仓墙均设置有抗剪槽，混凝土封底板的端部与抗剪槽相连；在地下连续墙上设置多道横向支撑梁；在抗剪槽内预设有矩形预设件，矩形预设件包括防水层及设置在防水层内部的压缩土砖，当防水层被破坏、压缩土砖遇水向防水层外侧膨胀扩散；该方法包括施工地下连续墙、施工横向支撑梁、水下施工、水下混凝土封底、建筑结构施工和回填施工。该结构具有较好的稳定性及安全性，减少了人员进行水下作业，降低了施工成本，增强了施工过程的安全性，该方法缩短了施工周期，节省人力物力。
