Pile-wall combined supporting structure for supporting deep foundation pit and construction method of pile-wall combined supporting structure
The invention discloses a construction method of a pile-wall combined supporting structure for supporting a deep foundation pit, which mainly comprises the steps of rotary excavating secant pile construction, reinforcing pile construction, joint pouring and the like, and is characterized in that secant pile construction is adopted for the deep foundation pit, and reinforcing piles are additionally arranged around the secant pile construction for connection, so that the supporting use of different deep foundation pits is met; through secant pile construction, reinforcing piles are additionally arranged on the outer side, and meanwhile, through reinforced concrete fixation, the deep foundation pit construction risk caused by collapse and pile body inclination due to soil pressure is reduced; the secant piles and the reinforcing piles are connected through the reinforced concrete, so that the stable supporting performance is improved, the pile body inclination risk is avoided, and the overall stability is improved.
本发明公开了一种支护深基坑的桩墙联合支护结构的施工方法，主要步骤包括旋挖咬合桩施工、加固桩施工、浇筑连接处等，本发明深基坑采用咬合桩施工，在其周围增加加固桩连接，进而满足不同深基坑支护使用；通过咬合桩施工，在外测增加加固桩，同时通过钢筋混凝土固定，减少坍塌，桩体因土压力倾斜，造成的深基坑施工风险；利用钢筋混凝土连接咬合桩与加固桩，使其增加稳定支撑性，避免桩体倾斜风险，进而提高了整体的稳定性。
