Triangular lattice supporting row pile foundation pit supporting structure and construction method thereof
The invention discloses a triangular lattice supporting row pile foundation pit supporting structure and a construction method thereof, and the supporting structure comprises a row pile system which comprises a pile body and a top beam, and the top beam is connected to the top of the pile body; the inclined supporting system comprises inclined columns, waist beams, foot beams and a net hanging and concrete spraying surface layer, when the inclined columns excavate earth and stone in a layered mode from top to bottom, all excavation layers are sequentially and obliquely arranged side by side in a V shape to form triangular lattices, the tops of the inclined columns are connected with the pile bodies, and the waist beams are located at the bottoms of all the excavation layers and connected with the bottoms of the inclined columns. The foot beams are located in the last excavation layer and connected with the bottom ends of the inclined columns to be arranged in the socketed rocks, and the triangular lattices are filled with the hanging net concrete spraying surface layers. Under the condition that anchor rods are not used for fixing and an inner supporting structure is not used, the deep foundation pit slope can be supported, operation cannot be carried out beyond the construction range red line, the situation that the space in the foundation pit is excessively occupied to affect construction in the foundation pit is avoided, meanwhile, the stability of the foundation pit slope is guaranteed, foundation pit collapse is prevented, and construction is easy and convenient.
本发明公开了一种三角形框格支撑排桩基坑支护结构及其施工方法，支护结构包括：排桩体系，包括桩体和冠梁，冠梁连接在桩体的顶部；斜支撑体系，包括斜柱、腰梁、脚梁和挂网喷砼面层，斜柱在由上至下分层开挖土石方时每一开挖层呈V形依次并排倾斜排列组成三角形框格，斜柱的顶部与桩体连接，腰梁位于每一开挖层底部并连接斜柱的底部，脚梁位于最后一开挖层内且与斜柱底端连接置于嵌岩内，挂网喷砼面层填补在三角形框格内。在不使用锚杆固定与不使用内支撑结构的情况下，本发明能对较深基坑边坡进行支护，既不会超出施工范围红线外进行操作，也不会过多占用基坑内空间影响基坑内施工，同时保障基坑边坡稳定性，防止基坑坍塌，施工简易方便。
