Steel sheet pile foundation pit supporting structure and construction method thereof
The invention discloses a steel sheet pile foundation pit supporting structure which comprises steel sheet piles, a steel sheet pile enclosure is defined by the steel sheet piles, corner pile structures are arranged at the corners of the steel sheet pile enclosure and comprise steel pipe piles and a plurality of pipe pile locking openings fixed to the steel pipe piles, and the steel sheet piles are provided with sheet pile locking openings. The pipe pile locking openings are connected with the sheet pile locking openings, and the included angle formed between the pipe pile locking openings is consistent with the corner formed by the adjacent steel sheet piles. The invention further discloses a construction method of the steel sheet pile foundation pit supporting structure. The defects that a steel sheet pile enclosure is difficult to lap at the corner, the soil retaining and water stopping effects are poor, and an enclosure weak point exists at the corner can be overcome, the safety of the foundation pit enclosure is improved, and construction is convenient.
本发明公开了一种钢板桩基坑支护结构，该钢板桩基坑支护结构包括钢板桩，钢板桩围设形成钢板桩围护，钢板桩围护的转角处设有转角桩结构，转角桩结构包括钢管桩和固定于钢管桩的多个管桩锁口，钢板桩上设有板桩锁口，管桩锁口与板桩锁口连接，管桩锁口之间形成的夹角与相邻的钢板桩形成的转角一致。本发明还公开了该钢板桩基坑支护结构的施工方法。本发明可解决钢板桩围护在转角处搭接困难，挡土、止水效果不好，转角处存在围护薄弱点的缺陷，增加基坑围护安全性且施工便利。
