Deep foundation pit supporting construction method for large-pipe-diameter prestressed row piles
The invention discloses a deep foundation pit supporting construction method for large-pipe-diameter prestressed row piles. According to the construction method, the large-pipe-diameter prestressed row piles are used for supporting, profile steel and pre-buried grouting pipes are arranged in the pipe piles to improve the overall bearing capacity of the prestressed pipe piles, so that the supporting depth can reach 10-23m, the fabricated prestressed pipe piles are adopted as supporting piles to replace cast-in-place diaphragm walls, row piles and other structures, and waste of on-site resources and the influence on the surrounding environment are reduced. The fabricated structural steel is arranged in the large-pipe-diameter pipe pile for supporting, the supporting capacity of the large-pipe-diameter pipe pile is improved, and when the fabricated structure is applied to underground engineering, the large premise that the fabricated structure is popularized in China at present is met, and meanwhile the national requirement for energy-saving, environment-friendly and green buildings is met.
本发明公开了一种大管径预应力排桩的深基坑支护施工方法，采用大管径预应力排桩进行支护，且在管桩内设置型钢和预埋注浆管的施工方法提高预应力管桩的整体承载力，使支护深度可以达到10m～23m。采用装配式预应力管桩作支护桩代替现浇地连墙、排桩等结构，减少了现场资源浪费及对周边环境的影响。且在大管径管桩内设置装配式型钢进行支撑，增加了大管径管桩的支撑能力，将装配式结构运用于地下工程中不仅符合目前国家推广装配式结构的大前提，同时也符合国家要求节能环保绿色建筑的要求。
