The invention discloses a recoverable variable-angle combined type inclined supporting structure, and relates to the technical field of building foundation pit supporting, in particular to a recoverable variable-angle combined type inclined supporting structure which comprises an under-pit supporting part, an on-pit supporting part, a foundation pit fender post and a foundation slab, the under-pit supporting part comprises a lower prefabricated pipe pile, a grouting steel pipe and an expanded-base grouting bag, and the under-pit supporting part comprises a lower prefabricated pipe pile, a grouting steel pipe and an expanded-base grouting bag; a grouting steel pipe is fixed to the bottom of the lower prefabricated pipe pile, grouting holes are evenly formed in the side wall of the grouting steel pipe, the outer ring of the grouting steel pipe is wrapped with an expanded-base grouting bag, the top end of the expanded-base grouting bag is fixedly connected with the bottom end of the lower prefabricated pipe pile, and the outer surface of the expanded-base grouting bag is tightly attached to the cement pile body. According to the recoverable variable-angle combined inclined supporting structure, the mode that the steel pipes and the prefabricated pipe piles are combined and spliced is adopted, and the prefabricated pipe piles above the pit bottom can be completely recycled during supporting disassembly; the steel pipe is adopted at the position penetrating through the bottom plate, the diameter is relatively small, and the water stop construction quality is good.
本发明公开了一种可回收可变角度组合式斜向支撑结构，涉及建筑基坑支护技术领域，具体包括坑下支撑部、坑上支撑部、基坑围护桩和基础底板，所述坑下支撑部包括下预制管桩、注浆钢管和扩底注浆囊，所述下预制管桩的底部固定有注浆钢管，所述注浆钢管的侧壁上均匀设有注浆孔，所述注浆钢管的外圈包裹有扩底注浆囊，所述扩底注浆囊的顶端与下预制管桩的底端固定连接，所述扩底注浆囊的外表面与水泥桩体紧密贴合。该可回收可变角度组合式斜向支撑结构，采用钢管、预制管桩组合拼装的方式，拆撑时坑底以上的预制管桩可实现全部回收利用；穿过底板处采用钢管，直径相对较小，止水施工质量好。
