Pile-wall integrated pile structure unit and slope excavation-free foundation pit supporting structure
The invention discloses a pile-wall integrated pile structure unit, which is used for supporting a foundation pit in underground space structure construction, and comprises a fender post and a soil retaining pile which are integrally poured, the horizontal section of the fender post is circular; the horizontal section of the soil retaining pile is semicircular, the circle center of the soil retaining pile and the circle center of the fender post are located on the same vertical straight line, and the bottom end of the soil retaining pile and the top end of the fender post are integrally poured together. Bolt sleeves which are horizontally arranged are pre-buried in the soil retaining piles, and the bolt sleeves are used for being connected with the soil retaining plates through bolts; the multiple bolt sleeves are evenly arranged up and down at intervals. The invention further discloses a slope excavation-free foundation pit supporting structure using the pile-wall integrated pile structure unit. The construction of a pile top retaining wall and a top beam through slope excavation is avoided, the construction occupied space is greatly saved, the constraint of surrounding ground road traffic, surrounding existing buildings and municipal pipelines during construction is minimized, and the construction cost is greatly reduced.
本发明公开了一种桩墙一体化桩结构单元，在地下空间结构施工中用于支护基坑，包括一体浇筑而成的围护桩和挡土桩；围护桩的水平截面为圆形；挡土桩的水平截面为半圆形，挡土桩的圆心与围护桩的圆心位于同一竖向直线上，挡土桩的底端与围护桩的顶端一体浇筑在一起；挡土桩内预埋有水平设置的螺栓套筒，螺栓套筒用于通过螺栓连接挡土板；螺栓套筒上下均匀间隔设有若干个。本发明还公开了使用上述桩墙一体化桩结构单元的免放坡开挖基坑支护结构。避免放坡开挖施做桩顶挡土墙及冠梁，极大节省了施工占地空间，施工时受到周边的地面道路交通、周边既有建筑物以及市政管线的约束得到最小化，施工成本大幅降低。
