Soft and hard rock complex stratum foundation pit supporting structure and construction method thereof
The invention discloses a soft and hard rock complex stratum foundation pit supporting structure and a construction method thereof, and relates to the technical field of foundation building construction, the soft and hard rock complex stratum foundation pit supporting structure comprises a supporting cylinder, the outer diameter of the supporting cylinder is matched with the inner diameter of a foundation pit, and the supporting cylinder is coaxially arranged on a cylindrical pile in a sleeving mode; the supporting barrel comprises an inner reinforcement cage and an outer reinforcement cage which are sequentially and coaxially arranged from inside to outside, the inner reinforcement cage and the outer reinforcement cage are connected through straight ribs, a gap is reserved between the outer reinforcement cage and the inner side wall of the foundation pit, and the lower end of the inner reinforcement cage extends out of the outer reinforcement cage. The first anchor rod is used for penetrating through the side wall of the supporting cylinder, penetrating through the soft rock surface on the local inner side wall of the foundation pit and being anchored in a hard rock area; and the first anchor rod is horizontally or obliquely arranged upwards. By the adoption of the scheme, overall supporting can be conducted on the cylindrical pile through inside and outside sequential pouring of the supporting barrels, local supporting can be conducted on the cylindrical pile on the soft rock face, and therefore stability is improved.
本发明公开了一种软硬岩复杂地层基坑支护结构及其施工方法，涉及地基建筑施工技术领域，包括：支护筒，所述支护筒的外径和基坑内径尺寸相适配，且所述支护筒同轴套设于柱形桩上；所述支护筒包括从内到外依次同轴设置的内钢筋笼和外钢筋笼，所述内钢筋笼和外钢筋笼之间通过直筋连接，所述外钢筋笼和所述基坑内侧壁之间留有间隙，且所述内钢筋笼的下端伸出所述外钢筋笼；还包括第一锚杆，所述第一锚杆用于穿过所述支护筒侧壁，并穿过所述基坑局部内侧壁上的软岩面，并锚定于硬岩区域；所述第一锚杆水平或倾斜朝上设置。采用本方案，不仅能通过支护筒的内外依次浇筑形成对柱形桩进行整体支护，还能在软岩面处对柱形桩局部进行支护，以提高稳定性。
