Foundation pit supporting structure of arch-shaped supporting system outside pit and construction method thereof
The invention discloses a foundation pit supporting structure of an arch-shaped supporting system outside a pit and a construction method thereof. The structure comprises arch-shaped supporting structures outside the pit, supporting piles, top beams, diagonal braces, angle braces, connecting rods and stand columns, wherein, the top beams are arranged at the tops of the supporting piles; the arch-shaped supporting structures consist of arch ribs and slings, two ends of the arch ribs intersect with the top beams, one ends of the slings are anchored on the arch ribs, and the other ends of the slings are anchored on the top beams; the arch-shaped supporting structures are arranged outside the pit on the side wall of a long-edge foundation pit, the diagonal braces are arranged in the pit at arch foot, the angle braces are arranged on the side wall of a short-side foundation pit, and the stand columns are arranged in the middles of the diagonal braces and the angle braces; and therefore, the foundation pit supporting structure of the arch-shaped supporting system outside the pit is formed. According to the foundation pit supporting structure and the construction method thereof, the characteristic that the arch-shaped structures are reasonable in stress is fully utilized, the foundation pit supporting structure has the advantages of being large in rigidity, large in span, high in deformation control capacity, convenient to construct, recyclable in part of components and the like, supports in the pit can be greatly reduced, the safety of the foundation pit is improved, the construction period is shortened, and the construction cost is saved.
本发明公开了一种坑外拱形支撑体系的基坑支护结构及其施工方法，该结构包括坑外拱形支撑结构、支护桩、冠梁、对撑、角撑、连杆、立柱；支护桩顶部设有冠梁；拱形支撑结构由拱肋和吊索组成，拱肋两端交于冠梁，吊索一端锚固在拱肋上，另一端锚固在冠梁上；拱形支撑结构设置在长边基坑侧壁的坑外，拱脚处的坑内设置对撑，短边基坑侧壁设置角撑，对撑和角撑的中部设置立柱；以此形成一种坑外拱形支撑体系的基坑支护结构。本发明的基坑支护结构及其施工方法，充分利用了拱形结构受力合理的特征，具有刚度大、跨度大、控制变形能力强、施工方便、部分构件可回收等优点，可大幅减少坑内支撑、提高基坑安全、缩短施工工期、节省工程造价。
