Ground anchor and fender post combined buttress type foundation pit supporting structure and construction method
A counterfort type foundation pit supporting structure combining ground anchors and fender posts comprises the fender posts, top beams, ground anchor piles and the ground anchors, the fender posts are arranged in the direction of a foundation pit sideline in a driving mode, the fender posts are arranged at certain intervals in the direction perpendicular to the direction of the foundation pit sideline, and the fender posts in the direction of the foundation pit sideline and the fender posts in the direction perpendicular to the direction of the foundation pit sideline form a counterfort type structure. A plurality of top beams of T-shaped structures are poured on the tops of the fender posts, embedded sleeves are embedded in the top beams of the T-shaped structures in the direction perpendicular to the sideline of the foundation pit, ground anchors penetrate through the embedded sleeves in the top beams and are firmly connected with the top beams through anchorage devices, and the other ends of the ground anchors are connected to the ground anchor piles. The counterfort type foundation pit supporting structure combining the ground anchor and the fender post is adopted, the depth adaptability of the foundation pit is greatly enhanced, compared with cantilever supporting, the counterfort type foundation pit supporting structure can be used for a deeper foundation pit, deformation of the foundation pit can be better controlled, inner supporting does not exist, construction of an inner structure of the foundation pit is facilitated, the ground anchor is located on the ground surface, and the stress condition and the working state of the ground anchor are easy to check.
一种地锚、围护桩相结合的扶壁式基坑支护结构，包括围护桩、冠梁、地锚桩和地锚，沿基坑边线方向打设围护桩，垂直基坑边线方向每隔一定距离打设若干围护桩，沿基坑边线方向的围护桩和垂直基坑边线方向的围护桩形成扶壁式结构，围护桩的顶部浇筑若干T型结构的冠梁，在T型结构的垂直基坑边线方向的冠梁内部埋设预埋套管，地锚穿过冠梁内部的预埋套管，地锚通过锚具与冠梁进行牢固连接，地锚的另一端连接在地锚桩上。本发明采用地锚、围护桩相结合的扶壁式基坑支护结构，基坑深度适应性大大增强，与悬臂支护相比可用于更深的基坑，可以更好地控制基坑变形，不存在内支撑，有利于基坑内结构的施工，地锚位于地表，易于检查地锚的受力情况及工作状态。
