Anchor cable and fender post combined support-free foundation pit supporting structure and construction method
The invention discloses an anchor cable and fender post combined support-free foundation pit supporting structure and a construction method thereof, the anchor cable and fender post combined support-free foundation pit supporting structure comprises fender posts, top beams, connecting beams and pre-stressed anchor cables, the top beams are constructed on the tops of the fender posts, the protruding connecting beams are connected to the sides, facing the periphery of a foundation pit, of the top beams at intervals of one pile, pre-stressed anchor cable construction holes are reserved in the connecting beams, and the pre-stressed anchor cables are arranged in the pre-stressed anchor cable construction holes. The pre-stressed anchor cables are connected to the pre-stressed anchor cable construction holes of the connecting beams through anchorage devices, and the pre-stressed anchor cables and the fender posts are buried underground at a certain angle. Under the condition that construction land is insufficient, the influence on adjacent buildings and peripheral pipelines and land occupation outside a red line can be reduced to the maximum extent, no inner support exists, construction of an inner structure of the foundation pit is facilitated, the depth adaptability of the foundation pit is enhanced, compared with cantilever supporting, the method can be used for a deeper foundation pit, and deformation of the foundation pit is well controlled.
锚索、围护桩相结合的无支撑基坑支护结构及其施工方法，包括围护桩、冠梁、联系梁和预应力锚索，围护桩的顶部施工冠梁，冠梁朝向基坑外围的一侧间隔一桩连接有凸出的联系梁，联系梁上预留有预应力锚索施工孔，预应力锚索通过锚具连接在联系梁的预应力锚索施工孔处，并将预应力锚索与围护桩成一定角度埋设地下。本发明在施工用地紧张的情况下可最大限度减少对紧邻建筑物、周边管线的影响及红线外土地侵占，不存在内支撑，有利于基坑内结构的施工，基坑深度适应性增强，与悬臂支护相比可用于更深的基坑，较好地控制基坑变形。
