Foundation pit supporting structure capable of controlling continuous damage of foundation pit and construction method of foundation pit supporting structure
The invention relates to a foundation pit supporting structure capable of controlling continuous damage of a foundation pit and a construction method of the foundation pit supporting structure. The foundation pit supporting structure comprises a plurality of foundation pit supporting piles arranged along the edge of a foundation pit; the at least one arch-shaped body is arranged along the edge of the foundation pit, the arch-shaped body is arranged between the foundation pit supporting piles, and the arch-shaped body is in an arch shape with an arch opening facing the foundation pit on the horizontal plane; the reinforcing piles are arranged along the edge of the foundation pit, and the reinforcing piles are connected to the two ends, in the horizontal direction, of the arch-shaped body; and the top beam is arranged along the edge of the foundation pit and used for connecting the foundation pit supporting piles, the arch-shaped bodies and the reinforcing piles on the edge of the foundation pit. The arch-shaped body is arranged in the middle of the foundation pit supporting structure to serve as a blocking unit, the arch-shaped body can convert soil pressure on the arch face into internal force of the arch-shaped body, the soil pressure is concentrated at the end of the arch-shaped body, the safety of the whole arch-shaped body structure can be guaranteed only by strengthening the end, and the supporting cost is saved.
本发明涉及一种能控制基坑连续破坏的基坑支护结构及其施工方法。本发明中基坑支护结构包括：基坑支护桩，所述基坑支护桩沿基坑边缘布置有若干；拱形体，所述拱形体沿基坑边缘布置有至少一个，拱形体设置于所述基坑支护桩之间，该拱形体在水平面上呈拱口朝向基坑的拱形；加强桩，所述加强桩沿基坑边缘布置，该加强桩接于所述拱形体水平方向的两端；冠梁，所述冠梁沿基坑边缘布置，用于连接基坑边缘的基坑支护桩、拱形体和加强桩。本发明在基坑支护结构中间设置拱形体作为阻断单元，拱形体可以将拱面上的土压力转化为拱形体的内力，将土压力集中在拱形体端部，只需要进行端部强化即可保证整个拱形体结构安全，节约支护成本。
