Foundation pit supporting system and construction method thereof

WU ZHENZHI / CHEN MAOJUN / WU ZHENZHEN

The invention discloses a foundation pit supporting system and a construction method thereof. The foundation pit supporting system comprises a plane supporting system arranged on the slope surface ofa foundation pit and an anchoring supporting system acting inside the slope body of the foundation pit, wherein the plane supporting system is fixedly connected to the anchoring supporting system; theplane supporting system and/or the anchoring supporting system are/is further provided with a pre-tensioning system, and the pre-tensioning system comprises: a pre-tightening part for pre-tighteningand applying force to the plane supporting system and/or the anchoring supporting system; a tensioning device for tensioning and pre-tightening the pre-tightening piece; and an adjusting assembly formonitoring a stress condition of the plane supporting system and/or the anchoring supporting system and adjusting the tensioning pre-tightening degree of the pre-tightening piece at the correspondingposition. The foundation pit supporting system has the effects of adjusting the stress strength of the whole supporting system, can adapt to different external loads in time, achieves the reliable supporting effect, and is simple in structure, low in cost and suitable for application and popularization.

本发明公开了基坑支护体系及其施工方法，该基坑支护体系包括设置于基坑坡面上的平面支撑体系、以及作用于基坑坡体内部的锚固支撑体系，所述平面支撑体系与所述锚固支撑体系固定连接，所述平面支撑体系和/或所述锚固支撑体系上还设置有预紧张拉体系，所述预紧张拉体系包括：预紧件，对所述平面支撑体系和/或所述锚固支撑体系进行预紧施力；张拉装置，对所述预紧件进行张拉预紧；调节组件，监测所述平面支撑体系和/或所述锚固支撑体系受力情况并调节对应位置预紧件的张拉预紧程度。本发明具有能够调节整体支护体系受力强度的效果，能够及时适应不同外部荷载，达到可靠的支撑效果，且结构简单，成本较低，适合推广应用。
