The invention provides a foundation pit steel supporting structure capable of controllably applying prestress. The foundation pit steel supporting structure comprises a plate body, a steel frame and extrusion plates; the plate body is of a hollow structure, the multiple extrusion plates are evenly arranged on the side wall of the plate body, and the steel frame is connected to the inner side wall of the plate body in a sliding mode; the foundation pit steel supporting structure further comprises a pressing mechanism, an adjusting mechanism and a locking mechanism; the pressing mechanism is fixedly connected to the outer surface of the steel frame and used for providing extrusion pre-tightening force for the foundation pit; the adjusting mechanism is arranged on the inner surface of the plate body and used for adjusting the pre-tightening force of the pressing mechanism; and the locking mechanism is fixedly connected to the inner surface of the plate body through the adjusting mechanism and used for locking the adjusting mechanism. Certain pre-tightening force is applied to the inner wall of the foundation pit through the pressing mechanism, so that an identification mechanism can detect the inner wall of the foundation pit in real time so as to prompt constructors that collapse and depression occur in the foundation pit, and the constructors can maintain the foundation pit conveniently.
本申请提供了可控式施加预应力的基坑钢支撑结构，包括板体、钢架和挤压板，所述板体为中空结构设置，所述板体的侧壁均匀设置有多个所述挤压板，所述板体的内侧侧壁滑动连接有钢架，还包括：压紧机构，所述压紧机构固定连接于钢架的外表面，用于对基坑提供挤压预紧力；调节机构，所述调节机构设置于板体的内表面上，用于调节所述压紧机构预紧力的大小；锁紧机构，所述锁紧机构通过调节机构固定连接于所述板体的内表面，用于对调节机构进行锁止作用。通过压紧机构对基坑内壁施加一定的预紧力，使得标识机构可以对基坑内壁进行实时检测，以便提示施工人员基坑内发生了塌落凹陷，便于施工人员对基坑进行维护处理。
