Tensile reinforced foundation pit supporting structure

The utility model provides a tensile reinforced foundation pit supporting structure, which is characterized in that the bottom end of a rectangular plate is fixedly connected with a supporting plate, the top end of the rectangular plate is fixedly connected with a top block, the bottom of the right surface of the top block is fixedly connected with a fixing plate, a first tension bracing mechanism is arranged at the center of the top surface of the fixing plate, and two sides of the top surface of the fixing plate are respectively provided with a second tension bracing mechanism; the two second tension bracing mechanisms are symmetrically arranged relative to the first tension bracing mechanism, the included angle between each second tension bracing mechanism and the first tension bracing mechanism is an acute angle, and the left side of the first tension bracing mechanism and the left side of each second tension bracing mechanism are both fixedly connected to the top block. The tensile strength of the tensil
