[0006] A clamping mechanism is provided on one side of the support plate, and the clamping mechanism includes a clamping plate, an I-shaped frame, a through hole, a screw and a pressure plate. A clamping plate is fixedly installed on one side of the support plate, and an I-shaped frame is fixedly installed on one side of the inner wall of the clamping plate. A through hole is opened on one side of the clamping plate, and a screw that penetrates and extends into the I-shaped frame is threadedly connected to the inner wall of the through hole, and a pressure plate connected to the clamping plate is fixedly installed on one end of the screw.

[0007] In one example, a connecting plate is fixedly installed at the bottom of the I-shaped frame, and a cross plate is hinged at the bottom of the connecting plate.

[0008] In one example, a groove is formed on one side of the support plate, and a mounting block is slidably connected to the inner wall of the groove.

[0009] In one example, a mounting groove is provided on one side of the mounting block, an inner wall of the mounting groove is rotatably connected to a fixed shaft, and the fixed shaft is rotatably connected to the transverse plate.

[0010] In one example, a steel structure crossbeam is fixedly installed on one side of the I-shaped frame.

[0011] In one example, reinforcing ribs are fixedly installed on both sides of the steel structure crossbeam, and the other ends of the two reinforcing ribs are fixedly connected to the I-shaped frame.

[0012] The foundation pit steel sheet pile support structure proposed by the utility model can bring the following beneficial effects:

[0013] 1. A foundation pit steel sheet pile support structure is provided by engaging an I-shaped frame with a clamping plate, and then passing a screw through a through hole and threadedly connecting the I-shaped frame to the I-shaped frame to achieve a fixing effect. At the same time, a steel structure crossbeam is installed on one side of the I-shaped frame to fix it, and reinforcing ribs are installed on both sides of the steel structure crossbeam to provide auxiliary reinforcement, thereby being able to provide better and more stable support for the I-shaped frame, and better support and stabilize the steel sheet pile body, thereby facilitating better operation in the foundation pit.
