[0026] Both ends of the outer wall of one side of the support column 1 are provided with sliding grooves 18, and a sliding block 16 is slidably connected in the sliding groove 18, one end of the sliding block 16 is rotatably connected to the support rod 15, and a support spring 17 is welded to the outer wall of the top end of the sliding block 16;

[0027] The auxiliary component 6 includes a reinforcement block 19 welded to the outer walls of both ends of the support column 1 and screw grooves provided on the outer walls of three sides of the reinforcement block 19;

[0028] The reinforcing block 19 is located in the screw groove and is installed with a reinforcing rod 20 by screws, and the reinforcing rod 20 is installed on the outer walls of both ends of the two support columns 1. The support column 1 is combined into a "mouth" shape by the reinforcing block 19 and the reinforcing rod 20, and the inside of the support column 1 can be used for personnel to walk around, which is convenient for support and does not affect the movement of personnel.

[0029] Both ends of the outer walls on both sides of the support column 1 are welded with hinged protrusions 21, and a stabilizing rod 22 is rotatably connected to the hinged protrusion 21, and the other end of the stabilizing rod 22 is hinged with a nail plate 23. After the support column 1, the reinforcing rod 20 and the stabilizing rod 22 are assembled, the reinforcing rod 20 supports the left and right sides of the support column 1, and the stabilizing rod 22 cooperates with the nail plate 23 to support the front and rear directions of the support column 1, thereby simultaneously ensuring the stability of the support column 1 and facilitating the maintenance of the stability of the support plate 8.

[0030] Embodiment 2:

[0031] Reference Figure 1-3 The support structure 4 includes a connection seat 7 installed at one end of the hydraulic push rod 3, a support plate 8 rotatably connected to the center of one side of the connection seat 7, and an angle assembly 5 rotatably connected to both ends of the connection seat 7. After the hydraulic push rod 3 is started, the position of the support plate 8 is adjusted through the connection seat 7, and the slope protection operation is performed by contacting the support plate 8 with the outer wall of the foundation pit. The hydraulic push rod 3 cooperates with the sliding support rod 15 to maintain the stability of the support plate 8;

[0032] The outer walls at both ends of the connecting seat 7 are welded with hinged protrusions 14, and the other end of the support rod 15 is rotatably connected to the hinged protrusion 14, and the other end of the support spring 17 is welded to the inner wall of the top end of the sliding groove 18.

The extended length of the screw rod 11 and the threaded tube 10 makes the contact surface of the support plate 8 and the foundation pit relatively parallel. Finally, the hydraulic push rod 3 is started. The hydraulic push rod 3 drives the support plate 8 to approach the outer wall of the foundation pit through the connecting seat 7, thereby supporting the foundation pit. When the hydraulic push rod 3 is started, the support rod 15 is pulled by the connecting seat 7, and one end of the support rod 15 is slidably connected in the sliding groove 18, and the tension support spring 17 cooperates with the hydraulic push rod 3 to support the support plate 8, thereby maintaining the stability of the support of the support plate 8.
