[0035] As a technical optimization solution of the present invention, the provision of the U-shaped clamping block 47 can increase the strength of the U-shaped clamping block 47 and avoid the deformation of the U-shaped clamping block 47 during the load-bearing process.

[0036] The working principle and use process of the utility model are as follows: when in use, the pit foundation 1 sets up the support frame 2, and then the reinforcement columns 3 are inserted in sequence to assist in fixing the position of the support frame 2, and then the turntable 42 is rotated clockwise, the rotation of the turntable 42 drives the rotating rod 41 to rotate, the rotation of the rotating rod 41 drives the fixed sleeve 43 to rotate, the rotation of the fixed sleeve 43 drives the S-shaped slide groove 6 to rotate and change its position to force the sliding column 45 to move forward, the sliding column 45 moves forward and drives the fixed sleeve 43 to move along, the fixed sleeve 43 moves forward and drives the connecting column 46 and the U-shaped block 47 to move synchronously, the U-shaped block 47 moves and drives the synchronous rod 53 and the movable sleeve 52 to move along, the movable sleeve 52 moves on the surface of the fixed rod 51 and compresses the return spring 8 to do work, and finally the U-shaped blocks 47 approach each other to fix the reinforcement column 3, so that the reinforcement column 3 and the support frame 2 support the pit foundation 1 to achieve the effect of connection and fixation.
