One end of the screw 21 is rotatably connected to the arc plate 22, and the other end is fixedly connected to the handle 23. The arc plate 22 is used to contact the side wall of the pier. When working, the handle 23 is rotated, and the screw 21 is used to drive the arc plate 22 to move, so that the arc plate 22 is pressed against the pier, and then the support steel frame 1 and the pier are relatively fixed by the reaction force.

[0033] It should be noted that the locking assemblies 2 are arranged in pairs, each pair of locking assemblies 2 corresponds to a group of piers, and each pair of locking assemblies 2 is arranged opposite to each other along the radial direction of the piers, that is, there are two groups of locking assemblies 2 in this embodiment.

[0034] A hinge rod 41 is provided at the bottom of the side mold 4, and a hinge shaft is provided on the support steel frame 1, and the hinge rod 41 is hinged to the hinge shaft.
