[0009] By adopting the above structural design, the side formwork and the main formwork can be disassembled in sequence, reducing the difficulty of disassembly; reducing the resistance between the side formwork and the inner support plate, reducing the difficulty of disassembly.

[0010] Preferably, the reserved hole includes a mounting portion matching the blocking plate and a blocking portion matching the disassembly screw, and the mounting portion is communicated with the blocking portion.

[0011] By adopting the above structural design, the disassembly screw can be passed through the reserved hole from the tail end.

[0012] Preferably, a rotating ring is arranged on the outer side of the rotating cylinder, and a support rod is fixedly connected between the rotating cylinder and the rotating ring.

[0015] By adopting the above structural design, the side formwork and the main formwork can be pulled out from the caisson together, thereby increasing the disassembly speed.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1) When dismantling the jacking hole formwork, the concrete at the corners of the caisson jacking hole will not be damaged.

[0018] 2) This device can disassemble the side formwork and the main formwork in sequence, reducing the difficulty of disassembly.
