[0026] The area surrounded by the first arc-shaped plate 31 and the second arc-shaped plate 35 is equal to the area of the inflated air bag 32, so that water can be prevented from leaking into the cofferdam through the joint.
[0027] The sealing rubber strip 22 and the clamping block 23 are matched, so that water can be prevented from flowing into the cofferdam through the gap of the clamping block 23.
[0028] In the embodiment, the first cofferdam 1 is hoisted to a designated position by a crane, and then the second cofferdam 11 is hoisted by the crane, so that the clamping block 23 enters the U-shaped clamp 21, thereby enabling the first cofferdam 1 and the second cofferdam 11 to be spliced, which is convenient for construction and easy to disassemble, thereby improving the turnover rate.
