[0002] A cofferdam is a temporary retaining structure built for the construction of permanent water conservancy facilities. It can effectively prevent water and soil from entering the construction site of the building so that drainage can be carried out within the cofferdam, foundation pits can be excavated, and buildings can be built. Generally, after the construction is completed, the cofferdam will be dismantled.
[0003] However, there are still some problems in the cofferdam structure currently in use, such as the lack of supporting and reinforcing structure in the cofferdam, which makes it easy for the cofferdam to bend and deform when affected by the water flow. Summary of the invention

The arranged threaded rod is connected in the threaded sleeve, which further enhances the stability of the entire cofferdam structure.
[0012] As a preferred technical solution of the present invention: anti-skid pads are respectively installed on the plate surfaces of the top plate and the limit plate. The anti-skid pads on the top plate and the limit plate can make the supporting and fixing effect of the supporting mechanism more stable.
