Waterway and port projects: Through measures such as dredging rivers and constructing ship locks, they improve and create shipping conditions, reduce transportation costs, and promote regional economic exchanges.

[0003] During the construction of water conservancy projects, in order to facilitate construction, it is usually necessary to separate the construction area from other water areas by a cofferdam, and then pump out the water in the enclosed area of ​​the cofferdam.
