[0002] Cofferdam technology is an important part of the construction system of water conservancy project structures. It is a temporary building of cofferdam. The application of this technology can prevent soil and water from entering the buildings on the construction site. It can be used for cofferdam drainage, foundation pit engineering, etc. It is an important part of water conservancy projects. The cofferdam needs to be removed after the project is completed. The height of the cofferdam during the construction phase is generally higher than the peak water level of the building. The key to the quality of farmland water conservancy projects lies in the cofferdam technology. Therefore, in the construction of farmland water conservancy projects, it is necessary to standardize the cofferdam construction site to ensure the safety and stability of the water conservancy project.

[0003] The current cofferdam technologies mainly include earth-rock cofferdams, concrete cofferdams and steel sheet pile cofferdams. Earth-rock cofferdams are mainly used for internal construction in wide rivers. Concrete cofferdams are more troublesome during construction and dismantling, and are suitable for deeper foundation pit construction. Steel sheet pile cofferdams are the most suitable for the construction of farmland water conservancy projects, but the steel sheet pile cofferdams currently on the market have complex structures, are not easy to install, and have problems with expandability and stability.
