Description

A water conservancy construction cofferdam device

technical field

The utility model relates to the technical field of water conservancy construction, in particular to a cofferdam device for water conservancy construction.

Background technique

Cofferdam refers to the temporary enclosure structure built for the construction of permanent water conservancy facilities in the construction of water conservancy projects. Its function is to prevent water and soil from entering the construction site of the building, so as to drain water in the cofferdam, excavate the foundation pit, and build the building. Generally, it is mainly used in hydraulic construction. Except as a part of formal buildings, cofferdams are generally removed after use.

Water conservancy construction cofferdam devices are usually spliced and installed through steel sheet piles, but in some places where the flow rate is relatively high, because the steel sheet piles are relatively thin, in order to ensure the overall strength and stability of the device, it is necessary to add multiple auxiliary steel sheets for reinforcement.
