[0002] At present, in the process of water conservancy construction, some construction sites need to be constructed on the ground of the river, that is, underwater construction is required. In order to facilitate construction, the water in the construction area needs to be drained to facilitate manual operation. At present, the common method is to use a cofferdam to surround the construction area, isolate the water flow inside the construction area from the outside, and after the water flow in the cofferdam is drained, manual construction is carried out inside the cofferdam.

[0003] However, the existing cofferdam devices still have the following shortcomings: 1. The cofferdam devices on the market have too many complex structures and are not easy to install. Therefore, we propose a water conservancy construction cofferdam device; 2. The cofferdam devices on the market do not have the function of ensuring the safety of the workers. When the workers are working in the cofferdam, if a water leakage accident occurs, the consequences will be disastrous. Utility Model Content
