Description

Technical Field

[0001] This utility model relates to the field of cofferdam technology, and in particular to a cofferdam device for water conservancy engineering construction. Background Technology

[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the goals of mitigating harm and promoting benefits. Water conservancy projects encompass multiple fields such as flood control, irrigation, power generation, water supply, and navigation, playing a crucial role in ensuring human production and life and promoting economic and social development. In the construction of water conservancy projects, cofferdams are important temporary water-retaining structures. They surround the construction area of ​​the water conservancy project, separating the construction area from the water body and creating a relatively dry and stable construction environment. Cofferdams have a wide range of uses and are indispensable in river regulation, dam construction, and lock construction. From an engineering perspective, cofferdams are essential for water conservancy projects. The basic guarantee provided by the cofferdam ensures smooth construction, shortens the construction period, and reduces costs. From a social perspective, the cofferdam creates conditions for the stable operation of water conservancy facilities, thereby ensuring flood control safety, providing clean energy, improving irrigation conditions, and promoting sustainable regional economic development. It also plays an indirect but far-reaching role in maintaining ecological balance and protecting people's lives and property. However, existing cofferdams cannot adjust the connection angle according to actual use, which is inconvenient for users. At the same time, most cofferdams are L-shaped, which is inconvenient for users to store after use. In view of this, this utility model is proposed. Utility Model Content
