[0002] Ecological cofferdams refer to temporary enclosure structures built in water conservancy project construction to build permanent water conservancy facilities, or to protect the ecological environment around rivers, lakes and other water bodies. Their function is to prevent water and soil from entering the construction site of the building, so as to drain water, dig foundation pits, build buildings, or have functions such as flood control, anti-scouring, and water quality improvement. Among them, ecological cofferdams used in hydraulic structures are generally dismantled after use, except as part of formal buildings.

[0032] In this embodiment, several cofferdam plates 1 set in the environmentally friendly ecological cofferdam are connected by bolts to form a temporary enclosure structure. The plug-in strips 2 and the U-shaped connecting strips 3 are fixedly connected on both sides of the cofferdam plates 1. After the plug-in strips 2 and the U-shaped connecting strips 3 between adjacent cofferdam plates 1 are plugged in, the plug-in strips 2 and the U-shaped connecting strips 3 can be fixed from the first connecting hole 5 and the second connecting hole 6 by bolts, so that the connection position between the adjacent cofferdam plates 1 can be limited. After the plug-in strips 2 and the U-shaped connecting strips 3 are connected, the first sealing pad 4 can be located between the contact surfaces of the plug-in strips 2 and the U-shaped connecting strips 3, thereby enhancing the connection between the adjacent cofferdam plates 1. The sealing of the connection can enhance the effect of intercepting water flow when the environmentally friendly ecological cofferdam is in use. Furthermore, a hydraulic cylinder 7 is symmetrically fixedly connected to the top of the inner wall of the cofferdam plate 1. Starting the hydraulic cylinder 7 can control the limit pile 8 to move up and down. By controlling the downward movement of the limit pile 8, it can be nailed into the inside of the land, thereby limiting the layout of the cofferdam plate 1. When the cofferdam plate 1 is laid, the waterproof sealing between the bottom of the cofferdam plate 1 and the ground can be enhanced by the second sealing pad 9.
