[0002] A cofferdam refers to a temporary retaining structure built for the construction of permanent water conservancy facilities in the construction of water conservancy and water transport projects. Its function is to prevent water and soil from entering the construction site of the building, so as to drain water, excavate foundation pits, and build buildings within the cofferdam. In recent years, with the nationwide promotion of the transformation and upgrading of small-scale water conservancy projects, more farmland water conservancy projects have been started every year, such as flood control and drought relief projects, agricultural irrigation projects, channel projects, aqueduct projects, etc. While carrying out these small-scale water conservancy projects, it is inevitable to encounter various engineering and technical problems.

[0023] A seepage-proof water-retaining cofferdam structure comprises a plurality of groups of weir plates 1 spliced ​​to each other, two groups of weir plates 1 close to each other are detachably fixed by connecting joints 2, the connecting joints 2 comprise two groups of rotating clamps 21 that are buckled to each other, one side of the two groups of rotating clamps 21 are penetrated by limiting columns 22, the other side of the rotating clamps 21 are detachably provided with weir plates 1, the outer sides of the two groups of rotating clamps 21 are detachably provided with sealing pads 3, the bottom of the weir plate 1 is provided with a support pad 4, both sides of the support pad 4 are provided with arc surfaces, the bottom end of the support pad 4 is flush with the bottom end of the weir plate 1, and one end of the sealing pad 3 extends to be flush with the bottom end of the weir plate 1.

[0024] It should be noted that: in this embodiment, two groups of weir plates 1 close to each other are spliced ​​together in sequence using connecting joints 2 to form an enclosed space, wherein the sealing gasket 3 can ensure the sealing between the weir plate 1 and the construction plane on the one hand, and can provide a counterweight on the other hand to improve the supporting strength of the weir plate 1.

[0025] In this embodiment, two sets of rotating clamps 21 can adjust the installation angle and can be fixed by limiting columns 22, and then the weir plate 1 can be detachably fixed on the rotating clamps 21, so as to adjust the installation angle of the weir plate 1, thereby adapting to different construction areas and saving construction space.

[0026] like Figure 3 and Figure 4 As shown;

[0027] In an optional embodiment, the rotating clamp 21 includes a U-shaped mounting plate 211, a mounting sleeve 212 is provided on one side of the U-shaped mounting plate 211, and a weir plate 1 is provided on the other side. A limiting groove 213 is provided in the middle array of the mounting sleeve 212, and two groups of mounting sleeves 212 close to each other are staggered. A limiting protrusion 221 cooperating with the limiting groove 213 is provided in the bottom array of the limiting column 22, and an operating handle 222 is provided on the top of the limiting column 22.

[0028] In this embodiment: adjust the installation angle of the two sets of U-shaped mounting plates 211 and ensure that the limiting grooves 213 in the mounting sleeve 212 are aligned up and down. After the angle adjustment is completed, align the limiting protrusions 221 on the limiting column 22 with the limiting grooves 213 one by one and insert them vertically.
