[0002] During the construction of water conservancy projects, cofferdams, as temporary retaining structures, play a vital role. They are primarily used to prevent water and soil from entering the building's construction site, allowing for drainage, excavation, and building construction within the cofferdam. The presence of cofferdams allows construction to proceed in a dry and stable environment, significantly improving efficiency and project quality.

Anchor grooves 2 are arranged in the anchor grooves 2. The cofferdam plates 1 are fixedly connected to the ground through the anchors 3. Threaded grooves 4 are opened on the top and bottom of the inner side of the cofferdam plates 1. The cofferdam plates 1 are fixedly connected to support plates 5 through the threaded grooves 4.

[0028] Example 1: The cofferdam plate 1 is bent, the vertical plate of the cofferdam plate 1 is inclined inward, and the horizontal plate of the cofferdam plate 1 is in a horizontal state. By setting the main body of the cofferdam plate 1 to be inclined inward, the cofferdam plates 1 can form an arch structure after being combined. When the outer side of the cofferdam plate is subjected to water pressure, the water pressure under the action of the inclined surface can act on the fitting surface between the cofferdam plates, making the cofferdam plates fit more tightly and improving the overall sealing effect of the cofferdam plate installation.

[0029] Example 2: The anchor groove 2 passes through the side and bottom of the cofferdam plate 1, and a circular groove 6 is opened on the outside of the anchor groove 2. The shape of the end of the anchor 3 is adapted to the shape of the circular groove 6, and a sponge pad 7 is fixedly connected to the inside of the circular groove 6. By arranging the anchor groove 2 with the anchor 3 on the cofferdam plate 1, the cofferdam plate 1 is fixedly connected to the bottom of the water, and the disc at the end of the anchor 3 will withstand a part of the water pressure after installation, so that the anchor 3 is more closely connected to the bottom soil layer, so that the anchor can convert the water pressure it needs to withstand into a force that improves the stability of the cofferdam plate 1. The sponge pad 7 can improve the sealing between the circular groove 6 and the anchor 3, and enable the anchor 3 to move inward deeper into the soil layer when subjected to water pressure.

[0030] Example 3: The support plate 5 is in a vertical state, and a number of screws 8 are threadedly connected between the support plate 5 and the cofferdam plate 1. The position specifications of the screws 8 are compatible with the position specifications of the thread groove 4. By arranging the support plate 5 on the inner side of the cofferdam plate 1, it is combined with the cofferdam plate 1 to form a triangular structure, so that it has a stable physical structure, further improving the stability of the cofferdam plate 1, and when the cofferdam plate 1 leaks, the support plate 5 can play a certain interception role to prevent the leaked water from directly entering the inside of the cofferdam plate, reserving time for construction personnel to remedy the leaking cofferdam plate 1, and the support plate 5 can cover the reinforcement structures such as the anchor nails 3 inside the cofferdam plate 1, so that the inner wall of the cofferdam remains smooth, avoiding the exposed reinforcement structure from affecting the construction equipment.
