Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy and hydropower engineering, in particular to a water seepage prevention device for water conservancy and hydropower engineering construction. Background Art

[0002] Water seepage prevention during construction is a critical task that aims to prevent water from entering or penetrating buildings or structures, thereby ensuring their stability, lifespan and safety. Water seepage prevention is particularly important during the construction of water conservancy and hydropower projects.

[0003] For example, the Chinese utility model provides "a water-seepage prevention device for the construction of water conservancy and hydropower projects", announcement number: CN216275477U, which includes a wall panel, a waterproof board is provided on the side of the wall panel, and mounting blocks are provided on all four sides of the inner wall of the waterproof board. There are two groups of mounting blocks, and the two groups of mounting blocks are vertically arranged. An axle rod is provided at the middle position of the opposite side of the two groups of mounting blocks, and the outer wall of the axle rod is sleeved with a sliding block. The utility model can resist the impact of water flow through the waterproof board and the support rod. The external water flow hits the top of the waterproof board, and then drives the waterproof board to move toward the wall panel, and then drives the support rod to rotate, so that the support rod squeezes the mounting frame, so that the mounting frame can buffer the force of the water flow hitting the top of the waterproof board, and at the same time reduce the long-term erosion effect of the wall panel, thereby making the wall panel more anti-water seepage effect.

[0004] Although the water-seepage prevention device for water conservancy and hydropower engineering construction in the above-mentioned technology can reduce the impact of water flow on the wall panels, due to the lack of an effective sealing structure on the side of the wall panels during the overall use, the joints between the two sets of wall panels are prone to water seepage due to the long-term erosion of water flow during the overall splicing process, thereby adversely affecting the overall stable use.

[0005] The purpose of the utility model is to provide a water-seepage prevention device for the construction of water conservancy and hydropower projects, which has the advantage of effectively improving the sealing and water-seepage prevention effect of the overall splicing and ensuring that the overall structure can be used stably for a long time.

[0009] As a preferred solution, the protective plate is movably connected to guide slide bars on all four sides, and the left side of the guide slide bar is fixedly connected to the lower end of the right side of the water retaining wall plate.

[0010] As a preferred solution, a pressure relief valve is fixedly installed on the upper end of the left side of the rubber airbag through a pipeline.

The provision of the rubber sealing ring effectively improves the sealing performance of the contact between the piston and the air guide box. BRIEF DESCRIPTION OF THE DRAWINGS
