After the multiple groups of anti-seepage mechanisms are connected together, the sealing of the gaps at the connection is poor. At high pressures, the anti-seepage mechanisms are subjected to greater pressure, and water will leak from the gaps at the connection. Therefore, an anti-seepage water-stopping structure for use in water conservancy and hydropower projects is proposed. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0026] The following describes an embodiment of the utility model based on its overall structure.

[0027] An anti-seepage and water-stopping structure used in water conservancy and hydropower projects, such as Figures 1 to 5 As shown, it includes a waterproof mechanism 1, and a fixing mechanism 2 is fixedly connected to the side wall of the waterproof mechanism 1;

[0028] The waterproof mechanism 1 includes a waterproof board body 101, one side of the waterproof board body 101 is fixedly connected with a protrusion 102, the other side of the waterproof board body 101 is provided with a groove 103 that matches the protrusion 102, a rubber plate 104 is slidably connected at the connection between the two groups of waterproof board bodies 101, the side wall of the rubber plate 104 is fixedly connected with an abutment plate 105, the outer wall of the waterproof board body 101 is provided with a waterproof coating 106, and the side wall of the waterproof board is fixedly connected with a plurality of side support beams 107, the waterproof The top of the board body 101 is fixedly connected with a wave-breaking board 108, the bottom end of the wave-breaking board 108 is arc-shaped, and the waterproof board body 101 includes concrete 1011, the outer wall of the concrete 1011 is sprayed with a waterproof coating 106, the interior of the concrete 1011 is wrapped with a steel layer 1012, and the interior of the concrete 1011 is provided with a cavity 1013, and a plurality of groups of reinforcing beams 1014 are arranged inside the cavity 1013, and the reinforcing beams 1014 are fixedly connected to the inner wall of the concrete 1011.

[0029] The foot of the dam is dug open, and a groove 103 that matches the side support beam 107 is opened on the side wall of the dam, and then the anti-seepage structure is placed on the dam, so that the bottom end of the waterproof board and the side support beam 107 are buried in the soil, and at the connection between the two sets of waterproof boards, the side of the abutment plate 105 away from the rubber board 104 is buried in the dam, and the rubber board 104 and the connection between the two sets of waterproof boards are fitted together. When the water outside the dam contacts the waterproof board, the water pressure on the waterproof board pushes the waterproof board to fit the rubber dam, so that the connection between the two sets of waterproof boards is more closely fitted on the rubber board 104, and As the water level rises, the pressure on the waterproof board increases, so that the waterproof board and the rubber board 104 fit closely together. The arc design at the bottom of the wave-breaking plate 108 allows the water to flow along the waterproof board to the bottom of the wave-breaking plate 108 after the waves hit the waterproof board, and then fall back into the river along the arc surface at the bottom of the wave-breaking plate 108, thereby preventing the waves from hitting the dam and causing soil loss on the dam. A cavity 1013 is provided inside the waterproof board body 101, so that the weight of the entire waterproof board body 101 is reduced, reducing the land subsidence caused by the heavy weight and avoiding damage to the dam.

[0030] Please refer to Figure 2 and Figure 3 The fixing mechanism 2 includes a plurality of connecting rods 201, each of which is fixedly connected between two adjacent groups of side support beams 107, and the plurality of connecting rods 201 are distributed in two layers, the side walls of each connecting rod 201 are connected with two groups of anchor rods 202, the outer walls of the anchor rods 202 are provided with slurry discharge holes 203 penetrating into the interior of the anchor rods 202, the top end of the upper connecting rod 201 is connected with a feeding pipe 204, the top end of the feeding pipe 204 is connected with a feeding port 205, the bottom end of the upper connecting rod 201 is connected with a connecting pipe 206, and the bottom end of the connecting pipe 206 is connected to the top of the lower connecting rod 201.

[0031] Fixing holes are opened in advance on the side of the dam. When the anti-seepage mechanism is installed on the dam, the anchor rod 202 is inserted into the fixing hole, and then concrete 1011 is injected into the feeding pipe 204 through the feeding port 205. The concrete 1011 flows into the connecting rod 201 through the feeding pipe 204, and then flows into the anchor rod 202, and also flows into the lower connecting rod 201 through the connecting pipe 206, so that multiple groups of anchor rods 202 are filled with concrete 1011, and then the concrete 1011 is discharged into the fixing hole through the slurry discharge hole 203 on the anchor rod 202, so that the connection between the anchor rod 202 and the dam is sufficiently strong, thereby improving the strength between the dam and the anti-seepage structure.

[0032] When in use, a rubber plate 104 is arranged at the connection between the two groups of water-proof structures, and an abutment plate 105 is fixed on the side wall of the rubber plate 104. During use, the side wall of the abutment plate 105 is connected to the dam, and the pressure exerted by water on the waterproof plate body 101 makes the waterproof plate body 101 fit tightly on the rubber plate 104. The higher the water level, the greater the pressure on the waterproof plate, so that the waterproof plate and the rubber plate 104 fit more tightly, avoiding the problem of water seepage at the connection of the waterproof plate. The parts not involved in the device are the same as the prior art or can be implemented by the prior art.
