Description

Technical Field

[0001] The utility model relates to the technical field of water utilization dam anti-seepage, in particular to water utilization dam anti-seepage equipment. Background Art

[0002] Levee is a general term for dikes and dams, and also refers to buildings and structures that are used to prevent water from flowing. For example, we need to speed up the construction of levees to prevent floods. There are two main types of modern dams: earth-rock dams and concrete dams. In recent years, large levees have been built with high-tech reinforced concrete.

[0003] Existing dams can regulate and control water flows, control river water levels and avoid floods. When river water levels exceed safe levels, reservoirs can temporarily store water and relieve flood pressure through flood discharge and other means to protect the safety of surrounding areas.

[0004] However, the existing dams are in contact with the impact of water flow all year round. Over time, the impact of water flow can easily cause damage to the dams. Once the dams are damaged, on the one hand, maintenance costs need to be invested, and on the other hand, the damaged dams pose great hidden dangers when floods come. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a water-utilizing dam anti-seepage device, which solves the problem that the dam is in contact with the impact water flow all year round. As a result, the impact water flow can easily damage the dam over time. Once the dam is damaged, it will not only require maintenance costs, but also pose a great hidden danger when a flood comes.

[0006] To achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a water-utilizing dam anti-seepage equipment, including a dam body, an anti-impact device is arranged on the water-facing side of the dam body, the anti-impact device includes a buffer plate, a drainage groove, and a circular hole, the buffer plate is installed on the outermost side of the dam body, a plurality of circular holes are opened on the surface of the buffer plate, a drainage groove is opened on the inner wall of the buffer plate, and the buffer plate is connected to the circular hole.

[0007] Preferably, a composite geomembrane layer is laid on one side of the buffer plate close to the dam body, a waterproof cloth layer is laid on the other side of the composite geomembrane layer, a resin glue layer is laid on the other side of the waterproof cloth layer, a concrete layer is laid on the other side of the resin glue layer, and the concrete layer is laid on the side of the dam body.

[0008] Preferably, a fixing piece is installed on the surface of the buffer plate, and the fixing piece passes through the buffer plate, the composite geomembrane layer, the waterproof cloth layer, the resin glue layer and the concrete layer in sequence from the outside to the inside, and is embedded in the interior of the dam body.

[0009] Preferably, a base is provided at the bottom of the dam body, and a plurality of fixing blocks are provided at the bottom of the base.

[0010] Preferably, a riverbed is laid on the bottom of the base, and the fixing block is inserted into the interior of the riverbed.

[0011] Beneficial Effects

[0012] The utility model provides a water utilization dam anti-seepage device. It has the following beneficial effects: the water utilization dam anti-seepage device cooperates between a buffer plate, a circular hole and a drainage groove. When the water-facing side of the dam body is impacted by river water, it will first be blocked by the buffer plate, and the impact force of the river water can be reduced through multiple circular holes on the surface of the buffer plate. The river water that enters the buffer plate through the circular holes is discharged from the drainage groove, thereby reducing the impact force of the dam body on the river water.

[0013] Through the cooperation between the composite geomembrane layer, the waterproof cloth layer and the resin adhesive layer, the river water impacting the dam body will be blocked in turn by the buffer plate, the composite geomembrane layer, the waterproof cloth layer, the resin adhesive layer and the concrete layer. The composite geomembrane layer has high physical and mechanical properties such as tensile strength, tear resistance and bursting resistance. The product has the characteristics of high strength, good elongation, large deformation modulus, acid and alkali resistance, corrosion resistance, aging resistance, good anti-seepage performance, etc. It can maximize the penetration of small river water, and then it is blocked by the waterproof cloth layer, resin adhesive layer and concrete layer to prevent the river water from penetrating into the inside of the dam body.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The existing dams are in contact with the impact of water flow all year round. Over time, the impact of water flow can easily cause damage to the dams. Once the dams are damaged, on the one hand, maintenance costs need to be invested, and on the other hand, the damaged dams pose a great hidden danger when floods come.

[0021] In view of this, the utility model provides a water-utilizing dam anti-seepage device. Through the cooperation among the buffer plate, the circular holes and the drainage grooves, when the water-facing side of the dam body is impacted by the river water, it will first be blocked by the buffer plate, and the impact force of the river water can be reduced by the multiple circular holes on the surface of the buffer plate. The river water that enters the buffer plate through the circular holes is discharged by the drainage grooves, thereby reducing the impact force of the river water on the dam body.

[0022] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.

The anti-impact device includes a buffer plate 6, a drainage groove 7, and a circular hole 8. The buffer plate 6 is installed on the outermost side of the dam body 1. The buffer plate 6 can reduce the impact force of the river water. The surface of the buffer plate 6 is provided with a plurality of circular holes 8. The plurality of circular holes 8 can spread the impact force received by the buffer plate 6. The inner wall of the buffer plate 6 is provided with a drainage groove 7. The buffer plate 6 is connected with the circular hole 8.

[0024] In the specific implementation process, it is worth pointing out that, through the cooperation between the buffer plate 6, the circular hole 8 and the drainage groove 7, when the water-facing side of the dam body 1 is impacted by the river water, it will first be blocked by the buffer plate 6, and the impact force of the river water can be reduced by the multiple circular holes 8 on the surface of the buffer plate 6. The river water that enters the buffer plate 6 through the circular holes 8 is discharged by the drainage groove 7, thereby reducing the impact force of the river water on the dam body 1;

[0025] Further, a composite geomembrane layer 5 is laid on one side of the buffer plate 6 close to the dam body 1. The composite geomembrane layer 5 has high physical and mechanical performance indicators such as tensile strength, tear resistance, and bursting resistance. The product has the characteristics of high strength, good elongation, large deformation modulus, acid and alkali resistance, corrosion resistance, aging resistance, and good anti-seepage performance. A waterproof cloth layer 4 is laid on the other side of the composite geomembrane layer 5. The waterproof cloth layer 4 can block most of the river water that penetrates into it. A resin glue layer 3 is laid on the other side of the waterproof cloth layer 4. The resin glue layer 3 is a polymer compound with viscosity and adhesion. A concrete layer 2 is laid on the other side of the resin glue layer 3. The concrete layer 2 is laid on the side of the dam body 1;

[0026] In the specific implementation process, it is worth pointing out that the river water impacting the dam body 1 will be blocked in turn by the buffer plate 6, the composite geomembrane layer 5, the waterproof cloth layer 4, the resin glue layer 3 and the concrete layer 2. The composite geomembrane layer 5 has high physical and mechanical performance indicators such as tensile strength, tear resistance, and bursting resistance. The product has the characteristics of high strength, good elongation, large deformation modulus, acid and alkali resistance, corrosion resistance, aging resistance, and good anti-seepage performance, which can maximize the penetration of small river water, and then blocked by the waterproof cloth layer 4, the resin glue layer 3 and the concrete layer 2, so that the river water will not penetrate into the dam body 1;

[0027] Furthermore, a fixing member 12 is installed on the surface of the buffer plate 6, and the fixing member 12 passes through the buffer plate 6, the composite geomembrane layer 5, the waterproof cloth layer 4, the resin glue layer 3 and the concrete layer 2 from the outside to the inside, and is embedded in the interior of the dam body 1;

[0028] In the specific implementation process, it is worth pointing out that the buffer plate 6, the composite geomembrane layer 5, the waterproof cloth layer 4, the resin adhesive layer 3 and the concrete layer 2 are all fixed to the water-facing side of the dam body 1 by the fixing member 12 to prevent them from falling off due to the impact of the river water for a long time;

[0029] Specifically, when using the water-utilizing dam anti-seepage equipment, when the water-facing side of the dam body 1 is impacted by river water, it will first be blocked by the buffer plate 6. The multiple circular holes 8 on the surface of the buffer plate 6 can reduce the impact force of the river water.

[0032] Furthermore, the bottom of the base 11 is paved with a riverbed 9, and the fixing block 10 is inserted into the interior of the riverbed 9;
