Abstract
Description
Technical Field
[0001] This utility model relates to the field of dam slope protection technology, and in particular to dam slope protection structures based on water conservancy and hydropower engineering design. Background Technology
[0002] Dam slope protection structures are key structures in water conservancy and hydropower projects that protect the stability of dam slopes and prevent water erosion and soil erosion. Their design must take into account the dam type, geological conditions, water flow characteristics and ecological requirements, and select appropriate materials and types.
[0003] The existing dam slope protection structure is relatively simple. When faced with strong water flow impact, the slope protection has limited erosion resistance and cannot effectively buffer the stress caused by deformation. It is easy for the slope protection blocks to loosen and fall off, resulting in low stability, affecting the overall safety of the dam. The drainage function is not perfect, requiring frequent maintenance and replacement, which is inconvenient to operate and increases the project maintenance cost.
[0004] Therefore, in view of the problems of limited scour resistance, low stability, and inconvenient maintenance and replacement of existing dam slope protection structures, a dam slope protection structure based on water conservancy and hydropower engineering design can be designed. Utility Model Content
[0005] In order to overcome the problems of limited scour resistance, low stability, and inconvenient maintenance and replacement of existing dam slope protection structures.
[0006] The technical solution of this utility model is as follows: a dam slope protection structure for water conservancy and hydropower engineering design, including a dam body; it also includes slope protection blocks and limiting blocks. A slope protection support frame is fixedly connected to the upper end of the dam body. A protective net is fixedly connected inside the slope protection support frame. A slope protection block is set inside the slope protection support frame and above the protective net. A spring is fixedly connected to the outer side of the slope protection block. A limiting block is fixedly connected to the end of the spring away from the slope protection block. A limiting groove is opened on the outer side of the slope protection block. A fixing pile is set inside the slope protection block. A drainage pipe is fixedly connected to the front side of the upper end of the dam body. A water storage tank is opened inside the dam body. A sprinkler head is set at the upper end of the slope protection block.
[0007] Preferably, multiple sets of slope protection blocks are sequentially placed inside the slope protection support frame, and limiting blocks are embedded in the limiting grooves of adjacent slope protection blocks to connect multiple slope protection blocks. Fixing piles are sequentially passed through the slope protection blocks and protective netting and penetrate deep into the dam body, so that the slope protection blocks are firmly connected to the dam body. When water flows and impacts the slope, the spring absorbs and buffers the impact force of the water flow. The displacement of the slope protection blocks is limited by the cooperation of the limiting blocks and limiting grooves. At the same time, the water flows through the slope protection blocks into the water storage tank for storage, and the water is sprayed out through the sprinkler heads to spray and irrigate the plants planted inside the slope protection blocks.
[0008] Preferably, the protective net is made of steel wire, and a reverse filter drainage layer is fixedly connected to the lower end of the protective net.
[0009] Preferably, the slope protection blocks are made of concrete and have a hexagonal structure. Drainage holes are evenly distributed at the bottom of the slope protection blocks, and plants can be planted inside the slope protection blocks.
[0010] Preferably, an installation hole is provided in the middle of the lower end of the slope protection block, and the fixing pile is fixedly connected to the installation hole.
[0011] Preferably, the limiting block is made of rubber damping material and has a trapezoidal structure. Three limiting blocks are arranged in a ring array, and the limiting blocks and limiting grooves are distributed at intervals and are adapted to each other.
[0012] Preferably, four drainage pipes are installed at equal intervals. The upper end of the drainage pipe is connected to the slope protection block, and the lower end of the drainage pipe is fixedly connected to a manifold. The lower end of the manifold is fixedly connected to the water storage tank.
[0013] Preferably, a water pump is fixedly connected inside the water storage tank, and a T-shaped spray pipe is fixedly connected to the upper end of the water pump. The T-shaped spray pipe extends to the outside of the limiting block and is fixedly connected to two spray heads.
[0014] The beneficial effects of this utility model are: This dam slope protection structure, designed for water conservancy and hydropower engineering, utilizes slope protection blocks and limiting blocks. Multiple sets of slope protection blocks are sequentially placed inside the slope protection support frame, and the limiting blocks are embedded in the limiting grooves of adjacent slope protection blocks to connect multiple slope protection blocks. Fixed piles are sequentially passed through the slope protection blocks and protective netting and penetrate deep into the dam body, ensuring a firm connection between the slope protection blocks and the dam body. This facilitates construction and maintenance, improves the stability of the slope protection. When water flows against the slope, springs absorb and buffer the impact force of the water flow, and the cooperation between the limiting blocks and limiting grooves restricts the displacement of the slope protection blocks, reducing damage and detachment of the slope protection blocks and improving erosion resistance. At the same time, water flows through the slope protection blocks into a reservoir for storage, and is sprayed out through sprinkler heads to irrigate the plants planted inside the slope protection blocks, realizing the recycling of water resources.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0018] Please see Figures 1-5 This utility model provides an embodiment of a dam slope protection structure for water conservancy and hydropower engineering design, including a dam body 1; it also includes slope protection blocks 4 and limiting blocks 6. A slope protection support frame 2 is fixedly connected to the upper end of the dam body 1. A protective net 3 is fixedly connected inside the slope protection support frame 2. A slope protection block 4 is set inside the slope protection support frame 2 and above the protective net 3. A spring 5 is fixedly connected to the outer side of the slope protection block 4. A limiting block 6 is fixedly connected to the end of the spring 5 away from the slope protection block 4. A limiting groove 7 is opened on the outer side of the slope protection block 4. A fixing pile 8 is set inside the slope protection block 4. A drainage pipe 9 is fixedly connected to the front side of the upper end of the dam body 1. A water storage tank 10 is opened inside the dam body 1. A sprinkler head 11 is set at the upper end of the slope protection block 4. Multiple sets of slope protection blocks 4 are sequentially placed inside the slope protection support frame 2. Limiting blocks 6 are embedded in the limiting grooves 7 of adjacent slope protection blocks 4 to connect multiple slope protection blocks 4. Fixing piles 8 are sequentially passed through the slope protection blocks 4 and the protective net 3 and penetrate deep into the dam body 1. The slope protection blocks 4 are firmly connected to the dam body 1, making construction and maintenance convenient and improving the stability of the slope. When water flows and impacts the slope, the spring 5 absorbs and buffers the impact force of the water flow. The displacement of the slope protection blocks 4 is limited by the cooperation of the limiting blocks 6 and the limiting grooves 7, reducing the damage and fall-off of the slope protection blocks 4 and improving the erosion resistance. At the same time, the water flows through the slope protection blocks 4 into the water storage tank 10 for storage, and the water is sprayed out through the sprinkler heads 11 to irrigate the plants planted inside the slope protection blocks 4, realizing the recycling of water resources.
[0019] Please see Figure 2 , Figure 3 and Figure 4In this embodiment, the protective net 3 is made of steel wire, and a reverse filter drainage layer 12 is fixedly connected to the lower end of the protective net 3. The protective net 3 improves the stability of the entire slope protection structure. The reverse filter drainage layer 12 effectively filters the mud and sand in the water flow, ensuring smooth drainage and preventing the loss of bottom soil. The slope protection block 4 is made of concrete and has a hexagonal structure. Drainage holes are evenly opened at the lower end of the slope protection block 4. Plants can be planted inside the slope protection block 4, which reduces soil erosion. The drainage holes collect and store the water generated by the water flow impacting the slope protection block 4. An installation hole 13 is opened in the middle of the lower end of the slope protection block 4. The fixing pile 8 is fixedly connected to the installation hole 13. The fixing pile 8 is inserted into the installation hole 13 and penetrates into the interior of the dam body 1, so that the slope protection block 4 is firmly connected to the dam body 1.
[0020] Please see Figure 1 , Figure 4 and Figure 5 In this embodiment, the limiting block 6 is made of rubber damping material and has a trapezoidal structure. Three limiting blocks 6 are arranged in a circular array. The limiting blocks 6 and limiting grooves 7 are spaced apart and adapted to each other. The limiting blocks 6 are embedded in the limiting grooves 7 of adjacent slope protection blocks 4, thus connecting multiple slope protection blocks 4. Four drainage pipes 9 are evenly spaced. The upper end of each drainage pipe 9 is connected to a slope protection block 4, and the lower end of each drainage pipe 9 is fixedly connected to a manifold 14. The lower end of 4 is fixedly connected to the water storage tank 10. Water in the drain pipe 9 flows into the water storage tank 10 through the manifold 14 for storage. A water pump 15 is fixedly connected inside the water storage tank 10. A T-shaped spray pipe 16 is fixedly connected to the upper end of the water pump 15. The T-shaped spray pipe 16 extends to the outside of the limiting block 6 and is fixedly connected to two spray heads 11. The water pump 15 transports water in the water storage tank 10 to the spray heads 11 through the T-shaped spray pipe 16 to spray and irrigate the plants, thereby realizing the recycling of water resources.
[0021] During operation, multiple sets of slope protection blocks 4 are sequentially placed inside the slope protection support frame 2. The limiting block 6 is embedded in the limiting groove 7 of the adjacent slope protection block 4 to connect multiple slope protection blocks 4. The fixing pile 8 is inserted into the installation hole 13 and extends deep into the dam body 1, so that the slope protection block 4 is firmly connected to the dam body 1. When the water flow impacts the slope, the spring 5 absorbs and buffers the impact force of the water flow. The displacement of the slope protection block 4 is limited by the cooperation of the limiting block 6 and the limiting groove 7, which reduces the damage and fall-off of the slope protection block 4 and improves the erosion resistance. At the same time, the water flow flows from the drainage hole of the slope protection block 4 into the water storage tank 10 through the manifold 14 for storage. The water pump 15 delivers the water in the water storage tank 10 to the sprinkler head 11 through the T-shaped sprinkler pipe 16 to spray and irrigate the plants planted inside the slope protection block 4.
[0022] Through the above steps, the limiting block 6 connects multiple slope protection blocks 4, making construction and maintenance convenient and improving the stability of the slope. The spring 5 absorbs and buffers the impact force of water flow. The cooperation between the limiting block 6 and the limiting groove 7 restricts the displacement of the slope protection blocks 4, reduces damage and detachment of the slope protection blocks 4, and improves the scour resistance. This solves the problems of limited scour resistance, low stability, and inconvenient maintenance and replacement operations of existing dam slope protection structures.
