[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model. Example

[0022] like Figures 1 to 4 As shown, this utility model provides a dam slope protection structure, including a dam body. The dam body has a base layer 11, a permeable layer, and a vegetation layer 14. The base layer 11 provides fundamental support for the entire slope protection structure. Slope protection components are installed on the permeable layer. The permeable layer, consisting of a gravel layer 12 and a geotextile layer 13, allows water to permeate and filter from the slope, preventing soil erosion and providing a suitable environment for vegetation. The slope protection components include multiple sets of fixing frames 15, each containing the vegetation layer 14. The fixing frames 15 secure the vegetation layer 14, preventing displacement due to external forces and enhancing slope stability. The multiple sets of fixing frames 15 are connected to the dam body via multiple sets of fixing anchors 16. The fixing anchors 16 secure the fixing frames 15 to the dam body, ensuring the entire slope protection component is connected to the dam body and improving structural stability. Multiple sets of fixed frames 15 are connected by connectors, which allow them to form a unified whole, working together to protect the slope and enhance the overall structural strength. A drainage system is installed below each fixed frame 15 to drain accumulated water near the frames, preventing damage to the slope protection structure. The drainage system includes a guide pipe 23; a water collection trough 26 is located within the base layer 11, and the guide pipe 23 connects to the water collection trough 26. Through the guide pipe 23 and the water collection trough 26, water seeping down the slope is collected and directed to the water collection trough 26 for centralized treatment, preventing water accumulation on the slope.

[0023] like Figure 2As shown, the slope protection component also includes a slope protection net 27, which covers the surface of the vegetation layer 14. The slope protection net 27 is connected to the fixing frame 15 via clips. The slope protection net 27 and clips further protect the vegetation layer 14, preventing damage from external forces. The clips also facilitate installation and disassembly. Fixing anchors 16 are located at the four bottom corners of the fixing frame 15. The fixing anchors 16 at the four bottom corners of the fixing frame 15 allow for the installation of the fixing frame 15.

[0024] The fixed frame 15 contains multiple sets of planting boards 28. These planting boards 28 provide independent and suitable planting spaces for vegetation, facilitating its orderly growth. Each set of planting boards 28 has a slot 29 and a locking block 31. The locking block 31 on each planting board 28 engages with the slot 29 on an adjacent set of planting boards 28. The slots 29 and locking blocks 31 allow the multiple sets of planting boards 28 to connect together, forming a unified structure, enhancing the stability between the planting boards 28 and preventing them from shifting within the fixed frame 15.

[0025] like Figure 1 , 2 As shown, the permeable layer consists of a gravel layer 12 and a geotextile layer 13. The geotextile layer 13 is laid between the gravel layer 12 and the vegetation layer 14. Through the arrangement of the gravel layer 12 and the geotextile layer 13, drainage can be achieved through the pores of the gravel layer 12, while the geotextile layer 13 filters sediment, preventing soil particles from being lost with water, thus ensuring both water permeability and soil stabilization. The vegetation layer 14 is placed within the planting board 28. This placement of the vegetation layer 14 within the planting board 28 allows vegetation to grow in a relatively stable environment, facilitating management and maintenance, while also enhancing the slope protection effect.

[0026] like Figure 2 , 3As shown, the connector includes a fixed plate 17 and an adjusting rod 18. The fixed plate 17 and adjusting rod 18 allow the adjusting rod 18 to operate the fixed plate 17, thus adjusting the connector. A lead screw 22 passes through one side of the fixed plate 17. The lead screw 22 works in conjunction with the adjusting rod 18 to convert the rotational motion of the adjusting rod 18 into the linear motion of the lead screw 22, thereby controlling the clamping plate 21. A groove 19 is formed at the bottom of the fixed plate 17, and two sets of clamping plates 21 are arranged within the groove 19. The groove 19 and clamping plates 21 allow the clamping plates 21 to move within the groove 19, facilitating the clamping or loosening of the fixed frame 15. A clamping plate 21 is fitted onto a lead screw 22, which is connected to an adjusting rod 18. This arrangement allows the lead screw 22 to rotate via the adjusting rod 18, thereby controlling the movement of the clamping plate 21 and achieving a secure connection to the fixed frame 15. The fixed frame 15 has a fixing groove, within which the clamping plate 21 is engaged. This fixing groove and clamping plate 21 enhance the stability of the connection between the fixed frames 15.

[0027] like Figure 2 , 4 As shown, the drainage assembly also includes a filter plate 24 and a baffle plate 25. The filter plate 24 is located at the outlet of the guide pipe 23. The filter plate 24 prevents debris from entering the guide pipe 23, avoiding pipe blockage and ensuring smooth drainage. The baffle plate 25 is located below the fixed frame 15 and is inclined. The higher end of the baffle plate 25 is connected to the bottom of the fixed frame 15, and the lower end faces the guide pipe 23. The baffle plate 25 guides water near the fixed frame 15 to the guide pipe 23, improving drainage efficiency and simultaneously blocking some of the water flow from directly impacting the bottom of the fixed frame 15.

[0028] The guide pipe 23 has multiple sets of water inlets, and the outer ring of the guide pipe 23 is wrapped with a drain cloth 32. By setting multiple sets of water inlets and drain cloth 32, the water inlet area of ​​the guide pipe 23 can be increased, and the water collection efficiency can be improved. The drain cloth 32 further filters impurities in the water, ensuring that the water flowing into the guide pipe 23 is relatively clean.

[0029] The specific usage and function of this embodiment are as follows:

[0030] First, a base layer 11 is constructed on the dam body. The base layer 11 provides a stable foundation support for the entire slope protection structure, ensuring the stable laying of subsequent structural layers. A permeable layer consisting of a crushed stone layer 12 and a geotextile layer 13 is laid on top of the base layer 11. The crushed stone layer 12 has good permeability, allowing water to quickly infiltrate the slope. The geotextile layer 13 is laid between the crushed stone layer 12 and the vegetation layer 14, filtering sediment and preventing soil particles from being washed away by water, thus achieving soil stabilization while ensuring water permeability. The fixed frame 15 and vegetation layer 14 are then installed: multiple sets of fixed frames 15 with vegetation layers 14 are placed on the permeable layer. Multiple planting boards 28 are installed within the fixed frame 15. The slots 29 and blocks 31 on the planting boards 28 cooperate with each other. The blocks 31 are engaged in the slots 29 of adjacent planting boards 28, connecting the planting boards 28 into a whole, providing independent and orderly planting space for vegetation, facilitating vegetation growth. The vegetation layer 14 is placed within the planting board 28, growing in a relatively stable environment and enhancing the slope protection effect. Multiple sets of fixed frames 15 are fixed to the dam body via fixed anchors 16, which are located at the four bottom corners of the fixed frames 15, stabilizing them from the bottom and ensuring the entire slope protection assembly is connected to the dam body, thus improving structural stability. Simultaneously, the multiple sets of fixed frames 15 are connected by connectors, including a fixed plate 17, an adjusting rod 18, a threaded rod 22, a sliding groove 19, and a clamping plate 21. The adjusting rod 18 passes through the top of the fixed plate 17, and the threaded rod 22 passes through one side. A clamping plate 21 is located in the bottom sliding groove 19, and the clamping plate 21 is fitted onto the threaded rod 22, which is connected to the adjusting rod 18. In use, rotating the adjusting rod 18 causes the threaded rod 22 to rotate, converting the rotational motion of the adjusting rod 18 into linear motion, thereby controlling the movement of the clamping plate 21 within the sliding groove 19. The fixed frame 15 has a fixing groove, and the clamping plate 21 is snapped into the fixing groove, so that multiple sets of fixed frames 15 form a whole, working together to protect the slope and enhance the overall structural strength. A slope protection net 27 is covered on the surface of the vegetation layer 14. The slope protection net 27 is connected to the fixed frame 15 by clips. This arrangement further protects the vegetation layer 14 from damage caused by external forces such as water flow impact and animal grazing, and the clip connection facilitates installation and disassembly. A drainage assembly is installed below the fixed frame 15, including a guide pipe 23, a filter plate 24, and a water-blocking plate 25. The water-blocking plate 25 is located below the fixed frame 15 and is inclined, with its higher end connected to the bottom of the fixed frame 15 and its lower end facing the guide pipe 23. Its function is to guide water near the fixed frame 15 to the guide pipe 23, improving drainage efficiency, while simultaneously blocking some of the water flow from directly impacting the bottom of the fixed frame 15. The guide pipe 23 has multiple water inlets to increase the water inlet area and improve water collection efficiency. The drain cloth 32 wrapped around its outer ring further filters impurities in the water, ensuring that the water flowing into the guide pipe 23 is relatively clean. The filter plate 24 is located at the outlet of the guide pipe 23 to prevent debris from entering the guide pipe 23, avoid pipe blockage, and ensure smooth drainage.When water accumulates on the slope, it seeps down through the permeable layer, is guided by the baffle plate 25 to the diversion pipe 23, and then introduced into the collection trough 26 in the base layer 11. The collection trough 26 facilitates the unified treatment of the seeping water, prevents water accumulation on the slope, and avoids landslides and collapses caused by excessive soil moisture due to water accumulation, thus ensuring the stability and safety of the dam.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
