DETAILED DESCRIPTION
[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0020] This utility model provides a technical solution: such as Figures 1-4 As shown in this embodiment, an anti-erosion reservoir embankment protection structure includes a dam 11. A first anti-erosion groove 12 is formed on the top and bottom side of the dam 11. A concrete-reinforced gabion 13 is installed inside the first anti-erosion groove 12. An arc-shaped stone slab 14 is placed on top of the concrete-reinforced gabion 13. The concrete-reinforced gabion 13 is poured into the first anti-erosion groove 12, and the arc-shaped stone slab 14 is poured on top of the concrete-reinforced gabion 13. Multiple permeable grooves 15 are arrayed through the top of the arc-shaped stone slab 14. The concrete-reinforced gabion 13 is provided with several load-bearing stones 16. A second anti-erosion groove 17 is formed above the first anti-erosion groove 12 on the top of the dam 11. A buffer mesh plate 18 is installed inside the second anti-erosion groove 17 and is fixedly connected to the top side of the inner wall of the second anti-erosion groove 17. A water-retaining mesh plate 19 is installed at the top of the dam 11 between the first scour channel 12 and the second scour channel 17. The water-retaining mesh plate 19 is fixedly connected to the top of the dam 11 between the first scour channel 12 and the second scour channel 17. A third scour channel 110 is opened above the top of the dam 11 near the second scour channel 17. A scour-resistant gabion 111 is installed inside the third scour channel 110. The scour-resistant gabion 111 is poured inside the third scour channel 110. A wave-breaking plate 112 is installed at the bottom of the dam 11 above the third scour channel 110. The wave-breaking plate 112 is fixedly connected to the bottom of the dam 11 above the third scour channel 110. Three drainage channels 114 are opened at the top of the dam 11 above the wave-breaking plate 112. Multiple drainage holes 113 are arrayed and penetrated on one side of the wave-breaking plate 112.
[0021] In this embodiment, when enhanced scour protection is required for the reservoir embankment, three scour-resistant grooves can be cut into the top slope of the embankment 11. The first scour-resistant groove 12 contains a concrete-reinforced gabion 13. The concrete-reinforced gabion 13 effectively resists the shear force and scouring effect of the water flow, preventing the soil inside the gabion from being carried away by the water flow and maintaining the integrity of the embankment slope. Adding several load-bearing stones 16 to the concrete-reinforced gabion 13 significantly increases the overall weight of the protective structure, improving its resistance to overturning and sliding. These load-bearing stones 16 serve as important structural supports, effectively resisting the horizontal and vertical forces of water flow on the protective structure, thus ensuring the entire structure is more firmly rooted in the embankment. Furthermore, the top of the concrete-reinforced gabion 13 is topped with an arc-shaped stone slab 14 featuring multiple permeable channels 15, allowing water to flow smoothly over the slab surface and reducing the direct impact and uplift effect on the stones. This ensures the load-bearing stones 16 remain stable. When the water level continues to rise, the water-blocking mesh 19 can divert the rapid water flow. By dispersing the water flow, the originally concentrated water energy is distributed over a wider area, reducing the water impact force per unit area. This reduces the scouring intensity of the water flow at a single point on the embankment, effectively protecting the embankment soil and protective structure. A portion of the water passing through the water-retaining mesh 19 will cover the buffer mesh 18, further mitigating the water impact and preventing damage to the embankment 11. As the water level rises, the water flow velocity and impact force increase, and the erosion-resistant gabions 111 fill the third erosion-resistant... The gabion 110 has a compact structure that can withstand the direct impact of large water flows. The stones in the gabion are interlocked and can effectively disperse the force of the water flow under the impact of the water flow, reducing the impact force on a single stone and keeping the entire gabion structure stable. This prevents the gabion from being washed away or displaced by the water flow, thus protecting the embankment slope from excessive erosion by the water flow. The wave baffle 112 can block the splashing waves, and the drainage channel 114 can divert and disperse some water, preventing water from concentrating and causing pressure damage to the embankment 11.
[0022] This utility model provides an anti-erosion reservoir embankment protection structure, the specific working principle of which is as follows:
[0023] To effectively enhance the scour resistance of the reservoir embankment, three scour-resistant channels can be installed on the top slope of the embankment 11. The first scour-resistant channel is filled with reinforced concrete gabions 13, which can strongly resist the shearing and scouring of the water flow, prevent soil loss, and maintain the integrity of the embankment slope. Load-bearing stones 16 are added to the gabions to enhance stability. The top is covered with an arc-shaped stone slab 14 with permeable channels 15 to ensure smooth water flow, reduce the impact on the stones, and ensure the stability of the load-bearing stones 16. When the water level rises, the water-blocking mesh 19 can disperse the rapid flow, and some of the water flow covers the buffer mesh 18 to further reduce the impact force and protect the embankment 11. In the third scour-resistant channel, the scour-resistant gabions 111 are interlocked with each other under the impact of the water flow, disperse the force of the water flow, and maintain structural stability. In addition, the wave-breaking plate 112 can effectively block the splashing waves and divert and disperse the water through the drainage channel 114, thereby comprehensively enhancing the scour resistance of the reservoir embankment.
