Description

Technical Field

[0001] The utility model relates to the technical field of ecological restoration, and more specifically, the utility model relates to an ecological restoration structure for a riverbank slope. Background Technique

[0002] The so-called ecological restoration refers to stopping human interference in the ecosystem to reduce the load pressure, relying on the self-regulation ability and self-organization ability of the ecosystem to evolve it in an orderly direction, or using the self-recovery ability of the ecosystem and supplementing it with artificial measures to gradually restore the damaged ecosystem or make the ecosystem develop in a virtuous cycle direction. During the flood season, due to the scouring caused by the rising river water, the water and soil loss of the riverbank slope is serious, destroying the ecological balance of the riverbank slope. The garbage on the flat ground beside the river will fall to the riverbank slope and into the river, further destroying the ecological balance of the riverbank slope.

[0003] The utility model patent with the patent publication number CN217078631U discloses an ecological restoration structure for a riverbank slope, belonging to the technical field of ecological restoration. It includes a first bank slope, a second bank slope, a flat ground, and an intermediate ladder layer located between the first bank slope and the second bank slope. A protection component is installed at the edge of the flat ground close to the first bank slope. Ecological restoration components are arranged at the tops of the first bank slope and the second bank slope. A stone wall layer is arranged at the top of the intermediate ladder layer and on the side close to the second bank slope. The top of the ecological restoration component of the first bank slope is connected with a vegetation net. The top of the ecological restoration component of the second bank slope is connected with a grid-shaped concrete reinforcement layer, and the top of the concrete reinforcement layer is also connected with a vegetation net. The tops of the two vegetation nets are both covered with a soil layer, which can provide a good growth environment for plants, facilitate the restoration of the ecological environment of the first bank slope and the second bank slope, and reduce the impact of the garbage on the flat ground on the ecological environment of the first bank slope and the second bank slope.

[0004] However, when this structure is actually used, since the soil layer covers the concrete, the rooting depth of the vegetation is limited when the vegetation takes root, resulting in low soil fixation ability. When a flood phenomenon occurs, the soil layer and vegetation above the concrete layer are easily washed away together. Therefore, an ecological restoration structure for a riverbank slope is proposed. Content of the Utility Model

[0005] In order to overcome the above-mentioned defects of the prior art, the utility model provides an ecological restoration structure for a riverbank slope to solve the problems raised in the above-mentioned background technique.

[0006] To achieve the above object, the present utility model provides the following technical solution: An ecological restoration structure for a riverbank slope, including a river channel protection board. Inside the river channel protection board, there is a gravel layer. At the top of the gravel layer, there is a top board connected to the river channel protection board. On the top board, there is a blocking member. The top board is connected to a plurality of partition boards. A plurality of the partition boards are jointly connected to a fixing beam. At the bottom of the fixing beam, there are a plurality of strengthening beams. Between adjacent partition boards, there is a soil layer. On the top of the soil layer, there is a filter screen layer. On the top of the filter screen layer, there are a first slope protection board and a second slope protection board. Inside the first slope protection board, there is a blocking assembly.

[0007] By arranging strengthening beams at the bottom of the fixing beam, the fixing effect of the fixing beam can be improved, and in cooperation with the connection between the partition boards and the river channel protection board, the fixing property of the river channel protection board can be improved, thereby enhancing the impact resistance of the river channel protection board. The partition boards divide the soil layer into multiple areas, which can prevent the situation where when serious soil erosion occurs in a single area, other soils will follow and be lost, thus improving the soil fixation effect. During rainy weather, the rainwater can gather above the top board under the diversion of the first slope protection board and the second slope protection board, flow into the gravel layer through the leakage holes, and then flow into the river through the overflow holes opened on the river channel protection board, improving the convenience of drainage. During the drainage process, the filter cotton layer can filter the soil carried in the water to prevent it from entering the river. When the riverbank slope is relatively dry, the water in the river can also infiltrate through the overflow ports, thereby ensuring that the vegetation can absorb water.

[0008] Preferably, a filter cotton layer is arranged between the gravel layer and the soil layer, and the top of the filter cotton layer is arranged between the gravel layer and the top board.

[0009] Preferably, the top board is evenly provided with leakage holes, and the leakage holes are vertically arranged above the filter cotton layer.

[0010] Preferably, the river channel protection board has an inclined structure, and the river channel protection board is evenly provided with overflow holes.

[0011] Preferably, both the first slope protection board and the second slope protection board are provided with planting grooves. Among them, fixing parts are embedded on the inner wall of the planting groove opened on the first slope protection board, and the fixing parts are connected and cooperated with the blocking assembly.

[0012] Preferably, the blocking assembly includes an annular protection net, fixing nails, an inner support ring, and an outer support plate. The inner ring of the annular protection net is connected to the inner support ring, the outer ring of the annular protection net is provided with the outer support plate, and a plurality of fixing nails inserted and cooperated with the fixing parts are arranged at the bottom of the outer support plate.

[0013] The technical effects and advantages of the present utility model:

[0014] 1. By providing a river channel protection board, a gravel layer, a blocking member, a fixing beam, a strengthening beam, and a filter screen layer, compared with the prior art, by dividing the soil on the river bank slope into multiple areas, it is possible to avoid the situation where the soil in a single area is washed away due to a strong impact and causes the loss of other areas, thereby improving the soil fixation effect on the bank slope. At the same time, it is convenient for drainage, and during the drainage process, filtration can be carried out to reduce the soil entrainment generated during the drainage process.

[0015] 2. By providing a first slope protection baffle, a blocking assembly, and a fixing member, compared with the prior art, the planting groove opened on the first slope protection baffle can plant larger trees, and after planting the trees, the turned-up soil is covered by the blocking assembly, thereby avoiding the loss of the turned-up soil during planting, and further improving the soil fixation effect.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As shown in the attached Figures 1-5An ecological restoration structure for a riverbank slope is shown, including a river channel protection board 1. Inside the river channel protection board 1, there is a gravel layer 2. At the top of the gravel layer 2, there is a top board 11 connected to the river channel protection board 1. On the top board 11, there is a blocking member 3. The top board 11 is connected to a plurality of partition boards 4. The plurality of partition boards 4 are jointly connected to a fixing beam 5. At the bottom of the fixing beam 5, there are a plurality of strengthening beams 6. Between adjacent partition boards 4, there is a soil layer. On the top of the soil layer, there is a filter screen layer 7. On the top of the filter screen layer 7, there are a first slope protection board 8 and a second slope protection board 9. Inside the first slope protection board 8, there is a blocking assembly 10. Between the gravel layer 2 and the soil layer, there is a filter cotton layer. The top of the filter cotton layer is arranged between the gravel layer 2 and the top board 11. On the top board 11, there are evenly arranged leakage holes 12. The leakage holes 12 are vertically arranged above the filter cotton layer. The river channel protection board 1 is of an inclined structure, and there are evenly arranged water overflow holes on the river channel protection board 1. The first slope protection board 8 and the second slope protection board 9 are both provided with planting grooves. Among them, on the inner wall of the planting groove opened on the first slope protection board 8, there is a pre-embedded fixing member 13. The fixing member 13 is connected and cooperated with the blocking assembly 10.

[0024] During specific implementation, by arranging the strengthening beams 6 at the bottom of the fixing beam 5, the fixing effect of the fixing beam 5 can be improved, and in cooperation with the connection between the partition boards 4 and the river channel protection board 1, the fixing property of the river channel protection board 1 can be improved, thereby improving the impact resistance of the river channel protection board 1. The partition boards 4 divide the soil layer into multiple areas, which can prevent the situation that when a single area has serious soil loss, other soils will follow and be lost, thus improving the soil fixation effect. In rainy weather, the rainwater can gather above the top board 11 under the diversion of the first slope protection board 8 and the second slope protection board 9, flow into the gravel layer 2 through the leakage holes 12, and then flow into the river through the water overflow holes opened on the river channel protection board 1, improving the convenience of drainage. During the drainage process, the filter cotton layer can filter the soil carried in the water to avoid entering the river.
