Description

Technical Field

[0001] This utility model belongs to the field of ecological bank protection technology, and in particular relates to an ecological bank protection structure suitable for the ecological clean watershed river management. Background Technology

[0002] River management, as the core of small watershed management, requires its bank protection structures to not only possess traditional flood control and bank stabilization functions, but also to take into account ecological restoration and environmental beautification. Traditional bank protection structures mostly use hard materials such as concrete and masonry, which, although structurally stable, sever the connection between water and land ecosystems, damage the natural landscape and biodiversity of rivers, and are difficult to meet the construction requirements of ecologically clean small watersheds.

[0003] Existing ecological bank protection technologies, such as ecological block bank protection, have improved the ecological environment to a certain extent. However, traditional block structures have poor overall integrity and are prone to displacement or damage under uneven foundation settlement or long-term water erosion, so their stability needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to provide an ecological bank protection structure suitable for the ecological clean watershed river management, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An ecological revetment structure suitable for ecological clean watershed river management includes: an ecological wall set along the slope, the bottom of the ecological wall is provided with a foundation cushion layer, the top is provided with a top layer, the lower outer side of the ecological wall is in contact with the water body, and the inner side is provided with a soil cover layer and a filter layer in sequence. The ecological wall includes a bottom layer, a top layer, and a composite layer disposed between the bottom layer and the top layer. The bottom layer has a base pad layer at its bottom and a top layer has a pressing layer at its top. Both the bottom layer and the top layer include ecological blocks connected sequentially in a horizontal direction. The composite layer includes several ecological blocks and a connecting mesh. The connecting mesh is hexagonal, and its corners are connected to the ecological blocks and the ecological blocks, or to the ecological blocks and the ecological blocks, so that the composite layer has a honeycomb structure.

[0006] As a further improvement of this utility model, the composite layer also includes a plurality of connecting wires, which are disposed at the ends of the ecological wall for connecting the first ecological block and the second ecological block at the ends, or connecting the second ecological block and the second ecological block.

[0007] As a further improvement of this utility model, the outer side of the base pad is inclined upward and inward.

[0008] As a further improvement of this utility model, the filter layer includes a sand and gravel layer and a geotextile layer, wherein the sand and gravel layer is in contact with the cover soil layer, and the geotextile layer is in contact with the sand and gravel layer.

[0009] As a further improvement of this utility model, the inner side of the sand and gravel layer is provided with a plurality of longitudinally arranged grid plates, and the plurality of grid plates are horizontally arranged. The geotextile layer is shaped like a "┐", with its horizontal part located between the lower part of the grid plate and the slope soil, and its vertical part located inclined inside the sand and gravel layer between the slope soil.

[0010] As a further improvement of this utility model, both the first and second ecological blocks are provided with permeable grooves on their front surfaces and planting chambers on their upper parts; four fixing holes and two connecting holes are symmetrically provided on both sides of the planting chamber, wherein the connecting holes are located in the middle of the two fixing holes.

[0011] As a further improvement of this utility model, one end of the ecological block is provided with two protrusions, the two protrusions are symmetrically arranged, and the other end is provided with two slots that are adapted to the protrusions. Two adjacent ecological blocks are connected by adjacent bosses and slots.

[0012] As a further improvement of this utility model, the cross-section of the boss is in the shape of "]".

[0013] The beneficial effects of adopting the above technical solution are as follows: This utility model's ecological wall is constructed with a bottom layer, a top layer, and a middle composite layer. The composite layer includes ecological bricks and a connecting mesh, giving the composite layer a honeycomb structure. This distributes the load of a single brick evenly throughout the entire network system, greatly enhancing the integrity, compressive strength, and shear strength of the revetment. It effectively prevents chain failures caused by local damage and ensures the long-term stability of the structure under complex hydrological conditions.

[0014] In addition, the honeycomb structure forms a large number of regular, interconnected holes, which effectively promotes the material cycle and energy flow of the aquatic and terrestrial ecosystems, greatly enhances biodiversity, and truly achieves deep integration between the revetment structure and the ecosystem.

[0016] To better understand the purpose, structure, and function of this utility model, a clear and complete description of this utility model will be provided below in conjunction with the accompanying drawings.

[0017] like Figures 1-4 The diagram shows an ecological revetment structure suitable for the ecological clean watershed river management, which is set along the river slope and includes: an ecological wall set along the slope, the bottom of the ecological wall is provided with a foundation pad 1, the top is provided with a top layer 2, the side of the top layer 2 away from the water body is the bank top 20, the lower part of the outer side of the ecological wall is in contact with the water body, and the inner side is provided with a soil cover layer 3 and a filter layer in sequence, and the soil cover layer 3 is used for planting plants; The ecological wall includes a bottom layer 4, a top layer 5, and a composite layer disposed between the bottom layer 4 and the top layer 5. The bottom layer 4 has a base pad layer 1 at its bottom, and the top layer 5 has a pressing layer 2 at its top. Both the bottom layer 4 and the top layer 5 include ecological blocks 6 connected sequentially in the horizontal direction. The composite layer comprises several ecological blocks 7 and connecting nets 8. The connecting nets 8 are hexagonal, and their corners connect to ecological blocks 6 and 7, or to ecological blocks 7 and 7, giving the composite layer a honeycomb structure. In traditional ecological block revetments, each block is isolated, and the impact of water flow acts directly on each block. The blocks rely on their own weight and friction with each other to resist the force. Once one block fails, the force will be transmitted in a chain reaction, potentially leading to large-scale landslides. By using ecological blocks + connecting nets 8, when pressure is applied to the soil between the blocks, the connecting nets 8 tighten, distributing the local force across the entire net surface and transmitting it to the blocks that serve as "anchor points" as well as the fixing points at the top and bottom of the slope, thus improving the integrity and shear strength of the soil.

[0018] To enhance the stability of the ends, the composite layer also includes several connecting wires 9, which are disposed at the ends of the ecological wall and are used to connect the first ecological block 6 and the second ecological block 7 at the ends, or to fix the first ecological block 6 and the second ecological block 7 with the second ecological block 7.

[0019] like Figure 3 and Figure 4As shown, both the first ecological block 6 and the second ecological block 7 have permeable grooves 14 on their front sides to allow water to flow through, and planting chambers 15 on their upper parts for planting plants and beautifying the landscape. Four fixing holes 16 and two connecting holes 17 are symmetrically arranged on both sides of the planting chambers 15. The fixing holes 16 are used to insert anchor rods such as steel bars to anchor the blocks to the slope. The connecting holes 17 are located between the two fixing holes 16 and are used to connect the ecological blocks to the connecting net 8 or connecting wire 9. Furthermore, one end of the first ecological block 6 has two protrusions 18, symmetrically arranged, and the other end has two slots 19 that fit the protrusions 18. Adjacent first ecological blocks 6 are connected by adjacent protrusions 18 and slots 19, which cooperate to achieve rapid and precise positioning and connection between the ecological blocks. Specifically, the cross-section of the protrusion 18 is "]".

[0020] In this embodiment, both the foundation pad 1 and the top layer 2 are made of concrete, with the foundation pad 1 being made of reinforced concrete. The outer side of the foundation pad 1 slopes upwards and inwards, utilizing the self-weight of the upper wall to generate an inward component force, effectively resisting the tendency of the wall to overturn outwards and enhancing anti-slip and anti-overturning stability. The top layer 2 applies downward pressure to the top layer 5 to prevent displacement.

[0021] The filter layer includes a sand and gravel layer 10 and a geotextile layer 11. The sand and gravel layer 10 is in contact with the topsoil layer 3, and the geotextile layer 11 is in contact with the sand and gravel layer 10. The geotextile layer 11 is used to prevent the loss of fine particles in the slope soil 13, while the sand and gravel layer 10 filters and ensures unobstructed seepage. Furthermore, the inner side of the sand and gravel layer 10 is provided with a plurality of longitudinally arranged grid plates 12, which are horizontally arranged. The geotextile layer 11 is in the shape of a "┐", with its horizontal part located between the lower part of the grid plate 12 and the slope soil 13, and its vertical part inclinedly located between the inner side of the sand and gravel layer 10 and the slope soil 13. The grid plate 12 strengthens the slope soil 13 and prevents the soil from sliding and failing.
