Description

Technical Field

[0001] This utility model relates to the field of revetment technology, and in particular to a multi-layered riverbank revetment with wooden piles. Background Technology

[0002] While common ecological revetments currently use materials such as wooden piles and vegetation, they still suffer from the following shortcomings: 1. Simple structure: Most use only a single layer of wooden piles or simple stacking, which has weak resistance to water flow impact and is prone to loosening and collapse due to erosion; 2. Functional fragmentation: They are not designed in layers to account for water level fluctuations in river channels (such as rapid water flow during the high-water season and low water level during the low-water season), and cannot take into account the protection and ecological needs under different hydrological conditions; 3. Insufficient ecological benefits: There is a lack of systematic planning for the habitat space of aquatic organisms (such as fish and benthic animals), and the vegetation configuration is not well coordinated with the wooden pile structure; 4. Low landscape coordination: The arrangement of wooden piles is rigid and regular, and the integration with the surrounding natural landscape is insufficient.

[0003] Based on the above reasons, this utility model designs a multi-layered riverbank revetment with wooden piles. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a multi-layered riverbank revetment. By setting up a double-layered protection of the water-blocking area and the revetment area, the riverbank's resistance to water flow impact is significantly improved. Furthermore, the water-blocking area and the revetment area are filled with gravel and loam and planted with vegetation, providing a continuous ecological corridor for fish spawning, benthic animals to inhabit, amphibians to migrate, and birds to forage.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: This utility model discloses a multi-layered riverbank revetment with wooden piles, including a water-retaining area and a revetment area. The revetment area is located on the outer side of the riverbank, and an impermeable membrane is provided between the inner side of the revetment area and the outer side of the riverbank. The water-retaining area is located in the river channel outside the revetment area. The water-retaining area includes a first wooden pile, a gravel layer, a soil layer, and submerged plants. The bottom end of the first wooden pile has a conical structure and is inserted into the bottom of the river channel. Several first wooden piles form a closed-loop first pile group. The bottom of the inner wall of the first pile group is covered with the gravel layer of the water-retaining area. The soil layer of the water-retaining area is laid on top of the gravel layer. The submerged plants are planted on top of the soil layer of the water-retaining area.

[0006] The first group of wooden piles is a plum blossom-shaped structure formed by connecting five identical arc-shaped structures end to end, and the top of the first wooden pile is below the normal water level.

[0007] The revetment area includes second wooden piles, a gravel layer, a soil layer, and trees. A number of second wooden piles form a square frame structure of the second pile group. The bottom of the inner wall of the second pile group is covered with the gravel layer. The soil layer is laid on top of the gravel layer. The trees are planted on top of the soil layer.

[0008] The second wooden stake at the first end and the second wooden stake at the last end of the second wooden stake group are provided with tensioning mechanisms for fixing the geomembrane.

[0009] The tensioning mechanism includes a transverse plate, a longitudinal plate, a hook-shaped component, a tensioning bolt, a tensioning nut, and a clamping component. The front wall of the transverse plate is fixed to the rear wall of the second wooden stake, and the outer end of the transverse plate is fixed to the middle of the inner wall of the longitudinal plate. The front inner wall of the longitudinal plate is connected to the outer wall of the second wooden stake. The hook-shaped component includes a sliding plate, a transition plate, and an inclined plate. The front wall of the sliding plate can slide in cooperation with the rear wall of the transverse plate. The outer end of the sliding plate is connected to the front end of the arc-shaped transition plate, and the rear end of the transition plate is connected to the front end of the inclined plate. The rear end of the inclined plate is inclined outward. The inner end of the tensioning bolt is connected to the rear side of the outer wall of the inclined plate, and the outer end of the tensioning bolt passes through the rear side wall of the longitudinal plate and is threaded to the tensioning nut. The inner end of the tensioning bolt is perpendicular to the outer wall of the inclined plate. The clamping component is used to clamp both ends of the geomembrane, and the front wall of the clamping component is fixedly connected to the rear wall of the sliding plate.

[0010] The hook-shaped component also includes a tensioning block, which is made of rubber and has a ring-shaped circumferential cross-section and a triangular axial cross-section. Its inner wall is parallel to the longitudinal plate, and the inner wall of the tensioning block is fixed to the outer wall of the longitudinal plate. The outer wall of the tensioning block is parallel to the inclined plate, and the tensioning block has a through hole in its axial direction for the tensioning bolt to pass through.

[0011] The clamping component includes a front clamping plate, a rear clamping plate, a clamping bolt, and a clamping nut. The front wall of the front clamping plate is fixedly connected to the rear wall of the sliding plate. The rear clamping plate has the same shape as the front clamping plate and is arranged parallel to the rear side of the front clamping plate. The front end of the clamping bolt passes through the middle of the rear clamping plate and is fixedly connected to the middle of the rear wall of the front clamping plate. The rear end of the clamping bolt is connected to the clamping nut by a thread.

Detailed Implementation

[0020] The present invention will be further described below:

[0021] Please see Figure 1-4 ,

[0022] This utility model discloses a multi-layered riverbank revetment with wooden piles, comprising a water-retaining area 1 and a revetment area 2. The revetment area 2 is located on the outer side of the riverbank 3, and an impermeable membrane 4 is provided between the inner side of the revetment area 2 and the outer side of the riverbank 3. The water-retaining area 1 is located in the river channel outside the revetment area 2. The water-retaining area 1 includes first wooden piles 11, a gravel layer 12, a soil layer 13, and submerged plants 14. The bottom end of the first wooden piles 11 is conical and inserted into the bottom of the river channel. A plurality of first wooden piles 11 form a closed loop structure. The first pile group has a gravel layer 12 for the water-retaining area laid at the bottom of its inner wall, and a soil layer 13 for the water-retaining area laid on top of the gravel layer 12. The submerged plants 14 are planted on top of the soil layer 13 for the water-retaining area. This utility model significantly improves the resistance of the riverbank 3 to water flow impact by setting up a double-layer protection of the water-retaining area 1 and the revetment area 2. The water-retaining area 1 and the revetment area 2 are filled with gravel and soil and planted with plants, providing a continuous ecological corridor for fish spawning, benthic animals to inhabit, amphibians to migrate and birds to forage.

[0023] Furthermore, the first pile group is a plum blossom-shaped structure formed by five identical arc-shaped structures connected end to end. Alternatively, a natural layout scheme such as a triangular pattern can be adopted, which is more aesthetically pleasing and the overall appearance is in harmony with the natural form of the river channel. Preferably, the top of the first pile 11 is about 0.3m below the normal water level. The top of the first pile 11 being below the normal water level forms an underwater obstacle. When the water flows over it, it will generate flow around and tiny eddies, consuming the kinetic energy of the water and significantly reducing the near-shore flow velocity, thereby improving the resistance of the riverbank 3 to water flow impact.

[0024] Furthermore, the revetment area 2 includes second wooden piles 21, a gravel layer 22, a soil layer 23, and trees 24. Several second wooden piles 21 form a square-shaped second pile group. The bottom of the inner wall of the second pile group is covered with the gravel layer 22, and the soil layer 23 is laid on top of the gravel layer 22. The trees 24 are planted on top of the soil layer 23. Preferably, the height of the second wooden piles 21 is higher than the normal water level. When the water level exceeds the normal water level due to rainstorms, tides, or upstream flood discharge, the second wooden piles 21 form a continuous barrier to intercept the water flow, preventing floods from overflowing and eroding the riverbank behind; weakening waves and reducing the direct impact of water on the bank soil. Together with the first pile group, this improves the riverbank 3's resistance to water flow impact.

[0025] Furthermore, the first and last wooden stakes 21 on the inner side of the second wooden stake group are provided with tensioning mechanisms 5 for fixing the geomembrane 4, ensuring that both ends of the geomembrane 4 can be easily fixed to the inner side of the second wooden stake group, and that the geomembrane 4 can be appropriately tensioned to avoid wrinkling or forming air pockets when laying the geomembrane 4. The appropriate tension flattens the geomembrane 4, and then the middle part of the geomembrane 4 is fixed to the inner wall of the middle second wooden stake 21 with bolts.

[0026] Furthermore, the tensioning mechanism 5 includes a transverse plate 51, a longitudinal plate 52, a hook-shaped member 53, a tensioning bolt 54, a tensioning nut 56, and a clamping member 57. The front wall of the transverse plate 51 is fixed to the rear wall of the second wooden stake 21, and the outer end of the transverse plate 51 is fixed to the middle of the inner wall of the longitudinal plate 52. The front inner wall of the longitudinal plate 52 is connected to the outer wall of the second wooden stake 21. The hook-shaped member 53 includes a sliding plate 531, a transition plate 532, and an inclined plate 533. The front wall of the sliding plate 531 can slide in cooperation with the rear wall of the transverse plate 51, and the outer end of the sliding plate 531 is aligned with the rear wall of the transverse plate 51. The front end of the arc-shaped transition plate 532 is connected to the rear end of the transition plate 532, which is connected to the front end of the inclined plate 533. The rear end of the inclined plate 533 is inclined outward. The inner end of the tension bolt 54 is connected to the rear side of the outer wall of the inclined plate 533. The outer end of the tension bolt 54 passes through the rear side wall of the longitudinal plate 52 and is threaded to the tension nut 56. The inner end of the tension bolt 54 is perpendicular to the outer wall of the inclined plate 533. The clamping member 57 is used to clamp both ends of the geomembrane 4. The front wall of the clamping member 57 is fixedly connected to the rear wall of the sliding plate 531.

[0027] The working principle of the tensioning mechanism 5 is as follows: First, the two ends of the geomembrane 4 are clamped and fixed by the clamping member 57. Then, the tensioning nut 56 is tightened inward. During the tightening process of the tensioning nut 56, the tensioning bolt 54 can be moved outward, which in turn drives the inclined plate 533, the transition plate 532, the sliding plate 531 and the clamping member 57 to move outward in sequence, thereby achieving appropriate tensioning of the geomembrane.

[0028] Furthermore, the hook-shaped component 53 also includes a tensioning block 55, which is made of rubber. Its circumferential cross-section is annular and its axial cross-section is triangular. Its inner wall is parallel to the longitudinal plate 52, and the inner wall of the tensioning block 55 is fixed to the outer wall of the longitudinal plate 52. The outer wall of the tensioning block 55 is parallel to the inclined plate 533. The tensioning block 55 has a through hole in its axial direction for the tensioning bolt 54 to pass through. By using a tensioning block 55 made of rubber, wear between the tensioning nut 56 and the outer wall of the longitudinal plate 52 can be avoided.

[0029] Furthermore, the clamping member 57 includes a front clamping plate 571, a rear clamping plate 572, a clamping bolt 573, and a clamping nut 574. The front wall of the front clamping plate 571 is fixedly connected to the rear wall of the sliding plate 531. The rear clamping plate 572 has the same shape as the front clamping plate 571 and is arranged parallel to the rear side of the front clamping plate 571. The front end of the clamping bolt 573 passes through the middle of the rear clamping plate 572 and the rear wall of the front clamping plate 571. The middle fixed connection is provided, and the rear end of the clamping bolt 573 is connected to the clamping nut 574 by threads. When it is necessary to clamp the two ends of the geomembrane 4 by the clamping member 57, first loosen the clamping nut 574 to the rear side, insert the two ends of the geomembrane 4 between the front clamping plate 571 and the rear clamping plate 572, and then tighten the clamping nut 574 forward along the axial direction of the clamping bolt 573, so that the front clamping plate 571 and the rear clamping plate 572 clamp the two ends of the geomembrane 4.

[0030] Furthermore, a soil fill layer 6 is provided between the inner wall of the geomembrane 4 and the outer wall of the riverbank 3. Trees and shrubs can also be planted on top of the soil fill layer to form a third layer of water flow resistance and protection.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
