Description

Technical Field

[0001] This utility model relates to the field of retaining wall technology, specifically to an ecological gabion retaining wall. Background Technology

[0002] In river regulation projects, traditional revetment or slope protection materials such as dry-laid stone and precast concrete blocks, due to their poor permeability, can disrupt the normal cycle of the river's natural ecosystem, contradicting the concept of ecological river management. Gabion retaining walls, as a new type of retaining structure, are composed of double-twisted metal mesh filled with boulders or pebbles. They can adapt to various soil properties and integrate well with them, effectively adapting to foundation deformation without weakening the overall structure, and are less prone to breakage. They also possess many other advantages: erosion resistance, self-permeability, strong integrity, and the ability to withstand wind and waves. Their porous structure also facilitates biological habitats, meeting the needs of vegetation restoration, ecological restoration, and earthquake disaster reduction projects. Furthermore, they are widely used in protection scenarios for various projects such as rivers, lakes, seas, mines, water conservancy, waterways, railways, and highways, combining erosion resistance with drainage and consolidation functions.

[0003] With the continuous upgrading of steel wire anti-corrosion technology, gabion stone cages are increasingly used in the construction of ecological river channels. However, from the actual construction situation, there are still some problems. Due to the easy deformation of gabion stone cages, their irregular shape, large gaps between stone cages, and insufficient binding between stone cages, the stability of gabion stone cage retaining walls is not strong enough, and they are prone to collapse when the water flow is too large. Utility Model Content

[0004] To address the aforementioned problems in the existing technology, this utility model provides an ecological gabion retaining wall, which solves the problem of insufficient stability of existing gabion retaining walls.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An ecological gabion retaining wall is provided, including a gabion retaining wall body. The gabion retaining wall body has an L-shaped structure and includes vertical walls and horizontal walls. A grid beam is provided on the end face of the vertical wall near the horizontal wall. The grid beam includes two longitudinal beams. The top and bottom of the two longitudinal beams are fixedly connected to the upper horizontal beam and the lower horizontal beam, respectively. The upper horizontal beam and the lower horizontal beam are fixedly connected to multiple inclined anchors and transverse anchors that penetrate the vertical wall. The penetrating end of each inclined anchor and transverse anchor is used for fixed connection with the foundation.

[0006] The beneficial effects of this solution are as follows: by adopting an L-shaped retaining wall main body, a self-weight retaining system is formed, which improves the anti-sliding and anti-overturning stability of the retaining wall. In addition, the combination of grid beams and inclined anchor rods and transverse anchor rods firmly anchors the retaining wall to the foundation. Compared with the existing technology of scattered gabion stone cages, it enhances the integrity and durability, and solves the problem of weak stability of gabion stone cage retaining walls in the existing technology.

[0007] Furthermore, the main body of the gabion retaining wall comprises multiple interconnected gabion frames, each filled with stones. The modular design of the gabion retaining wall facilitates transportation, installation, and maintenance. The stones inside each gabion frame provide sufficient self-weight and strength, enabling the retaining wall to adapt to foundation deformation. The modular design also allows for flexible adjustment of the retaining wall dimensions to meet different engineering needs.

[0008] Furthermore, each gabion frame is a cuboid structure, and adjacent gabion frames are fixedly connected by spiral-wound steel wire and cross-shaped clips. The cuboid structure ensures the regularity of the gabion frame shape, reduces gaps during stacking, and improves structural tightness. The spiral-wound steel wire and cross-shaped clips provide a robust mechanical connection, preventing relative displacement or loosening of adjacent frames under load.

[0009] Furthermore, the frame of each gabion is made of double-twisted wire mesh. Double-twisted wire mesh has high strength and flexibility, which can adapt to foundation settlement or deformation and prevent mesh breakage; its porous structure is conducive to water permeability and vegetation growth, which is in line with the concept of ecological river management. The double-twisted design also makes it easy for inclined and horizontal anchors to pass through its mesh and be fixed to the foundation, improving the durability and eco-friendliness of the retaining wall.

[0010] Furthermore, a filter layer is installed on the end face of the vertical wall away from the horizontal wall. The filter layer can effectively prevent the loss of fine particles from the soil behind the retaining wall, reduce soil erosion, and at the same time allow water to flow through, reducing hydrostatic pressure.

[0011] Furthermore, the filter layer includes a gravel layer with a thickness of 15–25 cm. The gravel layer has good permeability and anti-clogging ability, effectively intercepting fine soil particles, ensuring smooth drainage, and further enhancing the stability and ease of maintenance of the retaining wall.

[0012] Furthermore, multiple drainage pipes are installed at the bottom of the extended section of the transverse wall. These drainage pipes can promptly remove accumulated water from inside the gabion retaining wall, reducing water pressure. Furthermore, each cross-shaped clip, as well as the surface of each inclined and transverse anchor bolt, is coated with an anti-rust layer. This anti-rust layer, such as galvanizing or coating, protects the metal components from corrosion, especially in riverbeds or humid environments, preventing a decrease in connection strength due to rust. This ensures the long-term reliability of the anchoring system and connection points, maintaining the stability and safety of the overall structure. Attached Figure Description

Detailed Implementation

[0014] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0015] This embodiment provides an ecological gabion retaining wall to solve the problem of weak stability of existing gabion retaining walls, which includes a gabion retaining wall body 100.

[0016] refer to Figure 1 and Figure 2The main body 100 of the gabion retaining wall is L-shaped, including vertical walls 11 and horizontal walls 12. Both vertical walls 11 and horizontal walls 12 consist of multiple interconnected gabion frames 500, each filled with stones. The main body of the gabion retaining wall is composed of multiple interconnected gabion frames 500. The modular design facilitates transportation, installation, and maintenance. The stones inside each gabion frame 500 provide sufficient self-weight and strength, enabling the retaining wall to adapt to foundation deformation. The modular design also allows for flexible adjustment of the retaining wall dimensions to meet different engineering needs.

[0017] A grid beam 200 is installed on the end face of the vertical wall 11 near the horizontal wall 12. The grid beam 200 is welded from structural steel. Specifically, the grid beam 200 includes two longitudinal beams, the top and bottom of which are welded to the upper horizontal beam 21 and lower horizontal beam 22, respectively. The upper horizontal beam 21 and lower horizontal beam 22 are fixedly connected to multiple inclined anchor rods 300 and transverse anchor rods 400, each penetrating the vertical wall 11. Specifically, the upper horizontal beam 21 and lower horizontal beam 22 are respectively provided with holes for the inclined anchor rods 300 and transverse anchor rods 400. The multiple inclined anchor rods 300 and transverse anchor rods 400 pass through the upper horizontal beam 21 and lower horizontal beam 22 and are anchored to the foundation behind the vertical wall. The cooperation of the grid beam 200 with the inclined anchor rods 300 and transverse anchor rods 400 firmly anchors the retaining wall to the foundation, enhancing the integrity and durability compared to the existing loosely assembled gabion 500 technology.

[0018] refer to Figure 5 A filter layer 13 is provided on the end face of the vertical wall 11 away from the horizontal wall 12. The filter layer 13 can be a gravel layer with a thickness of 15-25cm. The gravel layer has good permeability and anti-clogging ability, which can effectively intercept fine soil particles, ensure smooth drainage, and enhance the stability and maintenance convenience of the retaining wall.

[0019] Multiple drainage pipes 121 are installed at the bottom of the extension section of the transverse wall 12. The drainage pipes 121 can promptly remove accumulated water inside the main body 100 of the gabion retaining wall and reduce water pressure.

[0020] In this embodiment, reference Figure 3 Each gabion frame 500 is a cuboid structure, and the frame surface of each gabion frame 500 is a double-twisted wire mesh. The double-twisted wire mesh has high strength and flexibility, which can adapt to foundation settlement or deformation and avoid mesh breakage; its porous structure is conducive to water permeability and vegetation growth, which is in line with the concept of ecological river management. The double-twisted design also makes it easy for inclined anchor bolts 300 and horizontal anchor bolts 400 to pass through its mesh and be fixed to the foundation, improving the durability and eco-friendliness of the retaining wall.

[0021] refer to Figure 1 , Figure 3 and Figure 4Adjacent gabion cages 500 are fixedly connected by spiral-wound steel wire 51 and cross-shaped clips 52. This design limits the gabion cages 500 to a rectangular structure, ensuring their regular shape, reducing gaps during stacking, and improving structural tightness. The spiral-wound steel wire 51 can be galvanized steel wire. The spiral-wound steel wire 51 and the cross-shaped clips 52 provide a strong mechanical connection, preventing relative displacement or loosening of adjacent cages under load.

[0022] The specific connection method of the spiral-wound steel wire 51 and the cross-shaped clip 52 is as follows: The spiral-wound steel wire 51 needs to tightly wrap and connect each gabion frame 500 on the edge of the gabion retaining wall body, and together with the cross-shaped clip 52, fix the gabion frame to ensure its stability. First, use the cross-shaped clip 52 to fix the gabion frame 500, and then use the spiral-wound steel wire 51 to connect and fix only the adjacent joints of the outermost gabion frame 500, so as to make the installation more convenient and not affect the overall stability of the gabion retaining wall body.

[0023] As a further embodiment, to ensure the long-term reliability of the anchoring system and connection points, and to maintain the stability and safety of the overall structure, each cross-shaped clip 52, as well as the surface of each inclined anchor bolt 300 and transverse anchor bolt 400, is provided with an anti-rust layer. The anti-rust layer, such as galvanizing or coating, protects the metal components from corrosion, especially in riverbeds or humid environments, preventing a decrease in connection strength due to rust. As another embodiment, the cross-shaped clip 52 can also adopt a sandwich structure, first applying a waterproof coating, such as polyurethane or fluoride, to the surface, and then attaching a layer of fabric or leather to increase its waterproof and anti-rust properties.

[0024] In summary, the installation method of this solution is as follows: refer to Figure 5 During use, after the workers excavate the foundation pit, they lay the vertical walls 11 of the gabion retaining wall main body 100 at the required locations. Stones are placed in each gabion frame 500; the stones must be clean, hard, and free from weathering. Basalt and pebbles can meet these requirements. Several gabion frames 500 are arranged neatly, and adjacent gabion frames 500 are tightly connected and fixed using spiral-wound steel wire 51 and cross-shaped clips 52. A layer of gabion frames 500 is laid at the bottom front side of the retaining wall as a horizontal wall 12, and the horizontal wall 12 is buried in the soil to make the structure more stable. The drainage pipe 121 is installed at the bottom front row of gabion frames of the transverse wall 12. It is inserted into the soil and fixed at the lowest edge of the outer gabion frame. Water can naturally sink to the bottom through the gabion frame and be discharged through the drainage channel pipe. Then, the grid beam 200 is welded and assembled with the inclined anchor 300 and the transverse anchor 400. The inclined anchor 300 and the transverse anchor 400 are inserted through the vertical wall 11 and inserted into the foundation.

[0025] Although specific embodiments of the utility model have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this solution. Various modifications and variations that can be made by those skilled in the art without inventive effort within the scope described in the claims still fall within the scope of protection of this solution.
