Description

Technical Field

[0001] This utility model relates to the field of gully erosion protection, specifically a biodegradable soil stabilization retaining wall module for gully erosion protection. Background Technology

[0002] Gullies are gullies formed by surface runoff erosion. They are widespread in the natural environment, especially in areas with severe soil erosion. The development of gullies can intensify, causing serious damage to land resources, the ecological environment, and agricultural production. Therefore, it is necessary to use biodegradable soil stabilization retaining walls to protect them, thereby effectively inhibiting the further development of gullies, reducing soil erosion, and protecting land resources and the ecological environment. When the soil stabilization retaining wall device is put into use, it may undergo large deformation due to poor inner support stability, which will affect the overall protective performance of the soil stabilization retaining wall. In addition, the retaining wall device cannot be quickly assembled during use, which increases the manpower and material costs and is relatively wasteful. Utility Model Content

[0003] The purpose of this invention is to provide a biodegradable soil stabilization retaining wall module for the protection of erosion gullies, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the following technical solution is provided: a biodegradable soil stabilization retaining wall module for erosion gully development protection, comprising geogrid one and geogrid two, with geogrid two located at one end of geogrid one, and both geogrid one and geogrid two being made of biodegradable material. Geogrid one and geogrid two form a mesh, and each geogrid one and geogrid two contains a cross-shaped eco-bag. Hooks are located at the center of the four sides of each geogrid one and geogrid two, and hanging holes are provided on the edges of the eco-bags corresponding to the hooks. The hooks are connected to the eco-bags through the hanging holes. Connecting blocks are provided at one end of each geogrid one and geogrid two. Each of the two geogrids is equipped with a connecting block 2 at the other end. Each connecting block 1 has a locking block at the middle of its end, and each connecting block 2 has a locking groove on one side. The locking blocks are engaged with the connecting block 2 through the corresponding locking grooves, so that the geogrid 1 and geogrid 2 are equipped with cross-shaped ecological bags, which can improve their stability. X-shaped support strips are set in the grid formed by their splicing, which can prevent the geogrid 1 and geogrid 2 from deforming due to soil compression, thereby enhancing the protective effect of the soil stabilization retaining wall. It can also be used to fix the geogrid 1 and geogrid 2 together, and the splicing between geogrids can be completed quickly, which greatly improves construction efficiency and saves time and manpower.

[0005] As a further technical solution of this utility model, both geogrid one and geogrid two are uniformly provided with transverse drainage channels one on their inner sides, and both geogrid one and geogrid two are uniformly provided with vertical drainage channels two on their inner sides, so that the drainage channels one and drainage channels two on the inner sides of geogrid one and geogrid two are staggered to form a grid, which can effectively guide and divert rainwater during the rainy season, prevent rainwater from accumulating in the geogrid, and thus reduce the risk of gully development.

[0006] As a further technical solution of this utility model, inclined support strips are provided between the outer sides of geogrid one and geogrid two, and the support strips are X-shaped, so that the two sets of support strips are X-shaped and supported in the grid formed by splicing geogrid one and geogrid two, which can prevent geogrid one and geogrid two from being deformed by force and enhance their stability.

[0007] As a further technical solution of this utility model, a T-shaped retaining strip is provided at the middle position of one side of the outer surface of geogrid 1 and geogrid 2, and a T-shaped groove 2 corresponding to the T-shaped retaining strip is provided at the middle position of the other side of the outer surface of geogrid 1 and geogrid 2. The T-shaped groove 2 is slidably connected to the corresponding T-shaped retaining strip, so that when geogrid 1 and geogrid 2 are spliced ​​up and down, the T-shaped retaining strip can slide into the T-shaped groove 2, and they can be spliced ​​up and down quickly.

[0008] As a further technical solution of this utility model, each of the connecting blocks on the outer side of the card block is provided with a moving groove, and each of the moving grooves is provided with a limiting piece. The limiting piece is slidably connected to the corresponding moving groove, so that after the card block is engaged, the limiting piece can move in the moving groove to limit the card block, which can prevent the card block from moving at will and make its engagement effect better.

[0009] As a further technical solution of this utility model, a T-shaped slide bar is provided at the middle position of the outer side of the limiting piece, and a T-shaped groove is provided in the connecting block 2 corresponding to the T-shaped slide bar. The T-shaped slide bar is slidably connected to the corresponding T-shaped groove, so that when the limiting piece moves, it can drive the T-shaped slide bar to slide in the T-shaped groove, which can make its movement more stable and smooth.

[0010] As a further technical solution of this utility model, both ends of the support strip are provided with sliders, and the outer surfaces of the geogrid 1 and geogrid 2 corresponding to the sliders are provided with grooves. The sliders are slidably connected to the corresponding grooves, so that when the support strip is inserted into the grid, the sliders at both ends can be driven to slide into the grooves, and the support strip can be installed quickly.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting cross-shaped ecological bags inside geogrid one and geogrid two, a stable overall structure can be formed. After the geogrids are spliced ​​together, two sets of inclined support strips are set in the grid to form an X shape, which can effectively disperse soil pressure and prevent geogrid one and geogrid two from deforming due to soil compression, thereby enhancing the protective effect of the soil stabilization retaining wall. 2. By interlocking and fixing the horizontal geogrid 1 and geogrid 2, and connecting the upper and lower geogrids, the splicing of geogrids can be completed quickly, which greatly improves construction efficiency and saves time and manpower.

[0014] Please see Figures 1-5This utility model provides an embodiment of a biodegradable soil stabilization retaining wall module for erosion gully development protection, including geogrid 1 and geogrid 2. One end of geogrid 1 is provided with geogrid 2, and both geogrid 1 and geogrid 2 are made of biodegradable materials. Geogrid 1 and geogrid 2 form a mesh, and both geogrid 1 and geogrid 2 are provided with cross-shaped ecological bags 3. Hooks 6 are provided in the middle of the four sides of geogrid 1 and geogrid 2, and the edges of the ecological bags 3 corresponding to the hooks 6 are provided with hanging holes 17. The hooks 6 are all connected to the ecological bags 3 through the hanging holes 17. The outer sides of geogrid 1 and geogrid 2 are provided with inclined support strips 7, and the support strips 7 are X-shaped. Both ends of the support strips 7 are provided with sliders 13, and the outer surfaces of geogrid 1 and geogrid 2 corresponding to the sliders 13 are provided with grooves 8, and the sliders 13 are all slidably connected to the corresponding grooves 8. Specifically, such as Figure 1 , Figure 2 and Figure 5 As shown, geogrid 1 and geogrid 2 are spliced ​​together after maintaining a certain distance. After splicing, the cross-shaped eco-bag 3 is placed inside geogrid 1 and geogrid 2. The eco-bag 3 is securely hung inside geogrid 1 and geogrid 2 by using the hooks 6 on the inside of geogrid 1 and geogrid 2 and the hanging holes 17 on the eco-bag 3, preventing displacement of the eco-bag 3 and forming a stable overall structure between geogrid 1 and geogrid 2, thus enhancing the protective effect of the soil stabilization retaining wall. Then, the support strips 7 are placed at both ends within the grid where the two sets of geogrid 1 and geogrid 2 are spliced ​​together. The slider 13 is aligned with the groove 8 on the outer surface of geogrid 1 and geogrid 2, so that the slider 13 moves downward along the groove 8. This allows the two sets of support bars 7 to be supported in the grid in an X shape. The X-shaped support bars 7 enhance the stability of the entire soil stabilization retaining wall module and effectively disperse soil pressure, preventing geogrid 1 and geogrid 2 from deforming due to soil compression. When the device is put into use, soil or filler can be filled into the grid, geogrid 1 and geogrid 2. The device can also be naturally degraded after a period of use, without causing long-term pollution to the environment, which is in line with the concept of green environmental protection. One end of geogrid 1 and geogrid 2 is provided with a connecting block 4, and the other end of geogrid 1 and geogrid 2 is provided with a connecting block 5. A locking block 9 is provided in the middle of one end of the connecting block 14, and a locking groove 15 is provided on one side of the connecting block 25 corresponding to the locking block 9. The locking block 9 is engaged with the connecting block 25 through the corresponding locking groove 15. A moving groove 10 is provided in the connecting block 25 outside the locking block 9, and a limiting piece 16 is provided in the moving groove 10. The limiting piece 16 is slidably connected to the corresponding moving groove 10. Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the locking block 9 of the connecting block 4 at one end of geogrid 1 is engaged in the slot 15 of the connecting block 5 at one end of geogrid 2. After the engagement is completed, the limiting piece 16 can be pushed down to move downward in the moving groove 10 to limit the locking block 9 and prevent it from moving. This allows workers to quickly complete the splicing between geogrids during the installation of geogrid 1 and geogrid 2, which greatly improves construction efficiency and saves time and labor costs. Both geogrid 1 and geogrid 2 have horizontal drainage channels 14 evenly distributed on their inner sides, and both geogrid 1 and geogrid 2 have vertical drainage channels 19 evenly distributed on their inner sides. Specifically, such as Figure 2 and Figure 5 As shown, the drainage channels 14 and 29 on the inner sides of geogrid 1 and geogrid 2 are interwoven to form a grid structure. During rainfall, rainwater can be quickly discharged along the drainage channels 14 and 29 to prevent rainwater from accumulating inside the geogrid, effectively preventing erosion of the geogrid by water accumulation and enhancing the drainage effect of the geogrid. T-shaped clips 20 are provided at the middle position of one side of the outer surface of geogrid 1 and geogrid 2, and T-shaped grooves 22 corresponding to the T-shaped clips 20 are provided at the middle position of the other side of the outer surface of geogrid 1 and geogrid 2, and the T-shaped grooves 22 are slidably connected to the corresponding T-shaped clips 20. Specifically, such as Figure 1 and Figure 2 As shown, when geogrid 1 and geogrid 2 are spliced ​​together, the T-shaped clip 20 on one side of geogrid 1 can slide into the T-shaped groove 2 12 of another set of geogrid 1, which can quickly splice the geogrids together and improve the working speed. T-shaped slide bars 18 are provided at the middle position of the outer side of the limiting piece 16, and T-shaped grooves 11 are provided in the connecting block 2 5 corresponding to the T-shaped slide bars 18, and the T-shaped slide bars 18 are slidably connected to the corresponding T-shaped grooves 11. Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, when the limiting piece 16 moves, it can drive the T-shaped slide bar 18 to move within the T-shaped groove 11, which can make the movement of the limiting piece 16 more stable and smooth.

[0015] The working principle of this utility model is as follows: In use, the locking block 9 of the connecting block 4 at one end of geogrid 1 engages with the locking groove 15 of the connecting block 5 at one end of geogrid 2. After engagement, the limiting piece 16 can be pushed downwards to move downwards within the moving groove 10, thus limiting the locking block 9 and preventing it from moving. As the limiting piece 16 moves, it can drive the T-shaped sliding strip 18 to move within the T-shaped groove 11, making the movement of the limiting piece 16 more stable and smooth. After the horizontal geogrid splicing is completed, the T-shaped locking strip 20 on one side of geogrid 1 can slide and engage with the other geogrid. Within the T-shaped groove 12 of a set of geogrid 1, geogrids can be quickly spliced ​​together, allowing workers to rapidly complete the splicing between geogrids, greatly improving construction efficiency and saving time and labor costs. After splicing, a cross-shaped eco-bag 3 can be placed inside geogrid 1 and geogrid 2. Using the hooks 6 on the inner sides of geogrid 1 and geogrid 2 and the hanging holes 17 on the eco-bag 3, the eco-bag 3 is securely hung inside geogrid 1 and geogrid 2, preventing displacement of the eco-bag 3 and ensuring the geogrid 1... Together with geogrid 2, they form a stable overall structure, enhancing the protective effect of the soil stabilization retaining wall. Then, within the grid where the two sets of geogrids 1 and 2 are spliced ​​vertically, the sliders 13 at both ends of the support strip 7 are aligned with the grooves 8 on the outer surfaces of geogrids 1 and 2, allowing the sliders 13 to move downwards along the grooves 8. This allows the two sets of support strips 7 to be supported in an X-shape within the grid, enhancing the stability of the entire soil stabilization retaining wall module and effectively dispersing soil pressure, preventing geogrids 1 and 2 from deforming due to soil compression. When the device is put into operation... When in use, soil or filler can be filled into the grid, geogrid 1 and geogrid 2. The device can be naturally degraded after a period of use, without causing long-term pollution to the environment, which is in line with the concept of green environmental protection. During the rainy season, the drainage channels 14 and 29 on the inner side of geogrid 1 and geogrid 2 can be interwoven to form a grid structure, and rainwater can be quickly discharged along the drainage channels 14 and 29 to prevent rainwater from accumulating in the geogrid, effectively preventing erosion of the geogrid due to water accumulation and enhancing the drainage effect of the geogrid.
