Description

Technical Field

[0001] This utility model relates to the field of slope protection technology, and more specifically, to a prefabricated green retaining wall structure. Background Technology

[0002] Prefabricated green retaining wall structures in slope protection organically integrate engineering protection and ecological concepts, possessing diverse and practical functions. From an engineering protection perspective, the stable connections between prefabricated components effectively resist lateral pressure from the slope soil, significantly reducing the risk of slope collapse. A rationally designed drainage system promptly removes surface water, preventing soil softening caused by water accumulation and greatly enhancing slope stability. From an ecological and environmental perspective, the structure features dedicated planting spaces, promoting natural vegetation growth. This not only stabilizes the slope but also purifies the air, regulates the local microclimate, and contributes to the restoration and balance of the ecosystem. Furthermore, the prefabricated green retaining walls offer rich shapes and diverse vegetation options, blending naturally with the surrounding landscape and significantly enhancing its aesthetic appeal and harmony, beautifying the surrounding environment. In addition, the standardized production and on-site assembly of prefabricated components greatly shortens the construction cycle, reduces environmental impact, and facilitates later maintenance, minimizing resource consumption and waste.

[0003] Chinese invention patent application number 202011633613.0 discloses a prefabricated green ecological retaining wall. The retaining wall mainly consists of a retaining wall foundation, a prefabricated wall body, and a capping beam. The prefabricated wall body is assembled from multiple wall body units, each containing a wall panel. A planting board is integrally formed on the front side of the wall panel, creating a planting area between the two and providing space for vegetation growth.

[0004] In the process of landscape design, the plant configuration in the retaining wall planting area plays a crucial role in shaping the overall landscape effect. When the landscape plan is adjusted or aesthetic standards change, it is often necessary to replace the vegetation in the planting area.

[0005] Currently, manual removal is commonly used when replacing vegetation. However, the planting space along retaining walls is relatively narrow, requiring construction workers to manually clear everything, whether transplanting plants or removing soil. This method is not only labor-intensive but also extremely inefficient, severely impacting the progress of landscape renovation and increasing both labor and time costs. Utility Model Content

[0007] The embodiments of this utility model are implemented as follows:

[0008] This application provides a prefabricated green retaining wall structure, including a retaining wall foundation, a prefabricated wall body, and a retaining wall capping beam. The prefabricated wall body includes multiple interconnected wall body units. Each of the wall body units includes: a planar wall body panel; two concave wall body panels located at opposite ends of the planar wall body panel and symmetrically distributed with the center of the planar wall body panel as the center of symmetry; wherein the openings of the two concave wall body panels face opposite directions, and together with the planar wall body panel, they form a planting space; and a splicing assembly, including a planting board and a positioning part. The positioning part is disposed on the planar wall body panel within the planting space, and the positioning part is provided with a docking groove. The planting board is inserted into the planting space and simultaneously inserted into the docking groove. The positioning part is provided with a locking structure for locking the planting board within the docking groove.

[0009] Furthermore, based on the aforementioned scheme, the planting board is provided with inserts, and the planting space is provided with slots that are adapted to the inserts.

[0010] Furthermore, based on the aforementioned scheme, the locking structure is a bolt.

[0011] Furthermore, based on the aforementioned scheme, multiple slots are provided on the top side of the planting board;

[0012] The planting board has a nutrient solution tank on its bottom side, and the nutrient solution tank is equipped with a fiber tube. The end of the fiber tube away from the nutrient solution tank extends into the groove.

[0013] Furthermore, based on the aforementioned scheme, the planar wall panel and the two concave wall panels constitute an integrally formed structure.

[0014] Furthermore, based on the aforementioned scheme, the number of positioning units is two.

[0015] Furthermore, based on the aforementioned scheme, drainage windows are provided on the planar wall panels within the planting space, and the drainage windows are located above the planting panels.

[0016] Furthermore, based on the aforementioned scheme, tenons are provided on the top side of the planar wall panel and the top side of the two concave wall panels, and mortises are provided on the bottom side of the planar wall panel and the bottom side of the two concave wall panels.

[0019] In practical applications, this application constructs a prefabricated green retaining wall structure through retaining wall foundations, retaining wall capping beams, and multiple wall units, achieving effective slope support. Soil is filled into the planting space above the planting board to complete vegetation planting. When landscape planning changes and vegetation replacement is required, the locking structure is operated to disassemble the planting board, which then becomes movable. The planting board can then be simply pulled out of the planting space. After the planting board is removed, the soil and vegetation lose their primary support, relying only on weak forces between themselves and the planar or concave wall panels to maintain their position, resulting in a significant decrease in adhesion. Simultaneously, since the planting board no longer acts as an obstruction, workers can more easily remove the soil and vegetation from the planting area. Compared to traditional green retaining walls, this design greatly reduces the labor intensity of soil and vegetation removal for construction workers, significantly improves work efficiency, reduces labor and time costs, and provides strong support for the smooth progress of landscape renovation work, demonstrating significant practicality.

Detailed Implementation

[0030] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0031] Example

[0032] Please refer to Figures 1-8 This application provides a prefabricated green retaining wall structure, including a retaining wall foundation 1, a prefabricated wall body, and a retaining wall capping beam 2. The prefabricated wall body includes multiple interconnected wall body units 3. Each of the wall body units 3 includes: a planar wall panel 4; two concave wall panels 5, which are located at both ends of the planar wall panel 4 and are symmetrically distributed with the middle of the planar wall panel 4 as the center of symmetry; wherein the openings of the two concave wall panels 5 face opposite directions, and together with the planar wall panel 4, they form a planting space 6; and a splicing assembly, including a planting plate 8 and a positioning part 12. The positioning part 12 is disposed on the planar wall panel 4 within the planting space 6, and the positioning part 12 is provided with a docking groove 1201. The planting plate 8 is inserted into the planting space 6 and simultaneously inserted into the docking groove 1201; wherein the positioning part 12 is provided with a locking structure for locking the planting plate 8 within the docking groove 1201.

[0033] In practical applications, this application constructs a prefabricated green retaining wall structure using retaining wall foundation 1, retaining wall capping beam 2, and multiple wall unit bodies 3, achieving effective slope support. Soil is filled into the planting space 6 above the planting board 8 to complete vegetation planting. When landscape planning changes and vegetation needs to be replaced, the locking structure is operated to disassemble it, and the planting board 8 becomes movable. At this point, the planting board 8 can simply be pulled out of the planting space 6. After the planting board 8 is removed, the soil and vegetation lose their original primary support, relying only on the weak force between themselves and the planar wall panel 4 and concave wall panel 5 to maintain their position, resulting in a significant decrease in adhesion. Simultaneously, since the planting board 8 no longer forms an obstruction, workers can more easily remove the soil and vegetation from the planting area. Compared to traditional green retaining walls, this design greatly reduces the labor intensity of construction workers removing soil and vegetation, significantly improves work efficiency, reduces labor and time costs, and provides strong support for the smooth progress of landscape renovation work, demonstrating significant practicality.

[0034] Optionally, the planting board 8 can be designed as an inclined structure, that is, the height of the outer side of the planting board 8 is higher than the height of the inner side of the planting board 8, so that the planting board 8 is inclined towards the planting space 6, which has the advantage of preventing soil erosion.

[0035] In a preferred embodiment, the planting plate 8 is provided with a plug 15, and the planting space 6 is provided with a slot 14 adapted to the plug 15.

[0036] In the above embodiments, during installation, the insert 15 precisely aligns with the slot 14, enabling rapid positioning and installation of the planting board 8. This significantly shortens construction time, reduces construction difficulty, and the fitting structure ensures a more stable connection between the planting board 8 and the planting space 6. When vegetation needs to be replaced due to changes in landscape planning, the planting board 8 can be easily removed by simply pulling out the insert 15. This facilitates cleaning of the planting area, effectively reduces labor intensity, and improves maintenance efficiency.

[0037] Optionally, slots 14 are provided on both sides of the planting space 6 in the lateral direction, and inserts 15 are provided on both sides of the planting board 8 in the lateral direction. The double-sided insertion structure of the planting board 8 forms a double constraint. When the planting board 8 is subjected to external forces such as pulling or vibration, the slots 14 and inserts 15 on both sides are tightly engaged, which helps to disperse the external force and significantly enhances the stability of the connection between the planting board 8 and the planting space 6.

[0038] As a preferred implementation, the locking structure described above is a bolt.

[0039] In the above embodiments, the bolts, thanks to their simple operation, can be quickly tightened using only conventional tools such as wrenches, firmly locking the planting board 8 into the mating groove 1201, significantly shortening installation time and reducing the professional skills required of construction personnel. During use, the bolted connection exhibits excellent fastening performance. Even if the retaining wall is subjected to severe weather conditions such as heavy rainfall, strong winds, or displacement due to geological activity, the strong fastening force provided by the bolts effectively prevents the planting board 8 from loosening or falling off, ensuring the stability of the retaining wall structure.

[0040] As a preferred embodiment, the top side of the planting board 8 is provided with a plurality of slots 9;

[0041] The planting board 8 is provided with a nutrient solution tank 13 on its bottom side. The nutrient solution tank 13 is provided with a fiber tube 16. One end of the fiber tube 16 away from the nutrient solution tank 13 extends into the groove 9.

[0042] In the above embodiment, the nutrients in the nutrient solution storage tank 13 are slowly transported to the trough 9 through the fiber tube 16 by capillary action. The trough 9 serves as a carrier for the extension of the fiber tube 16 and allows the plant roots to fully contact the seeping nutrient solution and absorb the required nutrients.

[0043] Optionally, the nutrient solution tank 13 is provided with an opening, and the opening is detachably fitted with a sealing plug, through which the nutrient solution can be added or replaced.

[0044] As a preferred embodiment, the planar wall panel 4 and the two concave wall panels 5 constitute an integrally formed structure.

[0045] In the above embodiments, the planar wall panel 4 and the two concave wall panels 5 adopt an integral molding structure, which not only greatly enhances the structural strength and stability of the wall unit 3 and reduces the risk of water seepage caused by splicing gaps, but also simplifies the production process, reduces the assembly process, reduces construction costs, and significantly improves the overall quality and installation efficiency of the prefabricated green retaining wall.

[0046] In a preferred embodiment, the number of the positioning parts 12 is two.

[0047] In the above embodiment, the number of positioning parts 12 is set to two, which can accurately position the planting board 8 from different positions, effectively avoid the offset or shaking of the planting board 8 during installation, greatly improve the stability of the connection between the planting board 8 and the planting space 6, and ensure that the overall structure of the retaining wall maintains a reliable state during long-term use.

[0048] In a preferred embodiment, a drainage window 7 is provided on the planar wall panel 4 within the planting space 6, and the drainage window 7 is located above the planting panel 8.

[0049] In the above embodiment, the design of the drainage window 7 serves two purposes. First, it allows accumulated water to drain away promptly, preventing the soil inside the retaining wall from softening due to water accumulation and maintaining soil stability, thus ensuring the retaining wall's support effect on the slope. Second, the drainage window 7 creates a channel for the vegetation in the planting space 6, allowing its roots to penetrate and connect with the soil inside the retaining wall. This not only provides sufficient nutrients for plant growth but also further reinforces the soil with the help of plant roots, enhancing the overall slope protection effectiveness of the retaining wall.

[0050] In a preferred embodiment, tenons 10 are provided on the top side of the planar wall panel 4 and the top side of the two concave wall panels 5, and mortises 11 are provided on the bottom side of the planar wall panel 4 and the bottom side of the two concave wall panels 5.

[0051] In the above embodiment, when the two wall units 3 are vertically joined, the tenon 10 and the mortise 11 are aligned, which not only greatly enhances the stability and firmness of the connection between the wall units 3, effectively resists external forces, and reduces the risk of structural deformation and loosening, but also makes the splicing process more convenient and efficient, and improves the construction efficiency of the prefabricated green retaining wall.

[0052] As a preferred embodiment, it also includes retaining wall ribs for connecting the retaining wall foundation 1 and the retaining wall capping beam 2.

[0053] In the above embodiments, the retaining wall ribs can not only enhance the overall vertical bearing capacity of the retaining wall and effectively disperse and transmit the pressure from the superstructure, but also enhance the overturning and sliding performance of the retaining wall through the synergistic force-bearing mechanism, greatly improve the stability of the retaining wall under complex geological conditions, and ensure the slope protection effect.
