AI Technical Summary
In existing green prefabricated soil nailing wall layers, the connection between the reinforcement layer and the skin layer is mostly planar bonding, which leads to increased gaps between layers, affects load transfer efficiency, and easily causes the protective structure to fail when the slope soil deforms.
The honeycomb-shaped reinforcing layer is used to create a three-dimensional connection by interlocking the protective material layer and the skin layer, reducing the porosity, improving the interlayer bonding force, and ensuring that the slope remains tightly attached during settlement.
The three-dimensional connection structure reduces interlayer slippage, improves durability and load transfer efficiency, and enhances slope protection.

[0024] Example 1
[0025] like Figures 1-3 As shown:
[0026] A green prefabricated soil nailing wall slope protection surface layer includes a skin layer 1, a protective material layer 2, a honeycomb reinforcement layer 3, and a performance material layer 4, wherein the honeycomb reinforcement layer 3 is provided with protrusions 5 that penetrate the protective material layer 2 and are embedded and connected to the skin layer 1.
[0027] A groove 11 is provided on the skin layer 1 to fit into the end of the protrusion 5. The protrusion 5 and the groove 11 are thermally bonded together to form a mechanical lock.
[0028] Skin layer 1 is made of high-density polyethylene, polyvinyl chloride and other flexible polymer materials.
[0029] The protective material layer 2 is made of fibers stitched together from polymer materials. The protective material layer 2 can be made of glass fiber, polyester fiber or polypropylene fiber.
[0030] The protrusion 5 is thermally bonded to the protective material layer 2 to form a mechanical fit.
[0031] The honeycomb-shaped reinforcing layer 3 has multiple hexagonal honeycomb holes 31, and protrusions 5 are provided at the connection of adjacent honeycomb holes 31. The length of the protrusions 5 is 1-3mm.
[0032] The tensile strength of the honeycomb reinforcing layer 3 is 15-40 kN / m, and the side length of the honeycomb holes 31 is 8-12 mm.
[0033] The honeycomb reinforcing layer 3 is made of polypropylene, polyethylene or carbon fiber reinforced composite material.
[0034] The honeycomb reinforcing layer 3 is formed into hexagonal honeycomb holes 31 by die stamping, and the corners of the honeycomb holes 31 are hot-pressed to form protrusions 5.
[0035] The performance material layer 4 is made of high molecular polymer materials such as epoxy resin, polyurethane or acrylate polymer.
[0036] During construction, the protective surface layer is fixed by anchor nails. Most of the soil on the slope is blocked by the skin layer 1, while a small portion penetrates into the fibers of the protective material layer 2 and the honeycomb pores 31 of the honeycomb reinforcement layer 3. The protrusions 5 and the protective material layer 2 effectively prevent the generation of interlayer voids and improve the effect of preventing soil particle loss.
[0037] On the outer performance material layer of soil nailing wall slope protection, functional layers can be added according to the characteristics of the site environment to adapt to specific needs such as climate, topography, and ecology, thereby improving the adaptability and durability of the protection system. For example, in areas with sensitive natural environments or slopes requiring greening, vegetation blankets or vegetated concrete can be installed on the performance material layer to achieve ecological restoration of the slope, reduce soil erosion, and improve the landscape; in areas with heavy rainfall and strong water erosion, a combination of polypropylene woven fabric or high-density polyethylene geomembrane and pebble cushion layer can be installed on the performance material layer to resist the direct erosion of the protection surface by rainwater and surface runoff, preventing the loss of surface materials or structural damage; in forest areas, factory areas, and other areas with fire prevention requirements, a combination of intumescent fire-retardant coating or fiberglass cloth and flame-retardant resin composite layer can be installed on the performance material layer to block heat transfer, form a fire barrier, and balance strength and fire resistance; in areas near roads, factories, and other areas requiring safety warnings, a reflective coating layer can be installed on the performance material layer to enhance nighttime visibility.
[0038] This invention utilizes the protrusions of the honeycomb-shaped reinforcing layer to interlock and connect the protective material layer and the skin layer, forming a three-dimensional connection. This reduces porosity, minimizes interlayer slippage, and enhances interlayer bonding strength, ensuring a tight fit during slope settlement and improving durability. The existing square reinforcing layer is replaced with a honeycomb grid, leveraging the geometric advantages of hexagons to reduce voids and increase contact area. This significantly improves deformation resistance and soil particle loss prevention.
[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
