Description

Technical Field

[0001] This utility model belongs to the field of slope protection netting technology, and in particular relates to a multi-layer combined slope protection netting. Background Technology

[0002] Slope protection nets are protective devices used in landslides on highways and railways. Various flexible nets, mainly steel wire rope nets, are used to cover and wrap the slopes or rocks that need protection, in order to limit the weathering and erosion or damage of the slope rocks and soil and prevent rockfalls (reinforcement function), or to control the movement of falling rocks within a certain range (containment function). Usually, steel wire rope nets are fixed to the slope surface of the mountain using anchor rods.

[0003] A multi-layered composite slope protection net is disclosed in utility model patent CN217840043U, belonging to the field of slope protection net technology. This multi-layered composite slope protection net includes an inner three-dimensional net, a middle layer of diamond-shaped net providing support for the three-dimensional net, and an outer flexible slope protection net; the three layers are fixed to the mountain surface using anchor bolts. This product has a three-layer structure. The innermost layer is a three-dimensional net with a high density and dense mesh, effectively preventing small stones from falling, while also being aesthetically pleasing and effectively preventing soil erosion. The middle layer is a diamond-shaped net, serving as the support and framework for the three-dimensional net. The outermost layer is a flexible slope protection net with a larger wire diameter, providing the main mechanical support and acting as the main load-bearing structure. Combining these three different nets together effectively prevents the falling of various small stones while maintaining good strength, resulting in a long service life and excellent performance.

[0004] Regarding the aforementioned related technologies, the inventor believes that the following defects exist:

[0005] 1. Slope construction can cause significant damage to the original landform and make ecological restoration difficult. These problems not only limit the sustainable development of the project, but also contradict the current goal of pursuing ecological civilization.

[0006] Therefore, it is necessary to provide a new multi-layered composite slope protection net to solve the above-mentioned technical problems. Utility Model Content

[0022] Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 This is a schematic diagram of the structure of the present invention. Figure 1 ; Figure 2 This is a schematic diagram of the structure of the present invention. Figure 2 ; Figure 3 This is a schematic diagram of the reinforcement mechanism of this utility model. The multi-layer combined slope protection net includes: a slope paving surface 100 set on the slope body 1, a nutrient soil layer 101 provided on the slope paving surface 100, and seeds evenly planted on the nutrient soil layer 101;

[0023] A reinforcement mechanism 2 is laid on the nutrient soil layer 101. The reinforcement mechanism 2 includes a coconut fiber blanket 3 and a three-dimensional soil stabilization mat 4. The coconut fiber blanket 3 is laid on the nutrient soil layer 101, and the three-dimensional soil stabilization mat 4 is laid on the coconut fiber blanket 3.

[0024] The reinforcement mechanism 2 also includes a three-dimensional net 5, which is laid on a three-dimensional soil stabilization mat 4. The coconut fiber blanket 3, the three-dimensional soil stabilization mat 4 and the three-dimensional net 5 are installed on the slope body 1 by multiple anchor rods 6.

[0025] The reinforcement mechanism 2 also includes a diamond mesh 7 and a flexible slope protection net 8. The diamond mesh 7 is laid on the three-dimensional mesh 5, and the flexible slope protection net 8 is laid on the diamond mesh 7.

[0026] The flexible slope protection net 8, diamond net 7, three-dimensional net 5, three-dimensional soil stabilizing net mat 4 and coconut fiber blanket 3 are installed on the slope body 1 through multiple anchor rods 9.

[0027] The coconut fiber blanket 3 is made of natural coconut fiber and has good biodegradability and environmental friendliness.

[0028] The three-dimensional soil stabilization mat 4 is a multi-layered plastic three-dimensional soil stabilization mat made of thermoplastic resin.

[0029] The working principle of the multi-layer combined slope protection net provided by this utility model is as follows:

[0030] The first step involves preparing the slope surface 100 on slope body 1 and filling it with a nutrient soil layer 101. Then, water is sprinkled and seeds are planted. Next, coconut fiber mat 3 and three-dimensional soil-stabilizing netting 4 are laid in sequence. The coconut fiber mat 3 has dense and appropriately sized mesh openings, allowing various grass seeds to easily penetrate and grow vigorously. The coconut fiber mat provides moisture retention, wind protection, and heat preservation for the early, middle, and late stages of plant growth, respectively. It also has good water retention and air permeability, keeping the soil moist and providing ideal conditions for seed germination and growth. As the coconut fiber mat degrades, its organic components provide nutrients for vegetation, promoting rapid vegetation coverage and root development, thereby enhancing the slope's resistance to erosion. The three-dimensional soil-stabilizing netting 4 has a three-dimensional structure similar to a loofah network, with a loose and flexible texture, providing 90% space for soil, gravel, and fine stones, promoting deep root development and forming a robust green protective layer.

[0031] The second step: The combination of three-dimensional net 5, anchor rod 1 6, diamond net 7, flexible slope protection net 8 and anchor rod 2 9 can not only reinforce the nutrient soil layer 101, seeds, coconut fiber blanket 3 and three-dimensional soil stabilizing net mat 4, but also prevent various small stones from falling. In the later stage, when the seeds grow into vegetation, they can not only beautify the slope, but also improve the slope's erosion resistance.
