Abstract
Description
Technical Field
[0001] This application relates to the technical field of soil and water conservation, and particularly to a slope protection and maintenance grass curtain net. Background Art
[0002] At present, when excavating river channels or gentle slope foundation pits in water conservancy projects, slopes need to be set, and slope protection needs to be done for the slopes. For general-scale projects, slope protection usually involves constructing soil nail walls and retaining walls, which require materials such as steel mesh, concrete, shale bricks, and mortar. If laying turf or scattering grass seeds on the slope, not only regular maintenance is required but also waiting for the vegetation growth cycle. In case of heavy rain, relying solely on the growth of grass roots for soil fixation has poor effects, and usually, the slope is easily washed away and the soil is easily eroded. If the project scale is too large, the slope is too long, or the foundation pit slope is slightly gentle but the scope is too wide, the required labor cost is too large. Utility Model Content
[0003] In order to save costs and shorten the construction period, this application provides a slope protection and maintenance grass curtain net.
[0004] The slope protection and maintenance grass curtain net provided by this application adopts the following technical solutions:
[0005] A slope protection and maintenance grass curtain net includes fiber weaving layers arranged up and down. At least one set of protection layers is arranged between the two fiber weaving layer structures. A number of stable grids are provided on the protection layer, and grass seeds are sown in the stable grids.
[0006] By adopting the above technical solutions, the grass seeds in the grass curtain net will quickly take root and germinate and grow out from the gaps of the grass curtain net, and the grass roots naturally insert into the slope soil, so that the slope and the grass mat are tightly and firmly combined together, thereby playing a role in protecting the slope, fixing the soil, and preventing landslides.
[0007] Optionally, the slope protection and maintenance grass curtain net further includes a nutrient and moisture retention layer and an insect control and moisture retention layer, and the nutrient and moisture retention layer and the insect control and moisture retention layer are respectively arranged on both sides of the protection layer.
[0008] By adopting the above technical solutions, the nutrient and moisture retention layer stores water and nutrient solution. The nutrient solution provides various nutrient elements required for plant growth, and these elements are gradually released into the stable grids through the action of water, providing continuous nutrient support for the vegetation and accelerating the growth rate of the vegetation. At the same time, the insect control and moisture retention layer stores water and pesticides, effectively inhibiting the breeding and reproduction of pests and providing a healthier growth environment for the vegetation.
[0009] Optionally, the area of the fiber weaving layer is larger than the areas of the protection layer, the nutrient and moisture retention layer, and the insect control and moisture retention layer.
[0010] By adopting the above technical solution, the fiber braided layer serves as the main structure, and its larger area provides stronger support, making the entire slope protection and maintenance grass curtain net more stable. The braiding process of the fiber braided layer ensures good air permeability and water permeability, which is conducive to gas exchange and water penetration in the stabilizing grid, and helps the grass seeds to breathe and grow.
[0011] Optionally, a plurality of first sewing lines arranged horizontally and a plurality of second sewing lines arranged vertically are provided at the fiber braided layer.
[0012] By adopting the above technical solution, a plurality of first sewing lines arranged horizontally and a plurality of second sewing lines arranged vertically are staggered to form a strong grid structure, thereby significantly improving the overall strength and durability of the fiber braided layer, enabling the fiber braided layer to exhibit excellent performance when subjected to tensile, compressive, and shear forces, and reducing the probability of tearing when affected by adverse weather.
[0013] Optionally, the slope protection and maintenance grass curtain net is provided with a third sewing line that captures two layers of the fiber braided layer along the circumferential direction.
[0014] By adopting the above technical solution, the third sewing line can make the multi-layer structure of the grass curtain net more stable, and can effectively prevent the fiber braided layer structure from falling apart under adverse weather conditions such as heavy rain and strong wind.
[0015] Optionally, the first sewing line, the second sewing line, and the third sewing line are made of linen thread or nylon rope.
[0016] By adopting the above technical solution, in order to further improve the performance of the fiber braided layer, the first sewing line, the second sewing line, and the third sewing line are made of high-strength linen thread or nylon rope. These materials not only have excellent mechanical properties but also have good anti-ultraviolet properties, thus ensuring the stability and reliability of the fiber braided layer under long-term sunlight irradiation.
[0017] Optionally, the nutrient moisturizing layer and the pest control and moisturizing layer are an integral structural layer formed by pressing hygroscopic cotton thread.
[0018] By adopting the above technical solution, the hygroscopic cotton thread has good water absorption and water retention capabilities. When the hygroscopic cotton thread is applied to the nutrient moisturizing layer, it can effectively maintain the humidity of the protective layer, provide a continuous and stable water environment for the grass seeds, help with the germination and growth of the grass seeds, and improve the survival rate and growth rate of the grass seeds. On the other hand, when the hygroscopic cotton thread is applied to the pest control and moisturizing layer, it can indirectly reduce the damage of pests to the grass seeds while maintaining the humidity of the protective layer, creating a safer and healthier environment for the growth of the grass seeds.
[0019] Optionally, the fiber woven layer and the protective layer are an integral structural layer made by pressing branches and weeds.
[0020] By adopting the above technical solution, using on-site weeds and branches to process into grass curtain nets for slope protection saves a large amount of labor and material costs, and there is no need to consider the demolition and removal problems after completion.
[0021] In summary, the present application includes at least one of the following beneficial technical effects:
[0022] 1. Effectively reduce the overall cost of the slope protection project. Since on-site materials are used, the material procurement and transportation costs are reduced, and at the same time, the costs of later demolition and cleaning are avoided;
[0023] 2. Significantly shorten the construction period. Due to the rapid laying of the grass curtain net and the rapid growth of vegetation, the greening and stabilization of the slope can be quickly achieved, thus shortening the construction time of the entire slope protection project;
[0024] 3. Improve the stability and durability of the slope protection. The combination of the grass curtain net and the vegetation grown from grass seeds makes the slope soil more stable, effectively preventing soil erosion and landslide phenomena;
[0025] 4. According to different terrain and environmental conditions, the structural shape of the grass curtain net can be adjusted to meet the needs of various slope protection projects. Description of the Drawings

[0029] The following will further describe the present application in detail Figure 1-2 with reference to the attached
[0030] The embodiment of the present application discloses a slope protection and maintenance grass curtain net.
[0031] Such as Figure 1As shown in the figure, the slope protection and maintenance straw curtain net includes a fiber woven layer 1 arranged vertically. At least one set of protection layers 3 are arranged between the structures of the two fiber woven layers 1. A number of stabilizing grids 301 are provided on the protection layer 3, and grass seeds are sown in the stabilizing grids 301. Through this structure, a temporary protection layer 3 can be quickly formed during the slope laying process, avoiding insufficient slope stability caused by factors such as heavy rain. At the same time, it can also promote the growth of grass seeds. The grass seeds in the straw curtain net will soon take root and germinate and grow out from the gaps in the straw curtain net, and the grass roots will naturally insert into the slope soil, making the slope and the grass mat firmly combined together, thus playing a role in protecting the slope, fixing the soil and preventing landslides, and achieving a long-term stable effect.
[0032] The fiber woven layer 1 and the protection layer 3 can adopt an integral structural layer made of branches and weeds. Its structural characteristics include high toughness and strong tensile performance, which are used to resist wind erosion and hydraulic scouring. Using on-site weeds and branches to process into a straw curtain net for slope protection saves a large amount of labor and material costs, adapts to the needs of different geographical environments, and there is no need to consider the problem of demolition and cleaning after completion.
[0033] Specifically, the area of the protection layer 3 is smaller than that of the fiber woven layer 1. At the same time, the protection layer 3 can include multiple parallel layers, each parallel layer is made of branches and weeds, and finally unified into an integral structural layer, so that the protection layer 3 has enough thickness to protect the soil and grass seeds, which helps the grass seeds grow better.
[0034] As Figure 1 and Figure 2 shown in the figure, in order to provide a healthier growth environment for the vegetation, the slope protection and maintenance straw curtain net also includes a nutrient and moisture preservation layer 2 and an insect control and moisture preservation layer 4. The nutrient and moisture preservation layer 2 and the insect control and moisture preservation layer 4 are respectively arranged on both sides of the protection layer 3, and the areas of the nutrient and moisture preservation layer 2 and the insect control and moisture preservation layer 4 are both smaller than that of the fiber woven layer 1. In this embodiment, the nutrient and moisture preservation layer 2 is arranged above the protection layer 3. The nutrient and moisture preservation layer 2 stores water and nutrient solution. The nutrient solution provides various nutrient elements required for plant growth, and these elements are gradually released into the stabilizing grid 301 through the action of water, providing continuous nutrient support for the vegetation and accelerating the growth rate of the vegetation. The insect control and moisture preservation layer 4 is arranged below the protection layer 3. The insect control and moisture preservation layer 4 stores water and pesticides, effectively inhibiting the breeding and reproduction of pests, and providing a healthier growth environment for the growth of vegetation roots.
[0035] Specifically, the nutrient moisture layer 2 and the pest control moisture layer 4 are an integral structural layer pressed from moisture-absorbing cotton threads. The moisture-absorbing cotton threads have good water absorption and water retention capabilities. When the moisture-absorbing cotton threads are applied to the nutrient moisture layer 2, they can effectively maintain the humidity of the protective layer 3, provide a continuous and stable moisture environment for the grass seeds, help with the germination and growth of the grass seeds, and improve the survival rate and growth rate of the grass seeds. On the other hand, when the moisture-absorbing cotton threads are applied to the pest control moisture layer 4, they can indirectly reduce the damage of pests to the grass seeds while maintaining the humidity of the protective layer 3, creating a safer and healthier environment for the growth of the grass seeds.
[0036] To enhance the structural strength of the fiber woven layer 1, a number of first stitching lines arranged horizontally and a number of second stitching lines arranged vertically are provided at the fiber woven layer 1. The slope protection and maintenance grass curtain net is provided with a third sewing line that captures both layers of the fiber woven layer 1 along the circumferential direction. These horizontal first stitching lines and vertical second stitching lines are arranged alternately to form a strong grid-like structure, significantly enhancing the overall strength and durability of the fiber woven layer 1. Therefore, the fiber woven layer 1 can exhibit excellent performance when subjected to tensile, compressive, and shear forces, reducing the probability of tearing when affected by adverse weather. The third sewing line can make the multi-layer structure of the grass curtain net more stable and effectively prevent the fiber woven layer 1 from falling apart under adverse weather conditions such as heavy rain and strong winds.
[0037] Specifically, the first sewing line, the second sewing line, and the third sewing line are woven from linen threads or nylon ropes. To further improve the performance of the fiber woven layer 1, the first sewing line, the second sewing line, and the third sewing line are woven from high-strength linen threads or nylon ropes. These materials not only have excellent mechanical properties but also have good ultraviolet resistance, thus ensuring the stability and reliability of the fiber woven layer 1 under long-term sunlight irradiation.
[0038] The implementation principle of the slope protection and maintenance grass curtain net included in the embodiment of the present application is as follows: By combining the fiber woven layer 1, the protective layer 3, the nutrient moisture layer 2, and the pest control moisture layer 4, a slope protection and maintenance grass curtain net is formed. This slope protection and maintenance grass curtain net can not only provide temporary protection but also promote the growth of vegetation, thus achieving the effect of long-term stabilizing the slope.
[0039] In practical applications, the installation process of the slope protection and maintenance grass curtain net is also very simple. First, lay the grass curtain net on the slope to be protected, ensuring that the fiber woven layer 1 of the grass curtain net is closely attached to the slope surface. Then, fix the grass curtain net to the slope through fixing devices (such as nails, anchor rods, or branches, etc.) to prevent it from shifting under adverse weather conditions.
[0040] In addition, the slope protection and maintenance straw curtain net can also be customized according to different geographical environments and climatic conditions. For example, in arid regions, the thickness of the nutrient and moisture retention layer 2 can be increased to ensure that the grass seeds can still obtain sufficient moisture and nutrients under arid conditions. In rainy regions, the thickness of the nutrient and moisture retention layer 2 can be appropriately reduced to avoid the decay of the slope protection and maintenance straw curtain net caused by excessive moisture.
[0041] In summary, the slope protection and maintenance straw curtain net disclosed in the embodiments of the present application not only has good protection performance, but also can promote the growth of vegetation, thus achieving the effect of long-term stable slopes. Through reasonable structural design and material selection, the straw curtain net can adapt to various geographical environments and climatic conditions and has a wide application prospect.
[0042] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered by the protection scope of the present application.
