Description

Technical Field

[0001] This utility model belongs to the field of slope protection technology in geotechnical engineering, and specifically relates to a prefabricated ecological slope protection structure. Background Technology

[0002] Traditional slope protection structures have long relied on rigid materials such as concrete grids, masonry, or geogrids. While these technologies can provide stable protection to some extent, their ecological benefits are extremely limited. The use of rigid slope protection materials often disrupts the ecological balance of natural slopes, leading to the isolation of soil and vegetation, making it difficult for the slope to restore its natural ecological function. In contrast, flexible ecological slope protection technologies, such as three-dimensional mesh mats, show certain advantages in promoting vegetation growth, but the problem of insufficient material strength remains difficult to overcome. These flexible materials are easily eroded and damaged when faced with large water flows, especially in areas prone to heavy rain or floods, where their protective performance is often unsustainable. In existing technologies, the combination of grass seeds and nutrient layers is mostly achieved through on-site mixing and laying. This method not only leads to uneven distribution of grass seeds but also easily causes nutrient loss, ultimately resulting in low vegetation survival rates and difficulty in forming a stable vegetation cover. Summary of the Invention

[0003] The main purpose of this utility model is to provide a prefabricated ecological slope protection structure that achieves rapid assembly through modular design and improves the ecological performance and engineering reliability of the slope protection by combining the synergistic effect of the grass seed layer, nutrient layer and support mesh layer.

[0004] Therefore, the present invention provides a prefabricated ecological slope protection structure, wherein the ecological slope protection is composed of several prefabricated modules. Each prefabricated module includes a support mesh layer, a nutrient layer disposed on the support mesh layer, and a grass seed layer disposed on the nutrient layer. Herbaceous plants are pre-cultivated in the grass seed layer, and the roots of the herbaceous plants connect the support mesh layer, the nutrient layer, and the grass seed layer into a whole.

[0005] Specifically, adjacent prefabricated modules are joined together using a splicing assembly, which includes eco-friendly nails and straps. Multiple eco-friendly nails are inserted into the prefabricated modules on both sides of the splicing seam, and the two ends of the straps are wrapped and fixed to the corresponding eco-friendly nails on the prefabricated modules on both sides of the splicing seam. Alternatively, the splicing assembly includes a splicing plate and connecting pins. The two ends of the splicing plate rest on the prefabricated modules on both sides of the splicing seam, and the connecting pins pass through the through holes at both ends of the splicing plate and are inserted into the corresponding prefabricated modules.

[0006] Specifically, the splicing board is a bamboo board or a polylactic acid composite board.

[0007] Specifically, the support mesh layer is made of coconut fiber mesh or polylactic acid woven mesh.

[0008] Specifically, the ecological slope protection is fixed to the slope surface by a number of anchor rods, which penetrate the ecological slope protection and insert into the stable strata of the slope surface.

[0009] Specifically, the anchor bolts are made of bamboo or polylactic acid.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. Modular prefabrication technology reduces the complex procedures of traditional on-site construction through industrialized production, especially in complex terrain or severe weather conditions, which significantly shortens the construction cycle, reduces labor costs, and significantly reduces labor input and construction risks.

[0012] 2. The integrated design of the grass seed layer and the nutrient layer significantly improves the efficiency of vegetation cover. Through the composite pressing process, the grass seeds are evenly distributed in the water-retaining agent and humus substrate. The integrated design reduces the need for later manual replanting and fertilization, thus reducing maintenance costs.

[0013] 3. The supporting mesh layer adopts a high-strength flexible woven structure. The mesh design allows vegetation roots to penetrate freely, forming a vegetation-mesh layer composite protection system that adapts to different hydrological conditions and significantly enhances the slope's resistance to erosion.

[0014] 4. The application of fully degradable materials reduces the environmental burden and aligns with green construction principles. The support mesh layer uses plant fiber woven mesh or polylactic acid reinforced mesh, and the anchoring system uses bamboo or PLA anchors. These materials gradually degrade into harmless substances after their function is complete, integrating into the soil and improving fertility. The full life-cycle design of the materials avoids the pollution problems of traditional plastic mesh and metal anchors, while promoting ecological restoration and providing a sustainable solution for green infrastructure construction.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] See Figures 1-3 A prefabricated ecological slope protection structure is constructed by splicing together several prefabricated modules. Each prefabricated module includes a support mesh layer 3, a nutrient layer 2 set on the support mesh layer 3, and a grass seed layer 1 set on the nutrient layer 2. Herbaceous plants are pre-cultivated in the grass seed layer 1, and the roots of the herbaceous plants connect the support mesh layer 3, the nutrient layer 2, and the grass seed layer 1 into a whole.

[0026] In this embodiment, the integrated design of grass seed layer 1 and nutrient layer 2 significantly improves vegetation coverage efficiency. Through composite pressing process, grass seeds are evenly distributed in water-retaining agent and humus matrix. The integrated design reduces the need for later manual replanting and fertilization, reduces maintenance costs, and the industrial production of prefabricated modules reduces the difficulty of on-site construction.

[0027] Specifically, the seed layer 1 uses a composite pressing process of grass seeds and water-retaining agents. Mechanical pressing ensures uniform distribution of the grass seeds, while the slow-release properties of the water-retaining agents extend the water supply period during the initial growth stage, providing a stable microenvironment for vegetation germination. The nutrient layer 2, through an optimized ratio of humus and organic fertilizer, forms an ecological substrate that slowly releases nutrients, improving soil structure while avoiding the nutrient loss problems associated with traditional fertilizers. Specifically, the seed layer 1 mixes grass seeds, water-retaining materials, and an environmentally friendly binder to ensure uniform seed distribution and slow water release; the nutrient layer 2 uses a 3:1:1 ratio of humus, organic fertilizer, and soil conditioner to form a slow-release nutrient substrate.

[0028] Specifically, such as Figure 3 As shown, adjacent prefabricated modules are joined together using a splicing assembly, which includes eco-friendly nails 9 and binding straps 10. Multiple eco-friendly nails 9 are inserted into the prefabricated modules on both sides of the splicing seam, and the two ends of the binding straps 10 are wrapped and fixed to the corresponding eco-friendly nails 9 on the prefabricated modules on both sides of the splicing seam, thereby connecting the two prefabricated modules. Of course, the splicing assembly can also adopt another form, such as... Figure 4 As shown, the splicing assembly includes a splicing plate 4 and connecting pins 5. The two ends of the splicing plate 4 rest on the prefabricated modules on both sides of the splicing seam. The connecting pins 5 pass through the perforations at both ends of the splicing plate 4 and are inserted into the corresponding prefabricated modules, thereby connecting the two prefabricated modules. The splicing plate 4 is made of bamboo or polylactic acid composite board, and the connecting pins 5 are made of bamboo or polylactic acid.

[0029] In this embodiment, all splicing components are made of biodegradable materials. After the biodegradable materials have completed their function, they gradually transform into soil organic matter, which not only eliminates plastic pollution but also improves soil fertility.

[0030] Specifically, support layer 3 uses a high-strength flexible woven mesh, combining tensile strength and elastic adaptability. While dispersing the impact energy of water flow, it allows vegetation roots to penetrate, forming a vegetation-mesh composite protection system that significantly enhances slope stability. Support layer 3 can be made of coconut fiber or polylactic acid (PLA). The application of environmentally friendly materials is consistent throughout the entire slope protection system. Support layer 3 uses plant fiber woven mesh or PLA-reinforced mesh; these biodegradable materials gradually transform into soil organic matter after their function is complete, eliminating plastic pollution and improving soil fertility.

[0031] See Figure 5In some embodiments, the ecological slope protection is fixed to the slope surface by several anchor rods 6. The anchor rods 6 penetrate the ecological slope protection and are inserted into the stable strata of the slope surface. The anchor rods 6 are made of bamboo or polylactic acid. After the modules are assembled, the ecological slope protection is fixed to the slope body 7 with the anchor rods 6. The spacing and depth of the anchor rods 6 should be determined according to the geological conditions and design requirements of the slope surface. Usually, the spacing of the anchor rods 6 is 1-2 meters and the depth is 0.5-1 meter.

[0032] In this embodiment, ecological slope protection can be designed and prefabricated with suitable prefabricated modules based on the slope's topography, gradient, and geological conditions. The size and shape of the modules should be adjusted according to the specific requirements of the slope, and they can typically be prefabricated as rectangular or arc-shaped modules to adapt to different slope conditions. During module prefabrication, ensure the uniform distribution and tight bonding of the grass seed layer 1, nutrient layer 2, and support mesh layer 3. Drainage micropores 8 are provided on the module surface, with a pore diameter of 2-5mm and a spacing of 50-100mm, to ensure the slope's drainage performance. The drainage micropores 8 are designed to prevent water flow from eroding the slope while ensuring timely drainage of water from the slope, reducing the erosion of the slope by accumulated water.

[0033] After the prefabricated modules are laid, vegetation maintenance is carried out, including regular watering to keep the soil moist and promote seed germination and vegetation growth. In the early stages of vegetation growth, appropriate fertilization can be applied to provide additional nutrient support. As the vegetation gradually covers the area, the ecological functions of the composite layer will be fully realized, forming a stable vegetation-net composite protection system. The integrity and stability of the composite layer modules should be checked regularly, especially during the rainy season and flood periods, ensuring that the connections between modules are secure and that the anchors 6 and ecological nails 9 are not loose. Any vegetation damage or soil erosion should be repaired and replanted promptly to ensure the long-term effectiveness of the slope protection system.

[0034] The above-mentioned ecological slope protection construction process is as follows:

[0035] Step 1: Design and prefabricate precast modules based on the slope's topography, gradient, and geological conditions. The size and shape of the modules should be adjusted according to the specific requirements of the slope; they can typically be prefabricated as rectangular or curved modules to adapt to different slope conditions.

[0036] Step 2: Clean the slope surface, removing debris, loose soil and stones. Fill and repair any cracks or depressions on the slope surface to ensure the stability of the module laying.

[0037] Step 3: Transport the prefabricated modules to the construction site and assemble them using splicing components according to the slope direction and design requirements.

[0038] Step 4: Set drainage micro-holes 8 on the surface of the module, with a hole diameter of 2-5mm and a hole spacing of 50-100mm.

[0039] Step 5: After the modules are assembled, determine the spacing and depth of the anchor rods 6 according to the slope conditions, and select bamboo or PLA biodegradable anchor rods 6 to penetrate the potential sliding surface at an inclination angle of 15°-30°.

[0040] Step Six: After the modules are laid, carry out vegetation maintenance work to form a stable vegetation-net composite protection system.

[0041] Step 7: After construction, regularly check the stability of anchor bolt 6 to ensure that the degradation cycle is synchronized with the maturity of the vegetation root system, so as to achieve a seamless transition from "mechanical anchoring to ecological self-stabilization".
