Description

Technical Field

[0001] The invention relates to the field of slope protection structures, in particular to a vegetative concrete ecological slope protection structure. Background Art

[0002] Vegetated concrete ecological slope is a new type of slope protection technology that organically combines engineering protection with ecological restoration. While achieving slope stability, it can also improve the ecological environment. Its principle is: Using porous concrete as a framework, biocompatible materials are filled into the pores and covered. Plant seeds are then mixed into the biocompatible materials. After incubation, plants germinate and grow, with their roots extending and extending through the pores of the concrete. This seamless integration of plants and concrete creates an environmentally friendly slope protection material with a certain strength and vegetation coverage. The primary material composition is porous concrete: a mixture of coarse aggregate of varying particle sizes, a small amount of fine aggregate (optional), cement, water, and an ecological vegetation concrete slope protection enhancer, mixed in a specific proportion, poured, and naturally cured. The resulting surface has a candy-like texture and numerous interconnected, fine pores. Biocompatible materials typically include sandy loam, organic materials, and organic fertilizers, providing essential nutrients and water for plant growth. Plant seeds: Select appropriate grass, flower, or shrub seeds, such as ryegrass and tall fescue, based on local climate and soil conditions to achieve optimal vegetation coverage and ecological benefits. The advantages of vegetated concrete ecological slopes are as follows: Protection: Concrete has high compressive strength and, combined with the plant root system, can play a good role in slope protection, effectively preventing slope collapse and soil erosion. Landscape: Plants grow on the surface of concrete and have a high coverage, which can maintain a good landscape effect, integrate the slope with the surrounding natural environment, and enhance the beauty of the environment. Water permeability: The large pore structure allows rainwater to quickly penetrate into the ground, which not only avoids the harm caused by floods, but also replenishes groundwater, helping to maintain the stability of the groundwater level and the humidity of the soil. Purification: The filler in the gaps can filter impurities and allow microorganisms to survive. It can purify water quality and improve the surrounding water environment to a certain extent. Environmental protection: Compared with traditional concrete, vegetated concrete does not use sand, and the amount of cement is reduced by 1 / 4-1 / 3, which has a lower load on the environment and meets the requirements of sustainable development.

[0003] For example, the patent application number 202420284671.4 discloses a vegetative concrete ecological slope protection structure, which relates to the field of slope reinforcement protection and ecological restoration technology. The vegetative concrete ecological slope protection structure includes: a plurality of vegetative concrete prefabricated blocks, which are combined with each other to form a slope protection paving layer; wherein, the outer wall of the vegetative concrete prefabricated block is provided with a slot, and the outer wall of the vegetative concrete prefabricated block is also provided with an insert that matches the slot. Vegetative concrete is a porous concrete with a certain pore size and porosity that has been vigorously developed and promoted for the protection of the ecological environment. The concrete pores are filled with nutrients required for plant growth. Plants grow on the surface of the concrete, and the roots penetrate the internal pores of the concrete to form an organic combination of plant-skeleton-soil. Connecting pins are used to further connect the vegetative concrete prefabricated blocks to strengthen the tightness of the connection between the vegetative concrete prefabricated blocks.

[0004] The patent with application number 202122267387.5 discloses a vegetated concrete ecological slope protection, which relates to the field of slope protection. It includes a nutrient substrate layer, a vegetated concrete base layer, a reinforcement net and a vegetated concrete surface layer from the inside to the outside; the reinforcement net is fixedly connected with a plurality of anchor rods for anchoring to the slope; the reinforcement net includes a plane part and a plurality of protrusions fixedly connected to the plane part, the protrusions are an upper protrusion and a lower protrusion, the lower protrusion protrudes toward the side where the vegetated concrete base layer is located, and the upper protrusion protrudes toward the side where the vegetated concrete surface layer is located, and the protrusions are arranged horizontally and at intervals along the inclined downward direction of the reinforcement net.

[0005] Patent application number 202221270759.8 discloses a protective highway ecological slope, including an ecological slope body, wherein the ecological slope body is composed of an upper protective beam, a lower protective beam, and a side protective beam. A planting cavity is provided inside the ecological slope body, and a first drainage pipe is installed through the surface of the upper protective beam. By passing the ecological slope body through the upper protective beam, the lower protective beam, and the side protective beams, the planting cavity inside the ecological slope is more stable. At the same time, a first drainage pipe and a second drainage pipe are respectively installed through the surfaces of the upper and lower protective beams, so that rainwater can be discharged in a timely manner when encountering heavy rainfall. In addition, a gravel layer is provided inside the planting cavity on one side of the second drainage pipe, and a mortar layer is laid above the gravel layer, so that the soil layer inside the planting cavity can be effectively protected to prevent it from being lost through the second drainage pipe, thereby improving the overall stability of the ecological slope body and improving its protective performance.

[0006] The vegetation that can be planted in the above-mentioned vegetated ecological slopes and similar ecological slopes is often small-sized, and large plants such as trees cannot be grown. The reason is that the gaps between the filled aggregates are small, which limits the growth of vegetation and thus limits the ability of the ecological slope to prevent slope collapse and soil erosion.

[0026] When in use, place two concrete slope protection frames 4 side by side so that the threaded holes on the first connecting block 12 and the threaded holes on the second connecting block 3 are in the same straight line, and then use connecting screws to connect the threaded holes on the first connecting block 12 and the threaded holes on the second connecting block 3 at the same time to fix the two concrete slope protection frames 4 together. Similarly, several concrete slope protection frames 4 can be fixed together.

[0027] The recycled aggregate 10 inside the concrete slope protection frame 4 is located between two limit plates 11. The limit plates 11 are located inside the concrete slope protection frame 4.

[0028] The left and right ends of the guide rod 8 are both sleeved with pistons 14, which are slidably connected to the guide rod 8. The piston 14 is made of silicone. The piston 14 is located in the nutrient solution storage cylinder 6. The piston 14 slides with the inner wall of the nutrient solution storage cylinder 6. The nutrient solution storage cylinder 6 is fixed to the concrete slope protection frame 4. The nutrient solution storage cylinder 6 is filled with nutrient solution. The piston 14 closes the nutrient solution storage cylinder 6 to prevent the nutrient solution from flowing out. The left and right ends of the guide rod 8 are both provided with connecting pipes 19, which are fixed to the guide rod 8. The connecting pipe 19 is connected to the inside of the guide rod 8. A number of nozzles 9 are provided on the guide rod 8. The nozzles 9 are located on the side of the guide rod 8. The nozzles 9 are fixed to the guide rod 8.
