Description

Technical Field

[0001] The utility model belongs to the technical field of ecological restoration, and specifically relates to a self-anchored assembled slope ecological restoration device with simple structure, wide slope adaptability, high construction efficiency and low cost. Background Art

[0002] Slope ecological restoration is a new slope protection technology developed in recent years, which is widely used in engineering fields such as mine slopes, highway slopes, and municipal slopes. For slope ecological restoration projects on flat sites and gently sloping areas, relatively mature conventional slope ecological restoration technologies such as on-site seeding greening, transplanting greening, and prefabricated paving greening are generally used; however, in mines and municipal engineering construction projects in mountainous and hilly areas, the exposed slopes formed by earth filling and excavation will destroy the existing vegetation and landforms, change the original stress state of rock and soil, cause soil erosion, and cause environmental and ecological problems. It is necessary to carry out slope ecological restoration on the rock and soil slopes formed by engineering construction. For slope ecological restoration of exposed slopes with large slopes, due to the limitations of site and space, there are not many technologies to choose from. Under the condition of stable slopes, spray greening technology or frame beam slope protection greening technology are mostly used.

[0003] Spraying greening technology: It is suitable for rock slopes with a slope ratio of less than 1:0.5. There are construction technologies such as hydraulic spraying, pellet spraying, and imported soil vegetation concrete. It is suitable for various soils, rock slopes and concrete slopes. The principle of spraying greening is: laying a wire mesh on the slope and anchoring the wire mesh in the rock and soil with anchor rods. After mixing plant seeds, water, adhesives, fertilizers, nutrient soil, soil stabilizers, soil improvers, etc. in a certain proportion using spraying equipment, spray them on the surface of the slope where the net is laid through special spraying equipment to form a uniform matrix covering layer. The matrix covering layer is mixed with plant seeds according to the ratio, and relies on the interweaving of fibers and the viscosity of the aqueous solution to connect and adhere to the surface, creating conditions for plant growth, and playing a role in conserving water, greening slopes and stabilizing slopes, and preventing soil erosion. Spraying greening construction process: Slope cleaning and trimming → interception and drainage system construction → laying nets → spraying → maintenance.

[0004] Frame beam slope protection and greening technology: It consists of frame beam slope protection structure engineering and frame beam internal vegetation bags. The principle is: 1. The function of the frame beam slope protection structure is to stabilize and protect the slope. It is composed of cast-in-place reinforced concrete well-shaped beams. First, the anchor rods (cables) are driven into the rock and soil body, and then the frame beam structure connected with the anchor rods (cables) is constructed. The frame beam and the slope rock and soil body are connected together by the tension of the anchor rods (cables) to improve the stability of the slope. 2. Vegetation bags are built in the well-shaped frame beam. Vegetation bags use special equipment and production processes to plant grass seeds, fertilizers, water-retaining agents, etc. on non-woven fabrics at a certain density, and then form bag-shaped products through machine rolling and other processes. Vegetation bags provide a medium for plant growth. After the plants grow, the roots pass through the vegetation bags, penetrate into the slope and combine with the slope soil layer, which can stabilize the slope, ensure that the water and soil on the slope surface are not lost, and play a role in protecting the slope surface and greening the environment. Construction process of frame beam slope protection and greening: trimming the slope surface → drilling holes → making and installing anchor rods (cables) → grouting in holes → frame beam construction → anchor cable tensioning and anchoring → backfilling → laying vegetation bags in the frame → greening maintenance.

[0005] The above two technologies have their own advantages, but both have the following disadvantages to varying degrees: 1. There are certain restrictions on the slope of the slope. 2. It is necessary to prepare the matrix cover layer on site, or pre-fabricate the concrete frame structure, and the construction period is long. 3. The construction requires special machinery and materials, and has specific requirements on the skills of the construction operators. Utility Model Content
