An ecological restoration system for coal mining traces

Abstract

The invention discloses an ecological restoration system for coal mining traces, which comprises a water-absorbing fiber braided mesh layer laid under the soil layer of the coal mining trace, a hollow fixing screw for fixing the water-absorbing fiber braided mesh layer, and a water-absorbing fiber braided mesh fixed on the water-absorbing mesh. The planting unit on the fiber braided mesh layer; the water-absorbing fiber braided mesh and the water-absorbing fiber braided mesh layer are braided together on three sides, and the remaining side is fixedly connected by a buckle and a mounting block with a buckle connection port; the hollow fixing screw is from top to bottom The bottom of the screw body is hollow and the movable cover is screwed to the upper opening of the screw body. The screw body is evenly provided with a number of water outlet holes with miniature one-way valves. The inner wall of the screw body is evenly coated with an anti-corrosion coating. The invention realizes the stable fixation of the plants, enables the roots of the plants to go deep into the soil, ensures the requirements of water and nutrients in the process of plant growth, and has high seed germination rate and survival rate.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an ecological restoration system for coal mining traces. Background technique [0002] Due to the development of mineral resources and other reasons, a large number of slope structures with unstable geological structures, poor preparation coverage and high soil pollution appear around the mine. Causing serious geological disasters such as landslides and landslides, on the other hand, it is also easy to cause environmental pollution such as dust and groundwater pollution. In response to this problem, the current main treatment method is: grid greening, that is, to first divide the exposed slope Make multiple grids and build them with cement and steel bars, then mix the plant seeds with the soil suitable for the growth of plant seeds and put them in plastic bags, put the plastic bags into the square grass grids, and rely on timing to place them in the square grass gr...

AI Technical Summary

Problems solved by technology

Although this method can make the exposed hillside green quickly, the problems that exist are: 1. Adopting reinforced concrete to build the square grass grid, the project is large and the cost is high; 3. The soil suitable for seed growth is placed in a plastic bag, and the sprayed water or rainwater tends to flow away along the surface of the plastic bag, making it difficult to penetrate into the soil. 4. There is a layer of plastic film between the soil and the hillside soil layer. After the plants grow, the roots cannot go deep into the hillside soil layer. When the typhoon comes, the plants are easily uprooted and cannot play a good role. water retention and soil stabilization
