Embodiment 1

[0034] The weakly weathered rock slope of a highway in Yichang City, Hubei Province, with a slope of 60°. It is proposed to adopt the present invention to carry out ecological slope protection.

[0035] First, pre-treat the slope surface, remove loose matter such as floating soil, pine rocks, and floating roots on the slope surface to keep the slope surface flat, and lay a flat barbed wire mesh with a diameter of 2 mm and a mesh size of 3.0 cm×3.0 cm on the slope surface ( Rust removal and anti-corrosion treatment), and fixed with hot-rolled ribbed steel bars with a diameter of 16 mm, the distance between the anchor rods is 1 m, the insertion slope is 0.3 m, and the exposed area is 10 cm. The distance between the plane net and the slope is 7cm, and planting rods with a diameter of 70 mm are arranged between the plane net and the slope, with a distance of 1.5m. The net and the anchor, the hanging net and the planting stick, and the hanging net are tied with wire firm. Accordi...

Embodiment 2

[0044] A hydropower station in the upper reaches of the Jinsha River has a slope of 70° on the lower bank of the access road. It is proposed to adopt the present invention to carry out ecological slope protection.

[0045] First, pre-treat the slope surface, remove loose matter such as floating soil, pine rocks, and floating roots on the slope surface to keep the slope surface flat, and lay a flat barbed wire mesh with a diameter of 3 mm and a mesh size of 4.0 cm×4.0 cm on the slope surface ( Rust removal and anti-corrosion treatment), and fixed with hot-rolled ribbed steel bars with a diameter of 18 mm, the distance between the anchor rods is 0.8m, the insertion into the slope is 0.4m, and the exposed area is 10cm. The distance between the plane net and the slope is 6cm, and planting rods with a diameter of 60 mm are arranged between the plane net and the slope at a distance of 0.8m. The net and the anchor, the hanging net and the planting stick, and the hanging net are bound...

Embodiment 3

[0054] The excavation slope of a mine in Jincheng, Shanxi has a slope of 80°. It is proposed to adopt the present invention to carry out ecological slope protection.

[0055] Firstly, pre-treat the slope surface, remove loose matter such as floating soil, pine rocks, and floating roots on the slope surface to keep the slope surface flat, and lay a flat barbed wire mesh with a diameter of 4 mm and a mesh size of 5.0 cm × 5.0 cm on the slope surface ( Rust removal and anti-corrosion treatment), and fixed with hot-rolled ribbed steel bars with a diameter of 20 mm, the distance between the anchor rods is 0.6m, the insertion into the slope is 0.5m, and the exposed area is 10cm. The distance between the plane net and the slope is 5cm, and planting rods with a diameter of 50 mm are arranged between the plane net and the slope, with a distance of 0.6m. The net and the anchor, the hanging net and the planting stick, and the hanging net are tied with wire firm. According to the formul...

Abstract

The invention provides a dry spraying and wet spraying combined vegetation concrete ecological restoration method for a high and steep slope, which is characterized in that on the basis of the original dry spraying vegetation concrete technology, spray-seeding is improved into three layers, namely a base layer, a surface layer and a protective layer, the surface layer is constructed by adopting a dry spraying machine, and the base layer and the protective layer are constructed by adopting a wet spraying machine; on the basis of an original dry spraying vegetation concrete formula, the cement consumption is reduced, and the integrity and adhesiveness of a base material are maintained by adding tree fibers, polyvinyl alcohol and fly ash; the protective layer is a mixture of pure tree fibers and polyvinyl alcohol, replaces coverage of non-woven fabrics, has the characteristics of water retention, heat preservation, air permeability and the like, and provides anti-scouring capacity for the base material in the early stage of spray seeding; the coated slow-release compound fertilizer is adopted to replace part of common compound fertilizer, nutrients are provided for a long time in the base material, and the later-period nutritional condition of the base material is improved; the shrub seeds are mixed and put into the base layer, and the herbal seeds are mixed and put into the surface layer.

Description

technical field [0001] The invention relates to the field of slope ecological protection, in particular to a vegetation concrete ecological restoration method for high and steep slopes combined with dry spraying and wet spraying and a detection method thereof. Background technique [0002] In recent years, the development of many large-scale construction projects such as roads, railways, and hydropower stations has occupied a large amount of land, destroyed surface vegetation, caused serious soil erosion, and even caused hazards such as landslides, mudslides, and mountain torrents. A large number of natural habitats have been lost, the ecological environment is seriously unbalanced, and plants grow extremely slowly in this environment. In response to these phenomena, scholars and engineers from various countries have developed a series of vegetation restoration technologies in engineering disturbed areas to speed up the ecological restoration of disturbed areas. Better socia...
