Dry spraying and wet spraying combined vegetation concrete ecological restoration method for high and steep slope

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.
