Abstract

The invention disclose a soft rock slope soil preventing curing agent which is prepared from the following raw materials: compound resin, chloroprene rubber, maize straws, polyacrylic acid, cement, polyvinyl amine, polyoxyethylene, polyvinyl acetate, polyasparaginic acid, ammonium sulfate and a curing auxiliary agent. The curing agent is good in adhesive property, curing property, flowing propertyand peaceability. Being in contact with a soil mass, high molecular chains diffuse, permeate and wind the surfaces of soil particles and inside of pores to from a netty membrane structure. Meanwhile,a lot of functional groups on the high molecular chains are combined with soil particles through action of chemical bonds, so that the water stability of the soil particles is improved, and meanwhile, the hydrophilic nature on the surfaces of the soil particles are changed to form an effective water repellent ability, so that the erosion resistibility and the weather-proof ability of the soil mass are improved. The curing agent can interact with the soil to bring the benefit of growth and development of vegetations, and can be sprayed and sowed in soil replacement for ecological protection based on curing of the soft rock slope.

Description

technical field [0001] The invention relates to the field of slope protection. It particularly relates to a soft rock slope soil protection curing agent. Background technique [0002] Soft rock is a complex rock mechanical medium with significant plastic deformation in a specific environment. The basic mechanics theory and research methods of soft rock have been studied in depth. Over the years, the basic concepts of soft rock and soft rock engineering slope design And other theoretical issues, there has been no conclusion at home and abroad, which has brought a lot of inconvenience to soft rock engineering slopes. Soft rock engineering refers to rock mass engineering related to large plastic deformation engineering rock mass, such as soft rock tunnel engineering, soft rock slope engineering and so on. Regarding the definition of soft rock, there are many different interpretations, including descriptive definitions: (1) Soft rock formation refers to loose and weak rock for...
