Method for performing ecological reinforcement on soil slope surface by utilizing composite curing agent

Abstract

The invention discloses a method for performing ecological reinforcement on the soil slope surface by utilizing a composite curing agent. The method is characterized by comprising steps that a polymer curing agent, mud, water and grass seeds are mixed in proportion to form the composite curing agent, the composite curing agent is sprayed on the soil slope surface to form a curing layer with thickness of about 5-15cm on the soil slope surface, and after plants grow up, the curing layer and root systems of the plants work synergistically to achieve the ecological reinforcement on the soil slope surface. The curing layer has functions of being good in anti-scouring performance, windproof performance and water stability, breathable, capable of holding water and facilitating growth of the plants and the like, and is convenient to construct, low in cost, strong in practical applicability, ecological, and capable of protecting the environment. The method can be widely applied to ecological reinforcement on the soil slope surfaces of roads, bands and the like, further be applied to fields of mining area ecological restoration, engineering area ecological management and the like and be especially suitable for large-scale environmental building construction work, and has good social benefit and economic benefit.

Description

technical field [0001] The invention belongs to the technical field of environmental protection engineering, and in particular relates to a method for ecological reinforcement of a soil side slope with a composite curing agent. Background technique [0002] Strengthening environmental protection is a major task in promoting economic and social development. During the construction of infrastructure such as roads, railways, water conservancy, and mines, the destruction of the original landform vegetation is inevitable. Spoils, rocks, and excavations will leave a large number of exposed slopes in a harmonious natural environment. Slope reinforcement methods mainly include engineering reinforcement and plant reinforcement. Engineering reinforcement usually takes the form of plastering, hammering, spraying, hooking (irrigating) joints, slope retaining walls, etc., but this method is generally only applicable to steep slopes that are not suitable for vegetation growth, and cannot...

Problems solved by technology

Although this method has the advantages of good environmental suitability and the ability to promote plant growth, it still has the following disadvantages: the one is that the curing agent liquid has a relatively high viscosity, poor permeability, and the solidified layer formed on the slope is extremely thin, which cannot meet the requirements on the whole. Slope curing requirements; second, the curing time is extremely long, and it is difficult to guarantee the curing effect in actual operation; third, the curing layer has poor water retention and is easy to dry and crack, which affects the growth of vegetation

Although this method has the advantages of good high and low temperature climate adaptability and aging resistance, it still has the following disadvantages: one is that the curing agent has a short shelf life and is difficult to preserve in practice; the other is that the curing time is extremely short, and within its curing time It is difficult to complete the construction, which will directly affect the construction quality; third, the thickness of the cured layer is thin, and it is difficult to meet the slope reinforcement requirements

Although the solidified layer formed by this method has advantages such as good erosion resistance and wind erosion resistance, it still has the following disadvantages: the one is that the curing time is extremely short, and it is difficult to complete the construction within the curing time; It is difficult to meet the slope reinforcement requirements; the third is that the curing agent is diluted and sprayed directly on the sand after sowing vegetation grass seeds, which is easy to cause the displacement of grass seeds, and the uniformity of vegetation distribution on the slope is extremely poor

[0006] To sum up, how to overcome the deficiencies of existing technologies and effectively solve the problems of loose soil quality, reduced water content, and easy weathering caused by excavation in the course of environmental development and construction, resulting in ecological system imbalance, damage to native vegetation, or exposed soil slopes? , It is easy to cause disasters such as slope erosion, soil erosion, slope collapse, river blockage, landslides, water pollution, etc., which has become one of the key problems to be solved in the field of environmental protection engineering technology
