A kind of soil slope protection method

Abstract

The invention discloses a soil slope protection method and belongs to the technical field of environmental protection engineering. The soil slope protection method comprises the following steps: slope surface trimming including that a slope surface is leveled; curing agent preparation including that 16.8-22.91 parts of a cellulose curing agent solution, 18.18-24.79 parts of a macromolecular curing agent solution, 6.12-8.35 parts of an additive solution and 43.96-58.9 parts of water are uniformly mixed to form a curing agent; stabilized soil preparation including that 10 parts of slope soil and 2.5-4 parts of the curing agent are mixed; stabilized soil paving including that tap water is sprinkled onto the trimmed slope surface to wet the slope surface, and cured mud is paved on the slope surface; and stabilized soil conservation including that a stabilized layer is covered with a mulching film, and after grass seeds sprout, the mulching film is removed to obtain a stabilized layer formed by conservation. The soil slope protection method is more uniform in stabilization and higher in stabilization strength, allows large-area on-site construction and has higher applicability.

Description

technical field [0001] The invention relates to the technical field of environmental protection engineering, in particular to a soil slope protection method. Background technique [0002] For a long time, a large number of exposed slopes have been left in the process of spoil, rock spoil, excavation, etc., especially in the arid area of ​​Northwest China. It is difficult to recover after the original vegetation is destroyed. If the retreat and steepening are not dealt with in time, further development will lead to collapse and landslide of the slope, which will seriously affect the operation of the facilities. Traditional slope reinforcement methods, such as sash, face wall and spraying protection, etc., are mostly built with inorganic binders such as grouted rubble and concrete. The rigid combination of materials and soil slopes will fall off and deform after long-term exposure, and block the Vegetation grows. [0003] By combining grass planting with traditional slope re...

Problems solved by technology

[0009] In order to overcome the defects of the above-mentioned prior art, the present invention provides a soil slope slope protection method. The present invention adopts the method of combining chemical reinforcement and flexible support to form a layer on the surface of the slope with excellent erosion resistance and wind erosion resistance and is suitable for Compared with the existing technology, the slope protection layer with vegetation growth has more uniform reinforcement and higher reinforcement strength. It can be constructed on a large area and has wider applicability. It can solve the long-term sun and rain on exposed soil slopes on a large scale. Water and soil loss caused by rain, snowmelt erosion, ecological environment deterioration, slope landslides and other problems
