Study on Construction Technology of Ecological Protection of Straw Brick on Highway Slope
In order to protect highway slope,prevent mountain landslide and soil erosion,and solve the prob-lems of grass seed being washed away by rain and low survival rate of plants in the initial stage of protection,the construction technology of ecological protection of highway slope straw brick is adopted,taking corn straw as raw material,adding soil,water and a small amount of starch binder,the straw brick with holes was formed by high strength extrusion,and was applied together with the black soil(planting soil)cushion containing grass seeds,and filling planting soil between holes and pores of straw brick,which is used in highway slope protection construction.The technique effectively avoids the slope surface from rain erosion,strengthens the surface soil of the slope,pre-vents soil and water loss,protects the newly excavated slope in time,ensures the stability of the roadbed,and re-stores the ecological environment,reduces the cost of the project,and saves energy and environmental protection.
