Abstract

The invention belongs to the technical field of slope protection, and provides an antifreeze type ecological slope protection substrate which is formed by evenly mixing of plant growth soil, cement, humus, concrete afforesting additives, silica powder and palm fibers. The antifreeze type ecological slope protection substrate can create vegetation habitat which is reasonable in structure, good in hydraulic scour resistance and freezing resistance and high in fertilizer efficiency for bare rock slopes in a frigid region so as to restore damaged slope vegetation. Raw materials of the antifreeze type ecological slope protection substrate are low in price and convenient to use, and the antifreeze type ecological slope protection substrate is strong in technical operability and has broad application prospect.

Description

technical field [0001] The invention relates to the technical field of slope protection, in particular to an assembly method of an ecological slope protection base material with high frost resistance, which can create a suitable vegetation habitat for vegetation restoration of exposed rock slopes in alpine regions. Background technique [0002] At present, the common method of vegetation restoration on exposed rock slopes is to first create a soil environment for plant growth on the slope surface, and then gradually realize vegetation restoration. The engineering circles call this artificial soil the ecological slope protection base material, which is composed of plant soil, humus, Several kinds of water-retaining agent, binder, fertilizer and other materials are combined in a certain proportion. This kind of ecological slope protection base material was previously developed for areas with high temperature conditions such as South China, Central China and Southwest China. Du...
