Abstract

The invention discloses a multifunctional combined type ecological slope protection substrate. The multifunctional combined type ecological slope protection substrate is made of sandy soil, cement, organic materials, polypropylene fibers, superphosphate, diammonium phosphate, monopotassium phosphate, potassium polyacrylate, potassium nitrite, potassium sulfate and soil activation fungicide by uniformly mixing and can create the soil environment which is reasonable in structure, anti-freezing, anti-scouring, high in fertilizer efficiency and activation potential and long in water retention and drought enduring property for the bare slope in the high and cold area, so that damaged slope vegetation can be restored; the materials used by the slope protection substrate are low in cost, convenient to construct and high in technical operability and has wide application prospect.

Description

technical field [0001] The invention relates to the technical field of slope protection, in particular to a multifunctional combined ecological slope protection base material. 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 community calls this artificial soil the ecological slope protection substrate. [0003] The development and construction of energy and transportation in alpine regions have brought devastating damage to the extremely fragile regional ecological environment, and many rocky exposed slopes caused by engineering disturbances urgently need vegetation restoration. The salient features of the alpine region are the low annual average temperature, the long duration of the frost period, and the extreme minimum temperature can often reach -40°C. Under such conditi...
