Abstract

The invention relates to a method for synergistically improving the strength and a long-acting repairing function of an ecological slope protection base material by using zeolite and biomass charcoal and is applied to the technical field of slope protection and ecological repairing. The method comprises the following steps: the ecological slope protection base material is prepared from planting soil, cement, an organic material and a habitat base material modifier according to a dry material mass ratio, and then the biomass charcoal and the zeolite are uniformly mixed in proportion, stirred into the ecological slope protection base material, and subjected to spraying and seeding on the side slope by using an air compressor. According to the method, the ecological slope protection base material has the advantages of more hydrated cement, higher strength, higher nutrient immobilization capability and more lasting ecological restoration function, and has remarkable practical significance in engineering application of the ecological slope protection base material.

Description

technical field [0001] The invention relates to the technical field of slope protection and ecological restoration, in particular to a method for synergistically improving the strength and long-term restoration function of ecological slope protection substrates by utilizing zeolite and biomass charcoal. Background technique [0002] With the rapid development of economic construction, my country's infrastructure construction is in full swing, road construction, hydropower project construction, mining, etc. will inevitably form many damaged slopes, and ecological protection technology has emerged as the times require. In our country, after decades of development, the sustainable development of the ecological environment has become a consensus, and the restoration of ecological functions of damaged slopes is becoming an important indicator of regional ecological quality evaluation. At present, the most widely used and most effective ecological protection technologies in my cou...
