Frost-resistant habitat base material for alpine region and preparation method thereof

Abstract

The invention relates to a frost-resistant habitat base material for alpine region and a preparation method thereof, which are applied to the fields of slope ecological protective engineering, landscape greening engineering and the like. The method comprises the following steps: firstly, evenly mixing nanometer Al2O3, nanometer SiO2, jute fiber, palm leaf sheath fibers and a powdery air entraining agent, to obtain a mineral and vegetable fiber mixture; then evenly mixing the mineral and vegetable fiber mixture with concrete greening additive, organic matters and cement to obtain an admixture; and finally, mixing the admixture with dry soil, evenly stirring to obtain the frost-resistant habitat base material for the alpine region, and spraying the frost-resistant habitat base material to slopes by utilizing an air compressor. In the habitat base material, pore distribution is finer and more uniform, the fiber reinforcement network develops better, the capability of ecological protective engineering on resisting the frost damage can be effectively enhanced, and the frost-resistant habitat base material for alpine region has significant meaning to the popularization and application of the ecological protection technology in the alpine regions.

Description

technical field [0001] The invention relates to the technical field of ecological protection, in particular to providing an anti-freeze habitat base material used in high-cold regions in ecological protection projects, so as to improve the adaptability and durability of ecological protection projects in high-cold regions without affecting the normal growth of vegetation sex. 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 w...

Problems solved by technology

Due to the long frost period in alpine regions, the freezing and thawing phenomenon caused by surface water will seriously erode the substrate, the change of physical structure and the loss of weight make it difficult for the habitat substrate to provide conditions for the continued growth of vegetation

For example, the ecological protection technology of vegetation concrete has been promoted in a large area in my country. The addition of cement makes it have higher strength and durability. Volume loss rate exceeds 50%

[0004] According to literature reports, some scholars have carried out some exploratory studies, and chose to add external admixtures composed of air-dried Huashan pine needles, fly ash, liquid surfactants, etc. to the habitat substrate, but the antifreeze effect of the habitat substrate is not good not ideal
