Abstract

The invention relates to a material for modifying side slope soil and a preparation method thereof. The material specifically comprises polyacrylamide, polyacrylate emulsion, bentonite, kaoline, desulfurized gypsum, fiber, water and the like in a certain weight ratio. By adopting the material, the water and soil conservation of the side slope soil can be effectively enhanced, and the side slope erosion is prevented or slowed down. The material has a good application prospect in the aspect of side slope protection.

Description

technical field [0001] The invention relates to a side slope soil modification material capable of preventing water and soil loss and meeting the needs of plant growth, especially in arid and semi-arid areas, which can effectively improve the water and soil conservation of side slope soil and prevent or slow down side slope erosion. Background technique [0002] Slope ecological protection technology is based on the basic principles of ecological engineering, engineering mechanics, botany, hydraulics and other disciplines. It uses active vegetation materials and other engineering materials to build an ecologically functional slope protection system on the slope. Support, self-organization, and self-repair functions to achieve anti-erosion, anti-sliding and ecological restoration of slopes, so as to reduce soil erosion, maintain ecological diversity and ecological balance, and beautify the environment. In recent years, my country's slope ecological protection technology has b...
