  • Protection method against rain erosion for soil slope improved by phosphogypsum and microbe
    Patent number: 11299865
    Abstract: The present invention provides a method for protecting a soil slope from rain erosion by improving with phosphogypsum and a microbe. The method includes: (1) placing Bacillus pasteurii in a culture medium to prepare a microbial solution, and mixing urea, calcium chloride and water to prepare a cementing solution; (2) mixing a mixture, the microbial solution and water well, and adding the cementing solution and water to prepare an improving mixture slurry; and (3) spraying the improving mixture slurry to a face of the slope twice by wet spraying, mixing the improving mixture slurry with grass seeds well, spraying to the face of the slope once, covering with a non-woven fabric by tying and fixing to the slope, and watering every day.
