Rainwater washing prevention method for granite residual soil side slope of transmission tower

The invention belongs to the field of soil slope prevention and treatment and foundation reinforcement, and particularly relates to a rain wash prevention method for a granite residual soil slope of a transmission tower. The method comprises the steps that microorganisms generating urease are subjected to fermentation culture, bacterium liquid obtained after fermentation culture is evenly sprayed to the surface layer of a soil body, then nutritive salt is sprayed, the ratio of the spraying volume of the bacterium liquid obtained after fermentation culture to the volume of the soil body to be reinforced is (0.4-0.6): 1, and the OD600 of the bacterium liquid is 2.4-2.6. Aiming at the granite residual soil slope of the transmission tower in the south, a self-source microbiological treatment method is adopted for protection and treatment of rain wash, microorganisms generating urease are cultured through fermentation, bacterial liquid obtained after fermentation culture is evenly sprayed on the surface layer of a
