Abstract
The present invention discloses a microbially induced carbonate precipitation (MICP)-based vertical barrier, and a preparation method thereof, wherein a raw material of the vertical barrier includes in-situ soil, Ca-bentonite, a bacteria-containing culture medium, and a cementing solution. The bacteria-containing culture medium comprises flocculent ureolytic bacteria flora. The proportions of dry the Ca-bentonite to in-situ soil, the bacterial-containing culture medium to the cementing solution, and the cementing solution to the Ca-bentonite are specified to be 1:2, (2˜5):1, and (1˜2.5):10, respectively, to ensure optimal performance. The present invention addresses challenges related to the insufficient impermeability of Ca-bentonite-based barriers in the application of vertical barrier, and aims to reduce both the cost and carbon emissions associated with their construction.
