| description | The present invention relates to a mold for preparing a silt soil sample based on microbial grouting. The mold comprises two templates that are in detachable connection; wherein each template comprises a bottom plate, an inner curved plate and an outer curved plate, a plurality of first circular holes are arranged on sidewall of the inner curved plate, and a plurality of second circular holes arearranged in the bottom plate, and a steel wire mesh is arranged on inner surface of the inner curved plate; a filter unit is disposed in an enclosed space on the inner curved plate above the bottom plate. The invention also provides a method for preparing the silt soil sample based on microbial grouting, the method comprises following steps: selecting a mold; culturing microorganism; measuring urease activity; putting the soil into the mold; and injecting microbial liquid and a nutrient solution along the periphery. The mold and method can be applied to silt soil with small permeability coefficient, passes the microbi |
