Abstract:
An ureolytic bacterium was isolated from a soil in Japan. Using the microbial precipitation of carbonate, sands were cemented. This study mainly deals with the injection techniques of a solution composed of microbes and chemical reagents. The downward infiltration of the mixture injected from pipes into sands was recognized from the cemented zones induced by the microbes. It was found that the injection behaviour was influenced by the size of the injection pipe, injection rate, microbial precipitation time of carbonate, etc. The results of injection experiments showed that the technique can be feasible for in-situ soil improvement.
