| titleOfInvention | Microorganism induced mineralization reinforcement soil body grouting method introducing urease inhibitor |
| abstract | The invention belongs to the technical field of soil body reinforcement, and discloses a microorganism induced mineralization reinforced soil body grouting method with urease inhibitor introduced. Fully mixing urease-producing bacterial liquid with a soil body to be solidified, and standing until the attachment of the urease-producing bacterial liquid on the particle surface of the soil body to be solidified is completed; then, adding the urease inhibitor into the cementing liquid, fully stirring and dissolving, and grouting; the cementing liquid is a mixed liquid of calcium chloride and urea, the urease inhibitor is a competitive inhibitor of urease, and the mixing amount of the urease inhibitor is far lower than the mass content of urea in the cementing liquid, so that the final result of urea hydrolysis is not influenced. The invention uses the competitive inhibitor of urease and urea to compete for the active site of urease, and reduces the efficiency of urea decomposition by urease, thereby effectively delaying the hydrolysis process of urea in the initial stage of grouting, reducing the local blockage in the initial stage of grouting, simplifying the grouting process and ensuring uniform curing effect. |
