| titleOfInvention | Combined repairing method for multi-scale fracture of rock mass based on microbial mineralization |
| abstract | The invention provides a combined repairing method of a rock mass multi-scale fracture based on microbial mineralization, which comprises the following steps: placing a grouting pipe in the surface main crack at the millimeter level or more than the centimeter level; uniformly injecting the mixed slurry A, the mixed slurry B and the microorganism mixed solution into the deep cracks by using grouting equipment in sequence; the mixed slurry A is obtained by uniformly mixing and stirring in-situ rock sand, magnesite powder, a urea solution and a urease solution in parts by weight; the mixed slurry B is obtained by uniformly mixing and stirring in-situ rock sand, limestone powder, a urea solution and a bacillus pasteurianus bacterial solution; the microorganism mixed solution is obtained by uniformly mixing and stirring limestone, a urea solution and a bacterial solution; the combined repairing method of the rock mass multi-scale fracture based on the microbial mineralization can repair the multi-scale fracture at high pressure, high efficiency and high repairing rate, and has the advantages of convenient acquisition of repairing materials and good compatibility and weather resistance. |
