| titleOfInvention | Test device and method for reinforcing silt through demoulding microorganism grouting |
| abstract | The invention discloses a test device and a method for reinforcing silt by microbial grouting capable of demoulding, wherein the device consists of a GDS pressure controller, a grout storage device, a reaction device and a filtrate collecting bottle 4. The GDS pressure controller provides pressure to accurately control the grouting speed, so that the slurry is slowly and uniformly injected into the soil sample. The sample preparation barrel in the reaction device is formed by butting two organic glass tubes, so that the sealing property of the device can be ensured, and the complete demoulding can be facilitated. The invention utilizes the microbial mineralization technology to solidify the silt, adopts the method of injecting the bacterial liquid and the cementing liquid step by step, and better avoids the blockage of the grouting opening caused by the direct mixing of the cementing liquid and the bacterial liquid. And meanwhile, the mode of up-up grouting from bottom is adopted, so that grouting liquid can be better uniformly distributed in the soil sample, and the uniformity and integrity of soil sample solidification are ensured. |
