Microorganism grouting method capable of improving early-stage calcium carbonate deposit volume
The invention discloses a microorganism grouting method capable of improving an early-stage calcium carbonate deposit volume, which comprises the following steps: (1) a nutritive salt solution is added into a microorganism bacterium liquid to obtain a mixed liquid of bacterium liquid and nutritive salt, and standing is carried out for 0.5-1h; and (2) during grouting, the mixed liquid of bacterium liquid and nutritive salt is blended with a calcium salt solution according to a predetermined proportion. Due to the adoption of a microorganism grouting material, not only is the total output of calcium carbonate sediment effectively improved, but also the early-stage output of the sediment is can be effectively improved, so that important significance is provided for blocking concrete cracks by utilizing a grouting method. Only a lot of calcium carbonate sediment is generated in relatively short time, the concrete cracks can be blocked in relatively short time, and thus grouting amount and times can be reduced.
