Method for reinforcing soil strength by utilizing microorganisms to induce calcium carbonate deposition
The invention provides a method for reinforcing soil strength by utilizing microorganisms to induce calcium carbonate deposition, according to the method, double rounds of induction liquid injection are carried out in the curing and reinforcing process, the induction liquid contains urea, and in the reinforcing and curing process, urea provides nutrition for microorganism breeding and is a substrate for inducing generation of calcium carbonate at the same time; the induction liquid is injected twice, so that a new nitrogen source and a new substrate can be supplemented after calcium production in the first round is relatively complete, the calcium production efficiency is improved, and the soil reinforcement effect is improved.
本申请提供一种利用微生物诱导碳酸钙沉积加固土体强度的方法，该方法在养护加固过程中进行双轮诱导液注入，诱导液的成分为尿素，在加固养护的过程中，尿素为微生物繁殖提供营养，同时又是诱导产生碳酸钙的底物，双轮注入诱导液可以在第一轮产钙较为完全后补充新的氮源与底物，以此提高产钙效率，从而提高土体加固效果。
