Microorganism repairing agent for repairing rock cracks and preparation method of microorganism repairing agent
The invention discloses a microorganism repairing agent for repairing rock cracks and a preparation method of the microorganism repairing agent. The microorganism repairing agent is prepared from thefollowing raw materials of: bacillus pasteurii and a cementing material, the cementing material is prepared from the following raw materials in parts by weight: 17-35 parts of urea, 32-64 parts of calcium chloride, 10-20 parts of nutrient broth, 1.5-2.5 parts of NaHCO3 and 9-12 parts of NH4Cl; the OD600 value of the bacillus pasteurii in the repairing agent is 0.6-1.2. The microbial remediation agent provided by the invention has the advantages of small size, low viscosity, high permeability, environmental friendliness and the like, and can quickly enter narrow rock cracks to fill and seal thecracks so as to solve the problem of rock crack leakage; the product of microbial mineralization is mainly calcite type calcium carbonate; the product has good stability and durability and is good incompatibility with a matrix material; the method that microorganisms are adopted to induce calcium carbonate precipitation is an eco-friendly technology and has the advantage of being green and environmentally friendly.
本发明公开了一种修复岩石裂隙的微生物修复剂及其制备方法，其原料包括巴氏芽孢杆菌和胶结材料；所述胶结材料包括如下重量份数的原料：尿素17~35份、氯化钙32~64份、营养肉汤10~20份、NaHCO31.5~2.5份和NH4Cl 9~12份；所述修复剂中巴氏芽孢杆菌的OD600值为0.6~1.2。本发明提供的微生物修复剂具有体积小、粘性低、渗透性高、绿色环保等特点，能快速的进入到狭窄的岩石裂缝中，进而对裂缝进行填充与封闭，以解决岩石裂隙渗漏的问题。其次微生物矿化的产物主要为方解石型碳酸钙，产物具有良好的稳定性和耐久性与基体材料相容性好，采用微生物诱导碳酸钙沉淀是一种生态友好型技术，具有绿色环保的优点。
