Ruins soil in-situ excitation reinforcement method based on MICP
The invention provides a ruin soil in-situ excitation reinforcement method based on MICP, and belongs to the technical field of geotechnical engineering. The method comprises the following steps: (1) adding a bacterial culture solution into a to-be-reinforced area of the earthen ruin, and standing; (2) adding a cementing liquid into the to-be-reinforced area of the ruin soil after standing in the step (1), and reinforcing; the bacterial culture solution comprises the following components: a yeast extract, nickel chloride hexahydrate and ammonium chloride; the cementing liquid comprises the following components: urea, calcium chloride and a yeast extract. According to the method, the native bacteria of the ruin soil are re-cultured in the soil body, the earthen ruin is repaired and reinforced through the metabolic activity of the in-situ bacteria, the strength and weather resistance of the ruin soil are improved, no foreign bacteria are introduced, and other influences on the ecology are not caused.
本发明提供了一种基于MICP的遗址土原位激发加固方法，属于岩土工程技术领域。本发明的方法，包括如下步骤：(1)将细菌培养液添加至土遗址待加固区域，静置；(2)将胶结液添加至步骤(1)静置后的遗址土待加固区域，加固；所述细菌培养液包括如下组分：酵母提取物、六水氯化镍、氯化铵；所述胶结液包括如下组分：尿素、氯化钙、酵母提取物。本发明利用遗址土的原生细菌，在土体内重新培养，通过原位细菌的代谢活动修复、加固土遗址，提高了遗址土的强度和抗风化性能，且没有引入外来细菌，不会对生态造成其他影响。
