Method for solidifying fractures of earthen ruins through microbial grouting
The invention discloses a method for solidifying fractures of earthen ruins through microbial grouting. A mode that the peripheries of the fractures are coated with sealing cement gum, liquid is conveyed through a peristaltic pump and grouting is distributed is adopted, so that the influence of a side wall effect in the grouting process is reduced, the problem that seepage of a solution in the fractured earthen ruins is too slow is solved, materials are easy to obtain, operation is easy, the compatibility between calcium carbonate generated by mineralization reaction and original components of the earthen ruins is high, the effect that microorganisms gradually solidify the earthen ruins fractures is obvious, and a new thought is provided for solidifying the earthen ruins fractures through an MICP technology.
一种微生物注浆固化土遗址裂隙的方法，采用裂隙周围封涂密封胶泥、蠕动泵运输液体和分布灌浆的方式，减少了注浆过程中边壁效应的影响和溶液在裂隙土遗址试样中渗流过慢的问题，材料易得，操作简单，矿化反应生成的碳酸钙与土遗址原有成分相容性较强，微生物逐级固化土遗址裂隙效果明显，为MICP技术固化土遗址裂隙提供了新思路。
