【摘要】：向土体中灌注营养液可生成新的化合物,由此降低土体的渗透系数,以达到防渗封堵的效果.在实验室中向粉土和回填土中灌注马铃薯液,土壤的渗透性均有显著降低:粉土的渗透系数降低了95%,回填土的渗透系数降低了88%.试验在低于20℃的环境下进行,但微生物仍能保持足够的活性,可达到封堵效果.向出现渗漏的地下车库墙外回填土内灌注马铃薯液,回填土的渗透系数降低了95%.现场试验气温达到30℃,更有利于微生物的生长和繁殖,封堵时间短,效果更好.
[Abstract]:A new compound can be formed by filling the nutrient solution into the soil, thus reducing the permeability coefficient of the soil, so as to achieve the effect of anti-seepage and plugging. The permeation coefficient of silt soil and backfill soil decreased by 95% and 88% respectively when potato solution was infused into silt and backfill in laboratory. The experiment was carried out under the condition of 20 鈩，
