Method Of Echo-Ground Reinforcement Using Bacteria Enzyme Induced calcium carbonate Precipitation
An eco-friendly ground reinforcement method of the present invention using the precipitation of calcium carbonate by enzyme derived from microorganisms can use urea decomposition enzymes derived from highly active microorganisms without using non-indigenous microorganisms to replace synthetic resins and cement without disturbing the soil′s microbial ecosystem, thereby reinforcing slopes and grounds in an environmentally friendly manner. Further, the eco-friendly ground reinforcement method of the present invention can use an extract containing a high concentration of urea decomposition enzymes that are smaller than microorganisms and water-soluble, thereby being advantageous in penetration thereof through pores in the soil, and enables the extract to deeply penetrate through slopes including fine grain soil or soft mixed soil grounds, thereby being capable of solidifying the ground through the precipitation of calcium carbonate. In particular, when applied to the slopes including the fine grain soil or the mixed soil grounds, the eco-friendly ground reinforcement method can reinforce the ground by increasing its compressive strength and ductility while reducing permeability. The method comprises a step of precipitating calcium carbonate by spraying a urea-calcium chloride-mixed solution on the mixed soil ground.
본 발명은 환경오염의 우려가 있는 비 토착 미생물을 사용하지 않으면서도 활성도가 높은 미생물 유래 요소분해효소를 사용하므로 토양 미생물 생태계의 교란 없이 합성수지 및 시멘트를 대체하여 경사지 또는 지반을 친환경적으로 보강할 수 있는 장점이 있다. 또한 본 발명은 미생물에 대비하여 크기가 작고 수용성인 요소분해효소를 고농도로 포함하는 추출액을 사용하므로 토양공극을 통한 침투가 유리하며 세립토가 포함된 경사지 또는 연약 혼합토 지반에서도 지반 깊숙이 침투하여 탄산칼슘 침전반응을 통한 지반 고결이 가능한 장점이 있다. 특히, 상기 세립토가 포함된 경사지 또는 혼합토 지반에 적용되면 압축강도 및 연성은 증가시키는 반면 투수도는 감소시켜 지반을 보강하는 효과가 있다.
