Abstract

SSG (self-healing smart grouting) method, which is developed recently, has the characteristics such as an improvement of durability and waterproofing, prevention of leaching and pollution. In this study, we performed several tests such as gel-time measurement, uniaxial compression test, permeability test, fish poison test and chemical resistance test to compare the engineering properties of SSG with the other chemical grouting method (LW, SGR). As results of tests, the SSG method has low possibility of groundwater and ground pollution caused by leaching, furthermore, it has advantages like long/short term waterproofing, strength and durability. Therefore the SSG method can be applicable in the fields as an alternative of existing chemical grouting methods with problems.

최근 개발된 자기치유 그라우팅(SSG, self-healing smart grouting)공법은 지반의 내구성 및 차수성의 향상, 용탈 및 환경오염 방지 등의 특성을 가지고 있다. 이 연구는 SSG공법의 공학적 특성을 규명한 것으로써 기존 약액주입(LW, SGR)공법과의 공학적 특성을 비교하기 위해 겔타임 측정, 일축압축강도 시험, 투수 시험, 어독성 시험, 내화학성 시험을 수행하였다. 연구결과, SSG공법은 장 단기 차수성능 유지, 강도 발현, 내구성 확보에 유리하고 용탈에 의한 지하수 및 지반의 오염 가능성이 낮은 것으로 나타났다. 이를 통해 SSG공법은 기존 약액주입공법의 문제점들을 최소화할 수 있는 대체 공법으로 현장에 적용이 가능할 것으로 판단된다.
