Abstract
본 발명은 지반강화공법 및 지반강화용 주입장치에 관한 것으로서, 본 공법은 핵노즐부와 포위노즐부로 각각 이루어진 측방분사용 상부이중노즐과 하부이중노즐을 갖는 삼중관주입장치를 이용한 지반강화공법에 있어서, 상부이중노즐의 핵노즐부를 통해 청수를 분사하고 포위노즐부를 통해 공기를 분사하여 상기 주입장치를 굴진하강시키는 단계와, 상부이중노즐의 핵노즐부를 통해 청수를 분사하고 포위노즐부를 통해 공기를 분사하는 동시에, 하부이중노즐의 핵노즐부를 통해 경화제를 분사하고 포위노즐부를 통해 공기를 분사하며 상기 주입장치를 상승시키는 단계를 포함하는 것을 특징으로 한다. 이에 의해 비교적 침투성이 낮은 예를 들어 점토성의 지반인 경우에도 효과적으로 확공하여 충분한 경화층을 형성할 수 있게 된다는 효과가 제공된다.The present invention relates to a ground strengthening method and a ground strengthening injection device. Injecting fresh water through the nuclear nozzle portion of the upper double nozzle and injecting air through the surrounding nozzle portion to drive down the injection device, and spraying fresh water through the nuclear nozzle portion of the upper double nozzle and through the air surrounding the nozzle portion And simultaneously spraying the curing agent through the nuclear nozzle portion of the lower double nozzle, spraying the air through the surrounding nozzle portion, and raising the injection device. This provides an effect of being able to effectively expand and form a sufficient hardened layer even in the case of clay ground having a relatively low permeability, for example.
