Claims (1)
점성토지반(粘性土地盤)하에 사질토지반이 개재(介在)되는 지반에 있어서, 상기 점성토지반중을 하단에 굴삭수단을 가진 롯드에 의해 천공추진(穿空推進)함과 동시에 지반 개량용 약액의 주입작업을 동시에 진행시키고, 사질토지반으로 이행하는 곳에 상기 약액의 주입을 멈춘 상태로 이 지반의 소정위치까지 천공 추진시킨 후, 약액을 저압으로 주입해 가면서 롯드를 인출, 조작하는 것을 특징으로 하는 약액 주입 공법(藥液注入工法).In the ground where sandy soils are interposed under viscous soils, the drilling of bores is carried out by the rod having excavating means at the bottom of the viscous soils, and at the same time, the injection of chemical solution for improvement of the soils. At the same time, the injection of the chemical liquid is carried out to the predetermined position of the ground while the injection of the chemical liquid is stopped at the transition to the sandy soil, and the chemical liquid is injected at low pressure while drawing and operating the rod.
