Abstract

진동과 소음공해 발생이 적은 매립말뚝공법에 탁월한 지반 강화효과를 겸비시키기 위하여 외주에 노즐(8)이 다수 장착된 피씨말뚝을 미리 뚫려진 말뚝공(6)에 매설하여 놓고, 상기한 피씨말뚝(2)의 내부 중공(10)을 통해 그라우팅재를 주입하거나 또는 유체압에 의해 팽창되는 패커(12)를 삽입하여 일정의 공간(14)이 형성되게 한 후에, 패커(12)를 관통하여 설치된 관체(16)로 그라우팅재를 주입시켜서 피씨말뚝(2)이 매설된 부근의 지반을 그라우팅처리하여 지반을 안정화시키는 지반 강화 매설말뚝공법.In order to combine the excellent ground reinforcement effect with the landfill pile method with less vibration and noise pollution, the PC pile with a large number of nozzles 8 mounted on the outer periphery is buried in the pile hole 6 previously drilled. After injecting grouting material through the inner hollow 10 of 2) or inserting the packer 12 that is expanded by fluid pressure to form a predetermined space 14, the tubular body installed through the packer 12. (16) Ground reinforcement laying method for stabilizing the ground by injecting grouting material to grind the ground in the vicinity of the PC pile (2) buried.
