MULTI-PACKER TUBLAR MEMBER CHEMICAL INJECTION APPARATUS AND CHEMICAL INJECTION METHOD USING THE SAME
Since a multi-packer for grouting that enables not only lateral injection of chemical solution but also downward injection is required, by providing a multi-packer characterized in that packers disposed above and below one or more chemical liquid injection units having openings through which chemical liquid is discharged are independently expandable and contractible, for n, the number of packers, provided is a technique that enables 2^(n) free packer operations.
약액의 측방주입 뿐아니라 하방주입도 가능하게 하는 그라우팅용 멀티패커가 요망되므로, 약액이 토출되는 개구를 가지는 1 이상의 약액주입부의 상측 및 하측에 배치된 패커들이 서로 독립적으로 팽창 수축 가능하도록 이루어짐을 특징으로 하는, 멀티패커를 제공하여, 패커의 개수 n에 대해, 2^(n) 가지의 자유로운 패커 동작을 가능하게 하는 기술을 제공한다.
