Steel pipe simultaneous injection grouting method for tunnel construction
The present invention is to provide a steel pipe simultaneous injection grouting method that allows grout material to quickly and uniformly penetrate into the surrounding ground. The present invention relates to a steel pipe simultaneous injection grouting method for tunnel construction, which comprises the steps of: a) processing a steel pipe (10) and inserting a plurality of packers (40) and a plurality of injection pipes into the steel pipe (10); b) forming a drill hole (1) by drilling the ground; c) inserting the steel pipe (10) into the drill hole (1); d) caulking the entrance of the drill hole (1); and e) simultaneously injecting quick setting grout material into the plurality of injection pipes.
본 발명은, 터널 시공을 위한 강관 동시주입 그라우팅 공법에 있어서, 가) 강관(10)을 가공하고, 강관(10) 내부에 복수 개의 패커(40) 및 복수 개의 주입관을 삽입하는 단계; 나) 지반을 천공하여 천공홀(1)을 형성하는 단계; 다) 상기 천공홀(1) 내부에 강관(10)을 삽입하는 단계; 라) 상기 천공홀(1) 입구를 코킹하는 단계; 마) 상기 복수 개의 주입관에, 급결 그라우트재를 동시에 주입하는 단계를 포함하는 터널 시공을 위한 강관 동시주입 그라우팅 공법에 관한 것이다.
