Grouting simultaneous injection pipe
The present invention relates to a grooved steel pipe for simultaneous injection of grout, which is implemented to minimize inference with support materials by removing a part of the entrance of a steel pipe for grout injection after grouting is completed. The simultaneous injection steel pipe includes a circular grouting pipe, a plurality of injection holes perforated at regular intervals along the grouting pipe, a center bolt formed to push an expansion member to be in tight contact with a fixing projection (fixing nipple), a finishing end formed to finish the front end of the grouting pipe, and a pusher support ring installed along the outer circumferential surface of the grouting pipe at a predetermined interval from the rear end of the grouting pipe.
본 발명은 그라우팅을 주입하기 위한 강관의 초입부 일부를 그라우팅 완료 후 제거함으로써 지보재 간섭을 최소화시킬 수 있도록 구현한 홈가공을 구비한 그라우팅 동시주입강관에 대한 것이다.
