Abstract

도관 결함부의 부분라이너 부착공법 및 그 장치가 다음과 같이 개시된다. C.C.TV 카메라 및 모니터를 이용하여 도관내의 결함부를 육안으로 탐지하고 그 결함부까지의 거리로 이동시키고, 상기 부분라이너 부착장치의 팽창튜브에 에어호스를 이용하여 공기를 주입시킴으로써 팽창튜브를 팽창시키고 부분라이너를 주변온도를 이용하여 경화시킴으로써 상기 결함부에 부착시키며, 상기 부분라이너의 경화시간 경과후 상기 팽창튜브로부터 공기를 배출시켜 그 팽창튜브를 수축시킨 후, 상기 부분라이너 부착장치를 이동시켜 도관내로부터 제거시키므로써 작업이 완료된다. 이를 위해 도관내에서의 이동수단과, 그 이동수단의 일단에 부착되는 가요성 팽창튜브와, 그 팽창튜브를 팽창시키고 수축시키기 위하여 그 팽창튜브에 연결된 에어호스를 지니는 에어라인을 구비하는 도관결함부의 부분라이너 부착장치가 제공된다. 이에 따라, 원형을 유지하는 도관의 결함부를 보수함에 있어, 지면을 굴착함이 없이 도관의 내부에서 보강용 부분라이너튜브를 그 결함부에 간단하고도 쉽게 부착할 수 있다.A partial liner attachment method and a device thereof are disclosed as follows. Visually detect the defects in the conduit using CCTV cameras and monitors, move them to the distance to the defects, and inflate the expansion tube by injecting air into the expansion tube of the partial liner attachment device using an air hose. The liner is hardened by using an ambient temperature to adhere to the defect, and after the curing time of the partial liner is discharged from the expansion tube to shrink the expansion tube, the partial liner attachment device is moved to move in the conduit. The work is completed by removing it from the. To this end, a conduit defect comprising an airline having a movement means in the conduit, a flexible expansion tube attached to one end of the movement means, and an air hose connected to the expansion tube to expand and contract the expansion tube. A partial liner attachment device is provided. Accordingly, in repairing the defect portion of the conduit holding the circular shape, it is possible to simply and easily attach the reinforcing partial liner tube to the defect portion in the conduit without digging the ground.
