초록

본 연구에서는 콘크리트 하수관로의 결함부를 보수하기 위한 자주차의 개발 및 성능평가에 관한 연구를 수행하였다. 비굴착 방식인 자주차를 활용한 하수관로 보수를 위하여 구동 시스템, 보수 유닛 설계 및 보수재료 압송에 관한 성능을 고려하여 자주차를 개발하였다. 개발된 자주차의 성능평가를 하기 위하여 직경 500mm 콘크리트 하수관로에 결함부를 모사하여 보수실험을 수행하였다. 이후, 보수가 완료된 하수관로를 양쪽 끝단과 결함부에 플러그를 삽입하여 고정하고, 물을 주입하여 보수부위에서 누수 여부를 통한 수밀성능을 평가하였다. 누수량은 0.07L/㎡으로 허용 누수량 0.2L/㎡ 이하의 값을 나타내며 우수한 수밀성능을 나타내었다. 따라서 본 연구에서 개발한 자주차는 우수한 보수성능을 나타내는 것으로 판단된다.

In this study, an experiment was conducted on the development and performance of self-propelled vehicles to repair defects in concrete sewage pipes. The self-propelled vehicle for a non-excavation repair for the sewage pipe defects was developed in consideration of the performance of the driving system, the feasibility of the repair unit, and the transportation of repair materials. In order to evaluate the performance of the developed self-propelled vehicle, a repair test was performed by simulating a defect at a connection between the main pipe and extruded one. The main sewage pipe was meade of concrete and its diameter was 500mm. Thereafter, watertightness performance was evaluated on the leakage at the repaired part. For watertightness performance, both ends of concrete sewage pipe and connected one was inserted by plugs, and then water was injected. The amount of leakage water measurement was 0.07L/㎡, indicating a value less than 0.2L/㎡ of the allowable leakage amount. Therefore, test results indicated that the self-propelled vehicle developed in this study exhibited excellent maintenance performance for repairing the sewage pipes.
