Abstract

Clogging phenomenon is one of the important problems in deteriorated tunnels, and it caused inhibition of drainage system by long-term behavior. Clogging phenomenon is mainly composed of CaCO3 in the form calcite. Calcite is generally created by the reaction of Ca(OH)2 with CO2 emitted from vehicles. The structure of deteriorated tunnels was simulated and the setting of outflow from drainage pipe was observed in this study. The test was experienced by changing the slope of drainage system because existing drainage system was pracitced almost below 5°. As a result, in case of drainage system’s slope is 2°, Quantum Stick has an effect for prohibiting scale in drainage system, but magnetic treatment was not effective. As a result, in case of drainage system’s slope is 5°, both technologies were effective for prohibiting scale in drainage system, but Quantum Stick was especially more effective than magnetic treatment.

노후화된 터널에서 배수공의 막힘현상은 중요한 문제점으로 대두되며, 장기적으로는 배수시스템에 폐색현상을 일으킨다. 배수시스템에서의 침전물 방지를 위한 요소기술 검증을 위해 본 연구에서는 도로터널의 토사층 및 라이닝을 모사하여 배수공의 유출수에서의 침전현상을 살펴보았다. 또한 기존의 배수공들은 대부분 5° 이하로 설치되었기 때문에 배수공의 기울기를 변화시켜가며 시험하였다. 배수공의 기울기를 2°로 한 경우에는 퀀텀스틱은 스케일의 생성을 방지하는 데 효과가 있었으나 자화장치는 효과가 없는 것으로 나타났다. 배수공의 기울기를 5°로 한 경우에는 퀀텀스틱과 자화장치 모두 배수공내 스케일의 생성을 방지하는 데 효과가 있었으나, 특히 퀀텀스틱이 자화장치보다 더욱 효과가 있는 것으로 나타났다.
