Abstract

The concrete lining inspection by inspector after traffic control poses various problems such as congestion caused by traffic control and social loss costs resulting from it, and risks of traffic accidents and safety accidents for inspectors et al. To solve the problems, the concrete lining inspection has been carried out using automatic inspection equipment and image analysis that can be objectively and quantitatively investigated in overseas. In this study, to solve the problems of concrete lining inspection by inspector and to review improvement plan for inspection, inspection was carried out using automatic inspection equipment for ○○ tunnel that precision safety diagnosis has been conducted in 2019. Analysis was carried out for both inspection results. Automatic inspection equipment investigated defects in concrete lining such as cracks more accurately than precision safety diagnosis.

교통통제 후 인력점검 방식으로 시행되고 있는 콘크리트 라이닝 점검방식은 교통통제에 의한 정체유발 및 이로 인한 사회적 손실비용이 발생되며, 교통사고 및 점검자 안전사고 위험 등 다양한 문제점을 내포하고 있다. 이러한 문제점을 해결하기 위해 해외에서는 객관적이고 정량적 조사가 가능한 자동점검 장비 및 영상분석을 통한 콘크리트 라이닝 점검을 수행하고 있다. 본 연구에서는 인력점검 방식으로 시행되고 있는 콘크리트 라이닝 점검 및 진단방식의 문제점 해결 및 개선방안 검토를 위하여, 2019년 정밀안전진단을 시행한 ○○터널 상 ‧ 하행선에 대하여 국내에 도입된 터널 자동점검진단 장비를 이용한 점검 시행 후 정밀안전진단 조사 결과와 비교 분석하였다. 터널 자동점검진단 장비를 이용한 점검은 정밀안전진단 보다 정확하게 균열 등 콘크리트 라이닝에 발생한 결함을 조사할 수 있는 것으로 나타났다.
