대도심지의 교통 체증 문제로 발생되는 경제적 손실의 해결방안으로 대심도 지하도로 개발이 국내외적으로 대두되고 있으며, 이 중 일부는 시공성 및 경제성이 뛰어난 복층터널로 계획되고 있다. 그러나 복층터널은 하나의 굴착단면에 중간 슬래브를 설치하여 상 하행선으로 사용하는 특수한 구조로 인해 일반 터널보다 층고가 낮게 설치되어 터널내에서 발생되는 화재사고 및 환기 문제에 대해 비교적 취약하다. 따라서, 복층터널의 방재적 약점을 극복하기 위해서는 복층터널에 최적화된 방재 설비구축 연구가 국내에서도 체계적으로 수행되어야 한다. 본 연구에서는 복층터널 화재 안전성 향상을 위해 화재발생시 초기 화재 진압 및 확산 방지가 가능한 자동모니터 소화설비를 개발하였으며, 차량화재 진압 실험을 통해 성능시험을 수행하였다. 그 결과로부터 30 m 거리의 차량내부화재 및 10 m 거리의 엔진룸 화재에 대해 화재 확산 방지 및 진압 효과를 확인하였다. |

As one of the solutions to deal with economic loss caused by traffic congestion in metropolitan area, a deep underground road has been planned and implemented at home and abroad. The part of them has been pushed ahead with a double-deck scheme which has an advantage in constructability and cost efficiency comparing to traditional road tunnel. However, the double-deck tunnel has a lower floor height than the general road tunnel due to the special structure used as the upper and lower lines by installing the middle slab on one excavation section. Therefore, it is relatively weak against fire accidents and ventilation problems occurring in tunnels. Thus study to develop the life safety system optimized to a double-deck tunnel has been systematically carried out in order to overcome their weak point. In this study, automatic monitoring fire extinguisher (AMFE) is developed to suppress a fire and prevent its spread at early stage of tunnel fire, conducting the performance test through vehicle fire tests as verification. The tests were conducted with AMFE being 30 m apart from the vehicle and 10 m apart from engine room. As a results, it was confirmed that AMFE enables to suppress a fire and prevent its spread in both cases. |
