Abstract

Visibility is very poor in tunnel fire because of confined space where the fire may easily lead to the mass casuality incident because of fast smoke spread. In this test, air curtain and the fan were installed at rescue station in a bid to make use of rescue station in safe way during the train fire in undersea tunnel and a full-scale fire test was conducted to identify the applicability of air curtain system. Air curtain system was installed at a real rescue station and the test was continued for 2 minutes till heptane which was used as fire source was completely burned out. When air curtain was working, difference in temperature between inside and outside the platform was 160°C and carbon monoxide measured inside the platform was less than the case of no air curtain system by 160 ppm. Thus a full-scale fire test demonstrated that the air curtain system installed at rescue station in undersea tunnel was able to effectively block the heat and smoke generated from the fire.

터널 화재는 밀폐된 공간에서 발생하기 때문에 시야 확보가 매우 어려우며, 빠른 속도로 연기가 차오르기 때문에 대형재난사고로 이어질 수 있다. 본 연구에서는 해저터널 열차 화재 시 구난역을 안전하게 사용하기 위하여 에어커튼 및 가압송풍기를 구난역 플랫폼에 설치하고 실물화재실험을 통하여 에어커튼 시스템의 적용성을 확인하였다. 실제 규모의 구난역에 에어커튼 시스템을 설치하였으며, 화원으로 사용한 액체 햅탄이 전소될 때까지 약 2분 동안 실험을 진행하였다. 에어커튼 시스템이 작동한 경우에는 구난역 플랫폼의 온도와 외부의 온도는 약 160°C 차이가 발생하였으며, 에어커튼 시스템이 작동한 경우에 구난역 플랫폼 내부의 일산화탄소는 작동하지 않은 경우의 구난역 플랫폼 내부와 비교하여 약 160 ppm 적게 일산화탄소가 측정되었다. 따라서 본 실물화재 실험을 통하여 해저터널 구난역 에어커튼 시스템이 화재로부터 발생한 열기와 유독가스를 차단할 수 있음을 확인하였다.
