摘要
综合管廊是保障城市运行的重要基础设施和"生命线",为了避免管廊发生管道爆炸火灾等不安全事故,本文以管廊内火灾事故等不安全因素地识别及早期预警为重点,对管廊内部环境进行分析,同时针对目前管廊存在的问题,分析了现有火灾预警系统的不足,将分布式光纤测温技术应用在地下管廊火灾危险识别,以便较早地发现管廊安全隐患,对管廊火灾事故及时预警.
Comprehensive utility tunnel is an important infrastructure of city running and lifeline.In order to avoid the pipe gallery pipe explosion unsafe accidents such as fire based on the pipe rack inside the unsafe factors such as fire accident identification and early warning,analysis of pipe gallery internal environment.At the same time, aiming at the problems existing in the pipe gallery,the shortage of the existing fire warning system are analyzed,according to the principle of distributed optical fiber temperature measurement technology and its application on the pipe rack,the research content to some extent,can be found earlier utility tunnel safe hidden trouble,do make early prevention of utility tunnel fire accidents timely warning.
