灭火系统是综合管廊安全运营的基本保障。深圳地铁某共建综合管廊工程入廊市政管线包括电力、通信、给水、再生水等类别,而其中有中高压电力电缆的舱室火灾危险性最大。根据共建综合管廊的运营特点,深圳地铁共建综合管廊消防灭火系统采用自动与手动灭火相结合的方式,选用超细干粉自动灭火系统和手提灭火器,文章分别对其设计进行阐述。
The fire-extinguishing system is the basic guarantee for the safe operation of the utility tunnel.The municipal pipelines entering the utility tunnel of joint construction project of Shenzhen metro include power cables,communication cables,water supply pipes,recycled water pipes and other categories;among which,the compartment with medium and high voltage power cables holds the highest fire risk.According to the operation characteristics of the joint construction utility tunnel,the fire-extinguishing system of the joint construction utility tunnel of Shenzhen metro adopts a combination of automatic and manual fire extinguishers.The ultra-fine dry powder automatic fire-extinguishing system and portable fire extinguisher have been selected,and their design is described respectively.
