机场塔台无高位消防水箱之增强措施探讨

Discussion about strengthening measures for an airport tower without elevated fire tank

机场塔台顶层指挥明室因空管工艺需求,屋顶采用轻钢结构,受结构承载力和限高的要求,塔台无法设置高位消防水箱。通过火灾场景、烟气流动模拟和人员安全疏散分析,提出消防强化措施,主要包括采用稳高压消防系统、两路供水、两路供电、采用快速响应喷头、优化管材选择、采用物联网消防设备和配置空气呼吸机等。模拟结果显示,在发生火灾区域的自动灭火系统和排烟系统有效的情况下,清晰高度处的人员可用疏散时间较长,该消防方案能达到防止火灾大规模蔓延和保障建筑内人员安全的消防设计安全目标。

Due to the requirements of the tower command dim room, the roof adopts light steel structure. The tower cannot set elevated fire tank restricted by bearing capacity of structure and building height. Analyzing fire scene, fire smoke flow and personnel safe evacuation, strengthening measures were proposed, such as fire water supply system of stable-high pressure, two way of water supply,dual power supply, using fast response sprinkler optimizing the selection of pipes, firefighting equipment with internet of things, and deploying air ventilator. Evacuation time was long in the event that the automatic fire extinguishing system and smoke exhaust system in the fire area were effective, achieving the design safety goal which can prevent fire from spreading in large scale and guarantee the personnel safety in the building.
