- 摘要:
- 现行的细水雾灭火系统技术规范中，要求开式系统的防护区数量不应大于3个,单个防护区容积不宜大于3 000 m3。由于综合管廊的狭长特殊空间结构，这些条文不利于高压细水雾灭火系统应用在管廊中。在南宁市玉洞大道南北侧道路综合管廊设计中，采用了高压细水雾消防系统。设计参考重庆市地方标准及档案行业标准并做出如下优化,取消防护区数量3个的限制；单个防护区的容积按不大于3 000 m3控制；单个分区控制阀的控制面积按120~150 m2控制。优化后的设计方案更符合综合管廊消防的特点，投资更省。
- Abstract:
- According to the current technical specification for water mist fire extinguishing system, the number of open protection zones is no more than 3 and the volume of single protection zone is no more than 3 000 m3 in open type system. However due to the narrow and special spatial structure of the utility tunnel, these requirements are not conductive to the application of high pressure water mist fire extinguishing system in utility tunnel. The high pressure water mist fire extinguishing system was used in the design of the utility tunnel on the South and North side of Yudong Road in Nanning. Based on local standards of Chongqing City and archives industry standards, there are some improvements in the design process: ①canceling limitation of 3 enclosures;②controlling the volume of a single protective area no more than 3 000 m3; ③determining the area of controlled valve in single section as 120-150 m2. The optimized design made investment more economical and it was more in line with the characteristics of fire extinguishing in the utility tunnel.
