摘要
介绍深圳地铁4号线某地下岛式车站防排烟系统设计。该站厅层为地面层,设计采用自然排烟;站台、设备层采用机械排烟设计。站台公共区域排烟系统模式分为正常夏季工况、正常冬季工况、普通火灾模式一和普通火灾模式二。介绍区间隧道、车站内公共区域、设备管理用房通风系统设置,介绍设备选型、参数等。建议车站站台防排烟系统设计时充分考虑排烟气流组织方式,使站台形成气流场,避免出现排烟死角。
A smoke control system design of Shenzhen Metro Line 4 with an underground island platform station was introduced.The station hall using natural ventilation was the ground floor,while platform and mechanical floor using mechanical smoke exhaust.Exhaust system models of platform public areas could be divided into normal summer working condition,normal winter working condition,ordinary fire mode Ⅰ and ordinary fire mode Ⅱ.The ventilation system settings,equipment selection and parameters of internal tunnel,public areas of station and equipment management room were presented.The distribution mode of exhaust air should be fully considered in the smoke control system design of platform in order to form airflow field in platform and avoid smoke corner.
