smoke control area

Maintains that the smoke control system should be simplified, public zone should be divided into two smoke control zones, and that it can save space, reduce construction cost and improve reliability of the system to take close smoke prevention as the main way, assisted by way of smoke exhaustion through the walkway in equipment and management rooms.

根据地铁车站的实际情况,结合设计中遇到的实际问题对地铁车站的防排烟系统设计进行了探讨,认为在地铁车站设计中应尽量简化防排烟系统,车站公共区可以划分为站厅、站台两个防烟分区,设备及管理用房采用以密闭防烟为主、走道排烟为辅的方式可以节省空间,降低地铁造价,提高系统的可靠性。
