Fire escape during for operation.
(3) auxiliary facility is complete, ensure that in emergency circumstances safety evacuation.
(3) height of vertical shaft meets《The safe ＞ of International Union of Railways (UIC) code 779-9/R ＜ railway tunnel (2003 editions)》
Standard, rectangle or circular cross section are beneficial to construction and meet stair arrangement requirement.Stairway width meets《Metro design code》
(GB50157) requirement.
(4) protective door compared with general fire resistant doorsets, in addition to possessing fire resisting, decay resistance, is also equipped with resisting train piston
The effect of blast.
(5) jet blower is prevented from smog and enters emergency exit, while ensureing the resh air requirement required for personnel's breathing；Penetrate
Three kinds of control models of flow fan ensure that in case of emergency the very first time starts blower fan.
(6), while personnel's evacuation safety being ensured using the structural system and ventilation Smoke prevention technology, it is greatly saved tunnel
Build and operation maintenance cost.
