Abstract:
GB 51309—2018 has new requirements on the storage battery placement position of fire emergency lighting and evacuation indication system in urban rail transit line interval. The newlybuilt line shall be constructed according to this standard. The design scheme of interval fire emergency lighting and evacuation indication system meeting the requirements of GB 51309—2018 and the corresponding battery placement scheme, as well as their advantages and disadvantages are analyzed. The design scheme of tunnel fire emergency lighting and evacuation indication system and the corresponding battery placement scheme of Suzhou Rail Transit Line S1 and Line 6, as well as metro lines in other cities in China are introduced. A battery maintenance strategy based on different battery placement schemes is proposed.
