Firefighting design for urban rail transit depot and topside superstructure-Taking the Tian'edang depot project in Suzhou as an example
mplementing topside property development is the optimal mode for the construction of urban rail transit depot,but there are no detailed provisions in the current relevant national and local specifications for the firefighting design of such projects.For this reason,taking the Tian'edang depot and its topside property development project of Suzhou rail transit line 7 as the research target and on the basis of elaborating the principles and difficulties of firefighting design of the depot and its topside property development project,analysis is carried out against the design and requirements of key technical measures of the depot under the cover and the superstructure under the cover,such as firefighting lanes and exits and entrances,fire hazard category and fire resistance rating of the single unit,fire compartment and separation measures,safety evacuation distances,fire prevention distances,automatic fire extinguishing facilities,power distribution for firefighting,firefighting loads,emergency lighting for firefighting lanes,smoke evacuation of the warehouse and firefighting lanes,etc.,respectively,and put forward specific suggestions and measures for firefighting design,so as to provide reference and an example to build on for the relevant practice of similar projects.
