Measurement and optimization of smoke exhaust systems in equipment area corridors of an underground railway station

Taking the smoke exhaust system of the equipment area corridor of an underground railway station as the research object, carries out two smoke emission tests. According to the results of the first smoke discharge test, summarizes the reasons and carries out the second smoke discharge test after optimizing the smoke exhaust system. The results show that the optimized smoke exhaust system has fast smoke exhaust and good air distribution. Analyses and summarizes the design of smoke exhaust system in equipment area corridor, and puts forward optimization measures and suggestions to provide reference for the design of smoke management systems in similar projects.
