上海长江路隧道通风系统创新技术应用

Innovative Application of Ventilation System in Shanghai Changjiang Road Tunnel

上海长江路隧道可通行集卡,且火灾热释放率大、用地条件紧张,因此通风设计采用了单端式重点排烟系统、压盖式排烟口、大口径轴流风机等新技术和新设备以满足运营防灾需求。结合工程实际,对通风系统技术创新点作了归纳整理,可供类似的工程设计参考。

Shanghai Changjiang Road Tunnel allows the passage of container lorry with high fire release rate.In order to meet the disaster prevention requirements and considering the limited space for E&M equipment installation,new technologies and equipment are used such as single end concentrated smoke exhaust system,smoke exhaust vent with lid and large diameter axial fan in the ventilation design of Shanghai Changjiang Road Tunnel.Combined with the engineering practice,the innovations in the ventilation system are summarized which will provide reference for the design of similar projects.
