运营线路地铁风管改造工程的施工要点分析

Analysis of the Construction Essentials of the Subway Air Duct Renovation Project on the Operating Line

在地铁列车运行中产生的活塞风气流,在长时间的气流冲击和振动的作用下,可能出现风管托吊架松动和风管脱落的现象,对列车的行车安全构成严重威胁。论文以北京地铁10号线改造工程为例,在结合暖通空调系统施工具体实践经验的基础上,对该地铁改造工程的风管改造施工要点进行阐述。

In the operation of subway trains, the piston air flow generated by the long-term impact and vibration of the air flow may cause the air pipe support and hanger to loosen and the air pipe to fall off, which poses a serious threat to the safety of the train. This article takes the reconstruction project of Beijing Metro Line 10 as an example, and describes the main points of the air duct reconstruction construction of the subway reconstruction project based on the specific practical experience of the HVAC system construction.
