西安地铁PBA暗挖车站施工 通风设计

Ventilation Design for Construction of PBA Underground Excavation Station in Xi'an Metro

地铁建设有效缓解了交通压力,为人们出行提供了便利,在PBA暗挖车站施工中要注重通风设计,保证达到工程质量要求。围绕西安地铁2号线二期工程何家营站PBA暗挖车站施工通风设计展开探讨,提出暗挖风道设置方式包括单独设置暗挖双层风道结构,车站主体加长布设风道设备,风道与区间结构合建,车站主体增跨布设风道设备,并对风道施工所需材料进行了分析。

The construction of the subway has effectively alleviated the traffic pressure and provided convenient conditions for people to travel.In the construction of the PBA underground excavation station,the ventilation design must be paid attention to ensure that the project quality requirements are met.Ventilation design for construction of PBA underground excavation station,the Hejiaying Station of the second phase project of Xi’an Metro Line 2,is discussed,the setting methods of the underground excavation air duct are put forward,including setting the double-layer air duct structure separately,arranging the air duct equipment in the lengthened main body of the station,constructing the air duct and the interval structure together,and arranging the air duct equipment in the increasing span of the main body of the station,and the materials required for the air duct construction are analyzed.
