地铁车站狭窄场地施工技术研究

Research on Construction Technology of Narrow Site of Subway Station

暗挖施工因占地面积较小、对周边环境影响小,不影响道路交通,竖井设置对场地要求较低,且竖井设置为可全封闭施工,对周边居民、单位影响程度降至最低。因此,城市地铁建设中,越来越多的车站选择暗挖施工法。竖井是进入车站主体暗挖施工的第一道工序,其选址、施工质量和安全尤为重要。本文以青岛地铁1号线工程土建Ⅱ标-05工区施工临时竖井为例,结合现场实际,分析探讨狭窄场地临时竖井与车站主体相结合施工技术方案,以期为类似狭窄场地条件下地铁施工提供参考。

Due to the small area of the underground excavation construction,the impact on the surrounding environment is little,and the road traffic is not affected.The setting of the shaft has low requirements on the site,and the shaft can be set to be fully enclosed,so the impact on the surrounding residents and units is minimized.Therefore,in the construction of urban subways,more and more stations are being constructed by underground excavation.The shaft is the first process of underground excavation into the main body of the station.Its site selection,construction quality and safety are particularly important.This paper takes the actual construction of temporary shaft in the construction area ofⅡstandard-05 of Qingdao Metro Line 1 project as an example,and introduces the construction technical scheme of combing the temporary shaft in narrow site with the main body of the station,expecting to provide reference for subway construction under similar narrow working conditions.
