摘要
北京地铁9号线科怡路站基坑采用钻孔灌注桩十钢支撑体系,通过严格控制土方开挖、挂网喷射混凝土、钢支撑(围檩)安装等关键技术细节,并实行细致的监控量测和信息化施工,确保了明挖基坑自身和周边环境的安全。
Bored pile and steel support system were adopted in the foundation pit construction of Keyilu Station of Beijing Subway Line 9. Strict control was realized in various key technical details, such as earth excavation, screen sprayed concrete, steel support （enclosure purlin） installation, etc., and monitored measurement and information-based construction were executed to ensure the construction and environmental safety of openly excavated foundation pit.
