闹市区千年古刹内狭小空间基坑施工技术研究

Study on Construction Techniques of Foundation Pit in Narrow Space of Millennium Ancient Temple in Downtown Area

上海静安寺为市文物保护单位、汉族地区佛教全国重点寺院。在改扩建过程中,面临着对外开放状态下狭小空间深基坑开挖施工问题。在项目面临闹市区地下管线密集、紧邻周边建筑、环境保护要求高、基坑开挖较深等问题时,通过采用优化围护设计方案、细化土方挖运流程,采用信息化监控技术,顺利完成法堂、宝塔基坑施工,在确保闹市区千年古刹的正常法事活动的同时,有效保护了埋地的高压电缆和邻近大雄宝殿、综合楼等周边管线和建筑物。

Jing'an Temple in Shanghai is a cultural relic protection unit and a national key Buddhist temple in the Han nationality area.During the reconstruction and expansion process,it faced the challenge of deep foundation pit excavation in a narrow space while remaining open to the public.The project addressed issues such as dense underground pipelines,close proximity to surrounding buildings,high environmental protection requirements,and deep foundation pit excavation in a downtown area.By optimizing the enclosure design,refining the earthwork excavation and transportation process,and utilizing information monitoring techniques,the foundation pits for the law hall and pagoda were successfully constructed.This ensured the normal functioning of the ancient temple's activities in the bustling city while effectively protecting buried high-voltage cables and surrounding pipelines and buildings,such as the main hall and the complex building.
