Exploration and practice of Quality Control for Excavation of Rail Stations Based on Deep Excavation and Complex Surrounding Environment
In order to strengthen the management of deep foundation pit construction for subway stations and reduce its impact on the sur-rounding environment,this paper analyzes and discusses the quality control and management practice of deep foundation pit excavation for a certain subway station in Fuzhou.Based on the analysis of the basic overview,enclosure structure,engineering geology,and hydrogeology of the engineering project,the key and difficult points in the engineering management process are discussed.Based on the basic process and steps of excavation of foundation pit soil,important construction nodes during the excavation process were analyzed.On this basis,quality control points for important nodes such as earthwork excavation,enclosure structures,and large volume concrete construction are sorted out,and corresponding control measures are proposed for important management points during the foundation pit construction process.
