The main foundation pit of the station with the largest volume has been sealed, and the new progress of the Shanghai Municipal Railway Airport Connection Line | Foundation Pit | Volume
The construction of Sanlin South Station on the Shanghai Municipal Railway Airport Connection Line has made new progress recently. The reporter learned from Shanghai Shentie that the main foundation pit of the station has been sealed and will enter the stage of structural backfilling construction.
Sanlin South Station is the largest airport connecting line station and currently one of the largest under construction station projects in Shanghai. It is an underground four story station, and the excavation of the foundation pit faces challenges such as large scale of ultra deep foundation pit, deep excavation, low excavation efficiency, and high requirements for deformation control of the foundation pit. In response to these unfavorable factors, Shanghai Shentie has deployed arrangements in advance, and the project team and various participating units have worked together to adjust the excavation process of the foundation pit according to the geological environment at different depths on site. After each layer of earthwork excavation is completed, the deformation of the foundation pit is analyzed and judged in a timely manner, accumulating experience for the next layer of excavation and orderly promoting the overall construction of the foundation pit.
