Recently, the main structure of the large-mileage open-cut section of the running tunnel between the Logistics Park Hub Station and the Logistics Park North Station on Rail Transit Line 7 was successfully topped out, marking the complete conclusion of main structure construction for the entire running tunnel section. The main structure of this section has a total length of approximately 259 meters and a standard width of 24 meters, with a foundation pit excavation depth of 28 meters. Construction faced multiple difficulties, including complex cross-section transitions, dense underground pipelines, and large-slope roof slabs.

The project adopted BIM technology to optimize construction procedures, intelligent monitoring to strictly control risks, and segmented flow-line operations to ensure progress, completing the milestone objectives safely and with high quality, thereby providing strong support for the steady advancement of Phase I of the Rail Transit Line 7 project.
