Recently, there is new development in Nanjing Metro: the connecting passage between Guanziqiao Station and Jiangdongmen Station of Phase I of Line 9 has been successfully completed .
Line 9 Phase 1 Guanziqiao Station ~ Jiangdongmen Station Section
The communication channel was successfully completed
On November 20, with the completion of concrete pouring in the pump room, the connecting passage between Guanziqiao Station and Jiangdongmen Station on Line 9 was successfully completed.
The liaison channel and pump house is located in the silty clay layer and is constructed using the freezing method. Nanjing Metro led all participating units to check the preparations for the excavation nodes of the liaison channel one by one to ensure that the preparatory work before construction is solid and in place. Since the excavation of the liaison channel, Nanjing Metro has strictly implemented the construction principles of short excavation, strong support, fast closure, and frequent measurement to ensure the smooth and orderly progress of the excavation of the liaison channel. In the overall construction organization plan and construction process, the principle of excavating one section, supporting one section, and closing one section is strictly followed. The main section has been completed, laying a good foundation for the subsequent transfer of track laying and installation, and realizing process conversion.
