Line 9 Phase 1
Successful passage of the double line between Guanziqiao Station and Jiangdongmen Station
Recently, as the shield machine cutter plate broke through the wall, Line 9 Phase I Guanziqiao Station ~ Jiangdongmen Station interval (hereinafter referred to as "Guanjiang Interval") left line shield was successfully received, marking the smooth passage of the Guanziqiao Station ~ Jiangdongmen Station interval in both lines.
The whole line of Guanjiang interval is located in the diffuse stratum of the Yangtze River, and the hydrogeology of the interval is silty powdery clay layer, with poor soil self-stability. Jiangdongmen Station and Guanziqiao Station are located in Jiangdong Expressway, the main road of Nanjing, with many neighborhoods and stores, and many pipelines, and the shield machine has crossed many pipelines and buildings (groups). In the face of the complex surrounding environment, shield through the difficult construction difficulties, Nanjing Metro organization experts to demonstrate, develop special programs, and make every effort to crack the technical challenges. Both lines of the tube river interval adopt the "cup type" horizontal freezing reinforcement method of starting and receiving program, the overall effect of horizontal freezing reinforcement is good, and the receiving end cancels the steel sleeve, reduces the work process, shortens the work period, and finally realizes the safe starting and receiving of the shield structure, and lays a solid foundation for the subsequent track laying and installation work.
Nanjing Metro Line 9 Phase I project starts from Hongshan New City Station, finally Jiangsu Grand Theater - Constitution Square Station, the line length of 19.684 kilometers, all for the underground line, a total of 16 stations, including 9 interchange stations. The line passes through Xuanwu District,Drumtower city district (various)The city's main city, Jianye District, will be the main city of Nanjing's internal connection after completion of the operation.Central Heshi,Shimonoseki (Japan)with an important local line in the Shinjo area.
