Core Viewpoint - The construction of Nanjing North Station is progressing rapidly, with significant infrastructure developments aimed at enhancing regional connectivity and supporting economic growth in the Yangtze River Delta region [1][6]. Group 1: Construction Progress - The Nanjing North Station project includes three main parts: the front station, station building, and rear station, with the front section primarily serving the Ninghuai Intercity Railway [1]. - The Nanjing Special Bridge, a key component of the project, features a total of 67 piers and spans approximately 2.5 kilometers, with the recently completed continuous beam consisting of 18 segments [3]. - The continuous beam design employs an innovative "single box double chamber" structure, enhancing torsional performance and lateral load capacity [3]. Group 2: Construction Techniques - The project utilizes a large-span fully enclosed hanging basket construction technique, which minimizes noise and dust while ensuring the normal flow of traffic on the busy Hu-Shan Expressway [3]. - The construction process incorporates a "smart construction site" system, which includes real-time monitoring of structural parameters through hundreds of sensors, ensuring quality control within millimeter precision [5]. Group 3: Safety and Quality Management - Safety measures include the installation of bolt loosening warning devices and visual alarm systems on cranes, providing dual safety guarantees during high-altitude operations [5]. - A comprehensive steel structure protection system has been established to prevent falling objects, along with 24-hour monitoring and emergency response plans in collaboration with traffic management authorities [5]. Group 4: Future Developments - Upon completion, Nanjing North Station will serve as a crucial hub for the North Yangtze River artery, facilitating integrated development in the Yangtze River Delta and the Yangtze Economic Belt [6]. - The city plans to accelerate the construction of related projects, including the North Yangtze River High-Speed Railway and the Ninghuai Intercity Railway, to enhance urban influence and connectivity [6].
