世界最大直径竖井掘进机“启明号”在江苏太仓始发

Core Viewpoint - The world's largest diameter vertical shaft tunneling machine, "Qiming," has commenced operations in Jiangsu Taicang, marking a new era for high-speed railway vertical shaft construction in China [1] Group 1: Project Overview - "Qiming" was launched on January 13 and is being utilized for the construction of the No. 2 vertical shaft of the Chongming-Taicang Yangtze River Tunnel [1] - The Chongming-Taicang Yangtze River Tunnel connects Chongming District in Shanghai with Taicang City in Jiangsu and is the largest high-speed railway underwater tunnel in China, with a total length of 14.25 kilometers and three vertical shafts [1] Group 2: Significance and Impact - The completion of the No. 2 vertical shaft will facilitate the reception and secondary launch of the "Linghang" shield machine, laying a solid foundation for the full tunnel completion [1] - Once completed, the tunnel will significantly shorten the commuting distance between Shanghai and Jiangsu, enabling high-speed rail to cross the river without reducing speed, thus ending the historical lack of high-speed rail access to Chongming Island [1] - This project is crucial for the development of the "Railway on the Yangtze River Delta" and the high-quality integration of the Yangtze River Delta region [1]
