On the same day, the core components of the "Dinghai" shield machine on the Zhoushan side of the Jintang Submarine Tunnel of the Yongzhou Railway, which was constructed by China Railway 11th Bureau Group, were assembled, laying the foundation for the shield machine of the Jintang Submarine Tunnel of the Yongzhou Railway to cross the sea.
The Jintang Submarine Tunnel of Yongzhou Railway starts from Beilun District of Ningbo City in the west to Jintang Town of Zhoushan City in the east, with a total length of 16.18 kilometers, of which the shield section is 11.21 kilometers long. The Yongzhou Railway starts from Ningbo East Railway Station in the west to Baiquan Town, Dinghai District in the east, with 7 stations, with a total length of about 77 kilometers and a design speed of 250 kilometers per hour. After the completion of the project, it is of great significance to improve the layout of the railway network and promote the integration and development of Ningbo-Zhoushan.
