This morning, with the successful laying of the last set of 500-meter-long steel rails on the track bed at Fuxia High-speed Railway Xiamen North Station , my country's first cross-sea high-speed railway, Fuxia-Xiamen High-speed Railway , has been laid across the entire line.
The main line of Fuxia-Xiamen Railway has a total track laying length of 530 kilometers. This track laying adopts the domestic advanced long-track laying unit of the two lines, that is, the track-laying car can directly lay the long track on the left and right lines without changing the line. Compared with the traditional track laying unit, the operation efficiency is improved by 60%, and the daily progress can lay about 6 kilometers of long track.
The bridge-to-tunnel ratio of the whole Fuxia-Xiamen high-speed railway line is as high as 84.3%, and there are technical problems such as difficulty in communication in long tunnels, difficulty in vehicle positioning and vehicle speed monitoring. The functions of wireless network transmission, positioning and navigation are integrated into the dispatching system, which realizes the intelligent, informatized and visualized management of dispatching command.
Fuxia high-speed railway is an important part of the coastal passage in my country's "eight vertical and eight horizontal" high-speed railway engineering network. The design speed is 350 kilometers per hour, and the main line is 277.42 kilometers long. There are 3 bays in the bay, and there are 8 stations on the whole line. After the railway is completed and opened to traffic, Fuzhou and Xiamen will realize a "one-hour living circle". (Headquarters reporter Wu Yanmin Lai Junlin)
