my country's first cross -sea high -speed railway spreads through the line

This morning, with the last set of 500 -meter long rails at Xiamen North Station of Fuxia High Speed ​​Railway, it was successfully laid on the road bed. my country's first cross -sea high -speed rail -Fuxia high -speed railway was opened.

The total length of the Fuxia Railway's main line is 530 kilometers. This rail paving uses the domestic advanced two -line long -rail laid units, that is, the rail paving vehicle can directly laid the left and right lines without the need to turn on the line. It has improved by 60%of the operating efficiency than traditional rail paving units, and the daily progress can be laid by about 6 kilometers.

The entire bridge -tunnel ratio of the Fuxia High -speed Railway is as high as 84.3%, and there are technical problems such as difficulty in communicating communication, vehicle positioning and vehicle speed monitoring difficulties. To this end, the construction and construction unit uses the most advanced domestic layout comprehensive command scheduling system in China, and will be the most advanced layout of the gripping frame. Functions such as wireless network transmission and positioning navigation are integrated into the dispatch system, and the intelligence, informatization, and visual management of scheduling and command are realized.

The Fuxia High -speed Rail is an important part of the coastal channels of the "Eight Eights and Eight Heng" high -speed railway engineering network in my country. The design speed is 350 kilometers per hour, and the main line is 277.42 kilometers. There are 8 stations across the board.
