World's first! China's first cross sea high speed rail, Fuzhou Xiamen railway is coming!

Описание: Not long ago, the entire FuXia high-speed rail line construction of the most difficult station Xiamen North Station facade decoration has been completed, the new Xiamen North Station is China's largest under construction wave-shaped station, the project will be opened in September for the whole line to lay the foundation for operation.

After the opening and operation of the whole line of Fuxia high-speed railway, passengers will usher in the brand-new experience of "sitting on the high-speed railway and seeing the sea". It is understood that the total length of Fuxia high-speed railway is 277.42 kilometers, with a design speed of 350 kilometers per hour, and it has become an engineering miracle marvel that makes the world marvel with several "world's firsts", and it has promoted the technology of high-speed railway bridges to the deep sea.

The whole line of Fuxia High-speed Railway borders on the bay, with the ratio of bridges and tunnels as high as 85%, 4 high-risk tunnels, and the existence of adverse geological conditions such as gushing water and mud, fault fracture zones, and air-mining zones, etc. In addition, there are many special bridges and complex structures, which makes the construction very difficult.

At the same time, there are more than one hundred places along the whole line of Fuxia high-speed railroad crossing or adjacent to highways and existing railroads, which makes the safety control difficult. Tunnel construction needs to pass through 9 faults, 4 rock intrusion contact zones and 8 joints dense zones, which is very easy to cause geological disasters such as water gushing. The maximum water influx reached 75,000 cubic meters. In addition, the tunnel's burial depth is 397 meters, which is equivalent to passing through a 100-story super-high-rise building, and there are adverse geological hazards such as high geothermal heat and rock explosion, making the construction very difficult.
