Four -rails of Fuxia High -speed Railway are connected!

yesterday morning

With the Fuxia High -speed Railway Xiamen North Station

The last group of 500 -meter long rails is successfully laid on the road bed

Mark the entire line of the Fuxia high -speed rail!

Fuxia High Speed ​​Railway

The Fuxia High -speed Railway starts from Fuzhou City in the north, passes through Putian City, Quanzhou City, to Xiamen and Zhangzhou in the south. 277.42 kilometers long, and there are 8 passenger stations in Fuzhou South, Fuqing West, Putian, Quangang, Quanzhou East, Quanzhou South, Xiamen North, and Zhangzhou.

● Meizhou Bay cross -sea bridge, located in Putian City and Quanzhou, with a total length of 14.7 kilometers. Among them, the construction length of the sea area is 10.8 kilometers. It is the first domestic high -speed rail short tower cable -keeping bridge with a design speed of 350 kilometers per hour.

● Quanzhou Bay Cross -sea Bridge, located in Quanzhou City, with a total length of 20 kilometers, of which the construction length of the sea area is 9 kilometers.

● Anchi Bay Bridge, located in Quanzhou City, connects Jinjiang City and Nan'an City in the jurisdiction, with a total length of 9.46 kilometers, of which 1.56 kilometers in the cross section of the sea. The main bridge across 300 meters and span the 2,000 -ton main channel of Anwan, which is one of the key control projects across the line.

It is worth mentioning that in the construction of my country's high -speed rail, the Anhai Bay Bridge was laid on the cross -sea cable -catch bridge for the first time. The speed of 350 kilometers per hour can cross the sea by crossing the sea without slowing down. By 7 seconds. The bridge is laid without orbit, which requires the bridge to have a good structural stiffness and power performance. The main beam of the Fuxia High -speed Railway Bay Bridge adopts effective and pneumatic measures to reduce the vibration of the wind in the complex air environment. Specify the "seamless docking" of high -speed rail speeds and land.

In addition, 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 growing tunnel communication, vehicle positioning and vehicle speed monitoring difficulties. To this end, the construction and construction unit uses the most advanced domestic layout comprehensive command and dispatch system in China. It also integrates functional integration of wireless network transmission, positioning navigation into the dispatch system, and realizes the intelligence, information, and visual management of scheduling and command, effectively overcome various technical problems, and ensure that the Fuxia high -speed rail is high -quality to complete the entire rail paving work on time.
