A few days ago, with the overall layout of the Anchi Bay Bridge, the construction tasks of the three -seater cross -sea bridge of the Fuxia high -speed rail -Meizhou Bay cross -sea bridge, Quanzhou Bay cross -sea bridge, and Anhai Bay Tail Bridge rail paving all ended.

The Meizhou Bay Cross -sea Bridge is located in Putian City and Quanzhou City. It is 14.7 kilometers in length. 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.

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

The Antai Bay Bridge is located in Quanzhou City. It is connected to Jinjiang City and Nan'an City in the jurisdiction. The total length is 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 2023, after the opening of the Fuxia high -speed railway, it will inject new kinetic energy into the accelerated rise of the two major cities in Xiamen and Zhang and Fuzhou, and the regional economic and social development along the route -Xiamen and Fuzhou will form a "one -hour life circle", Xiamen and Zhang, Zhang, Zhang The "half -hour transportation circle" in Quan and other places, the southeast coastal urban agglomeration will connect a "golden tourist belt".
