Just now!

Xiang'an Bridge (Xiamen Second East Channel) main line

Successful Heilong!

This is after the Hong Kong -Zhuhai -Macao Bridge

The second domestic and first place in Fujian Province

Full bridge prefabrication assembly cross -sea bridge

This time the main line was successful

Realize that the bridge between the bridge sea is all through

Lay the solid foundation to ensure the goal of opening the traffic

The steel box beams at the time of Helong are 72 meters long, 53 meters wide, 3.5 meters high, and weigh 2197.2 tons. It is the widest steel box beam in the bridge. The process is complicated and put forward higher requirements for the balance, safety, and accuracy of the lifting.

Before Helong, the project team of the China Communications Second Aviation Bureau combined the special structure of the Heilong section of the steel box beam to optimize the architecture to optimize the stress state by increasing the adjustment block to balance the steel box beam; Dynamic, deploy a beam beam boat, a lifting boat breakdown positioning, and achieve more than 10 large -scale equipment such as 4,000 tons of floating cranes, 1 10,000 -ton steel box beam transportation ships, in the same waters. Selecting the operation "window period" provides necessary conditions for precision cranes for steel box beams.

After the steel box beams of Helong section are located, the project adopts a three -way hydraulic jack. Through the intelligent sensor and the adjustment control system, the adjustment data will be integrated on the information platform, and the millimeter error is finally achieved.

Project business card

The Xiang'an Bridge is a key project of Fujian's first demonstration of the transportation country. It is an important part of the "one vertical" of the "six vertical and ten horizontal" planning high -speed road network in Fujian Province and the "two -ring eight shots" express road network in Xiamen. It is Xiamen. One of the important cross -sea channels in the city's traffic network planning is the seventh bridge tunnel cross -sea channel after Xiamen Bridge, Haicang Bridge, Jimei Bridge, Xinglin Bridge, Xiang'an Tunnel, and Haicang Tunnel. It started in December and is expected to be opened to traffic before the Spring Festival in 2023.

From the intersection of Jongzhong Road and Jin Shang Road in the west, and eastward, the continuous beam bridge across the waters of Xiamen, and finally Xiang'an Avenue, with a total length of 12.371 kilometers. Anthill is about 4.8 kilometers. The bridge is a single -frame transformation of the cross -section continuous beam bridge. The main line is constructed according to the two -way 8 -lane highway standard. The design speed is 80 kilometers per hour, and the design period is 100 years.

The prefabrication rate of the bridge pier and steel box beams in the bridge in the bridge is 100%. There are 35 prefabricated pier and 36 steel box beams on the entire line. Among them, the prefabricated pier platform adopts vertical dried sewing and matched pre -system method. It is the second domestic and Fujian Province after the Hong Kong -Zhuhai -Macao Bridge.
