Only 15 meters left!The latest news of the Danjiangkou Reservoir Bridge of the Shixia Expressway

Reporter Liu Kun

Recently, in the Danjiangkou Reservoir area, which is rippling, the Danjiangkou Reservoir Turbus of the Shixia Expressway can only be "step" to cross the rippling reservoir. The special bridge is planned to hang the last section of the steel box beam in mid -August.

The design line is 112 kilometers in length, the ten -淅 highway, starts from Dingjiaying Town, Danjiangkou City, and interoperate with the intersection of Fuyin Expressway. After entering the territory of Henan in Shigu Town, via Kuangfang Town, Xichuan County, to the north through Shengwan Town, Ma Chongzhen, and then bypassing the county town in the northwest, and continued to reach the end of Luanxi Expressway and Shanghai -Shaanxi high -speed crossing hub to the north. About 20 billion yuan. Among them, Danjiangkou City is 41.1 kilometers long and invested about 7.4 billion yuan. It is constructed according to the standards of two -way four -lane standards, with a design speed of 100 kilometers per hour.

The ten high -speed high -speed speeds undertaken by the Second Airlines Bureau of China Communications were labeled in Liangshuihe Town, Danjiangkou City, crossing the Danjiangkou Reservoir to the south, and ends in Longshan Town, Danjiangkou City, with a total length of about 15.8 kilometers. kilometer. The key control project of this project -Danjiangkou Reservoir Bridge is the main cross -noodle part of the two -tower double cable part of the two -tower dual -cable parts of the two -tower double cable beam. About 395.7 meters, weighing 54.1 tons. The cross-bridge has a 48-beam beam section, and the steel-UHPC light combination beam structure is adopted. The largest heavy beam section is 16 meters long, 31.6 meters wide, 3.8 meters high, and weigh 417.4 tons.

Reporter's interview learned

After this super bridge is completed

Will create three "world first":

The world's largest span -part -part anchor -type cable bridge

The world's largest axisless force connection device

The world is used for the first time in the world

New Steel-UHPC light combination beam

In addition, only more than 10 new materials and new processes on this super bridge are used. Among them, there are a number of applications that belong to the first application or at the industry's leading level: CFRP high-strength carbon fiber anchor application; invention of new cross-medium-free connection devices with damping locking function; Drilling the construction method of large diameter pile foundation of the slope hard rock layer, the ground anchor hybrid beam holding bridge anchor bridge anchor bridge into a set of fissure construction methods ...

The China Communications Second Airlines Bureau, which contracts the bridge, stated that to build this bridge with high standards, it is necessary to boldly innovate in craftsmanship and technology. The R & D team carefully calculates the stress point of the bridge deck, adheres to independent innovation in technology and technology, and dares to "hard bones" in technology!

As a new fast channel connecting the Fuyin Expressway and the Shanghai -Shaanxi Expressway, the Shixia Expressway is an important part of the "Five Vertical and Four" nine arteries of the "Thirteenth Five -Year Plan" traffic plan for Hubei Province. After the project is completed, it will not only become an important basic guarantee for the comprehensive promotion of rural rejuvenation in Qinba Mountain area, but also connect the three major scenic spots of the Three Gorges Reservoir, Danjiangkou Real Estate, Shennongjia, Wudang Mountain, and Luoyang of the Thirteen Dynasties. Promote the rapid development of the ecological and cultural tourism industry along the route, and become a tourist road and a way to benefit the people of the region.

The "Last Holding Hand" process includes

Hanging, fine tone, docking, welding

Waiting for construction steps

Then

This "most" at the bridge of the world

Take the north coast with one hand

Hold the south bank in one hand

Unicom north and south, Tianyu becomes a way!
