There is no bridge pier on the surface of the river, the global span of the second super Yangtze River Bridge, and the Chinese infrastructure shocks the world

Bridge

China has always had the title of infrastructure madness, and has achieved many outstanding achievements in architecture. The Hong Kong -Zhuhai -Macao Bridge is known as the eighth major miracle in the world in the new century. However, China has never stopped exploring in the field of bridge construction. The projects with complex structure, long construction period, and large investment have continued to go to the horse. Following the Hong Kong -Zhuhai -Macao Bridge, the super Yangtze River Bridge with the second largest span in the world, Wuhan Yangsi Port Yangtze River Bridge has also been successfully built. There is no bridge pier on the surface of the river, and the infrastructure of China's infrastructure shocked the world.

Bridge

Bridge is a common building in daily life. Generally, highways need to cross the river, and bridges need to be set up. Nowadays, the strength of the bridge in China is impressive. A bridge without a bridge pier is built. Yangsi Port Yangtze River Bridge is the tenth Yangtze River Bridge in Wuhan. It is the largest suspension bridge in China. This city can be called the Yangtze River Bridge Museum. Every new bridge built has a good strength. representative work.

Bridge

As the first double -layer suspension road bridge on the Yangtze River, the main crossing 1700 meters, the best in the world. In order to build this bridge, Wuhan used the nation's top "bridge national team" to design and build. Non -motorized vehicles and sidewalks, this bridge has a total investment of more than 8 billion yuan. From construction in 2014, the total length is 4.13 kilometers. By 2019, it is opened. Because of the need to consider the demand for navigation.

Under the river surface between the Yangsi Port Bridge and the Parrot Island Bridge, there is a 3 kilometer of a submerged dam that was built by flood prevention and water. If a pier on the river surface is built, it will change the direction of the water flow and affect the water control project and ship sailing. Therefore The construction is called a bridge without a pier. The bridge is divided into two -story design, with a total of 12 lanes. The upper and lower lanes are both two -way lanes. It is people's action.

Bridge

The first ability of this bridge is that the 12 -level wind can not be blown. Before the construction, the bridge built an equal proportion to the reduction model. After a 2 -month hair drying test, it can withstand the 12 -level strong wind, and the 1.4 -meter isolation on the bridge is an isolation of 1.4 meters on the bridge. Bring, the anti -collision capacity reaches the world's highest specifications. The second housekeeping ability is that the main cable of the bridge is very strong and can not be changed for 100 years. A cable can be lifted. Tied together, each main cable can withstand 65,000 tons of tension.

The main cable of this bridge adopts China for the first time. In order to build a high -intensity main cable, the first super -strong steel wire production line is built in Qingdao. In the future In order to build a bridge, a total of 300,000 square meters of concrete were used, and the sinking well buried 8 basketball courts. From a distance, the bridge was very yellow in yellow. The bridge is the epitome of Chinese infrastructure.
