Changtai Yangtze River Bridge is the first "trinity" cross-river channel on the Yangtze River that integrates expressways, intercity railways and ordinary highways. It has set many "world's best" and "global firsts". The reporter of "China's New Landmark" climbed to the commanding heights of the world's highest cable tower at key construction points to see how the world's highest-strength cable-stayed cables are "threaded and threaded" to accurately hang them, and to reveal more secrets behind the construction of the bridge one by one. Hard core technology.

In June of this year, with great expectation, reporters from the main station went to the Changtai Yangtze River Bridge under construction. Why are you looking forward to it so much? Because reporters have long heard that this bridge has achieved many "world's best" and "world's first" achievements. For example, it is not only the longest-span road-rail dual-purpose cable-stayed bridge under construction in the world, but it also has the world's largest span. The tallest cable tower, the largest steel caisson in water and the most tensile stay cable.

When the reporter went to the scene, it happened to catch up with the final stage of installation of the last few stay cables. You can see how the world's most tensile stay cables are hung in the world's tallest cable tower. , which requires climbing the 350-meter-high main tower. How high is it? The reporter changed elevators three times, which took more than 20 minutes, and finally climbed three ladders before finally reaching the top of the tower. Standing on the top of the tower and looking towards the river, I saw that it was 120 stories high. My legs were really weak.

On such a cable tower, which is the tallest in the world, workers need to operate a winch to hang the 633-meter-long stay cable, which weighs more than 100 tons, into the cable hole of the 350-meter-high bridge tower. This is like threading a huge, heavy and long thread into the eye of a needle 350 meters high. It can be imagined that the accuracy of its operation is very high.

Through the installation process of stay cables, we can really feel the behind-the-scenes of a world-class super project, which requires the precision of operation in exchange for the height of the building, the span of the bridge and the speed of construction.

So in addition to cable stay installation, what other hard-core technologies are involved in the construction of the Changtai Yangtze River Bridge? After the bridge is opened in the future, what changes will it bring to the travel of local people, the development of enterprises, and the cross-river integration in the region? To learn more about the Changtai Yangtze River Bridge, please pay attention to the large-scale series "China's New Landmark" that will be broadcast tomorrow (September 9) by cctv-4 "China News".
