CCTV.com News: The Chongqing-Kunming High-speed Railway, with a total length of about 700 kilometers, is an important part of the Beijing-Kunming Channel of my country's "eight vertical and eight horizontal" high-speed railway network. Among them, the Luoze River Super Bridge located in Yunnan is a key and difficult control project of the Chongqing-Kunming High-speed Railway, and the main project of the bridge pier is completed on February 18. After the full opening of the Chongqing-Kunming high-speed railway, the driving time from Chongqing to Kunming will be shortened from the current 5 hours to the fastest of about 2 hours, and Kunming to Chengdu is expected to be controlled within 3 hours. For the specific situation, let’s take a look at the report sent back by a reporter from the Central Station earlier.
Located on the No. 3 bridge pier platform of Luozehe Super Bridge in Yiliang County, Yunnan Province, the distance here is 150 meters, which is equivalent to the height of more than 50-story buildings. We see here that these dense steel bars must be tied to a standard of 10 cm apart. Workers walking through the steel bar forest work as meticulously as knitting sweaters to ensure that the construction meets the standard requirements. With the advancement of this process, it marks that the main project of the bridge pier has been completed and has entered the upper construction stage.
The Luoze River Super Bridge is 524.9 meters long and is currently the prestressed concrete bridge with the largest span, the highest pier and the highest slope of the high-speed railway with a speed of 350 kilometers per hour in my country. The bridge is located in a very special geographical location. It spans deep canyons and connects with the tunnel at both ends. It is a typical V-shaped landform of "two tunnels and one bridge" on mountainous railways.
According to the construction schedule, the Luoze River Super Bridge will be integrated within this year, so the entire construction has gradually entered the sprint stage. Now, not only are the workers on the bridge pier stepping up their work, but in the bottom area of the bridge, we can see that more than 10 construction workers are assembling the formwork. After the workers assemble the small components on the ground, they will hoist the whole to the location where we are now, and then pour the concrete.
The construction of 107 bridges in the Yunnan section of the Chongqing-Kunming High-speed Railway has been completed by more than 85%, 35 tunnels have been completed, and more than half of the box girder erection task has been completed. According to the Kunming Bureau of the National Railway, the entire Chongqing-Kunming High-speed Railway is expected to meet the opening conditions around December 2026.
