en.Wedoany.com Reported - Pier No. 2 of the Hongzuiwan Bridge on the Hunan section's Bid 3 of the Yichang-Changde Railway was successfully concreted on the 20th. This is the first completed bridge pier column on the entire Yichang-Changde Railway line, marking a phased breakthrough in project construction and the official commencement of the above-ground main structure construction phase.
The Yichang-Changde Railway (Yichang to Changde High-Speed Railway) starts from Yichang North Station in the north, passes through Yidu City and Songzi City in Hubei Province, continues south through Li County and Linli County in Changde, Hunan Province, and connects to Changde Station. The newly built main line has a total length of 185.741 kilometers and a design speed of 350 kilometers per hour.
The pier column poured this time is located at the Hongzuiwan Bridge in Linli County, Changde City. The project is under the responsibility of the Hukun Passenger Dedicated Line Hunan Company for construction and is being built by China Tiesiju Civil Engineering Group. The construction environment in this work area is complex, and safety risks are relatively high. Pier No. 2 is a key pier position for the bridge, with a length of 6 meters, a width of 2 meters, and a height of 12 meters, requiring a designed concrete volume of 153.73 cubic meters. As the first pier on the entire line, China Tiesiju Civil Engineering Group strengthened safety and technical briefings for on-site workers, successively held first-pier construction promotion meetings and phase analysis meetings, conducted comprehensive analyses around processes such as rebar tying, formwork installation, and concrete pouring, formulated a specialized construction plan, and implemented checks at every level during the pouring process to ensure the entire procedure was safe, orderly, and controllable.
The Yichang-Changde Railway is a key component of the Hohhot-Nanning Corridor in China's "Eight Vertical and Eight Horizontal" high-speed rail network. It connects to the Zhengzhou-Wanzhou and Wuhan-Yichang high-speed railways in the north and the Changde-Yiyang-Changsha high-speed railway in the south, filling the high-speed rail gap between western Hubei and northwestern Hunan. Upon completion, the travel time from Yichang to Changde will be reduced from approximately 3.5 hours to about 1.5 hours, significantly compressing the temporal and spatial distance between cities along the route and strengthening connections among cities within the middle reaches of the Yangtze River urban agglomeration.
