　　The reporter learned from Jingkun High-Speed Railway Xikun Co., Ltd. that on September 14, the No. 0 block of the No. 12 main pier of the Renhe Grand Bridge on the Xi'an-Chongqing High-Speed Railway, constructed by China Railway 12th Bureau Group, began pouring smoothly. This marks that the bridge construction of the Renhe Grand Bridge, a major and difficult project along the entire Xi'an-Chongqing High-Speed Railway line, has shifted from the substructure to the superstructure, and the entire bridge has entered the bridge deck construction phase.

　　The Renhe Grand Bridge is located in Chengkou County, Chongqing, with a total length of 1,180.52 meters. The Xi'an-Chongqing High-Speed Railway is an important component of the Beijing-Kunming corridor from Beijing to Kunming and the Bao (Yin)-Hai corridor from Baotou and Yinchuan to Haikou in China's "Eight Vertical and Eight Horizontal" high-speed railway network.
