A super-large-diameter shield tunneling machine "Yongzhou" rolled off the assembly line in Changsha on February 26, 2024. It was jointly developed by the China Railway 14th Bureau Group Corporation Limited and the China Railway Construction Heavy Industry Corporation Limited. With a Chinese dragon pattern on its cutterhead, the machine is 135 meters in length and its excavation diameter reaches 14.57 meters. It will be utilized in the construction of Jintang Undersea Tunnel-the world's longest undersea high-speed railway tunnel linking Ningbo and Zhoushan. (Photo/Li Jian)
