The ongoing excavation of the tunnel under Yangtze River, carried out by the world's largest diameter high-speed rail shield tunneling machine the "Linghang" that is independently developed by China, has exceeded the 10,000-meter mark on Tuesday, which laid a solid foundation for the completion of the tunnel.
