At a depth of more than 50 meters underground at the mouth of the Yangtze River, the 145-meter-long “Jianghai” shield is like a steel giant, moving steadily at the bottom of the river. On December 3, the domestic super-diameter shield machine “Jianghai”, which undertook the task of excavating the right line of the Haitai Yangtze River Tunnel, successfully broke through the 3,000-meter mark and completed nearly one-third of the total excavation mission. This marks a new stage in the construction of this world-class underwater tunnel project. According to Zhang Ga, captain of the “Jianghai” shield for the Haitai Yangtze River Tunnel Project, the shield has now excavated 1,500 rings and 3,000 meters, 15 days ahead of schedule.
