A domestically produced 15-meter diameter super-large shield tunneling machine that can balance water and mud rolls off the production line on Sunday in Hangzhou, East China's Zhejiang Province. The machine weighs 4,300 tons and is about 120 meters long, making it the largest shield machine in East China. It will be used to build two-way 4+4 lanes on the ground and underground, a three-dimensional transportation network in Hangzhou. Photo: VCG
