[Shenjiang No. 1 participated in the construction of the deepest submarine tunnel] On August 23, China's self-developed subsea tunnel shield machine rolled off the assembly line in Changsha, Hunan. The equipment shield machine has an excavation diameter of 13.42 meters, a total length of 130 meters, and a total weight of 3,800 tons. It will participate in the construction of China's deepest submarine tunnel-the Zhujiangkou Tunnel of the Shenzhen-Jiangmen Railway. The Pearl River Mouth Tunnel is a key control project of the Deep River Railway. "Shenjiang No. 1" crosses the section with a total length of 3590 meters. The entire line is tunneled downhill for a long distance and passes through the Pearl River estuary. The engineering geological conditions are extremely complicated. Editor/Xu Shengpeng
