[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

• CCCC SDC undertook the construction of the Zhangpu tailwater discharge project in Fujian. The submarine curved top pipe successfully crossed the basalt rock layer and entered the dense sand layer for excavation. This project is the first of two processes, and after completion, it will collect the deep-sea discharge of tail water from six sewage treatment plants to assist in the ecological governance of nearshore waters.
