[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

• [The first collaborative green power project in China has been put into operation]
• On May 2, 2026, China's first large-scale "collaborative computing and power" green power direct supply project, the Zhongwei Cloud Base 500000 kW photovoltaic power station, was officially put into operation. The 1.5 million kilowatt wind power supporting the project will be connected to the grid in September, which can meet the annual electricity demand of the data center as a whole. The project innovation adopts a dual track power supply mode, with complementary wind and solar power to ensure all-weather green power supply. After the completion of all projects, the local area will form a green power supply scale of 4.6 million kilowatts, which will help the implementation of the "East Calculation and West Calculation" project.Editor/Gong Ziwei
