[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

Recently, the first 33 kV collection line of the 96.9 MW photovoltaic project in Vaira, Peru was successfully powered once. The live equipment is running stably, and the project has officially entered the live commissioning stage. After the completion of the project, the average annual power generation is expected to reach 250 million kilowatt hours, which can meet the annual electricity demand of about 230000 Peruvian households and reduce carbon dioxide emissions by about 150000 tons per year.Editor/Cheng Liting
