[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

• [Vietnam increases household photovoltaic policy]
• Vietnam has issued the latest directive to strengthen local responsibilities and promote the implementation of household rooftop photovoltaics. Require all provinces and cities to introduce incentive plans by the end of December 2026, with the Ministry of Industry and Trade setting installation targets and local governments independently developing subsidy mechanisms. The policy is synchronized with the development of energy storage, and the proportion of surplus electricity connected to the grid has been increased to 50%. The current installed capacity of rooftop photovoltaics in Vietnam exceeds 11.45GW, and there is a lack of supporting documents in many places. The new policy aims to alleviate the electricity shortage and ensure power supply.Editor/Gong Ziwei
