[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
Zhongjin Lingnan's performance in the first quarter of 2026 was impressive, with significant year-on-year growth in revenue and net profit. The company's annual production of 860000 high-purity semiconductor substrates project is progressing smoothly, with construction starting in 2023. Currently, it has entered the trial production stage and is expected to officially enter mass production in the second half of this year. The total investment of the project is 424 million yuan, covering three major categories of gallium arsenide, indium phosphide, and germanium. Relying on independent core technology, after production, it will fill the gap in domestic high-end substrate production capacity, break the overseas monopoly, and become a new performance growth point for the enterprise.Editor/Gong Ziwei
On May 6, 2026, Pengyue Technology's Liuzhou semiconductor glass wafer and optical waveguide module project officially started construction. The company is a wholly-owned subsidiary of Guangzhou Semiconductor, and the project is undertaken by Alco. This is the second cooperation between the two parties after the Wuxi project. Guangzhou Semiconductor is a high-tech, specialized, and innovative enterprise that deeply cultivates high-end optical semiconductor technologies such as optical waveguides. It has cooperated with several leading smart glasses companies. The company has established a production base in Wuxi with a total investment of over 300 million yuan. After reaching production capacity, the annual output of optical waveguide modules can reach 1 million sets.Editor/Gong Ziwei
