[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 pile foundation of the approach bridge of the G107 Leiyang Ring Road crossing the Beijing Guangzhou Railway was successfully poured, and the project officially entered physical construction. The total length of the approach bridge is 471.4 meters, with 68 pile foundations and 113 box girders. The foundation of the bridge site is composed of soluble limestone, with developed karst caves and dissolution fractures, making pile foundation treatment extremely difficult. The project department ensures the quality of the first pile through measures such as drawing review, equipment debugging, and on-site monitoring throughout the process. In the next stage, we will summarize our experience, strictly control progress and safety, and assist in the early completion of the ring road.Editor/Cheng Liting
On May 8, 2026, the Mohan Industrial Park in Xishan Industrial Park, constructed by China Railway Assembly, officially started construction. The project is located in the Mohan Moding Economic Cooperation Zone, with a total construction area of nearly 30000 square meters. It will be built in two phases, with the first phase consisting of offices, factories, and supporting facilities, and the second phase expanding production capacity. After completion, it will fill the gap in the industrial carrying capacity of Mohan Port, strengthen the linkage between Kunming and Mohan, and provide hard support for cross-border industrial agglomeration and high-quality development of enclave economy.
