Content Validity:In Changsha, Hunan, an engineering marvel has been unveiled! The largest diameter single-shield TBM in China, 'Jianghan Yunmeng,' has made its grand debut, ready to take on the challenging Yinjiang Bughan project. This colossal machine, with a diameter of 12.23 meters, 140 meters long, and weighing 3200 tons, boasts a turning radius of 600 meters and can handle slopes up to 10%, tunneling 11.77 kilometers. Facing complex geological conditions, the R&D team has innovated, equipping 'Jianghan Yunmeng' with advanced technologies like intelligent boring and ultra-high-pressure disentanglement, providing strong support for intelligent project supervision. This is not just a technological breakthrough; it marks the beginning of a close connection between the South-to-North Water Diversion Project and the Three Gorges Project, bolstering the country's water security.
