Core Viewpoint - The "Wanmei Electric Power" shield tunneling machine has been launched in Guangzhou and will be utilized in the State Grid's Wuhu GIL (Gas Insulated Transmission Line) corridor project crossing the Yangtze River [1][3]. Group 1: Project Overview - The Wuhu GIL corridor project, located in Wuhu City, Anhui Province, is a crucial part of the Gansu-Zhejiang ±800 kV UHVDC transmission project, featuring a total tunnel length of 3,600 meters, making it the largest power corridor project under construction in terms of diameter in inland areas [3][5]. - The underground pipeline installation method, as opposed to an elevated ground solution, efficiently saves space, does not interfere with Yangtze River navigation, and ensures transmission stability unaffected by terrain and weather [3]. Group 2: Technical Specifications - The "Wanmei Electric Power" shield tunneling machine has a cutter head diameter of 12.13 meters, a total length of 150 meters, and a weight of 2,300 tons, with a total power of 6,900 kW and 116 cutter tools, including 72 replaceable tools for normal pressure [5]. - The machine is equipped with advanced technologies for tunneling through complex geological conditions, including interchangeable normal pressure rolling cutters, main drive telescoping, and synchronous double-liquid grouting [5]. - Intelligent control systems for tunneling posture, cutter wear detection, and advanced geological forecasting are integrated to ensure safe and efficient tunneling operations [5]. Group 3: Project Timeline and Impact - After factory manufacturing, the shield machine will be disassembled and transported to the construction site via water and land, with assembly and testing expected to begin, aiming for tunneling to commence by the end of March 2026 [7]. - This tunnel represents the most geologically complex and challenging power shield tunnel currently under construction on the Yangtze River, and its completion will effectively address cross-river transmission challenges, enhancing the power exchange capacity and reliability of the East China power grid [7].
