世界最大直径竖井掘进机在郑州下线

Core Viewpoint - The world's largest diameter vertical shaft tunneling machine, named "Qiming," has been launched in Zhengzhou, China, marking a significant technological breakthrough in the field of large-diameter vertical shaft equipment [1][2]. Group 1: Technological Innovations - "Qiming" features a dual-arm structure that integrates excavation, spoil removal, and guidance functions, equipped with innovative technologies for posture adjustment and settlement control [1][2]. - The machine is designed to operate efficiently in complex geological conditions, including soft soil, gravel, soft rock, and hard rock, enabling "manned supervision and unmanned operation" [2]. Group 2: Operational Efficiency - The maximum excavation depth of "Qiming" reaches 150 meters, addressing the technical challenges of underwater operations where visibility and control are limited [2]. - Compared to traditional vertical shaft construction, "Qiming" significantly reduces the number of personnel required on-site and shortens the construction cycle, thereby lowering operational risks [2]. Group 3: Industry Impact - The launch of "Qiming" signifies a new technological advancement for China in the field of super-large diameter vertical shaft equipment, further promoting the intelligent transformation and upgrading of infrastructure construction [2].
