Core Viewpoint - The Chengyu Middle Line High-Speed Railway's shield tunnel segment production has been completed three months ahead of schedule, showcasing advancements in automation and efficiency in the manufacturing process [4][6]. Project Overview - The project is managed by China Railway 11th Bureau and involves the production of shield segments for the Shuan Tunnel of the Chengyu Middle Line High-Speed Railway, officially starting operations in September 2023 [3]. - The factory has completed the production of 4,919 segments, ahead of the planned timeline [3]. Production Efficiency - The factory has achieved a 20% increase in production efficiency compared to traditional factories, with the implementation of an intelligent production management system [6][7]. - The workforce has been reduced from 91 to 34 workers due to automation, allowing for the completion of a segment every five to six minutes [6]. Technological Advancements - The factory utilizes an intelligent production management system that integrates 3D laser scanning and automatic detection technology, ensuring production tolerances are within 1 millimeter for various dimensions [7]. - A new online simulation assembly testing process has been introduced, significantly reducing the time required for quality assurance from three days to one hour [7]. Current Progress - As of now, the tunnel has progressed 8,380 meters, completing approximately 80% of the total engineering work [7].
