浙江舟山：钢桥梁智造加速甬舟铁路建设

Group 1 - The Xiapu Bridge is the world's largest road-rail dual-use bridge and a key control project for the Ningbo-Zhoushan Railway, which will end the history of no railway access in Zhoushan City [1] - The bridge features a dual-layer design with a railway in the middle and roads on both sides, including a double-track railway and a six-lane dual-direction road [1] - The construction involves over 30,000 tons of steel structures, which are being divided into 138 intelligent modules with a precision control of within 2 millimeters [1] Group 2 - The intelligent manufacturing base at China Railway Baoji (Zhoushan) Co., Ltd. employs smart welding robots and other automated equipment, significantly enhancing production efficiency by over 40% [2] - The welding quality is crucial for the safety and performance of the bridge, with weld seams being evaluated at a level comparable to that of a senior welder [2] - The integration of "artificial intelligence+" welding technology allows for precise identification of welding positions and immediate alerts for any issues detected [3] Group 3 - The bridge utilizes a cable-stayed suspension system, necessitating precise control of steel structures due to varying stress points across different segments [3] - In 2022, China Railway Industry established a large-scale, intelligent steel bridge manufacturing base in Zhoushan, enhancing China's capabilities in steel bridge manufacturing [3]
