Core Viewpoint - The successful completion of the first tunneling task by the large-diameter earth pressure balance shield machine developed by the company in Sicily, Italy, marks a significant achievement in the Messina-Catania railway project, showcasing the company's advanced manufacturing capabilities and commitment to international markets [1][3]. Group 1: Project Details - The shield machine has a diameter of 9.36 meters and is responsible for a total tunneling task of approximately 12.54 kilometers in the project [3]. - The first section that achieved tunneling completion is 2.44 kilometers long, facing complex geological conditions including shale, phyllite, gravel, basalt, and sandstone, with rock uniaxial compressive strength ranging from 4 to 45 MPa [3]. Group 2: Technological Innovations - The shield machine incorporates advanced technologies such as permanent magnet synchronous drive, high-quality power supply systems, synchronous pushing technology, automated equipment management, intelligent tunneling parameter control, automatic segment hoisting, ultra-high pressure system rescue, and automatic trolley steering [3]. - These innovations enhance the machine's high-end intelligent attributes and green energy efficiency, significantly improving overall construction efficiency [3]. Group 3: International Collaboration and Service - The company provided a professional after-sales team to ensure smooth assembly and tunneling processes, overcoming challenges such as limited space, high-altitude high-voltage cables, and potential harmful substances in the geological layers [5]. - The machine achieved a maximum daily advance rate of 30.6 meters and a monthly advance rate exceeding 500 meters, demonstrating its operational efficiency [5]. Group 4: Strategic Implications - The project involves a total of four shield machines of the same specifications, with the successful tunneling of the first section laying a solid foundation for subsequent construction [5]. - This achievement exemplifies the company's "overseas priority" strategy and highlights the reputation of "Chinese manufacturing" in the high-end European market [5].
