应用于世界规模最大城市湖底隧道盾构机在郑下线 “河南造”缘何频创新纪录

Core Viewpoint - The article highlights the successful development and deployment of a large-diameter slurry shield tunneling machine by China Railway Equipment, which is set to play a crucial role in the construction of the Wuhan Two Lakes Tunnel, the longest urban lake-bottom tunnel in China and the largest in the world [3][4]. Group 1: Project Details - The Wuhan Two Lakes Tunnel spans 2824.8 meters and is located at the bottom of East Lake, presenting significant construction challenges due to its steep gradient of 40‰ and tight turning radius of 700 meters, along with complex geological conditions [3]. - The custom-built slurry balance shield tunneling machine is designed to tackle these challenges, featuring advanced technology to ensure safe and efficient tunneling in complex strata [3][4]. Group 2: Technical Specifications - The tunneling machine measures 115 meters in length, weighs 4300 tons, and has a cutting diameter of 15.09 meters. It incorporates innovative features such as a dual-channel slurry discharge system and an automated mud cake removal system [4]. - Additional technologies include a constant pressure cutter head, advanced geological systems, and ergonomic designs to enhance human-machine interaction [4]. Group 3: Industry Impact and Future Directions - China Railway Equipment has achieved several milestones this year, including the largest diameter shield tunneling machine exported overseas and the first domestic shield tunneling machine to incorporate a "product ecosystem" for international markets [4]. - The company emphasizes the transition from "Made in China" to "Created in China," focusing on innovation and quality improvements, and plans to integrate AI technologies into the entire equipment development and manufacturing process [5].
