中国造硬岩隧道掘进机贯通东南亚第一长铁路隧道

Core Viewpoint - The successful completion of the "Genting Tunnel," the longest railway tunnel in Southeast Asia, marks a significant achievement for the Malaysia East Coast Rail Link (ECRL) project, showcasing advanced engineering capabilities and contributing to regional economic development [1][2]. Group 1: Project Overview - The Genting Tunnel is a key control project of the ECRL, measuring 16.39 kilometers in length and reaching a maximum depth of 750 meters, recognized as the longest and highest coverage railway tunnel in Malaysia [1]. - The tunnel traverses the Titiwangsa mountain range, characterized by extremely challenging geological conditions, including 200 MPa ultra-hard granite and high quartz content in schist, presenting significant construction difficulties [1]. Group 2: Technological Innovations - The "Genting Twins," the open-type TBMs "Genting No. 1" and "Genting No. 2," were developed by China Communications Construction Company (CCCC) to address major construction challenges, featuring a cutter head diameter of 8.98 meters and a total weight of 2,500 tons, with a domestic production rate of 98% [1]. - The TBMs incorporate advanced technologies, including a comprehensive support system and over 70 innovative techniques, ensuring effective tunneling through complex geological formations [1][2]. Group 3: Economic Impact - The completion of the Genting Tunnel lays a solid foundation for the full operation of the ECRL, which is expected to significantly boost the economic development of Malaysia's East Coast and facilitate the transformation of logistics along the "Land Bridge" [2].
