广湛高铁站前2标无砟道床施工完成

Core Viewpoint - The completion of the ballastless track construction for the Guangzhan High-speed Railway marks a significant milestone in the project, which is the longest and largest railway project in Guangdong Province, enhancing connectivity in the region [1][3]. Group 1: Project Overview - The Guangzhan High-speed Railway spans 401 kilometers, making it the longest and largest railway project in Guangdong Province [1]. - The section constructed by China Railway 25th Bureau covers 10.38 kilometers, including two major bridges and two segments of roadbed, with a total length of 8.2 kilometers of double-track ballastless railway [1]. Group 2: Construction Details - The construction of ballastless track is a critical phase that requires stringent control over geometric dimensions and precision, with track slab size deviations needing to be within 2 millimeters [3]. - The project employs a track slab framework method to enhance construction efficiency and maintain precision control at the millimeter level [3]. Group 3: Strategic Importance - The Guangzhan High-speed Railway is designed for a maximum speed of 350 kilometers per hour and is a key component of the national "Eight Vertical and Eight Horizontal" high-speed railway network [3]. - Upon completion, the railway will significantly reduce travel time between the western Guangdong region and the Guangdong-Hong Kong-Macao Greater Bay Area, allowing for a 90-minute journey from downtown Guangzhou to downtown Zhanjiang [3].
