合湛高铁广西段首榀箱梁浇筑完成

Core Viewpoint - The completion of the first box girder pouring for the Hezhang High-speed Railway in Guangxi marks the official start of box girder production, which is crucial for the project's progress and quality assurance [1][2]. Group 1: Project Overview - The Hezhang High-speed Railway in Guangxi spans approximately 139 kilometers with a designed speed of 350 km/h, serving as a significant part of China's "Eight Vertical and Eight Horizontal" high-speed rail network [5]. - The project is positioned as an important inter-regional passenger dedicated line and a new high-speed corridor connecting the Beibu Gulf, Pearl River Delta, and Yangtze River Delta [5]. Group 2: Construction Progress - The first box girder poured measures 32.6 meters in length and weighs 693 tons, utilizing advanced construction techniques such as intelligent tensioning and vacuum-assisted grouting [2]. - As of now, 2,975 bridge piles have been completed, and 79 bridge piers have been constructed, indicating steady progress in bridge engineering [5]. Group 3: Future Plans and Impact - The project aims to expedite land use approvals and land acquisition to facilitate the full commencement of the roadbed and other bridge constructions [3]. - The Hezhang High-speed Railway is expected to be completed and operational by the end of 2028, significantly enhancing railway transport capacity in Guangdong and Guangxi, optimizing regional railway network layout, and promoting high-quality economic development along the route [5].
