合武高铁引入合肥枢纽项目建设取得新进展 首联连续梁首段浇筑完成

Core Viewpoint - The completion of the first segment of the continuous beam for the Hefei-Wuhan High-Speed Railway (Hefei to Wuhan High-Speed Railway) marks a significant milestone in the construction of this important transportation project, which is part of China's national high-speed rail network [1][2]. Group 1: Project Overview - The continuous beam completed is located between piers 40 and 44 of the newly constructed Hefei-Wuhan main line, designed as a prestressed concrete continuous beam with a total length of 161.5 meters [1]. - The beam segment has a bottom width of 5.5 meters, a top width of 12.6 meters, and a height of 3.085 meters, with a total concrete volume exceeding 680 cubic meters [1]. - The first segment of the beam, measuring 22 meters in length, involved pouring 259 cubic meters of concrete using a full-support formwork method [1]. Group 2: Construction Techniques and Challenges - To ensure construction quality and safety, the project team has developed a scientific construction plan and conducted multiple expert reviews, optimizing the concrete mix and employing an intelligent temperature control system to monitor and manage temperature differences [2]. - Advanced techniques such as support formwork, stress monitoring, and intelligent tensioning and grouting have been utilized to enhance construction quality and stability [2]. Group 3: Strategic Importance - The Hefei-Wuhan High-Speed Railway is a crucial part of the "Eight Vertical and Eight Horizontal" high-speed rail network, connecting key regions in Anhui and Hubei provinces [2]. - Once operational, the railway will create a new high-speed rail corridor between Hefei and Wuhan, improving the railway network layout in the Yangtze River Economic Belt and facilitating regional development [2].
