Core Viewpoint - The construction of the Jianyang Tuojiang Grand Bridge is a key project in the Chengdu-Chongqing high-speed railway, which will significantly reduce travel time between Chengdu and Chongqing to 50 minutes upon completion [7][8]. Design and Engineering - The bridge features a main arch span of 320 meters and side arches of 72 meters, designed as a thrust-free composite arch bridge to accommodate geological conditions and navigation needs [8][9]. - The design process began in 2020, with the team opting for a thrust-free composite arch bridge over a cable-stayed bridge due to lower excavation volume, shorter construction time, and reduced costs [10][11]. Construction Techniques - The construction employs Building Information Modeling (BIM) and virtual assembly technology to enhance the efficiency of assembling the massive arch components [11][14]. - Each arch rib is composed of four steel pipes filled with concrete, with a length of 12 meters per rib, and the construction team utilizes digital scanning to ensure precision in assembly [11][12]. Quality Control - The project incorporates an intelligent bolt tightening system to ensure the correct torque is applied to approximately 72,000 high-strength bolts, preventing issues such as under-tightening or over-tightening [17][18]. - An intelligent temperature control system is also implemented to monitor and adjust the cooling of concrete during pouring, mitigating the risk of cracking due to temperature differentials [19]. Project Timeline - The Jianyang Tuojiang Grand Bridge is expected to be completed and ready for the first high-speed train service by the second half of this year [19].
