中建新材护航甬舟铁路富翅门大桥主墩承台4300方混凝土浇筑成功

Core Viewpoint - The successful completion of the 20th main pier foundation of the YZ Railway Fu Chimen dual-use bridge marks a significant milestone in the construction of the bridge, which is the world's largest span of a high-low tower dual-use cable-stayed bridge [1][2]. Group 1: Project Challenges - The Fu Chimen dual-use bridge spans approximately 1725.85 meters with a main span of 388 meters, facing severe challenges due to a maximum water depth of 55 meters and complex marine environmental conditions such as strong winds, high waves, and turbulent water flows [2]. - The 20th main pier is a critical control project with a large foundation structure, complicated construction conditions, and high technical difficulty, which imposes strict requirements on concrete performance [2]. Group 2: New Material Solutions - The company leveraged its R&D advantages in concrete additives to create a tailored comprehensive solution, ensuring successful concrete pouring [3]. - Key features of the solution include precise temperature control to prevent cracking, extended plasticity to ensure smooth continuous pouring over 70 hours, and full-process technical services to dynamically optimize application parameters on-site [3]. Group 3: Recognition and Impact - The company's product performance, innovative technical solutions, and meticulous on-site service have earned high recognition from all parties involved in the project [4]. - The company's additives have also been successfully applied in several world-class projects, contributing significantly to the construction of major engineering projects, including the Hangzhou Bay Cross-Sea Railway Bridge and the Ningbo-Zhoushan integration development [4].
