云端坚守，我在空中“搭”大桥

Core Viewpoint - The construction of the Yongjiang Grand Bridge, a key project in the Hangzhou-Ningbo railway line, is progressing with a focus on the installation of steel beams, which is critical for the completion of the bridge before the typhoon season in June [1][4]. Group 1: Construction Process - The installation involves lifting steel beams weighing up to 80 tons to a height of 60 meters, requiring precise operations to avoid any errors [1][3]. - The steel beams are assembled using a modular construction technique, similar to "building blocks," consisting of multiple components that must be accurately positioned [1][3]. - The entire lifting and installation process takes approximately 8 hours, during which the operator must remain focused and cannot leave the control cabin [3]. Group 2: Project Significance - The Yongjiang Grand Bridge, measuring 1730 meters in length, is the last critical engineering component of the Hangzhou-Ningbo railway line and features the world's largest asymmetrical cable-stayed bridge span [3]. - The bridge's design accommodates the complex terrain of the Zhenhai Port area while ensuring that navigation along the Yongjiang River is not hindered [3]. Group 3: Workforce Commitment - Nearly 90 construction workers are dedicated to the project during the Spring Festival, showcasing their commitment and responsibility despite being away from their families [4]. - The workers' pride in contributing to a significant infrastructure project that benefits the public is highlighted, emphasizing the importance of their work [3][4].
