The Chinese bridge component industry has accelerated its deep integration with traditional construction models in the past decade, achieving a systematic transformation from 'on-site pouring' to 'factory prefabrication+on-site assembly'. The industry is comprehensively promoting standardized design, modular production, and mechanized lifting. For example, the Dongguan Dongguan Expressway project has achieved fully assembled construction of piers, cover beams, and box beams, shortening the on-site construction period by 40%, reducing labor by 60%, and reducing construction waste by 70%. Intelligent manufacturing is deeply embedded in the production process, and China Railway Baoqiao has applied collaborative robots to achieve automatic welding of complex steel beam welds without programming, improving the stability of welding quality to 99.5%; Macheng Liangchang monitors the temperature and humidity of concrete in real time through AI+IoT system, with curing error controlled within ± 1 ℃, and defect rate reduced by more than 50%. BIM and digital twin technology run through the entire design, manufacturing, and construction chain. The Zangjiang Bridge project constructs a digital model for the entire lifecycle, achieving visualization of construction progress and precise risk prediction. Driven by policies such as 'Made in China 2025', 'Work Plan for Stable Growth in the Steel Industry', and the Zhejiang 'Transportation and Construction Industrialization Pilot', the industry has formed a new ecology of 'component commercialization, production standardization, and digital management', promoting the transition of bridge construction from labor-intensive to technology intensive, reducing unit costs by 15% -20%, and improving comprehensive efficiency by more than 35%.
