Abstract

China's railway prestressed concrete bridge has more than 600000 holes, prestressed engineering is a key force system affecting the safety and durability of the prestressed concrete bridge structure, its construction quality is easily affected by traditional manual operation technology, resulting in low construction efficiency and control accuracy, easy to form a hidden danger of quality and safety, it is difficult to meet the needs of less humanized, standardized intelligent construction trend. Based on the research on the intelligent prestressed construction control and testing technology and equipment for railway bridges, this paper proposes the integration of intelligent prestressed tension control and tunnel friction test of railway bridges, intelligent grouting control of tunnel and intelligent testing of beam construction quality, and sets up a complete technical system and integrated equipment for intelligent prestressed construction of bridges based on the industrial Internet of Things (IoT). Overall, improve the quality and efficiency of bridge production, construction, and management.
