Innovation and Application of Construction Technology for Urban Viaduct Cap Beams
With the development of urban transportation infrastructure,the construction of viaduct cap beams faces challenges such as elevated power lines and adverse weather conditions.The construction of supports uses composite steel plate beams and optimized de-signs of Bailey beams and steel pipe supports,reducing installation time by 33.33%and dismantling time by 50%.Formwork construc-tion achieves high precision and quick disassembly,ensuring quality and progress.Reinforcement construction combines prefabricated hoisting and segmented binding methods,increasing convenience and installation accuracy by 50%.Prestressed construction has im-proved the installation and tensioning technology of corrugated pipes,anchors,and steel strands,reducing tensioning time by 40%and increasing prestress transmission uniformity to 95%.Concrete construction uses high-performance mix design and new pouring and curing methods,reducing grouting time by 50%.By analyzing the case of the Tanzhou Express Phase I project in Zhongshan City,these technologies demonstrate improvements in quality and efficiency,ensuring safety and environmental protection.
