Application of Coarse Aggregate UHPC Bridge Deck Retrofit Production Based on Ordinary Concrete Prefabricated Component Production Line
Based on the C150 coarse aggregate UHPC prefabricated bridge deck project of Wujiang Bridge on Deyu Expressway in Guizhou,based on the UHPC trial mixing and analysis of the existing ordinary concrete prefabricated component production line,the transformation measures for the prefabricated component production line are proposed.By transforming the ordinary concrete mixing station feeding system,concrete distribution and vibration system,prefabricated component maintenance system,the corresponding UHPC preparation process is proposed,so that the production line completes the automatic production of coarse aggregate UHPC bridge deck,reduces the production cost of UHPC and prefabricated components,and has a certain economy.
