Abstract
In recent years,with the significant improvement of domestic transportation level,the construction of highways in various regions has developed rapidly in a network like manner.In the process of constructing a new transportation network,the renovation of existing roads is an unavoidable topic.The conventional demolition and reconstruction methods have limitations such as long construction period,high cost,and resource waste.Therefore,adopting the method of lifting and elevating the ground to renovate existing bridges can not only meet functional requirements but also reduce costs and improve efficiency.Based on Foshan Qingyuan Conghua Expressway Project,this paper explores the construction technology of synchronous lifting and elevation of prefabricated beam bridges crossing existing highways.The construction method is studied and analyzed in combination with the actual situation of the project,forming a scheme design and construction experience for lifting prefabricated beam bridges crossing highways,and promoting the development and progress of construction technology.关键词
