Sliding and Incremental Launching Technology of Side Span Steel Box Girder of Qilu Yellow River Bridge
The upper steel box girder of Qilu Yellow River Bridge adopts the launching construction technology.Due to the construction boundary line and site terrain restrictions,a launching platform is set at the No.19 pier to complete the launching construction of the steel box girder with a main span of 420 m and a side span of 280 m,which affects the construction of the upper steel box girder of S95m span.According to the actual situation on site,a steel box girder sliding jacking technology is innovated and designed to install the S95m steel box girder.In this paper,the sliding incremental launching technology of side span steel box girder used in the Qilu Yellow River Bridge is described,which can provide reference for similar construction in the future.
