Construction Technology of Box Girder Erection Using Double Crane Lifting Method in Confined Space
This article relies on the Xiong'an New Area K1 Expressway(Phase I)Project under the Beijing Xiong'an Intercity Interchange.The preliminary planning,mid-term demonstration,and later verification of the construction method,equipment selection,foundation treatment,and safety control measures are carried out for the 30m simply supported box girder erection in the limited space section of the project,and through on-site in-vestigation,theoretical simulation,comparative analysis,literature review,and other methods,the construction process control data on the lifting method for box girder erection in the limited space section are summarized,providing reference for the formulation of similar construction plans and on-site organization in the future.
