| Abstract: | In order to solve many construction technical problems of the middle span closure section of the rotating beam crossing the existing high-speed railway,the embedded steel shell construction technology at the end of the box girder is adopted.This paper discusses in detail the position relationship between the rotating beam and the existing line,the construction process of the middle span closure section,the hoisting of the steel shell of the closure section,the processing and production of the steel shell,the concrete pouring of the closure section and other key technologies,which solve the technical problems of the bridge crossing the existing line and the catenary construction,and accumulate rich construction experience in the construction of the existing railway line. |
| Keywords: | spanning high-speed rail rotating beam steel shell closure section construction technology |
