| Abstract: | The paper, based on No. 136 and No. 137 gate pier construction of Songjiang Bridge on Shanghai-Hangzhou pas- senger railway, introduces that the construction technology of gate pier capping beam over existing railway with the ＂工＂ style beam scaffolding construction technology. And it discusses the key control points of capping beam casting close to ex- isting railway and the structure underneath close to the catenafies, which can provide reference for casting construction over existing structure. |
