In addition, there is also the use of a medium-tower stabilizer on the railway bridge for the first time in China. And it is the first adopt the method "whole segment erection", "first steel box girder construction, then the steel truss beam construction" and " steel truss beam construction after five internodes erection of steel box girder construction".
