Research on the trestle erection technology of large-scale comprehensive transportation hub project
Taking the construction technique of the Dong Station East Road trestle in Chongqing as an example,this study explored the construction and installation technology of trestle erection.It comprehensively describes the steps including foundation casting,transportation and construction of steel tubular columns,pile cap treatment,single-piece truss support between columns,portal frame main beam installation,bearing longitudinal beam installation,pre-assembly and hoisting of bridge deck base plates,and construction of ancillary facilities,and finally,the construction verification was passed through standards and numerical simulation.The successful implementation of the construction of this trestle bridge pro-vides technical references and experience summaries for similar projects.
