SEGMENT TYPE COMPOSITE BOX GIRDER CONSTRUCTION METHOD

摘要

A segment type composite box girder construction method is provided to facilitate manufacture, transport and construction of composite box girder. A segment type composite box girder construction method comprises a step of connecting the adjacent ends of individual box girders(10) in the longitudinal direction, a step of forming a bottom plate on the top of the connected box girders to obtain an integral segment type composite box girder, a step of separating the integral segment type composite box girder into individual segment type composite box girders(100a), a step of transporting the individual segment type composite box girders to a construction site, a step of assembling the individual segment type composite box girders by using bolts before temporary installation, and a step of carrying out the construction of the assembled segment type composite box girders in the designated position by using a crane.
