A steel-concrete composite segment of a steel-concrete hybrid girder features a complex structure and generally encounters difficulties in positioning and temporary fixation. In view of this, this study explored the layout of survey control networks and put forward a method for observing deformation of a concrete box girder at the cantilever end at the steel-concrete composite segment based on Hanzhuang Grand Canal Bridge, Tai’erzhuang District, Zaozhuang City, Shandong Province, China. Moreover, a construction process for hoisting the steel-concrete composite segment was proposed and a temporary fixation device for the segment used with a hanging basket was developed. The key sequences of temporary fixation were researched, which could provide practical and technological reference for similar engineering.
