Assembled box girder reinforcement cage and application thereof

The invention belongs to the technical field of civil engineering, and particularly relates to an assembled box girder reinforcement cage and application thereof. The invention provides an assembly type box girder reinforcement cage which comprises a standard reinforcement cage section and more than one insertion type reinforcement cage section, and the insertion type reinforcement cage section and the standard reinforcement cage section are connected and fixed according to a preset interval and a connection mode. The invention further provides application of the spliced box girder reinforcement cage in a prestressed concrete box girder. According to the assembled box girder steel reinforcement framework, only the framework needs to be connected during installation, field binding is not needed, the operation intensity is greatly reduced, and the working efficiency is greatly improved; the quality of the assembly structure is stable and controllable, the dependence on the on-site construction quality is reduce
