Full-Scale Prefabrication and Non-Destructive Quality Monitoring of Novel Bridge Substructure for “Pile-Column Integration”

The assembly process of “pile-column integration” is proposed in this study and applied the engineering with characteristics that most pile foundations are end-bearing piles, which conducive to returning normal operation transportation infrastructure a timely manner. From perspective practical application, bridge structure components, including column cap beam, reasonably designed prefabricated according requirements reconstruction expansion project old bridge. Through non-destructive testing technologies, concrete strength, cover thickness reinforcement, component size components monitored tested evaluate quality full-scale substructure for integration”. monitoring results showed strength by rebound method relatively stable. was higher than design their qualified rate 100%. According measured reinforcement electromagnetic induction fell within allowable range, rates were around 90%. could meet requirements. Although be 3-D point cloud scanning system, effect smaller still needs improved. substructures proved rationality prefabrication feasibility providing references application
