Bridge pier body and arch ring reinforcing construction method

The invention relates to a bridge pier body and arch ring reinforcing construction method. According to the bridge pier body and arch ring reinforcing construction method, upper-section pier body outer wrapping concrete and arch ring sleeve arch concrete are poured synchronously, the age difference between an upper-section pier body outer wrapping concrete structure and an arch ring sleeve arch concrete structure is reduced, shrinkage creep of the concrete of the two structures is kept consistent, the number of shrinkage cracks of the concrete arch ring is effectively reduced, and the construction efficiency is improved. And the width and depth of the crack. The pier body outer wrapping concrete and the arch ring arch concrete are poured through self-compacting shrinkage-compensating concrete, polypropylene anti-crack fibers, an anti-segregation agent and an air entraining agent are added into the self-compacting shrinkage-compensating concrete, and on the premise that the concrete construction workability (t
