Background
The fabricated simply-supported concrete bridge has the characteristics of reasonable stress, simple structure, quick construction, investment saving and the like, and is widely applied to bridge construction in China, particularly the fabricated small box girder, the T-shaped girder and the hollow slab girder are the most typical. The transverse connection of the small assembled concrete box girder and the main girder is realized through a longitudinal cast-in-place wet joint, and then the whole stress performance of the bridge structure is enhanced by means of an integrated layer and bridge pavement.
However, in recent years, due to continuous increase of traffic volume and long-term heavy-duty vehicle action, problems such as concrete cracking, water seepage, steel bar corrosion and the like occur in wet joints of bridges in operation, and in severe cases, longitudinal broken belts are formed at the joints. Damage to the longitudinal wet joints is a common problem for fabricated concrete box girders and main girder bridges, and the development of the damage will seriously affect the overall life and safe operation and normal use performance of the bridge structure.
At present, when the wet joint is seriously damaged, the wet joint needs to be dismantled and poured again, but the same problem may occur again after the newly poured wet joint is used for a period of time, so that a wet joint reinforcing device needs to be provided for reinforcing the wet joint, so that the performance of the wet joint is improved.
