The utility model has the following advantages：
1st, Precast Concrete Segmental Bridges bent cap is installed using along gate pier span line direction, balances rotator construction, greatly save
It is the construction period above existing road, minimum to existing road operation interference effect, due to being constructed using Precast Concrete Segmental Bridges, more
It can guarantee construction quality, while can further save the construction period with pier stud parallel construction；
2nd, cast-in-place concrete stent and the protecting canopy frame above existing road are eliminated, building height can be reduced, effectively
Reduce the elevation of circuit；
3 and steel（Lid）Beam is compared, and due to using concrete structure, greatly reduces maintenance work and the hardly possible in later stage
It is apparent to save construction investment for degree.
The utility model is due to using section assembling balance swivel concrete structure, greatling save and being applied above existing road
The work duration, the influence to span line operation interference is minimum, and precast assembly ensures beam section quality, and parallel construction can be saved the duration,
The elevation of circuit is effectively reduced, saves construction investment, while greatly reduces maintenance work and the difficulty in later stage again, is more passed through
Ji is reasonable.
