It is of high cost, late maintaining heavy workload, and it is present in existing road（To existing railway in high-voltage contact net）Top checks dimension
Repair the shortcomings such as difficulty.
Invention content
The purpose of this utility model is to provide a kind of cast-in-place balance swivel gate pier, avoids support cast-in-place concrete in situ
（Lid）Beam or steel（Lid）The deficiency of beam in the case where reducing to span line operation interference, reduces project cost.
Technical solution is used by the utility model：
A kind of cast-in-place balance swivel gate pier, it is characterised in that：
Including swivel pier stud and non-swivel pier stud；
Pier stud bottom is turned as pier stud basis, turns and is provided with Rotary ball hinge between pier stud and pier stud basis；
Non- swivel pier stud bottom is pier stud basis；
Bent cap is provided between the pier top of swivel pier stud and non-swivel pier stud, is passed through between non-swivel pier stud pier top and bent cap
Anchor cast-in-place entity section consolidation.
Swivel pier stud pier top is symmetrical with bent cap and is provided with counterweight beam section, and before swivel, bent cap and counterweight beam section are relative to turning
Body pier stud forms balanced structure.
Bent cap is integral cast-in-situ structure.
Counterweight beam section is formed by being segmented prefabricated section assembling.
Steel beam hole road is reserved in bent cap and is disposed with steel beam, steel beam includes permanent steel beam and temporary steel beam.
Steel beam hole road is reserved in counterweight beam section and is disposed with steel beam, steel beam is temporary steel beam.
On the inside of non-swivel pier stud gate pier falsework is provided between bent cap.
The utility model has the following advantages：
1st, using along gate pier span line direction mounting bracket Cast-in-place Bent Cap, rotator construction is balanced, design and construction are simple
It is convenient, the construction period above existing road is greatlyd save, it is minimum to existing road operation interference effect；
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 avoids Large-scale Hoisting equipment, due to using concrete structure, greatly reduces the later stage
Maintenance work and difficulty, save construction investment it is apparent.
For the utility model due to turning concrete structure using cast-in-place balance, design and construction are simple and convenient, can save the duration,
The most it is apparent that the influence to span line operation interference is minimum, the elevation of circuit is effectively reduced, saves construction investment, simultaneously
Greatly reduce maintenance work and the difficulty in later stage, more economical rationality again.
