Description
Technical field
The present invention relates to the construction of bridge pier upper cantilever arm bent cap.
Background technology
In bridge coping construction at present, its stress system type is a lot, such as girder steel method, Support Method, pre-embedded steel slab welding three
Dihedral bracing members method, Hold Hoop method etc..When the cantilever of bent cap is long, first-selected Support Method, conventional support force body in construction
System has two kinds: land full hall steel tubular scaffold with couplers, gate type steel pipe scaffold (support).
When construction area is positioned at the big location of people's vehicle flowrate, urban district, work progress must assure that the operation that is normally open to traffic, and tradition is full
Hall rack construction can not meet requirement.
In consideration of it, conventional support system uses gate type steel pipe scaffold and anchor ear suspension scaffold, gate type steel pipe scaffold is subject to
Power is clear and definite, technology maturation, but speed of application is slow, and the construction period is long, needs the most, there is quality, potential safety hazard big；Anchor ear hangs
Builder's jack, using existing pier footing as stress basis, saves the time again pouring basis；Stress column is put down with overhead bridge pier
Row is arranged, reduces and takies vehicles and pedestrians road, alleviates the traffic pressure that construction brings, but cantilever design system exists
The risk of stability is had in the case of high buttress.
