Specific embodiment
Below by drawings and examples, the utility model is described in further detail, but not as practical new to this
Any restrictions of type.
A kind of cast-in-place Continuous Box arch bridge of Long-span of the utility model, as depicted in figs. 1 and 2：Including
One group of bridge pier 3 and abutment 1 positioned at two sides；It is connected between bridge pier 3 and bridge pier 3 through box arch ring 2；By the bridge pier 3 and bank of offshore
The abutment 1 on side is connected through semiarch box circle 9；One group of upright post base 5 is equipped at the top of box arch ring 2 and semiarch box circle 9；Column
Pedestal 5 is equipped with one group of column 6；Column bent cap 7 is equipped at the top of column 6；The column bent cap 7 at each 6 top of column is through floorings 8
It is connected with each other；Column bent cap 7 by offshore is connect through floorings 8 with abutment 1.3 bottom of bridge pier is equipped with pile foundation support table 11, and pile foundation is held
On complete basement rock of 11 bottom of platform through 12 intrenched stream bottom of foundation pile.Abutment 1 is armored concrete entity structure, is located in the complete of bank
On integral basis rock.Box arch ring 2 and semiarch box circle 9 are armored concrete box section, and cross section type is single box single chamber, single case pair
Room or single-box multi-cell.Diaphragm plate 4 is equipped in box arch ring 2 and semiarch box circle 9, diaphragm plate 4 is along box arch ring 2 or half arch box
