Description
Technical field
The utility model relates to a kind of eccentric steel work bridge pier bent cap that is positioned under the circular curve ramp bridge girder.
Background technology
In metropolitan city, between the main road of interchange viaduct, big multi-link circular curve ramp bridge.This ramp bridge is one with the 2-4 hole, and the top supporting member of each couplet is the Prestressed Continuous box-girder of one single box single chamber, the wide 3.5-4.5m of its underpart case, and the wide 8.0-9.0m of its end face carriageway plate, its deck profile grade is 1-3%.At the two ends of each couplet, adopt abutment or two-columned pier to support; At the middle part of each couplet, adopt the single-columned pier on drilled pile basis to support.At the top of abutment or two-columned pier, be equipped with a bent cap.At the end face of this bent cap, pasting two boards formula neoprene bearing side by side and supporting the ramp bridge girder.The single-columned pier pier stud is the Reinforced Concrete Circular Cylinder body that a diameter is 1400-1600mm, and it is located in the position, center of pier cap, and its end face is installed a pot bearing, to support the ramp bridge girder.
So-called circular curve ramp bridge, the longitudinal central axis line of its girder is one circular curve.Through this circular curve do one with the perpendicular circular arc camber of horizontal plane, this circular arc camber is the circular arc camber of this ramp bridge, its radius is 150-300m.The vertical axis of each single-columned pier pier stud of this ramp bridge all is positioned on this circular arc camber, and the center of gravity line of ramp bridge girder and the center of gravity line of wagon flow then are positioned at the circular arc camber 100-200mm place in addition of this ramp bridge.At the two ends of circular curve ramp bridge, at the end face of pier bent cap, the two boards formula neoprene bearing outside circular arc camber draws a straight line, and this straight line is the rotating shaft A of whole ramp bridge girder.In the outside of rotating shaft A, be the main body of ramp bridge girder, its weight accounts for the 70-90% of gross weight; In the inboard of rotating shaft A, be the part at ramp bridge girder two ends, its weight only accounts for the 30-10% of gross weight.
Under the long-term effect of eccentric vertical pressure and centrifugal force, in the outside of rotating shaft A, the main body of ramp bridge girder is sunk; In the inboard of rotating shaft A, the two ends of the ramp bridge girder warpage that makes progress.Meanwhile, whole ramp bridge girder produces translation to the outside of rotating shaft A.When the construction quality of ramp bridge was relatively poor, this kind phenomenon was with even more serious.Repair the circular curve ramp bridge, at first its girder is carried out translation, and then upwards prop up the top, make its girder return to the position of this bridge when just being completed.Under the girder of ramp bridge, make a pier stud off-centre in the outside of single-columned pier pier stud and add solid, make this pier stud become eight prisms of direction across bridge, to increase its bending resistance by cylinder.The vertical axis of whole pier stud to the outside of the circular arc camber of this ramp bridge translation 100-200mm, is formed an eccentric bridge pier pier stud.End face at this off-centre bridge pier pier stud adds an eccentric bridge pier bent cap, and the eccentricity pressure that support reaction that this eccentric bridge pier bent cap is provided and ramp bridge girder are applied matches.
The utility model is exactly to this above-mentioned conception and by the eccentric bridge pier bent cap of a kind of novel open side type of the meticulous development of the inventor.In the process of whole making, need not interruption of bridge deck traffic, need not to destroy greenery patches under the bridge, formed eccentric steel work bridge pier bent cap is handsome in appearance, and quality is firm, and can add integral body of solid and former bridge pier pier stud top formation with the pier stud off-centre of its below.
