The invention belongs to road engineering bumping at bridge-head preventing and treating Treating technology field, it is related to a kind of composite pavement and bridge
The transition structure that connects and its construction technology.
Background technology
With the continuous improvement of road quality classification, in order to improve linear ride comfort, the structure such as bridge, culvert and passage
Build ratio also increasing.Due to traffic load and Gravitative Loads at the platform back of the body of these structures, cause the heavy of structure
The sedimentation of fall and the platform back of the body is inconsistent, thus leading to the vehicle run at high speed to pass through to produce the jump phenomena that jolts during road-bridge transition section.
Vehicle bump at bridge ends is also common problem in current highway construction, has had a strong impact on comfortableness and the safety of driving,
Reduce the travel speed of vehicle and the traffic capacity of road.Meanwhile, the unfavorable dynamic load that vehicle is produced by road-bridge transition section
And the effect of water-induced distress can accelerate the damage of abutment, bearing, expansion joint and pavement structure etc..
Generally using setting transition slab at bridge head, transition slab at bridge head near platform end majority is laid in the Treatment Methods of road-bridge transition section at present
The following or flat road surface substrate top surface of bituminous concrete surface layer, pressure transmission, on roadbed, adds rainwater from rank to vehicular load quickly
Ooze under the expansion joint at the place of connecing, cause filler soil erosion to make the excessive sedimentation of embankment, make brow plate emptying, attachment strap is changed into curved drawknot
Structure, comes to nothing and partly easily ftractures, and the secondary jump car phenomenon producing because attachment strap destroys is very universal, therefore there is presently no very
Effectively bumping at bridge-head Treatment Methods.

Contact, the bottom surface of oblique prestressed concrete plate is contacted with the upper surface of the upper surface of parados, the upper surface of bracket and basic unit,
Oblique prestressed concrete plate is stepped ramp type structure, and the upper surface of oblique prestressed concrete plate is equipped with the first bitumen layer, plate
The upper surface of beam is equipped with concrete layer and the second bitumen layer successively, and the end face of concrete layer is neat with the end face of the second bitumen layer
Flat, the first bitumen layer is flushed with the side on oblique prestressed concrete plate top, between the second bitumen layer and the first bitumen layer
It is reserved with expansion joint and stay groove；
Described back of the body coping is flushed with the top of bracket and the top of basic unit.
Also include some expansion joints embedded bar, one end of all expansion joints embedded bar is all embedded in oblique prestressing force and mixes
In concrete board, the other end all reaches outside the end face of oblique prestressed concrete plate, and each expansion joint embedded bar by length is
Two groups, in wherein first group, the length of each expansion joint embedded bar is 3m, and in second group, the length of each expansion joint embedded bar is
The expansion joint embedded bar in expansion joint embedded bar and second group in 4m, and first group alternates arrangement.
It is 6-7cm that the width of groove is stayed at described expansion joint.
Connected with the bridge construction technology of transition structure of composite pavement of the present invention is comprised the following steps:
1) process roadbed, and abutment of constructing, the structure of the thickness according to road surface structare layer and designed elevation acquisition parados, then
Construction parados and bracket on abutment, then in the top of roadbed construction basic unit, during construction, by bracket top, back of the body coping
And the top of basic unit pours and flushes；
2) plate-girder is set up on abutment, and in the oblique prestressed concrete plate of the top of parados, bracket and basic unit construction,
During construction, embedded expansion joint embedded bar in oblique prestressed concrete plate, simultaneously by the end of oblique prestressed concrete plate
Ledge structure is made in portion, stays groove, the width of described oblique prestressed concrete plate top bar and thickness according to stretching as expansion joint
Contracting seam stays the size of groove to determine；
3) in oblique prestressed concrete plate upper table surface construction the first bitumen layer, and plate-girder upper surface construct successively mixed
Solidifying soil layer and the second bitumen layer.
The method have the advantages that
Composite pavement of the present invention connect with bridge transition structure and preparation method thereof pass through oblique prestressing force mix
Concrete board replaces transition slab at bridge head, it is to avoid produce jump car phenomenon, oblique prestressed concrete plate simultaneously because transition slab at bridge head destroys
Share an expansion joint with plate-girder and stay groove, decrease the setting of seam at end of the bridge, be conducive to the draining at end of the bridge, alleviate water pair
Too low structural damage, does not need the size of oblique prestressed concrete plate is limited in laying, effectively alleviates
The effect of impact load at end of the bridge, and the impermeability of itself is good, the ability of resistance to deformation is strong, less demanding to roadbed, can
Bear the additional stress producing due to relative settlement, easy construction, be a kind of structure of good endurance, reduce maintenance
Cost, improves the service life of bridge structure.
