Description

Oblique prestressed concrete composite pavement connects with bridge transition structure
Technical field
The utility model belongs to highway construction bumping at bridge-head control Treating technology field, relates to and to connect with bridge transition structure with the oblique prestressed concrete composite pavement of one.
Background technology
Along with improving constantly of road quality classification, in order to improve linear ride comfort, the ratio of building of the structures such as bridge, culvert and passage is also increasing.At the platform back of the body place of these structures due to traffic load and Gravitative Loads, cause the sedimentation of the sedimentation of structure and the platform back of the body inconsistent, thus cause the vehicle of running at high speed by producing chattering of jolting during road-bridge transition section.Vehicle bump at bridge ends is also ubiquitous problem in current highway construction, has had a strong impact on comfortableness and the safety of driving, has reduced the travel speed of vehicle and the traffic capacity of road.Meanwhile, the effect of the unfavorable dynamic load that produced by road-bridge transition section of vehicle and water-induced distress can accelerate the damage of abutment, bearing, shrinkage joint and road structure etc.
The Treatment Methods of current road-bridge transition section usually adopts and arranges transition slab at bridge head, transition slab at bridge head near platform end majority is laid in below bituminous concrete surface layer or flat road surface substrate top surface, the very fast pressure transmission of vehicular load is on roadbed, add that rainwater oozes from the shrinkage joint of joining place, cause filler soil erosion and make the excessive sedimentation of embankment, make brow plate emptying, attachment strap becomes curved pull-up structure, part of coming to nothing easily cracking, the secondary produced because attachment strap destroys jumps car phenomenon very generally, therefore does not also have highly effective bumping at bridge-head Treatment Methods at present.
Utility model content
The purpose of this utility model is the shortcoming overcoming above-mentioned prior art, and provide a kind of oblique prestressed concrete composite pavement and to connect with bridge transition structure, this transition structure effectively can prevent bumping at bridge-head, and long service life.
For achieving the above object, the oblique prestressed concrete composite pavement described in the utility model transition structure that connects with bridge comprises abutment, plate-girder, basic unit, parados, oblique prestressed concrete plate and roadbed;
Described roadbed contacts with the side of abutment, the top of abutment is located at by the end of plate-girder and parados, be reserved with shrinkage joint between the side of parados and the end of plate-girder and stay groove, the opposite side of parados is outward extended with bracket, the side of roadbed and the side of abutment, the side of parados and the bottom surface of bracket contact, basic unit is positioned on roadbed, and the outside of bracket contacts with the side of basic unit, the bottom surface of oblique prestressed concrete plate and the upper surface of parados, the upper surface of bracket and the upper surface of basic unit contact, oblique prestressed concrete plate is stepped ramp type structure, the upper surface of oblique prestressed concrete plate is equipped with the first bitumen layer, the upper surface of plate-girder is equipped with layer of concrete and the second bitumen layer successively, and the end face of the end face of layer of concrete and the second bitumen layer, the side on the first bitumen layer and oblique prestressed concrete plate top flushes, be reserved with shrinkage joint between second bitumen layer and the first bitumen layer and stay groove,
Described back of the body coping flushes with the top of bracket and the top of basic unit.
Also comprise some shrinkage joint embedded bar, one end of all shrinkage joint embedded bar is all embedded in oblique prestressed concrete plate, the other end all reaches outside the end face of oblique prestressed concrete plate, and each shrinkage joint embedded bar is two groups by length, wherein the length of each shrinkage joint embedded bar is 3m in first group, in second group, the length of each shrinkage joint embedded bar is 4m, and the shrinkage joint embedded bar in shrinkage joint embedded bar in first group and second group is alternately arranged mutually.
Described shrinkage joint stays the width of groove to be 6-7cm.
The utility model has following beneficial effect:
The oblique prestressed concrete composite pavement described in the utility model transition structure that connects with bridge replaces transition slab at bridge head by oblique prestressed concrete plate, avoid producing because transition slab at bridge head destroys jumping car phenomenon, oblique prestressed concrete plate and plate-girder share a shrinkage joint and stay groove simultaneously, decrease the setting of end of the bridge place seam, be conducive to the draining at end of the bridge place, alleviate water to too low structural damage, do not need to limit the size of oblique prestressed concrete plate when laying, effectively alleviate the effect of end of the bridge place impact load, and the impermeability of self is good, the ability of resistance to deformation is strong, less demanding to roadbed, the subsidiary stress because relative settlement produces can be born, easy construction, it is a kind of structure of good endurance, reduce the cost of maintenance, improve the application life of bridge construction.
