Abstract
A seamless bridge for road is composed of main beams, bridge piers, lap-jointed plates and sleeper beams, and features that said lap-jointed plate is connected between main beam and sleeper beam and one or more layers of earth material are spread on said lap-jointed plate.
Description
Technical field:
The invention belongs to the bridge field, be specifically related to the seamless bridge architecture advances.
Background technology:
In traditional medium and small bridge construction, be to adapt to the requirement of bridge construction distortion, must the long attachment strap of 4m-8m be set usually behind the platform between two beam-ends, between beam-ends and the abutment, the shrinkage joint is set.The purpose of attachment strap setting is the beam-ends that the faulting of slab ends discrepancy in elevation of platform dike joining place sudden change is distributed to attachment strap, to improve the driving situation of road-bridge transition section.Attachment strap separates fully with main beam structure, and near platform end is supported in behind the platform on bracket or the parados, and gradient is 0≤i%≤5%, and buried depth is divided into three kinds of ground type, half buried and deep embeded types, and wherein ground type is given for the rigid pavement.
In medium and small bridge, the standard practice of building monolithic (semi-monolithic formula) seamless bridge technology is: cancellation full-bridge shrinkage joint, comprise the shrinkage joint between once requisite beam-ends and the abutment, girder closely is connected with attachment strap (or claiming settlement plate), attachment strap (or claiming settlement plate) adopts the ground type setting, the gradient is concordant with road, with beam body dilatation, road joint is set to receive the distortion of bridge between attachment strap end and road pavement.
External seamless bridge design is owing to being provided with road joint, so still there is the shrinkage joint maintenance issues.
Summary of the invention:
Technical problem to be solved by this invention is at the deficiencies in the prior art, a kind of shrinkage joint of both having eliminated between beam-ends and the abutment is provided, eliminate the road joint between attachment strap end and the road pavement again, design and construction are convenient, be particularly suitable for medium and small bridge, the road and bridge that can reduce the bridge inspection and maintenance expense are completely without the seam bridge.
The present invention solves the problems of the technologies described above and adopts following technical scheme: a kind of road and bridge are completely without the seam bridge, comprise that girder, abutment (pier), attachment strap, sleeper beam, attachment strap near platform end closely are connected by main muscle with girder, the far platform end of attachment strap places on the sleeper beam, it is characterized in that attachment strap tilts with respect to the road surface, gradient i% is near platform end and the ratio of far platform end difference in height h with the attachment strap length l, promptly
Full duration is provided with single or multiple lift geotechnique material in above road surface of attachment strap or roadbed, and geotechnological material extends to beyond the attachment strap tail end.
The present invention has realized that fully full-bridge and road pavement are all seamless owing to take technique scheme, has really realized " zero dimension is protected ", has reduced maintenance cost; Owing to thoroughly solve the stretching device problem, improve the driving comfort of highway, improve durability of structures, social benefit is obvious; The present invention not only can be used for newly-built bridge construction, more can conveniently be used to exist the strengthening reconstruction work of the old bridge of abutment place stretching device problem, has wide range of applications.The present invention is specially adapted to medium and smallly stride footpath seamless bridge structure, and adopts the situation of bituminous concrete deck paving and bituminous concrete road pavement.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
The specific embodiment:
As shown in Figure 1, a kind of road and bridge are completely without the seam bridge, comprise that girder 1, abutment 2, attachment strap 3, sleeper beam 4, attachment strap near platform end closely are connected by main muscle 5 with girder, the far platform end of attachment strap places on the sleeper beam, it is characterized in that attachment strap tilts with respect to road surface 6, gradient i% is near platform end and the ratio of far platform end difference in height h with the attachment strap length l, promptly
Full duration is provided with single or multiple lift geotechnique material 7 in above road surface of attachment strap or roadbed, and geotechnological material extends to beyond the tail end again.
Show that by experiment described attachment strap gradient can be 0＜i%≤10%.
Among the present invention, attachment strap is out of shape with the beam body, and the beam body deformability is passed to behind the platform in the soil structures, and in above road surface of attachment strap or the road structure, full duration is provided with single or multiple lift geotechnique material will be out of shape absorption, effectively prevent the reflection crack of road pavement appearance.
Claims (2)
1, a kind of road and bridge are completely without the seam bridge, comprise that girder, abutment (pier), attachment strap, sleeper beam, attachment strap near platform end closely are connected by main muscle with girder, the far platform end of attachment strap places on the sleeper beam, it is characterized in that attachment strap tilts with respect to the road surface, gradient i% is near platform end and the ratio of far platform end difference in height h with the attachment strap length l, promptly
Full duration is provided with single or multiple lift geotechnique material in above road surface of attachment strap or roadbed, and geotechnological material extends to beyond the attachment strap tail end.
2, road and bridge according to claim 1 is characterized in that completely without the seam bridge described attachment strap gradient is 0＜i%≤10%.
