Description
Technical field
The present invention relates to traffic engineering Bridge subgrade settlement difference control technology field, be specifically related to a kind of with the pile of abutment split frame-combined bridge road transition section structure.
Background technology
In traffic engineering field, no matter be highway or railway, bridge (or tunnel, culvert) road changeover portion problem is just as one piece of persistent ailment recurrent exerbation and be difficult to thorough healing.End of the bridge " jumping car " phenomenon caused owing to there is settlement difference between abutment (tunnel or culvert) and roadbed, have a strong impact on the comfortableness of driving, reduce the traffic capacity of vehicle driving speed and road, simultaneously along with the further increase of sedimentation, strengthen the damage to vehicle and bridge abutment structure thing, bring huge potential safety hazard to traffic safety.
So to the traffic route be jointly made up of the different structure such as bridge, tunnel, culvert, roadbed and track, different structure influence each other and constitute smooth-going, a smooth circuit.In order to ensure its requirement that is smooth-going, smooth and comfortableness, the settlement difference along circuit longitudinal direction just strictly must be controlled, especially in tripe systems building joint.Owing to there are differences in the rigidity of structure between tripe systems building, in addition the difficulty that between the contact of tripe systems building, section exists when constructing, therefore, just settlement difference can be there is after construction between tripe systems building, structure different after circuit operation exacerbate settlement difference especially under the effect of traffic dynamic load, and particularly outstanding for the settlement difference of bridge (or tunnel, culvert) road changeover portion.
At present, at traffic engineering construction field, the measure that the settlement difference problem of administering bridge (or tunnel, culvert) road transition position is mainly taked has three: the first, measures of foundation treatment, mainly adopts cushion, reinforcing method etc. to process transition region soft foundation; Second arranges semi-rigid changeover portion, mainly selects high-quality, light filler fills transition region; 3rd, rebound method process transition region is set.Though these methods above-mentioned alleviate the excessive problem of transition region settlement difference to a certain extent, all can not tackle the problem at its root.
Summary of the invention
The technical problem that will solve of the present invention is to provide a kind of with the pile of abutment split frame-combined bridge road transition section structure; It can reduce the sedimentation of changeover portion greatly, improves the resistance to overturning of changeover portion, can not effect a radical cure bridge (or tunnel, culvert) road transition region settlement difference problem to solve prior art.Technical scheme provided by the invention explains with bridge basement transition stage.
The present invention's technical scheme taked that solves the problem is: a kind of with the pile of abutment split frame-combined bridge road transition section structure, comprises ground, abutment, beam body and roadbed body, it is characterized in that: also comprise pile and reinforced concrete frame after platform; After platform, pile is installed in after abutment, and reinforced concrete frame comprises reinforced concrete prefabricated level board and reinforced concrete prefabricated tilt prop; Reinforced concrete prefabricated level board is connected by the first high-strength link bolt with pile upper end after platform, reinforced concrete prefabricated tilt prop is connected by the second high-strength link bolt with pile bottom after platform, and the reinforced concrete prefabricated level board other end is connected by the strong link bolt of third high with the reinforced concrete prefabricated tilt prop other end; Roadbed body is fixed in reinforced concrete prefabricated tilt prop laminating.
Between abutment and roadbed body, bottom is provided with pile foundation, and after platform, pile bottom is arranged at pile foundation; Pile foundation provides effective support for pile after platform; High-strength link bolt used herein precast rc slab and after building platform during pile and member integrated make.
Roadbed body is fixed in the reinforced concrete prefabricated tilt prop laminating of the present invention; Namely reinforced concrete prefabricated tilt prop is connected with roadbed body, and roadbed body is that reinforced concrete frame provides strong support.The transition region sedimentation of bridge road is effectively controlled by reinforced concrete frame.The invention solves the technical problem occurring settlement difference in traffic route between special-shaped structure because of stiffness difference.Its advantage is compared with prior art:
1) after the steel concrete level board of changeover portion frame construction, tilt prop and platform, pile is connected to form an overall statically determinate structrue, can effectively part traffic loading be delivered on pile foundation by pile after platform from structure stress, thus control the distortion of transition structure body, and then reduce the settlement difference between abutment and changeover portion; After platform, pile, reinforced concrete prefabricated level board and reinforced concrete prefabricated tilt prop form stable triangle changeover portion frame construction, from pile after platform to roadbed direction, distance between steel concrete tilt prop and steel concrete level board reduces gradually, the thickness of roadbed body increases gradually, make to realize transition gradually between transition section structure and roadbed body, thus effectively prevent from, between transition section structure body and roadbed body, secondary settlement occurs.
2) the triangle changeover portion frame construction that after platform, pile, reinforced concrete prefabricated level board and reinforced concrete prefabricated tilt prop form, form a cavity, effectively can overcome entity transition section structure body in the past to conduct oneself with dignity excessive drawback, thus reduce transition section structure itself because of the sedimentation caused of conducting oneself with dignity; This transition section structure also reduces load pressure to the roadbed body contacted with it simultaneously, reduces the distortion of roadbed body, thus realizes the smooth transition of bridge road sedimentation; Be convenient to maintenance.
3) scope of application of the present invention is comparatively wide, and construction quality is controlled, is not only applicable to the transition between bridge road and roadbed, is also suitable for and between tunnel and roadbed, the transition between culvert and roadbed.Because predetermined level plate used in the present invention and reinforced concrete prefabricated tilt prop are prefabrication and assembly construction, effectively can control construction quality, overcome bridge road changeover portion construction quality in the past and be difficult to deficiency up to standard.
