Description
Technical field
The present invention relates to traffic engineering Bridge subgrade settlement difference control technology field, be specifically related to a kind of framework groups of springs box-like bridge road transition section structure linked into an integrated entity with abutment.
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 face 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 framework groups of springs box-like bridge road transition section structure linked into an integrated entity with abutment, it can reduce the sedimentation of changeover portion greatly, improve the resistance to overturning of changeover portion, bridge (or tunnel, culvert) road transition region settlement difference problem can not be effected a radical cure 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 as follows: a kind of framework groups of springs box-like bridge road transition section structure linked into an integrated entity with abutment, comprise abutment, beam body and roadbed body, it is characterized in that: also comprise steel concrete changeover portion framework and several high strong spring bundle; Reinforced concrete changeover portion soil framework 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 abutment upper end, reinforced concrete prefabricated tilt prop is connected by the second high-strength link bolt with abutment lower end, and the other end of reinforced concrete prefabricated level board 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; Vertically several high strong spring bundle is installed between reinforced concrete prefabricated level board and reinforced concrete prefabricated tilt prop.
Outside high strong spring bundle, corrugated bushing is installed.
High-strength link bolt used in the present invention, at precast rc slab and when building abutment and member integrated make.
The inclined-plane of steel concrete changeover portion framework, namely reinforced concrete prefabricated tilt prop and roadbed body are closely fixedly linked, roadbed body is that reinforced concrete frame structure provides powerful support, high strong spring bundle traffic load by time active force is cushioned, steel concrete changeover portion frame construction and the transition region sedimentation achieve effective control of high strong spring Shu Duiqiao road.The invention solves the problem occurring settlement difference in traffic route between special-shaped structure because of stiffness difference.Its advantage is compared with prior art:
1) steel concrete level board, steel concrete tilt prop and spring bundle and abutment are connected to form an overall statically determinate structrue, effectively a traffic load part can be passed to spring bundle from structure stress, a part is delivered to abutment itself, control the distortion of transition structure body, thus reduce the settlement difference between abutment and changeover portion; Steel concrete changeover portion frame construction is triangular structure, from abutment to roadbed direction, distance between steel concrete tilt prop and steel concrete level board reduces gradually, and the thickness of roadbed body below steel concrete tilt prop increases gradually, achieve the transition gradually between transition section structure and roadbed body, thus effectively prevent the generation of secondary settlement between transition section structure body and roadbed body.
2) this transition section structure is reinforced concrete frame structure, a cavity is formed in inside configuration, the high strong spring bundle of the vertical setting that cavity inside is installed is subject to corrugated bushing protection, 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; Simultaneously high strong spring Shu Benshen stores the load energy that a part of upper load transmits, and top traffic loading can be avoided to satisfy the need element body pressure, reduce the distortion of roadbed body, thus realize the smooth transition of bridge road sedimentation; Facilitate maintenance.
3) scope of application of the present invention is comparatively wide, and construction quality is controlled.The combination of steel concrete changeover portion framework and several high strong spring bundle is not only applicable to the transition between bridge road and roadbed, is applicable to the transition between tunnel and roadbed, between culvert and roadbed yet.The steel concrete level board used due to steel concrete changeover portion frame construction and steel concrete tilt prop are prefabrication and assembly construction, effectively can control construction quality, overcome bridge road changeover portion construction quality in the past and are difficult to deficiency up to standard.
