Description
Technical field
The utility model relates to traffic engineering Bridge subgrade settlement difference control technology field, is specifically related to pile framework groups of springs box-like bridge road transition section structure that is a kind of and abutment split.
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 problems to be solved in the utility model is to provide pile framework groups of springs box-like bridge road transition section structure that is a kind of and abutment split; This structure 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.The technical scheme that the utility model provides explains with bridge basement transition stage.
The utility model solves the problems of the technologies described above the technical scheme taked: a kind of pile framework groups of springs box-like bridge road transition section structure with abutment split, comprise ground, abutment, beam body and roadbed body, it is characterized in that: also comprise pile, reinforced concrete frame and spring bundle 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 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; Spring bundle is arranged between reinforced concrete prefabricated level board and reinforced concrete prefabricated tilt prop.
Steel corrugated sleeve pipe is set with outside spring bundle; The utility model use high-strength link bolt after precast rc slab and platform during pile and member integrated make.
Because the inclined-plane of frame construction and reinforced concrete prefabricated tilt prop are connected with roadbed body, roadbed body is that frame construction provides strong support; The transition region sedimentation of bridge road is effectively controlled by reinforced concrete frame.Be arranged on the steel corrugated sleeve pipe be set with outside spring bundle between reinforced concrete prefabricated level board and reinforced concrete prefabricated tilt prop and spring bundle, effectively alleviate action of traffic loading power.The utility model 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 steel concrete level board, reinforced concrete prefabricated tilt prop, spring Shu Yutai, pile forms a whole structure, effectively a traffic load part can be delivered to spring bundle from structure stress, a part is delivered to pile after platform, control the distortion of transition structure body, thus reduce the settlement difference between abutment and changeover portion; 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, the thickness of roadbed body 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) the triangle transition section structure that after platform, pile, reinforced concrete prefabricated level board and reinforced concrete prefabricated tilt prop form, forms a cavity, is provided with the spring bundle protected by corrugated bushing in 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, reduce the pressure to the roadbed body connected with it; Simultaneously 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) the utility model scope of application is comparatively wide, and construction quality is controlled.The triangle transition section structure that after platform, pile, reinforced concrete prefabricated level board and reinforced concrete prefabricated tilt prop form, is not only applicable to the transition between bridge road and roadbed, is suitable for and transition between tunnel and roadbed, between culvert and roadbed yet.
The predetermined level plate used due to the utility model and reinforced concrete prefabricated tilt prop are prefabrication and assembly construction, and the steel corrugated sleeve pipe of spring bundle and outside suit is also for install in advance; Effectively can control construction quality, overcome bridge road changeover portion construction quality in the past and be difficult to deficiency up to standard.
