Description
Technical field
The utility model relates to traffic engineering Bridge (or tunnel, culvert) subgrade settlement difference control technology field, is specifically related to a kind of framework rise of a truss strong spring modular bridge road transition section structure being specifically related to a kind of and abutment one.
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 framework rise of a truss strong spring modular bridge road transition section structure that is a kind of and abutment one; 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) roadbed transition region settlement difference problem to solve prior art.The technical scheme that the utility model provides explains with bridge roadbed interim form.
The utility model solves the problems of the technologies described above the technical scheme taked: a kind of framework rise of a truss strong spring modular bridge road transition section structure of the one with abutment, comprise ground, abutment, beam body and roadbed body, it is characterized in that: also comprise frame transitions segment structure, the high strong spring bundle vertically arranged and reinforced concrete prefabricated trussmember; Frame transitions segment structure 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 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; Reinforced concrete prefabricated level board, form cavity between abutment and reinforced concrete prefabricated tilt prop, reinforced concrete prefabricated trussmember is installed on cavity with the high strong spring bundle vertically arranged; Reinforced concrete prefabricated tilt prop laminating contact roadbed body.
The high strong spring bundle overcoat of vertical setting has steel corrugated sleeve pipe; Be connected by the 4th high-strength bolt between reinforced concrete prefabricated trussmember with reinforced concrete prefabricated level board, be connected by the 5th high-strength bolt between reinforced concrete prefabricated trussmember with reinforced concrete prefabricated tilt prop, reinforced concrete prefabricated trussmember is connected by the 6th high-strength bolt with between abutment.
Due to the inclined edge surfaces of frame transitions segment structure and reinforced concrete prefabricated tilt prop and roadbed body contacts, roadbed body is that framework+truss of the present utility model+high-strength spring assembly structure provides strong support; The transition region sedimentation of bridge road is effectively controlled by reinforced concrete truss structure.
The utility model is intended in transport solution circuit because the problem of settlement difference to appear in bridge (or tunnel, culvert) road changeover portion because of stiffness difference; Compared with prior art, major advantage is as follows for the utility model:
1, transition segment structure is the combining structure of framework+truss+high strong spring, steel concrete level board, tilt prop, truss, spring bundle and abutment are connected to form an overall structure, effectively traffic load part can be passed in truss and spring bundle from structure stress, part is delivered to abutment position, control the distortion of transition structure body, thus reduce the settlement difference between abutment and changeover portion; Changeover portion framework+truss+high-strength spring structure is overall 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, the transition gradually of rigidity between transition section structure and roadbed body can be realized, thus effectively prevent the generation of secondary settlement between transition section structure body and roadbed body.
2, transition segment structure is the combining structure of framework+truss+high strong spring, and they are connected to form indeterminate truss transition section structure body; Inside configuration is the spring bundle of truss and the vertical corrugated bushing protection arranged, and dead load reduces, and effectively can overcome entity transition section structure body in the past and to conduct oneself with dignity excessive drawback, thus reduces the sedimentation that transition section structure itself causes because of deadweight; Simultaneously truss+spring Shu Benshen bears and 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; Framework+truss+high strong spring transition section structure is not only applicable to the transition between bridge road and roadbed, is applicable between tunnel and roadbed, the transition between culvert and roadbed yet.The steel concrete level board used due to framework+truss+high strong spring transition section structure and 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 defect up to standard.
