Frame and spring combination type bridge and road transition section structure integrated with bridge abutment

Abstract

The invention relates to a frame and spring combination type bridge and road transition section structure integrated with a bridge abutment. The frame and spring combination type bridge and road transition section structure comprises the bridge abutment, a beam and a subgrade body and further comprises a steel reinforced concrete transition section frame and a plurality of high-strength spring bundles. The steel reinforced concrete transition section frame comprises a prefabricated horizontal steel reinforced concrete plate and a prefabricated oblique steel reinforced concrete supporting plate. The prefabricated horizontal steel reinforced concrete plate is connected with the upper end of the bridge abutment through a first high-strength hinged bolt, the prefabricated oblique steel reinforced concrete supporting plate is connected with the lower end of the bridge abutment through a second high-strength hinged bolt, and the other end of the prefabricated horizontal steel reinforced concrete plate is connected with the other end of the prefabricated oblique steel reinforced concrete supporting plate through a third high-strength hinged bolt. The prefabricated oblique steel reinforced concrete supporting plate is fixedly attached to the subgrade body. The high-strength spring bundles are vertically installed between the prefabricated horizontal steel reinforced concrete plate and the prefabricated oblique steel reinforced concrete supporting plate. The frame and spring combination type bridge and road transition section structure solves the problem that a sedimentation difference is caused by a rigidity difference between special-shaped buildings in a transport line.

Description

technical field [0001] The invention relates to the technical field of bridge subgrade settlement difference control in traffic engineering, in particular to a frame-spring combined bridge-road transition section structure integrated with an abutment. Background technique [0002] In the field of traffic engineering, whether it is a highway or a railway, the problem of the bridge (or tunnel, culvert) road transition is like a persistent disease that recurs and cannot be completely cured. The "jumping" phenomenon at the bridge head caused by the settlement difference between the bridge abutment (tunnel entrance or culvert) and the roadbed seriously affects the driving comfort, reduces the vehicle speed and the traffic capacity of the road, and at the same time, with the settlement Further increase will increase the damage to vehicles and abutment structures, which will bring huge potential safety hazards to driving safety. [0003] For a traffic line composed of bridges, tun...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a frame-spring combined bridge transition section structure integrated with the abutment, which can greatly reduce the settlement of the transition section and improve the overall stability of the transition section to solve the existing Technology cannot radically solve the problem of settlement differences in bridge (or tunnel, culvert) road transition areas
