A combined truss-type bridge-road transition structure integrated with the abutment

Abstract

The invention discloses a combined truss type bridge-road transition section structure integrated with a bridge abutment. The combined truss type bridge-road transition section structure integrated with the bridge abutment comprises the bridge abutment, a beam body and a roadbed body. The combined truss type bridge-road transition section structure integrated with the bridge abutment further comprises a truss transition section structure. The truss transition section structure comprises a prefabricated reinforced concrete horizontal plate, a prefabricated reinforced concrete oblique supporting plate and prefabricated reinforced concrete truss components. The prefabricated reinforced concrete horizontal plate is connected with the upper end of the bridge abutment through a first high-strength hinging bolt. The prefabricated reinforced concrete oblique supporting plate is connected with the lower end of the bridge abutment through a second high-strength hinging bolt. The other end of the prefabricated reinforced concrete horizontal plate is connected with the other end of the prefabricated reinforced concrete oblique supporting plate through a third high-strength hinging bolt. A cavity is defined by the prefabricated reinforced concrete horizontal plate, the bridge abutment and the prefabricated reinforced concrete oblique supporting plate. The prefabricated reinforced concrete truss components are mounted in the cavity. The prefabricated reinforced concrete oblique supporting plate is attached and fixed to the roadbed body. The combined truss type bridge-road transition section structure integrated with the bridge abutment solves the problem that sinking differences are caused by rigidity differences between special-shaped structures in a traffic line, and a truss structure is effectively supported by the roadbed body.

Description

technical field [0001] The invention relates to the technical field of bridge subgrade settlement difference control in traffic engineering, in particular to a combined truss type 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 difference in settlement between the abutment (tunnel or culvert) and the roadbed seriously affects the driving comfort, reduces the vehicle speed and the traffic capacity of the road, and with the further settlement Increase, increase the damage to vehicles and abutment structures, and bring huge potential safety hazards to driving safety. [0003] For a traffic line composed of bridges, tunnels, culverts, roadbeds and other structure...
