A frame-type bridge-road transition section structure integrated with the bridge abutment

Abstract

The invention relates to the technical field of bridge subgrade settlement differences in traffic engineering, and in particular to a frame type bridge and road transition section structure connected with a bridge abutment into a whole. The frame type bridge and road transition section structure comprises the bridge abutment, a beam body and a subgrade body, and further comprises a reinforced concrete transition section frame. The reinforced concrete transition section frame structurally comprises a reinforced concrete precast horizontal plate and a reinforced concrete precast inclined supporting plate. The reinforced concrete precast horizontal plate is connected with the upper end of the bridge abutment through a first high-strength hinged bolt. The reinforced concrete precast inclined supporting plate is connected with the lower end of the bridge abutment through a second high-strength hinged bolt. The other end of the reinforced concrete precast horizontal plate is connected with the other end of the reinforced concrete precast inclined supporting plate through a third high-strength hinged bolt. The reinforced concrete precast inclined supporting plate is fixedly attached to the subgrade body. The reinforced concrete precast inclined supporting plate is connected with the subgrade body. The subgrade body provides powerful support for the reinforced concrete transition section frame, and settlement of the bridge and road transition section is effectively controlled.

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-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 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, tunnels, culve...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a frame-type bridge road transition section structure integrated with the bridge abutment, which can greatly reduce the settlement of the transition section and improve the overall stability of the transition section, so as to solve the problem that the existing technology cannot Settlement differences in transitional areas of bridges (or tunnels, culverts)
