Pile column and framework combined bridge-road transition section structure separated from bridge abutment

Abstract

The invention relates to the technical field of bridge subgrade settlement difference control in traffic engineering, in particular to a pile column and framework combined bridge-road transition section structure separated from a bridge abutment. The pile column and framework combined bridge-road transition section structure comprises the bridge abutment, a beam body, a subgrade body, a pile column behind the abutment and a reinforced concrete framework, wherein the pile column behind the abutment is fixedly arranged behind the bridge abutment; the reinforced concrete framework comprises a reinforced concrete prefabricated horizontal plate and a reinforced concrete prefabricated diagonal bracing plate; the reinforced concrete prefabricated horizontal plate and the upper end of the pile column behind the abutment are connected by a first high-strength hinged bolt; the reinforced concrete prefabricated diagonal bracing plate and the lower part of the pile column behind the abutment are connected by a second high-strength hinged bolt; the other end of the reinforced concrete prefabricated horizontal plate and the other end of the reinforced concrete prefabricated diagonal bracing plate are connected by a third high-strength hinged bolt; the reinforced concrete prefabricated diagonal bracing plate is fixed on the subgrade body in an attaching manner; the settlement of a bridge-road transition area is effectively controlled by the reinforced concrete framework; the problem that settlement difference exists among special-shaped structures due to rigidity difference in a traffic line is solved.

Description

technical field [0001] The invention relates to the technical field of bridge embankment settlement difference control in traffic engineering, in particular to a pile frame combined bridge-road transition section structure separated from 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 structur...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a pile frame combined bridge transition section structure separated from the abutment; it 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 difference in bridge (or tunnel, culvert) road transition zone
