Framework, truss and high-strength spring combined bridge-road transition section structure integrated with bridge abutment

Abstract

The invention discloses a framework, truss and high-strength spring combined bridge-road transition section structure integrated with a bridge abutment. The framework, truss and high-strength spring combined bridge-road transition section structure comprises a foundation, the bridge abutment, a beam body, a roadbed body, a framework transition section structure, a high-strength spring bundle and a reinforced concrete prefabricated truss member, wherein the framework transition section structure 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 bridge abutment are connected by a bolt; the reinforced concrete prefabricated diagonal bracing plate and the lower end of the bridge abutment are connected by the other 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 another bolt; a cavity is formed by the reinforced concrete prefabricated horizontal plate, the bridge abutment and the reinforced concrete prefabricated diagonal bracing plate; the reinforced concrete prefabricated truss member and the high-strength spring bundle are arranged in the cavity; the reinforced concrete prefabricated diagonal bracing plate is in contact with the roadbed body in an attaching manner; the roadbed body provides powerful support for a structure with a framework, a truss and a high-strength spring; the reinforced concrete prefabricated truss structure can be used for effectively controlling the settlement of a bridge-road transition area.

Description

technical field [0001] The invention relates to the technical field of differential control of subgrade settlement of bridges (or tunnels, culverts) in traffic engineering, in particular to a frame truss high-strength spring combined bridge-road transition 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, t...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a frame truss high-strength spring combined bridge transition section structure integrated with the abutment; it can greatly reduce the settlement of the transition section and improve the overall stability of the transition section, so as to solve the existing problems It cannot radically solve the problem of settlement difference in the subgrade transition area of ​​bridges (or tunnels, culverts)
