Pile truss combined type bridge-road transition section structure independent of bridge abutment

Abstract

A pile truss combined type bridge-road transition section structure independent of a bridge abutment comprises a bridge abutment, a beam body, a roadbed body, a pile behind the bridge abutment, and a truss transition section structure. The pile behind the bridge abutment is disposed behind the bridge abutment. The truss transition section comprises a reinforced concrete horizontal plate, a reinforced concrete diagonal brace plate and a reinforced concrete truss member. The reinforced concrete horizontal plate is connected with the upper end of the pile behind the bridge abutment through hinging bolts, the reinforced concrete diagonal brace plate is connected with the lower end of the pile behind the bridge abutment through hinging bolts, and the other end of the reinforced concrete horizontal plate is connected with the other end of the reinforced concrete diagonal brace plate through hinging bolts. The reinforced concrete horizontal plate, the pile behind the bridge abutment and the reinforced concrete diagonal brace plate form a cavity, and the reinforced concrete truss member is mounted in the cavity. The reinforced concrete diagonal brace plate clings and is fixed to the roadbed body. Problem of settling difference caused by rigidity difference between abnormal structures in traffic lines can be solved by using the structure provided in the invention. The transition section structure between the pile behind the bridge abutment and the truss is suitable for transition between a tunnel culvert and the roadbed, too.

Description

Technical field [0001] The invention relates to the technical field of bridge settlement difference control in traffic engineering, in particular to a pile-column-truss combined bridge-road transition section structure independent of a bridge abutment. Background technique [0002] In the field of traffic engineering, whether it is a road or a railway, the problem of the transition section of the bridge (or tunnel, culvert) is like a stubborn 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 comfort of driving, reduces the speed of vehicles and the capacity of the road, and at the same time, as the settlement progresses further Increase, increase the damage to vehicles and abutment structures, and bring huge safety hazards to driving safety. [0003] For a traffic line composed of different structures such as bridges, t...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a pile truss combined bridge road transition section structure independent of the abutment; it can greatly reduce the settlement of the transition section and improve the overall stability of the transition section to solve the problem that the existing technology cannot Settlement differences in transitional areas of bridges (or tunnels, culverts)
