Corrugated steel guide plate structure and method capable of absorbing horizontal deformation in all-seamless bridge

Abstract

The invention relates to a corrugated steel guide plate structure capable of absorbing horizontal deformation in an all-seamless bridge. The structure comprises a bridge abutment, a wiring road surface, a sleeper beam, a support plate, a corrugated steel plate, an elastic joint filling layer and a surface layer, the wiring road surface and the corrugated steel plate are positioned on the support plate, and the surface layer is arranged on the wiring road surface and the corrugated steel plate. The corrugated steel plates and the elastic joint filling layers are used for meeting the requirementfor telescopic displacement of the seamless bridge, meanwhile, the effect of releasing the thermal expansion pressure stress of the cement concrete pavement is achieved, the deformation adapting capacity of the seamless bridge can be effectively enhanced, the driving comfort is improved, and the structure is suitable for an integrated seamless bridge with large longitudinal deformation.

Description

technical field [0001] The invention relates to a structure and method of a corrugated steel guide plate capable of absorbing horizontal deformation used in a fully seamless bridge. Background technique [0002] Bridge expansion joints are weak points in bridge structure design, and have become one of the difficult problems in bridge construction and maintenance. It is not only expensive but also requires long-term maintenance. Chinese designers and scholars have made a lot of valuable explorations on the mechanism, performance and materials of expansion joints, which have played a positive role in solving the problem of longitudinal deformation of bridges, but they cannot fundamentally solve the problem of fragile expansion joints. With the development of the economy and the increase of traffic pressure, the phenomenon of bridge expansion joint damage is becoming more and more serious, and the increase of maintenance cycle and maintenance cost is also increasing the pressur...

AI Technical Summary

Problems solved by technology

Improving the expansion device can only reduce the replacement cycle and damage degree of the expansion joint, but it cannot fundamentally solve the problem of maintenance and replacement of the expansion joint. The problems of difficult maintenance and high maintenance cost still exist, and the method of improving the expansion device can only treat the symptoms No permanent cure
