Novel integral bridge guide plate and construction method thereof

Abstract

The invention relates to a novel integral bridge guide plate and a construction method thereof. The novel integral bridge guide plate comprises a novel guide plate; a groove is formed downwards in theupper surface of the novel guide plate; a sliding layer is paved on the upper surface of the groove; a plurality of prefabricated concrete blocks are paved on a surface of the sliding layer; steel pipes are reserved in the prefabricated concrete blocks, and tension steel bars are arranged in the steel pipes in a penetrating mode; the left end of the novel guide plate is connected with a main beamthrough the tension steel bars, the lower end of the main beam is supported through a flexible bridge abutment, the bottom of the flexible bridge abutment and a pile foundation are fixedly arranged into a whole, and the novel integral bridge guide plate is reasonable in structure and can effectively prevent a road surface from cracking.

Description

technical field [0001] The invention relates to a novel integral bridge lead plate and a construction method thereof. Background technique [0002] Due to the cancellation of the expansion joints (or expansion devices) and supports of the integral bridge, the expansion and contraction caused by the longitudinal temperature deformation, shrinkage creep, and vehicle braking force deformation of the upper structure are mainly through the platform-soil interaction, pile-soil interaction and The joints between the board and the wiring surface can be absorbed by other methods. Compared with the slotted bridge, the integral bridge completely avoids the adverse effects of the expansion device and the fragile support on the bridge, can significantly improve the durability of the structure, improve the service quality and service life, and has excellent life-cycle economy . [0003] Under the action of temperature cycle, the integral bridge cannot be completely restored to its origi...

Problems solved by technology

[0003] Under the action of temperature cycle, the integral bridge cannot be completely restored to its original position due to the plasticity of the soil or the irrecoverability of the soil

Under such repeated actions, subsidence and voiding of the soil appear in the soil behind the abutment, resulting in the sinking of the guide plate and cracking of the slab body, which makes the bridge head more prone to "jumping" and aggravates the damage and destruction of the road behind the abutment
