Intelligent rapid sealing and reinforcing device for highway bridge expansion joints and using method thereof

Abstract

The invention discloses an intelligent rapid sealing and reinforcing device for highway bridge expansion joints which comprises: a first layer protection structure which comprises oppositely-arrangedside concave protection grooves, wherein the opposite beam ends forming the expansion joint are sleeved with the first-layer protection structure; a sealing device which comprises a telescopic plate and air bags located at the top end and the bottom end of the telescopic plate, wherein the telescopic plate comprises connecting plates and a middle plate arranged between the connecting plates, the middle plate comprises rubber layers on the two sides and a steel plate arranged between the rubber layers, and a plurality of holes are formed in the rubber layers; a second-layer protection mechanismwhich comprises an arch plate arranged at the top end of the sealing device; an intelligent monitoring device which comprises a controller, an air bag monitoring module, a rubber layer fatigue agingmonitoring module and a positioning error reporting module. The intelligent rapid sealing and reinforcing device is simple in structure and rapid to install, and has good protection performance and sealing performance under the condition that the bridge deformation requirement is met.

Description

technical field [0001] The invention relates to the technical field of highway bridge construction, in particular to an intelligent rapid sealing reinforcement device for expansion joints of highway bridges and a method for using the same. Background technique [0002] Expansion joints of highway bridges refer to expansion joints that are usually set between two girder ends, between girder ends and abutments, or at the hinged position of the bridge in order to meet the deformation requirements of the bridge deck. The expansion joints are required to be parallel and perpendicular to the bridge axis Both directions can be freely expanded and contracted, firm and reliable. Expansion joints need to be equipped with expansion devices so that the vehicle should run smoothly without sudden jumps and noises, and it must be able to prevent rainwater and garbage from infiltrating and blocking; installation, inspection, maintenance, The removal of dirt must be simple and convenient.

[0002] Expansion joints of highway bridges refer to expansion joints that are usually set between two girder ends, between girder ends and abutments, or at the hinged position of the bridge in order to meet the deformation requirements of the bridge deck. Both directions can be freely expanded and contracted, firm and reliable. Expansion joints need to be equipped with expansion devices so that the vehicle should run smoothly without sudden jumps and noises, and it must be able to prevent rainwater and garbage from infiltrating and blocking; installation, inspection, maintenance, The removal of dirt must be simple and convenient. Once the telescopic device is damaged, it may seriously affect the speed, comfort and safety of driving, and even cause traffic safety accidents. The telescopic device in the prior art is not tightly sealed, and the construction is more cumbersome. and is not conducive to maintenance problems
