Bridge expansion joint alarm equipment for road engineering

Abstract

The invention belongs to the technical field of bridge expansion joint alarm and especially relates to bridge expansion joint alarm equipment for road engineering. The equipment comprises a bridge base surface. An outer side of the bridge base surface is fixedly connected with a fixing device; a bottom end of the fixing device is fixedly connected with a detection alarm device; a positioning plateis attached to a left side surface of a right bridge base surface; a communicating plate is simultaneously connected with two induction blocks in the same group; a distance between two bridge base surfaces can be monitored in real time; device bridge expansion joint monitoring and alarming are realized; and the bridge expansion joint is prevented from being too large to cause accidental dangers,the bridge expansion joint is prevented from being too small to enter a dangerous state, if the bridge expansion joint is too small, cooling operation or maintenance needs to be performed, the two bridge base surfaces are prevented from being abraded, the stability between the two bridge base surfaces is prevented from being affected, and using safety of the device is improved.

Description

technical field [0001] The invention belongs to the technical field of alarming bridge expansion joints, and in particular relates to an alarming device for bridge expansion joints used in road engineering. Background technique [0002] Bridge expansion joints: In order to meet the requirements of bridge deck deformation, expansion joints are usually set between two girder ends, between girder ends and abutments, or at the hinged position of the bridge. 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, the vehicle should run smoothly, without sudden jumps and noises, and should be able to prevent rainwater, garbage and soil from infiltrating and blocking; installation, inspection, maintenance, and removal of dirt should be simple and convenient. At the expansion joints, the railings and bridge deck pavement must be disconnected. [0003] Traditional bridge expansio...
