Description

Technical Field

[0001] The utility model relates to the technical field of bridge engineering, in particular to a bridge maintenance structure. Background Art

[0002] Ancient bridges were mainly used for pedestrians and livestock, with a small load, and the longitudinal slope of the bridge deck could be steep, and even steps could be laid. Since the advent of railways, the loads borne by bridges have doubled, and the slope and curve standards of the lines have high requirements. In addition, a railway network needs to be built to increase economic benefits. Therefore, in order to cross larger and deeper rivers and canyons, bridges are forced to develop into larger spans. Bridge engineering has always been under the combined influence of production development and various scientific and technological advances, following the principles of applicability, safety, economy and beauty, and constantly moving forward. In order to increase the service life of bridges and ensure the safety of bridge use, it is particularly important to maintain the bridge after construction. In order to facilitate bridge maintenance operations, operators usually need to use various auxiliary tools.

[0003] For example, a bridge expansion joint cleaning device disclosed in the authorization announcement number CN210946477U includes a mobile frame, a dust bucket installed on the top of the mobile frame, and a cleaning head located at the front end of the dust bucket. The cleaning head includes a dust gun head and a vibrator. A vibrating sleeve is connected below the vibrator. The front end of the dust gun head is installed in the vibrating sleeve. The dust bucket includes a filter bucket and a dust suction fan. The rear end of the dust gun head is connected to the filter bucket through a dust suction pipe. A rubber sleeve is sleeved on the outer periphery of the bottom end of the vibration sleeve. The utility model is used for cleaning bridge expansion joints and has the advantages of high cleaning efficiency, good cleaning effect, simple structure and low manufacturing cost. However, the utility model lacks a dust blowing mechanism, which is not convenient for cleaning dust and impurities in the gap. For this reason, we propose a bridge maintenance structure, which adds a dust blowing mechanism during the maintenance operation of the bridge expansion joint, solves the problem of rapid cleaning of dust and impurities in the gap, improves the practicality and cleaning effect of the device, and thus more effectively maintains the expansion joint, reduces the probability of bridge deformation, and increases the service life of the bridge.
