Description

Technical Field

[0001] The utility model relates to the technical field of bridge expansion joint maintenance, in particular to a highway bridge expansion joint maintenance device. Background Art

[0002] Highway bridge expansion joint: refers to the expansion joint usually set between the two beam ends, between the beam end and the abutment, or at the hinged position of the bridge to meet the requirements of bridge deck deformation. The expansion joint is required to be able to freely expand and contract in both directions parallel and perpendicular to the bridge axis, be firm and reliable, and be smooth without sudden jumps and noise when vehicles pass by; it must be able to prevent rainwater and garbage and soil from infiltrating and blocking; installation, inspection, maintenance, and removal of dirt must be simple and convenient. At the expansion joint, the railing and the bridge deck pavement must be disconnected.

[0003] At present, in order to ensure that the functions of expansion joints of bridges are not affected during daily maintenance, it is usually necessary to regularly clean and maintain the gravel and soil in the expansion joints of bridges. Workers usually use a shovel to shovel up the gravel and soil in the expansion joints, and then use a vacuum cleaner for maintenance to reach into the expansion joints with a flat suction tube to suck away the remaining residual soil. However, the soil and gravel in the expansion joints have accumulated compactly for a long time. When cleaning the soil and gravel in the expansion joints, maintenance personnel often need to manually dig out the soil and gravel in the joints. The length of the expansion joints is usually long, which makes it inconvenient to clean and maintain the soil and gravel in the expansion joints. For this reason, we propose a maintenance device for highway bridge expansion joints. Utility Model Content
