Description

Technical Field

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

[0002] Corrosion on the surface of steel structure bridges is usually one of the main causes of bridge damage. Therefore, regular cleaning of the bridge surface is essential to maintain the bridge in good condition. When cleaning, you can use a high-pressure water gun or chemical cleaning agent to remove dirt and corrosion on the bridge surface and restore the finish and corrosion resistance of the bridge surface. After cleaning, it should be dried in time to avoid moisture retention, which will lead to further development of corrosion.
