technical field

The utility model relates to the field of steel box girder bridge construction, in particular to a steel bridge deck sandblasting and rust removal device for the construction of a steel box girder bridge.

Background technique

Steel box girder, also known as steel plate box girder, is a common structural form of long-span bridges. Generally used on bridges with large spans, it is called steel box girder because it looks like a box. Steel is a general term for iron-carbon alloys with a carbon content between 0.02% and 2.11% by mass. The chemical composition of steel can vary greatly. Steel containing only carbon elements is called carbon steel (carbon steel) or ordinary steel. Generally, the steel used for construction will rust on its surface after being exposed to the air for a period of time. If the rust removal is not carried out during the production time, it will seriously affect the toughness and strength of the steel; but the traditional steel bridge deck rust removal device will generate a large amount of rust dust and dust during work, which will pollute the air very much.
