Description

Technical Field

[0001] The utility model relates to the technical field of highway construction, and more specifically, to an environment-friendly dust removal device for highway construction. Background Art

[0002] During highway engineering construction, due to the loading and unloading of materials such as cement, concrete, asphalt, sand and gravel, as well as the vehicles passing by on the highway, dust is usually generated at the construction operation site during the material transportation and operation process. For the workers who are under construction, a large amount of dust will be inhaled, and the dust has great harm to the human body. At the same time, dust pollution is one of the important links in the treatment of air environmental pollution.

[0003] The patent with the authorization announcement number CN221131547U discloses an environment-friendly dust removal device for highway construction, including a base. A water tank is installed above the base. Two support rods are installed above the base. A cross bar is installed on each support rod. A plurality of atomizing nozzles are installed below the cross bar. An electric push rod is installed between the support rods. The technical solution of the utility model can move the dust removal device to the construction site during construction, and then start the electric push rod. The electric push rod can pull up the cross bar through a steel wire rope. At this time, the cross bar and the support rod are in a vertical state.
