Description

Technical Field

[0001] The utility model relates to the field of construction engineering, and particularly relates to a dust reduction device for construction engineering. Background Technique

[0002] During the construction process of construction engineering, especially in operation links such as earth excavation, material stacking, and concrete pouring, a large amount of dust is often generated, which not only seriously pollutes the environment at the construction site and its surrounding areas, but also poses a threat to the health of construction workers.

[0003] The current dust reduction methods mainly rely on manual watering or using simple watering equipment, but these methods have many deficiencies. First of all, manual watering has low efficiency and is difficult to cover all dust sources, resulting in unsatisfactory dust reduction effects. Secondly, simple watering equipment often lacks flexibility and cannot be adjusted according to the specific conditions of the construction site, and cannot meet the complex and changeable dust reduction requirements. Content of the Utility Model
