Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction in building construction, in particular to a dust reduction device for public building construction. Background Art

[0002] Construction refers to production activities during the implementation phase of engineering construction. It is the process of building various types of buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. Construction is a technically complex production process that requires construction workers to use their ingenuity and creatively apply theories such as materials, mechanics, structures, and processes to solve technical problems that arise during construction and ensure project quality and construction safety. However, due to dry weather and the large number of construction machinery, a lot of dust will be generated, which not only pollutes the surrounding environment, but also endangers the health of personnel. Therefore, it is necessary to remove dust from construction sites.

[0003] The current dust suppression device for public building construction usually sprays water on the construction site, which can only suppress dust in a single direction, with a small dust suppression range and poor dust suppression effect. At the same time, during the dust suppression process, the height of the nozzle is fixed and cannot be effectively adjusted, making it difficult to spray over a large area, thereby limiting the dust removal range and resulting in low dust suppression efficiency. Therefore, we propose a dust suppression device for public building construction. Utility Model Content
