Description

Technical Field

[0001] The utility model relates to the technical field of dust suppression during highway construction, in particular to an assembled dust suppression device for highway construction. Background Art

[0002] The dust generated during the construction process contains particulate matter such as PM2.5 and PM10, which can easily spread through the air to form regional pollution, which not only aggravates smog weather, but also reduces air quality and affects the respiratory health of surrounding residents. Long-term exposure may cause diseases such as asthma and chronic bronchitis. At the same time, dust covering vegetation will hinder photosynthesis and destroy the ecological balance; particulate matter settling in the soil or water bodies may also cause heavy metal pollution, threatening agricultural production and drinking water safety. Implementing dust reduction measures such as fog cannon spraying, green net covering, and road hardening can not only reduce dust diffusion, but also enhance the company's environmental image, reduce the complaint rate of surrounding residents, and maintain social stability. In the long run, effectively controlling construction dust is an inevitable choice for achieving green infrastructure and promoting sustainable development. It is of great significance to building livable cities and ecological civilization.

[0003] Chinese patent publication number CN218608654U discloses a dust reduction device for highway construction. The device uses a motor to drive the spray mechanism and water bucket to rotate, expanding the spray range. The height adjustment mechanism is used to achieve targeted dust reduction at the construction site, providing convenience for dust reduction work at highway construction sites.

[0004] The above patent mainly relies on the nozzle to spray directly onto the construction site to achieve the purpose of dust reduction. However, the dust forms an accumulation layer on the ground of the highway construction site. The water mist can only combine with the surface of the dust accumulation layer, and there is still a large amount of dust at the bottom. There are problems such as incomplete dust reduction and dust is easily raised again. Therefore, it does not meet the existing needs, and an assembled dust reduction device for highway construction is proposed. Utility Model Content
