The advantage is to protect pedestrians from some dangers or threats during construction, such as sparks or sand splashed during construction. Secondly, the enclosure surrounds the construction site, which reduces the noise pollution caused by the construction to the surrounding residents to a certain extent. Then the construction of enclosure baffle can enclose the road construction site, isolate the messy construction site from the charming urban environment, and protect the image in urban construction. Finally, on the baffle of the enclosure, you can also print and paste some blueprints of urban construction planning, or the construction of urban propaganda slogans, so that pedestrians can better understand and support urban road construction.
