[0002] Construction projects refer to all kinds of buildings and engineering facilities that provide material and technical basis for human life and production. Construction projects are organized, purposeful, and large-scale economic activities of human beings. According to their natural attributes, construction projects can be divided into three categories: architectural engineering, civil engineering, and electromechanical engineering. Noise will be generated during the construction process, which will have a negative impact on the surrounding residents. Construction fences are usually set up to enclose the construction site, which can reduce noise while preventing outsiders from mistakenly entering the construction site and causing accidents.
