Description

Technical Field

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

[0002] Dust will be generated in construction sites and during construction processes such as urban municipal infrastructure construction, building construction and demolition, equipment installation projects, and decoration and repair projects. Dust is easily generated during the construction and upgrading of municipal roads, which affects passers-by and vehicles, and even affects the lives of surrounding residents. Therefore, construction fences will be built during the construction process. Construction fences refer to measures taken to isolate the construction site from the external environment and make the construction site a relatively closed space. Construction fences can not only protect the equipment on the construction site, but also beautify the internal and external environment of the construction, ensure the smooth progress of the construction project, and are also an important part of safe and civilized construction.

[0003] Common construction fences include walls built with various masonry materials and maintenance bodies made of various molded boards. However, existing masonry walls cannot be reused, and molded boards are usually cut into different sizes during installation, resulting in a low reuse rate of existing fence materials and causing material waste. In view of this, we provide a dust reduction fence for road construction. Utility Model Content
