[0002] Construction projects refer to the general term for various types of buildings and engineering facilities that provide the material and technical basis for human life and production. Construction projects are organized, purposeful, large-scale economic activities of human beings. According to their natural attributes, construction projects can be divided into three categories: architectural projects, civil engineering projects, and mechanical and electrical engineering projects. They are engineering projects that form comprehensive production capacity or exert engineering benefits in the process of fixed asset reproduction. Construction projects refer to the construction of new or the transformation of existing fixed assets. When carrying out construction projects, a large amount of dust will be generated on the construction site. The dust on the construction site will pollute the environment. The workers working there will inhale dusty air for a long time, which will endanger their health and pose a safety hazard.

Rotating columns 8 are rotatably installed at positions near the four corners inside the bottom plate 6. The top and bottom ends of the rotating columns 8 are flush with the upper and lower surfaces of the bottom plate 6 respectively. The vertical cross-section of the rotating column 8 is in the shape of a Chinese character 'zhong'. The rotating column 8 is coaxial with the sleeve 3, and the diameter of the rotating column 8 is smaller than the inner diameter of the sleeve 3. A vertical sliding hole 9 is coaxially formed through the inside of the rotating column 8. A roller frame 10 is slidably installed inside the vertical sliding hole 9. The roller 2 is rotatably installed at the bottom end of the roller frame 10. A handle 11 is fixedly installed at the top end of the first side plate 7.
