Description

Technical Field

[0002] Construction engineering refers to the production activities during the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. During the construction process, a large amount of dust is often generated, and dust reduction devices are generally used to suppress the dust.

Due to the height limitation of the mobile vehicle itself, it will have a certain impact on the dust reduction effect. Therefore, it is necessary to propose a new solution to the above problem.
