The convenient lifting aeration scheme has the characteristics of short construction period, low construction difficulty and no fire operation on site. The main and branch pipes on the pool surface are connected by flanges in sections, and the droop branch pipe is connected with the branch pipe through the nut of the removable flange. As long as the size of the pool and the positioning of the air duct are verified on site, the welding of each air distribution branch pipe is prefabricated in the factory, and the vertical branch pipe and the upper flange bolt are assembled after the pool is installed. At the scene only need to tighten the flange, nut, good expansion bolt fixed bracket, can not need large lifting equipment.
