Building engineering structure design and planning method based on BIM

The invention discloses a building engineering structure design and a planning method based on BIM, and relates to the field of building engineering. The building engineering structure design comprises an air pipe distribution wall body, and a support structure is fixedly arranged on the lower side of the air pipe distribution wall body along the pipeline layout. By setting up the building engineering structure design and the planning method based on BIM, an information integration and engineering information exchange and sharing platform is formed, the purpose of scientifically and efficiently managing a building engineering air pipe system is achieved, residual dust in an air pipe is monitored through a dust meter, and once the dust exceeds the standard, in order to avoid the danger of dust explosion, a driving gear is started to rotate forwards by a certain angle; and dust in the pipeline is removed through fan-shaped filter plates and a filter layer, meanwhile, nitrogen and gas in the pipeline space are m
