摘要

"Funnel-shaped water stopper" phenomenon: Refers to buiding stand pipe in normal gravity drainage, due to shape subtle changes of the inner wall of the local structure, so that the original shift to the center of the tube attached to the inner wall circumference circle in the water, forming a funnel shape flow phenomenon.This funnel-shaped water clog the exhaust channel in the pipeline at the riser normal drainage, causing water pressure fluctuations in the value of the inner tube and seal loss increases, lower riser drainage capacity.On the basis of the reasons a lot of experiments, on the construction of drainage systems "funnel-shaped water stopper phenomenon" of the system conditions and the impact of hazards and preventive measures can be taken and summarized for recommendation to manufacturers, designers and installation of staff caused by the necessary attention.
