Japanese Patent JP2011147878
Kind Code:

Abstract:
To control stay of drainage occurring around a drainage outlet of water-area equipment.
Air within a drainage introduction pipe 26 flows into an expandable-and-contractible chamber 30 to expand a bag body 28, allowing the air within the drainage introduction pipe 26 to enter the expandable-and-contractible chamber 30. The drainage from water-area equipment 16 thus flows down through the drainage introduction pipe 26 at a nearly free falling speed, or flows down smoothly through the drainage introduction pipe 26, which can control stay of drainage around the drainage outlet 16A of the water-area equipment 16.
