Abstract

See full text

Apparatus allowing ventilation through a ventilation shaft to an underground ventilation duct fluidly communicating through the ventilation shaft to an atmospheric opening of the shaft and on threat of flooding operable to prevent downward flow of surface water into the underground ventilation duct includes one or more hinged panels closing a ventilation passage between the top and bottom of a support fitting in the shaft to prevent flooding. The panels have handles on their topside and pivotable arms on their underside and are liftable to an upright home position allowing ventilation, using tools to reach through grating covering openings on the shaft and lift the panel handles and after the panels are partially lifted, using reach tools to engage and lift the arms to press them again support sidewalls to exert lateral force on underside of the panels to complete upward rotation to the home position.
