Manhole Aqua-Blok inflow protector |
摘要 |
An Aqua-Blok that fits into a frame or cone of a manhole directly beneath the cover, in the frame below the cover or within the cone to catch water that seeps into the manhole. Aqua-Blok is a polyurea, flexible bowl that rests on the frame directly under the cover or is mounted in frame or the cone. When used in the lower frame, it has a closed cell gasket on its outer top side, and an adjustable stainless steel ring on its inner circumference to press it against the frame. When Aqua-Blok is placed in the cone, it uses a rubber mount placed within the cone to mount Aqua-Blok. The rubber mount has a core with concentric rubber rings on its outer periphery that match the sloped sides of the cone. It has a circular cavity in its inner circumference to receive the pressure ring. The pressure ring forces the core and the concentric rings against the wall of the cone in a watertight fit. The bowl is seated on the mount where it catches any water that flows into the manhole from above it.
