Sealing device for a manhole

摘要

This concerns a sealing device that ensures the hermetic securing of the lid (5) in the access mouth (2) in order to prevent any infiltration of fluids from the outside or escape of gases from the interior. It basically comprises a frame (1), a lid (5) that rests on said frame (1) with interposition of a sealing joint (6), and a crosspiece (12) in order to facilitate the securing of the lid (5) with the aid of a screw (21). The sealing joint (6) presents a special structure that permits complete imperviousness be obtained in the sealing of the device.
