摘要

The closure is for a floor opening of a rainwater retention or waste water basin and involves a frame (3) extending around the opening and at least one pivotable cover (11) linked to the frame and swivelling around a horizontal axis (7). Also provided are a surrounding formation (17), a single or multi-part intermediate cover (19) extending over the entire cross-section of the floor opening and between the surrounding formation and the intermediate cover is an elastic sealing profile (21). The surrounding formation is formed on the frame or by an angular or Z-shaped profile section fixed to the cover of the basin.
