Wall lead-through on a concrete vessel

摘要

Concrete vessels, for example separating vessels in sewerage technology, require wall lead-throughs which, depending on the application purpose, have to have different diameters and arrangements. This necessitates an extremely large number of components to be kept in stock. In order to reduce the number of types of vessels kept in stock, the vessels (1) have wall openings (2) for the insertion of insert discs (3), in which the actual lead-through openings (4) are arranged. For each nominal size, only one single type of vessel is thus necessary, it being possible, depending on the requirements, to adjust said vessel type to the given application purpose by means of different insert discs. <IMAGE>
