Abstract

A sealing arrangement for shaft and tunnel constructions. The sealing of gaps between components of shaft and tunnel constructions is improved, in particular if the components are misaligned. For this purpose a) the sealing arrangement (1) comprises at least two components (2), which lie against each other at butt sides (3) so as to form a gap (4), b) the components (2) have an elastic sealing profile (5) on each butt side (3), and c) the sealing profiles (5) of the butt sides (3) that lie against each other lie against each other on a contact plane (6) and bridge the gap (4) in a sealing manner. The sealing profiles (5) have areas (7, 8) of different hardness arranged in alternation in the transverse direction (9) perpendicular to the respective profile longitudinal plane (10), the sealing profiles (5) of butt sides (3) that lie against each other differing from each other in the arrangement of the areas (7, 8) of different hardness in the transverse direction (9).
