Sealing arrangement for shaft and tunnel constructions

摘要

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).

主权项

1. A tunnel or shaft construction composed of individual monolithic prefabricated components, the tunnel or shaft construction comprising at least a first component and a second component, wherein
a) said first and second components lies against each other with abutting sides, with the abutting sides thereby forming a joint, b) the first component has a first elastic sealing profile and the second component has a second elastic sealing profile, the first and second elastic sealing profiles being arranged on the abutting sides of the first and second components, c) the first and second elastic sealing profiles of the abutting sides lie against each other on a contact plane, thereby bridging the joint in a sealing manner, d) each of the elastic sealing profiles has regions of a first and a second hardness arranged alternately along the contact plane perpendicular to the respective profile longitudinal plane, the second hardness being different from the first hardness, e) the first and second elastic sealing profiles of the abutting sides lying against each other differ from each other in the arrangement of the regions of said first and second hardness along the contact plane perpendicular to the respective profile longitudinal plane, and f) the regions of the first and second hardness are arranged in such a manner that, when the first and second elastic sealing profiles are arranged without an offset, each region of the first elastic sealing profile having the first hardness in each case is opposite a region of the second elastic sealing profile with the second hardness, and does not overlap any region of the second elastic sealing profile having the first hardness, and each region of the first elastic sealing profile having the second hardness in each case is opposite a region of the second elastic sealing profile with the first hardness, and does not overlap any region of the second elastic sealing profile having the second hardness.
