Abstract
A sealing arrangement (1) has two abutting construction elements made of concrete, steel, reinforced concrete, cast iron or other materials, as well as a sealing section made of an elastomer material which sealingly bridges the gap between the two construction elements. The construction elements are in particular segments (2, 2") which are assembled into a tubular tunnel with transverse and longitudinal joints (3). Each segment is preferably provided with a continuous groove on all its abutting sides. An elongated sealing profile (5) is located in each groove, forming a sealing frame with frame corners. The sealing section has elongated open and/or closed flutes arranged on the section base side and elongated ducts arranged between the flutes and the section front side. The sealing section (5) also has at least two groups (A, B) of ducts of which the first (A) is located directly above the flutes while the other (B) is laterally offset with respect to the flutes. Both groups (A, B) of ducts lie substantially in a plane parallel to the base or front side of the section.
