Sealing arrangement for tunnel segments

A sealing arrangement comprising:

• two abutting construction elements made of a material selected from the group consisting of concrete, steel, reinforced concrete, and cast iron, said construction elements comprising segments assembled into a tubular tunnel having transverse and longitudinal joints, each segment having at least one recess on its abutting side and extending all around and covering all abutting sides of the segment;
• a sealing section made of elastomer material and bridging the gap between two construction elements, said sealing section extending in the form of a strand located in each recess and forming a sealing frame with frame corners, wherein the sealing section is provided with open or closed flutes extending in the form of a strand and arranged on a section base side, and having at least two groups of ducts also extending in the form of strands and arranged between the flutes on a section face side, one group being located directly above the flutes and the other group being laterally offset with respect to the flutes,
• wherein both groups of ducts are substantially disposed in one plane extending parallel with the section base side or section face side, and wherein the cross-sectional shape of the ducts is substantially triangular with each duct having a point and a base, such that the points of the group of ducts located directly above the flutes face the section face side and the points of the group of ducts arranged laterally offset face the section base side, and wherein the bases of the group of ducts located directly above the flutes extend parallel with the section base side and wherein the triangle bases of the group of ducts arranged offset with respect to the flutes extend in a curved way.
