A sealing arrangement includes face walls of two construction parts made of concrete, reinforced concrete or the like, these face walls being pressed against each other, particularly of tunnel tube segments, as well as a strand shaped seal made of elastomeric material for sealing the gap between the construction parts or tunnel tube segments, whereby the seal has a base part which, in relation to the sealing part, is widened on both sides, forming flanges, and which, by means of these flanges and suitable additional anchoring parts, is fastened on one of the two face walls of the construction parts or tunnel tube segments, whereas the sealing part, the latter being joined with the base part in one piece, has a trapezoidal shape, viewed cross-sectionally, and, in relation to the base part, a decreasing width, with lateral flanks tapering off at the same time, and seals the gap when the construction parts or tunnel tube segments are pressed together. In addition, there are at least two, particularly at least three ducts extending in the form of strands.

[ What is claimed is:] [1.]1. Sealing arrangement for tunnel tube segments comprisingface walls of two construction parts, said face walls being pressed together;a strand-shaped seal made of elastomeric material for sealing a gap between the construction parts;said seal has a sealing part and said seal has a base part which, in relation to the sealing part is widened on both sides, forming flanges and which, by means of said flanges and additional anchoring parts is fastened on one of the two face walls of the construction parts;said sealing part being joined with the base part as one piece, has a trapezoidal shape, viewed cross-sectionally, in relation to the base part with a decreasing width and lateral flanks tapering off at the same time, and sealing the gap when the construction parts are pressed together;at least two strand-shaped extending ducts are arranged within the trapezoidal sealing part;said sealing part having a longitudinal center plane (x);wherein the base part has a minimum width (a) of 300 mm;wherein the flanges of the base part have a minimum thickness (b) of 50 mm;wherein the flanges have a minimum stepping (c) of 40 mm;wherein the trapezoidal sealing part has a minimum height (d) of 250 mm;wherein the trapezoidal sealing part has a frontal surface having a substantially mirror-symmetric shape in relation to the longitudinal center plane (X);wherein the frontal surface has flute-type grooves or toothings;wherein said ducts are arranged one directly on top of the other exclusively in the center of the trapezoidal sealing part within the zone of the longitudinal center plane (X);wherein said ducts present are centered about the longitudinal center plane (X) of the frontal surface of the trapezoidal sealing part have a smaller diameter than ducts arranged beneath.
