Abstract

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.
