Abstract
A sealing profile made of rubber or rubber-like material, for sealing tubular tunnel segments provided with a recess extending therearound at their edges. The base surface of the profile has 4, 5, or 6 grooves extending parallel to each other in the longitudinal direction. Correspondingly, on top of the grooves are 3, 4, or 5 ducts, respectively, which are displaced sideways with respect to the grooves. The ducts also extend parallel in the longitudinal direction of the profile. The base surface of the profile has a plane surface and the grooves are identically shaped and arranged with equal spacings between each other. The ducts disposed above the grooves also have the same spacing between each other. The wall thickness of the profile is nearly everywhere equal, and the lateral sides of the profile are inclined with an angle of 10.degree. to 20.degree..
