Abstract
There is provided a sealing profile formed of rubber or rubber-like material for tunnel segments having a recess therefor extending therearound, the profile having a base side facing the segment and a back side facing away from the segment, a plurality of longitudinally extending parallel flutes in the base side, lateral flanks extending angularly from the base side, a plurality of longitudinally extending parallel ducts, and at least one centrally disposed bridge through extending from the base side to the back side without impairment in its supporting effort by a longitudinal duct.

In a sealing profile formed of rubber or rubber-like material for tunnel segments having a recess therefor extending therearound, said profile having a base side facing said segment and a back side facing away from said segment, a plurality of longitudinally extending parallel flutes in said base side, lateral flanks extending angularly from said base side, and a plurality of longitudinally extending crossed-sectionally closed parallel ducts disposed above the base side, the improvement comprising said sealing profile including at least one centrally disposed bridge through extending from said base side to said back side without impairment in its supporting effect by a longitudinal duct, said at least one bridge being located only in the center region of said sealing profile so as to result the concentration of the force of reaction in said bridge and less stress relaxation therein during use.
