A sealing profile made of rubber or rubber-like material for installation in a recess extending around concrete segments for a tunnel tube. The profile has on the base side a plurality of parallel grooves extending in the longitudinal direction, and parallel ducts extending in the longitudinal direction on the top side. The ducts are laterally displaced with respect to the grooves, and the back of the profile is substantially shaped with a plane surface. Of the three grooves provided on the base side, the center groove is from 10% to 20% deeper and wider than the adjacent grooves. In the center of the profile, the spacing between the ducts is larger than the spacing between the ducts disposed away from the center of the profile. The lateral sides of the profile are inclined at an angle of from 10 to 20 degrees.

A sealing profile formed of rubber or rubber-like material adapted to be inserted in a groove extending annularly in segments of a tunnel tube for sealing adjacent segments of the tunnel tube, said sealing profile comprising: (a) a planar base surface having three longitudinally extending, parallel, curved grooves therein, the middle one of said grooves being 10 to 20 percent deeper and wider than the adjacent grooves; (b) four parallel spaced apart ducts lying in a plane parallel to the base surface of said profile and laterally staggered with respect to said curved grooves, the middle two ducts disposed centrally in the profile having a greater spacing therebetween than the spacing between each one of said centrally disposed ducts and the outer duct adjacent thereto; (c) a maximum lateral width defined by a plane parallel to the planar base surface and disposed between the plane of the four ducts and the base surface; and, (d) lateral flanks extending from said base surface inclined at an angle from 10 to 20 degrees with respect to a plane perpendicular to said base surface; so that when respective sealing profiles in adjacent tunnel tube segments are pressed together, all sections of the profiles are evenly deformed and subjected to uniform stress throughout.
