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. |
