Seal between concrete segments in tunnel construction has a sealing profile at the butting side with an embedded anchor foot in the segment and sets of longitudinal reinforcement filaments

摘要

A Sealing system is for use between two segments (1) of concrete or reinforced concretes and the like assembled into a tubular tunnel with longitudinal and lateral joints. Each segment is fitted with an elastomer sealing profile (7) at its butting side, with at least one anchor foot (5) durably fastened in the segment. A Sealing system is for use between two segments (1) of concrete or reinforced concretes and the like assembled into a tubular tunnel with longitudinal and lateral joints. Each segment is fitted with an elastomer sealing profile (7) at its butting side, with at least one anchor foot (5) durably fastened in the segment. The sealing profile has at least one embedded reinforcement (I) along the longitudinal profile line (X) at the profile butting side (3) and a second similar reinforcement (II) at the embedded anchor foot. The reinforcements are filaments (8, 9) of steel, carbon, plastics, or other high tensile low-stretch material, arranged symmetrically to the longitudinal center plane (Y) of the profile.
