Abstract

See full text

A duct coupling system has a first concrete segment, a first duct positioned in the first concrete segment so as to have an end extending outwardly therefrom, a second concrete segment, a second duct positioned in the second concrete segment so as to have an end extending outwardly therefrom in a direction toward the end of the first duct, and a tubular member slidably positioned over the ends of the first and second ducts so as to join the first and second ducts together in a liquid-tight relationship. The first concrete segment is positioned in spaced relation to the second concrete segment. A wet joint is formed in the space between the first concrete segment and the second concrete segment. The tubular member is embedded in the wet joint.
