Abstract
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.

A method of forming a wet joint between a first concrete segment and a second concrete segments, the method comprising:
- forming the first concrete segment with a first duct embedded therein such that said first duct has an end extending outwardly of one side of the first concrete segment;
- forming the second concrete segment with a second duct embedded therein such that said second duct has an end extending outwardly of one side of said second concrete segment;
- applying a tubular member over the end of said first duct;
- sliding longitudinally the tubular member from entirely over the end of the first duct toward the second duct such that the tubular member overlies the end of the first duct and overlies the end of the second duct;
- and
- forming a wet joint between the first and second concrete segments after sliding the tubular member such that said tubular member is embedded therein.
