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.
Claims20
A duct coupling system comprising:
- a first concrete segment;
- a first duct positioned in said first concrete segment so as to have an end extending outwardly therefrom;
- a second concrete segment;
- a second duct positioned in said second concrete segment so as to have an end extending outwardly therefrom in a direction toward the end of said first duct;
- and
- a tubular member slidably positioned over said ends of said first and second ducts so as to join said first and second ducts together in a liquid-tight relationship.
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 the tubular member 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 such that said tubular member is embedded therein.
A duct coupling system comprising:

- a second duct positioned in said second concrete segment so as to have an end extending outwardly therefrom and a direction toward the end of said first duct;
- a tubular member slidably positioned over the ends of said first and second ducts so as to join said first and second ducts together in a liquid-tight relationship;
- and
- a wet joint formed in a space between said first concrete segment and said second concrete segment, said tubular member being embedded in said wet joint.
