Abstract
A grout vent for a tendon-receiving duct having a tubular fitting with an interior passageway, a nut secured around an exterior surface of the tubular fitting, and a seal extending around the tubular fitting and residing against a surface of the nut. The tubular fitting has a connector at an end thereof for engaging an interior surface of the duct. The tubular fitting extends through a hole formed in a corrugation of the duct so that a shoulder of the connector will abut an interior surface of a wall of the duct. The nut is threadedly engaged with an exterior surface of the tubular fitting so as to exert a compressive force against the seal. A grout line extends through the interior passageway of the tubular fitting so as to allow grout to be injected into an interior passageway of the duct.
Claims11
A tendon-receiving duct comprising:
- a tubular body having an interior passageway, said tubular body having a hole formed through a wall thereof, said tubular body having a plurality of corrugations extending radially outwardly therefrom, each of said plurality of corrugations being in spaced relationship to an adjacent corrugation, each of said plurality of corrugations opening to said interior passageway, said tubular body having a longitudinal channel extending between adjacent corrugations of said plurality of corrugations;
- a tubular fitting affixed through said hole so as to communicate with said interior passageway of said tubular body;
- and
- a seal extending around an exterior surface of said tubular fitting, said seal being in liquid-tight engagement against an exterior surface of said tubular body.
