  • Method and reel device for threading tendons into ducts
    Patent number: 9067757
    Abstract: A method is described for threading a tendon into a duct from an opening at an intermediate point along the length of the duct. Opposite ends of the tendon are threaded from a reel into the two halves of the duct. The tendon is wound on to the reel such that both ends of the tendon can be unwound into the duct simultaneously. A reel and a method for winding the tendon on to the reel are also claimed. The method and reel are particularly suitable for threading coated steel tendons into PT ducts in tall structures such as containment vessels.
