dam anchor reinforcement for multiple anti-corrosion cable and ground anchor tendon using it

摘要

PROBLEM TO BE SOLVED: To increase the reliability of the cutoff of a cable to be used for the reinforcement application of a concrete structure, and to prevent the intrusion of a corrosion factor to the inside by performing highly reliable cutoff even when a longitudinal anchor tendon is constituted.;SOLUTION: A plurality of tendons 2 each of which has been anticorrosion proofed are twisted and bundled into one, and a shaping material 3 for averaging the outer diameters of a cable is arranged across the full length of the cable between the adjacent tendons 2 in the outermost periphery, and a cutoff 4 filling a gap between the tendons and the surrounding gap of the shaping material 3 is arranged across a length range which is 300 mm or more in at least one end of the cable, and a sheath 6 made of synthetic resin, lubricant 7, and a second sheath 8 are arranged in the outer periphery of the flux of the tendons. The gap between the tendons and the surrounding gap of the shaping material may be packed with a packing material 5 across the full length of the cable instead of the cutoff 4.;COPYRIGHT: (C)2013,JPO&INPIT
