High-amplitude strand group anchor inhaul cable

The utility model relates to a high-amplitude steel strand group anchor inhaul cable which is composed of clamping pieces, an anchor plate, a supporting cylinder, nuts, a connecting cylinder, a cable body, etc. The cable body comprises a plurality of steel strands to connect a horn sleeve cylinder between the anchor plate and the connecting cylinder. The mortar poured in the horn sleeve cylinder is wrapped with the steel strands which pass through a horn cylinder. The steel strands are clamped by the bondability which is produced by an anchoring unit which is composed of the clamping pieces and the anchor plate and the mortar poured in the horn sleeve cylinder. The fatigue load stress amplitude which the inhaul cable can sustain is 250MPa, and the anchoring performance is good under a low stress condition.
