Multi-stage prestressed finished anchorage cable

The utility model relates to a multi-stage prestressed finished anchorage cable comprising an inner anchorage section I, a free section II and an anchor head, characterized in that the inner anchorage section I consists of non-bond steel wire strands and 1-8 elliptic bearing components 8; the free section II an alignment frame 6, a non-bond steel wire strand bundle 5 covered with a PE layer or cased with a PVC hose and restriction rings 4 and 7; and the anchor head is an ordinary anchor head, or a sealed anchor head consisting of an airtight tube 11, an anchor plate 2, an anchorage and a protective cover 13; bond section 16 on one end of each non-bond steel wire strand 9 in the inner anchorage section I after removing PE is extruded into a P anchor by an extrusion sheath; epoxy resin 17 consolidates each P anchor, a bearing plate 14 and non-bond steel wire strands 9 into the elliptic bearing component 8; each non-bond steel wire strand of an anchor cable runs across the elliptic bearing components 8 and reaches the anchor head through the free section II. The anchor cable can be wholly manufactured within a factory and has the advantages of better anticorrosion performance, convenient construction and helping to guarantee construction quality.
