Rock-soil adaptive anti-corrosive anchorage cable

The utility model provides a rock-soil adaptive anti-corrosive anchorage cable which relates to a pre-stressing tendon anchoring body device, comprising an anchorage cable body and an outer anchor head composed of an anchoring device and an anchoring bottom plate. The anchorage cable body is a self adaptive anti-corrosive cable body comprises a bundling body (4) made of a steel strand bundle or a steel bundle and an inner protective layer or a winding and packeting belt, a PE outer sheath (6), an anticorrosion and lubricate buttering (5) arranged between the PE outer sheath and the bundling body. The thickness of strata with oil of the preservative lubricating oil perfused in the anticorrosion and lubricate buttering is between 0. 1 and 3 mm. The bundling body may be made by coating anticorrosion fat and oil outside the grain side steel strand bundle or the grain side steel bundle or by hot-pressing the PE guard pipe, and also may be made by mildly twisting the non agglutinate steel strand bundle, winding and packeting high intensity fabric polyester belt and then hot-pressing the PE guard pipe, even more may be made by combing the parallel non agglutinate steel strand and an inner support and then by winding and packeting the high intensity fabric polyester belt. The anchorage cable device is provided with stronger anti-shearing ability, strong adaptive ability and good anticorrosion property.
