Gas-phase anti-corrosion cable body and gas-phase anti-corrosion steel strand inhaul cable
The invention provides a gas-phase anti-corrosion cable body and a gas-phase anti-corrosion steel strand inhaul cable. The gas-phase anti-corrosion cable body comprises steel wires, a wrapping tape and a plastic sheath, a plurality of steel wires are twisted to form a steel strand, a plurality of steel strands are braided in a certain permutation and combination to form a cable strand, the wrapping tape is wound on the outer surface of the cable strand, and the plastic sheath is wound on the outer surface of the cable strand to form the gas-phase anti-corrosion steel strand inhaul cable. The outer surface of the wrapping tape is sleeved with the plastic sheath, the steel strands at the two ends are exposed outside, and a gas phase corrosion inhibition material is placed in the plastic sheath. The invention has the following beneficial effects: 1, the anticorrosion mechanism is clear, the technology is mature and reliable, the measures are simple and convenient, and the method is replaceable and convenient to implement; 2, steel wire damage or steel wire coating damage in the cable manufacturing process and corrosion prevention caused by wet air in the cable body can be naturally compensated; 3, inevitable corrosion conditions due to the characteristics of the structure can be improved, and full-section all-dimensional corrosion prevention can be achieved; and 4, on the basis of an existing inhaul cable body anti-corrosion technology, the anti-corrosion durability of the inhaul cable is prolonged through gas-phase corrosion inhibition and corrosion prevention.
本发明提供了一种气相防蚀索体及气相防蚀钢绞线拉索，该气相防蚀索体包括钢丝、包带、塑料护套，由多根钢丝捻绞制成钢绞线，将多束所述钢绞线以一定的排列组合进行编索形成索股，所述索股外表面缠绕所述包带，所述包带外表面套有所述塑料护套，两端的钢绞线裸露在外，所述塑料护套内放置有气相缓蚀材料。本发明的有益效果是：1、本发明防腐机理明确，技术成熟可靠，措施简便，可更换实施便捷；2、本发明能自然弥补在制索过程中钢丝损伤或钢丝镀层损伤及索体内部湿空气造成的防腐；3、本发明能改善因结构本身特点不可避免的存在的腐蚀条件，可达到全截面全方位防腐；4、在现有拉索索体防腐技术基础上通过气相缓蚀防腐再延长其防腐耐久性。
