Outer wrapping type maintenance method for PE sheath of inhaul cable
The invention relates to the technical field of bridge engineering, in particular to an inhaul cable PE sheath wrapping type maintenance method. The inhaul cable PE sheath wrapping type maintenance method can be suitable for a cable-stayed bridge inhaul cable suspended at high altitude and an arch bridge horizontal cable placed on a bracket, the outer layer of the inhaul cable is reinforced and sealed in a local or overall wrapping mode, the sealing performance is reliable, the maintenance cost is low, and the inhaul cable PE sheath wrapping type maintenance method is different from traditional maintenance processes such as inhaul cable PE sheath hot melting repair and the like; the maintenance method has good durability and air tightness, can be suitable for severe working environments such as cable body vibration and pressure-bearing surface abrasion, can solve the problem that the service life of the inhaul cable is shorter than that of a full bridge due to the fact that the inhaul cable PE sheath is difficult to maintain for a long time, prolongs the service life of the inhaul cable, and has breakthrough significance on corrosion prevention and maintenance of the inhaul cable.
本发明涉及桥梁工程技术领域，具体涉及一种拉索PE护套外包式维修方法；本发明的拉索PE护套外包式维修方法能够适用于高空悬挂的斜拉桥拉索和搁置在托架上的拱桥水平索，采用局部或者整体外包的方式进行拉索外层加固和密闭，密封性能可靠，维修成本低，有别于传统拉索PE护套热熔修复等维修工艺，本维修方法具有良好的耐久性和气密性，能够适用于索体振动、承压面磨损等恶劣的工作环境，能够解决长期以来因拉索PE护套维修困难导致的拉索寿命期短于全桥寿命期的问题，增加拉索的使用寿命，对于拉索的防腐维修具有突破性意义。
