Background

The CIPP reverse lining method, namely an in-situ curing method, originates from the great kingdom of the last 80 years, is the most widely used underground pipeline non-excavation repairing technology in the world so far, is suitable for the non-excavation repairing and renovation of gravity flow pipelines, pressure pipelines for water supply and drainage, gas, petrochemical industry and the like, and is rapidly and widely accepted due to the advantages of high construction speed, good pipe quality, small occupied area, small traffic influence, no disturbance to residents and the like. CIPP belongs to the technology of repairing an inner pipeline, and the principle of the CIPP is that a new lining is made inside an original pipeline, and the lining is heated, pressurized and cured through water, steam, light and the like to form a new pipeline, so that the CIPP has independent structural strength and can independently support external pressure and internal water pressure. At present, ultraviolet light curing is a novel repair technology, and the basic process is as follows: an ultraviolet glass fiber lining hose is dragged into the pipeline, and the resin is subjected to chemical reaction through ultraviolet UV irradiation, so that the resin is cured for about 2 to 4 hours. After the lining is solidified, a new continuous pipeline with full structural strength is formed in the original pipeline.

The corrosion resistance of the lining hose for repairing the traditional pipeline is poor, so that the lining hose is easy to corrode after being used for a long time to break and damage, the lining hose needs to be repeatedly repaired in a short time, and finally great trouble and inconvenience are brought to the repairing construction of the pipeline, so that the lining hose convenient for repairing the pipeline is needed.
