Pipeline maintenance can be divided into excavation-based maintenance and non-excavation-based maintenance, depending on whether excavation is required. Among them, ultraviolet light (UV) curing repair is a common non-digging repair technique that features good safety, minimal environmental impact, a short construction period, little disruption to traffic, and low overall social costs. UV-cured repair not only meets the technical and environmental requirements for modern pipeline repair, but it is also more suitable in terms of performance and cost, enabling the achievement of satisfactory repair results as expected. The UV-cured, non-excavation pipe repair technique involves using mechanical traction to pull a photosensitive glass fiber lining hose into the pipe that needs repair. Compressed air is then injected to expand the lining hose, causing it to fit tightly against the inner wall of the pipe. UV light is used to cure the glass fiber fabric within the lining hose, thereby forming a new pipe with a high-strength glass fiber lining. The process flow diagram for the UV-cured lining repair technique consists of 6 main stages: preparation for construction, pulling in the hose, installing the clamps, pulling in the light chain, curing the hose, and port treatment. Extension: CIPP belongs to pipeline repair technologies. The principle involves a non-woven fabric lining or glass fiber, with a polymer coating (PU or PE) applied on the outer layer; it is first impregnated with polyester resin or epoxy resin, and then pushed into sewers or sewage pipes using water gravity or compressed air, or it is pulled into the pipes (in the case of UV-cured glass fiber hoses). Once all the linings have been installed in the main pipeline, it is heated using water, steam, or ultraviolet UV light to trigger a chemical reaction in the resin, initiating its curing process; this takes approximately 4–8 hours. Once the lining is cured, a new, continuous pipe with full structural strength is formed within the original pipe.
