TECHNICAL FIELD

[0002] The ultraviolet light in-situ curing method (UV-CIPP) is an advanced trenchless pipeline repair technology. The core advantage of light-cured pipe material is fast curing, controllable performance, adaptation to complex environments, and consideration of construction efficiency and environmental protection, which is an efficient and reliable solution in pipeline engineering. Different formulations of materials (such as epoxy acrylate and polyurethane acrylate) can adjust performance according to specific needs, further expanding the application range.
[0003] The ultraviolet light in-situ curing method places a flexible pipe material impregnated with light-cured resin into the original pipeline, tightly adheres it to the original pipeline, and then uses ultraviolet light to cure the hose, thereby forming an inner lining pipe to achieve the purpose of pipeline repair. Before the pipeline lining material is laid into the pipeline to be repaired, the lining material is in the form of a strip before curing, and the diameter of the strip is mostly close to the diameter of the manhole inlet. Therefore, the flexible pipe material needs to be folded and narrowed before being pulled into the pipeline to ensure that the pipe strip can be smoothly pulled into the pipeline to be repaired.
[0004] Currently, the folding method of the inner lining material mainly uses manual folding of the flexible pipe material. The width of the folded pipe strip is about one-third of the original width. However, due to the thickness of the flexible pipe material, a large amount of manpower is required to fold it simultaneously to ensure the folding efficiency, which seriously affects the work progress and increases the engineering cost.
