Description

Technical Field

[0001] This utility model relates to the field of pipeline repair technology, specifically to a natural light curing device for trenchless pipeline repair. Background Technology

[0002] With urbanization, the construction of drainage pipelines increases annually, leading to a continuous rise in the number of underground pipe networks in cities. However, after years of operation, insufficient investment in maintenance and repair results in severe corrosion, leakage, damage, deformation, and uneven settlement. These pipelines are more susceptible to road collapses and pipe bursts when disturbed by external factors, causing significant economic losses and safety hazards. Replacing the entire pipeline with new ones is not only a massive undertaking but also costly and time-consuming. Therefore, to save costs, pipeline repair technologies are often used to extend the service life of pipelines. Trenchless pipeline repair technologies (such as CIPP curing pipeline repair technology and spray repair technology) repair the pipeline from within, avoiding ground excavation and reducing the amount of work, construction time, and environmental damage. Trenchless repair technologies have significant advantages, especially in old pipe networks, complex terrain, and areas with restricted construction. CIPP curing pipeline repair technology is a highly efficient trenchless repair technology. It involves installing a lining composed of fiber cloth, resin, and other materials inside the damaged pipeline, and then using curing technology to harden it into a new pipeline. This technology is widely used in the repair of pipelines such as sewage pipe networks, water supply pipe networks, and drainage pipe networks.

[0003] The existing technology has the following problems:

[0004] Existing trenchless pipeline repair curing devices commonly employ thermal curing and ultraviolet (UV) curing. Thermal curing, such as using steam or hot water for curing, often consumes a large amount of energy during pipeline repair and has a negative impact on the environment. Meanwhile, UV curing is not as environmentally friendly and fails to achieve optimal results, thus limiting its practical application. Utility Model Content
