UV curing repair of pipelines

Overall CIPP UV curing repair of pipelines,Urban underground drainage pipelineAfter prolonged operation, various factors can cause varying degrees of damage and even lead to road collapse. In the past, damaged pipelines were often replaced by excavating the road surface. However, excavation and repair are time-consuming, costly, labor-intensive, have significant impacts on transportation and the environment, and incur high overall social costs

For example, if the pipeline is buried 4 meters deep and the underground pipelines crisscross, it belongs to a high-risk project with complex surrounding environment. If traditional excavation methods are used for repair, pile foundation support and well point dewatering are required, and road traffic is closed. The construction period is one month shorter, which will have a significant impact on the travel and daily life of surrounding residents. By using non excavation repair technology, the overall lining repair of a 50 meter long pipeline was completed in just one day, occupying only one lane during the operation, with minimal impact on road traffic, and the cost was only half of excavation repair.

CIPP-UV ultraviolet curing repair technology for in-situ lining of non excavation pipelines:

Non excavation repair technology refers to the technique of repairing and updating water supply and drainage pipelines using minimal or no excavation of the surface. According to the construction process, non excavation repair techniques include in-situ solidification method, pipe insertion method, coating method, and on-site pipe making method. This technology has CCTV monitoring throughout the construction process, good construction controllability, strong corrosion resistance, high strength, and long service life of the lining pipe.

　Detailed introduction of CIPP UV curing repair process:Drag the light curing material hose into the underground pipeline using a dragging method. Then, use a blower to inflate and spread the material, and place it into a UV lamp for light curing. After lighting up, move the ultraviolet lamp inside the pipeline at a certain speed. The irradiated material solidifies, forming a high-strength glass fiber lining inside the old pipeline.
