TECHNICAL FIELD

[0001] The present application relates to the technical field of ultraviolet light curing pipeline repair equipment, in particular to a pipeline UV-CIPP repair quality real-time monitoring device and a monitoring method. BACKGROUND

[0002] In recent years, with the rapid development of urbanization in China, the construction scale of municipal drainage pipe network in China has been continuously increased. However, due to the congenital deficiency of the pipeline, non-standard construction and lack of maintenance in the later period, serious diseases such as corrosion, leakage, sedimentation, misalignment and scaling occur. If not maintained in time, once the pipeline fails, it will cause the road surface to collapse, seriously affecting the safety of people's life and property and the society.

[0003] The trenchless repair technology of the pipeline has been applied for a long time abroad, and has the advantages of low comprehensive cost, short construction period and small environmental impact, which can achieve the purpose of repairing the pipeline without affecting the operation of the city. The ultraviolet light in-situ curing repair (UV-CIPP) technology does not need to excavate earthwork, has the advantages of fast construction speed, short construction period, close adhesion of the inner lining pipe and the original pipeline, continuous inner lining pipe, high inner lining strength and smooth surface, and is widely used in trenchless repair of underground pipelines.

[0004] The ultraviolet light in-situ curing repair technology is to pull the glass fiber hose impregnated with resin from the deep well into the pipeline to be repaired, close the two ends of the hose and inflate it to make it tightly adhere to the inner wall of the pipeline to be repaired, then pull the ultraviolet light frame into the hose, and use the ultraviolet light frame to cure the hose. In short, it is a repair method that uses pulling method to place the hose into the original pipeline, and uses the ultraviolet light frame to form the inner lining of the pipeline after curing.

[0005] The ultraviolet light frame is provided with ultraviolet lamps for curing the hose, and the ultraviolet light frame is provided with wheels which can be passively walked in the pipeline under the action of traction. The ultraviolet light frame cures the hose while walking, until the repair of the entire pipeline is completed. However, the conventional ultraviolet light frame cannot monitor the pipeline repair in real time during the repair.

[0006] For the evaluation of the repair quality of UV-CIPP, the current "Urban Drainage Pipeline Trenchless Technology Construction and Acceptance Regulations" clearly states that the bending strength and compactness of the sample taken from the pipe opening are tested to evaluate the repair quality. However, this method is only limited to the evaluation of the repair quality of the cured pipe opening UV-CIPP, and cannot evaluate the repair quality of the intermediate part and the UV-CIPP during the curing process. Once the intermediate part of the pipeline has a weak curing zone, the repair quality of the UV-CIPP is seriously reduced, which affects the service life of the repaired pipeline and increases the maintenance cost of the pipeline.
