The invention relates to the technical field of pipeline trenchless repair
engineering, and relates to a CCTV technology-based intelligent detection method for pipeline trenchless repair defects. Pipeline defect structure data are detected and obtained through CCTV detection equipment, a final proportion is screened according to the
environmental adaptation priority of standard
raw material proportions of curing agents and by fusing historical bonding performance and historical strength performance, the analyzed curing agent
coating thickness is smeared to
fiber cloth, the posture of an air bag for binding the
fiber cloth is dynamically adjusted, and the curing agent
coating quality is improved. The current curing agent thickness is collected in real time to judge the expansion state of the air bag,
dynamic management and control of the expansion state of the air bag are achieved, it is ensured that
fiber cloth and the defect area of the pipeline are precisely centered and attached, and the precision of non-excavation repairing construction of the pipeline is improved; and whether the pipeline repairing effect is qualified or not is determined, unqualified pipelines are prevented from being put into use, and the maintenance cost and the
fault occurrence rate of later operation and maintenance of the pipelines are reduced.
