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.

This invention relates to the field of trenchless pipeline repair engineering technology, specifically to an intelligent defect detection method for trenchless pipeline repair based on CCTV technology. The invention acquires structural data of pipeline defects using CCTV detection equipment. Based on the environmental compatibility priority of various standard raw material ratios of the curing agent, and integrating historical bonding and strength performance, the final ratio is selected. The analyzed curing agent thickness is applied to the fiber cloth, and the posture of the airbags binding the fiber cloth is dynamically adjusted. The current curing agent thickness is collected in real time to determine the airbag expansion state, achieving dynamic control of the airbag expansion state. This ensures precise alignment and adhesion between the fiber cloth and the pipeline defect area, improving the accuracy of trenchless pipeline repair construction. Simultaneously, based on the sealing and adhesion of the repair interface corresponding to the repaired defect area, the success of the pipeline repair is confirmed, preventing the use of substandard pipelines and reducing subsequent maintenance costs and failure rates.
