Pipeline repairing method and reinforced pipeline

The invention discloses a pipeline repairing method and a reinforced pipeline, and belongs to the technical field of pipeline repairing. The pipeline repairing method comprises the steps that a to-be-repaired area of a target pipeline is subjected to surface treatment, and a pretreated to-be-repaired area is obtained; winding reinforcing fibers on the surface of the pretreated to-be-repaired area to form a reinforcing fiber layer; and in a vacuum environment, resin infiltrates the reinforced fiber layer, and after the resin is cured, the reinforced pipeline is obtained. When the resin infiltrates the reinforced fiber layer, a vacuum environment is provided, so that the resin can infiltrate the reinforced fiber more sufficiently and thoroughly, the defects of dry filaments, lack of glue and the like of the resin reinforced layer are reduced, the mechanical property and the sealing property of the resin reinforced layer are improved, and the influence of the construction environment on the repairing quality can
