NOVELTY - The utility model claims a prefabricated directly-buried integrated insulating pipe with anti-corrosion function, comprising a pipeline main body, two groups of sealing component and an external protection component, the external protection component is sprayed on the outer surface of the pipeline main body, the plugging component is symmetrically sleeved on the two sides of the pipeline main body, and the plugging component is correspondingly set with the external protection component. The utility model realizes the strengthening of the anti-corrosion performance of the outer wall of the pipeline main body through the matching of the graphene-corrosion coating and the epoxy paint anti-corrosion coating, the inner and outer synchronous anti-corrosion treatment of the pipeline main body is realized, the utility model can be stably adapted in different working environments, at the same time, it is capable of preventing the pipeline main body from being fireproof, the waterproof performance is effectively improved, and under the cooperation of the blocking assembly, linkage circular ring the sealing sleeve to follow the movement, circular ring the sealing sleeve for external reinforcing sealing the pipeline joint, avoiding the connection leakage condition, further improving the anti-corrosion performance of the pipeline main body itself.
