The structure of the heat preservation pipe includes: an inner corrugated pipe body and an outer corrugated pipe body. The inner wave crest of the inner corrugated pipe body is connected to the outer wave crest of the outer corrugated pipe body through an upper annular connection block, and the inner wave trough of the inner corrugated pipe body is connected to the inner wave trough of the outer corrugated pipe body through a lower annular connection block. Elastic foam is filled between the inner corrugated pipe body and the outer corrugated pipe body, and an annular semi-circular protrusion is arranged inside the inner wave crest of the inner corrugated pipe body.
