Technical Field

[0001] The utility model relates to the technical field of directly buried heating pipelines, and more specifically, to a thermal insulation structure of directly buried heating pipelines. Background Art

[0002] During operation, heating pipes convey high-temperature liquids. These pipes are subject to temperature fluctuations both within the liquid and the surrounding environment, creating thermal stresses that can cause deformation.
