Abstract

The invention discloses a directly buried heating pipeline system with a corrosion-resistant heat-insulation function. The directly buried heating pipeline system with the corrosion-resistant heat-insulation function comprises a first heating pipeline, a second heating pipeline and heat-insulation shell pipeline, wherein the first heating pipeline and the second heating pipeline are arranged in the heat-insulation shell pipeline; sealing plates are respectively arranged at two ends of the heat-insulation shell pipeline; two small holes are formed in each sealing plate; the diameters of the two small holes of each sealing plate are the same as the diameter of the first heating pipeline and the diameter of the second heating pipeline; the first heating pipeline and the second heating pipeline can pass through each sealing plate through the two corresponding small holes separately; the heat-insulation shell pipeline further comprises an air inlet hole and an air outlet hole; the air inlet hole is formed in the upper end of the heat-insulation shell pipeline; the air outlet hole is formed in the lower end of the heat-insulation shell pipeline; the first heating pipeline and the second heating pipeline are arranged in the heat-insulation shell pipeline; and the heat-insulation shell pipeline is filled with hot air by the air inlet hole and the air outlet hole. The problem that the heating pipelines in the traditional directly buried pipeline system are in direct contact with soil to cause poor heating effect of the heating pipeline is solved.

Description

Technical field [0001] The invention relates to a pipeline protection system, in particular to a directly buried heating pipeline system with anticorrosion and heat preservation functions. Background technique [0002] The development of direct burying technology at home and abroad has a history of more than 60 years. Because direct burying pipelines have the characteristics of not affecting environmental beautification, gradual construction, short construction period, and low maintenance workload, especially in the past 30 years, direct hot water heating pipelines Buried laying has developed rapidly, and a set of design principles and calculation methods for direct buried laying have been formed accordingly. In the early 1980s, my country’s heating network projects in some cities used direct buried insulation pipes imported from Nordic countries for direct burial installation. After two decades of development, both in the production and installation technology of prefabricated i...
