Abstract

The invention relates to an intelligent prefabricated directly-buried insulating pipe steel pipe double-pipe crossing tee joint and a fixing method for alarm cables. At present, as no intelligent method is used for prefabricated directly-buried insulating pipes applied to the field of heat and cold supply or insulating pipe double-pipe crossing tee joints with steel pipes as working pipelines in China, breakage of the pipelines can not be found in time, dangerous cases can not be eliminated in time, a great deal of energy leaks, and energy consumption and pollution emission are increased. The intelligent prefabricated directly-buried insulating pipe steel pipe double-pipe crossing tee joint comprises a polyurethane insulating layer (1), a working steel pipe fitting A (5), a working steel pipe fitting B (6), a crossing working steel pipe fitting A (7), a crossing working steel pipe fitting B (8) and supports (3) are installed in the polyurethane insulating layer, the polyurethane insulating layer is connected with an outer protective pipe (2), and the supports are connected with the alarm cables (4). The fixing method is used for installing the pipeline alarm cables.

Description

Technical field: [0001] The invention relates to an intelligent prefabricated direct-buried thermal insulation steel pipe double-pipe fixing method across a three-way alarm line, which is applied to the energy transmission pipeline used in the field of heating and cooling—the intelligent prefabricated direct-buried thermal insulation steel pipe in the prefabricated direct-buried thermal insulation pipe The installation and fixing method of the alarm line in the double-pipe crossing tee fitting. Background technique: [0002] There is no intelligent method for the prefabricated direct-buried thermal insulation pipes currently used in the heating and cooling fields in China, and there is no intelligent method for the double-pipe spanning tee fittings of the thermal insulation pipe with steel pipes as the working pipeline, resulting in the failure of the pipeline to be detected and repaired in time. Excluding dangerous situations will cause a large amount of energy leakage, inc...
