Abstract

The invention discloses a heat insulating type pipeline fixing support which comprises a bottom lining, a wall lining, an external barrel, piles and an internal barrel. The upward opening of the internal barrel is matched and fixedly connected with the outer wall of a supported pipeline. The bottom lining is paved in the bottom of the inner chamber of the external barrel, and the internal barrel inserted into the inner chamber of the external barrel is isolated by the bottom lining. The wall lining is arranged between the overlapped sections of the outer wall of the internal barrel and the inner wall of the external barrel. 4-8 piles are uniformly distributed and connected on the inner wall of the external barrel, the top ends of the vertically arranged piles are fixedly connected with the barrel opening of the external barrel to form a limiting structure of the pile, which can prevent the internal barrel from jumping upwards excessively, thus avoiding the accidents of stripping or malposition arrangement between the matched internal and external barrels. The heat insulating type pipeline fixing support is reasonable in heat insulating structure and remarkable in heat insulation effect, can greatly reduce heat energy loss of mated pipelines, and can create conditions for long-distance conveying of a heat medium of a heat supply network pipeline.
