Abstract: A pipeline support device for preventing melting and sinking based on gas heat exchange. The pipeline support device may be installed in a trench, and the pipeline support device may include a support frame and a gas heat exchange mechanism arranged on one side of the support frame. A bottom of the support frame may be fixed in the trench, a support partition may be fixed inside the support frame, the support partition separating the bottom of the support frame to form an upper chamber and a lower chamber. The gas heat exchange mechanism may include two groups of ventilation components, a group of air changing component and a group of control component. The control component may control opening and closing of ventilation openings of the ventilation pipes.
