The utility model discloses an intermediate layer type plastic conduit that prevents frostbite, including PVC inner structure layer, middle filling layer, PVC outer structural layer, its characterized in that along alternative a plurality of PVC support columns and a plurality of the PVC archs of being provided with of PVC inner structure layer circumference on the middle filling layer, support column and a plurality of archs with a PVC inner structure layer body coupling, the support column with it has the rock wool to fill between the bellied clearance, the outer periphery of support column is provided with the recess, be provided with the PVC lug rather than the looks adaptation in the recess, the lug with a PVC outer structural layer body coupling. The utility model discloses firm in connection between layer and the layer be difficult for leading to the fact the dislocation between layer and the layer, and pipeline compressive capacity is strong, and is not fragile. 本实用新型公开了种夹层防冻型塑料管道，包括PVC内结构层，中间填充层，PVC外
