Concrete plastic composite pipe

The invention discloses a concrete plastic composite pipe, and belongs to the field of winding pipes. The concrete plastic composite pipe comprises a pipe body formed by spirally winding a prefabricated slab body, one or two or more through holes penetrating through the two ends are formed in the prefabricated slab body in the extending direction, the through holes are arranged in parallel, and one or two or more through holes are filled with concrete fillers. According to the technical scheme, after the pipe body is wound and formed by the prefabricated slab body, the prepared concrete filleris injected into the through holes; the concrete filler is condensed in the through holes to form one or more spiral support frameworks, so that the overall compressive strength of the pipe body canbe effectively improved; the concrete filler is used as a filling raw material, so that the manufacturing cost is low and the operation is convenient; meanwhile, the supporting rigidity of the concrete plastic composite pipe i
