The invention discloses a photoelectric water-gas double-pipe pipe rolling device. The cross section of water-gas double pipes is shown in the graph. The water-gas double pipes include the outer round pipe 112, the inner square pipe 113 and an electric wire 114 at the core portion. Water can be led between the outer round pipe 112 and the inner square pipe 113, and gas can be led between the inner square pipe 113 and the electric wire 114 at the core portion. Due to the fact that the external contour of the outer round pipe is round and the inner square pipe has certain buckling torsion rigidity, the pipes of the water-gas double pipes can be easily and flatly arranged in the pipe rolling device through an internal and external comprehensive effect, and the phenomenon that the pipes go to the upper row and are arranged disorderly when one column is not arranged full is not likely to happen. Due to the fact that gas can be led between the inner square pipe 113 and the electric wire 14 at the core portion, low-voltage electricity is used in the electric wire at the core portion, the electric wire 14 at the core portion is a bare wire, a layer of insulating materials are omitted, and cost is saved; a light wire is additionally arranged beside the electric wire at the core portion; and the water-gas double pipes include the outer round pipe 112 stretching and contracting in a wavy manner so that flexibility can be achieved.
