A screw type multiple synthetic resin pipe is provided to improve production efficiency by feeding various profiles to an inner member and quickly forming the resin pipe, to enhance appearance by feeding a band type outer member to the outer side of the profile, and to simply transfer/manage/install the pipe by forming spaces at both sides of the profile. A screw type multiple synthetic resin pipe(30) spirally supplied to a winder unit after extruding/feeding/cooling a profile(32) comprises an inner member(31) formed like a thin band to be supplied spirally to the winder unit; the profile supplied to the outer side of an inner diameter pressing/connecting unit as a border of the inner member to form a space(34) between the inner member and the inner diameter pressing/connecting unit; an outer member(33) supplied to the outer side of the profile and formed like a thin band; and an outer diameter pressing/connecting unit, that is, a border of the outer member pressed by a pressing roller to integrally connect the inner member, the profile, and the outer member.
