The utility model relates to an enhancing thermoplastic composite structure wall tube, and comprises a plastic wall layer and spiral reinforcing ribs distributed on the outer surface of the plastic wall layer, reinforcing profiles are composited in the reinforcing ribs, and repair welding plastic coating layers which are arranged at two ends of the enhancing thermoplastic composite structure wall tube and coated on the reinforcing profiles exposed at the position of the reinforcing ribs. According to the enhancing thermoplastic composite structure wall tube, the fixed length is cut off, sharp edges of the cutting end face of the reinforcing ribs and the exposed reinforcing profiles are removed, the repair welding plastic coating layers are coated on the cut of the exposed reinforcing profiles after the sharp edges are removed, and the repair welding plastic coating layers can cover the exposed reinforcing profiles, so that corrosion of the reinforcing profiles caused by the contact with liquids inside the tube to influence the ring stiffness and normal use of the enhancing thermoplastic composite structure wall tube is avoided.
