The invention discloses a double-wall corrugated pipe manufacturing method. The double-wall corrugated pipe manufacturing method comprises the following steps that 1) inner wall pipe melt is mixed andstirred in a tank body, after mixing is finished, preheating is performed, outer wall pipe melt is mixed and stirred in the tank body of a stirring tank, and after the mixing is finished, preheatingis performed; 2) the inner wall pipe material and the outer wall pipe material which are obtained after mixing and preheating are finished are correspondingly put into a double-screw extruder for mixing extrusion and granulation; 3) obtained inner wall pipe particles and outer wall pipe particles undergo sealing storage at the environment of -5 DEG C to -15 DEG C; 4), the inner wall pipe particlesand the outer wall pipe particles obtained after refrigeration storage is finished are correspondingly heated again, after heating, inner wall melt and outer wall melt are formed; and 5) the inner wall melt and the outer wall melt are stretched, and are correspondingly extruded and cooled in an extruder, and the inner wall and the outer wall are connected together in a laminating mode to form a double-wall corrugated pipe. The double-wall corrugated pipe manufacturing method has the advantages that the steps are compact, the ring stiffness of the double-wall corrugated pipe can be effectivelyimproved, moreover, deformation is not prone to occurrence, and the usability is effectively improved.
