The utility model discloses an environment-friendly double-wall corrugated pipe for drainage, relates to the technical field of double-wall corrugated pipes, and aims to solve the problems that an existing environment-friendly corrugated pipe for drainage is poor in tensile effect, prone to deformation in the long-time use process, not good in corrosion resistance and heat insulation effect and not ideal in use effect. According to the scheme, the high-density polyethylene corrugated pipe comprises a high-density polyethylene corrugated outer pipe, an environment-friendly lining layer is arranged on the inner side of the high-density polyethylene corrugated outer pipe, the environment-friendly lining layer comprises a corrosion-resistant layer, a tensile layer is arranged on the outer side of the corrosion-resistant layer, and a heat insulation layer is arranged on the outer side of the tensile layer. A filling layer is arranged on the outer side of the heat insulation layer, and an insulating layer is arrang
