| 摘要 |
The present invention relates to a manufacturing method of a multi-walled sewer pipe for profile safety adhesion and, more specifically, to a manufacturing method of a multi-walled sewer pipe for profile safety adhesion, which enables to form safe adhesion and extend corrosion time. The present invention comprises: a profile extruder (100) for molding a profile (10); a first cooling device (100) for cooling the profile (10); a winding device (130) for winding the profile (10); a second cooling device (150) for cooling a multi-walled sewer pipe (30); and a cutting device (16) for cutting the multi-walled sewer pipe (30). The manufacturing apparatus comprises: a coating extruder (120) for coating the profile (10), and coating an interlinkage coating member (40); and an interlinkage member extrusion device (140) for coating an interlinkage adhesion member on the winding device (130). |
