Beschreibung
Zusammenfassung:	The invention discloses a vortex drainage-type noise reduction drainage pipe, which comprises a drainage pipe body. 6-18 guide spiral fins are connected with the inner wall of the drainage pipe body in a uniform distribution manner; each guide spiral fin is provided with a convex arc rebound surface and a concave arc interference surface; the spiral angle of each guide spiral fin is 3-12 degrees, and the spiral fins are 3-12mm wide, and 2-8.5mm high. The arc radius of each rebound surface is 3-12mm from the section view vertical to the normal cross section of the corresponding spiral fin; the arc radius of each interference surface is 7-22mm from the section view vertical to the normal cross section of the corresponding spiral fin. The invention also discloses a manufacturing method of the vortex drainage-type noise reduction drainage pipe. According to the vortex drainage-type noise reduction drainage pipe disclosed by the invention, the structure and the number of the internal spiral fins are optimized, and
