The invention discloses a sound-insulation and noise-reduction drainage pipe, comprising drainage pipe bodies and pipe connectors for fixed connection. Each drainage pipe body is composed of an outer pipe wall, a sound-absorbing pipe layer and an inner pipe wall arranged from outside to inside. The pipe connector includes a fixed bearing assembly and a pressing assembly mounted thereon. The fixed bearing assembly is provided with positioning columns matched with positioning cylinders. The pressing assembly comprises two threaded rods penetrating through the connecting cylinder, and gears, first arc plates and second arc plates are fixedly installed on the rod surfaces. Through dual structural optimization of pipe bodies and connectors, the drainage pipe achieves excellent sound insulation and shock absorption performance.
