Abstract

A prefabricated pipe for a reclaimed water pipe network of a housing estate comprises a pipe body, wherein the cross section of the pipe body is circular-ring-shaped, the inner surface of the pipe body is coated with a corrosion resistance coating, the outside of the pipe body is an anti-freezing coating, the outer surface of the anti-freezing coating is a prefabricated insulating layer, the cross section of the prefabricated insulating layer is triangular, the outside of the prefabricated insulating layer is coated with a corrosion resistance coating, and the corrosion resistance coating improves the weather resisting performance of the prefabricated pipe for the reclaimed water pipe network. The triangular shape of the cross section of the prefabricated insulating layer meets the mechanical requirement of the prefabricated pipe in an underground soil layer.
