Abstract

A prefabricated engineering pipe for municipal tap water comprises an engineering pipe body with a circular-ring-shaped section. The inner surface of the engineering pipe body is coated with a corrosion-resistant coating. A heat-preservation layer is located outside the engineering pipe body. A concrete shell is located on the outer surface of the heat-preservation layer, and the section of the concrete shell is trapezoidal. The outside of the concrete shell is coated with a corrosion-resistant coating. The outside of the concrete shell is coated with the corrosion-resistant coating, so that the corrosion resistance of the prefabricated engineering pipe is improved. The section of the concrete shell is trapezoidal, so that the mechanics requirement of the concrete shell in an underground soil layer is met.

Description

technical field [0001] The invention relates to a thermal insulation composite pipe, which belongs to the technical field of municipal pipelines. Background technique [0002] There are two types of building prefabricated piles currently used in China, concrete prefabricated piles, square piles and prestressed concrete pipe piles; steel piles. The processing technology of concrete prefabricated piles is relatively complicated, and there is a certain damage rate. Although its cost is low, its bearing capacity is relatively low.
