The Development of Prestressed Concrete Cylinder Pipe in China

Prestressed Concrete Cylinder Pipe (PCCP) consists of a steel cylinder lined with concrete, then helically wrapped with a wire and coated with a dense mortar. PCCP has excellent structural properties, so it is widely used in various water-transportation projects around world. This paper presents a review of development of PCCP in China, which was summarized as three stages: the period of exploratory development, the period of cooperativedevelopment, and the period of independent development. The development process of design and production technique, the application in China, the construction and development prospect of PCCP were made a detailed discussion in each stage.
