PCCP在南水北调工程中的施工与应用

Construction and Application of Prestressed Concrete Cylinder Pipe in the South-to-North Water Transfer Project

PCCP是近年研发出的一种新型复合材料管材,全称为预应力钢筒混凝土管,自内而外由高强混凝土管芯、钢筒、高强度预应力钢丝和砂浆保护层等部分组成,目前已在国家大型水利工程和市政引水工程中广泛使用。论文结合南水北调工程施工中的实际情况,对PCCP管道施工技术进行了应用与总结。

Prestressed Concrete Cylinder Pipe is a new type of composite material pipe developed in recent years.It is called prestressed steel cylinder concrete pipe.It is composed of high strength concrete pipe core,steel cylinder,high strength prestressed steel wire and mortar protective layer from inside to outside.At present,it has been widely used in national large-scale water conservancy projects and municipal water diversion projects.In this paper,the construction technology of prestressed concrete cylinder pipe is applied and summarized according to the actual situation of the south-to-north water transfer project.
