谈PCCP与PCP、钢管的比较

Comparison on PCCP Pipe,PCP Pipe and Steel Pipe

PCCP即“预应力钢筒混凝土管” ,它是一种大口径、高工压、长寿命的输水管道 ,在国外得到广泛的应用 ,在国内部分工程上也得到了应用 ,与我国目前常用的PCP、钢管、球墨铸铁管等输水管道相比 ,无论从结构形式、铺设工艺、工程造价 ,还是运行管理上比较 ,都具有十分明显的优越性。

In this paper,the PCCP pipe (the prestressed concrete cylinder pipe),a large diameter,high working pressure and long lifespan water conveyance pipe,is compared with the PCP pipe(prestressed concrete pipe)and the steel pipe from the sturctural type,layout technique,project cost,operation and management.The conclusion is that the PCCP pipe is of great advantages.
