                                 南水北調北京段zui長、zui復雜的大型輸水工程PCCP工程目前全面進入檢修期,預計將于7月底具備充水條件,以迎接汛后南水北調中線工程全線通水。

                              PCCP全名為預應力鋼筒混凝土管,是一種優 質的輸水管材,具有高強度、高壓力、高密封性的獨特性能。PCCP工程包括兩排內徑為4米的管道,起點為南水北調惠南莊泵站,終點為大寧調壓池,全長56.4公里,約占南水北調北京段總干渠全長70%.

                              據北京市南水北調辦公室介紹,南水北調中線工程南起丹江口水庫,經河南、河北,基本自流至北京,總干渠全長1276公里,一期工程年均調水95億立方米。PCCP工程于2008年4月建成,當年9月起通水運行。至今年3月,已累計從河北向北京應急調水16億立方米,為緩解北京嚴重缺水起到重要作用。今年汛后,江水即將進京,為達到大流量輸水要求,PCCP將由小流量輸水轉為泵站加壓輸水模式。

                              據介紹,該工程不僅是南水北調北京段zui長的大型輸水工程,還是我國目前采用PCCP管徑zui大、單節管道zui重的水利工程。其管道單節長5米,zui大重量達78噸。無論是設計、安裝還是運輸,在國內都無任何先例,對設計師和施工方來說,都是一個巨大挑戰。
