PCCP管(Prestressed Concrete Cylinder Pipe)是预应力钢筒混凝土管的简称,是在带钢筒的混凝土管芯上缠绕预应力钢丝,并施喷水泥砂浆保护层而形成的复合型管道,是一种将钢管和预应力混凝土管相结合的新型管材。文章以河南省南水北调受水区供水配套工程许昌市境18号分水口门一标段为例,对PCCP管道从进场存放、安装、检验等关键工序施工工艺作了简要介绍。
PCCP pipe (Prestressed Concrete Cylinder Pipe) is the abbreviation of prestressed concrete cylinder pipe, concrete pipe with a steel tube wrapped around the prestressed steel wire, and the application of cement mortar protective layer formed composite pipe is a A new type of pipe that combines steel pipe with prestressed concrete pipe. Taking the No. 18 water gate project of Xuchang Urban Water Supply Area as an example, this paper briefly introduces the construction process of PCCP pipeline from the key process such as storage, installation and inspection.
