摘要
广州市西江引水工程输水干线主管材采用预应力钢筒混凝土管(PCCP)。为确保管道运行安全,采取提高水泥砂浆保护层质量、环氧煤沥青涂料外防腐、环氧饮水舱漆内防腐和聚硫密封膏接口密封防腐措施,提高了PCCP管的防腐能力,对类似工程具有借鉴意义。
Prestressed concrete cylinder pipe（ PCCP） is adopted as main pipes in the transmission pipeline of Guangzhou Xijiang River water diversion project. In order to ensure the safe operation of PC- CP, improving the quality of cement-mortar coating, external anticorrosion of epoxy coal asphalt coating, internal anticorrosion of epoxy drinking water cabin coating and joint sealing anticorrosion of polysulfide sealant were applied to increase the anticorrosion performance of PCCP. It can provide some reference for similar projects.
