混凝土污水管的抗侵蚀寿命设计

Anticorrosion Life Expectancy Design for Concrete Sewer

预制混凝土污水管是世界各国污水系统中广为采用的材料,混凝土污水管的设计寿命是整个污水系统设计寿命的一个关键因素。根据混凝土污水管受污水侵蚀的机理及过程,在混凝土污水管的整体设计方案中,除了污水管的强度设计外,还必须进行混凝土污水管的抗侵蚀寿命设计,以保证整个污水系统的设计寿命。

Precast concrete sewers are widely utilized in the sanitary sewerage system all over the world. Guaranteeing the designed life expectancy of concrete sewers is one of key factors to ensure the whole sanitary sewerage system to operate safely. According to the mechanisms and the processes leading to corrosion of concrete sewers, in the design of the sewers, we should not only consider the design of the strength of the sewers, but also the design of its anticorrosion life expectancy, so as to guarantee the designed life expectancy of the whole sanitary sewerage system.
