南水北调工程管道供水的常见问题包括供水水源量少,无法高效保证正常供水;很多管道被引入工程或在通水、运行等几十年后,管道的防腐层开始出现破损点,且破损位置呈疏松的黑色锈层,使得管道的管壁厚度减薄,甚至出现大锈坑等,这些问题给南水北调正常供水带来极大的漏水隐患。为此,文章深入研究南水北调工程PCCP管道的应用,以某城市南水北调的PCCP管道施工为例,从设计的角度,探讨各种工艺设计的具体方法。
South-to-North Water Diversion Project Pipeline water supply, including the common problems of small water supply, can not effectively ensure the normal water supply; many pipe was introduced into the project or in the water, running and other decades, the pipeline began to appear damaged coating point, and the location of loosening Of the black rust layer, making the pipe wall thickness thinning, or even rust pits, these problems to the normal water supply in the South Water Diversion bring great leakage hazards. Therefore, the paper deeply studies the application of PCCP pipeline in South-to-North Water Diversion Project. Taking PCCP pipeline construction of a city in South-to-North Water Diversion as an example, this paper discusses various methods of process design from the perspective of design.
