摘 要:20世纪90年代,PCCP管道因其经济可靠得以引进推广,现已应用于北京市应急备用地下水源工程中,取得了良好的效益。因PCCP管道首次在北京市供水工程中应用,且没有国家标准,在设计过程中对相关技术问题进行了初步探讨。In the 90s of last century, the PCCP has been widely used in many fields for its economy and credibility. Now, it has been used in emergency and standby underground water source engineering of Beijing, and has gotten favorable performance. We just made a preliminary investigation on some technical problems related to the planning of the PCCP because it was used in Beijing for the first time and there was no relative National Standard.
