随着我国对水资源的调整和分配,长距离引调水工程逐年增多。我国引进了大量的新型管材和新的生产工艺,为供水工程管材的选择提供了更多的余地。PCCP是近几年在供水工程中采用较多的新兴管材,本文以PCCP管材在河南省南水北调中线配套工程中的应用为例,从PCCP管材的结构组成、受力特性、设计成果以及施工安装技术要求等方面详细介绍其特点,为同类工程应用该种管材提供参考。
With the adjustment and distribution of water resources in our country, the long-distance diversion project has been increasing year by year. China introduced a large number of new pipe and new production technology, providing more room for the choice of water supply pipe. PCCP is an emerging pipe material used in water supply project in recent years. Taking PCCP pipe in the midline auxiliary project of South-to-North Water Diversion Project in Henan Province as an example, from the PCCP pipe’s structural composition, force characteristics, design results and construction and installation technology Requirements and other aspects of its characteristics, for similar projects to provide such a reference pipe.
