摘　　要：目前,豫东地区饮用水源主要是地下水,盐碱严重、水质较差,长期饮用会对人体健康造成严重影响。加快实施引江济淮工程(河南段)为人民群众提供安全可靠的水质保障。文章结合引江济淮工程(河南段)供水工程吊装大口径PCCP管材的经验,从四个方面分别介绍了引江济淮工程PCCP管道吊装施工技术、施工过程质量控制、安全保护措施及文明施工、环境保护,总结了大口径PCCP管道吊装施工过程中的技术要点,为其他类似大型水利工程PCCP管道的安装提供了一定的参考价值。At present,the drinking water source in eastern Henan is mainly groundwater,with serious salt-alkali level and poor water quality.Long-term drinking will have a serious impact on human health.We will accelerate the implementation of the project of diverting water from the Yangtze River to the Huaihe River(Henan section)to provide safe and reliable water quality guarantee for the people.Combined with the experience of hoisting large-diameter PCCP pipes in the water supply project of the water diversion project from the Yangtze River to the Huaihe River(Henan Section),this paper introduces the hoisting construction technology,quality control in the construction process,safety protection measures,civilized construction and environmental protection of PCCP pipes in the water diversion project from the Yangtze River to the Huaihe River from four aspects,and summarizes the technical points in the hoisting construction process of large-diameter PCCP pipes,It provides a certain reference value for the installation of PCCP pipes in other similar large-scale water conservancy projects.
