PCCP是一种新型的钢性管材,广泛应用于长距离输水线路、压力倒虹吸、城市供水工程、产业有压输水管线、电厂循环水工程,下水管道、压力排污干管等。与普通管材相比,PCCP管材具有适用范围广,经济寿命长、抗震性能好、安装方便、运行用度低,基本不漏水等优点,在我省南水北调配套供水管道工程中广泛应用。文章以河南省南水北调受水区许昌供水配套工程16号分水口门供水工程建安施工第3标段为例,对PCCP管道施工工艺进行探讨,希冀为南水北调或其他类似工程有所裨益。
PCCP is a new type of steel pipe, which is widely used in long-distance water transmission lines, pressure inverted siphon, urban water supply projects, pressurized water transmission lines in industries, circulating water projects in power plants, sewer pipes and pressure drainage pipes. Compared with common pipe, PCCP pipe has many advantages, such as wide range of application, long economic life span, good seismic performance, easy installation, low running cost and no water leakage. It is widely used in the water supply pipeline project of South-to-North Water Diversion Project in our province. Taking the No.3 Bidding Section of Jianshui Construction of No. 4 Water Supply Project of Xuchang Water Supply Component Project of Xuanshui Water Supply Project in South-North Water Diversion Project of Henan Province as an example, this paper discusses the construction technology of PCCP pipeline and hopes to benefit the South-to-North Water Diversion Project or other similar projects.
