河南省南水北调供水配套工程在管道管材选择设计中PCCP管材占整个管材比重的80%以上，配套工程输水管道的设计质量直接关系到工程的安全性和经济性。由于PCCP管与其它管材相比具有其特殊性，在地形复杂、线路长的输水管线中，弯管、阀件、封头等配件数量较多，这些配件处必须采取止推措施设计，止推设计是输水线路安全运行的重要设计部分，止推设计的合理性对输水管线的正常运行、工程施工进度、工程造价等都具有很大的影响。本文结合河南省南水北调供水配套工程实际情况，介绍了几种常用的止推方式，以供设计人员在工程设计时参考运用。

PCCP pipe accounts than 80% of the whole pipe in the pipe steel tubes selection design of the South-to-North water diversion project in Henan province, the design quality of water pipe supporting engineering is directly related to the safety and economy of the engineering. Compared with other pipes, PCCP tube has its particularity, the parts number of pipe, valve parts, sealing are more in the water pipeline with complex terrain and long line. Thrust design measures must be taken in these parts, thrust design is an important design part of the safe operation of water circuit. The rationality of thrust design has great influence for the normal operation of water pipeline, the engineering construction schedule, the construction cost and so on. In combination with the practical situation of the water supply project of South-to-North water diversion in Henan province, this paper introduces several kinds of commonly used ways of thrust as the reference for designers to use in engineering design.
