摘　　要：廉江核电项目九洲江引水工程共有7处过河段,河道地质条件复杂,在水平定向钻穿越施工过程中通过对管道防腐层及防护层设计、扩孔、修孔、清孔、回拖等各个施工工序的优化,经2次试回拖,验证了设计、施工优化的效果,后续管道穿越施工非常成功。Lianjiang Jiuzhou River water diversion project nuclear power project a total of seven river,river geological conditions,through the horizontal directional drilling through the pipeline corrosion layer,protective layer design,expansion,hole,hole,back to the optimization of the construction process,after the second test back to drag,verified the design,construction optimization effect,subsequent pipeline through the construction is very successful.
