摘要
通过对冶河灌区二干渠倒虹吸管道施工中的碎石垫层、三七灰土、管道安装等施工方法和关键环节取得的成功经验进行总结，分析了影响管道施工质量的关键因素，提出水利工程大直径混凝土预置管道施工的注意事项、改进措施，有效防止了管道施工中基础沉降、漏水、管道断裂等多发问题，对类似管道工程施工具有重要的借鉴意义。
It summarized the experiences of pipeline construction technology about gravel cushion, 3 ： 7 lime-soil, pipeline installation in the 2nd main canal of Yehe irrigation district, and analyzed the key factors influenced the construction quality. It proposed the cautions and improvement measures in the prefabricated concrete pipeline construction with big diameter in hydraulic engineering, which can prevent the foundation subsidence, leakage and broken effectively.
