The pipeline that laid along the companion trip road, tunnel and ridge of mountain area, submits wave to rise and fall, drop is greater, difficulty has increased for pressure examination and blow to sweep. Taking Lanchengyu 8th mark section of petroleum pipeline for example, construction experience of mountain area has been introduced such as partition of section of pressure examination and blow to sweep, location option of water up and down as well as major technical measures.2002,4(4): 27-29 收稿日期：2002-3-15分类号：TE4作者简介：尹辉庆,工程师.1992年毕业于承德石油高专焊接工艺及设备专业,先后在首钢3＃高炉改造、大连20万m3浮顶油罐、垂杨-吉林输油管道、香港新机场燃油管道、陕京天然气管道、义马-郑州煤气管道和兰成渝成品油管道等工程中担任基层处和项目技术负责人.目前在中石油管道三公司工程技术部从事施工管理工作.通讯地址:河南省中牟县,邮编:451450,电话:0371-2152330(办)
