- 山区地段敷设油气输送管道时,由于沿线地形起伏较大、表面岩石不规则出露、遍布陡坡长坡、河谷纵横、道路崎岖,不像平原施工易于修出大型机械能施展开的施工便道和施工作业带,给管道安装、尤其大口径管道安装带来巨大困难。文章针对不同的山体特点及地形地貌,分析了山区段管道施工通道修筑及管沟开挖技术,主要包括在横坡、纵坡及其他特殊地段修筑施工通道技术和在横坡、纵坡上开挖管沟技术。这些技术在川气东送管道山区段线路施工中成功应用,保证了川气东送管道工程的顺利完工,可为今后同类山区段长输管道工程施工借鉴。
Because of undulating terrain,irregular exposed surface rocks,spread steep slopes and long slopes,crisscross valleys and rugged roads along pipeline routes in mountainous areas,the pipeline laying in mountainous areas,unlike in plain,is hard to build construction access road and operating zone for large machinery running,and brings great difficulties to pipeline installation,especially to large diameter pipeline installation.This article analyses the technology of building construction access roads and excavating trenches in pipeline construction in mountainous areas according to different characteristics of mountains and terrains,including the technology of building access roads in cross slope,longitudinal slope and other special sections，and the technology of excavating trenches in cross slope and longitudinal slope.These technologies were successfully applied in the mountainous pipeline construction of Sichuan to East Gas Transmission Pipeline and ensure that the Sichuan to East Gas Pipeline Project completed successfully.It can provide reference for future similar long-distance pipeline construction projects in mountainous areas.2012,05(05): 86-88 收稿日期：2011-8-31分类号：TE973.6作者简介：宋龙进（1982-），男，江苏如皋人，工程师，2004年毕业于中国石油大学（华东） 过程装备与控制工程专业，现从事管道抢维修和技术质量管理工作。
