山区长输管道造价编制要点

Cost Compiling Key Points of Long-distance Pipeline Crossing Mountainous Areas

山区管道建设在长输管道项目中占有较大的比重,山区地形地貌复杂,多种因素造成山区管道的工程量较难把握,其投资也高于一般平原地区,编制较为合理的工程概预算对于保障项目正常进展、控制项目投资有着重要的意义。文章结合山区地理特点及山区施工经验,介绍了施工便道、施工作业带、土石方、运布管、管道组焊、管道检测、水工保护等分项工程的造价编制要点。

Pipeline construction in mountainous areas takes a great ratio of long-distance pipeline pro- jects. Due to topographic complexity in mountainous area, the engineering quantity of mountainous pipeline construction is not easy to control, and its investment is higher than that in plain area. Compiling reasonable engineering budget can not only ensure the project to run well, but also control the investment effectively. Based on the geographic features and pipeline construction experience in mountainous area, the article intro- duces the cost compiling key points of pipeline subprojects such as construction service road, working zone, earthwork, pipe transport and layout, pipe welding, pipeline inspection and hydraulic protection.
