输油管道工程特征及其水土流失防治措施--以平原区和丘陵区为例

摘要

为了在输油管道建设过程中采取合理的水土流失防治措施，减少水土流失，对输油管道工程的项目组成、施工组织进行了分析，重点介绍了一般管道敷设和穿越公路、铁路、河流段管道敷设施工工艺。在平原区和丘陵区作为一级分区的基础上，将输油管道工程分为管道作业带区、穿越工程区、站场阀室区、施工便道区和施工生产区5个防治分区。对分段管道的防治目标值加权平均得到工程的水土流失防治目标值，在此基础上分别确立了平原区和丘陵区输油管道工程的水土流失防治措施体系，分析工程措施、植物措施和临时措施的特点，因地制宜地采取合理措施来减少输油管道工程建设过程中的水土流失。研究成果为输油管道工程的水土流失防治措施提供了参考依据。%The aim of this research is to reduce soil and water loss by taking appropriate countermeasures during the construction of oil pipeline projects.The composition,construction organization and techniques of oil pipeline con-struction are analyzed.The techniques of laying ordinary pipeline and pipelines crossing highway,railway,river are introduced in emphasis.Moreover,pipelines in plain area and hilly area are partitioned and are further divided into 5 sub-zones (pipe laying zone,crossing zone,station and valve chamber zone,construction road zone,and construction zone).The objectives of soil and water loss are determined by the weighting of objectives of each seg-ment.On this basis,systems of different countermeasures for hilly area and plain area are established,and the fea-tures of engineering measures,plant measures,as well as temporary measures are analyzed.Appropriate measures are adjusted according to specific local conditions.This research is a reference for the control of soil and water loss for oil pipeline project.
