摘要
近年来,国内管道的河流穿越技术得到了快速发展,而穿越方式的合理选择是管道敷设设计中的难点问题,也是工程设计的重要关注点。文中通过对各种河流穿越技术进行对比分析,总结不同穿越方法的优缺点,适用范围、适用条件及其可能产生的环境影响,结合工程实例介绍具体穿越方案的选择,为长输管道河流穿越方案的合理选择提供借鉴。
In recent years,the pipeline crossing-river technology has developed rapidly,but the rational selection of pipeline crossing-river is not only a difficult problem in the design of the pipeline,but also an important concern in engineering design.This paper reviews and summarizes different construction methods of long-distance transport pipelines crossing rivers and compares the advantages and disadvantages of the technologies between buried trenches,directional drilling,tunneling,etc. It also gives an introduction to the proper application and the required condition of each specific method and analyzes the effect of different methods on the environment. Finally,an engineering example is introduced here to elaborate the selection of specific crossing schemes. It can be served as a good reference for a reasonable selection of long-distance pipeline crossing rivers.
