仪长原油管道陆水河穿越设计及施工

Design & Construction for Crossing Way of Lu Shui River of YI Zheng-chang Ling Crude Oil Pipeline Engineering

长输管道的大型河流穿跨越方案的确定受河流的地质条件、水文条件、地层情况、穿越环境、河流防洪等因素的影响,本文根据陆水河的水文地质特点、穿越长度、穿越环境等,对悬索跨越、定向钻、大开挖(漂管)穿越等穿跨越方式的设计和施工方案进行了比较分析,确定采用漂管方式进行大开挖穿越方案。本文对其他河流穿越具有较高的借鉴意义。

The way of selection of large river crossing for transportation pipeline is affected by geology, waters, stratum, environment, preventing flood, and other factors. This paper analyzes the ways about suspension cable type, directional drilling, digging according its character, finally we select the way of digging crossing engineering. This article can be used for reference in the same engineering.
