西气东输管道工程西起新疆轮南首站,东至上海,全长约4000km,管道直径为φ1016mm,设计压力为10.0Mpa,是我国“十五”期间五大工程建设项目之一,对西部大开发具有重要意义。工程线路长、施工难度大,尤其是河流穿越,难度尤为突出。管道穿越黄河2次,跨越黄河1次,穿越长江1次,穿越淮河1次。河流穿越为整个线路工程的咽喉工程,是关键控制点。现将西气东输工程河流穿
The West-East Gas Pipeline Project starts from the first station of Lunnan in Xinjiang and reaches the east of Shanghai with a total length of about 4000km. The diameter of the pipeline is φ1016mm and the design pressure is 10.0Mpa. It is one of the five major construction projects in China during the “Tenth Five-year Plan” Great development is of great significance. Long project lines, construction difficult, especially the river through, the difficulty is particularly prominent. The pipeline crossed the Yellow River two times, crossing the Yellow River once, crossing the Yangtze River once, crossing the Huaihe River once. River flow through the throat of the entire line project, is the key control point. Now the West-East Gas Pipeline project to wear
