摘要
介绍了宁波-上海-南京进口原油管道定向穿越长江施工的设备配置以及管道水平钻进的入土角、出土角、曲率半径和穿越深度等设计要素的确定方法,分析了管道强度和回拖力的计算方法,详细阐述了施工过程。
It introduce the equipment of the petroleum pipeline from Ningbo by way of Shanghai to Nanjing from under the bottom of the Yangtze River with the pipeline plane directional drill as well as how to confirm the degree of ingress soil and the degree of export soil and the radius of curvature and the depth under the bottom of the Yangtze River. The methods for ensuring the pipeline intensity and the pulling power are analyzed and then the course of construction is expained.
