摘要
针对某供热管道水平定向钻穿越河流工程,确定钢管壁厚,设计穿越轨迹,进行钻机选型。对管道回拖工况下的应力和径向屈曲失稳进行校核,提出施工注意事项。
Aimed at a heat-supply pipeline river crossing project using horizontal directional drilling technology, the steel pipe wall thickness is determined, the crossing track is designed, and the drilling machine is selected. The stress and radial buckling instability of pipeline under pull-back conditions are checked, and the precautions in the construction are proposed.
