摘要
着重介绍了近年来国内外在定向钻、顶管等非开挖穿越中新设备和新技术工艺的发展以及应用,尤其是在大口径、超长距离、不良地质条件下的非开挖技术工艺和应用,为国内穿越工程进一步拓宽、优化设计方案和设计思路提供借鉴。
Described are development and application of new directional drilling equipment and techniques to non-excavation crossing at home and abroad in recent years.Especially described are new non-excavation crossing techniques and application of the techniques to long-distance and large diameter pipeline crossing in poor geological conditions,which is beneficial to optimize design options in domestic crossing projects.
