水平定向钻拖管法工程实践

Practice of horizontal directional drilling method

结合具体工程实例,介绍了采用水平定向钻拖管法铺设过路污水管工程的施工情况,重点介绍了定向钻孔轨迹设计,详细阐述了定向钻进施工工艺,指出水平定向钻拖管法在穿越道路排水管施工中具有一定的优势,比明挖技术节约工期、降低造价。

Combined with a project, it introduces the construction situation of a project applying horizontal directional drilling method to pave sewer across road, particularly introduces directional drilling track design, elaborates its construction technique, and points out that horizontal directional drilling method is advantageous in sewer across road construction, and it is shorter in construction period and cheaper in cost compared with open-cut excavation technology.
