    摘要:

    在工程勘察中采用水平定向钻探技术,可以高效地解决一些垂直钻孔无法解决的问题。论文概述了水平定向钻探技术在非开挖铺设管线、油气钻井、地质勘探等领域的技术现状,认为在工程勘察领域的应用前景广阔。分析了应用水平定向钻探进行工程勘察在适用能力、勘察速度、勘察精度等方面具有的优势,提出水平定向钻探适用于深埋隧道等水平线状工程、既有建筑加固工程、考古发掘探测等领域的勘察。最后对应用于工程勘察的水平定向钻探技术需要研发的重点方向提出了建议,包括超长孔钻进技术、轨迹控制技术、连续取心技术、综合测试技术等。

    Abstract:

    The horizontal directional drilling technology for engineering investigation can solve some problems that the vertical drilling fails to solve. This paper introduces the status of the horizontal directional drilling technology in trenchless pipeline laying, oil and gas drilling, geological exploration, and the application in engineering investigation. The advantages of the horizontal directional drilling in engineering investigation in terms of applicability, survey speed and survey accuracy is discussed, we conclude that the horizontal directional drilling is suitable for investigation in the fields of deep buried tunnels and other horizontal linear projects, existing building reinforcement projects, archaeological excavation and exploration. Finally, this paper puts forward suggestions for the development of the horizontal directional drilling technology applied to investigation, including super-long hole drilling, trajectory control, continuous coring, and comprehensive measurement.
