摘要
对于充满泥浆的大口径钻孔轴线是否达到设计要求,需要对钻孔轴线的垂直度进行检验。然而常用的铅锤目测法与轴心系线法都无法准确检验钻孔轴线是否偏移。在统一采用桶体检验的基础上,对传统的方法进行改进。采用钢管隔离,人造空间,运用光走直线、垂直对焦的原理,制作了同步变形桶体、管内发光、镜显交点、以测量仪器为钻孔轴线中心点的"光源十字镜检测器具"。经实测检验,证明该检验器具满足设计要求,从而解决了对充满泥浆的大口径钻孔轴线是否偏移的检测问题。
For heavy-caliber drilling axis of mud filled whether to achieve the design requirements, which needs to carry on the examination of the drill hole axis＇s verticality. However, the commonly used plumb bob ocular estimate estimation by eyes and the axis-line are the long-base method, which can not examine the drilling axis accurately whether to displace. Based on the barrel body test in the uniform application, makes the improvement to the traditional method. Use of the steel pipe isolation, the man-made space, and using principle that light to go straight, the vertical focusing which manufactured ＂photo source stauroscope examination appliance＂ that the synchronized distortion barrel body, in the tube shines, the mirror obviously point of intersection, metering equipment as drill hole spool thread central point. The experimental tests prove that the examination appliance satisfies the design requirements, thus examination question that the heavy-caliber drill hole filled with mud spool thread whether to displace is solved.
