摘要

The space trajectory of laying flexible pipes should not only depend on the processrnparameters in HDD technology. This detection method is introduced to tracernthree-dimensional space trajectory of non-metallic flexible pipes. Based on thisrnmethod, a trajectory measuring instrument is invented by using high-precisionrnHoneywell digital compass to measure the pitch and azimuth angles, and then to setrnup a mathematical model with the minimum radius of curvature method. The actualrnspace trajactory of pipes can be reconstructed accurately, and the three-dimensionalrntrajactory can be visualized when the device is connected to computer terminals. Therninstrument is proved reliable in the worksite.
