探棒腔

    探棒安装在钻头的探棒仓内，探棒随钻头一同在地下移动，探棒实时测量钻头的空间位置、运行状态等信息并将该类信息以电磁信号的方式发送给地面上的接收装置。地面上的操作人员根据地下探棒测量的钻头空间位置可以判断出钻头实际运动轨迹与设计轨迹的偏差，从而调整钻头的运动方向，以保证钻头按设计路线前进。

    The probe rod is installed in the probe rod bin of the drill bit. The probe rod moves underground with the drill bit. The probe rod measures the spatial position and operating status of the drill bit in real time and sends the information to the receiving device on the ground by means of electromagnetic signals. The operator on the ground can determine the deviation between the actual movement trajectory and the designed trajectory based on the drill space position measured by the probing rod, so as to adjust the movement direction of the drill to ensure that the drill moves forward according to the designed route.
