The drilling machine clamps a drill rod at each time, the clamped drill rod is in threaded connection with the previous drill rod through the rotating power of the drilling machine, then the drilling machine drives the whole drill rod to be horizontally pushed inwards, and water flow cooling is accompanied when the drill rod is pushed. The depth of the drill rods which are connected end to end and driven into the ground surface is determined by the number of the drill rods, and the number of the drill rods multiplied by the length of the drill rods is the depth of the driven ground surface.

However, when the geological drilling machine continuously drills or continuously retreats, the technology cannot accurately identify the periodic jump, and the hidden trouble of data counterfeiting caused by artificially simulating the periodic drilling process exists. In order to solve the problem, the characteristics of a geological drilling rig drill rod need to be combined, an image processing technology needs to be optimized, and the accuracy of depth measurement needs to be improved.
