Guide positioning method and positioning instrument for horizontal directional drilling

The invention discloses a horizontal directional drilling guiding position method and position indicator, which comprises the following parts: sensing emission probe in the guiding drilling tool, walking type position follower and driller monitor on the drill, wherein the sensing emission probe is composed of angle sensor, signal disposing and transmitting unit, solenoid coil and battery, which sends the measured the incidence, facing angle, temperature and other parameters to the follower through wireless electromagnetic wave; the position follower calls the parameter of underground probe to measure position and depth according to the signal relative strength distribution, whose final result is sent to the driller display through wireless pattern. The invention is convenient to operate for the driller personnel.
