<p>A buried structure detection device characterized by comprising a capacitance sensor attached to a base plate opposed to the ground for detecting a change in the underground capacitance, a reference value memory means for storing a reference capacitance in advance according to changes in capacitance with no target buried object in the ground, a calculating means for comparing the detected change in capacitance with the stored capacitance to detect the presence of a target buried object in the ground, and a buzzer for receiving a signal from the calculating means and giving notice of the presence of the target buried object.</p> |
