<p>PURPOSE:To easily execute a deciding work in a short time by allowing a current to flow to a buried object, and measuring a magnetic field generated from said buried object on the ground, as a plane distribution. CONSTITUTION:By allowing the current to flow to the buried object 1, the magnetic field generated from this buried object 1 is measured on the ground 2, as the plane distribution. From its distribution, the buried position and depth are calculated, and also, from the intensity of the magnetic field, the current conducted to the buried object 1 is calculated. That is to say, an enclosure 5 into which there pieces or more of magnet sensors 3 are integrated is brought to sweeping manually along the buried object 1 by a sweeping handle 5a. Also, a sweep distance is detected by a sweep encoder 4 attached to a tire part for supporting the enclosure 5. In such a way, the place of deterioration and the size of deterioration of the buried object 1 are decided, therefore, the deciding work can be easily executed in the short time.</p> |
