The magnetic sensor 22 transmits a high-frequency magnetic field underground 8 through a transceiver 24 that transmits and receives a high-frequency magnetic field, and receives a magnetic field 27f induced in the buried pipe 25 and 26, which is transmitted to the transceiver 24. The approximate horizontal position of the buried pipes 25 and 26 is output to the output device 28 based on the signal. On the other hand, the radar antenna 23 transmits electricity underground 8 through a transmitter/receiver 29 that transmits and receives radio waves.The transmitter/receiver 29 detects this, and based on the signal, the image output device 31 sends detailed locations of the buried pipes 25 and 26. , and output and display the depth, size, etc. The output display of the magnetic sensor 22 and radar antenna 23 is switched by a switch 3.

The automatic traveling device 20 equipped with the magnetic sensor 22 is operated by the operation device 21 and moved near the expected buried position of the buried pipe 25, 26, where the magnetic sensor 22 is switched on by the switch 32.
The transceiver 24 and the output device 28 output signals to detect the approximate horizontal position of the buried pipes 25 and 26. After that, the switch 32 switches to the mode of the radar antenna 23, and the radar antenna 23,
and detecting the buried pipes 25 and 26 using the transceiver 29,
The detailed position, depth, size, etc. of the buried pipes 25 and 26 are output and displayed on the image output device 31.

Since the device receives the magnetic field induced by the magnetic field 6, there is no possibility of incorrect determination. Furthermore, a radar antenna 23
Even if a disturbance signal mixes with the buried pipe 25, 26, it is determined in advance that there is a buried pipe 25, 26, so it is easy to find the pipe, and the radar antenna 23
Since this system receives and detects the reflected waves reflected by the buried pipes 25 and 26, even if multiple buried pipes are located adjacent to each other, the position of each individual buried pipe can be easily detected. .

For example, even if all combinations are used, such as a magnetic method and a sonic method, or a single radar method and a sonic method,
The detection can be done similarly. Needless to say, when the sonic method is adopted, the cost of the transmitter/receiver and output device that is suitable for the sonic method is biased. Further, if the magnetic method, the radar method, and the sonic method are added, and the sonic method is used as a backup for the radar method, the detection will be further improved.
