For example, using an exploration device (Strike Scan, GSSI, USA) equipped with an exploration function by the electromagnetic wave radar method, while moving the exploration device on the surface of a concrete structure, on the exploration line orthogonal to the movement direction of the device, By exploring electromagnetic waves from the device toward the concrete structure, exploration is carried out to determine whether there are any buried objects on the exploration line.

  In such exploration work, when there is an embedded object on the exploration line, the radiated electromagnetic wave is reflected by the surface of the embedded object and received by the receiver, and from the time from transmission to reception of this electromagnetic wave, The position of the buried object in the depth direction is specified, and the position of the specified buried object in the depth direction is displayed on the monitor as a waveform. In addition, by measuring the movement distance of the device from the starting point to the survey line by operating a distance meter following the rotation of the wheel, the horizontal position of the buried object is monitored with a waveform based on the measured distance Is displayed.

  Also, in the exploration work as described above, if there are objects on the exploration line, the exploration line is illuminated by the laser light emitted from the device, so the area illuminated by the laser light is marked. By marking using various markers such as markers, the mark can be written at the position where the embedded object exists.

  By the way, when one worker performs the above-described work, the worker fixes the exploration device on the surface of the concrete structure with one hand and is illuminated with laser light with the other hand. Since it is necessary to mark with various markers on the survey line, it is necessary to be skilled in those operations, and inexperienced workers can accurately mark the survey line on which the buried object exists. Can not.

  In addition, when two workers perform the above work, one worker fixes the exploration device on the surface of the concrete structure, and another worker uses a marker to illuminate with laser light. It will mark the survey lines that have been made, and it will take a lot of work to do so.

  In order to cope with the above problems, it is conceivable to use an exploration device as described in Patent Document 1. The exploration device described in Patent Document 1 includes a marking device that ejects ink, and by ejecting ink from the marking device onto the exploration line of a concrete structure in which an embedded object is present, It is configured to mark the mark with ink.

  By using the exploration device described in Patent Document 1, the marking device can automatically mark the exploration line on which the buried object exists, so that the experience level is not affected by the skill level of the operator. Even a shallow worker can accurately mark the mark on the survey line where the buried object exists. Moreover, a mark can be easily described on an exploration line where an embedded object is present by one worker without requiring a plurality of workers.

  However, since the exploration device described in Patent Document 1 requires a marking device that ejects ink onto the surface of a concrete structure, the structure of the exploration device as a whole is complicated. In addition, the entire apparatus is increased in size by adding the marking apparatus.
