Sometimes it turns out that it has been. In such a case, the design must be redone and a large-scale test excavation must be performed, which is very time-consuming and there is a problem that the construction period is delayed. In the case of a buried sign sheet,
If you do not dig into the sheet without actually hitting it with a heavy machine, you cannot know that the pipeline is buried, and you cannot see the information on the sheet. Need to be reviewed. In addition, the fact is that the heavy equipment may reach the pipeline without noticing the buried sign sheet, and the existing piping may be damaged. In addition, although information about the manager's symbol, burial position, and pipeline type can be obtained from the burial mark on the ground, more information such as burial depth, number of pipelines, cable type, laying time, laying contractor, etc. We cannot get detailed information that is urgently needed for maintenance, disaster recovery, etc.
It was necessary to check the documents kept by the administrator. The present invention has been made in view of the above circumstances, and an object of the present invention is to make it possible to easily obtain information about a buried pipeline or a cable, and to provide detailed information such as a maintenance / inspection history and a cable type. Is to be able to be confirmed locally.

る手間を省くことが可能になる。DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a diagram showing the construction of a marking tape according to an embodiment of the present invention. As shown in the figure, RFID tags 2 are attached to a long tape 1 at predetermined intervals.
The tape is preferably made of resin such as polyethylene from the viewpoint of long-term use, but may be made of metal. It should be noted that the shape may not be a tape shape, but may be a string shape. The tag spacing is 0.
A distance of 5 to 5 m is desirable. That is, the communication distance of the RFID tag is currently about 6 m at the maximum, and an interval of 5 m or less is desirable considering that information can be constantly monitored on the route. Also, if the interval is too small, the cost will increase although it is cheap. Therefore, the interval of 0.5 m or more is desirable. RFID tags currently on the market are those in which an IC chip consisting of a memory that stores ID information and a communication circuit and a microminiature antenna are sandwiched and sealed in a resin sheet, resin, silicon, or glass. Some of them are housed in a case, and you can attach them to tape. Further, the resin sheet for sealing may be formed into a long tape shape, and the IC chip and the small antenna may be sealed at a predetermined interval to form a labeling tape. By doing so, it becomes possible to save the trouble of installing the RFID tag later.

る。FIG. 2 shows an example of a method of laying the marking tape. As a laying method, it is possible to adopt a method in which the marking tape 1 is inserted into the buried pipeline 3 as shown in FIG. Usually, a wire is often left in the pipeline, and if this wire is used, the marking tape can be easily inserted even in an existing pipeline, but at the tip of the tape 1. A parachute may be attached and blown into the pipe with high-pressure air, which is a so-called wind-down method. This laying method has the advantage that it can be easily applied to existing pipelines, and even if the marking tape should be replaced, it can be easily replaced. Also, when confirming the buried position of the existing pipeline, it is possible to easily confirm the buried position of the pipeline by inserting the marking tape into the pipeline. further,
Since it is also possible to measure the distance from the RFID tag by measuring the reception intensity of the electromagnetic wave returned from the RFID tag with a reader and analyzing the relationship between the reception intensity and the distance, for example, as shown in FIG. Like this, if you put the tape for marking the buried object in the pipe, you can know the depth of the pipe,
It is possible to know beforehand the depth that can be excavated without damaging the pipeline. If the serial number is written from one side on the RFID tag of this marking tape, the length of the pipe from the manhole can be roughly known from this number.

It is possible to embed the embedded object labeling tape for the number of pipelines, but only one embedded object labeling tape is laid for multiple pipelines and the information of multiple pipelines is stored together in the RFID tag. It is also possible to leave it. As the information to be stored in the RFID tag, for example, not only the name of the manager, the burial position, the type of pipeline and the number of pipelines, the type of cable, the laying time, the laying company, but also the rewriting and addition of information is possible. ,
Information necessary for maintenance and disaster recovery, such as maintenance and inspection history and cable replacement history, can be considered. Also, R

応用できる。As described above, the following effects can be obtained. (1) By using a long sign body attached with a wireless response tag, it becomes possible to accurately obtain information on buried pipelines and cables on site, which eliminates the need for documentary preliminary surveys and test excavation. Since there is no need to change routes afterwards, it will be possible to proceed with the construction accurately. Further, if the elongated sign body is inserted into the existing pipeline, the buried position of the existing pipeline can be easily confirmed, and test excavation or the like becomes unnecessary. Furthermore, by laying the above-mentioned long body for buried object marking between a buried object such as a pipeline and the ground surface, the same function as that of a conventional marking sheet can be provided. (2) When performing maintenance or recovery from a disaster, detailed information such as maintenance and inspection history, cable types, and laying routes can be confirmed on-site, which enables immediate response. Also,
Since information can be stored and transmitted as electronic information, long-distance communication means such as a mobile phone can be attached to the reader, and information can be exchanged with a host computer that performs collective management. It can also be applied to management systems.
