Generally, the sewer line includes an auxiliary facility formed in pipelines and pipelines for transferring sewage to a public sewage treatment facility, a simplified public sewage treatment facility, a sewage storage facility, or to discharge the sewage to rivers, seas, and other shared water surfaces.

The sewage line includes an excellent pipeline through which rainwater flows in and out, and a sewage line through which sewage flows in and out.

The accessory facilities formed in the sewer pipe line are formed in the upper direction with respect to the sewage pipe, and include connection pipes (or connection pipes) for the work of the operator, manholes covering the connection pipes, water receptacles, connection pipes and the like.

Recently, sewer pipes have been databaseed with the viewpoints, end points, directions, and junctions, and the locations of the sewage pipe accessory facilities are also database (DB). However, old sewage pipes and related facilities buried long ago are not databaseed It is frequent.

Old age sewer lines and affiliated facilities which are not database are often not consistent with the diagrams showing the change of the surrounding terrain with the passage of time, the viewpoint of the sewer line, the end point, the direction, the branch point, and the location of the accessory facilities of the sewer line.

Particularly, the connection pipe or the manhole, which is an attached facility installed in the old sewer pipe, is often covered with a part of the soil or covered by the shrubbery when it is not managed by the passage of time.

Korean Patent No. 10-1501160 discloses a sewer pipe facility investigation device and method (registered on Mar. 4, 2015), which discloses a technique for converting the position of a manhole into a database on the ground using a smartphone or the like .

However, in the above apparatus and method for surveying the sewage line facilities, when the old sewer line and old sewage line are covered with soil or shrubs and can not accurately recognize the actual location of the sewer line, the location of the sewer line and the manhole It has technological constraints that can not be grasped.

Recently, non-destructive exploration method using ground penetrating radar (GPR) to investigate underground strata, underground burrows, caves and cavities can be used to explore cavities around sewage pipes and sewage pipes.

Surveys using surface transmission radar emit electromagnetic waves from a transmitting antenna, and then reflect or transmit the target in the ground to image the ground structure and underground objects using electromagnetic waves sensed by the receiving antenna, and use this data to search the sewer pipe .

However, in the case of using the surface transmission radar, the surface transmission radar is very bulky and expensive. Especially, when the old sewer pipe and old facilities are covered with soil or forest, or the terrain is not flat, It is also difficult to exploit the old sewer pipe and old facilities.
