Description

Location information acquisition method of underground pipeline {method for conduit line informing location}

The present invention relates to a method for acquiring position information of underground pipelines, and more particularly, to install magnetic materials at upper portions of underground pipelines which are buried in the ground to allow fluid, gas, steam, etc. to be moved, and are generated from the magnetic bodies. By checking the magnetic field of electric current on the ground with a magnetic detector and checking the embedding position and the direction of the underground pipeline, it is applicable to underground pipelines made of non-ferrous metals and metals, and it is easy to install magnetic materials and improve measurement efficiency. It relates to a method of obtaining location information.

As urbanization progresses rapidly, the installation of water and sewage pipes, city gas supply pipes, oil transfer pipes, electric and communication lines, etc. is increasing rapidly to expand infrastructures such as electricity, telecommunications, and water and sewage. These facilities are mostly buried underground (underground) due to their beauty and protection.

However, since information on the location or depth of such underground facilities is not accumulated, it is difficult to visually grasp the location or state of the underground facilities, which makes it difficult to maintain the underground facilities. In addition, when installing new underground works or construction of buildings, time and costs are increased in order to accurately locate the existing underground facilities, and also destroys existing underground works during construction, or the safety of workers. In other words, since there are numerous pipes in the area where social infrastructure is concentrated, accidents may occur if the location and condition of the pipes are not known. In contrast, although a guide plate through which a communication cable line or a gas supply pipe passes is displayed on a road, etc., there is a problem in that accurate information about the position and depth of the road is dependent on the existing design.

Conventionally, in order to measure underground buried material on the ground, a method of propagating electromagnetic waves, ultrasonic waves, or ultra-high frequency waves to the ground, and then measuring a change in wavelength propagated through the medium and buried material has been used.

However, the electromagnetic induction method according to the related art is classified into a direct method and an indirect method. The indirect method is used to induce an electric current that affects a tube other than the tube to be explored by an alternating magnetic field transmitted from a transmitter when the buried material is complicated. Therefore, there is a problem that the accuracy of the position measurement is low. In addition, the direct induction method is a method of grounding one terminal on the ground about 5-7 m in a direction perpendicular to the underground buried material, there is a problem that the accuracy is high but the working conditions are difficult.

In addition, since the electromagnetic induction method according to the prior art basically can measure only the conductor, there is a problem that a special sensor device is required for the exploration of the non-metallic pipe.

In addition, in the conventional underground radar irradiation method, since the underground medium is physically heterogeneous than the air, which is the propagation path in the radar, the shape and position of the reflector are very complicated, and the signals reflected from the underground have a lot of noise. In addition, since the electrical conductivity of the topsoil layer through which the electromagnetic wave passes is relatively high, attenuation of the electromagnetic waves occurs in the topsoil layer, and thus, it is impossible to detect the depth below the surface, and about 30m is known as the limit depth.

In addition, the acoustic wave channel measurement used in the conventional sound wave irradiation method is a probe for water pipes, and if the sound wave is inserted into the pipe by connecting a vibrator regardless of the metal or nonmetal material, the position can be measured. There is a problem that is impossible.

The present invention has been made to solve the above problems, an object of the present invention is to generate a magnetic material by installing a magnetic material at a certain interval in the upper part of the underground pipeline to be buried in the ground to move fluid, gas, steam, etc. Understand the magnetic field of the current to be detected by the magnetic detector on the ground and then check the embedding position and the direction of the underground pipe, it is applicable to all underground pipelines made of non-ferrous metals and metal materials, easy to install magnetic material and improve the measurement efficiency The purpose of the present invention is to provide a method for obtaining location information.

Magnetic material detection step (S2) and location information acquisition step (S3) is made.

The magnetic material attaching step (S1) is a magnetic material attached to the upper portion of the underground pipe to be buried in the ground, the magnetic body 100 is to be installed at least one or more along the longitudinal direction on the upper portion of the underground pipe (200).

At this time, the magnetic material 100 is preferably formed to be curved, the bottom surface to be disposed on the upper portion of the underground pipe line 200 made of a circular pipe structure, the bottom surface is bonded or fused to be fixed to the underground pipe line 200 It is preferable to fix it.

The underground pipeline 200 in which the magnetic material 100 is fixed as described above is buried to perform a function of the underground pipeline 200 for moving fluids, gases, and steam, and the like. It is possible to check the position through the magnetic material detection step (S2) for city maintenance.

 Magnetic material detection step (S2) is to detect the magnetic material 100 attached to the underground pipeline 200 with the magnetic detector 300 in the ground to determine the position of the underground pipeline 200, such a magnetic material detection step S2 detects the first sensing step (S2-1) for detecting the magnetic material attached to the underground pipeline and the other magnetic material located in the vicinity of the magnetic material 100 detected through the initial sensing step (S2-1) Line detection step (S2) for detecting the magnetic material detected through the peripheral detection step (S2-2), the initial detection step (S2-1) and the peripheral detection step (S2-2) along the line of the line in which the magnetic material is located -3)

That is, as in the initial detection step (S2-1) by detecting the magnetic field generated from the magnetic material 100 with the magnetic detector 300 on the ground to grasp the position of any one of the magnetic body attached to the underground pipeline 200 The position of the conduit 200 is confirmed, and then the surroundings are radially detected based on the detected magnetic material 100 as in the peripheral sensing step S2-2 so as to confirm the embedding direction of the underground pipeline 200. Another magnetic material disposed in a position close to the detected magnetic material 100 is detected, and then a connection line connecting the point detected in the initial detection step S2-1 and the point detected in the peripheral detection step S2-2. By detecting the magnetic material installed while moving along the extension line extending in both directions in the above, it is possible to check the embedding position and the embedding direction of the underground pipeline 200 as in the on-line detection step (S2-3).

The magnetic body detector 300 detects the magnetic field of the magnetic body, and is configured to have a detection unit having a bar structure or a disc structure, and since it is already widely known and used in the art, a detailed description thereof will be omitted.

In the location information acquisition step S3, after confirming the location information of the magnetic bodies 100 through the line detection step S2-3, the location information acquisition step S3 obtains the location information of the underground pipeline 200.

That is, it is possible to visually identify the location information of the underground pipeline 200 by drawing a line of the points detected on the ground to perform maintenance and the like, otherwise the mobile terminal of the magnetic detector 300 It is also possible to receive the detection signal to display the location received on the map.

It is desirable to repeatedly mark the detected points while moving along the lines and connect them with lines.

Here, in the magnetic material attaching step (S1), at least one magnetic body 100 is installed in the upper portion of the underground pipe line 200 along a length direction to form a magnetic part 400, and the magnetic part 400 is The underground pipe line 200 is further installed while maintaining a constant interval along the longitudinal direction.

That is, by adjusting the number of the magnetic body 100 that is attached to the underground pipe line 200 and forming the magnetic part, it is possible to distinguish the underground pipe lines 200 which are embedded and the magnetic body is installed.

Preferably, the interval between the magnetic body 100 included in the magnetic part 400 is preferably maintained at 1m, the angle of the magnetic portion is preferably maintained at 3m.

In other words, if the distance between the magnetic body 100 is maintained within 1m, it is difficult to determine the number of the magnetic body by overlapping the magnetic field, if the length is more than 1m, the measurement length of the magnetic material is delayed and the detection time is delayed. In addition, when the interval between the magnetic parts 400 is maintained within 3 m, the measurement time and detection time of the magnetic part 400 are delayed when overlapping with the magnetic field generated in another magnetic part and when the distance is 3 m or more.

Here, the magnetic body 100 is formed in a block structure to be bonded or fused to the underground pipe line 200, otherwise the magnetic body 100 is formed in a powder form to apply an adhesive on the upper portion of the underground pipe line 200 It is also possible to attach it afterwards, and it is preferable to maintain the distance between the magnetic material and the magnetic part at the position where the magnet in powder form is sprayed.
