On the other hand, after a considerable period of time after laying such cables or pipes underground, a considerable level of displacement may occur in underground buried pipes due to ground subsidence or fluctuation.

It is desirable to grasp the position information on the underground buried pipe, that is, the longitude and latitude coordinates, the depth from the ground surface, the condition of the pipeline, and the like to prevent the above problems. For example, in the case of installing new underground burial, the diameter of the pipeline laid underground can be grasped before laying, and when the pipeline is laid after the excavation work is completed, the latitude and longitude coordinates obtained by GPS are obtained and the depth from the ground surface is measured. This database can be managed by GIS (Geographic Information System).

To this end, there is an urgent need for a method and apparatus capable of accurately determining the location of underground buried pipes without excavation work.

Fig. 10 shows the underground pipeline structure incorporating the position detecting means according to the prior art.

In the figure, first, sand is laid flat on the bottom of the excavation site in order to bury the power lines in the ground, and the underground buried pipes are arranged in parallel at approximately regular intervals on the sand.

Then, the underground buried pipe spacer 10 is inserted into the underground buried pipe at predetermined intervals to mount the underground buried pipe spacer 10 to the underground buried pipe. Next, the magnetic marker 20 is attached to the upper surface of the corrugated pipe where the underground buried pipe spacer 10 is not installed.

However, such a prior art has a problem that the position can be determined only by attaching a specific magnetic marker when installing the underground buried pipe.

Underground buried pipe measuring sensor cable 100 having a connecting slot shown in the buried position and / or the underground buried pipe 1 is buried first in the basement in order to lay the power and / or signal cable or piping in the basement This is to check whether or not abnormality.

The underground buried pipe (1) is made of a structure having a fluidity and resistance to external impacts for embedding such as corrugated pipe, first embedded in the basement, and the desired cable or pipe is disposed therein.

The sensor cable 100 for underground buried pipe measurement, in the underground buried pipe just installed, or the underground buried pipe in the state that the cable / pipe inside of the state is removed for repair, in a state along the interior space temporarily, It supports the sensing of values indicating the location and / or abnormality of the underground buried pipe.

Here, the underground buried pipe (1) is partitioned by a predetermined section for the management and installation of the cable / pipe inside, the underground buried pipe measuring sensor cable 100 is underground buried in each of the divided section The embedding position and / or abnormality of the pipe 1 can be confirmed.

To this end, the underground buried pipe measuring sensor cable 100 has a length as long as the length of each divided section, the both ends of the signal of the sensors 700 installed in the cable 100 is read and required Connection terminals for supplying power can be connected. In addition, at both ends or one end thereof, a ring for connecting (eg, tying) an installation string (guide string) may be formed to move along the inner space of the underground buried pipe 1.

As the connection terminal, for example, a DB25 pin connector, a DVI connector, a parallel connector having a circular cross section, or the like can be used as the parallel communication cable terminal.

The sensor cable 100 for underground buried pipe measurement forms a bundle tube made up of lines through which signals or power are moved for the attached sensor 700.

The underground buried pipe measuring sensor cable 100 provides connecting slots to which the sensor can be attached at regular intervals in the longitudinal direction.

In the connecting slot, a connection protrusion is arranged to allow a signal line or a power line of a sensor to be connected to the line branch structure. The connection protrusion may perform a function of mechanically attaching the sensor inside the connecting slot while connecting the line and the sensor.

The structure of the connection protrusion and the connecting slots for each of the lines can be implemented in various forms, each form a separate embodiment of the present invention. It is obvious that the embodiments of the present invention include not only those described below, but also combinations of features of each embodiment which can be easily inferred from the description of the detailed description of each of the following embodiments.

The signals of the sensors 700 collected using the underground buried pipe measuring sensor cable 100 are analyzed by the control / signal processing apparatus 6-1, and the control / signal processing apparatus 6-1 is The analyzed signals can be used to indicate the location where the underground buried pipe 1 is embedded on the map on the display 6-2. The control / signal processing apparatus 6-1 and display 6-2 form a monitoring system for underground buried pipes.

FIG. 2A shows a cable with connecting slots according to the present embodiment, and FIG. 2B shows the connecting slot portion of the cable of FIG. 2A in detail.

In the cable 100 having connecting slots capable of attaching sensors at regular intervals in a longitudinal direction according to the illustrated embodiment, a signal line or a power line of the sensor is disposed in the cable lengthwise direction in the connecting slot. Connection protrusions 140 to 147 which allow connection to lines 120 to 129 in a branched structure; And a cover 180 that covers and protects the upper portion of the connection protrusion in a form overlapping with an outer circumferential surface of the cable without a sensor attached thereto.

As shown in FIG. 2A, the cable 100 having just formed connecting slots is shown only in slot-shaped covers 180 forming a cable outer surface in a direction perpendicular to the outer surface. That is, the cable with connecting slots implemented according to the present embodiment is provided without the sensors attached.

The cover 180 may be manufactured by injecting a plastic resin, attaching the cover in the form of a tape, or forming a coating on the outer circumferential surface of the slotted cable at a time.

When the user removes the cover 180 by using a cutter, a laser perforator, or the like, a plurality of connection protrusions 140 to 147 exist inside the slot from which the cover is removed, as shown. The user may attach the sensor by inserting one or two of the connecting protrusions into the fitting groove formed in the sensor. For sensors that need to be connected not only to + and-but also to reference ground, three connection protrusions can be connected to the fitting groove.

The illustrated connecting protrusion 142 has a Y-shaped cross point, but may have a T-shape.

The illustrated Y-shaped connecting protrusion 142 is a continuous conductor material as a whole, and includes a protrusion connected upwardly with a sensor, and a line fitting in which a part of a line is fitted to both side surfaces 122-1 and 122-2. Grooves 162 are formed. The end 301 of the line where the coating 302 is peeled off is fitted into the line fitting groove 162. The coupling may be performed by flattening or tightening the outside of the line fitting groove 162 to a peak shape, or by soldering / welding. In the figure, a trace 179 of flattening the outside of the line fitting groove 162 is shown.

The illustrated cable 100 forms a bundle tube consisting of lines 120 to 129 through which a signal or power for a sensor to be attached moves. The types of lines forming the bundle tube are not limited, and various ones. Can be.

For example, the lines 121 to 125, 128, and 129 may be signal lines that have relatively low voltage and current and require high sensitivity. If more protection against external noise is required, the signal line may have the form of a coaxial cable or an optical fiber.

For example, the lines 126 and 127 may be power lines having relatively high voltage and current and having physically sufficient dimensions.

For example, the illustrated line 120 may be a ground line providing a common reference ground voltage or a signal line required to minimize the influence of external noise.

By varying the color of the coating (insulation coating) of each of the lines 120 to 129, each line may be displayed to facilitate work. Preferably, it is advantageous to match the color indicated on each line 120 to 129 with the color of the connection protrusions 140 to 147 branching from the corresponding line 120 to 129.

For example, a separate color may be given to all the lines 120 to 129 constituting the bundle tube of the cable 100.

For example, the lines 120 to 129 constituting the bundle tube of the cable 100 are classified according to a use or a standard, each color is assigned a unique identification color, and a plurality of lines belonging to one classification are again unique. It may be given a sub-color or other identification means (eg numbers or alphabets printed on the cover). In this case, the identification color of the classification and the sub-unique color unique to the line may be striped, or the sub color may form a dot pattern. Here, the use may be for power signal transmission, signal transmission, reference grounding, reserve, etc., the specification is for high voltage, medium voltage, small voltage, large current, medium current, small current and large / It can be classified into a combination of medium / small voltage and large / medium / small current.

When the type of the line is a coaxial cable, as shown in Figure 3a, as shown in the connecting projection, a coupling step for connecting the coaxial cable or optical fiber may be formed on the outer surface. The sensor attached thereto is provided with a rotational fitting groove, the rotational fitting groove is rotated by a predetermined angle to complete the coupling with the connecting jaw.

The type of line may be an optical cable or a LAN cable. In the case of an optical cable, as shown in FIG. 3B, an optical splitter structure is formed at an intersection point of the branch structure, and the connection protrusion may be a line distributed in the optical splitter structure.

If the user can identify the lines provided in the cable by color or the like, for example, the user forms a line pair with two lines having the same specification while in use, and at one end of the cable, two lines forming each line pair The other end of the cable can be applied by connecting the input terminal of signal / power to one of the two lines and the output terminal to the other. This is how the sensors are connected to the cable with the connecting slots shown in FIG. 1.

However, when the application is performed by connecting only one sensor to each line pair, it may not be necessary to connect two lines constituting each line pair at the one end.

Depending on the implementation, the fabricated form of the cable itself connects the two lines constituting each line pair at one end of the cable, and connects the input terminal of the signal / power to one of the two lines at the other end of the cable, It may be provided with an input / output terminal for connecting the output terminal to the other one. In this case, at one end, a ring may be formed to connect (eg, tie) an installation string (guide string) to move along the inner space of the underground buried pipe.

The type and attachment form of a sensor that may be attached to a cable having connecting slots according to the spirit of the present invention may vary.

The cheapest sensor may be an acceleration / angular velocity sensor (using a geomagnetic field) used in a smartphone or the like. Longitudinal / latitude sensors can be applied to accurately locate the underground buried pipes.

For example, the sensor may be a camera sensor for capturing various images such as infrared rays and ultraviolet rays. In this case, the sensor may be a sensor integrated with a light emitting device for photographing.

For example, the sensor may be a sound receiving sensor, and may be a passive sensor that integrates the sound generator together or detects leaks or cracks.

For example, one sensor may be attached to each line forming the bundle tube. In this case, the monitoring system can very easily identify the sensor with each line.

For example, several sensors may be attached to one line forming the bundle tube. In this case, it is preferable to give a communication time slot for each sensor or to include an identification symbol in the communication packet so that the monitoring system can identify the signal of each sensor.

For example, the sensor may be attached by connecting a signal line and a power (power) line to each line forming the bundle tube, respectively.

For example, the sensor may be attached by connecting each line forming the bundle tube to a line in which a signal line and a power (power) line are integrated.

For example, the sensor may be attached to a signal line and / or a power line by connecting each line forming the bundle tube to a + line and a-line, respectively. In this case, two lines are allocated to one sensor.

For example, the sensor may be attached to a signal line and / or a power line by connecting each line forming the bundle tube to a + line and connecting the line to a common ground line of the bundle tube. have.

FIG. 4A shows a cable with connecting slots according to the present embodiment, and FIG. 4B shows in detail the connecting slot portion of the cable of FIG. 4B.

The cable 2100 having connecting slots for attaching a sensor at regular intervals in the longitudinal direction according to the present embodiment,

In the first embodiment, the connecting slots 2141 to 2154 protrude two by two with respect to one line 2121 to 2128 in which the signal line or the power line of the sensor is disposed in the cable lengthwise direction. Is distinguished from.

In addition, the cable of the present embodiment may also include a cover 2180 that covers and protects the upper region of the connection protrusions 2141 to 2154 in a form overlapping with the outer circumferential surface of the cable without the sensor attached thereto.

The covers 2180 and the connecting slots shown in the figure intersect with those formed at the top and those formed at the bottom, and the connecting slots formed at the top are connected only to the lines 2121 to 2124 located at the top of the bundle tubes of the cable. The protrusions 2141 to 2154 are exposed, and the connecting slot formed at the bottom thereof has a structure in which connection protrusions (not shown) are exposed only to the lines 2145 to 2148 located at the bottom of the bundle tubes of the cable.

In the present exemplary embodiment, two connection protrusions 2141 and 2151 protrude from each other with respect to one line 2121.

The two L-shaped connecting protrusions 2151 and 2141 shown in the drawing are conductor materials in which the whole is continuous, and has protrusions 2151 and 2141 having one end bent upward and connected to the sensor, and the other ends 2121-1 and 2121-2. ), A line fitting groove 2162 into which a part of the line is fitted is formed. The end 301 of the line from which the coating 302 is peeled off is fitted into the line fitting groove 2162. The coupling may be performed by flattening or flattening the outside of the line fitting groove 2162 to a peak shape, or by soldering / welding. In the figure, a trace 2179 of a pin shape outside the line fitting groove 2162 is illustrated.

Each line may be in an open state when no connection is made between the two connection protrusions 2141 and 2151. When the sensor is not mounted on the connection protrusions 2141 and 2151, the dummy is connected. It is preferable to use in a state. That is, since the default is dummy connected, the dummy is attached to the connection protrusion inside the slot without removing the slot cover 2180.

This embodiment is advantageous when the type of lines forming the bundle tube is an optical fiber, a coaxial cable, or a LAN cable.

For example, when the line is a coaxial cable, the connecting projection is implemented in the form of two coaxial cable connection ends as shown in FIG. 5, and the dummy 290 connects the two coaxial cable connection ends, in a default state. Coaxial cable lines can be made closed.

For example, in the case where the line is an optical fiber, in order to form the branching structure of the first embodiment, the connecting projection must be formed with a relatively expensive optical splitter structure (for example, the structure of FIG. 3A). By disconnecting and forming a connecting structure at each disconnected end, it is possible to more easily form the connecting projection. In this case, the optical splitter structure is formed in the sensor attached to the connecting projection, but the cable with the connecting slots of the present invention can be produced at low cost.

When the type of the line is a coaxial cable, an optical fiber, or a LAN cable, as shown in the drawing, the ends of each of the two unit lines are bent by the letter “A” to protrude upwards, and the outer surface of the line is connected to the coaxial cable or the optical fiber. Connecting jaw for the can be formed. The sensor attached thereto is provided with a rotational fitting groove, the rotational fitting groove is rotated by a predetermined angle (see Fig. 5), to complete the coupling with the connecting jaw.

As shown in the drawing, the dummy fitted to the connection protrusion in the state where the sensor is not attached is preferably provided with a rotational fitting groove which can be rotated and coupled to the connection jaw formed at the connection protrusion by a predetermined angle.

The cable with connecting slots according to the present embodiment may be FIG. 2A or FIG. 4A, and FIG. 6 shows the connecting slot portion of the cable of this embodiment in detail.

The cable having connecting slots for attaching a sensor at regular intervals in the longitudinal direction according to the present exemplary embodiment of the present invention maintains a continuous state without cutting each line in the connecting slot. ) Is a conductor rod, which has a form in which the terminal peak penetrates through the coating (coating) of the line and is electrically connected to the line 3121. However, only a difference exists in that the line 3121 is not physically disconnected, and its appearance is similar to that of the first embodiment in which the connection points of the connection protrusions are formed in a T-shape.

In addition, the cable of the present embodiment may also include a cover that covers and protects the upper portion of the connection protrusion in a form overlapping with an outer circumferential surface of the cable without a sensor attached thereto.

The connecting protrusion of the present embodiment may have a form in which one end of the connecting rod penetrates the coating (coating) of the line and is electrically connected to the line.

The process of forming the connecting protrusions 3141 of the present embodiment is simpler than that of the first embodiment, and may be performed in various ways.

For example, the conductive rod may be press-inserted into the coating of the line 3121 and then molded in a state of being electrically connected to the line 3121, or may be manufactured by curing the flexible material 3160 around the connection point. .

For example, drilling is performed by melting or drilling the coating of the branching region of the line 3121 to expose a part of the internal conductive wire, connecting the conductor rod to the exposed conductive wire by soldering or twisting, and T It can be molded by molding to maintain its shape or by curing the flexible material 3160 around the junction.

FIG. 7A shows a cable with connecting slots according to the present embodiment, and FIG. 7B shows the connecting slot portion of the cable of FIG. 7A in detail.

The cable 4100 having connecting slots for attaching a sensor at regular intervals in the longitudinal direction according to the present exemplary embodiment has covers 4180 covering and protecting the connecting slots and the upper portion of the connecting protrusion. It is distinguished from Example 1 by having a rectangular shape long in the longitudinal direction.

The shape of the connecting slot and cover has an advantageous effect to ensure the strength of the entire cable, but the remaining parts including the connection projections are similar to the case of other embodiments.

In the connecting slot shown in FIG. 7B, only the connection protrusion 4140 branched from the ground line 4120 and the connection protrusion 4141 branched from the first power / signal line 4121 are positioned to support one sensor. do. Each of the connecting protrusions 4140 and 4141 may be manufactured in the form of a T or Y shape as in the first embodiment, or in the same shape as in the third embodiment.

The form of the connecting slot and cover of the present embodiment is particularly useful in terms of convenience of manufacture and lightening of the cable strength when the connecting projection is the same as in the second embodiment.

Since the shape of the connecting slot and the cover of the present embodiment is intended to minimize cable strength deterioration due to the connecting slot, it is preferable that one sensor is attached to one connecting slot. In other words, one connecting slot under the one cover 4180 may be implemented to attach one sensor.

8 is a diagram illustrating a buried monitoring system capable of identifying a buried position of an underground buried pipe using a cable having a connecting slot according to the spirit of the present invention.

In the underground buried pipe 1 shown, the internal piping / wiring is removed or just constructed. Here, the underground buried pipe (1) shows the length (R) partitioned for each predetermined section for the management and installation of the cable / piping inside.

In the inner passage of the underground buried pipe (1) is arranged a cable with a connecting slot according to the spirit of the present invention, it is arranged in the inner passage by pulling one end of the cable with a predetermined winding device (9) Can be.

The other end of the cable is connected to a monitoring system 6, which can display the location of the underground buried pipe 1, as shown in FIG. 1.

FIG. 9 illustrates a method of measuring a buried position of an underground buried pipe using a buried monitoring system shown in FIG. 8 and a cable having a connecting slot according to the spirit of the present invention.

Method of measuring the buried position of the buried underground buried pipe, buried underground buried pipe (S110); Attaching necessary sensors to a connecting slot of a cable having a connecting slot (S120); Placing a cable to which the sensors are attached in an inner passage of the underground buried pipe (S140); Confirming the location of the underground buried pipe from the signals of the sensors (S160); And removing the cable having the connecting slot and installing the necessary wiring in the inner passage of the underground buried pipe (S180).

The length of the cable and the spacing between the connecting slots may have suitable values depending on the size of the underground buried pipe to which the buried position and / or abnormality is to be sensed.

For example, when the underground buried pipe is partitioned by a predetermined section for the management and installation of the inner cable / pipe, it is preferable that the total length of the cable has a value slightly longer than the length of the partitioned unit section. In this case, the interval between the connecting slots preferably has a value obtained by dividing the length of the divided unit section by a predetermined natural number. Here, the predetermined natural water may follow the number of sensors supported by the system for monitoring the underground buried pipe.

The distance between the connecting slots may be determined according to the type of sensor to be attached. For example, when the inside of the underground buried pipe is to be precisely observed by the camera sensor, the shooting range of the installed camera sensor may have a gap (comparatively close interval) that can be continued. For example, when it is necessary to check whether the underground buried pipe is leaked by the acoustic sensor, it may have a relatively sparse interval.

The step S120 may be performed by removing the cover of the cable with a cutter or a laser perforator and mounting a suitable sensor to the connecting slot from which the cover is removed.

When the location of the underground buried pipe finds a significant excretion error than the original design in the step (S160), find out the degree of adjustment of the buried position can be modified in the currently buried terrain, and correct the underground buried pipe position as determined to be correctable Construction can be done.

The step S140 may be performed by the winding device 9 of FIG. 8 pulling the one end of the cable (length: R) having the connecting slot and lengthening it along the inner passage.

Removing the cable with the connecting slot in step S180 may be performed by the winding device 9 of FIG. 8 continuously pulling one end of the cable so that the connecting slot exits the inner passage. .

Installing the necessary wiring in the inner passage of the underground buried pipe in the step S180, the winding device 9 of Figure 8 is pulled one end of the required wiring (length: R) is arranged long along the inner passage, This can be done in a manner fixed by the worker.

It should be noted that the above embodiment is for the purpose of illustration and not for the purpose of limitation. In addition, those skilled in the art will understand that various embodiments are possible within the scope of the technical idea of the present invention.

For example, a cable having a connecting slot according to the spirit of the present invention may be implemented in the form of a cable connecting a mobile communication repeater installed in a subway, a tunnel, or the like.
