Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a measurement line insertion apparatus for detecting leakage of a reservoir and a dam, and an installation method of the measurement line using the same.

The present invention relates to a measuring line inserting device for detecting the leakage of reservoirs and dams and a method of inspecting the measuring lines of the TDR measuring equipment in order to detect groundwater leaks such as reservoirs and dams. The present invention relates to a measuring line inserting device for detecting leakage of a reservoir and a dam which can be easily installed vertically in a perforation hole of a target ground and can easily maintain the installation state during a measurement period, and a method of installing the measuring line using the same.

In places where water such as reservoirs and dams are stored, water leakage becomes a serious problem.

Such water leaks are very difficult to visually identify due to the nature of the storage location, and accordingly, a sensor that detects leaks at a high cost is required to be installed in the entire area of the site. However, due to the installation cost of such a sensor, there are not many cases where a facility for detecting leakage is installed in a place where water exists.

Since water is recognized as an important resource, the loss of water by leaking water is a big economic problem, and it also causes the collapse of reservoirs and dams.

Meanwhile, TDR (Time Domain Reflectometry) is a device for grasping the discontinuous position of a cable and is generally used in the field of communication. On the other hand, TDR technology is being developed as an extension of application field, equipment for measuring water content of soil, ratio for measuring rock displacement, and equipment for measuring displacement of sloped ground.

The TDR measuring instrument measuring the water content of soil is one of the application fields of TDR technology. The TDR measuring instrument measuring the water content of the soil is composed of a measuring line buried in the ground, a TDR measuring device for generating electric pulses on the measuring line connected to the measuring line, (Also referred to as a TDR sensor), and a notebook computer connected to the TDR instrument to process and display data sensed by the TDR instrument.

The operation of the TDR measurement equipment is as follows.

When a TDR instrument generates an electrical pulse, the electrical pulse is transmitted down the ground along the measurement line. Because the dielectric constant of the water and soil in the ground is different, the localized capacitance is changed at the location where the groundwater is located, and the reflected waveform of the electric pulse appearing on the TDR meter changes. Therefore, it is possible to measure the moisture (water level) saturation of the groundwater stored in the ground by using the reflected wave of the electric pulse generated at this time by using a notebook computer.

In the prior art, in order to measure the state of each ground, a structure for installing the measuring line on the ground of the inspection target area is as follows.

The measuring line is made of a plastic material with good portability and a thin conductor wire inserted inside the sheath.

However, since the measurement line is fixed by injecting the standard yarn in the state that the measurement line is inserted into the boring hole along the boring hole as described above, the measurement line can not be positioned in a straight line along the boring hole. As a result, the groundwater level where the groundwater is actually located does not coincide with the length of the measurement line, which causes an error in measurement.

In order to solve the above-described problems, a vertical guide and a connector, which are inserted into the inner side of a measuring instrument of a TDR measuring instrument, are coupled by a stopper so as to firmly couple the vertical guide and the connector. It is possible to easily insert the measuring line into the perforation hole of the ground to be inspected in a vertical (straight line) state without bending and to detect the leakage of the reservoir and the dam which can be reused later, And a method of installing the measurement line using the same.

And FIG. 6 is a state in which the measurement line is installed using the measurement line inserting apparatus according to the present invention.

Before describing the measurement line inserting device of the present invention in detail, the TDR (Time Domain Reflectometry) described in the present invention is a general TDR measurement device used for measuring the water content ratio of the soil. As shown in FIGS. 1 and 6, the TDR measuring apparatus comprises a measuring line 10 embedded in the ground, a TDR meter 11 for generating electric pulses, and a terminal 12, which is a system such as a notebook computer. 12 and the TDR measuring instrument 11 are connected by a coaxial cable and the measuring line 10 is connected to the TDR measuring instrument 11.

Because the dielectric constant of water and soil in the ground is different, the capacitance changes in the part where the groundwater is located, and the reflected waveform of the electric pulse appearing on the TDR meter changes. Therefore, it is possible to measure the groundwater distribution level (level) of the ground through the terminal 12, which is a system such as a notebook computer, by using the reflected waveform of the electric pulse, . ≪ / RTI >

In the measurement line inserting apparatus of the present invention, the measurement line 10 for measuring the groundwater distribution for detecting the leakage point of reservoirs and dams by using the TDR measuring apparatus described above is installed vertically and horizontally on the ground to be inspected such as reservoirs and dams The vertical guide 20, the connector 30, the stopper 40, the stationary ring 50, and the roast cone 50, as shown in Figs. 2 and 4, .

The vertical guide 20 has a cylindrical inner hollow shape so that the measurement line 10 is inserted inward and inserted into a perforation hole S which is drilled deeper than the level of groundwater in the ground of the inspection object.

The vertical guide 20 is preferably formed to have a diameter corresponding to the inner diameter of the perforation hole S or smaller than the perforation hole so as to be easily inserted into the perforation hole S.

The vertical guide 20 is formed with an extending protrusion 21 at a predetermined height at a lower end thereof and an extended protrusion 21 formed in a shape of a vertical light guide having an outer diameter smaller than that of the vertical guide 20, And a plurality of vertical cuts 210 are formed in the extended projections 21 along the periphery.

If the height of the vertical guide 20 is to be further increased according to the depth of the perforation hole S of the inspection target ground, the vertical guide 20 may be screwed to the vertical guide 20 An extension pipe 20 'having threads at the upper and lower ends is formed, so that the height of the vertical guide 20 can be easily extended.

The connector 30 is cylindrical in shape so as to be installed at the lower end of the vertical guide 20 and has an inner hollow shape and an inner side in the shape of upper light lower end and has an inner diameter larger than the outer diameter of the extending projection 21 formed in the vertical guide 20 And is formed to have a predetermined size.

5A, the engagement between the connector 30 and the extension protrusion 21 can be firmly achieved by connecting the stopper 40, which will be described later, to the extension protrusion 21 to enlarge the diameter of the extension protrusion 21 The connector 30 and the vertical guide 20 are difficult to separate from each other. As shown in FIG. 5B, after the stopper 40 is separated, the diameter of the connector 30 is returned to the original state, The connector 30 and the vertical guide 20 can be separated from each other.

The stopper 40 is made of rubber or silicone material having elasticity and has a hollow portion for inserting the measurement line 10 and a flange portion 41 connected to the inside of the extension portion 21 at the lower portion.

The diameter of the flange portion 41 is formed to be a diameter corresponding to the inside of the extension portion 21 and a diameter of the flange portion 41 increases toward the lower portion. The diameter of the flange portion 41 decreases toward the lower portion Is formed to be larger than the inner diameter of the extending projection portion (21).

Therefore, the stopper 40 can be smoothly inserted into the extended projecting portion 21 by the flange portion 41 of the vertically downwardly lighted shape, and the stopper 40 inserted into the extended projecting portion 21 can be moved The extended protrusion 21 can be extended outward by the vertical cutout 210 even when the diameter of the extended portion 21 is larger than the inner diameter of the extended protrusion 21 as it goes down. 21 and the flange portion 41 is inserted into the elongated projecting portion 21 of the connector 30, the rigid locking engagement of the elongated projecting portion 21 and the connector 30 while the outer diameter of the elongated projecting portion 21 is expanded corresponding to the inner diameter of the connector 30 .

The connection of the measuring line 10 and the fixing ring 50 is performed by removing the covering line 101 at the lower end of the measuring line 10 to expose the lower ends of the conductive lines 100, It is preferable to connect them to each other in a binding manner.

The lobe cone 60 is configured to be fixed to the lower end of the connector 30 so that the lower end of the measurement line 10 is fixed and the vertical guide 20 can be easily inserted into the perforation hole S, And an upper central portion formed with a hook-shaped hooking ring 61 for hooking a stationary ring 50 connected to the lower end of the measuring line 10, A coupling pipe 62 having a predetermined diameter with a diameter corresponding to the lower inner side of the body 30 is formed and a wedge portion 63 having a narrower lower end than the body is formed at the lower side of the cylindrical body, Thereby facilitating the insertion of the perforation hole S into the through hole 60.

Therefore, in order to fix the measurement line 10, which is inserted into the vertical guide 20 and the connector 30 and the fixing ring 50 is connected to the lower end, to the upper end of the lost cone 60 When the lower end of the measurement line 10 is connected to the lost cone 60 by hanging the retaining ring 50 on the retaining ring 61 formed in the lost cone 60 and then the coupling tube 62 of the lost cone 60 is connected to the connector 60, And the lower end of the measuring line 10 is fixed to the lower portion of the connector 30 so that the lower end of the measuring line 10 is fixed.

In the measuring line inserting apparatus constructed as above, it is preferable that the vertical guide 20, the connector 30, the stationary ring 50, and the lost cone 60 except for the stopper 40 are made of a plastic material.

Hereinafter, a method for installing a measurement line using a measurement line inserting apparatus for detecting leakage of reservoirs and dams according to the present invention will be described in detail.

First, to measure the water saturation using the TDR measurement equipment, a perforation hole (S) is formed in the ground of the reservoir or the dam in the vertical direction deeper than the level of the groundwater.

Thereafter, the connector 30 is inserted into the lower end extending projection 21 of the vertical guide 20, the stopper 40 is inserted from the inside of the lower portion of the connector 30 to the inside of the extending projection 21, The flange portion 41 of the flange portion 41 of the flange portion 41 is pressed downward and the flange portion 41 is fitted to the inside of the extended projection portion 21 to expand the diameter of the extended projection portion 21, The measurement line 10 is inserted from the upper side of the vertical guide 20 to the lower end of the connector 30 and the lower end of the measurement line 10 is fixed to the stationary ring 50 When the stationary ring 50 is connected to the measurement line 10, the stationary ring 50 is connected to the retaining ring 61 of the loudspeaker cone 60, and the loudspeaker cone 60 is connected to the connector 30 And the measurement line inserting device is assembled so that the measurement line 10 is fixed inward by a method of fitting into the lower end.

(The measurement line 10 is formed to be longer than the depth of the perforation hole S, the upper side is exposed to the upper ground of the perforation hole S).

The measuring line inserting device in which the measuring line 10 is inserted is inserted into the perforation hole S with the lost cone 60 facing downward so that the measuring line 10 is vertically installed in the perforation hole S without bending.

When the measuring line 10 is inserted into the perforation hole S by using the measuring line inserting device, a pressure bar (not shown) formed longer than the vertical height of the vertical guide 20 is inserted into the vertical guide 20, The stopper 40 is disengaged from the extended protrusion 21 to release the locking engagement between the vertical guide 20 and the connector 30. [

The vertical guide 20 which has been unlocked from the connector 30 is taken out from the perforation hole S and is recovered so that the vertical guide can be reused later.

6, in order to eliminate a space between the measurement line 10 and the perforation hole S provided in the perforation hole S after the vertical guide 20 is removed, (Paper, sand, etc.) so that the measuring line 10 can be installed in the perforation hole S while maintaining a vertical state during the measurement period.

After the measurement line 10 is installed in the perforation hole S, the TDR meter 11 connected to the terminal 12 for measurement is connected to the measurement line 10 exposed by the upper ground of the perforation hole S Connect to the top to complete the installation of the TDR measurement equipment.

When electric pulses are generated in the TDR measuring instrument 11 for measuring with the TDR measuring instrument provided with the measuring line 10 as described above, electric pulses are generated along the conductor line 100 of the measuring line 10, And an electric field is formed in the measurement line 10 as electric pulses flow through the conductor lines 100. [

At this time, since the dielectric constant of water and soil is different, electric pulse is changed in a portion where the groundwater in the ground to be inspected is changed, and electric pulse reflected in the changed state is sensed by the TDR meter 11, By measuring the degree of moisture saturation stored in the soil to be inspected in the terminal 12 where the software is stored, it is possible to easily check the water leakage point in the soil to be inspected through the measured moisture saturation using the TDR measurement equipment.

After the measurement of the degree of moisture saturation is completed through the measurement line installed using the measurement line inserting apparatus according to the present invention, the TDR meter 11 and the terminal 12 are separated from the measurement line 10, The stopper 30, the connector 40, the stationary ring 50, and the lost cone 60, which are installed in the perforation hole S, It is preferable to bury it in the perforation hole S.

Meanwhile, the measuring line inserting apparatus according to the present invention is explained in the general description of the measurement of the distribution of groundwater for detecting the leakage of reservoirs and dams, but can be applied to various fields such as displacement measurement of rock masses and displacement measurement of sloped grounds.
