Description

Horizontal reservoir embankment leak detection and monitoring device {HORIZONTAL RESERVOIR DAM LEAK DETECTION AND MONITORING DEVICE}

The present invention relates to a horizontal reservoir embankment leak detection and monitoring device.

More specifically, a horizontal reservoir that detects whether or not there is a leak through a leak measuring unit inserted into the ground of the detection target, but by measuring the reservoir water level at the time when the leak occurs, thereby specifying the location of the leak according to the water level measurement. It relates to an embankment leak detection and monitoring device.

Recently, water leakage from reservoirs, dams, and other water storage areas has become a serious problem.

It is very difficult to check such leaks with the naked eye due to the nature of the storage place, and accordingly, there is a problem in that a leak detection sensor for detecting the leak at a high cost must be installed in the overall part of the place.

However, since the installation cost of such a leak detection sensor is relatively high, it is difficult to install a facility that detects leaks.

Nowadays, when water is recognized as an important resource, water loss due to leakage is bound to emerge as a big economic problem and also causes the collapse of reservoirs and dams, so studies on the technology to detect water leakage are being actively conducted.

On the other hand, TDR (Time Domain Reflectometry) is a device that detects the discontinuous position of a cable, and is a technology generally used in the communication field.

In addition, the application field of TDR technology has been gradually expanded and is being developed as a device that measures the water content of soil, a device that measures the displacement of rock mass, and a device that measures the displacement of sloped ground.

As one of the applications using TDR technology, the TDR measuring equipment that measures the water content of the soil is a TDR measuring instrument (aka, a TDR measuring instrument that generates electric pulses in the measuring line and the reflected wave reflected through the measuring line) and a measuring line buried in the ground. Also referred to as a TDR sensor) and a notebook computer connected to the TDR measuring instrument to process and display the data detected by the TDR measuring instrument.

The operation of these TDR measuring equipment is as follows.

When an electric pulse is generated by the TDR measuring instrument, the electric pulse is transmitted to the bottom of the ground along the measurement line. Since the dielectric constants of water and soil inside the ground are different, local capacitance changes in the area where the groundwater is located, and the reflected waveform of the electric pulses displayed in the TDR meter changes. Therefore, it is possible to measure the moisture (water level) saturation of the groundwater stored inside the ground using a laptop or a computer using the reflected waveform of the electric pulse generated at this time.

As one of the related technologies, Registration Patent No. 10-1990356 discloses a measuring line insertion device for detecting leaks in reservoirs and dams, and a method of installing a measuring line using the same.

To explain the conventional instrumentation line insertion device for leak detection in reservoirs and dams, and how to install a measurement line using the same, the measurement line of the TDR measurement equipment is drilled into the inspection target ground in order to detect groundwater leak points in reservoirs and dams. It is characterized in that it can be easily installed vertically and easily maintained during the measurement period.

To explain in detail the conventional measuring line insertion device for detecting leaks in reservoirs and dams, an extension protrusion inserted into a perforated hole formed in the ground of an inspection object, the outer diameter is reduced at the lower end, and formed at a predetermined height in the shape of an upper optical lower narrow, An inner hollow vertical guide having a plurality of vertical incisions around the extension protrusion; A connector having an inner hollow shape such that the extension protrusion of the vertical guide is inserted into the upper inner side, the inner side of which is shaped like an upper optical lower narrow, and the upper inner diameter is formed larger than the outer diameter of the extension protrusion; An inner hollow stopper formed with a flange portion in the shape of an upper and narrow beam in a lower portion so that the extension protrusion and the connector are firmly coupled to each other by being coupled to the inside of the extension protrusion of the vertical guide to which the connector is coupled; A vertical guide coupled by a stopper and a retaining ring connected to the lower end of the measurement line inserted into the connector; A locking ring is formed at the upper end to catch the fixing ring to which the measurement line is connected, the lower end is formed sharply, and the upper end is composed of a lost cone that is fitted to the lower end of the connector.

However, in the prior art, since the vertical guide is configured to be vertically inserted into the ground to be inspected, the detection area of water leakage by the vertical guide is narrow, so a large amount of vertical guides are applied to the ground to be inspected according to the size of the ground to be inspected. There is a problem that must be configured to be inserted.

The horizontal reservoir embankment leak detection and monitoring device according to the present invention measures the water level of the reservoir through the water level measurement unit 100, and detects whether or not there is a leak through the leak measurement unit 200 inserted into the ground of the detection target, It relates to a horizontal reservoir embankment leak detection and monitoring device capable of specifying the location of the water leakage according to the water level measurement by measuring the reservoir water level at the time when the water leakage occurs.

Hereinafter, a horizontal reservoir embankment leak detection and monitoring apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a side view showing a reservoir and an embankment in a horizontal reservoir embankment leak detection and monitoring device according to the present invention, and FIG. 2 is a view showing a schematic configuration of a horizontal reservoir embankment leak detection and monitoring device according to the present invention, 3 is a side view showing an example in which a horizontal reservoir embankment leak detection and monitoring device according to the present invention is installed, and FIG. 4 is a perspective view showing a water level measurement unit in the horizontal reservoir embankment leak detection and monitoring device according to the present invention.

First, referring to FIG. 1, the reservoir and the embankment will be described. The embankment 10 is for confining the reservoir, and by restricting water within a certain flow path, flooding is prevented, storms, tsunamis, and It refers to a civil engineering structure built by stacking soil and sand to protect coastal ports from waves.

As shown in FIG. 1, the embankment 10 is a clay layer 20 that is the center of the embankment 10, a first earth and sand layer 30 formed on one side of the clay layer 20, and a second earth and sand layer formed on the other side. It consists of 40.

In this case, the first soil layer 30 and the second soil layer 40 may be formed in a form in which the area gradually decreases from the bottom to the top, as shown in FIG. 1.

In this way, the horizontal reservoir embankment leak detection and monitoring device according to the present invention is installed on the embankment 10 to measure whether there is a leak, but by monitoring whether there is a leak according to the reservoir water level, so that the location where the leak has occurred can be specified. It is configured to include a water level measurement unit 100, a water leakage measurement unit 200, a control unit 300 and a central server 400.

The water level measurement unit 100 is provided on one surface of the first soil layer 30 to perform a function of measuring the water level of the reservoir, and includes a sensor unit 110 and an induction tube 120.

The water level measurement unit 100 is configured to allow the fluid in the reservoir to flow into the sensor unit 110 through the induction tube 120 and measure the water level in the sensor unit 110.

In this case, the water level measuring unit 100 may be configured to be immersed in groundwater as it is installed by being exposed to the outside of the first soil layer 30 as shown in FIG. 3.

The sensor unit 110 is provided on one surface of the first soil layer 30 and has a shape extending from the bottom surface of the reservoir to the upper side of the weir 10 to measure the fluctuating water level of the reservoir.

In this case, the sensor unit 110 for measuring the water level may be composed of a buoyancy type level sensor, a pressure type level sensor, or a weight measurement level sensor.

Here, the buoyancy level sensor is a method of detecting the level based on buoyancy according to the changing water level using a float or a displacer floating in the water by buoyancy, and the pressure level sensor is a method of detecting the level based on the buoyancy of the reservoir. By measuring the differential pressure at the bottom, it is a method of measuring the water level of the reservoir according to Pascal's law, and the gravimetric level sensor is a method of determining the level by measuring the liquid weight using a load cell.

Preferably, in the horizontal reservoir weir leak detection and monitoring device according to the present invention, the sensor unit 110 may be made of a pressure level sensor.

This pressure type level sensor has the advantage of being able to be used at high temperature and high pressure, and is suitable for measuring the water level of the reservoir exposed to the outside.

In this way, the sensor unit 110 composed of a pressure type level sensor is provided with a separate pressure port 111 at the bottom of the sensor unit 110, as shown in FIG. 3, and is connected thereto to measure a gauge pressure for differential pressure measurement. It may be configured to include the transmitter 112.

Accordingly, the sensor unit 110 may measure the gauge pressure to specify the level L (the water level in the reservoir).

The method of specifying the level (L) by measuring the gauge pressure can be obtained by the following equation.

(Where, L is the water level in the reservoir, P is the pressure, ρ is the density, and g is the acceleration of gravity.

When described with reference to FIG. 4, the guide tube 120 is provided in the form of an empty pipe and is provided to surround the sensor unit 110 inserted into the inner space, and from the bottom surface of the reservoir to the upper side of the weir 10. It is made in an extended form, and performs a function of allowing water in the reservoir to flow through the inlet hole 121 to contact the sensor unit 110.

In this case, the guide tube 120 may have a plurality of inlet holes 121 formed in the longitudinal direction of the long axis, as shown in FIG. 4.

Accordingly, in the process of changing the water level of the reservoir, the fluid having the same height as the water level of the reservoir is brought into contact with the sensor unit 110 through the plurality of inlet holes 121, so that the water level of the reservoir can be accurately measured.

5 is a plan-side cross-sectional view showing an example in which a filter unit is provided in the horizontal reservoir weir leak detection and monitoring device according to the present invention.

On the other hand, when the fluid of the reservoir flows into the sensor unit 110 through the plurality of inlet holes 121, there may be a problem in that various foreign substances included in the reservoir are introduced together.

Accordingly, the horizontal reservoir embankment leak detection and monitoring apparatus according to the present invention may be provided with a filter unit 130 to filter the fluid flowing through the inlet hole 121 according to design conditions.

When described with reference to FIG. 5, the filter unit 130 performs a function of filtering a fluid flowing through the inlet hole 121, and a trapezoidal wedge wire is twisted in a spiral shape to prevent water between the wires. It can be configured with a wedge wire screen that allows it to pass.

At this time, the gap gap (a) of the wire may be made of 40 ~ 60㎛.

Accordingly, by smoothly filtering foreign substances having a viscosity, the fluid from which the foreign substances have been filtered may flow into the sensor unit 110.

6 is a front cross-sectional view showing an example in which an air supply unit is provided in the horizontal reservoir embankment leak detection and monitoring device according to the present invention.

Meanwhile, a part of the foreign matter filtered by the filter unit 130 may be returned to the reservoir or the remaining part may be deposited, resulting in a problem of deteriorating performance.

Accordingly, the horizontal reservoir bank leak detection and monitoring apparatus according to the present invention may be provided with an air supply unit 140 for separating foreign substances accumulated in the filter unit 130 according to design conditions.

When described with reference to FIG. 6, the air supply unit 140 is provided inside the induction tube 120 and is provided in the space inside the filter unit 130.

That is, the filter unit 130 is provided in the form of a circular tube along the inner circumferential surface of the pipe-shaped induction tube 120 so that all fluid flowing into the plurality of inlet holes 121 is filtered, but the filter unit 130 in the form of a circular tube The air supply unit 140 may be provided in the inner space.

The air supply unit 140 serves to supply air from the inner space of the guide tube 120 to the filter unit 130 and may be connected to a separate air compressor.

Accordingly, the fluid flowing into the inner space of the guide tube 120 through the inlet hole 121 is formed by air supplied from the air supply unit 140, and the air bubbles rise and the filter unit (130) Contact with the side, in this case, as the air bubble bursts and an impact is generated, foreign matter attached to the outer circumferential surface of the filter unit 130 is separated by the impact.

In this case, the air supply unit 140 may be configured not to operate while the water level measurement unit 100 measures the water level of the reservoir.

This is a problem in that accurate water level information cannot be obtained because the pressure value may be measured differently by the air supplied from the air supply unit 140 in the process of measuring the water level of the reservoir through the sensor unit 110 configured with a pressure type level sense. In order to prevent this, the air supply unit 140 may be configured not to operate while the water level measurement unit 100 measures the water level of the reservoir.

Depending on the design conditions, two nozzles (not shown in the drawings) for supplying air may be formed.

One of the pair of nozzles supplies air forming air bubbles to the inner space of the guide tube 120, and the other nozzle supplies air of strong pressure to the bottom surface of the guide tube 120. By allowing the air bubbles to rise at a high speed and at the same time allowing the air of strong pressure to be discharged to the outside of the induction tube 120 through the inlet hole 121, foreign substances attached to the filter unit 130 can be separated more easily. can do.

7 is a side view showing a leak measurement unit in the horizontal reservoir embankment leak detection and monitoring device according to the present invention.

The leakage inflow pipe 210 is inserted into the ground of the second soil layer 40, and has one end open and the other end closed in the shape of a pipe.

As a plurality of such leak inlet pipes 210 are formed along the longitudinal direction of the long axis, which will be described later, when a leak occurs in the weir 10, the leak flowing into the second soil layer 40 is the leak inlet pipe. It is to be transferred to the storage tank 230 through (210).

That is, the leakage measurement unit 200 allows the leakage of water to flow into the leakage inflow hole 220 and is transferred to the storage tank 230 along the leakage inflow pipe 210 so that the leakage can be identified.

At this time, the leakage inflow pipe 210 is coated with one or more of an oily, water-soluble resin, glass powder, alkali metal compound and alkaline earth metal compound on the inner circumferential surface so that the leakage water flowing into the inside is easily transferred to the storage tank 230 Can be processed.

8 is a side view showing another example of a leak measurement unit in the horizontal reservoir embankment leak detection and monitoring device according to the present invention.

Depending on the design conditions, the leak inlet pipe 210 may be provided in a form inclined downwardly to the storage tank 230 to be described later and the adjacent water, when described with reference to FIG. 8.

This is to ensure that when water leaks through the leak inlet hole 220 formed in plural along the longitudinal direction of the long axis of the leak inlet pipe 210, it is smoothly transferred to the storage tank 230 by the inclination of the leak inlet pipe 210. By doing so, it is possible to prevent in advance the problem of not being able to detect whether there is leakage due to leakage.

9 is a plan view showing an example in which a leak inlet pipe is provided in the horizontal reservoir embankment leak detection and monitoring device according to the present invention.

Depending on the design conditions, the leak inlet pipe 210 may be provided in a form in which a plurality of leak inlet pipes 210 are connected to one storage tank 230 when described with reference to FIG. 9.

This is, as the plurality of leakage inflow pipes 210 inserted into the second soil layer 40 are arranged horizontally and spaced apart from each other, in addition to the water level information measured by the water level measuring unit 100, whether or not leakage occurs in a wide range. To be able to measure.

For example, when the water level of the reservoir is measured through the water level measuring unit 100, and when it is detected that water has been leaked through one or more of the leaking inlet pipes 210, the water level in the reservoir It is possible to specify the location of the leakage according to.

That is, by measuring whether or not leakage occurs in a wide range through a plurality of leakage inflow pipes 210, when leakage occurs, it is possible to know that leakage has occurred at the current reservoir water level, so that the height at which the leakage occurs can be specified. have.

10 is a front cross-sectional view showing a leak inlet pipe in the horizontal reservoir embankment leak detection and monitoring device according to the present invention.

A plurality of leak inlet holes 220 are formed in the long axis direction of the leak inlet pipe 210, and perform a function of allowing water to flow into the leak inlet pipe 210 according to whether or not a leak occurs.

At this time, the leak inlet hole 220 is formed in a number of the long axis length direction of the leak inlet pipe 210, as shown in FIG. 10, may be formed to be spaced apart from each other along the circumference of the leak inlet pipe 210. have.

Preferably, the leak inlet hole 220 is formed in a radial shape with respect to the central axis in the long axis length direction of the leak inlet pipe 210, but the opened space may be made to face the upper side of the leak inlet pipe 210.

Thus, when leakage occurs, leakage is allowed to flow through a plurality of leakage inlet holes 220 opened upward, but leakage is detected by preventing leakage of leakage flowing into the leakage inflow pipe 210 from being discharged to the outside. According to the accuracy can be improved.

Depending on the design conditions, the leak inlet pipe 210 may be provided with a filter unit 130 provided in the guide tube 120.

Preferably, the filter unit 130 in the form of a circular tube may be provided along the inner circumferential surface of the leak inlet pipe 210 to filter the leak water flowing into the plurality of leak inlet holes 220.

11 is a front cross-sectional view showing another embodiment of a leak inlet hole formed in a leak inlet pipe in the horizontal reservoir weir leak detection and monitoring device according to the present invention.

Depending on the design conditions, the leak inlet hole 220 may be configured to gradually increase in diameter toward the inside of the leak inlet pipe 210, as shown in FIG. 11.

Furthermore, when a leak occurs, it may be configured to transmit a specific location where the leak has occurred.

In this case, the control unit 300 may be provided with a separate communication module to wirelessly transmit the water level information and the leak information.

Accordingly, the control unit 300 measures the water level of the reservoir in real time, but when a leak is detected through the leak measurement unit 200, the reservoir water level at the time when the leak occurs is measured to determine the location of the leak. Make it possible to specify.

For example, in the case of rain, when the leak measurement unit 200 detects whether or not a leak has occurred in the process of increasing the water level of the reservoir over time, it may be specified that the leak has occurred at the corresponding height.

That is, the control unit 300 collects the water level information and the water leakage information in real time, so that the location of the water leakage can be specified.
