Description

AROUND MONITORING APPARATUS FOR GROUNDWATER MONITORING WELL OF FIXED TYPE AERATOR STRUCTURE}

The present invention relates to aeration apparatus fixed groundwater observation well radon monitoring apparatus, and more particularly, to an aeration apparatus fixed groundwater observation well radon monitoring apparatus that aeration is fixed and the intake air is varied.

Uranium (U) is distributed in the earth's crust by 2 to 4 ppm.

With 4.6 billion years of half-life from uranium 238, which accounts for 99.3% of the total uranium, to lead (Pb) 206, radon (Rn) 222 is generated in the course of spontaneous radiation decay.

Radon 222 produces alpha rays with alpha decay. Radon in the ground is heavier than air, but has the property to rise to the surface.

Radon's rise to the surface makes it an important tracer to solve a variety of geological problems such as uranium, geothermal and petroleum resource exploration, active fault detection, and earthquake and volcanic eruption predictions.

These radon rise towards the surface through crusts (faults, geological structures) as the crustal movements or crustal movements.

In addition, the radon content in the uranium-rich strata is naturally high.

Soil and well ground water are used to investigate radon content of the earth's crust. Until now, groundwater radon content investigation has been conducted using: 1) LSC (Liquid Scintillation Counter) by taking ground water samples from bore holes. 2) Analyze groundwater radon gas generated by degassing from groundwater, and analyze it with an alpha cup in a well (synonymous with a borehole).

The analysis of radon content in groundwater wells using water solubility, which is a water-soluble property of radon, is very useful for geologically exploring underground resources (uranium, geothermal and petroleum) and for predicting geological disasters (active faults, earthquakes, volcanic eruptions). .

Recently, various media in the country warned of the danger of radon emitting alpha rays, and it is required to establish an infrastructure that can easily and accurately measure radon in a living space.

In order to efficiently establish national radon management measures, radon measurement should be carried out on a national scale. Therefore, the selection of measuring points and numbers, the dissemination of measuring equipment, and the reliability of measuring methods and measuring equipment need to be secured. .

However, in order to measure the radon change dissolved in the groundwater, the groundwater was periodically collected and the radon change was measured in the laboratory.

At this time, when the groundwater is collected, a pump or a sampling device must be inserted into the groundwater well, and the radon change data measured by disturbing the groundwater every time the pump or the sampling device is inserted into the groundwater well has been unstable.

It is also possible to monitor radon changes by continuously pumping groundwater, but the hassle that managers must manage at all times or at all times, resulting in wasted energy and disturbances with other research data due to groundwater level drops. There was a problem.

In addition, if the intake pipe is located at a predetermined depth of the groundwater well, groundwater is sucked into the intake pipe according to the water level change, and there is a problem in that the device breaks down when it enters the radon monitoring device.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Prior to describing the present invention, the concept of measuring and using radon (Rn) and radon is described.Radon is a radioactive element that is caused by radioactive decay of lead, a product of uranium decay. It can occur naturally and be collected everywhere.

Radon is the daughter of radium (a change from the parent element due to radioactive decay), which is formed during the radioactive decay of uranium (U) to ultimately lead (Pb).

Thus, high levels of radon mean high levels of uranium.

Basically, every crust contains uranium, so when it is naturally radioactive, radon comes out.

Deeper crusts, such as the origin of rocks, such as deep magma and deep granite bodies formed by it, have relatively high levels of uranium originally contained, but are minimal on the surface.

However, if there are passages that can directly communicate with the core, such as faults, volcanoes, hot spots, and large joints, radon will be relatively more affected by uranium than surroundings.

Earthquakes are caused by these faults or volcanic activity.

Therefore, the moment the earthquake occurs is more affected by deeper uranium-rich substances, such as magma and hydrothermal water.

For example, if there is a fault, it will basically spill more radon along the gap than elsewhere, and this will lead to more gaps when the underground activity becomes active and the fault begins to move, or the fault associated with the fault. This will cause more of the magma, hot water, or uranium daughter elements originally contained in the deep rock.

In order to continuously and reliably monitor groundwater radon changes that provide significant data for predicting or interpreting climate change, the present invention provides a venting device at a specific depth of the groundwater well and the intake of radon-containing air above the ground surface. It is an object of the present invention to provide an aeration system fixed groundwater pipe measuring radon monitoring device in which the aeration position of the aeration vent is fixed and the intake position of the intake vent is changed in conjunction with the groundwater level.

On the other hand, since the present invention uses a groundwater well or other boreholes, it is obvious that the present invention is not limited to the use of groundwater wells.

1 is a perspective view showing the configuration of a buoy in the aeration apparatus fixed groundwater observation well radon monitoring apparatus according to the present invention.

Referring to Figure 1, aeration apparatus fixed groundwater observation well radon monitoring apparatus according to the present invention includes a pipe 410, buoy 400 having a buoy 420.

Here, the pipe 410 has a cylindrical shape through which the inside.

The buoy 420 has a cylindrical shape in which a hole through which the pipe 410 penetrates is formed.

The pipe 410 penetrates through the hole formed at the center of the buoy 420.

That is, the buoy 420 is hermetically adhered to the outer circumferential surface of the pipe 410.

Using such buoy 400, aeration apparatus fixed groundwater observation well radon monitoring apparatus according to the present invention is formed.

This will be described with reference to FIGS. 2 and 3.

Figure 2 is a cross-sectional view showing the configuration when the water level of the groundwater surface in the aeration apparatus fixed groundwater observation well radon monitoring apparatus according to the present invention.

2, the aeration apparatus fixed groundwater observation well radon monitoring apparatus 1000 according to the present invention is a blocking plate 210, a support pipe 220, a radon monitoring unit 300, buoy 400 and , An air inlet pipe 500, an air intake pipe 600, a width mechanism 700, a support 800, a weight 810, and a wire 900.

Here, the blocking plate 210 is formed on the upper surface of the pipe 410 and serves to seal the well 200 in the lower portion of the blocking plate 210.

The blocking plate 210 may further include air inlet pipes 500 to be described later and respective through holes for inserting the air intake pipes 600.

The through hole maintains the airtightness between the inside of the through hole and the outer surface of the air inlet pipe 500 and the air intake pipe 600 when the air inlet pipe 500 and the air intake pipe 600 are inserted.

In addition, the blocking plate 210 keeps the water level of the underground water level constant at all times.

The blocking plate 210 can maintain a constant air volume (Vair) between the groundwater surface and the blocking plate 210, the constant air volume is the main factor for calculating the radon concentration in the groundwater from the radon concentration in the air to be.

As such, the main factors for calculating the radon concentration in the groundwater from the radon concentration in the air include not only the above air volume but also the temperature of the groundwater, the electrical conductivity, the volume ratio of the groundwater volume and the air volume, and the like.

This factor is measured by a sensor of a sensor unit (not shown) or the like.

In addition, the aeration apparatus fixed groundwater observation well radon monitoring apparatus 1000 according to the present invention further includes an air intake pipe (600).

The air intake pipe 600 is a silicon tube that sucks air including radon discharged from groundwater to the radon monitoring unit 300.

The air intake pipe 600 is located above the outer surface of the pipe 410 so that one end is not immersed under the groundwater surface, the other end is connected to the radon monitoring unit 300 to be described later.

At this time, it is preferable to form a bellows shape between one end and the other end of the air intake pipe 600, which will be described later in the description of FIG.

The aeration apparatus fixed groundwater observation well radon monitoring apparatus 1000 according to the present invention further includes an air inlet pipe (500).

One end of the air inlet pipe 500 is inserted into the pipe 410 and is located below the groundwater surface, and the other end is connected to the radon monitoring unit 300.

In addition, in the aeration apparatus fixed groundwater observation well radon monitoring apparatus 1000 according to the present invention, the wire 900 is inserted into the pipe 410, one end of the wire 900, the wire 900 on the wall of the well 200 It further includes a support 800 to prevent the implantation.

In the present embodiment, for ease of explanation, the support 800 is formed in a cylindrical shape or a disc shape, but is not limited thereto. The wire 800 may be formed in any shape so long as the wire 900 is not implanted on the wall of the well 200. Irrelevant

On the other hand, the aeration apparatus fixed groundwater observation well radon monitoring apparatus 1000 according to the present invention is attached to the weight (810) to the wire (900).

The reason why the weight 810 is attached to the wire 900 is that the wire to which the weight 810 is attached passes through the pipe 410 and is always kept at a constant depth below the groundwater surface, thereby allowing buoys according to the level change of the groundwater surface. This is to prevent the 420 from being affected by the vertical movement.

Meanwhile, a sensor unit (not shown) such as a pressure sensor, a temperature sensor, and an electrical conductivity (EC) sensor may be attached to the wire 900 or the buoy 420.

When the sensor unit is attached to the wire 900 or the buoy 420, it is convenient to periodically remove the sensor from the well 200 and insert it into the pipe 410.

In the aeration apparatus fixed groundwater observation well radon monitoring apparatus 1000 according to the present invention, one end of the air inlet pipe 500 further includes an aeration apparatus 700.

By aeration of the aeration mechanism 700, radon in the groundwater flows into the air between the blocking plate 210 and the groundwater surface.

In addition, in the aeration apparatus fixed groundwater observation well radon monitoring apparatus 1000 according to the present invention, one side is supported by the drilling hole 100, the air inlet pipe 500, the wire 900, and the air intake pipe 600 ) And a support pipe 220 is collected on the other side and positioned near the center of the well 200.

The support pipe 220 serves to position the air inlet pipe 500, the air intake pipe 600, and the wire 900 near the center of the well 200, and the air inlet pipe 500 and The reason why the air intake pipe 600 and the wire 900 are positioned near the center of the well 200 is to prevent sensors of the sensor unit from being implanted on the well 200 wall.

Meanwhile, in the aeration apparatus fixed groundwater observation well radon monitoring apparatus 1000 according to the present invention, the other end of the air intake pipe 600 and the other end of the air inlet pipe 500 are connected to the radon monitoring unit 300.

By such a connection, the radon concentration of the air intake from the air intake pipe 600 can be monitored in the radon monitoring unit 300, and the air is supplied to the groundwater through the air inlet pipe 500 and the aeration mechanism 700 By aeration of radon, the radon in the groundwater is introduced into the air between the blocking plate 210 and the groundwater surface.

In particular, the monitoring unit 300 monitors such a rapid change in radon concentration when a sudden change in radon concentration occurs, such as when seawater enters from a beach or when there is a big impact such as an earthquake on the ground. Can be.

Figure 3 is a cross-sectional view showing the configuration when the water level of the groundwater surface in the aeration apparatus fixed groundwater observation well radon monitoring apparatus according to the present invention at the time of falling.

Referring to FIG. 3, in the aeration apparatus fixed groundwater observation well radon monitoring apparatus 1000 according to the present invention, when the water level of the groundwater level changes, the position of the aeration apparatus 700 is fixed and the position of the air intake pipe 600 is underground. It is changed with the buoy 420 in response to the water level change of the water surface.

That is, in the present invention, the width fitting 700 inserted into the pipe 410 is fixed, and the air intake pipe 600 whose one end is located above the outer surface of the pipe 410 has a buoy ( With 420.

In addition, in the aeration apparatus fixed groundwater observation well radon monitoring apparatus 1000 according to the present invention, the air intake pipe 600 is formed in a bellows shape between one end and the other end.

The reason why the one end and the other end of the air intake pipe 600 are formed in a bellows shape as shown in FIG. 3 is that when the water level of the groundwater surface is lowered, the air intake pipe 600 formed in the bellows shape is unfolded. To do so.

That is, when the water level of the ground water level fluctuates, the position of the aeration mechanism 700 is fixed, and the position of the air intake pipe 600 is fluctuated with the buoy 420 in response to the fluctuation of the water level and the bellows of the air intake pipe 600. The shape will be unfolded or folded.

At this time, the aeration apparatus fixed groundwater observation well radon monitoring apparatus 1000 according to the present invention, the distance between the groundwater surface and the one side of the air intake pipe 600 is maintained constant when the groundwater level changes.

That is, when the water level of the groundwater surface decreases, the bellows shape between one end and the other end of the air intake pipe 600 is expanded, and the air intake pipe 600 attached to the pipe 410 is also lowered together.

Therefore, the distance between the groundwater surface and one side of the air intake pipe 600 is kept constant.

As a result, groundwater does not flow into the air intake pipe 600.

This is the conventional ground water flows into the air intake pipe 600 has the effect of solving the problem that the radon monitoring unit 300 caused a failure.

Hereinafter, the operation relationship of the aeration apparatus fixed groundwater observation well radon monitoring apparatus 1000 according to the present invention.

An air including radon introduced from the groundwater is located between the blocking plate 210 and the groundwater surface, and the air is inhaled through the air intake pipe 600 to move to the radon monitoring unit 300.

The radon monitoring unit 300 supplies air through the air inlet pipe 500 after measuring the radon concentration in the moved air.

At this time, the amount of air intake through the air intake pipe 600 and the amount of air supplied through the air inlet pipe 500 is the same.

The supplied air moves through the air inlet pipe 500 to be aerated by the aerator 700.

By the aeration of the aeration mechanism 700, radon of the groundwater again flows into the air between the blocking plate 210 and the groundwater surface.

Radon in the groundwater is again introduced into the air between the blocking pipe 210 and the water surface.

By such an operation, the radon monitoring unit 300 of the aeration apparatus fixed groundwater observation well radon monitoring apparatus 1000 according to the present invention has the effect of long-term continuous and stable monitoring of the change in groundwater radon.
