Description

Artificial recharge apparatus

The present invention relates to an artificial cultivation apparatus, and more particularly, to an artificial cultivation apparatus including a water collecting unit, a second filtering unit disposed outside the water collecting unit, and an artificial capillary wall disposed below the second filtering unit. will be.

In the artificial cultivation apparatus of the present invention, when the groundwater level of the groundwater is rapidly lowered, the water is in danger of inflowing into the space where the groundwater should be stored, or when the disaster is caused by flooding, the rainwater overflowing by closing the floodgate into the ground through the artificial capjawal Can be stored.

In addition, when it is judged that there is no disaster caused by drought or flood, muddy water including trees and rocks extracted by opening the gate is filtered while passing through the structure that filters rainwater and foreign substances (block of foreign substance inflow). It can prevent the pier and the river to be blocked. In addition, household waste (waste tires, styrofoam, cans, etc.) can also prevent pollution of the sea.

In Jeju Island, up to 1980, the groundwater level stored underground was higher than the seawater level, and the spring water was overflowing all over the coastline.

At present, due to the rapid urbanization and the rapid increase in the demand for water, the groundwater level has been lowered, and the spring water from the spring water has decreased drastically.

The main rock of Jeju Island is porous basalt, and the soil of the ground is made of fluffy volcanic ash so that rainwater penetrates underground well when it rains. In addition, some 6% of Jeju's land is formed by Gotjawal (Jeju dialect), which is an uneven terrain formed by the lava that is formed by large volcanic eruptions.

Gotjawal is a structure in which holes are drilled from the earth's surface to dozens and hundreds of meters underground, where warm water rises in winter and snow does not accumulate. do.

In particular, Gotjawal is a World Natural Heritage Forest Reserve, a unique form of terrain that can only be found in Jeju Island.

Jeju Island has a steep slope to the sea, centering on Baeknokdam, the crater of Halla Mountain, because Halla Mountain itself is Jeju Island.

As a result, it has a topographic structure that does not allow dams to store much water. In addition, the rivers of Jeju Island are steeply inclined, so the water overflows for a few hours during heavy rains or during the rainy season, but immediately falls into the sea. As a result, only a small amount of water penetrates underground.

Thus, rivers in Jeju Island overflow during the rainy season but remain dry in normal times.

Jeju Island makes various efforts to artificially cultivate rainwater that falls into the sea through rivers. Since floating leaves, household garbage (farming vinyl, etc.) are mixed, artificially cultivating water without separating foreign matters does not solve the problem of the area becoming a reservoir or a wetland.

Therefore, Jeju Island is looking for a way to artificially cultivate a small amount of water in several places as an inevitable alternative.

One of several methods is artificial reinforcement using rainwater collected from rooftops or ground structures.

Experts say that by 2020, when Jeju is a special self-governing province, the space for rain erosion will be insufficient due to explosive population growth and development (roads, construction) due to the increase in tourists, while the demand for water will explode. As a result, the water level is expected to drop rapidly.

In addition, the increase in water demand and rainfall patterns due to recent warming are also causing severe droughts and heavy rainfall.

In order to solve these problems, Jeju Island recently supports research and installation costs for artificial regeneration techniques in consideration of the public interest of groundwater artificial regeneration techniques suitable for the geological characteristics of Jeju.

As a result, a total of 42 artificial craft boats were installed by December 2003, six were under construction, and 400,000m3 was reclaimed annually.

Currently, groundwater recharged by groundwater reclamation technology utilizes rainwater collected from building roofs or ground structures.

However, the amount of water supplied to the groundwater by the groundwater cultivation technology is currently insufficient to prepare for water shortages to come.

In order to solve this problem, Jeju Island is seeking artificial cultivation in various ways, but by sending muddy water without separating rainwater and foreign matter, the foreign matter blocks Gotjawal, which eventually blocks the space where water can penetrate into the ground. There is a problem.

In addition, even if you try to artificially cultivate rainwater in the river by using Gotjawal, there is a double problem of making a waterway to a far place where Gotjawal is formed.

Therefore, the present applicant has filed a Korean Patent No. 879600 "Structure for separating rainwater and foreign matter" in order to solve the above problems.

In Korea Patent No. 879600, a structure for filtering large trees, large stones, large foreign objects and rainwater contained in water falling into the sea through a river, using a beam or a network structure on one water collecting part to remove rainwater and foreign matter After separating and inventing a method of storing in the ground, there is a problem caused by the precipitation of small floats, such as leaves or waste vinyl floating in the water, that is, there is a problem of preventing foreign matter from blocking the water seeps into the ground.

As shown in FIG. 1, the collecting part 100 is formed of a square bottom 120 and sidewalls 110 connected to the bottom 120 to form a space for collecting water.

The shape of the water collecting part 100 may be variously made into a rectangular cylindrical shape, a cylindrical shape, or the like according to the geographic conditions of the place where the water collecting part 100 is installed.

The water collecting part 100 is opened at an upper portion thereof to introduce water, and an outlet 170 and an outlet 131 are formed.

The water collecting part 100 has a primary space part 140 on which the incoming water primarily stays. The primary space part 140 refers to a space between the left wall 111 of the water collecting part 100 and the first partition wall 151 described later.

The outlet 131 is formed through the left front lower portion of the side wall 110 so as to communicate with the primary space 140. In detail, the outlet 131 is disposed between the left wall 111 of the water collecting unit 100 and the first partition 151 described later, so that the outlet 131 is the left wall 111 of the water collecting unit 100. And a middle lower portion of the first partition wall 151 to be described later.

The outlet 170 is formed on the upper right side wall 112 of the water collecting unit 100.

The artificial rehabilitation apparatus of the present embodiment includes a first partition 151 and a second partition 152 installed inside the water collecting unit 100.

The first and second partitions 151 and 152 are sequentially disposed to be spaced apart from each other. In detail, the second partition 152 is disposed on the right side of the first partition 151.

The first partition wall 151 separates the primary space portion 140 and the secondary space portion 180 where water stays secondary. The secondary space part 180 means a space between the first partition wall 151 and the second partition wall 152.

The second partition wall 152 separates the secondary space portion 180 and the tertiary space portion 190. The tertiary space part 190 refers to a space between the second partition 152 and the right side wall 112 of the water collecting part 100.

The upper end of the right side wall 112 of the first partition 151 and the collecting part 100 is installed to be lower than the upper end of the side wall 110 and the second partition 152 of the collecting part 100.

Accordingly, water flows through the upper ends of the first partition wall 151 and the right wall 112.

The second partition wall 152 is installed to form a bottom space portion 154 (indicated by an arrow) between the bottom 120 of the water collecting portion 100.

Thus, water is moved through the bottom space 154.

Auxiliary outlet 132 is formed in the front lower portion of the bottom 120 or the side wall 110 of the collecting part 100 between the first partition 151 and the right side wall 112 of the collecting part 100.

In detail, the auxiliary outlet 132 is disposed in the middle of the first partition 151 and the right side wall 112 of the collecting part 100.

Preferably, the auxiliary outlet 132 is disposed below the bottom space portion 154 that is the lower portion of the second partition 152.

Further, the bottom 120 of the water collecting part 100 is formed to be inclined to be higher toward the first partition wall 151. That is, the bottom 120 of the collecting part 100 is formed to be inclined to be lowered toward the center of the outlet 131 or the auxiliary outlet 132.

In addition, the bottom 120 of the collecting part 100 is formed to be inclined so as to be gradually lowered toward the front.

The first bent part 121 and the second bent part 122 are formed in the bottom 120 of the water collecting part 100 along the front and rear directions. The first bent part 121 and the second bent part 122 are formed in an arc shape concave downward. Due to the first curved portion 121 and the second curved portion 122, sand or small gravel is effectively guided to the outlet 131 and the auxiliary outlet 132.

As such, the first bends 121 and the second bends 122 are formed to be inclined at the bottom 120 so that sand or small gravel is effectively gathered, so that filtering is smooth, and sand and gravel are applied to the flow of water. Therefore, it can flow smoothly.

An upper end of the first partition wall 151, a lower end of the second partition wall 152, an upper end of the right wall 112, that is, a portion contacting with the water passing through are formed in an arc shape. As a result, the flow of water can be made more smooth.

As shown in FIG. 2, the artificial rehabilitation apparatus of the present embodiment further includes a foreign matter inflow blocking unit 160 installed above the water collecting unit 100.

The foreign material inflow blocking unit 160 is disposed to be inclined on the upper portion of the primary space part 140, and is disposed to be continuous to the river 400.

The foreign material inlet blocking unit 160 may be formed of an iron structure such as a beam or a network placed at regular intervals.

The beam of the foreign material inflow blocking unit 160 may be placed along the flow direction of the water, and a connection beam (not shown) may be placed and supported in the vertical direction of the water flow at the bottom thereof.

Due to the foreign matter inflow blocking unit 160, the first large volume of foreign matter, such as large stones or trees is filtered to be more effective filtering.

The catcher 100 is installed in an area where a natural drop is formed in the river 400.

If there is no drop formed area, artificially forms the drop to install the catchment unit 100, or as shown in Figures 2 and 3, to install the collecting unit 100 in the river 400 terrain. .

The collecting part 100 is installed in plurality along the river 400 through which the flowing water overflows.

A plurality of catching units 100 may be provided, and may include a first collecting unit 100a, a second collecting unit 100b, and a third collecting unit 100c. The number of installations of the collecting part 100 may be installed to be inclined from several tens of meters to several hundreds of meters along the river in proportion to the amount of water introduced.

The outlet 131a of the first collecting part 100a has a larger outlet cross-sectional area than the outlet 131b of the second collecting part 100b, and the outlet 131b of the second collecting part 100b has a third collection. Outflow cross-sectional area is formed larger than the outlet 131c of the water portion 100c.

The first collecting part 100a is disposed upstream of the second collecting part 100b, and the second collecting part 100b is disposed upstream of the third collecting part 100c.

The first collecting part 100a, the second collecting part 100b, and the third collecting part 100c are provided to share adjacent sidewalls 110 with each other.

The foreign substance inflow blocking unit 160 is formed long and disposed above the first collecting unit 100a, the second collecting unit 100b, and the third collecting unit 100c.

Water flowing out of the first collecting unit 100a flows into the second collecting unit 100b and water flowing out of the second collecting unit 100b flows into the third collecting unit 100c.

The first catcher 100a discharges 50% of the water introduced, the second catcher 100b discharges 25% of the introduced water, and the third catcher 100c discharges 12.5%.

By controlling the outlets 131a, 131b, and 131c by using (opening and closing) the left hydrograph 113 and the right hydrograph 114, which will be described later, the outflow amount may be adjusted.

The second filtering unit 200 is disposed on the right side of the collecting unit 100 and is disposed outside the collecting unit 100.

The second filtering part 200 may be provided with a panel having a plurality of holes or a mesh with a hole or a mesh structure formed therein, and sidewalls may be provided so that water does not overflow to the outside.

The second filtering part 200 may be disposed to be inclined, and may be formed to open the front to be pushed out to the stream 400 'by the flowing force of the water.

On the downstream side of the second filtering part 200, the joining guide part 210 is installed so that the water and the suspended matter passing through the second filtering part 200 smoothly join the stream 400 '.

The second filtering unit 200 may be changed in length or size to be proportional to the amount of water introduced.

Water discharged through the outlet 170 of the first catcher 100a, the second catcher 100b, and the third catcher 100c flows into the second filtering unit 200.

The suspended matter contained in the water flowing into the second filtering unit 200 is filtered through the second filtering unit 200.

As such, the present invention may secondaryly filter sand and gravel accumulated on the floor included in the water through the collecting part 100, and leaves or vinyl floating in the rain water through the second filtering part 200. Filtering can be made more effective by being able to filter out suspended solids such as and the like.

As shown in FIG. 4, the artificial capjawal 300 is located under the second filtering part 200.

Artificial cape Jawal (300) is formed in a tubular shape of the top is blocked, a plurality of water holes are formed in the top and all around.

Artificial capjawal (300) may be installed several or dozens in proportion to the amount of water introduced.

Furthermore, the artificial capjawal 300 has a smaller size than the water passage hole 301c formed in the portion exposed to the ground surface of the water hole 301b. That is, the water passage hole 301b formed in the upper portion of the artificial capjawal 300 is formed smaller in size than the water passage hole 301c formed in the lower portion.

In addition, the water passage hole 301b formed in the portion exposed to the ground surface of the artificial capjawal 300 has a larger size than the hole 200a formed in the second filtering part 200.

That is, the water passage hole 301b formed in the portion exposed to the ground surface of the artificial capjawal 300 is twice as large as the hole 200a formed in the second filtering part 200, and the portion exposed to the ground surface of the artificial capillary 300 is doubled. The water passage hole 301c formed in the portion in the ground of the artificial capjawal 300 is twice as large as the water passage hole 301b formed. As a result, when foreign matter passes through the second filtering part 200, the foreign material goes down into the ground without being blocked any more.

Artificial capjawal (300) is formed as described above is more effectively prevented the passage of the rainwater is infiltrated into artificial capjawal (300).

A gravel g having a larger size than the water passage hole 301b of the artificial cape wall 300 may be disposed between the artificial cape wall 300 and the second filtering part 200. Due to such gravel (g), the artificial capjawal 300 is stably supported, and at the same time, the artificial capjawal 300 is prevented from being blocked.

Cement layer (c) may be formed between the gravel (g) in the lower portion of the second filtering unit 200 and the ground (u) in which the artificial capjawal 300 is embedded. Due to this cement layer (c) artificial manjajawal 300 may be more effectively supported.

Further, the panel portion in which the hole 200a is formed in the second filtering part 200 may be detachably installed. Therefore, when it is necessary to repair the gravel (g) or artificial capillary (300) it can be easy to work by separating the panel portion in which the hole (200a) is formed in the second filtering portion (200).

In the case of Jeju Island, the groundwater is stored from tens to hundreds of meters above the ground.

Therefore, in the case of installing artificial capjawal (300), after drilling a hole of about 300mm ~ 500mm in diameter from the ground to the place where the groundwater is stored, the artificial capejawal (300) about 300mm ~ 500mm in diameter is inserted into the hole Install.

On the other hand, by attaching a water gate to the catchment unit 100 can open and close the water gate as needed.

The water may or may not be supplied to the second filtering unit 200 through the water gate.

The front left portion (between the right side wall 111 and the first partition 151) of the side wall 110 of the water collecting unit 100 may be installed to open and close to serve as the water gate.

The sluice includes a left sluice 113 and a right sluice 114, and an outlet 131 is formed in the left sluice 113 and the right sluice 114, respectively.

The left sluice 113 and the right sluice 114 are slidably mounted from side to side. That is, the left sluice 113 and the right sluice 114 are installed in a sliding manner.

When the water gate is opened, the distance between the left gate 113 and the right gate 114 is farther away, so that the space between the first partition 151 in the right wall 111 is opened forward. Therefore, when the water gate is opened, the water flowing into the water collecting unit 100 is not discharged to the discharge port 170, but is discharged all toward the water collecting unit 100 in front.

When the water gate is closed, the left water gate 113 and the right water gate 114 abut each other, and the front of the space between the first partition wall 151 is blocked from the right wall 111 (except the outlet 131). Therefore, when the water gate is closed, the water flowing into the water collecting part 100 is discharged to the outlet 131 and is discharged to the outlet 170 at the same time.

In the event of a severe drought or flooding, the floodgate is closed so that rainwater passes through the second filtering part 200 through the discharge port 170 and is artificially cultivated.

As shown in FIG. 6, the water gate is normally opened so that rainwater does not go to the second filtering unit 200, and immediately falls into the stream 400 across the second and third collection tanks 100b and 100c. To do that. In this process, the muddy water can be nature-friendly because the foreign material is filtered while passing through the foreign material inlet blocking unit 160 to prevent foreign substances from blocking bridge bridges and rivers and to filter out household waste that pollutes the sea.

In this way, the structure of the present invention to the role of filtering the foreign matter and the artificial cultivation role, or only to remove the foreign matter as necessary through the water gate can minimize the natural damage and at the same time prevent the disaster.

On the other hand, because the structure of the present invention is installed in the ground beneath the river along the inclined surface, only the foreign matter inlet block 160 is visible in appearance, so it is not a problem in aesthetic view, or if the artificial capjawal 300 is blocked or Rainwater does not overflow when the floodgate fails.

Hereinafter, the operation of the present embodiment having the above-described configuration will be described.

As large stones, twigs, refrigerators, sand gravel, leaves, or floats such as vinyl flow into the water collecting part 100 through the river 400, foreign matters are primarily bulky through the foreign matter inflow blocking part 160. Large stones or large trees) are filtered out. When the bulky foreign matter is not removed separately, it is pushed down along the foreign matter inflow blocking unit 160 by the flowing force of water and goes back down to the river 400 '.

The first filtered water falls into the primary space part 140 of the first catchment part 100a in a state in which muddy water, gravel, sand, and floating floats are mixed.

About half of the water introduced into the primary space 140 is discharged through the outlet 131, and the other half is sequentially introduced into the secondary space 180 and the tertiary space 190.

The process of filtering sand and gravel from the primary space part 140, the secondary space part 180, and the tertiary space part 190 is as follows.

Water in the primary space portion 140 includes suspended matter, sand and gravel, and the like, and a portion of the gravel and sand is precipitated by its own weight in the primary space portion 140. The precipitated gravel and sand are collected toward the outlet 131 due to the inclined bottom 120 and the first bent part 121 and is discharged together with the water to the outlet 131.

The water overflows the upper portion of the first partition wall 151 by the principle of leveling and moves to the secondary space portion 180.

Water in the secondary space portion 180 is moved to the tertiary space portion 180 through the bottom space portion 154.

In this process, the gravel and sand contained in the water are precipitated by their own weight. The precipitated gravel and sand are collected toward the secondary outlet 132 due to the inclined bottom 120 and the inclined second bend 122, and is discharged together with the water to the secondary outlet 132.

The water moved to the tertiary space portion 180 contains foreign substances such as floats and flows over the right side wall 112 of the water collecting portion 100.

In this manner, the water collecting unit 100 separates the heavier than water (gravel or sand, etc.) and the lighter than the water (leaves or vinyl, etc.).

The heavier than water falls to the second catching part 100b together with some muddy water according to the principle of falling down and then discharges to the river 400 'via the third catching part 100c in the same principle.

Water flowing into the right side wall 112 flows into the second filtering part 200 and finally passes through the hole of the second filtering part 200 after the suspended matter is filtered. If the filtered suspended matter is not removed separately, it is swept away by the flowing force of water along the inclined second filtering part 200 and floated to the river 400 '.

The filtered water is introduced through the water through hole of the artificial capjawal (300) installed in the island area, such as Jeju Island (1) is artificially cultured into the underground space where the groundwater (2) is stored.

Artificially enriched water in underground space can be recycled through groundwater development. Therefore, when the artificial rehabilitation apparatus of the present embodiment is applied, the lack of water in island areas such as Jeju Island (1) is fundamentally prevented.

In addition, by separating the rainwater and foreign matter to prevent the artificial capjawal 300 is blocked, artificial cultivation is possible to prevent the depletion of groundwater and to artificially cultivate the water of the river 400 is prevented disasters such as floods.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims .
