Description

Drain structure of artificial recharge

The present invention relates to a drainage structure for artificial reinforcement, and in particular, the primary pipe artificially reinforces the water underground and a plurality of through-holes are formed on the outer circumferential surface, and having a smaller diameter than the primary pipe, It relates to an artificial replenishment drainage structure comprising a secondary pipe disposed and in communication with the through hole.

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.

However, due to the rapid urbanization and the rapid increase in demand for water, the groundwater level is lowered, leading to a sharp decrease in the spring water from which spring water flows.

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 is thrown into the sea through rivers. Of course, because the leaves and living garbage (farming vinyl, etc.) floating in the water is mixed, if the artificial recultivation of water without separating foreign matters, the area does not solve the problem of immediately becoming a reservoir or a wetland.

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. Therefore, it is expected that the groundwater level will drop rapidly and ground subsidence will begin.

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

In particular, such damage cases are ground sedimentation in 50 cities, including Beijing, China, and as a result of the ground sedimentation, 300 times the area of Yeouido was severely accumulated 116cm. As a countermeasure, groundwater was secured through a rainwater collection facility or a wastewater purification facility. China's People's Daily Hardening Times reported that it is considering artificial underground irrigation.

In order to solve such a problem, 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, by December 2003, six sites were constructed for the purpose of installing a total of 42 artificial craft boats, and 400,000㎥ was used to reclaim groundwater annually. However, the problem is that the installation site of the artificial craft boat has no source of pollution. Due to the regional characteristics of Jeju Island, which cannot be installed in the area (it has a steep slope), it is inevitable that it is installed around agricultural fields that are farming, and agricultural wastewater from agricultural lands, golf courses, and livestock farms In addition, the groundwater is contaminated and the amount of water to raise even the method of general artificial wells (reservoirs) currently promoted by Jeju Island is too small to prepare for the explosive water shortages that will increase in the future such as fundamental ground subsidence. It is not enough to be in a state.

In order to solve this problem, Jeju Island is seeking artificial cultivation of using Gotjawal in various ways.However, in order to use Gotjawal, waterways and reservoirs must be made to the far place where Gotjawal is formed. The problem was not solved.

In particular, in the case of heavy rains, huge amounts of soil and hundreds of thousands of trees are washed away by landslides and all kinds of household garbage such as whole houses. The terrain is changed due to the disappearance of a whole village by soil and garbage.

In addition, severe droughts and excessive groundwater development have resulted in ground subsidence in some countries, with devastating consequences all over the world.

Accordingly, the present applicant has filed a Republic of Korea Patent No. 10-0879600 "Structure for separating rainwater and foreign matter" in order to artificially cultivate the rainwater in the process of solving the above problems.

Republic of Korea Patent No. 10-879600 is a structure for filtering large trees, large stones, large foreign objects and rainwater contained in the water falling into the sea through the river as a rainwater and a mesh structure using a single beam or net structure on one catchment part. The inventors invented a method of separating foreign matter and storing only rainwater in the ground, but the problem caused by the precipitation of floating matter such as leaves or waste vinyl floating in the water, that is, artificial goatjawal, which is a space where water penetrates into the ground, Problems may occur because of

Applicant has filed Patent No. 10-1047112 to further solve the above problems.

In Korean Patent No. 10-1047112, filtering is made to separate living garbage such as leaves and waste vinyls, which are floated in water more than 5mm, and complements the artificial vessels (artificial cape ash) to prevent the damage caused by heavy rain. It was a structure that was able to resource the overflowing water.

Second, the filtering part to filter out the floating matter (living garbage such as twigs and vinyls) floating in the water contained in the rainwater

Third, the filtering part for filtering soil and gravel

Fourth, artificial cruise ship (artificial Gotjawal)

However, the above-mentioned supplements filed by the applicant were regarded as general filtering in the process of being examined, and some pending decision was made.

The problem, however, is that there are no alternatives and alternatives to artificially cultivate more than a few hundred tons of rainwater that are thrown into the sea, causing enormous damage during heavy rains around the world. It is the greatest disaster on mankind.

Therefore, the above filtering systems are generally used only for artificial cultivation, not for filtering trash, and should be viewed as a set structure in which the system itself cannot be operated if any one filtering is omitted.

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

For reference, among the configurations of the present invention to be described below, the same configuration as the prior art will be referred to the above-described prior art, and a detailed description thereof will be omitted.

As shown in Figures 1 to 20, the reservoir filtering system for artificial regeneration of the present embodiment, the sand collecting unit 210 for depositing the sand contained in the water, and passes through the sand collecting unit 210 to the top A water is introduced, and includes a filtering unit 230 for filtering the introduced water, and artificial cultivation drainage units 300c and 300d for artificially cultivating the water passing through the filtering unit 230.

The reservoir filtering system for artificial cultivation of the present embodiment further includes a main filtering unit 100 at the front end. That is, only sand, gravel, and some rainwater that are heavier than water among the water passing through the main filtering unit 100 are introduced into the reservoir filtering system (FIG. 18) through the delivery pipe 137 of this embodiment.

The main filtering unit 100 is installed to be inclined in the stream so as to continue in the river.

For example, the main filtering unit 100 may be installed in the middle of a river.

The main filter 100 includes a large stone filtering unit 110 for filtering large stones and a first filter for filtering large foreign substances having a large volume disposed downstream of the large stone filtering unit 110 ( 120 and a second filter 130 disposed below the primary filtering unit to filter sand and gravel, and a secondary filtering unit 140 and a secondary filtering unit 140 to filter out floating matters floating in water. It includes an artificial cultivation drainage portion (300a, 300b) for artificially cultivating a water.

Large foreign matter filtering unit 110 serves to filter large stones, etc., heavier than the water contained in the water flowing from the river.

Large foreign matter filtering unit 110 for filtering a large stone is formed with a plurality of cylindrical protrusions 111 at a 50cm interval on the bottom of the channel. The plurality of protrusions 111 are arranged in a “∧” shape so that the central portion thereof faces the upstream of the stream.

On both sides of the protrusion 111, a foreign matter collection space 112 is formed so that a large stone of 50 cm or more can be collected.

The foreign matter collecting space 112 is formed to communicate with the water channel.

When the water passes through the water channel through the large foreign matter filtering unit 110, 50cm or more large stones are caught by the protrusions 111, and the filtered large stones, etc., are arranged in a “으로” shape. It is naturally guided to the foreign matter collection space 112 by. Due to this, the filtered large stone can be easily removed by the manager, it is possible to prevent the damage of other structures disposed downstream, the stone of 50cm or less is connected to the river through the protrusion 111 and the outlet 124 It is collected in the waterway 150.

The primary filtering unit includes a first filter 120 and a second filter 130 in which water passing through the first filter 120 falls.

The first filter 120 is provided with a width similar to the width of the river. Through the first filter 120 serves to send rainwater containing a large volume of sand and gravel of less than 5cm to the second filter 130, the first filter 120 is 5cm or more of household garbage and It filters out large foreign objects such as whole trees.

The first filter 120 is disposed above the second filter 120, and is more stably supported.

The first filter 120 is provided with guide walls 121 for forming channels in both sides.

The first filter 120 is a panel filter 122 for filtering between the guide wall 121 on both sides.

The panel filter 122 has a drain hole having a diameter of 5 cm through which water can pass.

Further, the drain hole formed in the panel filter 122 is tapered to be formed larger toward the bottom. That is, the drain hole formed in the lower portion of the panel filter 122 may have a diameter larger than 5 cm. As a result, foreign substances such as gravel or sand introduced together with the water can be passed without jamming.

The panel filter 122 is provided in a plate shape and may be provided with a concrete panel having a thickness of 15 cm.

The panel filter 122 is divided into several pieces with a small size, and the divided panel filters 122 are stably supported by the panel support 123.

The panel support beam 123 forms a skeleton so as to surround the outside of the panel filter 122, and a mounting groove in which the panel filter 122 is seated is formed on the upper surface thereof, so that the position of the panel filter 122 is stably Can be fixed.

As described above, the panel filter 122 is divided into a plurality of parts, and thus only a damaged part may be replaced in case of breakage, thereby reducing the maintenance cost.

Downstream of the first filter 120, a large foreign matter discharge port 124 is formed.

Large foreign matter discharge port 124 is discharged large foreign matter filtered through the first filter 120.

Furthermore, the guide wall 125 is formed in the first filter 120 so that the large foreign matter is effectively moved to the large foreign matter discharge port 124.

The large foreign matter discharge port 124 communicates with the left side of the stream connection channel 150 described below.

Therefore, the large foreign matter is discharged to the large foreign matter discharge port 124 is collected on the left side of the river connection channel 150, or floated to the river with the water. This effectively prevents the accumulation of large foreign matter on the first filter 120.

The second filter 130 has a water collecting tank-like channel formed at least three times wider than the width of the river.

The second filter 130 is formed so that the upper part is opened, and muddy water including gravel and sand of 5 cm or less passing through the first filter 120 directly falls into the second filter 130.

The second filter 130 is disposed on the first partition 131 spaced apart from the bottom of the water channel, and the second partition 132 disposed downstream of the first partition 131 and having a height lower than that of the first partition 131. ). The first partition 131 and the second partition 132 are arranged in pairs, and a plurality of spaces are formed in the second filter 130. In the present embodiment, six space parts may be formed.

Most of sand, gravel and muddy water passing through the first filter 120 fall in one space part, and muddy water flows sequentially from one space part to six space parts due to the nature of water to be leveled. That is, the water in the one space portion flows through the first partition 131 and the second partition 132 sequentially from the one space portion to the six space portion.

As described above, in the process of muddy water, heavy gravel and sand sink to the bottom.

The bottom of the second filter 130 is formed to be inclined toward the first partition 131 so that the height of the floor is gradually lowered, so that the gravel and sand that has sunk to the bottom are effectively collected under the first partition 131.

Sand and gravel outlets 136 are formed on the side walls of the second filter 130 so that the gravel and the sand sinking to the bottom can be effectively discharged, and the sand and gravel outlets 136 are provided with the respective first partition walls 131. Each is disposed so as to correspond to the position. Outlet valve 133 is installed in the sand and gravel outlet 136. Each outlet valve 133 is connected to the delivery pipe 137, the gravel and sand collected by the water pressure is sent to the sand collecting unit 210 through the outlet valve 133 with some muddy water.

The role of the outlet valve 133 may control the artificial flow rate of the artificial cultivation drainage parts 300a and 300b of the main filtering part 100 and the artificial cultivation drainage parts 300c and 300d of the sand collecting part filtering part.

 An outlet 134 is formed at an upper portion of the second partition 132 disposed downstream of the second filter 130 to allow water to flow in a width similar to that of the stream.

The outlet 134 serves as a channel for sending the water filtered by the primary filtering unit (the first filter 120 and the second filter 130) to the secondary filtering unit 140.

At this time, the muddy water passing through the primary filtering unit to the secondary filtering unit 140 includes wood debris and floats floating in water of 50 mm or less.

Furthermore, a water gate 135 is provided at the second partition 132 disposed downstream of the second filter 130 so as to be disposed at the side of the outlet 134. The sluice gate 135 is formed at a lower height than the outlet 134, and when the sluice 135 is opened, the water does not flow into the outlet 134, but only water flows through the sluice 135.

Sluice gate 135 means a flow rate control device that can be opened and closed.

In addition, the second barrier 132 is provided with a second floodgate 138 to be disposed at the other side of the outlet 134. The second sluice gate 138 is disposed upstream of the large foreign matter discharge port 124. The second floodgate 138 is formed to have a smaller cross-sectional area than the floodgate 135.

The role of the second sluice 138 is when a large amount of large foreign matter, such as when a lot of trees are pulled down when a landslide, etc., large foreign matters are accumulated in the stream connection channel 150 through the outlet 124 Since foreign matters may not be smoothly discharged, in this case, the second floodgate 138 may be opened to send large foreign matters down to the river through the power of water to smoothly discharge the foreign matters.

Downstream of the second filter 130, a river connection channel 150 is formed to have a width similar to that of the second filter 130. The stream connection channel 150 connects the second filter 130 and the downstream of the stream.

When the water gate 135 is opened, the water passing through the second filter 130 flows into the right side of the stream connection channel 150 and flows out into the stream downstream.

The initial inflow of water from rivers may include livestock wastewater, such as agricultural land, golf courses, and pesticides from livestock farms.

By opening the water gate 135, the contaminated water may be prevented from entering the filtering unit 140 through the outlet 134.

The secondary filtering unit 140 is formed to have a width similar to the width of the river, and serves to filter out suspended matter such as leaves of 5 mm or more contained in the muddy water.

The secondary filtering unit 140 is the first end 140a disposed at the most upstream, the second end 140b disposed downstream of the first end 140a and formed at a height lower than the first end 140a, and It is disposed downstream of the end 140b and includes a third end 140c formed at a height lower than the second end 140b.

The first end 140a and the second end 140b include a first filter 141 and a second filter 143 disposed below.

The third end 140c includes a first filter 141.

That is, the water passing through the first end 140a and the second end 140b is artificially cultured through the second filter 143 after passing through the first filter 141, and the water passing through the third end 140c is first It is artificially cultured immediately after passing through the first filter 141.

The first filter 141 is provided in a plate shape in which a plurality of through holes serving as drain holes are formed.

The first filter 141 is divided into a plurality and may be provided of stainless steel having a thickness of 5 mm.

Each end has a concrete beam 142 supporting the first filter 141.

The concrete beam 142 forms a skeleton so as to surround the outer periphery of the first filter 141, and a seating groove in which the first filter 141 is seated is formed on an upper surface thereof, so that the position of the first filter 141 is It can be fixed stably.

The suspended matter filtered through the first filter 141 remains on the upper part of the first filter 141. The suspended matter is pushed toward the river by the flowing power of the water without being cleaned separately and gradually accumulated in the river.

Through the second filter 143, before the artificial cultivation of muddy water including suspended matter (such as leaf debris and trash) within 5 mm passing through the first filter 141, the foreign matter is prevented from blocking the fine body of water in the soil described below. Do not

The second filter 143 includes a sponge 144 having an inclined surface 145 or a cloth 144a having good water absorption, and a bracket 146 supporting the sponge 144 or the cloth 144a.

The sponge 144 is formed in a rectangular plate shape, and the inclined surfaces 145 are formed on the left and right sides so that the heights of the centers of the upper and lower surfaces are the highest.

Alternatively, as shown in Figure 14a, the water may be formed in a cloth-like shape that is well absorbed onto the umbrella-shaped frame.

In this way, the inclined surface 145 is formed on the upper and lower surfaces of the sponge 144, there is an advantage that can be turned over and reused periodically.

In the dry season, the sponge 144 may be flipped immediately, and in the rainy season, even when water flows, the water gate 135 may be opened to change the flow direction of the water, and then the sponge 144 may be turned over. After inverting the sponge 144, the water gate 135 may be closed again to allow water to pass through the first filter 141 and the second filter 143.

Furthermore, a spring may be built in the sponge 144 to compensate for the elastic force.

The bracket 146 is formed of a concrete material, forms a skeleton so as to surround the outer periphery of the sponge 144, and a seating groove in which the sponge 144 is seated is formed on the upper surface, so that the position of the sponge 144 is stable. Can be fixed.

In addition, the bracket 146 is formed with a collecting path 147 for collecting the foreign matter dropped along the inclined surface 145.

The collection path 147 may be formed to be disposed on both sides of the sponge 144 in the direction in which water flows.

Due to the sponge 144 and the collecting passage 147, foreign substances such as leaf debris and garbage fall on the surface of the sponge 144 through the first filter 141, and then bounce by the water falling again. 144) to the U-shaped collection 147 below.

After the foreign matter is moved through the collecting path 147, the foreign matter collecting part 148 disposed downstream of the second end 140b via the foreign matter outlet 149a of the first end 140a is collected and the secondary filtering unit ( It is discharged to the stream connection channel 150 through the foreign matter discharge port 149 formed to communicate with the foreign matter collection unit 148 on the sidewall of the 140 and exits to the river. As described above, foreign matters do not precipitate, so the sponge 144 is not blocked.

In addition, the muddy water falling through the first filter 141 of the secondary filtering unit 140 to the second filter 143 includes only floating matters such as wood chips of 5 mm or less and no sand, so the second filter has no sand. Since (143) is no longer blocked, it can be effectively filtered out.

Therefore, the water injected into the artificial cultivation drainage path 300a through the second filter 143 is injected only with pure muddy water.

The secondary filtering unit 140 is formed with a discharge port 149b to communicate with the foreign matter collecting unit 148 and the third end 140c.

The role of the outlet 149b is that the second filter 143 of the first end 140a and the second end 140b is blocked or flows out of the outlet 134 rather than water absorbed into the ground through the artificial culture drainage 300a. When the amount of water becomes large, the overflowed water is collected at the three ends 140c through the outlet 149b, and then artificially cultured into the aquifer through the artificial culture drainage 300b.

An artificial cultivation drain 300a is connected to the first end 140a and the second end 140b of the secondary filtering unit 140, and an artificial cultivation drain 300b is installed at the bottom of the third end 140c. .

Primary pipe 310 has a plurality of through-holes 311 formed on the top and side.

The secondary pipe 320 is installed on the inner wall of the primary pipe 310.

Preferably, the secondary pipe 320 is installed only in the portion disposed in the soil (G) in the primary pipe (310). That is, the secondary pipe 320 is not installed in the upper portion of the primary pipe 310 that is exposed outside the (G).

The inlet 321 of the secondary pipe 320 faces upward and the outlet 322 faces the pipe side. Therefore, the secondary pipe 320 is formed such that the lower end is bent.

The secondary pipe 320 is provided such that the inlet 321 is disposed 10 cm or more above the through hole 311 through which the secondary pipe 320 communicates.

The role of the secondary pipe 320 is that rainwater is also cultivated through the inlet 321 and the outlet 322 when the rainwater descends to the ground through the through-hole 311 of the primary pipe 310 as well as another The role of the secondary pipe 320 is to prevent backflow due to the nature of the water to reach the horizontal, so that water or soil outside the primary pipe 310 does not flow down to the aquifer through the pipe 310 artificial cultivation The surrounding area of the place where the dragon pipe is installed can be prevented from sinking.

Inside the primary pipe 310, a tertiary pipe 330 through which air passes during artificial cultivation is installed. The tertiary pipe 330 may be provided as a cylinder having a diameter of 50mm smaller than the primary pipe 310.

The tertiary pipe 330 is disposed at the center of the primary pipe 310.

The upper end of the tertiary pipe 330 is installed to pass through the primary pipe 310.

In addition, when the artificial cultivation drainage portion (300a, 300b, 300c, 300d) is installed in the sump, the upper end of the tertiary pipe 330 is protruded from the bottom of the sump or the height of the secondary filter portion secondary filter 143 so as not to be submerged in water. Install high until

The upper end of the tertiary pipe 330 is bent in an "n" shape at the top.

The third pipe 330 has a plurality of ventilation holes 331 communicating with the inside of the primary pipe 310 is formed.

In addition, the tertiary pipe 330 has a diameter smaller than that of the tertiary pipe 330 and is disposed inside the tertiary pipe 330 and the fourth pipe 340 communicating with the vent hole 331 is installed.

The fourth pipe 340 is formed in the same shape as the secondary pipe 320, but has a smaller diameter than the secondary pipe 320. Due to the fourth pipe 340, the rainwater falling into the ground through the through hole 311 is prevented from entering the third pipe 330.

Due to the tertiary pipe 330, the air can be supplied at any time when air is required in the primary pipe 310 to prevent the expansion and vacuum that may occur as the water flows down through the primary pipe 310.

The artificial cultivation drain 300a installed at the first end 140a and the second end 140b is provided shorter than the artificial cultivation drain 300b installed at the third end 140c to artificially cultivate water to the absorbent layer.

And it can be usefully used to secure water resources.

The role of the sand collecting unit 210 in the case of using the main filtering 100 and the cultivation capacity of the artificial cultivation drainage unit (300a, 300b) of the main filtering unit through the delivery pipe 137 connected to the second filter 130 Muddy water, gravel, sand, foreign matters as much as adjusted in consideration of the cultivation capacity of the artificial cultivation drainage portion (300c, 300d) of the sand collecting unit filtering portion.

The location of the sand catching unit 210 is a river area where the vehicle can be easily accessed to facilitate geological surveys or studies of minerals such as minerals upstream of the stream contained in the sand or to collect sand deposited thereon. It can be installed anywhere freely.

The sand collecting part 210 includes a bottom and sidewalls surrounding the bottom, so that a large space in which sand can be deposited is formed.

Furthermore, the slope 212 is installed at one side of the sand collecting unit 210 so as to smoothly enter the vehicle.

The partition 211 is provided at one edge of the sand collecting part 210.

The partition 211 is formed with an inlet 213 through which water from the sand collecting part 210 is introduced, and rainwater flows into the upper portion of the sand collecting part 210. Therefore, foreign matters such as sand or gravel are deposited in the sand collecting part 210 and pass only through the partition wall 211 including water containing only floating matters.

The partition collecting part 220 is disposed to be spaced apart from the partition 211 in the partition 211.

The partition collecting part 220 is introduced with water through the inlet 221 at the bottom to filter sand or gravel once again.

The partition collecting part 220 may be omitted as necessary.

Filtering unit 230 is a muddy water containing a float floating in the water passing through the sand collecting unit 210 to the top, and filters the introduced float.

That is, the filtering unit 230 is the inlet 231 is disposed in the upper portion, the water passing through the partition wall collector 220 is introduced.

In the filtering unit 230, a first space portion 230a, a second space portion 230b, a third space portion 230c, and a fourth space portion 230d are disposed along the water flow direction.

The filtering unit 230 includes a first filter 240 and a second filter 250 disposed below.

The first filter 240 is disposed above the first space portion 230a, the second space portion 230b, and the third space portion 230c.

The second filter 250 is installed above the first space portion 230a.

That is, the water introduced into the first space portion 230a through the first filter 240 is artificially cultured through the artificial cultivation drainage part 300c through the second filter 250 and the first filter 240. Water introduced into the third space portion 230c is artificially cultured through the artificial culture drainage part 300d.

Since the functions of the first filter 240 and the second filter 250 are provided in the same manner as the first filter 141 and the second filter 143 of the secondary filtering unit 140, description thereof will be omitted. .

The fourth space part 230d is a place where foreign matters filtered through the first filter 240 collect.

A foreign matter outlet 202 is formed in the fourth space portion 230d, and some muddy water and an outlet pipe 203 are connected to discharge the substance into the river. As a result, the collected foreign matter may automatically flow out into the stream through the outflow pipe 203.

The second space part 230b is a place where foreign matters including garbage collected through the second filter 250 disposed on the first space part 230a are collected.

In addition, a foreign matter discharge port 201 is also formed in the second space portion 230b to be connected to the stream and is connected to the outlet pipe 203.

Therefore, the water overflowing the foreign matter collected in the system will be discharged downstream of the stream.

A water discharge port 204 is formed in the second space portion 230b to communicate with the third space portion 230c, so that the second filter 250 is clogged with foreign matter, or into the ground through the artificial culture drainage portion 300c. When there is more water flowing from the inlet 231 than the water to be absorbed, the overflowed water is collected into the third space portion 230c through the water outlet 204 and then artificially flows into the aquifer with the groundwater through the artificial culture drainage 300d. It is cultivated.

The artificial cultivation drainage part 300c installed in the first space part 230a is provided shorter than the artificial cultivation drain part 300d installed in the third space part 230c and indirectly injects water to artificially cultivate the water to the absorbent layer.
