Description

Non-point polluted rainwater separation and purification device and its construction method {system separating and purifying rainwater polluted by non point and construction method using the system}

The present invention relates to a device configured to separately separate and purify non-point polluted rainwater on the road caused by rainwater coming from the beginning and use it as underground infiltration water, and a purification method using the device. Details are provided to a device installed at the boundary between a roadway and a sidewalk. A boundary stone for separating rainwater (hereinafter referred to as a boundary stone for separating rainwater) is aligned with the boundary stone and arranged at an interval adjusted according to the width of the roadway, and the boundary stone is formed so that rainwater from the roadway can be discharged under the rainwater separation boundary stone. The upper part is formed to protrude in an arch-like shape, and the bottom part also forms a space between the round-shaped roadway and the boundary stone, and a two-stage drain pipe is connected to the space. Non-point polluted rainwater, which is the first rainwater on the roadway, is drained into the first stage drain pipe. It is discharged and stored in an underground storage tank, purified, and is configured to infiltrate into the ground. It is configured to discharge into the first-stage drain pipe and the second-stage drain pipe, where the incoming rainwater is more than the rainwater that penetrates into the ground from the purification tank, and the connecting pipe of the first-stage drain pipe A damper is formed in the purification tank to prevent the rainwater flowing into the purification tank from flowing back, so that non-point polluted rainwater cannot be discharged into the underground storm drain under any circumstances, so that the purified rainwater penetrates into the ground to form clean groundwater and clean rainwater. It relates to a non-point polluted rainwater separation and purification device configured to discharge into a river and a method of constructing the same.

The technology for treating the first contaminated rainwater is exemplified in Patent No. 10-1252242 (Initial rainwater treatment type rainwater gutter, hereinafter referred to as conventional technology).

The above conventional technology is characterized by being installed at the lower part of a grating installed on the ground of a road, and is composed of a collection box that receives rainwater flowing into the grating and a drainage box that accommodates the collection box, and the rainwater that flows into the collection box is filtered. It is configured to pass through the box and permeate into the ground, and rainwater that does not penetrate into the ground is configured to move to the storm drain. If there is a lot of rainwater flowing in, it is not able to pass through the filter box and moves from the collection box to the drainage box and then moves to the storm drain. You can see that it exists.

As mentioned above, the rainwater that flows in from the initial rainwater accumulates foreign substances, including trash, in the collection box, so if there is little rain, all of the rainwater can be filtered, but if there is a lot of rainwater flowing in, it moves directly from the collection box to the rainwater pipe, so it flows into the collection box. As accumulated foreign substances and trash move into the storm drain, unpurified rainwater moves into the river, which can purify underground percolation water, but has the problem of not improving river water quality. Rainwater also flows into the grating, so non-point polluted rainwater. There is a problem that water and rainwater cannot be separated.

The purpose of the present invention is to keep ground seepage water and rainwater discharged into rivers clean through a device for separating, storing, and purifying non-point polluted rainwater, which is the first rainwater, and a method of separating and purifying rainwater using the device.

The purpose of the present invention is to configure it so that it can be applied to newly built and renovated roads, and the purpose is to maintain clean groundwater with clean rainwater, prevent depletion of groundwater, and restore clean rivers.

In order to solve the present invention, rainwater is discharged through a drain pipe integrated with the boundary stone, and the rainwater is stored in an underground rainwater purification tank to purify and discharge the initial non-point polluted rainwater on the roadway.

The boundary stone according to the present invention can be formed by molding it with waste vinyl or synthetic resin integrally with the drain pipe.

The present invention includes a process of forming a boundary stone for drainage, a process of forming a drain pipe consisting of 1 and 2 stages, a process of arranging boundary stones at the border of a sidewalk in connection with a roadway, and distributing boundary stones at predetermined intervals in the arrangement of the boundary stones. A process of arranging a receiving boundary stone, a process of arranging a drain pipe protector connected to a drain pipe in connection with the boundary stone and the roadway, a process of coupling a drain pipe to the guard, and combining the first stage drain pipe of the drain pipe and the first connection pipe. A process of preventing backflow of rainwater in the first connection pipe, a process of connecting the first connection pipe to a purification tank, and rainwater flowing into the first-stage drain pipe through the openings of the first-stage drain pipe and the second-stage drain pipe. It consists of a process of passing through and discharging into a second-stage drain pipe and a second connection pipe, and a process where the second-stage drain pipe is connected to a rainwater pipe and clean rainwater moves to the rainwater pipe.

In the present invention, boundary stones for drainage are arranged at predetermined intervals in an array of boundary stones arranged in connection with a roadway, and the boundary stones are formed in an arch shape, and the arch shape is configured to form an arch-shaped space between the boundary stones and the ground.

It is configured to fix a guard to support the drain pipe between the drainage boundary stone and the ground, and the guard forms a grill to prevent foreign substances from entering.

The drain pipe has an inlet of 1 and 2 stages, and is configured to allow the initial rainwater, non-polluted rainwater, to flow into the 1st stage drain pipe. As the amount of rain water increases, the 2nd stage drain pipe flows in the overflowing rainwater and becomes a rainwater pipe. It is configured so that it can be transferred to .

As the amount of rainwater flowing into the first-stage drain pipe increases, the rainwater in the purification tank containing the rainwater is prevented from flowing back, and foreign substances in the purification tank are prevented from being discharged into the second-stage drain pipe.

Rainwater flowing into the first stage water pipe was configured to be accommodated in a purification tank.

A check valve type damper was installed on the connection pipe of the first stage drain pipe so that rainwater from the drain pipe could be received in one direction into the purification tank.

The purification tank is configured to accommodate a bag, and the bag is configured to collect and filter foreign substances, so that foreign substances in rainwater can settle in the bag, and the rainwater filtered in the bag is configured to penetrate into the ground.

Several drain holes were drilled on five sides of the purification tank to allow rainwater to drain.

A conical protrusion is formed on the inner wall of the purification tank to prevent the bag accommodated in the purification tank from coming into close contact with the inner wall of the purification tank, and a drain hole is formed from the inner wall to the outer wall to discharge rainwater filtered from the bag of the purification tank. When the bag is full of foreign matter, the protrusions form a space between the inner wall of the purification tank and the bag so that rainwater filtered from the upper part of the bag can easily be discharged into the ground through various drainage holes through the space. When it is full, the bag is configured to be replaced by a sensor.

The drain hole formed on the wall of the purification tank is drilled from the inside of the wall to the outside, and a cone-shaped protrusion is formed at the entrance of the drain hole exposed on the outer wall to facilitate underground penetration and to ensure that the purification tank is firmly supported in the ground.

Protrusions are formed on the inner wall of the purification tank so that the bag is spaced apart from the inner wall so that rainwater filtered anywhere in the bag can easily be discharged through the entire drainage hole. When the bag is separated, it is configured so that it can be easily separated from the purification tank. did.

A lid was formed on the top of the purification tank so that it could be opened, and the bag could be separated and exchanged.

When the bag of the purification tank overflows with foreign matter to the extent that rainwater cannot be purified, a sensor mounted on the top of the purification tank operates to replace the bag to prevent non-point polluted rainwater from continuously flowing into the ground and rivers. did.

The present invention omits the separate work of the grating hole during road work and allows the work to be performed simultaneously by connecting the drain pipe, which is integral with or formed integrally with the boundary stone, to the rainwater purification tank and the rainwater pipe when working on the boundary stone, so that the work can be performed quickly. It has the effect of low operating costs.

The present invention installs a two-stage drain pipe in the drainage formed on the road. Since the first rainwater contains contaminants from the roadway, the first rainwater is drained into the first stage of the drain pipe and stored in a separate purification tank. Clean groundwater can be created by discharging the purified rainwater into the ground, and the backflow of rainwater that flows back into the purification tank due to the large amount flowing into the purification tank is blocked by the damper of the first connection pipe, so in any case, non-point pollution rainwater in the purification tank is blocked. By preventing this backflow, rainwater flowing into the purification tank does not pollute groundwater, and rainwater discharged into storm drains does not pollute the river.

The present invention relates to a device for purifying groundwater by separately draining and purifying non-point polluted rainwater and discharging it into the ground, and a method using the device.

The present invention forms drain pipes (11a, 11b) in connection with the boundary stones 103 of the roadway 100 and the sidewalk 101, and is formed to drain rainwater from the roadway 100, and is formed to drain rainwater from the roadway 100 and the roadway 00 by the first rainwater. Non-point polluted rainwater mixed with contaminants is purified by flowing into the purification tank 12 through the first stage drain pipe (11a) of the first and second stage drain pipes (11a, 11b), and the purified non-point polluted rainwater penetrates into the ground. Constructed to do so, the rainwater that continues is drained into the second connection pipe (13b) through the first and second stage drain pipes (11a, 11b) and discharged into the rainwater pipe (23), so that non-point polluted rainwater is not purified under any circumstances. It relates to a device that does not penetrate into the ground and is configured so that non-point polluted rainwater cannot be discharged into the rainwater pipe (23) under any circumstances.

As shown in Figure 2, boundary stones 103 are arranged continuously at the boundary between the roadway 100 and the sidewalk 101, and boundary stones 15 for drainage are arranged at any point of the boundary stones 103.

The drainage boundary stone 15 is formed to be rounded in an arch shape across the top and bottom to form a space between the ground and the boundary stone 15 to form a drain 16 for rainwater.

A guard 17 is formed in the sewer 16 across the boundary stone 15 and the roadway 100, and the guard 17 is configured to firmly support the boundary stone 15 and the roadway 100.

The guard 17 is formed in a grill shape to filter out foreign substances 104, and is configured to be located under the sidewalk 101 by inserting the drain pipes 11a and 11b from the direction of the roadway 100 to the direction of the sidewalk 101. It is done.

The drain pipes 11a and 11b are formed in two stages as shown in FIG. 2, and each drain pipe 11a and 11b is composed of connection pipes 13a and 13b.

The first-stage drain pipe (11a) has an opening 19 formed between the second-stage drain pipes (11b), so that when the amount of rainwater moving to the first-stage drain pipe (11a) increases, the rainwater discharged to the first-stage drain pipe (11a) increases. It is configured to discharge through a two-stage drain pipe (11b).

The first-stage drain pipe 11a is configured to separate and drain non-point polluted rainwater, which initially comes to the roadway 100 and contains contaminants of the roadway 100, and receive it in the purification tank 12.

As shown in FIG. 2, the purification tank 12 is configured to have a first connection pipe 13a coupled to its side, and inside the purification tank 12 is a bag 14 made of a material capable of collecting foreign substances 102. ) is accommodated and is configured to allow rainwater from the first connection pipe (13a) to flow into the bag (14).

As shown in FIG. 2, the purification tank 12 has drainage holes 18a formed on the side and bottom, so that the rainwater filtered out of the non-point polluting rainwater 102 of the bag 14 is discharged into the ground. It is designed to be penetrable.

The plurality of drainage holes 18a formed on the inner and outer walls of the purification tank 12 form conical protrusions 24 on the outer wall to facilitate the discharge of rainwater and to firmly support the purification tank.

A plurality of protrusions (18b) are formed on the inner wall of the purification tank to form a space by forming a gap between the inner wall and the bag (14), and even when the bag (14) is full of foreign substances, it is easy to filter rainwater through the upper part of the bag (14). It is easy for rainwater to penetrate the ground into the drainage hole (18b) through the space between the bag (14) accommodated in the purification tank (12) and the inner wall of the purification tank (12), and the bag (14) can be easily discharged from the inner wall. The bag 14 is configured to be easily separated from the purification tank 12 in a spaced apart state.

A check valve-type damper 21 is formed in the first connection pipe 13a to facilitate the inflow of rainwater into the purification tank 12, but to prevent backflow of rainwater from the purification tank 12.

As described above, the first rainwater in the driveway 100 flows into the first-stage drain pipe 11a, passes through the check valve-type damper 21 through the first connection pipe 13a, is received in the purification tank 12, and continues to flow. When rainwater after non-point pollution rainwater increases due to the coming rain and the rainwater fills the purification tank (12) drained through the first stage drain pipe (11a), the rainwater in the purification tank (12) flows back by the check valve type damper (21). Since this cannot be done and the purification tank (12) is filled with rainwater, the rainwater in the first stage drain pipe (11a) moves to the second stage drain pipe (11b) through the opening part (19) and is mixed with the rainwater in the first stage drain pipe (11a) and the second stage drain pipe (11a). Rainwater in the drain pipe 11b is configured to move to the rainwater pipe 23 through the second connection pipe 13b and be discharged into the river.

As exemplified in Conventional Technology No. 10-1252242 of the present invention (early rainwater treatment type rainwater gutter, hereinafter referred to as conventional technology), through a sewage hole installed at the bottom of the grating installed on the ground of the road. Rainwater discharged into storm drains does not separate the non-point polluted rainwater, which is the first rainwater on the roadway, and discharges all of it into the river. Therefore, there are problems with rivers being polluted, rivers being polluted, and the sea being polluted, and groundwater being depleted, leading to a water shortage. This is to address the phenomenon that occurs.

In the present invention, the drainage boundary stone 15 can be made of the same material as the general boundary stone 103, and can be molded from waste vinyl and waste synthetic resin in various colors to be visually distinguished.

The drain pipes (11a, 11b) according to the present invention are composed of a first and second stage, but are integrated, and the partition wall between the first and second stage drain pipes (11a, 11b) is completely open or formed in a grill shape to form the first stage drain pipe (11a). Rainwater can be discharged to the second-stage drain pipe (11b), but the discharge of foreign substances 104 in the first-stage drain pipe (11a) is configured through the forming process of the drain pipe (11a, 11b), and the drain pipe At the rear of (11a, 11b), the connecting pipes (13a, 13b) can be formed as one piece, and the connecting pipes (13a, 13b) are formed separately and can be used by combining them with the drain pipes (11a, 11b).

The rear part of the first connection pipe 13a can be connected by adjusting the size of the first connection pipe 13a according to the position of the purification tank 12.

The process of arranging the boundary stones 15 for drainage generally involves placing the boundary stones 15 for drainage at a predetermined interval between the boundary stones 103 placed on the border of the roadway 100 and the sidewalk 101.

The drainage boundary stones 15 can be densely spaced depending on the width of the roadway 100, and the spacing can be adjusted depending on where there is a lot of rainwater.

Since the drainage boundary stone 15 forms a space between the roadway 100 and the sidewalk 101, it is formed in an arch shape, but is placed exposed higher than the general boundary stone 103, and its bottom also forms an arch and the roadway (100) ) and a space are formed, and drain pipes (11a, 11b) are installed in the space.

The guard 17 can be fixed between the roadway 100 and the curb 15 so that the drain pipes 11a and 11b can be firmly fixed to the curb 15 for drainage.

In addition, in another method, the guard 17 can be molded integrally with the drain pipes 11a and 11b and fixed to the boundary stone 15 and the roadway 100.

The first rainwater moves to the first-stage drain pipe (11a) and is configured to be accommodated in the purification tank (12). However, in reality, the initial amount of rainwater may vary depending on the amount of rainwater that initially pours, but rainwater does not flow into the driveway (100). It is assumed that the initial rainwater in the driveway (100) is discharged into the first-stage drain pipe (11a) at the level of flow, and thereafter, clean rainwater in the driveway (100) also flows into the first-stage drain pipe (11a) and is accepted into the purification tank (12). do.

When more rainwater flows into the purification tank (12) than rainwater penetrating into the ground, the rainwater in the purification tank (12) flows back and the foreign substances (104) remaining in the purification tank (12) also flow back into the two-stage drain pipe (11b). Since it is discharged to , there is a problem that the rainwater pipe 23 is polluted.

In the present invention, even when rainwater overflows in the purification tank 12, a check valve type damper 21 is mounted on the first connection pipe 13a to prevent the rainwater in the purification tank 12 from flowing back, so that the first stage drain pipe ( It is easy for rainwater in 11a) to flow into the purification tank (12), but the rainwater in the purification tank (12) is prevented from flowing back, and the rainwater in the first stage drain pipe (11a) is no longer discharged to the purification tank (12). However, it is discharged through the drain pipe (11b).

In the check valve type damper 21 as described above, when the rainwater in the purification tank 12 is reduced by underground infiltration, the rainwater in the first stage drain pipe 11a continues to flow into the purification tank 12, and the amount of rainwater that continues is Even when the amount decreases, rainwater continues to be discharged only through the first stage drain pipe (11a), flows into the purification tank (12), and penetrates into the ground from the purification tank (12), and the infiltrated rainwater constitutes groundwater.

As described above, the present invention is intended to purify the initial non-point contaminated rainwater of the driveway 100 to form groundwater, and a small amount of rainwater also forms groundwater.

The present invention can be installed on newly built roads to avoid duplication of construction, but water shortages occur due to climate change, and especially in areas where the rainy season and dry season are divided and the rainy season is concentrated in one season, water overflows at some times and at other times. As water shortage becomes more pronounced and civilization develops, the surface pavement rate increases and the amount of rainwater infiltrates into the ground decreases. Therefore, there is a problem of depletion of groundwater even when it rains, so only the boundary stone (15) is replaced on the existing road (101). It is possible to prevent depletion of groundwater by easily applying the present invention only by means of burying the purification tank 12 and the means of burying the purification tank 12.

An embodiment of the present invention is implemented by applying it to a new road.

Once the height of the roadway 100 and the slope of both edges are determined, the boundary stone 15 may be placed between the roadway 100 and the sidewalk 110, and the boundary stone 15 may be placed after the roadway 100 is paved. In some cases, it is placed.

The drainage boundary stone 15 according to the present invention can be placed in any case, and it is desirable to install a guard 17 to secure the drain pipes 11a and 11b when arranging the drainage boundary stone 15.

This is because after installing the protector 17, the drain pipes 11a and 11b can be coupled and fixed to the protector 17 at any time.

When the boundary stone 15 is placed and the guard 17 is installed as described above, the two-stage drain pipes 11a and 11b are coupled and fixed to the guard 17.

It is preferable that the depth of the purification tank 12 installed on the sidewalk 102 is installed at a depth that can prevent the ground from sinking, taking into account the amount of water infiltrating the ground in the purification tank 12.

After fixing the drain pipes (11a, 11b) to the guard (17) installed on the drainage boundary stone (15) as described above, the first and second connection pipes (13a, 13b) are connected to the first and second stage drain pipes (1a, 11b). become combined.

The first connector (13a) of the first stage is connected to the purification tank (12), and the second connector (13b) of the second stage is connected to the rainwater pipe (23).

When it rains, the rainwater on the roadway 100 is mixed with various contaminants generated on the roadway 100 (tire powder, asphalt powder, dust, etc. generated from friction with the road) and moves to the drain pipes 11a and 11b, and is the first rainwater. Since the amount is small, it moves to the first stage drain pipe (11a), passes through the first connection pipe (13a), and is received in the purification tank (12).

Since the bag 14, which is easy to filter, is water-soluble inside the purification tank 12, rainwater is stored inside the bag 14.

Rainwater flowing into the bag 14 of the purification tank 12 is filtered and discharged as clean rainwater.

The discharged rainwater is discharged through the drainage hole (18a) formed in the purification tank (12) and penetrates into the ground.

The protrusion 24 of the drain hole 18a formed on the outer wall of the purification tank 12 facilitates the discharge of rainwater into the ground and is firmly supported in the ground.

The protrusion 18b protruding from the inner wall of the purification tank 12 is configured to separate the bag 14 from the inner wall of the purification tank 12, so that rainwater can be easily discharged from the spaced space.

As described above, if the inner wall of the purification tank (12) and the bag (14) are spaced apart, the bag (14) is full of foreign matter (102) and rainwater filtered only in the upper part of the bag (14) flows into the bag (14) and the purification tank (12). ) It is easy to freely discharge rainwater from the space formed on the inner wall of the drain hole (18a).

As described above, when the amount of rainwater flowing into the first-stage drain pipe (11a) increases, the rainwater from the first-stage drain pipe (11a) is discharged to the second-stage drain pipe (11b) through the first-stage and second-stage drain pipes.

As described above, when the rainwater flowing into the first stage drain pipe (11a) fills the purification tank (12), the rainwater in the purification tank (12) flows back, and when it flows back, the foreign matter (102) in the bag (14) also flows back. Therefore, in order to prevent backflow of rainwater from moving to the second-stage drain pipe (11b), the check valve type damper 21 formed on the first connection pipe (13a) blocks backflow from the purification tank (12).

When the purification tank 12 is filled with rainwater, the rainwater in the first-stage drain pipe 11a moves to the second-stage drain pipe 11b through the opening 19 and is discharged into the rainwater pipe 23.

As described above, when it rains so much that rainwater fills the purification tank (12), the non-point pollution rainwater on the roadway (100) is contained in the purification tank (12), so that it flows into the first-stage drain pipe (11a) and the second-stage drain pipe (11b). Since rainwater becomes clean rainwater, rainwater discharged through the rainwater pipe 23 does not pollute the river with clean rainwater.

When the bag 14 of the purification tank 12 is filled with foreign substances 104, the bag 14 is attached to the inner wall of the purification tank 12 and is not easy to separate, so it is attached to the wall of the purification tank 12. The formed protrusion (18b) makes it possible to form a gap between the purification tank (12) and the bag (14), so that the bag (14) can be easily separated from the purification tank (12), and the drain hole (18a) Since it is not in close contact with the bag (14), the rainwater filtered from the upper part of the bag (14) by the foreign substances (102) filled in the bag (14) moves to the space formed between the inner wall and the bag (14), allowing the rainwater to easily enter the ground. can be discharged.

As described above, when the bag 14 is filled with foreign substances 102 over a long period of time, the sensor 26 operates, the lid 25a on the ground and the lid 25b of the purification tank 12 are opened, and the bag 14 ) can be exchanged, preventing contaminated rainwater from being discharged into the ground under any circumstances.
