Description

Eco-friendly Rainwater Management System

The present invention relates to an environmentally friendly rainwater management system, and more specifically, to collect and purify rainwater during rainfall, while supplying purified water to a required location and place, and controlling the discharge rate with temporary storage. It relates to an environmentally friendly rainwater management system that enables a function.

In general, there is a decrease in groundwater due to factors such as continuous urban development, climate change, and environmental change, and also problems such as ecosystem damage and groundwater loss due to excessive inflow of contaminated rainwater.

This is because the pavement block or concrete pavement of the existing road does not absorb rainwater and the rainwater is washed away and lost.

As a result, it has become a cause of consolidation of urban rivers, etc., and thus, attempts to confine and utilize rainwater in places where water shortage is expected, such as in developed countries, have already been attempted.

The most commonly used rainwater storage configuration is to allow a certain amount of rainwater to be stored by forming a certain collection space in the basement.

Rainwater may be managed by operating a pumping station for the purpose of preventing flooding, and a reservoir or dam may be constructed to supply water to the dry season.

However, most pumping stations in the city are installed on the ground, so they are simply a means to prepare for excessive amounts of rainfall, and are usually left empty.

In some countries, in order to prevent the loss of rainwater, as described above, a separate catchment space is formed in the basement so that facilities to prevent rainwater evaporation are installed, but rainwater collected in the catchment space contains various pollutants. Since it is introduced, there is a difficulty in managing and cleaning regularly to remove such pollutants and to manage the collection space.

In the registered patent No. 14,5001 (road and sidewalk-type rainwater management system), the rainwater guide installed at the edge of the road and the rainwater induced through the water-permeable sidewalk block are tightened and filtered by a filter tank installed at the bottom of the facility, and then permeable. We have introduced a system that allows the storage tank to be stored in the sidewalk block so that the stored rainwater can be utilized through the rainwater utilization means.

In the prior art, such as a pre-registered patent, most of them simply store rainwater or use a separate filtering means before being stored to filter non-point pollutants contained in the initial stormwater.

Rainwater stored in this way is usually used for cleaning of roads or supplying water to roadside trees and landscape parks.

However, as described above, even if the conventional rainwater storage tank has been continuously stored for a certain period of time, it becomes secondary pollution as moss and the like are generated inside the storage tank and is filtered to filter rainwater flowing into the storage tank. There is a very troublesome and difficult problem in management of means and management of storage tanks.

In particular, the storage tank mainly formed in the basement is a large space is formed in the basement, so if it is damaged by an earthquake or a large number of constructions, it can cause very serious results.

1 is a schematic diagram illustrating an embodiment of an environmentally friendly rainwater management system according to the present invention.

As illustrated, the environment-friendly rainwater management system of the present invention is largely composed of a rainwater collection well 10 and a storage tank 20.

The rainwater storage technology composed of the rainwater collection tank 10 and the storage tank 20 is substantially the same as in the known technology, but the present invention improves the structure of rainwater purification and storage by the rainwater collection tank 10 and the storage tank 20. There are features to make it possible.

That is, the rainwater collection well 10 of the present invention is configured to be excreted for drainage of rainwater in public facilities such as the edge of a road or a park.

As shown in FIG. 2, the rainwater collection well 10 is opened upwards to form a space for receiving rainwater of a certain size into the inside, and a drain pipe 11 having a certain diameter is formed at the bottom so that rainwater flowing into the inside can be discharged. It is a connected configuration.

The rainwater collecting well 10 is such that the upper part is usually covered by a cover 12 such as grating, but in the present invention, the wire screen 13 having a network structure at a denser spacing at the lower part of the cover 12 This is provided so that relatively large trash or stones such as fallen leaves do not flow into the interior.

In the rainwater collecting well 10 of the present invention, a drain hole 101 may be formed with a diameter smaller than the diameter of the drain pipe 11 as shown in FIG. 2 on one side to which the drain pipe 11 is connected. As shown in the figure, while the drain hole formed with the same diameter as the existing drain pipe 11 is provided with a smaller diameter exclusion pipe 14, the inner end portion of the exclusion pipe 14 side of the rainwater collection crystal 10 is provided with a rainwater collection correction ( It is more preferable to bend downward toward the bottom of 10).

However, since the drain hole of one side to which the drain pipe 11 of the rainwater collection well 10 is connected is usually formed to have the same diameter as the inner diameter of the drain pipe 11, the inner diameter of the drain hole and the outer diameter of the exclusion pipe 14 are A diameter difference is generated, and the gap generated by the diameter difference is shielded by a stopper 15 provided to be detachable.

In this way, the non-point contaminants accumulated on the bottom surface of the rainwater collection well 10 by the exclusion pipe 14 connected to the drain pipe 11 are naturally discharged when the initial well is discharged.

That is, the rainwater passing through the drain hole 101 or the exclusion pipe 14 formed with a smaller diameter than the drain pipe 11 forms a faster flow rate due to the hydraulic pressure of the rainwater flowing into the drain pipe 11, so that the rainwater collector Non-point contaminants accumulated on the bottom layer of the crystal 10 can be easily discharged.

In addition, the rainwater collecting well (10) of the present invention is connected to the water collecting pipe (16) on one side at an upper portion of a certain height, and when the rainwater filled in the inside of the rainwater collecting water (10) exceeds a certain quantity, the water collecting pipe ( 16).

Therefore, by the rainwater collecting well 10 of the present invention, the initial rainwater is discharged through the drain pipe 11, and the rainwater having a low degree of contamination can be discharged through the collecting pipe 16 to store more clean rainwater. There are features to make it possible.

The rainwater collection well 10 is provided with a very large number in public facilities such as a road or a park, and may be collected from all of the rainwater collection wells 10, and only through some rainwater collection works 10 You can make it count.

And the storage tank 20 of the present invention is a rainwater collecting space provided in the basement such as a road or a park.

The storage tank 20 is a large-scale collection space installed underground as shown in FIG. 4, and the waterproof outer wall is provided to prevent the inflow of soil from the outside while preventing the water filled therein from being lost to the outside. The outer wall may be made of a concrete wall or may be made of metal, but it is more preferable to be made of concrete without fear of corrosion.

The inside of the storage tank 20 is empty inside at regular intervals, and the side of the water storage block 21 forming a plurality of water passages 210 is provided vertically, and the water quality between the water storage blocks 21 is provided. It is configured to be filled with purified stone (22).

At this time, the water storage block 21 may be formed in a single configuration, or may be formed in a configuration in which a plurality of configurations are stacked, and it is most preferable to be formed of a concrete block.

In addition, natural water zeolite, pulverized stone, and crushed stone are used as the water purification fossil 22 filled between the water storage blocks 21, shells and corals are used as natural materials, and ocher and artificial materials are used. It is desirable to mix clay and ceramic and charcoal with artificial basalt or to selectively mix them.

The upper surface of the storage tank 20 is connected to each of the rainwater collection wells 10 to be connected to the water collection pipes 16 so that rainwater from the rainwater collection wells 10 flows, and the pump 23 and the water supply pipe 24 ) To supply water to the outside.

However, the storage tank 20 may be provided with an inspection room 25 that allows the administrator to enter and exit from the outside for maintenance of various valves together with the pump 23.

On the other hand, the upper portion of the storage tank 20 is discharged from the storage tank 20, the discharge pipe 26 to discharge the rainwater that overflows is buried in the ground so that it is absorbed into the ground above the limit quantity.

5 is a schematic diagram illustrating another embodiment of an environmentally friendly rainwater management system according to the present invention.

As illustrated, the environment-friendly rainwater management system according to another embodiment of the present invention has the same structure as the rainwater collection tank 10 and the reservoir 20.

However, this embodiment is characterized in that the planter block 30 is connected between the rainwater collection well 10 and the storage tank 20.

The planter block 30 in this embodiment is a housing that allows the inside to be opened to the top of the remarks, and is made of a concrete block that allows a plurality of vegetation holes 31 to be formed on the side surfaces, and a certain height at the bottom inside. The water purification fossil 32 is loaded, and the vegetation soil 33 is filled at a height reaching the upper portion at the top, and the tree 34 is planted at the top of the vegetation soil 33.

At this time, while the vegetation hole 31 is formed at various heights, at least the vegetation hole 31 at the lower end is formed at a height lower than the height of the top portion of the water purification fossil 32, and such a planter block 30 has only the upper portion. Be buried in the ground for upward exposure from the ground.

In addition, the water purification fossil 32 loaded inside the planter block 30 is applied in the same manner as the water purification fossil 22 filled in the storage tank 20.

On the other hand, the planter block 30 of this embodiment is to be buried in the ground at least up to the height of the water purification fossil 32, as shown in Figure 6, so that the trees are planted in the vegetation hole 31 on the side exposed to the top of the ground Formation is also possible with the configuration.

Between the rainwater collection well 10 and the storage tank 20, the planter block 30 is connected to the rainwater collection well 10 by a first water collection pipe 17, as shown in FIG. 7, and the storage tank 20 And to be connected by the second collecting pipe 35.

In other words, in the above-described embodiment, the planter block while dividing the collection pipe 16 connected between the rainwater collection rig 10 and the storage tank 20 into the first collection pipe 17 and the second collection pipe 35 Each end is connected to a different vegetation hole 31 buried in the ground at 30.

However, the vegetation hole 31 to which the ends of the first water collecting pipe 17 are connected and the vegetation hole 31 to which the ends of the second water collecting pipe 35 are connected are connected to vegetation holes 31 having different positions, respectively. By doing so, the primary water purification is performed while the rainwater flowing through the first water collecting pipe 17 passes through the water purification fossil 32 and then supplied to the storage tank 20 through the second water collecting pipe 35.

The operation method using the eco-friendly rainwater management system of the present invention according to the above configuration will be described in more detail as follows.

As shown in FIG. 8, once the rain falls, the rain flows into the rainwater collection plant 10 installed at the edge of a road or a pedestrian path such as a park.

In the rainwater collection plant 10, relatively large-sized garbage such as fallen leaves is filtered by the cover 12 and the wire screen 13 made of grating at the upper end, and non-point contaminants such as relatively small foreign substances are collected along with the rainwater. Inflow.

Rainwater flowing into the rainwater collection well 10 is discharged through the drain pipe 11 together with non-point contaminants accumulated on the floor, and at this time, the drain hole 101 or the exclusion pipe 14 having a smaller diameter toward the drain pipe 11 side ) Is provided, and the initial good is discharged to the drain pipe 11 through the drain hole 101 or the exclusion pipe 14.

However, when the flow rate of rainwater flowing into the rainwater collection well 10 becomes higher than the flow rate discharged through the exclusion pipe 15, the water level gradually increases inside the rainwater collection well 10, and the water pressure increases as the water level increases. Since it becomes stronger, non-point contaminants from the bottom of the rainwater collection well 10 are discharged to the drainage hole 14 at a faster rate through the exclusion pipe 15.

When the rainwater separated from the non-point pollutants becomes higher than the formation height of the collecting pipe 16 or the first collecting pipe 17 of the rainwater collecting well 10, the rainwater collects together with the drainage pipe 11 below. It is also discharged through (16) or the first collection pipe (17).

Rainwater flowing through the collecting pipe 16 or the first collecting pipe 17 may be directly supplied to the storage tank 20 or may be supplied to the storage tank 20 via the planter block 30.

Rainwater passing through the planter block 30 passes through the water purification fossil 32 loaded in the lower part of the planter block 30 as shown in FIG. 7, and after the primary purification is performed, the second water collecting pipe 35 It can be leaked through and can be supplied to the storage tank 20.

The rainwater that has been first purified through the planter block 30 is supplied to the storage tank 20 to be purified again.

That is, as shown in FIG. 9, rainwater supplied to the storage tank 20 through the water collection pipe 16 or the second water collection pipe 35 directly from the rainwater collection well 10 or via the planter block 30 is stored in the storage tank. It is gradually filled from the bottom in the interior of (20).

When a certain amount of rainwater is already filled in the storage tank 20, the remaining water level is filled, and rainwater flowing into the storage tank 20 or more is discharged to the outside through the discharge pipe 26 to be absorbed in the ground. .

The rainwater filled in the storage tank 20 is filled in the empty storage block 21 through the water hole 210 formed on the side surface of the storage block 21, and the water storage blocks 21 It is also filled in between the water purification fossils 22 made to be filled in between.

Rainwater that is filled in the storage tank 20 is continuously purified by the water purification fossil 22, and the purified rainwater forms water quality of a medium water level that cannot be used only as drinking water, so it is discharged to the outside. It can be used for various purposes.

When the water filled in the storage tank 20 is used, the water filled in the water storage block 21 also comes out of the water storage block 21 through the through holes 210 again. Purification can be done.

The water that is filled and purified in the storage tank 20 may be sprayed on the road in a dry environment such as a dry season to prevent heat island phenomenon, or may be sprayed in a mist to prevent scattering of fine dust.

In addition, it can be used not only for garden trees such as street trees or parks, but also for medium water quality, so it can be supplied as a variety of water, not drinking water, such as public toilets.

In this way, the present invention is to be excluded with respect to the initial good, while continuously purifying the rainwater collected in the storage tank 20 by the water purification fossils 22, 32 to form a medium-grade water to be used for more various uses In addition to this, it also helps to control flooding in the city and efficiently use unnecessarily wasted rainwater.

In addition, the primary purification is performed by the water purification fossil 32 of the planter block 30 while the non-point contaminants are removed by the initial excellent according to the present invention, and at the same time the water storage tank 20 is filled with water quality. Since purification can be continuously performed by the purification stone 22, it is possible to supply more clean water, thereby increasing the range of use for more various uses.

Particularly, the present invention can keep the inside of the storage tank 20 clean by the continuous purification action in the storage tank 20, and thus does not require management such as separate cleaning, and when using purified water Only the pump 23 can be operated manually or remotely so that purified water can be supplied to the required location and place, and management is possible through the inspection room 25 that can be easily accessed by the administrator. It has the advantage of being very convenient to manage.

As described above, the present invention is not limited to the described embodiments, and it can be obvious to those skilled in the art that various modifications and modifications can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to belong to the claims of the present invention.
