Description

Rainwater treatment system using vegetation and soil filtration

The present invention relates to a rainwater management system, and more specifically, to a rainwater management system using vegetation and soil filtration, which purifies collected rainwater using vegetation and soil filtration, allows the purified rainwater to infiltrate not only the lower part of the system but also the surrounding permeable ground to increase the infiltration amount of rainwater, and when the amount of rainwater increases, discharges it into a sewer to restore the water cycle through the purification and infiltration of rainwater and prevent flooding.

In general, as the impermeable surface area of a city increases due to paving, etc., sewerage facilities consisting of rainwater gutters and pipes for draining rainwater are installed.

However, these sewerage facilities have the problem that the amount of rainwater that infiltrates into the soil is extremely small, as they drain directly into rivers or the sea without any structure to allow rainwater to infiltrate into the soil.

In particular, during the rainy season in summer, when heavy rain is concentrated, rainwater cannot be fully stored in the rain gutters, forming puddles of water, making it impossible for people or vehicles to pass.

In addition, there is a problem that the sewer cover or sump cover may be damaged by the reverse flow of rainwater due to a sudden increase in drainage, or the cover may rise due to water pressure, causing secondary damage.

To overcome this, as disclosed in the previously registered utility model No. 20-0467111, a device is used that allows water to flow in and easily reverse when the discharge amount is large.

However, these devices are not a fundamental solution to drainage problems, are completely unrelated to drainage efficiency, and have the problem of reducing the function of allowing rainwater to infiltrate the soil.

Meanwhile, recently, green space has been created around roads to increase the amount of rainwater that seeps into the ground, thereby solving previous problems and providing a green environment.

However, since flooding still occurs if rainwater that falls on the road is not quickly drained, there is an urgent need to develop technology that can effectively store collected rainwater, quickly drain it from the road, and effectively infiltrate it into the soil to maintain the surrounding green environment.

Accordingly, the present invention has been made to solve the above-mentioned problems, and the purpose of the present invention is to provide a rainwater treatment system using vegetation and soil filtration, which comprises a rainwater inflow portion into which rainwater that has fallen on a road is collected, a filtration section for filtering the rainwater that has flowed in through the rainwater inflow portion, an infiltration section for infiltrating some of the rainwater filtered in the filtration section into the ground of surrounding green space, and a drainage section for draining some of the rainwater filtered in the filtration section into a rainwater pipe, thereby collecting rainwater that has fallen on a road, filtering it with plants, and then infiltrating it into the ground, thereby creating a vegetation environment around the road, as well as preventing and minimizing ground pollution, and preventing flooding by quickly draining it into a rainwater pipe when there is a lot of rainfall.

The present invention for achieving the above object comprises a rainwater inflow portion into which rainwater falling on a road is collected, a filtration unit for filtering the rainwater flowing in through the rainwater inflow portion, an infiltration unit for infiltrating some of the rainwater filtered in the filtration unit into the ground of a surrounding green space, and a drainage unit for draining some of the rainwater filtered in the filtration unit into a rainwater pipe.

Preferably, the rainwater inlet includes a rainwater inlet formed on a road curb, and an inlet slope formed to be inclined so that rainwater from the road flows into the rainwater inlet.

And the above first outlet is a trapezoidal shape in which the length of the lower side is longer than the length of the upper side, and the above second outlet is a trapezoidal shape in which the length of the upper side is longer than the length of the lower side.

In addition, the third outlet hole is a slit-shaped hole formed long in the left-right direction with the same width.

In addition, the third panel further includes a baffle to cover the front side of the third outflow hole in the direction of rainwater inflow, thereby preventing vegetation soil from flowing in together.

In addition, it further includes a flower bed infiltration section for allowing the excellent water of the above-mentioned filter space to infiltrate into the ground.

As shown in the drawing, the rainwater treatment system for roadside green space creation includes a rainwater inflow section (100), a filtration section (200), an infiltration section (300), and a drainage section (400).

The rainwater inflow section (100) is formed at regular intervals along the road to collect rainwater that falls on the road (1).

And the filter unit (200) is provided to filter the rainwater flowing in through the rainwater inflow unit (100).

The infiltration unit (300) is provided to infiltrate some of the rainwater filtered in the filtration unit (200) into the ground of the surrounding green space.

In addition, the drainage unit (400) is for draining some of the rainwater filtered in the filtration unit (200) into a rainwater pipe.

According to this rainwater treatment system for roadside green space creation, by collecting and draining rainwater that falls on the road, road flooding is prevented, and the collected rainwater is filtered through a filter bed (200) for a certain period of time and then infiltrates into the ground, thereby maintaining the moisture content of the surrounding ground.

In particular, since the collected rainwater is filtered by the filtration unit (200), even if it infiltrates the ground, contamination can be prevented and minimized.

Accordingly, it is possible to prevent road flooding, create green spaces around roads, and minimize pollution caused by rainwater.

For this purpose, the superior inflow portion (100) includes a superior inflow port (110) and an inflow slope portion (120), as illustrated in FIG. 2.

The rainwater inlet (110) is formed on the road (1) curbstone (2), and in some cases, may be formed on the road shoulder (2).

And the inlet slope (120) is formed to be inclined so that the rainwater from the road (1) flows into the rainwater inlet (110).

This inlet slope (120) corresponds to the shoulder of the road (1), and it is natural that it is formed with a slope in the circumferential direction centered on the rainwater inlet (110).

Here, the excellent inflow portion (100) further includes an inflow grating (130).

This inflow grating (130) is detachably installed on the rainwater inflow port (110) to filter out foreign substances contained in rainwater and prevent foreign substances from flowing in.

And, as shown in Fig. 3, the filtering unit (200) includes a flower bed body unit (210) and a filtering unit (220).

The flower bed body (210) has a filtering space (202) that is open upwards inside and is installed underground.

In addition, a filter (220) is provided in the filter space (202) of the flower bed body (210) to filter the flowing water.

This filter unit (220) includes a first filter unit (222) and a second filter unit (224).

The first filter unit (222) stores rainwater introduced through the rainwater inflow unit (100) and removes sediment.

And at least one second filter (224) is provided to filter the rainwater that has passed through the first filter (222) through the planted plants.

Here, the filtration space (202) includes a first filtration space (202a) equipped with a first filtration unit (222) and a second filtration space (202b) equipped with a second filtration unit (224).

These first filtering unit (222) and second filtering unit (224) are arranged in series, and are preferably formed along the road (1). In some cases, they may be formed perpendicular to the road (1) or at a certain angle.

For this purpose, the first filter unit (222) includes a first vegetation layer (2222) and a mulching layer (2224).

The first vegetation soil layer (2222) is formed on the lower surface of the first filter space (202a), and the mulching layer (2224) is laminated on the upper side of the first vegetation soil layer (2222) to prevent plants from growing on the first vegetation soil layer (2222).

And the second filter unit (224) includes a second vegetation layer (2242) for planting plants.

Here, the height of the second vegetation layer (2242) is formed to be the same as or different from the heights of the first vegetation layer (2222) and the mulching layer (2224).

Accordingly, the water levels of the first filtration space (202a) and the second filtration space (202b) are maintained the same.

And the flower bed body (210) includes a post (212), a panel (214), and a flower bed connection part (216), as shown in FIG. 4.

Posts (212) are installed in multiple places at the corners of the first filter section (222) and each second filter section (224).

In addition, multiple panels (214) are provided between adjacent posts (212) to partition each filter section (222, 224).

A flower bed connecting part (216) is provided to connect each panel (214) to the corresponding post.

And the panel (214) includes a first panel (2142), a second panel (2144), a third panel (2146), and a bottom panel (2148).

And the second panel (2144) is provided to partition the first filter section (222) and the second filter section (224).

The third panel (2146) is provided to partition each second filter section (224).

Additionally, a bottom panel (2148) is provided to form the bottom of the filter space (202).

Here, the first panel (2142) and the second panel (2144) are formed at the same height, and the first panel (2142) has a first outflow hole (2142a) formed at the lower portion to allow the rainwater flowing into the first filter (222) to permeate into the surrounding ground.

And the second panel (2144) has a second outlet (2144a) formed at the upper part so that the filtered water from the first filter (222) is supplied to the second filter (224).

The third panel (2146) is formed lower than the first panel (2142), and a plurality of third outflow holes (2146a) are formed to supply rainwater absorbed in the second vegetated soil layer (2242) to another adjacent second vegetated soil layer.

This third panel (2146) is formed at a height equal to or higher than the height of the second vegetation layer (2242) to prevent the vegetation soil of the second vegetation layer from flowing over to another second vegetation layer.

And the first outlet (2142a) is a trapezoidal shape in which the length of the lower side is longer than the length of the upper side, and the second outlet (2144a) is a trapezoidal shape in which the length of the upper side is longer than the length of the lower side.

And the third panel (2146) is further equipped with a baffle (2147) to cover the front side of the rainwater inflow direction of the third outflow hole (2146a). 2147 drawing not shown (confirmed)

When rainwater is moved to the adjacent second vegetated soil layer by this baffle (2147), it prevents the vegetated soil from flowing in together.

In addition, the filter bed (200) further includes a bed infiltration unit (230).

This flower bed infiltration section (230) is provided to allow the rainwater from the filtration space section (202) to infiltrate into the ground.

This flower bed penetration section (230) includes a bottom penetration hole (232) and a crushed stone aggregate layer (234).

The bottom penetration hole (232) is formed in the bottom panel (2148) so that the water in the filter space (202) is discharged downward.

And the crushed stone aggregate layer (234) is formed on the lower side of the bottom panel (2148) so that the rainwater discharged through the bottom infiltration hole (232) can quickly infiltrate into the ground.

Accordingly, rainwater flowing into the first vegetation layer (2222) and the second vegetation layer (2242) can infiltrate into the lower soil.

In addition, the flower bed connecting part (216) is fitted with a plurality of connecting grooves (2162) formed on the outer surface of the post (212).

And, as illustrated in FIG. 5, the penetration section (300) includes a penetration pipe (310), and the penetration pipe (310) has a plurality of penetration holes (312) formed at the other end.

One end of this infiltration pipe (310) is formed to protrude above the vegetated soil layer of the filtration section (200), and the other end is positioned in the surrounding green space.

In other words, when the water level of the filter unit (200) is above a certain level, it is discharged through one end of the infiltration pipe (310) to multiple infiltration holes (312) and infiltrated into the green space ground.

Additionally, the drainage unit (400) includes a drain pipe (410).

One end of this drainage pipe (410) protrudes above the vegetation soil layer of the filtration bed (200), and the other end is connected to a rainwater pipe to drain the water to a wastewater treatment plant.

Here, one end of the drain pipe (410) is formed higher than one end of the infiltration pipe (310).

Looking at the operating state of this filter unit (200), rainwater flowing into the first filter unit (222) is filtered, and some of it is absorbed into the first vegetated soil layer (2222) and infiltrates into the ground through the first outflow hole (2142a).

And the remainder, if it is above a certain level, is supplied to the second filter (224) through the second outlet (2144a).

Some of the rainwater supplied to this second filter (224) is absorbed into the second vegetated soil layer (2242) and supplied to another adjacent second vegetated soil layer through the third outflow hole (2146a), while also infiltrating into the ground through the first outflow hole (2142a).

And, if the remaining water level is higher than a certain level, it seeps into the ground of the surrounding green space through the infiltration unit (300), and if the water level of the second filter unit (224) is higher than one end of the infiltration unit (300), it is discharged into the rainwater pipe by the drainage unit (400) to prevent overflow from the filtration unit (200).
