Description

Drainage Kerb has filtering function of Non-point pollutants}

The present invention relates to a drainage device for both road curbs and, more specifically, to a drainage device for both curbs that can effectively filter non-point pollutants contained in rainwater while minimizing the inflow of foreign substances such as cigarette butts and fallen leaves.

In general, road boundary stones installed around general roads (roadways) had no particular function other than the very simple function of being used as boundary stones for the sidewalk (10) and the roadway (50). Therefore, when it rains, not only rainwater (rainwater) but also other foreign substances contained in the rainwater (e.g. fallen leaves, cigarette butts, household waste, etc.) and non-point pollutants are flowing into the rainwater gutter installed on the roadway 50. In addition, if the rainwater catch basin of the point drainage system becomes clogged with foreign substances (fallen leaves, cigarette butts, etc.), the road surface may become slippery due to rain, which may pose a risk of safety accidents while driving, and when heavy rain falls during the rainy season, the road becomes damaged. Cases of complete flooding occur frequently. In addition, there are cases where rainwater or wastewater from the road surface that is not discharged when the vehicle is running splashes onto the sidewalk 10 and touches pedestrians. Therefore, it has been necessary to clean rainwater drains (sumps) on a regular/irregular basis.

Meanwhile, various types of nonpoint or diffuse source pollutants of unknown origin are scattered on the roads. These non-point pollutants include various pollutants emitted from vehicles (engine oil, etc.), tire fragments/dust, vinyl/plastic fragments, snow removers, heavy metals, and suspended solids. When it rains, non-point pollutants are polluted by existing rainwater gutters/sumps. This was pointed out as a cause of river pollution as it flowed into the drain along with rainwater.

To solve this problem, a large-scale non-point pollution reduction facility was installed separately to collect rainwater in a tank and purify it. This required a huge amount of cost, space, manpower, and time, and there was a demand to come up with an efficient method for this. come.

Republic of Korea Patent Registration No. 10-0612080 (Road boundary stone structure for drainage treatment), 3. Republic of Korea Patent Registration No. 10-1874284 (Rainwater circulation system equipped with drainage road curbs for rainwater storage).

Therefore, the present invention was created to solve the above problems, and the first object of the present invention is to apply a linear drainage method to rainwater on the road surface rather than a point drainage method using existing rainwater gutter/sump wells, It not only prevents road surface flooding by increasing drainage efficiency by minimizing the phenomenon of rainwater drains/sumps becoming clogged with foreign substances such as cigarette butts and fallen leaves, but also provides a drainage device that can be used as a boundary stone to filter out non-point pollutants contained in initial rainwater. It is done.

The second object of the present invention is to provide a drainage device that can filter non-point pollutants that is easy to clean and maintain by having an openable cover.

The third object of the present invention is to provide a drainage device that can filter non-point pollutants that can contribute to recycling of resources and environmental protection by manufacturing using waste plastic.

However, the technical problems to be achieved in the present invention are not limited to the technical problems mentioned above, and other technical problems not mentioned will be clearly apparent to those skilled in the art from the description below. It will be understandable.

In order to achieve the above technical problem, the main body 200 is formed with an inlet 210 through which rainwater flows in on one side, and forms a cavity 240 therein; A cover 110 covering the upper surface of the main body 200; A filter media 270 provided at a first predetermined height H1 inside the cavity 240 to filter non-point pollutants contained in rainwater; and a water pipe 320, one end of which is included in the filter medium 270 and the other end of which is connected to the water collection well 300. A boundary stone combined drainage device capable of filtering non-point pollutants is provided.

Additionally, the inlet 210 has the shape of a plurality of vertical slots and may be curved toward the roadway 50.

Additionally, the slot width of the inlet 210 is 6 to 8 mm.

Additionally, the cover 110 is detachable.

Additionally, the upper surface of the cover 110 may further include at least one of a protrusion 120 to prevent pedestrians from slipping or a reflective tape 125 for drivers.

In addition, it further includes an overflow pipe 330, one end of which is located at a second predetermined height H2 from the upper surface of the filter medium 270, and the other end of which is connected to the water collection well 300.

Additionally, the first predetermined height (H1) is in the range of 10 to 20 cm, and the second predetermined height (H2) is in the range of 10 to 15 cm.

In addition, a male connection portion 250 formed at one end of the main body 200 along the longitudinal direction of the boundary stone; and a female connection part 260 formed at the other end of the main body 200 and adapted to the shape of the male connection part 250 to enable continuous construction of the drainage device 100.

Configuration of the Example

Hereinafter, the configuration of the preferred embodiment will be described in detail with reference to the attached drawings. Figure 1 is a perspective view of a drainage device for curbstones capable of filtering non-point pollutants according to an embodiment of the present invention, and Figure 3 is a cross-sectional view of the installation of the drainage device 100 shown in Figure 1. As shown in Figures 1 and 3, the boundary stone drainage device 100 has a substantially rectangular parallelepiped shape, and its interior forms a cavity 240. This drainage device 100 can be completed by integrally injecting polypropylene and/or waste plastic or by assembling it after injection. The size of the drainage device 100 can be manufactured to have a length × height × width of approximately 1,000 × 600 × 300 mm, and can be manufactured according to road curb installation standards and performance standards (e.g., 1,000 × 600 × 200, 1,000 × 600 × 250, 1,000 × 550 × 200, etc.)

The cover 110 has a square shape located on the upper surface of the main body 200, and protrusions 120 are regularly protruded from the upper surface of the cover 110 to prevent pedestrians from slipping. Additionally, attaching a reflective tape to the side edge of the roadway side of the top of the cover 110 or the drainage device 100 increases driver visibility at night. In other words, as the light emitted from the vehicle or surroundings is reflected, drivers and pedestrians can clearly recognize the location and outline of the boundary stone. This cover 110 may be injected from polypropylene and/or waste plastic and then assembled. The cover 110 may be opened and closed by installing a hinge on one side, opened and closed in a sliding manner, fitted with a hook, or fastened with a bolt. When the cover 110 is opened, the inside of the cavity 240 can be easily accessed.

The inlet 210 is formed on the side of the main body 200 and is an area exposed to the roadway 50. The inlet 210 has vertical slots formed closely, and the slot width of the inlet 210 is 6 to 8 mm. If the slog width is less than 6 mm, rainwater does not flow smoothly during heavy rains such as during the monsoon season, and if it exceeds 8 mm, cigarette butts, fallen leaves, and trash are likely to flow in. In one embodiment of the present invention, the slot width was defined as 7 mm.

FIG. 4 is an installation plan view of the drainage device 100 shown in FIG. 1. As shown in FIG. 4, the main body 200 in the area of the inlet 210 protrudes toward the road in the form of small triangular or oval irregularities where the fleshy portion between the slot openings is small. In this way, the protruding inlet 210 has the effect of allowing fallen leaves 55, etc. to be scattered rather than adhered to each other. This drainage device 100 can be installed continuously in the required quantity along the longitudinal direction.

Four to six recessed portions 220 are installed in the lower or rear surface of the recessed portion 220 of the main body 200. The mortar 280 flows into the depression 220 and is fixed thereto, thereby firmly fixing the position of the drainage device 100.

The purified rainwater conduit pipe 320 is installed in the lower area of the filter medium 270 of the main body 200, and the overflow pipe 330 is installed in the upper part of the filter medium 270.

Both sides of the main body 200 are open, and one side is provided with a protruding male connection part 250, and the other side of the main body 200 is provided with a female connection part 260 that is shaped to fit the male connection part 250. do. Therefore, two or more main bodies 200 can be constructed continuously by combining the male connection part 250 and the female connection part 260. A sealant (eg, rubber, silicone, etc.) may be provided between the male connection part 250 and the female connection part 260.

The filter medium 270 is laid in the cavity 240 inside the main body 200 at a first predetermined height H1. This first predetermined height (H1) may be in the range of 10 to 20 cm. The filter medium 270 is in the form of fine particles with a high specific gravity and filters non-point pollutants flowing in with rainwater. This filter medium 270 must have both high permeability for rapid drainage and excellent pollutant filtration performance, and must also have a high specific gravity so that it is not easily swept away by rainwater. For this purpose, the filter medium 270 is in the form of sand particles with a size of 0.006 to 0.060 mm, and filters non-point pollutants flowing in with rainwater. This filter medium 270 can be manufactured by mixing rubber, synthetic resin material, ceramic raw materials (e.g., clay, limestone, silica, etc.), and adhesive, or by mixing natural engineered bio-remediation soil.

One end of the water pipe 320 is located below the filter medium 270, and the other end is exposed to the outside of the main body 200 and connected to a nearby water collection well 300. Accordingly, rainwater in which non-point pollutants have been filtered flows into the water collection well 300 through the water pipe 320 and is then sent to the rainwater pipe 310. These water collection wells 300 and/or rainwater pipes 310 may be existing facilities.

One end of the overflow pipe 330 is located at a second predetermined height H2 from the upper surface of the filter medium 270, and the other end is connected to the water collection well 300. This second predetermined height (H2) is in the range of 10 to 15 cm. The overflow pipe 330 is a structure for discharging rainwater overflowing from the cavity 240 to the top of the filter medium 270. When it starts raining, the initial stormwater contains many non-point pollutants. Therefore, the initial rainwater is intensively filtered by the filter media 270. In addition, when rain continues, the amount of non-point pollutants in the rainwater is small, so there is a low risk of environmental pollution even if the rainwater that has not been filtered is discharged through the overflow pipe 330. Accordingly, the second predetermined height H2 can be adjusted by taking into account the volume of the cavity 240, the permeability of the filter medium 270, the filter media capacity, etc. For example, in the case of large city centers or downtown areas, there are a lot of non-point pollutants, so the first prescribed height (H1) can be increased to 15 to 20 cm, and in residential areas, since there are few non-point pollutants, the first prescribed height (H1) can be increased to 15 to 20 cm. It can be lowered to 10 to 15 cm.

FIG. 2 is a diagram showing the installation state of the drainage device 100 shown in FIG. 1. As shown in FIG. 2, the drainage device 100 may be constructed singly, continuously, or at regular intervals between stone boundary stones 30 such as granite. And the height difference between the roadway 50 and the sidewalk 10 can be 200 to 300 mm depending on the road border height standard. As shown in Figure 2, the cover 110 is located on the same plane as the sidewalk 10, and the lower part of the main body 200 is buried so that only the inlet 210 of the main body 200 is exposed to the road.

Meanwhile, on a straight road or a curved road, a separate adapter (not shown) made of synthetic resin may be placed between the drainage device 100 and the stone boundary stone 30 to increase the fixing force.

Figure 5 is a front view of the side finishing cap 350 according to the present invention. As shown in Figure 5, the side finishing cap 350 is a plate-shaped member, and a male connection part 250 or a female connection part 260 is formed on one surface to finish the side surface of the main body 200. This can be done by closing the cavity 240 or connecting a pipe by drilling a hole in the side closure cap 350 to connect to an existing rainwater pipe.

Operation of the Embodiment

Hereinafter, the operation of the preferred embodiment will be described in detail with reference to the attached drawings. When it starts to rain, initial rainwater, cigarette butts, fallen leaves (55), and non-point pollutants collect near the inlet (210) according to the flow of rainwater. At this time, due to the protruding structure of the inlet 210, trash such as cigarette butts and fallen leaves 55 do not gather in one place, but are scattered, and do not pass through the inlet 210.

Initial rainwater, including non-point pollutants, falls within the cavity 240 and onto the filter media 270. In addition, non-point pollutants are filtered by the filter media 270 and remain, and only the filtered initial rainwater is discharged from the lower part through the water pipe 320 to the water collection well 300 and the rainwater pipe 310. Therefore, no sedimentation occurs in the water sump 300 and the rainwater pipe 310, and the cross section can be maintained. Additionally, the filter medium 270 whose expiration date (e.g., 5 to 10 years) has passed can be replaced or replenished by opening the cover 110.

As rainfall continues and the amount of rainwater flowing in increases, the height of the rainwater rises above the filter media 270. Stormwater after initial rainfall contains low amounts of nonpoint pollutants. Therefore, rainwater that has not passed through the filter medium 270 may be discharged directly into the water pipe 320 and the rainwater pipe 310 through the overflow pipe 330. Therefore, through the embodiment of the present invention, a large amount of non-point pollutants contained in the initial rainwater can be filtered, but there is an efficiency in not having to filter all the rainwater. In other words, it is possible to distinguish between initial rainwater and rainwater after the initial stage and filter non-point pollutants in the initial stormwater.
