The present invention relates to rainwater storage and a system for filtering the rainwater to induce underground penetration. More specifically, temporary storage of rainwater and the rainwater are filtered to induce penetration into the ground, thereby ensuring a good water resource and flooding. And flooding induction systems of rainwater that reduce flood damage and normalize water circulation to protect natural ecosystems.

Recently, the United Nations (UN) announcement warns that Korea will become a water shortage nation that lacks water. This is also due to the regional nature of precipitation during the summer months, but can also be attributed to the lack of a systematic system for water management.

In other words, as the city develops, the building area increases, and as the roads are paved, the amount of water penetrating into the basement decreases sharply in proportion to the decrease of the permeation area, and the groundwater gradually becomes depleted and the water supply becomes difficult. As a result, the plant is difficult to grow, the soil ecosystem is destroyed, and there is a problem that adversely affects the river ecosystem while increasing the browning phenomenon.

In addition, an increase in the impervious surface area causes flooding of lowland areas during heavy rainfall, and there is a risk of flooding the river.

In addition, the pollution of the environment includes inorganic and organic pollutants in the rainwater that has passed through the atmosphere and the surface, and infiltrates the soil and the groundwater by penetrating underground when they are included.

Therefore, in recent years, repair facilities have been expanded and various devices for treating rainwater have been developed. For example, the rainwater treatment system of Korean Utility Model Registration No. 356887 collects rainwater and purifies it so that it can be used as water.

Such a system includes a reservoir for removing large contaminants, soils and suspended solids from the collected rainwater, and storing it, a microfilter for pumping rainwater stored in the reservoir to remove the turbidity component, and a second filtration treatment for the rainwater. It consists of an activated carbon filter, a storage tank for secondary storage of the filtered rainwater, an oxidation treatment device for sterilizing / disinfecting and deodorizing the rainwater in the storage tank using ultraviolet rays and ozone, and a device for sending the rainwater.

However, such a device has a problem that the system is large as a whole, as the rainwater is temporarily collected and stored, it is difficult to manufacture and the construction cost is excessive. In addition, these systems can only be used in certain installed areas, it is difficult to manage water systematically, it is difficult to protect the natural ecosystem by circulating water naturally, and there is no utility for solving the water shortage fundamentally. have.

The present invention has been made in view of the above-mentioned conventional problems, and its object is to increase the water permeation area of the city so that the water circulates naturally to protect the natural ecosystem, and to reduce the water shortage of rainwater and this rainwater can be eliminated. The present invention provides a system for filtration to induce underground penetration.

Another object of the present invention is selectively installed in a number of places, such as detached houses, apartments, roads, parking lots, parks, etc. in consideration of precipitation, initial precipitation or vertical precipitation, and various inorganic and organic pollutants included in rainwater. It is to provide an excellent underground penetration induction system that can be filtered to prevent contamination of soil and groundwater.

Another object of the present invention is to increase the permeation area to prevent the depletion of groundwater, to protect the river ecosystem, as well as to allow rainwater to circulate even during heavy rains can prevent flooding and lowland flooding of lowlands It is to provide an excellent underground penetration induction system.

The present invention is to embed the filter layer in the inner space of the manhole or around the manhole by embedding the manhole, and planting trees or various plants on top of the filter layer, but the non-woven fabric is laid between the filter layer and the existing soil It has technical features to prevent mixing.

Preferably, the manhole is composed of at least two or more stages to be laminated or integrally formed, but drain holes are formed in the main wall to drain the filter layer located around the manhole so that the pollutants are filtered through the filter. It has a configuration that allows penetration into existing soil.

In addition, the manhole of the present invention is configured with and without a bottom, and a separate filtering means may be installed therein to improve the purification efficiency.

On the other hand, the system of the present invention may be divided into a predetermined area on the road or sidewalk, and may include a reservoir therein, and be dug along the road or install a reservoir in an existing ditch to be contaminated by filter layers and humus soil deposited on these upper sides. The material is filtered, and the technical characteristics of the flow control and storage are achieved by covering the mound on the upper part of the humus and constructing the pond.

Hereinafter, preferred embodiments of the present invention will be described in detail.

Preferably, the present invention is a facility for infiltrating rainwater collected in a rainwater channel or a water channel of a classified pipeline system or a water channel through a soil layer.

In the present invention, the inorganic and organic contaminants present in various forms in the rainwater are largely removed in advance, and secondly, the residue is removed while passing through the soil filtration layer, and the sedimentation and contaminants are removed using a screen and gravity settling. Colloidal particles and liquid phases are removed through reactions such as filtration, adsorption, diffusion, and ion exchange while passing through the soil filter layer.

In the present invention, the soil used as the filter material in the stormwater penetration facility should have a constant penetration coefficient (Cr), and for the stormwater penetration facility, if the permeability coefficient of the existing soil is Cr <1 · 10 ^-7 m / s, At least Cr> 1 · 10 ^-4 m / s shall be maintained.

According to the pitcher coefficient

Cr = 5 · 10 ^-3 m / s is a very good permeability coefficient,

Cr = 5 · 10 ^-6 m / s has a very low permeability coefficient,

Cr = 2 · 10 ^-6 m / s is divided into the lowest permeability coefficient and the minimum available soil.

In addition, when the rainwater penetrates into the basement, a sufficient review of the damage to the neighboring buildings, etc. should be preceded, and the material that contaminates the groundwater should be removed beforehand.

It is desirable to maintain a distance of about 1.5m or more from the bottom of the permeation facility to the highest groundwater level to secure a soil filter layer of sufficient thickness to remove contaminants.

1-4 are appended to a system that enables rainwater storage and underground penetration using manholes.

First, the embodiment of FIG. 1 is installed in a drainage area having a relatively small amount of rainwater, such as a general detached house and a townhouse. Preferably, the permeability coefficient C _f = 1.10 ^-5 m / s or more of the existing soil is appropriate.

The manhole 10 is divided into at least two stages, and the upper and lower manholes 11 and 12 are assembled in a stacked form, and there is no bottom blocking the bottom so that rainwater can flow out, and the internal space ( 12) is a configuration in which the mixed gravel, ie, the filter layer 20, made of gravel and sand is filled.

In other words, the manhole 10 is dug out the ground and then laid a non-woven fabric 30, the mixed gravel to a certain thickness thereon and the manhole 10 to be constructed, the inner space of the manhole and the filter layer ( Fill in 20).

Here, the nonwoven fabric 30 is to prevent the permeability and the storage capacity from being reduced by preventing the existing soil 1 from being mixed with the filter layer 20 so that the pores of the filter layer 20 are not closed. The upper part of the filter layer 20 is planted with various plants or trees to help the beautification of the environment, to help microbial habitat in the root portion and to increase the evaporation.

After the construction of the manhole 10, the top of the manhole is finished with existing soil and road pavement / or humus layer.

On the other hand, the manhole 10 is preferably prefabricated by pouring concrete, but may be manufactured by synthetic resins, etc. In some cases, the lower manhole 12 has a plurality of drain holes 14 in equal intervals or irregular intervals Perforated to allow drainage through it.

In addition, the rainwater inlet pipe 15 is connected to the upper side manhole 11 so that rainwater flows through it, and in addition to the water pipe 15, the rainwater is also excellent through the chain 4 connected to the roof drip tray 3. Is configured to inflow.

The induction system of this configuration is such that the rainwater flowing down from the inlet pipe 15 or the drip tray 4 is removed to the contaminants while passing through the inside of the manhole 10, that is, the filter layer. It is drained so that the water level and the degree of filtration are controlled.

2A and 2B show another form of manhole according to the present invention.

The manhole 100 is for removing contaminants and solids in rainwater, preferably by removing them and then discharged to the above-described underground penetration system or recycling facility, rivers, thereby preventing the contamination of groundwater and rivers to protect the natural ecosystem It is a manhole.

The manhole 100 is made of a prefabricated concrete structure, having a reservoir 110 to collect rainwater therein, the inlet pipe 120 is connected to the rainwater to the upper one side of the inlet pipe 120, In other words, the blocking plate 121 is installed in the water tank so that the flow of rainwater is dispersed.

In addition, the rainwater induction pipe 130 is installed in the central portion of the manhole 100 is connected to the discharge pipe 140, that is, the inner side of the induction pipe 130, that is, the filter plate (connecting portion of the discharge pipe 140) ( 131) is installed to prevent the passage of debris, such as fallen leaves.

Here, the upper side of the manhole 100 is provided with a lid to periodically remove the precipitate by the tank car.

The manhole 100 of this structure is dispersed as the rainwater flowing through the inlet pipe 120 hits the primary blocking plate 121 so that the sediment sinks to the bottom, and the suspended solids and light oil flow into the water surface. When it rises, it is difficult to be discharged through the induction pipe 130, and contaminants such as fallen leaves are filtered out of the filter plate 131, so that the clean rainwater is discharged.

3A and 3B show an example of a filtration means 200 installed at a central portion of the manhole 100 as described above or separately installed to filter rainwater.

The filtering means 200 is to be constructed to improve the processing efficiency of rain, it is composed of a cylinder 210 constituting the outer wall, and a support leg 220 to support the cylinder 210 to enable construction, The inflow passage 221 communicates with the lower side of the cylinder 210 between the leg and the leg is configured to allow the rain to flow through it.

The inside of the cylinder 210 is filled with a media-filled filter 230 to filter contaminants contained in the rainwater, but the lower portion of the filter layer 230, that is, the bottom of the cylinder 210, is separately provided as necessary. The plate 240 may be installed to allow the filter 230 to be cleaned, replaced, or the like.

Filtration means 200 having such a configuration is used in the manhole form independently or installed in the reservoir 110 of the manhole 100, when installed in the manhole 100, rainwater inlet pipe 120 Inflow to the primary blocking plate 121 and hits the flow direction is changed along with the change and the sediment is settled to the bottom. In addition, the rainwater collected in the reservoir is introduced into the cylinder 210 side of the filtration means through the inflow passage 221 and drained to the outside after the secondary filtration process again in the filter layer 230. Of course, the upper one side of the cylinder 210 is provided with a drain pipe 211 so that the filtered rainwater can be drained.

The filter layer 230 is expelled by the reaction of filtration of rainwater, adsorption of contaminants, diffusion, ion exchange, and the like, and the rainwater processed through these waters has good water quality so that recycling or underground permeation is intact.

Meanwhile, the cylinder 210 and the filter 230 of the filtration means 200 are just one example, and may be manufactured by different shapes, structures, and materials.
