Description

[0002] Expansion infiltration pot pacility for plant growth by surface detention storage and evaporation, which allows vegetation growth by storage and evaporation due to rainwater infiltration,

The present invention relates to a pollen facility installed in a green house or a landscape facility of a multi-family housing complex, and more particularly, to an apparatus for enhancing permeability of rainwater and being used as a storage facility, capable of reducing non-point pollutants contained in rainwater, The present invention relates to an expandable infiltration plant facility capable of supplying infusions.

Generally, landscaping facilities and green spaces are created with the meaning of landscaping. These landscaping facilities and green spaces only perform simple landscaping functions such as vegetation and shrubs.

On the other hand, Korea is classified as a water-scarce country, and carbon emissions are gradually increasing, so rainwater utilization, groundwater filling, temperature reduction and carbon emission reduction are required.

Especially when rainwater falls in the atmosphere, it is in a relatively clean state. However, if it touches the surface of the earth once, it will pollute various pollutants such as ground (urban residence, commercial district, industrial complex roads, sewer and river, polluted rice fields and farmland contaminated with chemical fertilizers in rural areas) And becomes a waste water (sewage). Therefore, there is a need for a landscape or green space facility that can combine rainwater contamination and rainwater harvesting.

As a background of the present invention, Korean Patent Laid-Open Publication No. 10-2013-0134271 has proposed a rainwater infiltration storage facility on the road side. This is because the rainwater flows into the pretreatment tank; An upper structure for discharging the rainwater discharged from the pretreatment tank to the lower structure; A flooding trough which flows rainwater exceeding a capacity that the upper structure can contain and flows out to the lower structure; And a substructure for storing rainwater and infiltrating the ground underground. However, the above-mentioned technology performs a storage tank function capable of quickly penetrating rainwater into the underground, but it does not have a water evaporation structure and it is difficult to plan vegetation growth.

As another technology to be a background of the present invention, Korean Patent Registration No. 10-1288906, 'penetration ditch' has been proposed. A pretreatment tank having an inflow hole formed bottom and an upstream wall to which the inflow pipe is connected and a downstream wall having a to-be-treated water transfer hole and an overflow portion; A house having a bottom formed with a penetrating hole, an upstream wall having a treated water transfer hole and an overflow portion, and a downstream wall connecting the discharge pipe; Further comprising a filtration tank provided between the pretreatment tank and the collection tank and having a bottom having a penetrating hole formed thereon and disposed in the pretreatment tank to filter contaminants mixed in the inflowed water to be treated, A filtration and backwashing pipe which is seated on the bottom of the pipe; A backwashing tube insertion hole formed at a lower end of the upstream wall of the collecting tube and downstream of the pretreatment vessel corresponding to both ends of the filtration and backwashing tube; And a stopper for opening and closing the backwashing spraying tube insertion hole. However, the above technology is difficult to carry out the storage tank function by draining the infiltration rainwater into the ground water, and there is no evaporation structure of water, so that it is difficult to grow the vegetation.

Another technology to be a background of the present invention is Korean Registered Patent Registration No. 10-1345009. In the structure having a non-point pollution abatement facility, the initial effluent of the rainwater flowing into the existing water channel is separated into a separate water distribution channel An inflowing flow distribution structure; A pretreatment tank in which the initial effluent led to the flow distribution structure flows into the bottom and the pollutants contained in the initial effluent are settled down; And an infiltration ditch that inflows the initial effluent stored in the pretreatment tank and infiltrates and infiltrates the initial effluent into the aggregate by filling the aggregate inside the infiltration trench. The above-described technique can reduce the non-point pollution by allowing the initial effluent to be removed from the non-point pollution to flow into the pretreatment tank, allowing the initial effluent stored in the pretreatment tank to gradually flow into the infiltration trench, It is difficult to plan vegetation growth.
