Description

Rainwater purify type underground penetration device and method of construction thereof

The present invention relates to a rainwater purification type underground penetration device, and more particularly to a rainwater purification type underground penetration device capable of purifying rainwater and penetrating it into the ground and a construction method thereof.

In general, the Korean Peninsula is a region where precipitation is concentrated in the summer, and about 33% of the annual precipitation of about 270 billion tons flows out into the sea, and about 43% evaporates or penetrates underground. The utilization is only about 30 billion tons per year, which is about 24% of the total precipitation.

Despite the fact that it is classified as a poor water resource worldwide due to the loss of rainwater, the technology development and installation of facilities to utilize rainwater are still inadequate in Korea.

Environmentally advanced countries require building owners to collect and utilize rainwater, but typically, rainwater is simply collected in a water tank to be used as garden water, or the collected rainwater is physically purified to be used as laundry or toilet water.

On the other hand, in Korea, there is no water supply facility, and except for areas where rainwater must be collected and used, the rainwater is left to flow into the river or sewage.

Accordingly, in recent years, various technologies have been proposed to collect and utilize rainwater, but most of them emphasize only the penetration function such as water-permeable pavement or penetration ditch installed in the vicinity of green space adjacent to roads, sidewalks, and parking lots.

Incidentally, the rainwater discharged from the sidewalk or the green area has relatively few pollutants, but in the case of initial rainwater, collecting and utilizing it directly without a separate filtration process poses a problem of storage tank water quality management.

Here, in the case of filtering the rainwater flowing out of the sidewalk or green space for the purpose of landscaping water, excessive filtration costs are required, and thus economic efficiency is deteriorated.

That is, since the initial rainwater contains a lot of contaminants, it must be purified to be used as landscaping water, etc., but the mid-term rainwater (中後期雨水) contains less pollutants than the initial rainwater, so simple purification It can be used only for landscaping water.

However, the conventional technologies do not propose a technology or facility for collecting or processing water by distinguishing between early and middle rain.

Therefore, in managing rainwater without using power, it is necessary to develop a technology that utilizes this by separating the initial rainwater and the middle rainwater with a simple principle, and collecting the best rainwater that has been filtered through as much as possible. .
