Description

{Eco-friendly Rain-water Retaining Facility for Keeping Water in Ground}

The present invention relates to an eco-friendly underground low water stormwater storage tank for collecting and purifying rainwater discharged from roads, parking lots, open spaces and roofs.

In addition to economic growth, Korea has been focusing on the rapid urbanization of rainwater in the past, rather than infiltration of rainwater into the ground. As a result, if a large amount of rain continues, disasters such as flooding of rivers and sewers are occurring. The rainfall per capita in Korea is one eighth of the world average, which is very small, and rainwater is a valuable resource, but it is exporting it too quickly. Therefore, it is necessary to change the perception of rainwater and to use it effectively

Underground low water storm reservoirs are designed to store rainwater underground and use it effectively when needed. The stored rainwater has the effect of preventing the purification of the river and the natural waters caused by the reduction of the groundwater to the ground water as well as the use of the green water, the water of the toilet, the emergency water for the disaster,

However, in the conventional underground low-rainfall storm reservoir, most of the rainwater contaminated with mud or the like as in Patent No. 10-1003526 is collected and stored without being purified separately. However, since the contaminated rainwater is stored as it is, it is difficult to recycle the rainwater. Also, mud is deposited inside the storage tank, which makes it difficult to manage the storage tank.

The present invention has been developed to improve the disadvantages of conventional underground low water stormwater storages, and it is a technical problem to provide a new storm water storer that can effectively purify and store rainwater and is easy to maintain.

According to an aspect of the present invention, there is provided a subterranean low rainwater stor- age tank for collecting and purifying rainwater from a ground, comprising: a collecting part for collecting foreign matter into the lower part of the sinker through rainwater; An integer part of which the rainwater flowing into the water collecting part is transferred and is upwardly filtered by the filter; A water reservoir in which a sieve member filled with a porous tube is filled in a space covered with a car body material and the upwardly filtered rainwater in the purified water portion is transported downward along the sieve body to be stored in the body material; And a drain connected to the bottom of the bottom of the bottom of the water reservoir and provided for recycling the rainwater stored in the bottom reservoir.

According to the present invention, the following effects can be expected.

First, regeneration and effective utilization of limited water resources are possible, and the environment can be promoted. Particularly, it is possible to effectively remove pollutants and oil contained in rainwater, thereby contributing to the conservation of surrounding water bodies and the reduction of the load on the sewage treatment plant, and the processed rainwater can be stored and reused to realize effective use of water resources.

Secondly, it is possible to store a large amount of rainwater because it uses a porosity pipe capable of securing 90% or more of porosity as a body material of the reservoir. In particular, since the pipe structure is installed in a continuous structure, the internal void ratio is high, so that a large amount of rainwater can be stored and water can be flown in a short time.
