Description

Technical Field [0001] The present invention relates to a rain garden construction method having vegetation growth promotion and non-point pollution reduction,

The present invention relates to a method of constructing a rainwater garden facility, and more particularly, it relates to a method of constructing a rainwater garden facility, in which water stored during rainy season is continuously supplied to planted plants to promote vegetation growth and natural evaporation of water to lower the temperature rise, The present invention relates to a method of constructing a rainwater garden facility having acceleration of vegetation growth and reduction and elimination of non-point pollutants so as to achieve reduction of nonpoint pollutants by adsorption.

Generally, landscaping facilities and green spaces are created with the meaning of landscaping. These landscaping facilities and green spaces 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. Therefore, rainwater utilization, groundwater filling, temperature reduction and carbon emission reduction are actually required.

On the other hand, in places where apartments and other housing complexes are constructed, they usually plant vegetation to make gardens. At this time, the vegetation is selected to withstand the watering season because it is not necessary to manage the water. Therefore, there is a difficulty in planting plants that require a lot of water and decorating the garden. In particular, since a separate water supply system is not generally provided in a garden using rainwater, a temperature reduction effect due to the garden can not be obtained.

Korean Patent Registration No. 10-1300796 (a lane garden system for selective treatment and recycling of rainfall runoff) has been proposed as a background of the present invention. A first water channel connected to the rainfall inflow water inflow section and the rainwater inflow water inflow section to transfer the rainwater runoff to the stormwater channel, a second water channel installed at one side of the first water channel, a connection section connecting the first water channel and the second water channel, And a rain garden connected to the second water channel and arranged in a flow of vegetation to separate an initial rainfall runoff and an initial rainfall runoff to separate an initial rainfall runoff from the rainfall runoff, The rainfall runoff can be selectively treated by using rainfall runoff, and the rainfall runoff can be selectively treated. In addition, the urban landscape can be saved, and water resources can be secured by storing the rainwater in the reservoir. .

However, the above background technique is capable of storing a certain amount of rainwater after rainstorm, but does not provide a means for continuously supplying the rainwater to the vegetation.

Another technology to be a background of the present invention is Korean Patent Registration No. 10-1245865 (Rotary ecological complex biotension facility for intersection non-point pollution treatment), which is provided in the form of a ring on the outer side, A waterway; A vegetation infiltration water line provided in the inside of the filtration infiltration channel and filled with vegetation soil and planted with vegetation; And an infiltrating rain garden which is provided in the inside of the vegetation infiltration channel and filled with vegetation soil and planted with vegetation. Therefore, effective treatment of inflow water such as rainfall runoff and urban landscape can be satisfied at the same time, To be able to do.

However, even in the case of the background art described above, there has not been proposed a system for continuously supplying moisture to the vegetation flow after rainstorm.

As another background of the present invention, Korean Unexamined Patent Application Publication No. 10-2013-0134271 (roadside rainwater infiltration storage facility) has been proposed. 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 submerging it into the ground

 However, even in the case of the background art described above, rainwater flowing out from the road surface is quickly re-infiltrated into the ground, while it is difficult to continuously supply water to the vegetation after rain, It takes a long time to construct and there is a problem that the construction cost rises.
