Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a rainwater retention system for a roadside tree having a trench PC block and a rainwater retention system for landscaping using the rainwater recycle facility system.

The present invention relates to a rainwater harvesting system using a rainwater storage tank capable of storing rainwater in parks where landscaped water is installed or in a ground of India. In particular, the rainwater storage tank can be assembled by assembling a pair of PC blocks, A rainwater pond with a trench PC block that can prevent flood damage due to intensive rainfall and to prevent flood damage by infiltrating nonpolar pollutants contained in incoming rainwater into the surrounding landscape water Landscape Water Rain Storage System.

Rainwater storage is used to prevent flooding and to prevent flooding in the lowlands by reducing rainfall excessively by decreasing the peak discharge during rainfall in case of sudden intensive rainfall due to global warming. This is an approach to overcome the limitations of existing flood control measures centered on excellence exclusion, as the incidence of impervious layer and sudden intensive rainfall due to urbanization increases.

On the other hand, the roadside trees (or landscape water) that have been planted in parks and in India are packed with blocks except for the surrounding part of the base. Therefore, in case of rainy weather, the rainwater can not be stored in the pavement block, the drainage is found by the drainage line, and the roadway only penetrates the rainwater through the unblocked part. Therefore, parks and sidewalks do not have a storage function to temporarily store rainwater, which is one of the causes of flooding in concentrated rainfall.

As an alternative to this, it is required to supply rainwater to the aqueducts in a rainy season and at the same time temporarily collect and store rainwater, and then to cause natural pitching to occur in the ground to prevent flooding damage.

As a background of the present invention, Korean Patent Registration No. 10-1411989, a unit module for a prefabricated rainwater storage tank has been proposed. A unit block including a tube portion in which flow paths in a plurality of directions intersect with each other, and a body portion surrounding the tube portion; A pressure ring having a ring formed at its one end and at its other end with a clearance formed at one end and the other end of the pressure ring and having a clearance adjusting portion for adjusting the clearance of one end and the other end, ; ≪ / RTI >

Therefore, it can be applied flexibly according to the size and range of the construction site by stacking and assembling standardized unit blocks having a rectangular parallelepiped shape, and is excellent in versatility and has an advantage of excellent workability on site and economical efficiency.

However, the above background art has a problem in that watering occurs in landscaping water and roadside trees during a rainy season and it is difficult to apply them to parks or indoors because there is no function to temporarily store them.

As another background art of the present invention, Korean Patent Registration No. 10-1510615 discloses an infiltration rainwater storage tank and a construction method thereof. A rainwater storage unit having a lower plate and a rectangular, tubular shape having a front wall, a rear wall, a left wall, and a right wall vertically coupled to the front, rear, left, and right sides of the lower plate; A partition wall vertically installed in the rainwater storage part to divide the rainwater storage part; An upper plate coupled to the upper side of the rainwater storage unit and covering an upper portion of the rainwater storage unit; And a rainwater inflow part provided on the upper part of the upper plate and composed of a normal wall, a top rear wall, a top wall, and a top and bottom wall and having a hollow square pillar shape, and the top plate is connected to the rainwater storage part And the bottom plate includes a drain hole into which the inflowing rainwater can penetrate into the underground. The bottom plate includes a through hole through which the introduced rainwater can flow.

Therefore, rainwater flowing out of the impermeable surface at the time of rainfall is rapidly inflowed and stored, and then flows into the ground with time, thereby providing an effect of preventing urban flooding and improving the water circulation system of the city due to depletion of groundwater.

However, the latter background technology has a disadvantage in that the infiltration stormwater storage tank can not be utilized as a drainage-type stormwater or for the purpose of storing rainwater around the landscape water.
