BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a water purifier,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

Drainage is installed on the pavement for rapid drainage of rainwater. Generally, the drainage facility is constructed such that a drainage pipe connected to the river is buried in the ground of the pavement, a house correction (also referred to as rainwater catching) is provided at the edge of the pavement, It is connected to the drain pipe. As a result, in the case of rain, the rainwater falling on the pavement flows to the edge of the road and flows into the house correction. The rainwater flowing into the house correction flows into the drainage pipe through the connection pipe while the house is being cleaned. Is drained to a river or the like along a drain pipe line.

However, such a drainage facility can discharge the rainwater to the river quickly without raining the rainwater when the rainfall occurs. However, recently, as the surface of the ground surface is rapidly packed, the underground water infiltration into rainwater is reduced, have. Depletion of groundwater causes ground subsidence, and in the case of a region close to the coast, groundwater disturbance occurs such as groundwater desalination due to reverse osmosis of seawater.

Recently, permeable concrete has been developed for infiltration of rainwater into underground, and it has been applied to packaging of roads and plazas. However, most of the rainwater falling down from the pavement concrete pavement layer to the underground water flows to the edge of the road and is discharged to the river through the drainage line buried in the ground.

On the other hand, the pavement has accumulated a lot of pollutants such as soil, organic matter, tire dust exhaust gas dust and the like, and these pollutants are introduced into the house with rainwater. These contaminants are contained in the initial rainwater at a high concentration and are introduced into the collecting house. As time passes, the concentration of pollutants contained in the rainwater decreases. Pollution inflow into the river is likely to cause water pollution if it flows into the river without being purified.

Korean Patent No. 10-0892834 (hereinafter referred to as "prior art") discloses a technique for removing initial rainwater from a sedimentation basin by detachably installing a sedimentation baskets in a house fixation. . However, the prior art is disadvantageous in that, when a large foreign object such as a cigarette butt is accumulated in the sedimentation basin, the rainwater can not flow into the house and floods the road.

An object of the present invention is to provide a water collecting fixture having a water purifying function for sufficiently draining rainwater introduced from a road into a river while draining it into a river.

It is another object of the present invention to provide a water collecting fixture having a water purifying function for purifying contaminants contained in initial rainwater as well as discharging rainwater into a basement and a river smoothly without overflowing the road.

In order to accomplish the object of the present invention, there is provided an aggregate upper body which is formed of plain concrete; A corrugated bottom body formed of a water permeable concrete and connected to a lower end of the corrugated upper body; A fastening unit for fastening the collecting upper body and the collecting lower body; And a water purification unit detachably installed in the water collection upper body for sequentially filtering rainwater flowing into the water collection upper body, wherein the water purification unit is provided in an upper portion of the water collection upper body, A first filtration body for filtering rainwater flowing into the collecting upper body and a rainwater which is provided inside the collecting upper body so as to be positioned below the first filtering body and overflows over the first filtering body, And a second filter body is provided.

Wherein the collecting upper body has a tubular shape with a horizontal sectional shape in the longitudinal direction and the collecting lower body includes a bottom portion and an upper surface of the bottom portion, And the horizontal cross-sectional shape of the extension pipe is the same as the horizontal cross-sectional shape of the collecting upper body.

The bottom portion of the corrugated bottom body may include a drain hole formed in an inverted conical shape at a center portion thereof, a stopper for opening and closing the drain hole, and a hooking member provided on the stopper for lifting the stopper.
