In addition, the rainwater accommodated in the accommodation part 131 may be temporarily stored in the accommodation part 131, and when the rain stops, the received water may be discharged to a drainage or supplied to the purification system to be recycled.

The discharge part may be located above the accommodation part 131. Accordingly, the discharge unit may be discharged to the external strata 20 when the predetermined rainwater received in the receiving unit 131 exceeds the effective storage capacity. In this case, the rain water discharged through the discharge unit may be configured to be discharged to the ground layer 20 separately from being discharged into the drainage channel through the rainwater discharge unit 150.

In detail, the discharge part may include a plurality of discharge holes 133 so that the rain water is discharged to the outside without passing through the rainwater discharge unit 150 when the rainwater flows in exceeds the effective storage capacity.

Accordingly, the upper portion of the discharge portion constituting the upper surface of the storm storage tank 130 may be formed in a structure capable of supporting the earth pressure or the vehicle load of the upper portion. In addition, the rainwater discharged through the discharge hole 133 may be introduced into the ground layer 20 through the side surface of the rainwater storage tank 130.

Thus, the rainwater treatment structure 100 according to an embodiment of the present invention, through the discharge hole 133 provided in the rainwater storage tank 130, the effective storage capacity in the rainwater storage tank 130 during rain Even when excess rainwater is introduced, the rainwater may be drained to the strata 20 separately from the discharge through the rainwater outlet 150. Therefore, since the amount of rainwater that can be treated in the rainwater storage tank 130 is increased, it is possible to reduce the inflow of rainwater rapidly introduced into the river by local rain or showers, thereby maximizing the flood reduction effect.

On the other hand, the rainwater treatment structure 100 according to an embodiment of the present invention is disposed on the outside of the rainwater storage tank 130, the porous member for providing a gap so that rainwater is easily drained through the discharge hole (133) It may further include 170.

Can be prevented. Therefore, by fixing the porous member 170 around the rainwater storage tank 130, the effect of expanding the effective storage space of the rainwater storage tank 130 can be stably secured.

On the other hand, the rainwater storage tank 130 is installed on the outer circumferential surface or the inner circumferential surface to prevent rain from entering the soil through the discharge hole 133 to prevent the inflow of soil to the inside of the rainwater storage tank 130, And may include 135.

The soil inflow prevention material 135 may be integrally formed inside or outside at the time of forming the storm storage tank 130. In addition, the soil inflow prevention material 135 may be formed of a nonwoven fabric or a nonwoven fabric including a polyester or Teflon-based fiber, the voids are formed therein to allow the discharge of rain water to the discharge hole (133). Here, the nonwoven fabric should be formed so as not to block the outflow of the rain due to the pores blocked by the soil or soil particles mixed in the soil, the outer portion in contact with the ground layer 20 is a void than the inner portion in contact with the rain water By being densely formed, it is possible to smoothly discharge rainwater from the inner side to the outer side, and on the contrary, ocher or soil particles may be prevented from flowing into the rainwater storage tank 130.

However, the installation position of the earth and sand inflow prevention material 135 is not limited to the case shown, various modifications if the earth and sand may not be introduced into the rainwater storage tank 130 through the discharge hole 133. It is possible to implement, for example, it may be installed only on the outside of the portion in which the discharge hole 133 is formed.

On the other hand, one embodiment of the present invention is connected to the rainwater storage tank 130, the pipe 190 is provided with a transfer pump 191 to supply and recycle rainwater contained in the rainwater storage tank 130 to the outside ) May be further included.

At this time, the pipe 190 may be connected to the storage system for storing the purification system and the purified rainwater, it can be smoothly supplied to the purification system and the storage tank by the transfer pump 191.

Accordingly, by collecting and purifying rainwater falling in a relatively clean place of the building in rainy weather it can be recycled for various purposes, such as living water, drinking water, fountains, agricultural water.

In addition, by providing a porous member can increase the rate of rainwater discharged through the discharge hole compared to the case where the outer peripheral surface of the rainwater storage tank is in contact with the strata, the effective storage space of the rainwater storage tank is more porous than the conventional tank capacity The effect of increasing by the space in which the member is disposed can be obtained.
