れる。(Operation) According to the present invention having such a configuration, firstly, in the first invention, the rainwater flowing down from the rain gutter passes through the permeation hole provided in the rainwater discharge pipe in the process of flowing down the rainwater. Part of the rainwater that reaches the filter layer through the rainwater discharge pipe while being absorbed by the absorber is absorbed by the rainwater absorber and the filter layer because the rainwater absorber is installed inside the filter layer. It is absorbed and stored in the inside in a saturated state. On the other hand, rainwater corresponding to the supersaturated water content of the filter layer is discharged from the drain pipe. The rainwater absorbed by the rainwater absorber is directly in contact with the backfilled sand layer in which the rainwater absorber is buried, so the water evaporates from the ground surface and changes underground. Depending on the change in the water content of the rainwater, it penetrates into the layer of backfilled earth that is in direct contact with it, and the rainwater that is absorbed and stored in the rainwater absorber in a state close to the natural world is treated.

砂の層の中に浸透するようになる。Next, in the second aspect of the invention, the rainwater that has flowed down the rain gutter connection pipe is stored in the rainwater reservoir of the rainwater receiver. Since the rainwater absorber is provided so as to project from the rainwater reservoir, the rainwater absorber is immersed in the rainwater accumulated in the rainwater reservoir and efficiently absorbs the rainwater. Thus, the rainwater absorbed by the rainwater absorber penetrates into the layer of backfilled earth that is in direct contact with the rainwater absorber in a state close to the natural world, as in the first invention. As described above, in the first and second inventions, the rainwater is once absorbed by the rainwater absorber, is absorbed and stored, and then permeates into the backfilled earth and sand layer in direct contact with the rainwater absorber.

たし、自然界の営みに近い状態で雨水が処理される。And the permeation of rainwater from the rainwater absorber to the above-mentioned backfilled soil layer permeates according to the change of the water content in the ground, which changes due to the evaporation of water from the ground surface. In the meantime, the state where rainwater is stored in the rainwater absorber is maintained. As a result, excess rainwater does not penetrate into the ground, and in the organic relationship between the rainwater absorber and the ground,
Rainwater is treated as if it fulfills the functions of water retention and water retention as if it were in the natural world such as forests.

雨水が処理される。With this configuration, the rainwater that has flowed down from the rain gutter 12 passes through the water-permeable holes 5 provided in the rainwater discharge pipe 4 during the flow-down process, is absorbed by the rainwater absorber 1 and is absorbed and stored. Part of the rainwater that has reached the filter layer 8 through the discharge pipe 4 is absorbed and stored in the rainwater absorber 1 because the rainwater absorber 1 is installed in the filter layer 8, and also in the filter layer 8. Is absorbed and stored in a water saturated state. On the other hand, the reduced amount of rainwater corresponding to the supersaturated water content of the filter layer 8 is discharged from the drain pipe 9. Since the rainwater absorbed by the rainwater absorber 1 is buried in the earth and sand layer 6 backfilled by the rainwater absorber 1 and both are in direct contact with each other, moisture from the surface of the backfilled earth and sand layer 6 is absorbed. Permeates according to the change in the water content of the backfilled earth and sand layer 6 that evaporates and changes, and the rainwater that permeates the backfilled earth and sand layer 6 penetrates deeper underground. Further, during fine weather, a large amount of water in the backfilled earth and sand layer 6 evaporates from the ground surface GL, and the water content of the backfilled earth and sand layer 6 decreases. Rainwater absorbed and stored in the rainwater absorber 1 permeates into the backfilled soil layer 6 and evaporates. In this way, the rainwater absorbed and stored in the rainwater absorber 1 in a state close to the nature is treated.

The point is that the rainwater is collected in the rainwater pool 10 and the rainwater absorber 1 absorbs the collected rainwater. Then, the overflowing rainwater is discharged from the drain pipe 9. This embodiment is effective when the amount of precipitation is relatively large, and the size of the rainwater receiver 7 and the volume of the rainwater absorber 1 are determined from the statistical amount of precipitation, and the depth of the rainwater receiver 7 is adjusted accordingly. The relationship between the height H 1 and the protrusion amount H 2 of the rainwater absorber 1 is determined.

減少する。As described above, in the first and second embodiments, the rainwater is once absorbed by the rainwater absorber 1, is absorbed and stored, and then permeates into the earth and sand layer 6 which is backfilled. Then, the permeation of rainwater from the rainwater absorber 1 into the backfilled earth and sand layer 6 causes a change in the water content of the backfilled earth and sand layer 6 which changes as the water evaporates from the surface of the backfilled earth and sand layer 6. Since the water permeates accordingly, the state in which rainwater is stored in the rainwater absorber 1 is maintained while the water content of the backfilled soil layer 6 is saturated. As a result, the rainwater is treated in a state close to that of the natural world, without excessive rainwater penetrating the backfilled soil layer 6.
Further, by reducing the amount of rainwater to the drain pipe 9 and making the flow gentle, the amount of rainwater collected in the sewer 17 is also reduced.

Since the stored rainwater is absorbed into the ground, it can be treated as if it were a natural activity, and
The amount of rainwater drained from the drainage pipe can be reduced. As a result, even if rainwater concentrates in the urban area or housing complex, the flow rate of the sewer will be reduced and urban flood damage will be prevented.
In addition, the rainwater absorbed and stored in the rainwater absorber should be absorbed according to the changing water content in the ground by evaporating from the ground surface, and the absorbed rainwater should be further infiltrated into the underground to perform a treatment similar to the natural activity. Since the ground surface is covered with asphalt, the decrease of urban groundwater caused by the lack of underground infiltration of rainwater is prevented, which prevents ground subsidence. Have an effect.
