A metal waste receiving colander 12 is provided inside the rainwater mass 2. The waste receiving colander 12 has an edge 12a and a handle 12b. The garbage-receiving colander 12 has an edge 12 a mounted on a constricted portion 15 of the mass body 6.

Next, the installation of the rainwater mass system 1 will be described. As shown in FIG.
A plurality of rainwater cells 2 are buried in 1. Rainwater trough 2 has lid 9
Is buried at a depth where it is exposed to the ground. A joint (not shown) is provided at the upper water pipe joint 16 of some of the rainwater masses 2 at the same height as the upper water pipe joint 18, and the joint is provided on the roof of the building 22. A rainwater introduction pipe 22b extending from the gutter 22a is connected.

Each buried rainwater mass 2 is connected via a socket 3 at the underground 21 using each of the water pipes 4 and 5. The end of the upper water pipe 4 is connected to a drain 23 outside the premises.
The lower water pipe 5 is connected in a ring shape through a plurality of rainwater masses 2. In order to improve drainage, crushed stones 24 are spread around the lower water pipe 5.

Next, the operation of the rainwater mass system 1 configured as described above will be described. The rainwater collected by the gutter 22a provided on the roof of the building 22 passes through the rainwater inlet pipe 22b to the upper water pipe joint 16 of the rainwater mass 2.
Flow into The rainwater that has flowed into the upper water pipe joint 16 flows down to the lower water pipe joint 17 through the waste receiving colander 12 provided in the constriction 15. At this time, trash such as pebbles and tree leaves mixed in the rainwater is removed by the trash receiving colander 12. The garbage received by the garbage receiving colander 12 can be easily removed by opening the lid 9 of the rainwater trough 2 and removing the garbage receiving colander 12.

The rainwater that has flowed down to the lower water pipe joint 17 is supplied to the bottom hole 10 a of the bottom plate 10 attached to the lower end port 14.
From the ground. In addition, it penetrates into the underground 21 from the outlet 19 to which the wire mesh 11 is attached.

Further, the rainwater accumulates in the lower water pipe joint 17 and flows into the lower water pipe 5. The rainwater flowing into the lower water pipe 5 penetrates into the underground 21 from the drain hole 20. Furthermore, the rainwater flows into another rainwater mass 2 connected by the lower water pipe 5, and the bottom hole 10a of the other rainwater mass 2
Then, the water is permeated into the underground 21 from the drain hole 20 of the lower water pipe 5. In this way, the rainwater permeates the underground 21 throughout the site.

When the amount of rainwater is large, the level of the rainwater in the lower water pipe 5 rises, and is discharged from the drain hole 20b or the drain hole 20c higher than the drain hole 20a, and penetrates into the underground 21. Is done. Drainage hole 2 located high
It is provided at a position closer to the rainwater mass 2 by approximately 0b and 20c. As described above, the infiltration of the rainwater from the lower water pipe 5 into the underground 21 is performed sequentially from a position away from the main body 6.

When the water level reaches the upper water pipe joint 16 due to the large amount of rain water, the rain water flows into the upper water pipe 4, and from the upper water pipe 4 to the drain 23 through the rain water mass 2. Drained.

As described above, according to the present embodiment, the following operations and effects can be obtained. The provision of the lower water pipe 5 having the drain hole 20 penetrated through the rainwater mass 2 allows the rainwater to surely penetrate into the underground 21 even if the amount of rainwater is somewhat large. Therefore, it is effective for groundwater preservation, and can reduce the possibility that rainwater overflows from the drain.

Since the drain hole 20 farther from the rainwater mass 2 is located at a lower position, the rainwater
It is infiltrated in order from farther away. Therefore, the permeation area of the rainwater is widened, and the permeation can be reliably performed.

The above embodiment may be modified as follows, and the same operation and effect can be obtained in such a case. A plurality of types of masses having the outlet 19 of the mass body 6 opened at one to three locations are prepared.

In this way, a branching mode of the lower water pipe 5 of the rainwater drainage system 1 can be realized. A basket with small holes is provided in the constricted portion 15 of the mass body 6 instead of the waste receiving colander 12.

In this way, it is possible to prevent the small drainage that cannot be received by the waste receiving colander 12 from flowing into the lower water pipe 5 to block the drain hole 20. In addition, since the basket can be attached and detached, the accumulated dust can be easily cleaned.

A cap for sealing the upper water pipe connection port 18 can be connected to the upper water pipe joint 16. By doing so, the degree of freedom in disposing the upper water pipe 4 can be improved.
