By using such a water storage structure 10, for example, when it rains on the water storage structure 10, rain water can be temporarily stored. Specifically, when rain falls on the water storage structure 10, the rainwater comes in contact with the water collection member 2a, and the rainwater is collected toward the water collection through hole 2c by the inclination of the water collection inclined portion 2d. The collected rain water flows into the solid-liquid separation main body 4b of the solid-liquid separation member 4a and permeates the solid-liquid separation through hole 4d to separate the solid matter, and the first water storage member 3a Flow into storage space R1.

  Here, when the amount of water flowing into the first water storage space R1 is small (for example, when the amount of precipitation is small), the water flowing into the first water storage space R1 is, as shown in FIG. Through the first bottom 3c and drained from the space to the outside of the water storage structure 10 through the water drainage path X. On the other hand, when the amount of water flowing into the first water storage space R1 is large (for example, when the amount of precipitation is large), part of the water flowing into the first water storage space R1 is from the water drainage path X as described above While being discharged, the remainder is stored in the first water storage space R1. Thereby, the water level of the first water storage space R1 rises, and when the water level reaches the lower end portion of the first side wall through hole 3d, the water of the first water storage space R1 passes through the first side wall through hole 3d and the second It flows out into the water storage member 6a (second water storage space R2).

  The water which flowed out from the first water storage space R1 to the second water storage space R2 is stored in the second water storage space R2. Thereby, the water level of 2nd water storage space R2 rises. Then, when the water level reaches the lower end portion of the first side wall through hole 3d, the outflow of water from the first water storage space R1 to the second water storage space R2 substantially stops, and the water level of the first water storage space R1 The water level of the second water storage space R2 rises at the same height position. Thereafter, even when the inflow of water into the first water storage space R1 is stopped (when the amount of precipitation is zero), the water drainage by the water drainage path X is continued. Thereby, the water in the first water storage space R1 is discharged from the first water discharge part 3e through the water drainage path X to the outside of the water storage part 10a, and the water in the second water storage space R2 penetrates the first side wall It flows into the first water storage space R1 through the hole 3d, and is discharged from the first water discharge portion 3e to the outside of the water storage portion 10a through the water drainage path X. Furthermore, even when the water level in the second water storage space R2 falls below the lower end of the first side wall through hole 3d, the water in the second water storage space R2 flows into the first water storage space R1 through the second drainage portion 6d. The water is discharged from the first drainage portion 3e through the water drainage path X to the outside of the water storage portion 10a. Thereby, the water of the first water storage space R1 and the water of the second water storage space R2 are substantially discharged.

  As described above, the water storage structure according to the present invention and the water storage structure aggregate form are capable of efficiently discharging water from the water storage structure even when the amount of water supplied to the water storage structure is small. As well as being able to store more water if the amount of water supplied is large.

  That is, the area of the second bottom 6c is configured to be larger than the area of the first bottom 3c. For this reason, even when the amount of water collected by the water collection member 2a is relatively small (for example, when the amount of precipitation is small), water can be efficiently discharged from the water storage portion 10a.

  Specifically, if the amount of water collected by the water collection unit 2a is relatively small (for example, when the amount of precipitation is small), if the water flows into the second water storage space R2, the second bottom portion 6c Because the area is relatively large, the water will spread widely. For this reason, water can not be discharged efficiently from the second water storage member 6a.

  On the other hand, since the water collected by the water collection member 2a flows into the first water storage space R1, the area of the first bottom 3c is relatively narrow even if the amount of water flowing in is relatively small, Water does not spread widely. Thereby, discharge of the water from the 1st water storage member 3a can be performed efficiently. That is, the water collected by the water collecting member 2a is stored in the first water storage space R1, and the water is discharged from the water storage structure 10 even if the amount of water collected by the water collecting member 2a is small. Can be done efficiently.

  Further, the velocity of the water discharged from the first drainage portion 3e is configured to be slower than the velocity at which the water in the first water storage space R1 flows out to the second water storage space R2 through the first side wall through hole 3d. The speed of the water discharged from the second drainage portion 6d is configured to be slower than the speed of the water flowing out of the first water storage space R1 into the second water storage space R2 through the first side wall through hole 3d. Be done.

  Accordingly, when the amount of water collected by the water collection member 2a is relatively large (for example, when the amount of precipitation is large), the water is stored in the first water storage space R1 and the water level rises. Then, when the water level of the first water storage space R1 exceeds the lower end portion of the first side wall through hole 3d, water is discharged from the first water storage space R1 to the second water storage space R2 through the first side wall through hole 3d. The water is stored in the second water storage space R2. As a result, water can be stored in the first water storage space R1 and the second water storage space R2, and thus more water can be stored than in the case where water is stored only in the first water storage space R1 or only in the second water storage space R2. Water can be stored.

  Further, by forming the first side wall through hole 3d to extend in the vertical direction, even when the water level of the first water storage space R1 rises beyond the lower end portion of the first side wall through hole 3d, the first side wall Water can be efficiently discharged from the first water storage space R1 to the second water storage space R2 through the through holes 3d.

  In addition, by providing a solid-liquid separation unit as described above, it is possible to prevent unintended intrusion of solid matter (for example, fallen leaves, stones, etc.) from the sidewall opening into the first water storage space R1. it can.

  In addition, the first water storage member 3a is configured to be removable with respect to the second water storage member 6a. Thereby, since the 1st water storage member 3a can be removed from the 2nd water storage member 6a, the operation | work which wash | cleans and replaces the 1st water storage member 3a can be performed easily.
