  As shown in FIG. 11, a handle 63 is provided on the upper end surface of the groove filling plate 23. The shape of the handle 63 is not particularly limited, but here, the handle 63 extends upward from the upper end surface of the groove filling plate 23 and has a space in the center. The handle 63 may be integrated with the groove filling plate 23 or may be a separate body.

  Next, the storage tank 70 will be described. As shown in FIG. 3, the storage tank 70 is a tank that stores sewage discharged from the drainage facility 5. The storage tank 70 is constituted by a tank and has a space sealed inside. A drain port 71 is formed in the upper part of the side surface of the storage tank 70. The drain outlet 71 is connected to the downstream end of the second outlet pipe 13, and the second outlet 34 of the drain 20 is connected via the second outlet pipe 13.

  A cylinder 78 protrudes from the upper surface of the storage tank 70 in the vertical direction. The cylinder 78 is provided on the upper surface of the storage tank 70 so that the upper end is substantially the same height as the ground. An operator can maintain and inspect the inside of the septic tank 70 through the cylinder 78. Note that the upper portion of the cylinder 78 is closed by a lid 79 in a normal state.

  Next, a method for using the drainage system 1A and the drainage basin 20 according to the present embodiment will be described. The drainage system 1A normally discharges sewage flowing out from the drainage facility 5 to the sewage main 15 and when a disaster such as an earthquake or a tsunami occurs and the first spillway 12 or the sewage main 15 is damaged, It is used so that the flow path of the drainage basin 20 is switched to discharge the sewage discharged from the drainage facility 5 to the storage tank 70. In the following description, a normal usage mode is referred to as a normal mode, and a disaster usage mode is referred to as a disaster mode.

  As shown in FIG. 4, in the normal mode, the sewage flowing into the main body 21 from the inlet 32 of the drain 20 flows out from the first outlet 33 and is discharged to the sewage main pipe 15. Two partition plates 22 and a groove filling plate 23 are arranged. Specifically, the one partition plate 22 is attached to a second groove portion 42 (see FIG. 5) provided in the second outflow side invert 34a. The other partition plate 22 is attached to a third groove portion 43 (see FIG. 5) provided in the third outflow side invert 35a. Further, the groove filling plate 23 is attached to the first groove portion 41 (see FIG. 5) provided in the first outflow side invert 33a.

  As shown in FIG. 1, in the normal mode, the sewage flowing out from the drainage facility 5 flows into the main body 21 from the inlet 32 of the drainage basin 20 after flowing through the inflow conduit 11. As shown in FIG. 4, the sewage that has flowed into the main body 21 passes through the inflow side invert 32a. Thereafter, the sewage passes through the opening 62 (see FIG. 11) of the groove filling plate 23, then passes through the first outflow side invert 33 a, and then flows out of the main body 21 from the first outlet 33. At this time, the partition plate 22 is mounted in the second groove portion 42 of the second outflow side invert 34a. Therefore, the sewage does not flow to the second outlet 34 by the partition plate 22. Similarly, the partition plate 22 is mounted in the third groove portion 43 of the third outflow side invert 35a. Therefore, the sewage does not flow to the third outlet 35 due to the partition plate 22. A groove filling plate 23 is attached to the first groove 41 of the first outflow side invert 33a. This prevents foreign matter contained in the sewage from being caught in the first groove 41. As shown in FIG. 1, the sewage flowing out from the first outlet 33 flows through the first outlet pipe 12 and is discharged to the sewage main pipe 15. The sewage discharged to the sewage main 15 is guided to a sewage treatment plant or the like and purified.

  In the disaster mode, the flow path of the sewage is switched by the drainage basin 20 so that the sewage flowing into the main body 21 from the inlet 32 flows out from the second outlet 34 and is discharged to the storage tank 70. The arrangement of the two partition plates 22 and the groove filling plate 23 is changed. FIG. 15 is a diagram illustrating an arrangement state of the partition plate 22 and the groove filling plate 23 in the disaster mode. Specifically, as shown in FIG. 4, the operator, as shown in FIG. 4, has the partition plate 22 attached to the second groove portion 42 (see FIG. 5) of the second outflow side invert 34a and the first outflow side invert 33a. The groove filling plate 23 attached to the one groove portion 41 (see FIG. 5) is removed. Next, as shown in FIG. 15, the operator attaches the groove filling plate 23 to the second groove portion 42 and attaches the partition plate 22 to the first groove portion 41. In addition, the partition plate 22 is attached to the third groove portion 43.

  As shown in FIG. 1, in the disaster mode, the sewage flowing out from the drainage facility 5 flows into the main body 21 from the inlet 32 of the drainage basin 20 after flowing through the first outflow pipe 11. As shown in FIG. 15, the sewage that has flowed into the main body 21 passes through the inflow side invert 32a. Thereafter, the sewage passes through the opening 62 (see FIG. 11) of the groove filling plate 23, then passes through the second outflow side invert 34a, and then flows out of the main body 21 from the second outflow port 34. At this time, the partition plate 22 is attached to the first groove portion 41 and the third groove portion 43, respectively, so that sewage does not flow to the first outlet port 33 and the third outlet port 35. The groove filling plate 23 is attached to the second groove portion 42 of the second outflow side invert 34a. This prevents foreign matter contained in the sewage from being caught in the second groove portion 42. As shown in FIG. 1, the sewage flowing out from the second outlet 34 is discharged to the storage tank 70 through the second outlet pipe 13 and stored. The sewage stored in the storage tank 70 is sucked up by, for example, a suction pump (not shown). In this case, the operator removes the lid 79 that closes the upper portion of the cylinder 78 provided on the upper surface of the storage tank 70, and inserts the suction pump into the storage tank 70 through the cylinder 78. Then, the sewage stored in the storage tank 70 is sucked up by the suction pump.

  As described above, in this embodiment, as shown in FIG. 4, in the normal mode, the sewage that has flowed into the main body 21 from the inflow port 32 flows out from the first outflow port 33. 22 are mounted in the second groove portion 42 (see FIG. 5) and the third groove portion 43 (see FIG. 5), respectively, and the groove filling plate 23 is mounted in the first groove portion 41 (see FIG. 5). The sewage flowing in from the inflow port 32 does not flow to the second outflow port 34 and the third outflow port 35 by the partition plate 22, but passes through the inflow side invert 32a and the first outflow side invert 33a to the first outflow port 33. Flowing. At this time, since the first groove portion 41 is filled with the groove filling plate 23, it is possible to prevent the foreign matter contained in the sewage from clogging the first groove portion 41. Thereafter, as shown in FIG. 1, the sewage that has flowed into the main body 21 from the first outlet 33 is discharged to the sewage main pipe 15 through the first outlet pipe 12. Therefore, in the normal mode, the sewage flowing out from the drainage facility 5 can be discharged to the sewage main pipe 15.

  On the other hand, in the disaster mode, the flow path of the sewage is changed by the drainage basin 20 so that the sewage flowing into the main body 21 from the inlet 32 flows out from the second outlet 34. At this time, as shown in FIG. 4, the groove filling plate 23 attached to the first groove portion 41 and the partition plate 22 attached to the second groove portion 42 are removed. Then, as shown in FIG. 15, the partition plate 22 is attached to the first groove portion 41, and the groove filling plate 23 is attached to the second groove portion 42. At this time, the first groove portion 41 and the second groove portion 42 are not clogged with foreign matters contained in the sewage, so that the partition plate 22 and the groove filling plate 23 can be easily attached. Therefore, the flow path of sewage can be switched smoothly.

  In the disaster mode, the sewage flowing into the main body 21 from the inflow port 32 does not flow to the first outflow port 33 and the third outflow port 35, but passes through the inflow side invert 32a and the second outflow side invert 34a. 2 flows to the outlet 34. At this time, since the second groove portion 42 provided in the second outflow side invert 34a is filled with the groove filling plate 23, it is possible to prevent the foreign matter contained in the sewage from being clogged in the second groove portion 42. Thereafter, as shown in FIG. 1, the sewage flowing out from the second outlet 34 is discharged to the storage tank 70 through the second outlet pipe 13. Therefore, in the disaster mode, the sewage flowing out from the drainage facility 5 can be discharged to the storage tank 70.

  In the present embodiment, as shown in FIG. 5, the first groove part 41, the second groove part 42, and the third groove part 43 are formed of a flexible member. Accordingly, as shown in FIG. 10, the partition plate 22 is attached in close contact with the first groove portion 41, the second groove portion 42, and the third groove portion 43. Therefore, when the partition plate 22 is attached to the first groove portion 41, it is possible to further prevent sewage from flowing between the partition plate 22 and the first groove portion 41. Similarly, when the partition plate 22 is attached to the second groove portion 42 and when the third groove portion 43 is attached, the space between the second groove portion 42 and the partition plate 22, and between the third groove portion 43 and the partition plate 22.

The upstream end of the third outlet pipe 14 is connected to the third outlet 35 of the drain 20. The downstream end of the third outflow conduit 14 is connected to a storage tank 70 that stores sewage. A pipe forming a part of the drainage pipe 10 is not connected to the second outlet 34 of the drainage basin 20. Here, the second outlet 34 is not used. In the present embodiment, as in the first embodiment, the second outlet 34 and the third outlet 35 are provided in the main body 21 and are disposed at opposing positions.

  Next, a method for using the drainage system 1B according to the present embodiment will be described. Since the normal mode is the same as that of the first embodiment, detailed description thereof is omitted. In the disaster mode, the flow path of the sewage is switched by the drainage basin 20 so that the sewage flowing into the main body 21 from the inlet 32 flows out from the third outlet 35 and is discharged to the storage tank 70. The arrangement of the two partition plates 22 and the groove filling plate 23 is changed. Specifically, as shown in FIG. 4, the operator can use the partition plate 22 attached to the third groove 43 (see FIG. 5) of the third outflow side invert 35 a and the first outflow side invert 33 a of the first outflow side invert 33 a.

The sewage flowing into the main body 21 passes through the inflow side invert 32a. Thereafter, the sewage passes through the opening 62 (see FIG. 11) of the groove filling plate 23, then passes through the third outflow side invert 35a, and flows out of the main body 21 from the third outflow port 35. At this time, since the partition plate 22 is attached to each of the first groove portion 41 and the second groove portion 42, the sewage does not flow to the first outlet port 33 and the second outlet port 34. A groove filling plate 23 is attached to the third groove 43 of the third outflow side invert 35a. This prevents foreign matters contained in the sewage from being caught in the third groove 43. The sewage flowing out from the third outlet 35 is discharged to the storage tank 70 through the third outlet pipe 14 and stored.

  In the present embodiment, if an object such as another pipe line is disposed on the second outlet 34 side and a pipe that forms a part of the drain pipe 10 cannot be connected to the second outlet 34, Even when the storage tank 70 cannot be disposed on the second outlet 34 side, the third outlet pipe in which the storage tank 70 is disposed on the third outlet 35 side and the storage tank 70 is connected to the third outlet 35. The path 14 can be connected. Therefore, at the time of a disaster, the flow path of the sewage can be switched, and the sewage flowing into the main body 21 from the inflow port 32 can be further discharged out of the main body 21 from the third outflow port 35.
