Description

The present invention relates to piping equipment for temporary toilets.

When a disaster such as an earthquake occurs, many people may evacuate to an evacuation site such as a public facility and live in the evacuation site. At this time, depending on the situation of the disaster, the water supply facility could not be used and the toilet at the evacuation site could not be used.

Therefore, a plumbing fixture has been proposed so that a temporary toilet can be installed. For example, the piping equipment for temporary toilets described in Patent Document 1 includes a drainage pipe buried in the ground and a vertical pipe having one end connectable to a toilet bowl of the temporary toilet and the other end connected to the drainage pipe. It is equipped with an outflow pipe that connects the drainage pipe and the existing sewage main, and a water storage gate that is arranged between the drainage pipe and the outflow pipe and can open and close the end of the drainage pipe. The water storage gate is configured to overflow to the outflow pipe when the sewage stored in the drainage pipe rises above a predetermined water level.

In this temporary toilet piping facility, the water storage gate is in a state where the end of the drain pipe is closed in the event of a disaster. When using a temporary toilet, sewage is stored in the drain pipe, and when the sewage stored in the drain pipe rises above a predetermined water level, the sewage overflows into the outflow pipe. Further, by opening the end of the drain pipe by the water storage gate, the sewage stored in the drain pipe is discharged to the sewage main through the outflow pipe.

Japanese Patent No. 4104197

By the way, in the event of a disaster such as an earthquake, the sewage main may be damaged. If the sewage main is damaged, the sewage discharged from the drain pipe to the sewage main may leak to the outside from the damaged part of the sewage main. Therefore, in order to suppress leakage of sewage to the outside, it is conceivable to keep closing the end of the drainage pipe by, for example, a water storage gate. However, there is a limit to the amount of sewage that can be stored in the drain pipe, and if the limit is exceeded, the temporary toilet cannot be used. In the invention disclosed in Patent Document 1, in order to secure the amount of sewage that can be stored in the drainage pipe, for example, it is conceivable to modify the drainage pipe so that the diameter is relatively large. However, when the diameter of the drainage pipe is relatively large, the construction cost and the labor of the operator increase, and it may be difficult to secure the construction space of the drainage pipe having a large diameter.

The present invention has been made in view of this point, and an object of the present invention is to lengthen a temporary toilet without leaking sewage discharged from the temporary toilet to the outside even if the sewage main is damaged in the event of a disaster. It is to provide piping equipment for temporary toilets that can be used continuously.

The inventor of the present application examined a means for continuing to use a temporary toilet for a long time in the event of a disaster. As a result, the inventor of the present application paid attention to the rainwater tank used for storing rainwater at normal times other than disasters. Then, when the sewage main is damaged, the inventor of the present application discharges the sewage discharged from the temporary toilet to the sewage storage space, and the amount of sewage stored in the sewage storage space reaches a predetermined amount. In that case, it was found that the temporary toilet could be used for a longer period of time by discharging the sewage to the rainwater tank.

That is, the temporary toilet piping equipment according to the present invention includes a main pipeline, a standing pipe, a flow path switching means, a sewage storage space, a gate, and a rainwater tank. The main pipeline includes a first pipeline, a second pipeline arranged on the downstream side of the first pipeline, and a third pipeline arranged on the downstream side of the second pipeline. It has a fourth pipeline arranged on the downstream side of the third pipeline, and at least sewage can flow through it. One end of the vertical pipe is connected to the first pipe, and a toilet bowl of a temporary toilet can be attached to the other end. The flow path switching means is connected to the downstream end of the first pipeline and the upstream end of the second pipeline. The sewage storage space portion has an inflow port to which the downstream end of the second pipeline is connected and an outflow port to which the upstream end of the third pipeline is connected, and sewage is stored. The gate includes a gate inlet to which the downstream end of the third pipeline is connected and a gate main body to which a gate outlet to which the upstream end of the fourth pipeline is connected is formed and has a space inside. It has a closing means capable of closing at least one of the third pipeline and the fourth pipeline. The rainwater tank is formed with a first inflow port to which the flow path switching means is connected and a second inflow port to which the rainwater supply source is connected, and at least rainwater can be stored. The flow path switching means can be switched between a first state in which sewage flows from the first pipe line to the second pipe line and a second state in which sewage flows from the first pipe line to the rainwater tank. be.

According to the piping equipment for temporary toilets according to the present invention, when a temporary toilet is installed in the event of a disaster such as an earthquake, the sewage discharged from the temporary toilet is discharged to the sewage main through the main pipeline. If the sewage main is damaged, the gate closing member closes at least one of the third and fourth pipes. As a result, the sewage discharged from the temporary toilet can be stored in the sewage storage space without being discharged to the sewage main. Therefore, it is possible to prevent sewage from leaking to the outside from the damaged portion of the sewage main. When the amount of sewage stored in the sewage storage space reaches a predetermined amount, the flow path of the sewage is switched by the flow path switching means. As a result, the sewage discharged from the temporary toilet can be stored in the rainwater tank, and it is possible to prevent the sewage from overflowing from the sewage storage space. Therefore, if the sewage main is damaged during a disaster, the temporary toilet can be continued to be used even if the amount of sewage discharged from the temporary toilet exceeds the storage limit of the sewage storage space. Therefore, the sewage discharged from the temporary toilet does not leak to the outside, and the temporary toilet can be used continuously for a long time. In addition, the rainwater tank is used as a tank for storing rainwater during normal times other than disasters. Therefore, the rainwater tank that is normally used can be used as a tank for urgently discharging sewage in the event of a disaster, so that it is not necessary to use a dedicated tank for a disaster. Therefore, the construction cost can be reduced and the construction space can be secured.

According to a preferred embodiment of the present invention, the flow path switching means includes an inspection port that opens upward, an inflow port to which the downstream end of the first pipeline is connected, and an upstream end of the second pipeline. A main body having a first outlet to which the rainwater tank is connected and a second outlet to which the rainwater tank is connected, and a main body provided in the main body, from the inlet to the second outlet. The first switching position that communicates the inlet and the first outlet so that sewage does not flow, and the inlet that prevents sewage from flowing from the inlet to the first outlet. It is provided with a switching means capable of changing the position between the second switching position and the second switching position for communicating with the second outlet.

According to the above aspect, it has a flow path switching function. The flow path can be easily switched by simply changing the position of the switching means. By the way, foreign matter may flow in the main pipeline. In addition, after many years of use, deposits may accumulate on the main pipeline. Therefore, foreign matter or deposits may impair the flow path switching function. However, since it is equipped with an inspection port, maintenance is easy. Therefore, when foreign matter is clogged or deposits are accumulated inside, the foreign matter or deposits can be easily removed from the inspection port. Therefore, in the event of a disaster, the flow path switching function can be sufficiently secured, and it becomes easy to avoid a situation in which the flow path cannot be switched.

According to another preferred aspect of the present invention, the rainwater tank is formed with a suction port. The temporary toilet piping equipment is provided with a suction pipeline having one end connected to the suction port and the other end connected to a portion of the first pipeline upstream of the standing pipe and the suction pipeline. It is equipped with a suction pump.

According to the above aspect, the rainwater stored in the rainwater tank can be supplied to the first pipeline through the suction pipeline by a suction pump. Therefore, the rainwater stored in the rainwater tank can be used to discharge the excrement discharged from the temporary toilet to any of the sewage main, the sewage storage space, and the rainwater tank.

According to another preferred embodiment of the present invention, the rainwater tank is provided with a closing means capable of closing the second inflow port.

According to the above aspect, when the flow path of the sewage is switched and the sewage flows into the rainwater tank, the second inflow port is closed by the closing means, so that the odor of the sewage is released to the outside through the second inflow port. Leakage can be suppressed. Further, by closing the second inflow port by the closing means, it is possible to prevent the sewage from flowing back to the rainwater supply source through the second inflow port.

According to another preferred aspect of the present invention, the first pipeline includes a first upstream pipeline to which the vertical pipe is connected and a first downstream pipeline arranged downstream of the first upstream pipeline. It has a pipeline. In the temporary toilet piping facility, the other flow path switching means connected to the downstream end of the first upstream pipeline and the upstream end of the first downstream pipeline is connected to the other flow path switching means. It comprises another first inflow port and another rainwater tank in which another second inflow port connected to another rainwater source is formed and at least stores rainwater. The other flow path switching means has another first state of flowing sewage from the first upstream pipe to the first downstream pipe and flowing sewage from the first upstream pipe to the other rainwater tank. It is possible to switch to another second state.

According to the above aspect, when the flow path of sewage is switched by the flow path switching means in the event of a disaster, the sewage discharged from the temporary toilet can be stored in the rainwater tank. If the amount of sewage stored in the rainwater tank reaches a predetermined amount, the flow path of the sewage is further switched by another flow path switching means. At this time, the sewage discharged from the temporary toilet can be stored in another rainwater tank. Therefore, if the sewage main is damaged during a disaster, the sewage discharged from the temporary toilet is discharged to any of the sewage storage space, the rainwater tank, and other rainwater tanks, so that the temporary toilet can be used. ..

According to the present invention, even if the sewage main is damaged in the event of a disaster, the sewage discharged from the temporary toilet does not leak to the outside, and the temporary toilet can be used continuously for a long time. Can be provided.

The tank outlet 64 is formed in the sewage tank 60 so as to face the tank inlet 63 in a plan view. The tank outlet 64 is arranged at a position lower than the tank inlet 63. However, the positional relationship between the tank inlet 63 and the tank outlet 64 is not particularly limited. For example, the tank outlet 64 may not face the tank inlet 63 in a plan view, but may be formed at a position deviated from the facing position.

As shown in FIG. 3, the gate 70 blocks the flow of sewage into the fourth pipe line 14 and the sewage main pipe 8. For example, when the sewage main 8 is damaged, the flow of sewage can be regulated by the gate 70 to prevent the sewage from leaking from the damaged portion of the sewage main 8. As shown in FIG. 2, the gate 70 is arranged between the third pipe line 13 and the fourth pipe line 14. The configuration of the gate 70 is not particularly limited. FIG. 9 is a front sectional view of the gate 70. In this embodiment, as shown in FIG. 9, the gate 70 includes a gate body 71 and a closing member 72.

The gate body 71 has a space inside. An inspection port 75 that opens upward is formed in the upper part of the gate body 71. A lid 76 is detachably provided on the inspection port 75. A gate inlet 77 and a gate outlet 78 are formed on the side surface of the gate body 71. The downstream end of the third pipeline 13 is connected to the gate inflow port 77. The upstream end of the fourth pipeline 14 is connected to the gate outlet 78. In a plan view, the gate inlet 77 and the gate outlet 78 face each other. The lower end of the gate inlet 77 is arranged at a position higher than the lower end of the gate outlet 78. However, the lower end of the gate inlet 77 and the lower end of the gate outlet 78 may be at the same height.

In the present embodiment, the closing member 72 closes the fourth pipeline 14. Here, the closing member 72 closes the fourth pipeline 14 by closing the gate outlet 78. The closing member 72 is detachably provided at the gate outlet 78 in the gate body 71. The closing member 72 may close the gate inflow port 77, or may be detachably provided at the gate inflow port 77. Although not shown, the gate body 71 has a state in which the closing member 72 closes the gate outlet 78 and a state in which the closing member 72 opens the gate outlet 78 by being operated by an operator. A mechanism that can change the position may be provided. The closing member 72 may close the third pipeline 13. In this case, the closing member 72 may be detachably provided at the gate inflow port 77, and may be configured to close the third pipeline 13 by closing the gate inflow port 77.

As shown in FIG. 1, the rainwater tank 80 is a tank capable of storing at least rainwater. Here, rainwater is stored in the rainwater tank 80 during a normal time other than a disaster. Therefore, the rainwater tank 80 is a tank that is used even in a normal state. At the time of a disaster, sewage may be stored in the rainwater tank 80 in addition to rainwater. In the present embodiment, when the flow path of sewage is switched by 30 in the event of a disaster, sewage may be stored in the rainwater tank 80. The rainwater tank 80 is connected to the second outlet 44 of 30 more. Here, one end of the sub-pipeline 18 is connected to the second outlet 44. The other end of the sub-pipeline 18 is connected to the rainwater tank 80.

The configuration of the rainwater tank 80 is not particularly limited. FIG. 10 is a front sectional view of the rainwater tank 80. As shown in FIG. 10, the rainwater tank 80 is formed with an inspection port 81 that opens upward. The operator can inspect the inside of the rainwater tank 80 through the inspection port 81. When the inspection port 81 is not in use, the inspection port 81 is provided with a lid 82.

The rainwater tank 80 is formed with a first inflow port 83 and a second inflow port 84. The other end of the sub-pipeline 18 is connected to the first inflow port 83, and the second outflow port 44 of 30 is connected to the first inflow port 83 via the sub-pipeline 18. A gutter 9 is connected to the second inflow port 84. In the present embodiment, one end of the rainwater pipeline 19 is connected to the second inflow port 84. As shown in FIG. 3, a gutter 9 is connected to the other end of the rainwater pipeline 19. The gutter 9 is an example of the "rainwater supply source" of the present invention. The "rainwater supply source" according to the present invention refers to a member in which rainwater discharged to the rainwater tank 80 collects. The rainwater collected at the rainwater supply source is supplied to the rainwater tank 80 through the rainwater pipeline 10. Here, rainwater flows into the rainwater tank 80 through the gutter 9. The rainwater supply source of the present invention is not limited to the gutter 9. For example, instead of the gutter 9, a gutter may be connected to the other end of the rainwater conduit 19. Further, instead of the gutter 9, a so-called rainwater basin may be connected to the other end of the rainwater pipeline 19. In this case, a gutter or stormwater is an example of the "rainwater source" of the present invention. In the present embodiment, the second inflow port 84 serves as a so-called overflow port. For example, when the water level of the rainwater in the rainwater tank 80 reaches the height of the lower end of the second inflow port 84 or higher, the rainwater may flow back from the second inflow port 84 to the rainwater conduit 19.

In the present embodiment, as shown in FIG. 10, the center P21 of the first inflow port 83 is located at the upper portion when the rainwater tank 80 is divided into two equal parts in the vertical direction. Here, the first inflow port 83 is formed in an upper portion of the side surface of the rainwater tank 80. However, the first inflow port 83 may be formed on the upper surface of the rainwater tank 80. In the present embodiment, the center P22 of the second inflow port 84 is located at the upper portion of the rainwater tank 80. Here, the second inflow port 84 is formed at an upper portion of the side surface of the rainwater tank 80. However, the second inflow port 84 may be formed on the upper surface of the rainwater tank 80. The position of the height of the lower end of the second inflow port 84 is the same as the position of the height of the lower end of the first inflow port 83. However, the position of the lower end of the second inflow port 84 may be higher or lower than the position of the lower end of the first inflow port 83.

Further, in the present embodiment, the rainwater tank 80 is formed with a suction port 85. The suction port 85 is connected to the suction pipe line 90. Here, the center P23 of the suction port 85 is located at a lower portion when the rainwater tank 80 is divided into two equal parts in the vertical direction. The suction port 85 is formed in a portion below the side surface of the rainwater tank 80, however, the suction port 85 may be formed in the bottom surface of the rainwater tank 80. The suction port 85 is arranged at a position lower than the first inflow port 83 and at a position lower than the second inflow port 84.

The rainwater tank 80 may include a closing member 86 capable of closing the second inflow port 84. The closing member 86 is detachably provided at the second inflow port 84 in the rainwater tank 80. When sewage flows into the rainwater tank 80, the closing member 86 closes the second inflow port 84, so that the odor of the sewage can be suppressed from leaking to the outside through the second inflow port 84. Further, by closing the second inflow port 84 by the closing member 86, it is possible to suppress the flow of sewage into the gutter 9 through the second inflow port 84. Although not shown, the rainwater tank 80 is in a state where the closing member 86 closes the second inflow port 84 and the closing member 86 opens the second inflow port 84 by being operated by an operator. A mechanism that can change the position may be provided depending on the state of the gutter. Further, a closing member similar to the closing member 86 may be provided so that the suction port 85 can be closed and detachable. The closing member 86 may be a plug inserted into the second inflow port 84. Further, the closing member 86 may close the mouth (not shown) to which the rainwater conduit 19 of the gutter 9 is connected. For example, the closing member 86 may be a plug inserted into the mouth to which the rainwater conduit 19 of the gutter 9 is connected. In the present embodiment, the closing member 86 is an example of the "closing means" of the present invention.

As shown in FIG. 3, the suction pipe 90 connects the rainwater tank 80 and the first pipe 11 of the main pipe 10. One end of the suction pipe line 90 is connected to the suction port 85 of the rainwater tank 80. The other end of the suction pipe line 90 is connected to a portion upstream of the standing pipe 15 of the first pipe line 11.

The suction pump 95 sucks the rainwater stored in the rainwater tank 80. The suction pump 95 is provided in the middle of the suction pipe line 90. By operating the suction pump 95, the rainwater in the rainwater tank 80 is supplied to the upstream end of the first pipe line 11 through the suction pipe line 90. Therefore, the rainwater in the rainwater tank 80 can be used to flush the excrement excreted from the temporary toilet 3 to the downstream side. The type of suction pump 95 is not particularly limited. For example, the suction pump 95 may suck rainwater in the rainwater tank 80 by driving a motor (not shown). The motor may be driven by, for example, a battery. Further, the suction pump 95 may be a manual pump that sucks rainwater in the rainwater tank 80 by being manually operated by an operator.

The configuration of the temporary toilet piping facility 1A according to the present embodiment has been described above. Next, a method of using the temporary toilet piping facility 1A will be described. As shown in FIG. 1, the temporary toilet 3 is not normally installed in the temporary toilet piping facility 1A, and the sewage discharged from the sewage facility 5 is discharged to the sewage main 8. As shown in FIG. 3, when a disaster such as an earthquake occurs, the temporary toilet 3 is installed in the temporary toilet piping facility 1A. In the following description, the normal usage mode is referred to as the normal mode, and the disaster usage mode is referred to as the disaster mode. FIG. 1 shows the state of the normal mode, and FIG. 3 shows the state of the disaster mode.

As shown in FIG. 1, in the normal mode, the toilet bowl 4a of the temporary toilet 3 is not provided at the upper end of the standing pipe 15. That is, the temporary toilet 3 is not used. As shown in FIG. 2, the upper end of the standing pipe 15 is covered with a lid 16. In normal mode, the second outlet 44 of the thirty thirty is blocked by the lid 32. Further, the gate outlet 78 of the gate 70 is in an open state. In the normal mode, the sewage discharged from the sewage facility 5 flows into the first pipe line 11 and then flows into the main body 31 from the inflow port 42 of 30 more and more. The sewage that has flowed into the main body 31 passes above the lid 32 (see FIG. 4) that is blocking the second outlet 44, and flows out of the main body 31 from the first outlet 43. The sewage flowing out from the first outlet 43 flows through the second pipe line 12 and flows into the sewage tank 60. After that, the sewage flows to the gate 70 through the third pipe line 13. At this time, since the gate outlet 78 of the gate 70 is open, the sewage flows into the fourth pipe line 14 and is discharged to the sewage main pipe 8. In the normal mode, only the sewage discharged from the sewage facility 5 flows through the main pipeline 10, and the sewage discharged from the temporary toilet 3 does not flow. In the normal mode, the rainwater that has flowed into the gutter 9 flows into the rainwater tank 80 through the rainwater conduit 19. Therefore, the rainwater tank 80 is in a state where rainwater is stored.

As shown in FIG. 3, in the disaster mode, the lid 16 arranged at the upper end of the standing pipe 15 is removed. Then, the toilet bowl 4a of the temporary toilet 3 is fixed to the ground so as to cover the upper end of the standing pipe 15, and the toilet bowl 4a is connected to the upper end of the standing pipe 15. A temporary hut 4b is installed on the ground so that a private room is formed for each toilet bowl 4a. The sewage mixed with excrement discharged from the temporary toilet 3 flows into the first pipe line 11 through the standing pipe 15. Then, the sewage that has flowed into the first pipeline 11 flows in the main pipeline 10 along the flow of the sewage or water that has flowed out from the sewage facility 5. Even in the disaster mode, sewage may flow toward the sewage main 8.

By the way, in the disaster mode, when the sewage main 8 is damaged, if the sewage flowing through the main pipeline 10 is discharged to the sewage main 8, there is a risk that the sewage may leak to the outside from the damaged part of the sewage main 8. There is. Therefore, when the sewage main 8 is damaged during a disaster, first, as shown in FIG. 9, the gate outlet 78 is closed by the closing member 72 of the gate 70. As a result, if the sewage main 8 is damaged during a disaster, the sewage discharged from the temporary toilet 3 to the first pipe 11 through the standing pipe 15 will be discharged to the sewage tank 60 because the gate outlet 78 is closed. It is stored.

For example, in the event of a disaster, water may not be supplied to the main pipeline 10 due to a failure of the sewage facility 5. When water is not supplied to the main pipe 10, the sewage discharged from the temporary toilet 3 to the first pipe 11 is difficult to flow toward the downstream side. In this case, in this embodiment, the rainwater of the rainwater tank 80 can be used. Specifically, as shown in FIG. 3, by operating the suction pump 95, the rainwater in the rainwater tank 80 flows into the suction pipe line 90 through the suction port 85. Then, the rainwater in the suction pipe line 90 is supplied to the first pipe line 11. Therefore, when water is not supplied from the sewage facility 5 to the main pipeline 10, the sewage discharged from the temporary toilet 3 to the first pipeline 11 uses the rainwater sucked from the rainwater tank 80 on the downstream side. Can be flushed to. Even when water is supplied from the sewage facility 5 to the main pipeline 10, the sewage discharged from the temporary toilet 3 to the first pipeline 11 is stored in the rainwater tank 80 in order to flow to the downstream side. You may use rainwater.

By the way, when the sewage main 8 is damaged and sewage is stored in the sewage tank 60, the amount of sewage that can be stored in the sewage tank 60 is limited. Therefore, for example, when the amount of sewage stored in the sewage tank 60 becomes larger than a predetermined amount, the sewage flows back, so that the sewage cannot flow into the sewage tank 60. In this case, it is advisable to switch the flow path of the sewage by 30 so that the sewage flows into the rainwater tank 80. Specifically, the operator removes the lid 32 of the 30th from the second outlet 44. As a result, the second outlet 44 is opened. At this time, as shown in FIG. 10, the second inflow port 84 of the rainwater tank 80 may be closed by the closing member 86.

In this case, the sewage discharged from the temporary toilet 3 through the vertical pipe 15 to the first pipe line 11 flows into the main body 31 from the inflow port 42 of 30 more and more. At this time, the second outlet 44 is opened from the lid 32, and the second outlet 44 is formed at the lower part of the main body 31, so that the sewage that has flowed into the main body 31 can be collected. It flows out of the main body 31 from the second outlet 44. The sewage flowing out from the second outlet 44 is discharged to the rainwater tank 80 through the sub-pipeline 18.

When the sewage discharged from the temporary toilet 3 to the first pipe line 11 is flowed to the downstream side by using the rainwater of the rainwater tank 80, it is possible that the rainwater is not stored in the rainwater tank 80. In this case, the sewage can be discharged to the empty rainwater tank 80 by switching the flow path of the sewage by 30. If rainwater is stored in the rainwater tank 80 when the sewage flow path is to be switched by the gutter 30, the rainwater stored in the rainwater tank 80 is discharged to the outside, and then the sewage is discharged. The flow path may be switched, or the flow path of sewage may be switched while rainwater is stored in the rainwater tank 80.

As described above, in the present embodiment, as shown in FIG. 3, when the temporary toilet 3 is installed in the event of a disaster such as an earthquake, the sewage discharged from the temporary toilet 3 goes to the sewage main 8 through the main pipeline 10. It is discharged. When the sewage main pipe 8 is damaged, as shown in FIG. 9, the fourth pipe line 14 is closed by closing the gate outlet 78 by the closing member 72 of the gate 70. As a result, the sewage discharged from the temporary toilet 3 can be stored in the sewage tank 60 without being discharged to the sewage main 8. Therefore, it is possible to prevent sewage from leaking to the outside from the damaged portion of the sewage main 8. When the amount of sewage stored in the sewage tank 60 reaches a predetermined amount, the flow path of the sewage is switched by 30 more. As a result, the sewage discharged from the temporary toilet 3 can be stored in the rainwater tank 80, and the sewage can be prevented from overflowing from the sewage tank 60. Therefore, if the sewage main 8 is damaged during a disaster, the temporary toilet 3 can be continued to be used even if the amount of sewage discharged from the temporary toilet 3 exceeds the storage limit of the sewage tank 60. Therefore, the sewage discharged from the temporary toilet 3 does not leak to the outside, and the temporary toilet 3 can be used continuously for a long time.

Further, in the present embodiment, the rainwater tank 80 is used as a tank for storing rainwater at a normal time other than a disaster. Therefore, since the rainwater tank 80 that is normally used can be used as a tank for urgently discharging sewage in the event of a disaster, it is not necessary to use a tank dedicated to the disaster. Therefore, the construction cost can be reduced and the construction space can be secured.

In the present embodiment, the sewage 30 has a sewage flow path switching function. The flow path of sewage can be easily switched by simply changing the position of the lid 32 of 30. By the way, foreign matter may flow in the main pipeline 10. In addition, after many years of use, deposits may accumulate on the main pipeline 10. Therefore, foreign matter or deposits may impair the flow path switching function of 30. However, as shown in FIG. 5, since the Masu 30 is provided with the inspection port 41, maintenance is easy. Therefore, when the foreign matter or the deposit is accumulated in the 30th, the foreign matter or the deposit can be easily removed from the inspection port 41. Therefore, in the event of a disaster, the flow path switching function can be sufficiently secured, and it becomes easy to avoid a situation in which the flow path cannot be switched.

In the present embodiment, as shown in FIG. 3, one end of the temporary toilet piping facility 1A is connected to the suction port 85 of the rainwater tank 80, and the other end is a portion upstream of the standing pipe 15 of the first pipe line 11. A suction pipe line 90 connected to the suction pipe line 90 and a suction pump 95 provided in the suction pipe line 90 are provided. By operating the suction pump 95, the rainwater stored in the rainwater tank 80 can be supplied to the first pipe line 11 through the suction pipe line 90. Therefore, the rainwater stored in the rainwater tank 80 can be used to discharge the excrement discharged from the temporary toilet 3 to any of the sewage main 8, the sewage tank 60, and the rainwater tank 80.

In the present embodiment, as shown in FIG. 10, the rainwater tank 80 includes a closing member 86 capable of closing the second inflow port 84. As a result, when the flow path of the sewage is switched and the sewage flows into the rainwater tank 80, the second inflow port 84 is closed by the closing member 86, so that the odor of the sewage is transmitted through the second inflow port 84. It is possible to suppress leakage to the outside. Further, by closing the second inflow port 84 by the closing member 86, it is possible to prevent the sewage from flowing back into the gutter 9 through the second inflow port 84.

In the present embodiment, as shown in FIG. 8, the center P11 of the tank inflow port 63 of the sewage tank 60 is arranged at the upper portion when the sewage tank 60 is divided into two equal parts in the vertical direction. The center P12 of the tank outlet 64 is arranged at a lower portion when the sewage tank 60 is divided into two equal parts in the vertical direction. As a result, the sewage that has flowed into the sewage tank 60 from the tank inflow port 63 falls toward the bottom surface of the sewage tank 60 and flows out to the third pipeline 13 through the tank outflow port 64. Therefore, in the sewage tank 60, the sewage can be smoothly flowed from the tank inlet 63 to the tank outlet 64.

Further, in the present embodiment, as shown in FIG. 10, the center P21 of the first inflow port 83 of the rainwater tank 80 and the center P22 of the second inflow port 84 divide the rainwater tank 80 into two equal parts in the vertical direction. It is arranged in the upper part when it is divided. As a result, when the flow path of the sewage is switched in the event of a disaster, the sewage can be stored in the rainwater tank 80 up to the water level at which the sewage reaches the lower end of the first inflow port 83 and the lower end of the second inflow port 84. Therefore, a relatively large amount of sewage is applied to the rainwater tank 80 as compared with the case where the center P21 of the first inflow port 83 and the center P22 of the second inflow port 84 are arranged in the lower portion of the rainwater tank 80. Can be stored.

The temporary toilet piping facility 1A according to the first embodiment has been described above. However, the temporary toilet piping equipment according to the present invention is not limited to the temporary toilet piping equipment 1A according to the first embodiment, and can be implemented in various other forms. Next, other embodiments will be briefly described. In the following description, the same reference numerals will be given to the same configurations as those already described, and the description thereof will be omitted.

<Second Embodiment>
Next, the temporary toilet piping facility 1B according to the second embodiment will be described. FIG. 11 is a front view of the temporary toilet piping facility 1B according to the second embodiment. As shown in FIG. 11, the temporary toilet piping facility 1B according to the present embodiment is a facility in which another 130 and another rainwater tank 180 are added to the temporary toilet piping facility 1A according to the first embodiment. .. The other Masu 130 has the same configuration as the Masu 30. The other 130 is an example of the "other flow path switching means" of the present invention. Further, the other rainwater tank 180 has the same configuration as the rainwater tank 80. Here, the description of the other gutter 130 and the other rainwater tank 180 will be omitted. In the following description, the symbols of the members and parts constituting the other members 130 will be used as the symbols of the members and parts constituting the other members 30. As the reference numerals of the members and parts constituting the other rainwater tank 180, the symbols of the members and parts constituting the rainwater tank 80 are used.

In the present embodiment, the first pipeline 11 has a first upstream pipeline 11a and a first downstream pipeline 11b. A vertical pipe 15 is connected to the first upstream pipe 11a. The first downstream pipeline 11b is arranged on the downstream side of the first upstream pipeline 11a. Another 130 is arranged between the first upstream line 11a and the first downstream line 11b. Here, the sewage facility 5 and the suction pipeline 90 are connected to the upstream end of the first upstream pipeline 11a. At the downstream end of the first upstream pipeline 11a, another 130 more and more inlets 42 are connected. The first outlet 43 of another 130 is connected to the upstream end of the first downstream pipeline 11b. An increasing number of 30 inlets 42 are connected to the downstream end of the first downstream pipeline 11b. The other 130 is another first state in which sewage is flowed from the first upstream line 11a to the first downstream line 11b, and another first state in which sewage is flowed from the first upstream line 11a to another rainwater tank 180. It is possible to switch to the state of 2.

In this embodiment, another rainwater tank 180 is connected to the second outlet 44 of the other 130. Specifically, one end of another sub-pipeline 118 is connected to the second outlet 44 of the other 130. The first inflow port 83 of the other rainwater tank 180 is connected to the other end of the other sub-pipeline 118. In this embodiment, one end of another rainwater pipeline 119 is connected to the second inflow port 84 of the other rainwater tank 180. Another gutter 109 is connected to the other end of the other storm sewer 119.

In the present embodiment, one end of the other suction pipe line 190 is connected to the suction port 85 of the other rainwater tank 180. The other end of the other suction line 190 is connected to the upstream end of the first line 11, that is, the upstream end of the first upstream line 11a. An other suction pump 195 is provided in the middle of the other suction pipe line 190. The other suction pump 195 has the same configuration as, for example, the suction pump 95.

In the present embodiment, when the sewage main 8 is damaged during a disaster, the gate outlet 78 is closed by the closing member 72 of the gate 70, as shown in FIG. As a result, the sewage discharged from the temporary toilet 3 through the vertical pipe 15 to the first pipe line 11 is stored in the sewage tank 60 because the gate outlet 78 is closed. At this time, in the other 130, the second outlet 44 is closed by the lid 32.

For example, when the sewage facility 5 fails and water is not supplied to the main pipe 10, the rainwater stored in the rainwater tank 80 is used to discharge the sewage discharged from the temporary toilet 3 to the first pipe 11 on the downstream side. The sewage discharged from the temporary toilet 3 to the first pipe line 11 may be flowed toward the downstream side by using the rainwater stored in the other rainwater tank 180. For example, when using the rainwater stored in the other rainwater tank 180, by operating the other suction pump 195, the rainwater in the other rainwater tank 180 can be collected through the suction port 85 of the other rainwater tank 180. It flows into another suction line 190. Then, the rainwater in the other suction pipe 190 is supplied to the first pipe 11. Therefore, when water is not supplied from the sewage facility 5 to the main pipeline 10, the sewage discharged from the temporary toilet 3 to the first pipeline 11 uses the rainwater sucked from the other rainwater tank 180 on the downstream side. It is possible to flush to.

Even in this embodiment, if the amount of sewage stored in the sewage tank 60 becomes larger than a predetermined amount, the flow path of the sewage can be switched by 30 so that the sewage flows into the rainwater tank 80. good. By the way, even when the sewage discharged from the temporary toilet 3 is poured into the rainwater tank 80 and the sewage is stored in the rainwater tank 80, the amount of sewage that can be stored in the rainwater tank 80 is limited. be. Therefore, for example, when the amount of sewage stored in the rainwater tank 80 becomes larger than a predetermined amount, the sewage flows back, so that the sewage cannot flow into the rainwater tank 80. In this case, the flow path of the sewage may be further switched by another 130 so that the sewage discharged from the temporary toilet 3 flows into the other rainwater tank 180. Specifically, the operator removes the other 130 lids 32 from the second outlet 44. This opens the second outlet 44 of the other 130. At this time, the second inflow port 84 of the other rainwater tank 180 may be closed by the closing member 86 (see FIG. 10).

In this case, the sewage discharged from the temporary toilet 3 through the vertical pipe 15 to the first upstream pipe 11a of the first pipe 11 flows into the main body 31 from the inflow port 42 of the other 130. At this time, since the second outlet 44 of the other 130 is opened from the lid 32, and the second outlet 44 is formed at the lower part of the main body 31, the other 130 The sewage that has flowed into the main body 31 flows out of the main body 31 from the second outlet 44 of the other 130. The sewage flowing out from the second outlet 44 of the other 130 is discharged to the other rainwater tank 180 through the other sub-pipeline 118.

As described above, even in this embodiment, the same effect as that in the first embodiment can be obtained. Further, in the present embodiment, when the flow path of sewage is switched by 30 in the event of a disaster, the sewage discharged from the temporary toilet 3 can be stored in the rainwater tank 80. If the amount of sewage stored in the rainwater tank 80 reaches a predetermined amount, the flow path of the sewage is further switched by another 130. At this time, the sewage discharged from the temporary toilet 3 can be stored in another rainwater tank 180. Therefore, if the sewage main 8 is damaged during a disaster, the sewage discharged from the temporary toilet 3 is discharged to any of the sewage tank 60, the rainwater tank 80, and the other rainwater tank 180. Therefore, the temporary toilet 3 is used. can do.

<Modification example>
In each of the above embodiments, the second outlet 44 of the thirty-third is formed at the lower part of the main body 31. However, the second outlet 44 may be formed on the side of the main body 31.

In each of the above embodiments, the flow path switching means of the present invention is more than 30. However, the flow path switching means of the present invention is not limited to 30. For example, the flow path switching means may be a joint capable of switching the flow path of sewage.

In each of the above embodiments, the rainwater tank 80 was indirectly connected to the second outlet 44 of the increasing 30 via the sub-pipeline 18. However, the rainwater tank 80 may be directly connected to the second outlet 44 of the gutter 30. In this case, for example, the first inflow port 83 of the rainwater tank 80 may be formed on the upper surface of the rainwater tank 80. Then, 30 may be placed on the upper surface of the rainwater tank 80 so that the first inflow port 83 and the second outflow port 44 overlap in the vertical direction.

In each of the above embodiments, the sewage storage space portion of the present invention was a sewage tank 60. However, the sewage storage space portion of the present invention is not limited to the sewage tank 60, and may be, for example, a storage pipe 160 as shown in FIG. The storage pipe 160 is a horizontally extending pipe. The storage pipe 160 has an inflow port 163 formed at the upstream end and an outflow port 164 formed at the downstream end. The inflow port 163 is connected to the downstream end of the second pipeline 12 via a replacement joint 161. The outflow port 164 is connected to the upstream end of the third pipeline 13 via a replacement joint 162. The diameter of the storage pipe 160 is larger than the diameter of the second pipe line 12 and larger than the diameter of the third pipe line 13. The cross-sectional area of the storage pipe 160 is larger than the cross-sectional area of the second pipe line 12 and larger than the cross-sectional area of the third pipe line 13. As described above, since the storage pipe 160 has a relatively short length in the vertical direction, the construction space of the storage pipe 160 can be reduced.
