Description

The present invention relates to a sewage discharge system.

For example, Patent Document 1 discloses a drainage facility for discharging wastewater including sewage discharged from a building to a sewage main. The above drainage facility has an internal drainage pipe that is arranged inside the building and through which drainage discharged from the building flows, and an external drainage pipe that is at least partially arranged outside the building and is connected to the sewage main. I have.

The upstream part of the external drainage pipe is arranged in the building, and the downstream part of the internal drainage pipe and the upstream part of the external drainage pipe are connected by a detachable joint. The joint is arranged in a space partitioned in the building, and the space functions as a storage tank in which the drainage flowing through the internal drainage pipe is discharged.

In the above drainage facility, the drainage that normally flows through the internal drainage pipe flows through the external drainage pipe through the joint and is discharged to the sewage main. On the other hand, if the sewage main is damaged, the joint is removed from the internal drainage pipe and the external drainage pipe. Therefore, when the sewage main or the like is damaged, the drainage flowing through the internal drainage pipe is discharged to a storage tank which is a space partitioned in the building.

Japanese Unexamined Patent Publication No. 10-266286

By the way, after the drainage is discharged to the storage tank, which is a space partitioned in the building, the storage tank is cleaned in order to restore the storage tank to its original state. The storage tank contains filth such as stool discharged from the toilet. Therefore, after sucking up the wastewater containing the filth stored in the storage tank with a vacuum device or the like, the inside of the storage tank is sterilized. As described above, in the above-mentioned drainage facility, after draining the drainage into the space partitioned in the building, there is a possibility that the labor required for cleaning and the cleaning cost for restoring the space to the original state may increase.

The present invention has been made in view of this point, and an object of the present invention is to provide a sewage discharge system capable of reducing the cleaning cost while saving the labor of cleaning for restoring the space where the sewage is discharged to the original state. It is to be.

The sewage discharge system according to the present invention includes a first sewage pipeline, a flow path switching member, a second sewage pipeline, and an accommodating body. The upstream end of the first sewage pipeline is connected to the sewage facility. The flow path switching member is connected to the downstream end of the first sewage pipeline and is capable of switching the flow path of sewage. The upstream end of the second sewage pipeline is connected to the flow path switching member, and the downstream end is connected to the sewage main. Sewage is contained in the container. The flow path switching member has a hollow main body and switching means. The main body has an inlet connected to the downstream end of the first sewage pipeline, a first outlet connected to the upstream end of the second sewage pipeline, and a predetermined discharge space in the building. It has a second outlet that opens toward the discharge space where sewage can be discharged. The switching means has a first switching position for communicating the inlet and the first outlet so that sewage does not flow from the inlet to the second outlet, and the first outlet from the inlet. The position can be changed between the second switching position for communicating the inlet and the second outlet so that the sewage does not flow into the sewage. The accommodating body includes an accommodating body in which an accommodating port communicating with the second outlet and an accommodating space communicating with the accommodating port and accommodating sewage flowing out from the second outlet are formed. It has and is arranged in the discharge space. The accommodation body is configured so that the shape of the accommodation space can be deformed.

According to the sewage discharge system, for example, when sewage is not discharged from the sewage facility to the sewage main, the switching means of the flow path switching member is arranged at the second switching position. At this time, the sewage discharged from the sewage facility flows through the first sewage pipeline and is discharged from the second outlet toward the discharge space in the building. In the present invention, the second outlet communicates with the accommodating port of the accommodating body. Therefore, the sewage flowing out from the second outlet is not directly discharged into the discharge space, but is discharged into the containment body. Therefore, when the discharge space is restored to its original state, the container itself containing the sewage may be discarded, so that the labor for cleaning the discharge space to be restored to the original state can be saved and the cleaning cost can be suppressed.

According to a preferred embodiment of the present invention, the enclosure is configured to be foldable.

According to the above aspect, the container can be stored in a folded state before using the container. Therefore, the space for storing the housing can be reduced. In addition, since the container can be carried in a folded state, it is easy to carry the container.

According to another preferred embodiment of the present invention, the housing in the folded state is formed on the member of the building forming the discharge space, and the worker is passed from the outside of the discharge space. It is configured to be able to pass through the passage port where it is possible.

According to the above aspect, the size of the passage port may be not a size that allows the unfolded container to pass through, but a size that allows the container to pass through the folded state. Therefore, the size of the passage port can be made relatively small. Further, the passage port is not a dedicated one through which the folded housing is passed, but can be used as a passage for the operator to enter the discharge space.

According to another preferred embodiment of the present invention, the container is a bag.

According to the above aspect, the container can be stored compactly. Further, when accommodating sewage in the accommodating body, the larger the amount of sewage contained in the accommodating body, the more the accommodating body expands. Therefore, when the amount of sewage contained in the container is small, the ratio of the container to the discharge space can be reduced.

According to another preferred embodiment of the present invention, the housing is attached to the main body so that the storage port is connected to the second outlet.

According to the above aspect, since the accommodating body is attached to the second outlet, the sewage flowing out from the second outlet can be prevented from leaking to the outside of the accommodating body.

According to another preferred embodiment of the present invention, the sewage discharge system includes a reinforcing body arranged so as to cover the container in the discharge space.

According to the above aspect, the accommodating body is reinforced by the reinforcing body. Therefore, when sewage is contained in the container, the container can be prevented from being damaged.

According to another preferred embodiment of the present invention, the accommodating body is arranged in a piping pit forming the discharge space.

When the discharge space is formed by the piping pit, for example, a pipeline other than the pipeline through which sewage flows is arranged in the discharge space. If the sewage flowing out from the second outlet is directly discharged into the discharge space formed by the piping pit, the sewage may adhere to the pipeline arranged in the discharge space. In this case, in order to clean the pipeline to which the sewage has adhered, the pipeline is sterilized or replaced with a new pipeline, which increases the labor and cleaning cost of a clean copy. However, according to the above aspect, the sewage flowing out from the second outlet is not directly discharged into the discharge space formed by the piping pit, but is discharged into the housing. Therefore, it is possible to save the trouble of cleaning the pipeline arranged in the discharge space and to reduce the cleaning cost.

According to the present invention, it is possible to provide a sewage discharge system capable of eliminating the labor of cleaning for restoring the space where sewage is discharged to the original state and suppressing the cleaning cost.

The second sewage pipeline 12 is arranged on the downstream side of the first sewage pipeline 11. The upstream end of the second sewage pipeline 12 is connected to the flow path switching member 20. The downstream end of the second sewage pipeline 12 is connected to the sewage main pipe 8. In the present embodiment, the upstream portion of the second sewage pipeline 12 is arranged in the building 3, and the portion other than the upstream portion of the second sewage pipeline 12 is buried in the ground. Although not shown, a so-called public sewage pipe may be provided in the middle of the second sewage pipeline 12.

The flow path switching member 20 is a member capable of switching the flow path of sewage. Specifically, the flow path switching member 20 creates a flow path of sewage so that the sewage discharged from the sewage facility 2 flows toward either the sewage main 8 or the discharge space 5 of the above pipe pit 4. It is something to switch. In the present embodiment, the flow path switching member 20 is arranged between the first sewage pipe 11 and the second sewage pipe 12 of the pipe 10, and is arranged in the building 3. Here, the flow path switching member 20 is arranged in the discharge space 5 of the piping pit 4. The flow path switching member 20 is provided on the floor 3a of the building 3.

In the present embodiment, the flow path switching member 20 is suspended and supported on the floor 3a. The method in which the flow path switching member 20 is suspended and supported by the floor 3a is not particularly limited. For example, a hanging band 61 is attached to the lower part of the floor 3a. The flow path switching member 20 is supported by the suspension band 61 and is provided on the floor 3a via the suspension band 61. Further, in the present embodiment, a hanging band 62 similar to the hanging band 61 is attached to the lower part of the floor 3a. The first sewage line 11 and the second sewage line 12 of the line 10 are supported by a hanging band 62. That is, the first sewage pipe 11 and the second sewage pipe 12 are suspended and supported by the floor 3a. In the present embodiment, the hanging bands 61 and 62 are made of metal, but the material forming the hanging bands 61 and 62 is not particularly limited.

FIG. 4 is a side view of the flow path switching member 20, and is a view seen from the first outlet 33 side. As shown in FIG. 2, the flow path switching member 20 includes a main body 21 and a lid 22. As shown in FIG. 4, the main body 21 is a hollow member, and the upper portion is formed in a substantially cylindrical shape with an enlarged diameter. As shown in FIG. 3, the main body 21 is formed with an inspection port 31, an inlet 32, a first outlet 33, and a second outlet 34.

The inspection port 31 is formed in the upper part of the main body 21 and opens upward. The operator inspects the inside of the main body 21 and the like through the inspection port 31. As shown in FIG. 1, an inspection cylinder 36 is connected to the inspection port 31. A lid 37 is detachably fitted in the upper end of the inspection cylinder 36. Since the inspection cylinder 36 is closed by the lid 37, it is possible to prevent the malodor generated from the sewage from leaking to the outside through the inspection port 31.

As shown in FIGS. 1 and 3, the inflow port 32 is formed on the side portion of the main body 21 and opens toward the side. The downstream end of the first sewage pipeline 11 is connected to the inflow port 32. The first outlet 33 is formed on the side portion of the main body 21 and opens toward the side. Here, the first outlet 33 faces the inlet 32 and is arranged on the opposite side of the inlet 32. The upstream end of the second sewage pipeline 12 is connected to the first outlet 33. The second outlet 34 is formed at the bottom of the main body 21 and opens downward. As shown in FIG. 1, the second outlet 34 opens toward the discharge space 5 of the piping pit 4.

The formation positions of the inlet 32, the first outlet 33, and the second outlet 34 with respect to the main body 21 are not particularly limited. The inflow port 32 and the first outflow port 33 may be formed, for example, at the bottom of the main body 21 and may open downward. The second outlet 34 may be formed, for example, on the side of the main body 21 and may be open toward the side.

As shown in FIG. 3, the lid 22 is a member that switches the flow path of sewage in the main body 21. In the present embodiment, the lid 22 is an example of the switching means. The lid 22 is detachably provided with respect to the main body 21. In this embodiment, it is detachably provided at the second outlet 34 of the main body 21.

In the present embodiment, the lid 22 can be arranged in the main body 21 so that sewage does not flow from the inflow port 32 to the second outflow port 34 and the inflow port 32 and the first outflow port 33 communicate with each other. The position of the lid 22 at this time corresponds to the "first switching position". The first switching position in the present embodiment is the position where the lid 22 is fitted into the second outlet 34. At the first switching position, the second outlet 34 is closed.

Further, in the present embodiment, the lid 22 can be arranged so that the sewage does not flow from the inlet 32 to the first outlet 33 and the inlet 32 and the second outlet 34 communicate with each other. The position of the lid 22 at this time corresponds to the "second switching position". The second switching position in the present embodiment is the position when the lid 22 is removed from the main body 21. At the second switching position, the first outlet 33 and the second outlet 34 are open.

As shown in FIG. 3, the lid body 22 includes a lid main body 41, a handle 42, and a fitting convex portion 43. As shown in FIG. 2, the lid body 41 has a bottom surface 45 that forms a flow path connecting the inlet 32 to the first outlet 33 when the lid 22 is attached to the second outlet 34. There is. The bottom surface 45 is formed in a substantially C-shaped cross section so as to be smoothly continuous with the bottom of the inlet 32 and the bottom of the first outlet 33. As shown in FIG. 3, the handle 42 is provided on the lid main body 41 so as to extend upward from the upper end of the lid main body 41. As shown in FIG. 2, the handle 42 is bridged over two upper ends of the lid main body 41.

As shown in FIG. 3, the fitting convex portion 43 is a portion that can be fitted to the second outlet 34 in order to close the second outlet 34. The fitting convex portion 43 is formed in a cylindrical shape. In the present embodiment, a rubber sealing member 44 is provided on the outer peripheral surface of the fitting convex portion 43. The seal member 44 is annular. The sealing member 44 can improve the sealing property between the second outlet 34 and the fitting convex portion 43 of the lid 22.

Next, the housing 50 shown in FIG. 1 will be described. The accommodation body 50 is for temporarily accommodating sewage. In the present embodiment, when the position of the lid 22 of the flow path switching member 20 is set to the second switching position and the second outlet 34 is opened, the sewage discharged from the sewage facility 2 is collected in the flow path switching member 20. It flows out from the second outlet 34. The sewage flowing out from the second outlet 34 is housed in the container 50, and the sewage is temporarily stored.

The accommodating body 50 is arranged in the discharge space 5 in the piping pit 4 of the building 3. In the present embodiment, the lid 22 of the flow path switching member 20 is the second switching position, and when the sewage flows out from the second outlet 34, the sewage is not directly discharged to the discharge space 5, but is a discharge space. It is difficult to adhere to the members constituting the piping pit 4 forming the 5.

The accommodating body 50 is attached to the main body 21 of the flow path switching member 20. The configuration of the housing 50 is not particularly limited. In the present embodiment, as shown in FIG. 1, the accommodating body 50 has an accommodating body 51. The housing body 51 is hollow. The space inside the accommodation body 51 is called the accommodation space 52. A storage port 53 is formed in the storage body 51. The accommodation port 53 communicates with the accommodation space 52. In the present embodiment, the accommodating body 50 is directly connected to the second outlet 34, and more specifically, the accommodating port 53 is connected to the second outlet 34. The second outlet 34 and the accommodation port 53 communicate with each other. The sewage flowing out from the second outlet 34 is discharged to the accommodation space 52 through the accommodation port 53.

The configuration in which the housing body 50 is attached to the main body 21 is not particularly limited. In the present embodiment, for example, the portion of the main body 21 forming the second outlet 34 is covered with the portion of the accommodating main body 51 forming the accommodating port 53. Then, the accommodating body 50 is adhesively fixed to the main body 21 by using a tape having an adhesive layer.

In the present embodiment, the shape of the accommodation space 52 of the accommodation body 50 is configured to be deformable. In other words, the shape of the storage body 51 forming the storage space 52 is configured to be deformable according to the amount of sewage stored in the storage space 52. The type of the housing 50 is not particularly limited. In the present embodiment, the housing body 50 is, for example, a bag body. Here, the bag body means a bag body that does not swell due to its own weight when there is no object inside, but is configured to swell when an object enters inside. The specific type of bag is not particularly limited, but examples of the bag include a bottom seal bag, a side seal bag, a three-way seal bag, a four-way seal bag, a pillow bag, a pouch-shaped bag, and a standing pouch-shaped bag that can stand on its own. , Chuck bag, vacuum molded bag, circular seal bag and the like. Further, the housing body 50 may be a bag body made of chemical fiber such as a so-called flexible container bag.

When the accommodation body 50 does not contain sewage in the accommodation space 52, the accommodation body 51 does not inflate due to the weight of the accommodation body 51, and the accommodation body 51 inflates as the sewage is discharged into the accommodation space 52. It is configured. In other words, the storage body 51 is configured to swell as the amount of sewage discharged into the storage space 52 increases. In the present embodiment, the accommodation space 52 can accommodate the amount of sewage discharged from the sewage facility 2 for several days (for example, a few days). For example, the maximum amount of sewage that can be accommodated in the accommodation space 52 of the accommodation body 50 is smaller than the maximum amount of sewage that can be discharged into the discharge space 5 of the piping pit 4. However, the maximum amount of sewage that can be accommodated in the accommodation space 52 may be larger than the maximum amount of sewage that can be discharged into the discharge space, or may be the same as the maximum amount of sewage that can be discharged into the discharge space. ..

In this embodiment, the housing 50 is configured to be foldable. When the amount of sewage contained in the accommodation space 52 is small, the accommodation body 50 can be folded and can be assembled more compactly. However, the housing 50 may be disassembled into a plurality of members. For example, when the accommodation body 50 is put in the discharge space 5, the housing body 50 in a disassembled state may be put in, and the housing body 50 may be assembled in the discharge space 5.

The material forming the accommodating body 50, in other words, the material forming the accommodating body 51 is not particularly limited. In the present embodiment, the accommodating body 50 (here, the accommodating body 51) is formed of resin. As an example of the material forming the accommodating body 51 of the accommodating body 50, for example, soft polyethylene can be mentioned. Further, the accommodating body 50 (here, the accommodating body 51) may be formed of a transparent or translucent material, or may be formed of an opaque material. By forming the accommodating body 51 with a transparent or translucent material, the amount of sewage contained in the accommodating body 50 can be easily visually understood.

In the present embodiment, as shown in FIG. 1, a passage port 6 is formed in the piping pit 4 of the building 3. The passage port 6 is formed on the material of the building 3 forming the discharge space 5, in this case, the upper surface of the piping pit 4, that is, the floor 3a constituting the piping pit 4. Through the passage port 6, the discharge space 5 of the piping pit 4 and the outside of the piping pit 4 (for example, the space above the floor 3a) are communicated with each other. The passage port 6 is larger than the inspection port 31 of the flow path switching member 20, for example. However, the passage port 6 may be the same size as the inspection port 31 or may be smaller than the inspection port 31.

In the present embodiment, the passage port 6 allows the operator to pass from the outside of the discharge space 5 (for example, on the floor 3a). The passage port 6 is about the same size as a so-called manhole. However, the passage port 6 may be of a size that allows an operator to pass his / her hand from the outside of the discharge space 5. The operator puts the folded housing body 50 into the discharge space 5 of the piping pit 4 through the passage port 6. The housing 50 in the folded state is configured to be able to pass through the passage port 6.

In the present embodiment, as shown in FIG. 1, the sewage discharge system 1 may include a reinforcing body 55. The reinforcing body 55 reinforces the accommodating body 50. For example, if more sewage than expected is contained in the container 50, a sharp object is mistakenly placed in the discharge space 5, or a sharp object is mixed in the sewage, the container 50 is damaged. There can be. Therefore, by reinforcing the accommodating body 50 with the reinforcing body 55, the accommodating body 50 can be made less likely to be damaged.

The reinforcing body 55 is arranged so as to cover the accommodating body 50 in the discharge space 5 of the piping pit 4. The reinforcing body 55 may be in contact with the bottom surface of the piping pit 4 forming the discharge space 5, or may be arranged so as to float above the bottom surface and may be provided by the ceiling of the piping pit 4 forming the discharge space 5. It may be supported. At least a part of the reinforcing body 55 is in contact with the housing body 51 of the housing body 50.

Like the accommodating body 50, the reinforcing body 55 may be configured so that the shape of the reinforcing body 55 can be deformed. Further, the reinforcing body 55 may be configured to be foldable, or may be disassembled into a plurality of members, and the plurality of members may be assembled. For example, the reinforcing body 55 in a folded state or the reinforcing body 55 disassembled into a plurality of members is configured to be able to pass through the passage port 6 of the piping pit 4.

In the present embodiment, the reinforcing body 55 is in the shape of a container that opens upward. In this case, the accommodating body 50 is accommodated in the reinforcing body 55. For example, the reinforcing body 55 is formed in a container shape by inflating when air is introduced, and is like a so-called vinyl pool. However, the type of the reinforcing body 55 is not particularly limited. The reinforcing body 55 is composed of a frame, and a hole may be formed in a part thereof. Further, the reinforcing body 55 may be a foldable bag body. Examples of the bag body include those made of chemical fibers such as flexible container bags. The reinforcing body 55 may be made of a transparent or opaque material, or may be made of an opaque material. The reinforcing body 55 can be omitted, and the housing body 50 may not be covered by the reinforcing body 55.

The reinforcing body 55 may be the same as the housing body 50. For example, when the housing 50 is a bag made of soft polyethylene, the reinforcing body 55 may also be a bag made of soft polyethylene. Further, the reinforcing body 55 may be a stack of a plurality of reinforcing members. For example, the reinforcing body 55 may be a stack of a plurality of bags. For example, when two or more bag bodies are stacked, the innermost bag body functions as the accommodating body 50, and the bag body other than the innermost one functions as the reinforcing body 55.

The configuration of the sewage discharge system 1 according to the present embodiment has been described above. Next, a method of using the sewage discharge system 1 will be described. The sewage discharge system 1 normally discharges the sewage discharged from the sewage facility 2 to the sewage main 8. On the other hand, when a disaster such as an earthquake or a tsunami occurs and the sewage main 8 is damaged, for example, the sewage discharge system 1 switches the sewage flow path by the flow path switching member 20 and discharges the sewage from the sewage facility 2. The sewage is discharged to the housing 50. In the following description, the normal usage mode is referred to as "normal mode", and the disaster usage mode is referred to as "disaster mode".

In the normal mode, as shown in FIG. 3, the position of the lid 22 of the flow path switching member 20 is the first switching position, and the second outlet 34 of the flow path switching member 20 is closed by the lid 22. Has been done. In the normal mode, as shown in FIG. 1, the sewage discharged from the sewage facility 2 flows into the main body 21 from the inflow port 32 of the flow path switching member 20 through the first sewage pipeline 11. The sewage that has flowed into the main body 21 of the flow path switching member 20 passes through the bottom surface 45 of the lid 22 that closes the second outflow port 34, and flows out of the main body 21 from the first outflow port 33. The sewage flowing out from the first outlet 33 is discharged to the sewage main 8 through the second sewage pipeline 12. Then, the sewage discharged to the sewage main 8 is guided to a sewage treatment plant (not shown) or the like for purification treatment.

In the disaster mode, the position of the lid 22 of the flow path switching member 20 is the second switching position. In the disaster mode, the lid 22 is removed from the second outlet 34 and the second outlet 34 is opened. The lid 22 can be removed, for example, as follows. First, the operator removes the lid 37 fitted in the inspection cylinder 36 connected to the inspection port 31 of the flow path switching member 20. Next, the lid 22 is pulled up by holding the handle 42 of the lid 22. As a result, the second outlet 34 of the flow path switching member 20 is opened. If the handle 42 cannot be reached, for example, a rod-shaped body having a hook at the tip may be used to hook the hook on the handle 42 and pull up the lid 22.

Further, in the disaster mode, the accommodating body 50 is attached to the main body 21 of the flow path switching member 20. In other words, in the disaster mode, the accommodation body 50 is arranged in the discharge space 5 of the piping pit 4 so that the sewage is discharged from the second outlet 34 to the accommodation body 50. The housing 50 can be attached to the main body 21 as follows, for example. First, the worker folds the housing body 50 to the extent that the housing body 50 can pass through the passage port 6. Next, the operator passes the folded housing body 50 through the passage port 6 and inserts the housing body 50 into the discharge space 5 of the piping pit 4. At this time, the work of inserting the folded reinforcing body 55 into the discharge space 5 from the passage port 6 may be performed at the same time. After that, the worker enters the discharge space 5 through the passage port 6, arranges the reinforcing body 55 so as to cover the accommodating body 50, and connects the accommodating port 53 of the accommodating body 50 to the second outlet 34. conduct. However, the worker only puts his / her hand in the discharge space 5 through the passage port 6, that is, the work of connecting the storage port 53 to the second outlet 34 while the worker's body and the like are outside the discharge space 5. May be done. As a result, the accommodation body 50 can be connected to the second outlet 34.

In the disaster mode, the sewage discharged from the sewage facility 2 flows into the main body 21 from the inflow port 32 of the flow path switching member 20 after flowing through the first sewage pipeline 11. At this time, since the second outlet 34 is open and the second outlet 34 is formed in the lower part of the main body 21, the sewage flowing into the main body 21 of the flow path switching member 20 is the first flow. Before reaching the outlet 33, it flows out of the main body 21 from the second outlet 34. The sewage flowing out from the second outlet 34 is discharged to the accommodation space 52 through the accommodation port 53 of the accommodation body 50. As the sewage is discharged into the accommodation space 52 of the accommodation body 50, the accommodation main body 51 (in other words, the accommodation space 52) expands while the shape of the accommodation space 52 is deformed.

When disposing of the sewage in the housing 50, for example, a suction hose (not shown) is inserted from the inspection port 31 of the flow path switching member 20, and the suction hose is passed through the second outlet 34. It is inserted into the accommodation space 52 of the accommodation body 50. After that, a suction device (for example, a vacuum car) connected to the suction hose is driven to suck the sewage contained in the storage space 52. As a result, the sewage in the accommodation space 52 is discharged to the outside through the suction hose, and the sewage is removed from the accommodation space 52. After the sewage in the containment space 52 is removed, the containment body 50 is discarded. In this case, the operator enters the discharge space 5 through the passage port 6 and removes the accommodation body 50 from the second outlet 34. The operator may remove the accommodating body 50 from the second outlet 34 with only his / her hand in the discharge space 5. Then, the accommodating body 50 is folded, and the folded accommodating body 50 is taken out from the passage port 6 to the outside of the piping pit 4. The housing 50 taken out from the piping pit 4 is discarded. The reinforcing body 55 may remain arranged in the discharge space 5 of the piping pit 4, or may be taken out from the piping pit 4. Further, the reinforcing body 55 may be discarded together with the housing body 50, or may be used repeatedly.

If the accommodating body 50 can be taken out from the passage port 6 while the sewage is contained in the accommodating space 52, the accommodating body 50 in the state where the sewage is contained is removed from the second outlet 34. May be good. The accommodating body 50 removed from the second outflow port 34 is taken out of the piping pit 4 from the passage port 6 in a state where sewage is accommodated. Then, the housing 50 taken out from the piping pit 4 is discarded together with the sewage.

As described above, in the present embodiment, as shown in FIG. 1, the sewage discharge system 1 includes a first sewage pipeline 11, a flow path switching member 20, a second sewage pipeline 12, and an accommodating body in which sewage is accommodated. It has 50 and. The upstream end of the first sewage pipeline 11 is connected to the sewage facility 2. The flow path switching member 20 is a member connected to the downstream end of the first sewage pipeline 11 and capable of switching the flow path of sewage. The upstream end of the second sewage pipeline 12 is connected to the flow path switching member 20, and the downstream end is connected to the sewage main pipe 8. As shown in FIG. 3, the flow path switching member 20 has a main body 21 and a lid 22. As shown in FIG. 1, the main body 21 has an inlet 32 connected to the downstream end of the first sewage pipeline 11, a first outlet 33 connected to the upstream end of the second sewage pipeline 12, and a building. It is a predetermined discharge space 5 in 3 and has a second outlet 34 opened toward the discharge space 5 where sewage can be discharged, and is hollow. The lid 22 has a first switching position for communicating the inlet 32 and the first outlet 33 so that sewage does not flow from the inlet 32 to the second outlet 34, and the first outlet 33 from the inlet 32. The position can be changed between the inflow port 32 and the second switching position in which the second outflow port 34 communicates with each other so that sewage does not flow into the water. The accommodating body 50 is arranged in the discharge space 5. The accommodating body 50 has an accommodating port 53 communicating with the second outlet 34 and an accommodating space 52 communicating with the accommodating port 53 and accommodating sewage flowing out from the second outlet 34. It has a main body 51.

According to the present embodiment, when the sewage is not discharged from the sewage equipment 2 to the sewage main 8 in the disaster mode, the lid 22 of the flow path switching member 20 is arranged at the second switching position, and the flow path switching member is arranged. The second outlet 34 of 20 is opened. At this time, the sewage discharged from the sewage facility 2 flows through the first sewage pipeline 11 and is discharged from the second outlet 34 toward the discharge space 5 in the building 3. Here, the second outlet 34 communicates with the accommodation port 53 of the accommodation body 50. Therefore, the sewage flowing out from the second outlet 34 is not directly discharged to the discharge space 5, but is discharged into the housing 50. Therefore, when the discharge space 5 is restored to its original state, the container 50 itself containing the sewage may be discarded, so that the labor for cleaning the discharge space 5 to the original state can be saved and the cleaning cost can be suppressed. Can be done.

Further, in the present embodiment, the accommodation body 50 is configured so that the shape of the accommodation space 52 can be deformed. Therefore, even if a pipeline or a tool used by a worker is arranged in the discharge space 5, the housing 50 is changed in shape so as to avoid the pipeline or the tool, and is a discharge space. Can be arranged at 5.

In this embodiment, the housing 50 is configured to be foldable. As a result, the container 50 can be stored in a folded state before the container 50 is used. Therefore, the space for storing the housing 50 can be reduced. Further, since the accommodating body 50 can be carried in a folded state, the accommodating body 50 can be easily carried.

In the present embodiment, the housing 50 in the folded state has a passage port 6 formed in a member of the building 3 forming the discharge space 5 and allowing an operator to pass from the outside of the discharge space 5. It is configured to be passable. Here, the size of the passage port 6 may be not a size that allows the unfolded housing body 50 to pass through, but a size that allows the housing body 50 in the folded state to pass through. Therefore, the size of the passage port 6 can be made relatively small. Further, the passage port 6 is not a dedicated one through which the folded state accommodating body 50 passes, but can be used for the operator to enter the discharge space 5.

In the present embodiment, the housing body 50 is a bag body. As a result, the accommodation body 50 can be stored compactly. Further, when accommodating sewage in the accommodating body 50, the larger the amount of sewage accommodated in the accommodating body 50, the more the accommodating body 50 expands. Therefore, when the amount of sewage contained in the container 50 is small, the ratio of the container 50 to the discharge space 5 can be reduced.

In the present embodiment, the accommodating body 50 is attached to the main body 21 so that the accommodating port 53 is connected to the second outlet 34. By attaching the accommodating body 50 to the main body 21 in this way, the sewage flowing out from the second outlet 34 can be prevented from leaking to the outside of the accommodating body 50.

In the present embodiment, the reinforcing body 55 is arranged so as to cover the accommodating body 50 in the discharge space 5. As a result, the accommodating body 50 is reinforced by the reinforcing body 55. Therefore, when the sewage is contained in the container 50, the container 50 can be prevented from being damaged.

In the present embodiment, the accommodation body 50 is arranged in the piping pit 4 forming the discharge space 5. When the discharge space 5 is formed by the piping pit 4, for example, a pipe line other than the pipe line 10 through which sewage flows (for example, a gas pipe line through which gas flows) is arranged in the discharge space 5. If the sewage flowing out from the second outlet 34 is directly discharged into the discharge space 5 formed by the piping pit 4, the sewage may adhere to the gas pipeline or the like arranged in the discharge space 5. .. In this case, in order to clean the pipeline to which sewage has adhered, the pipeline is sterilized or replaced with a new pipeline, which increases the labor and cleaning cost of a clean copy. However, in the present embodiment, the sewage flowing out from the second outlet 34 is not directly discharged into the discharge space 5 formed by the piping pit 4, but is discharged into the accommodation body 50. Therefore, it is possible to save the trouble of cleaning the gas pipeline or the like arranged in the discharge space 5, and it is possible to suppress the cleaning cost.

In the above embodiment, the container 50 is a bag body, but the container body of the present invention is not limited to the bag body. FIG. 5 is a front view showing the sewage discharge system 1A according to another embodiment. For example, as shown in FIG. 5, the sewage discharge system 1A includes an accommodating body 50A. The housing 50A is in the shape of a container with an open upper part. The housing body 50A can be inflated by injecting air. The container 50A is formed in the shape of a container, for example, by injecting air. The housing 50A is like a so-called vinyl pool.

In the present embodiment, the accommodating body 50A has an accommodating body 51A formed in a container shape when air is introduced. The space surrounded by the container-shaped storage body 51A is the storage space 52A. The portion of the container-shaped storage body 51A that opens upward is the storage port 53A. Further, in the present embodiment, the housing body 50A can be folded when the air is evacuated. Even in other embodiments, the accommodating body 50A may be covered with the reinforcing body 55 or may be reinforced by the reinforcing body 55, as in the above embodiment.

In the present embodiment, the accommodating body 50A is arranged in the discharge space 5 of the piping pit 4 so that the sewage is discharged from the second outlet 34 to the accommodating body 50A in the disaster mode. Here, first, the worker folds the accommodation body 50A to the extent that the accommodation body 50A can pass through the passage port 6. Next, the worker passes the folded body 50A through the passage port 6 and puts it in the discharge space 5 of the piping pit 4. After that, the worker injects air into the accommodating body 50A to make the accommodating body 51A into a container shape. The container-shaped accommodating body 50A is placed on the bottom surface of the piping pit 4 so that the accommodating port 53A is located directly below the second outlet 34. As a result, in the disaster mode, the sewage flowing out from the second outlet 34 falls from the second outlet 34 and is discharged to the accommodation space 52A through the accommodation port 53A of the accommodation body 50A.

When disposing of the sewage in the housing 50A, the suction hose and the suction device are used to suck the sewage in the storage space 52A of the housing 50A in the same manner as the housing 50 of the embodiment. You should remove it. After the sewage in the containment space 52A is removed, when disposing of the containment body 50A, the operator deflate the containment body 50A and fold the containment body 50A. Then, the folded body 50A is taken out of the piping pit 4 from the passage port 6. The housing 50A taken out from the piping pit 4 is discarded.

Even in this embodiment, the sewage flowing out from the second outlet 34 is not directly discharged into the discharge space 5, but is discharged into the housing 50A. Therefore, when the discharge space 5 is restored to its original state, the container 50A itself containing the sewage may be discarded, so that the labor for cleaning the discharge space 5 to its original state can be saved and the cleaning cost can be suppressed. ..
