In a temporary toilet using a conventional temporary toilet system as disclosed in Patent Document 1, a tent-type or panel assembly-type temporary hut is installed as a temporary hut that forms a private space around a toilet bowl .

However, tent-type or panel-assembled temporary huts do not necessarily provide a safe and secure space, as illumination light can pass through at night and show the user's silhouette, and the locks and materials themselves are fragile. There is a problem.

Further, the temporary toilet system of Patent Document 1 drains water every time it is used multiple times (for example, every two hours), and is different from a flush toilet that is normally used in normal times. Immediately after a disaster, the minimum necessary toilets can satisfy the needs of users, but even after a certain period of time has passed after a disaster, and electricity and water supply have been restored, it is not always possible to It cannot be said that it satisfies the needs of users. During the Kumamoto Earthquake that occurred in April 2016, many people developed economy class syndrome due to restricted lifestyles such as not drinking enough water and sleeping in cars in order to avoid using the toilet. In some cases, it was life-threatening, and it became a problem. Tank-type temporary rental toilets, which are used at construction sites, have been installed in some evacuation shelters, but the smell from the urinals accumulated in the tank and the difference in level caused by the tank are similar to those of flush toilets that are used on a daily basis. Far from this, there is a lack of perspective on providing comfortable temporary toilets that would ease the burden of living in evacuation centers.

Furthermore, when newly installing the temporary toilet system of Patent Document 1, many people who are considering installing a facility are hesitant about spending money on a facility that can only be used in times of disaster. It is desirable that it can be used not only during disasters, but also during events such as cherry blossom viewing, fireworks displays, and festivals, but tent-type or panel-assembled temporary huts are not safe and secure as temporary toilets for normal use, as mentioned above. The problem is that it is not possible to provide a space that is

FIG. 16 is an illustrative view showing a raised bottom part of the temporary toilet of FIG. 15;

Referring to FIGS. 1 and 2, a temporary toilet system 10 (hereinafter simply referred to as "system 10"), which is an embodiment of the present invention, includes a plurality of vertical pipe members 12, a drain pipe 14, and a fixing fulcrum. 16, etc., and are constructed in advance (that is, permanently installed) underground in empty spaces such as schools, parks, or condominiums that serve as evacuation sites in the event of a disaster. When used during disasters, events, etc., the toilet bowl 102 and the temporary hut 104 are attached to predetermined positions, so that the toilet 100 is used as a temporary toilet.

As shown in FIGS. 1 to 3, the vertical pipe members 12 are members that are buried underground in correspondence with the predetermined installation positions of the toilet bowls 102. In this embodiment, five vertical pipe members 12 are installed. are arranged in a straight line every 2000 mm. The inner diameter of the vertical tube member 12 is, for example, 300 mm.

As the vertical pipe member 12, a known synthetic resin sewage basin (small manhole) or the like can be used. In this embodiment, a sewage basin made of hard vinyl chloride is used as the vertical pipe member 12, and includes a ribbed horizontal pipe part 12a and a riser pipe part 12b having a swinging function. Further, by connecting the straight pipe 12c for length adjustment to the upper end of the riser pipe portion 12b, the length of the vertical pipe member 12 can be adjusted as appropriate depending on the buried position thereof. However, the number, shape, material, arrangement, etc. of the vertical tube members 12 can be changed as appropriate depending on the situation such as the installation location.

The drain pipe 14 connects the lower ends (horizontal pipe parts 12a) of the vertical pipe members 12 and is arranged at a predetermined downward slope of, for example, 18 mm/1000 mm. The drain pipe 14 is a ribbed pipe having a plurality of ribs formed on its outer peripheral surface, and is made of synthetic resin such as hard vinyl chloride. The inner diameter of the drain pipe 14 is, for example, 150 mm.

The downstream end of the drain pipe 14 is connected to a public basin 106 that connects to a sewer main pipe 108. That is, the drain pipe 14 connects the plurality of vertical pipe members 12 and the public basin 106. On the other hand, a water supply tank (water supply tank for drain pipe) 18 is provided at the upstream end of the drain pipe 14 for sending cleaning water into the drain pipe 14 . The water supply tank 18 is formed of a synthetic resin such as hard vinyl chloride into a rectangular tube shape with a bottom, and a lid is removably attached to the opening at the upper end. An outlet 18a connected to the upstream end of the drain pipe 14 is formed at the lower end of the side wall of the water tank 18, and a gate valve (not shown) is provided at the outlet 18a. The water supplied into the water supply tank 18 is allowed to flow into the drain pipe 14 from the outlet 18a as cleaning water by opening the gate valve. However, the gate valve does not necessarily need to be provided, and the water supplied into the water supply tank 18 may be directly supplied into the drain pipe 14 from the outlet 18a. Further, the material, shape, etc. of the water tank 18 can be changed as appropriate.

As a water supply source for supplying water for cleaning into the water supply tank 18, it is preferable to use a water tank, a well, a water pipe, or the like in which rainwater, tap water, or the like is stored in advance. For example, if RAIN Bo Stadium II (product name), a rainwater storage tank manufactured and sold by the applicant, etc., is installed adjacent to the piping route of the drain pipe 14, the rainwater accumulated in this rainwater storage tank may be is preferably supplied into the water tank 18.

A plurality of vertical pipe members 12, drain pipes 14, and water tanks 18 as described above are used as drainage equipment of the temporary toilet 100.

Furthermore, a synthetic resin pedestal 20 is embedded so as to surround the upper end of each vertical tube member 12. A protective lid 22 composed of a receiving frame, an inner lid, an iron lid (vertical pipe lid) 22a, and the like is placed on this pedestal 20. That is, a substantially rectangular cylindrical iron receiving frame is placed on the pedestal 20 . The lower end of this receiving frame is formed into a tapered shape, and a substantially short cylindrical lower end opening is formed therein. Further, an iron lid 22a facing the ground surface (that is, substantially flush with the ground surface) is provided at the upper end opening of the receiving frame, and an inner lid is attached to the lower end opening of the receiving frame. By removing the iron cover 22a and the inner cover of the protective cover 22, the upper end opening of the vertical tube member 12 is opened to the outside.

In this embodiment, a fixing fulcrum 16 used for fixing the temporary hut 104 is embedded in advance around the vertical pipe member 12. This fixing fulcrum 16 is connected to a fixing member 110 such as a rope or wire for fixing the temporary hut 104, and is not particularly limited in its arrangement. , two are provided on each side of the vertical tube member 12. Note that the fixing fulcrum 16 provided between adjacent vertical pipe members 12 is also used for fixing the temporary huts 104 on both sides.

Specifically, as shown in FIG. 4, in this embodiment, a spectacle stake having a ring-shaped portion 16a at the upper end and a bent portion 16b at the lower end is used as the fixing fulcrum 16. Further, a pipe member 30 made of synthetic resin such as hard vinyl chloride is buried underground so as to surround the fixing fulcrum 16 . The pipe member 30 includes an upper small diameter part 30a, a lower large diameter part 30b, and a tapered part 30c connecting these parts, and the pipe member 30 is filled with concrete 34 leaving a space 32 at the upper end. Ru. The inner diameter of the small diameter portion 30a of the tube member 30 is, for example, 50 mm, and the inner diameter of the large diameter portion 30b is, for example, 100 mm. Further, the axial length of the tube member 30 is, for example, 400 mm. The fixing fulcrum 16 is fixed by being embedded in the concrete 34 so that the ring-shaped portion 16a protrudes into the space 32.

Further, a lid (fulcrum lid) 36 made of synthetic resin and facing the ground surface is attached to the upper end opening of the tube member 30 so as to be openable and closable. That is, the fixing fulcrum 16 is covered from above by the lid 36 which is substantially flush with the ground surface, and is exposed to the outside by removing (opening) the lid 36. Therefore, during normal times (when not in use) when the system 10 is not in use, the fixing fulcrum 16 does not get in the way. Furthermore, the fixing fulcrum 16 can be easily used when desired.

However, the specific shape and installation mode of the fixing fulcrum 16 can be changed as appropriate. For example, although the lid body 36 is removable from the tube member 30 in this embodiment, it may be connected to the tube member 30 so as to be openable and closable using a hinge or the like. For example, as shown in FIG. 5, a P-shaped spectacle stake (P anchor) having a D-shaped portion 16c at the upper end and a plurality of annular protrusions 16d formed on the outer peripheral surface is used as the fixing fulcrum 16. You can also do that. In the case of the fixing fulcrum 16 shown in FIG. 5, the fixing fulcrum 16 is driven into the ground using a hammer or the like. Further, a short tube member 30 is provided so as to form a space 32 around the D-shaped portion 16c of the fixing fulcrum 16, and the upper end opening of the tube member 30 is provided with a synthetic resin tube facing the ground surface. The lid body 36 is removably attached. Furthermore, for example, the fixing fulcrum 16 may be fixed using a receiving frame of the protective lid 22. Furthermore, the fixing fulcrum 16 does not necessarily need to be covered by the lid 36, and may be installed with connecting parts such as the ring-shaped part 16a and the D-shaped part 16c protruding from the ground surface.

By burying (that is, permanently installing) such a fixing fulcrum 16 in advance during construction of the system 10, there is no need to temporarily install the fixing fulcrum 16 in the event of a disaster, etc., so that the work of fixing the temporary shed 104 is facilitated. Become. Moreover, the fixing fulcrum 16 can also be made strong. That is, by permanently providing the fixing fulcrum 16, the temporary hut 104 can be easily and firmly fixed.

By constructing the system 10 as described above underground in advance, it becomes possible to quickly and easily install the temporary toilet 100 in the event of a disaster or an event.

6 together with FIGS. 1 and 2, when the system 10 is used as a temporary toilet 100, the iron cover 22a and the inner cover of the protective cover 22 are removed, and the toilet bowl 102 is placed above each vertical pipe member 12. and a temporary shed 104 that forms a private room space around the toilet bowl 102. When installing the temporary hut 104, remove the lid 36 to expose the fixing fulcrum 16, and connect the fixing member 110 that spans the temporary hut 104 to the fixing fulcrum 16. Fix it.

In this embodiment, a flush-type Western-style toilet bowl is used as the toilet bowl 102 in order to provide the user with a safe and comfortable toilet space even in the event of a disaster. This toilet bowl 102 may be made of ceramic, resin, or other materials. Further, as the temporary hut 104, a box-shaped hut is used, which is stronger and safer than a tent-type or panel assembly type. Specifically, the temporary hut 104 of this embodiment is a box-shaped hut having a lockable door 104a, and is made of synthetic resin such as polyethylene. The side walls, bottom wall, door 104a, etc. of the temporary hut 104 are constructed of hollow double walls. Furthermore, a groove portion 104b for spanning the fixing member 110 is formed in the ceiling wall of the temporary hut 104.

Furthermore, the temporary hut 104 is also provided with a low tank 112 that supplies water for flushing the toilet bowl 102, lighting equipment, a ventilation fan, etc. (not shown), and the like. A temporary water supply pipe 116 for flushing, which is arranged along the ground surface, is connected to the low tank 112 from a water faucet 114 installed in advance on the ground. Water for rinsing will be provided. However, the faucet 114 for connecting the temporary water supply pipe 116 for flushing may be buried underground in advance. By providing the water faucet 114 above or underground in advance, installation of a temporary water supply pipe for flushing is facilitated.

Note that as the above-mentioned toilet bowl 102 and temporary hut 104, the parts of a box-shaped temporary toilet used at construction sites, etc., excluding the toilet tank (that is, the toilet bowl and the hut part) can be used as they are. As an example, a flushable temporary toilet (product name: GX-WS or LX-WS) manufactured by Hino Kogyo Co., Ltd. may be used as the toilet bowl 102 and the temporary hut 104.

By using such a toilet bowl 102 and temporary hut 104, it is possible to provide a highly safe and comfortable toilet space that is not easily affected by wind or rain, and where the user's shadow is not reflected by outside lights. In addition, the water seal trap provided in the flush toilet bowl 102 makes it possible to prevent odor from entering the temporary shed 104 from the vertical pipe member 12 and the drain pipe 14, providing a hygienic and comfortable space. can. This will make it possible to reduce the number of disaster victims who do not drink enough water to resist using the toilet at evacuation destinations after a disaster, and to reduce the number of people who develop economy class syndrome. Therefore, it is not just a matter of convenience, but also has an important effect that can be life-threatening for disaster victims. Furthermore, since it can be used during events such as cherry blossom viewing, fireworks displays, and festivals, it can encourage the installation and introduction of System 10 and contribute to the creation of disaster-resistant cities and national resilience.

Moreover, the box-shaped temporary shed 104 does not require assembly work, so installation work is easy. Furthermore, since a toilet tank under the temporary hut 104 is not required, the step at the entrance of the temporary hut 104 can be eliminated, making it barrier-free. However, the materials, shapes, accessories, etc. of the toilet bowl 102 and the temporary hut 104 can be changed as appropriate.

Further, as shown in FIG. 6, when installing the toilet bowl 102 and the temporary shed 104, the deodorizing packing 118 is sandwiched between the upper end opening of the receiving frame of the protective lid 22 and the lower surface of the temporary shed 104. This deodorizing packing 118 prevents the odor in the vertical pipe member 12 and the drain pipe 14 from leaking to the outside through the gap between the lower surface of the temporary hut 104 and the ground surface.

Further, as shown in FIG. 7, a short cylindrical guide member 120 extending to the vertical pipe member 12 is connected to the drain port 102a of the toilet bowl 102. Although the specific configuration of the guide member 120 is not particularly limited, the guide member 120 may be, for example, a synthetic resin pipe connected to the drain port 102a using a thumbscrew 122, as shown in FIG. 7(A). good. Alternatively, for example, as shown in FIG. 7(B), a rubber hose connected to the drain port 102a using a band 124 may be used. With such a guide member 120, waste water from the toilet bowl 102 is smoothly guided into the vertical pipe member 12 without scattering around (that is, without soiling the receiving frame of the protective lid 22).

When the temporary toilet 100 as described above is used and the waste discharged from each toilet bowl 102 accumulates in the vertical pipe member 12, the gate valve of the water tank 18 is opened and the outflow port of the water tank 18 is opened. A predetermined amount of cleaning water is made to flow into the drain pipe 14 from 18a. The timing of opening the gate valve of the water tank 18 and the amount of cleaning water sent from the water tank 18 are adjusted appropriately so that the dirt accumulated in each vertical pipe member 12 can be swept away with a relatively small amount of cleaning water. adjust.

The cleaning water supplied from the water tank 18 to the drain pipe 14 flows down at a predetermined speed within the drain pipe 14 and the lower end portion (horizontal pipe portion 12a) of the vertical pipe member 12. Then, while washing away the filth accumulated in each vertical pipe member 12, the waste is led to the public basin 106 and discharged from the public basin 106 to the sewage main pipe 108. Thereby, the temporary toilet 100 can be used sanitarily.

Note that when the water for flushing supplied from the low tank 112 to the toilet bowls 102 is sufficient, the filth from each toilet bowl 102 is not accumulated in the vertical pipe member 12 and the drain pipe 14, but is led to the public basin 106 and disposed of in the public toilet bowl 102. Since the water is discharged from the basin 106 to the sewer main pipe 108, there is no need for cleaning water to be sent from the water tank 18 to the drain pipe 14.

As described above, according to this embodiment, since the fixing fulcrum 16 is permanently installed, the temporary hut 104 can be easily and firmly fixed. Therefore, the temporary toilet 100 can be easily installed, and the time required to install the temporary toilet 100 can be shortened.

Further, according to this embodiment, even a heavy object such as a box-shaped temporary shed 104 with a lockable door can be firmly fixed, so it can be installed without worrying about it falling over even in strong winds. Therefore, a comfortable temporary toilet 100 can be installed.

In the above-described embodiment, the flushing water supply pipe 116 that supplies flushing water to the toilet bowl 102 is temporarily installed when the system 10 is used. In other words, it can also be left permanently installed.

For example, in the embodiment shown in FIGS. 8 to 10, the water supply pipe 40 for flushing is buried along the drain pipe 14. The upstream side of the water supply pipe 40 for flushing is connected to a water supply pipe (not shown) that is a water supply source, and the water supply pipe 40 for flushing has a water stop at a position upstream of the vertical pipe member 12 on the most upstream side. A plug 42 is provided. The upper part of the water stop valve 42 is covered by a lid body 44 that can be opened and closed. Further, the water supply pipe 40 for flushing branches around each vertical pipe member 12, and a pipe connection portion (toilet side pipe connection portion) 46 is provided there. As the pipe connection part 46, it is preferable to use a threaded joint, a coupler, or the like. Further, a short tube member 48 is provided to form a space around the tube connection portion 46, and a lid (not shown) facing the ground surface is attached to the upper end opening of the tube member 48 so as to be openable and closable. Ru. When used in a disaster or the like, a temporary connecting pipe 126 is connected to the pipe connecting part 46, and the flushing water supply pipe 40 and the low tank 112 are connected via this connecting pipe 126.

By permanently installing the flushing water supply pipe 40 in this manner, the flushing type toilet bowl 102 can be used simply by connecting the flushing water supply pipe 40 and the low tank 112 through the temporary connecting pipe 126. That is, by permanently installing the water supply pipe 40 for flushing, the flush toilet bowl 102 can be easily installed, and the time required to install the temporary toilet 100 can be shortened. Further, since a simple connection method such as a threaded joint or a coupler is used as the pipe connection part 46 of the water supply pipe 40 for flushing, connection and disassembly can be performed even by a person not specialized in water supply.

In addition, as a water supply source of the water supply pipe 40 for flushing, as shown in FIG. 11 and FIG. 12, the water supply tank (water supply tank for water supply pipes) 130 can also be used. In this case, a pipe connection part (water supply source side pipe connection part) 50 such as a threaded joint or a coupler is provided at the upstream end of the water supply pipe 40 for flushing. Further, a rectangular frame-shaped protection member 52 is provided to form a space around the pipe connection portion 50, and a lid (not shown) facing the ground surface is attached to the upper end opening of the protection member 52 so as to be openable and closable. be done. As the water supply tank 130, it is preferable to use, for example, an octagonal cylindrical case made of cardboard with an inner bag made of polyethylene housed inside. When used in the event of a disaster, the water tank 130 is installed on a pedestal 132 so that the water tank 130 is at a higher position than the low tank 112, and the spout of the water tank 130 is connected to the water supply pipe 40 for flushing. 50 are connected via a temporary connecting pipe 134. Then, the water in the water supply tank 130 is supplied to the low tank 112 through the water supply pipe 40 for flushing by gravity due to the height difference.

Moreover, the water supply source of the water supply pipe 40 for flushing can also be made switchable between a water supply pipe and the water supply tank 130, as shown in FIG. In this case, the upstream side of the water supply pipe 40 for flushing is branched into a first pipe part 40a connected to a water pipe (not shown) and a second pipe part 40b connected to the water supply tank 130 via a connecting pipe 134. Ru. A three-way valve (not shown) may be provided at the branching portion between the first pipe section 40a and the second pipe section 40b, or a gate valve may be provided on each of the first pipe section 40a and the second pipe section 40b. Therefore, one of the water supply sources can be selected. In this way, by making it possible to select the water supply source for the water supply pipe 40 for flushing, for example, the water supply tank 130 can be used as the water supply source until the water pipe is restored, and after the water pipe is restored, the water supply source can be changed to the water pipe. Can be used by switching. Therefore, the convenience of the system 10 is improved. When a disaster such as a major earthquake occurs, lifelines such as water, electricity, and gas are shut down, but lifelines are gradually restored after damage is assessed. Those whose homes are affected by the disaster will be forced to live in evacuation centers for a while, but by securing a water supply source to the water tank 130, they will be able to use flush toilets even before the water supply is restored. After the water pipes are restored, by switching the water supply source to the water pipes, water can be supplied to the low tank 112 more quickly, allowing a smooth transition to the familiar flush toilet usage environment.

Furthermore, although not shown, in the same way as the water supply pipe 40 for flushing, electrical wiring (distribution cables) for supplying power to lighting equipment etc. installed in the temporary hut 104 is buried in advance (that is, permanently installed) at the time of construction of the system 10. You can also leave it as is. In this case, it is preferable to bury a protection pipe underground and arrange electric wiring inside the protection pipe. At the tip of the buried electrical wiring, power distribution equipment including an outlet that can be connected to the electrical wiring on the temporary hut 104 side is provided on the ground. This facilitates the installation work of electrical wiring and shortens the time required to install the temporary toilet 100.

Furthermore, as shown in FIG. 14, a waste water storage tank 60 can also be provided on the downstream side of the drain pipe 14. For example, the wastewater storage tank 60 is formed of resin concrete into a substantially rectangular box shape, and the downstream end of the drainpipe 14 is piped so as to pass through the upper part of the wastewater storage tank 60. Furthermore, a pipe joint 62 having a branch pipe portion 62a is incorporated into the drain pipe 14 in a portion passing through the interior of the waste water storage tank 60. Depending on whether or not this branch pipe section 62a is opened, it is possible to select whether to discharge the wastewater as it is into the sewer main pipe 108 or to temporarily store it in the wastewater storage tank 60. By providing such a wastewater storage tank 60, wastewater can be temporarily stored inside the wastewater storage tank 60 even when the main sewage pipe 108 is damaged and cannot be used in the event of a disaster. Therefore, the temporary toilet 100 can be used sanitarily.

Further, in the above embodiment, the protective lid 22 having the iron lid 22a facing the ground surface is provided above the vertical pipe member 12, but the protective lid 22 may be omitted. Although not shown, for example, a substantially disc-shaped synthetic resin lid (vertical pipe lid) is attached to the upper end opening of the vertical pipe member 12, and the vertical pipe is placed so that the lid faces the ground surface. The member 12 can also be buried. In use, when installing the toilet bowl 102 above the vertical pipe member 12, it is only necessary to remove this lid.

Further, in the above embodiment, a Western-style toilet bowl 102 is installed above each vertical pipe member 12, but a Japanese-style toilet bowl can also be installed. Further, the receiving frame of the protective lid 22 can be used as it is as a Japanese-style toilet bowl. Furthermore, it is not necessary to install all of them in Western style or Japanese style; for example, half of them may be Western style and half of them are Japanese style. Further, the toilet bowl 102 may be a flush type, a simple flush type, or a non-flush type. As shown in FIG. 6, since the guide member 120 is accommodated within each vertical pipe member 12, it is possible to connect to any toilet 102 of flush type, simple flush type, or non-flush type.

Further, in the above embodiment, a box-shaped shed having a lockable door 104a is used as the temporary shed 104, but the temporary shed 104 may be of a tent type or a panel assembly type. In other words, the fixing fulcrum 16 can also be used to fix a tent-type or panel assembly-type temporary hut 104. For example, at the beginning of a disaster, a simple non-flushing toilet 102 and a tent-type temporary hut 104 are installed, and if the evacuation becomes prolonged, the above-mentioned flushing toilet 102 and a box-type temporary hut are installed. The temporary hut 104 may be reinstalled.

Furthermore, in the above-mentioned embodiment, a floor drain toilet (S type toilet) having a drain port 102a on the lower side is used as the toilet bowl 102, but the toilet bowl 102 has a drain port 102a on the back side (side). It may also be an above-floor drainage toilet (P-type toilet). As shown in FIGS. 15 and 16, when a P-type toilet bowl is used as the toilet bowl 102, a raised bottom portion 140 is provided on the lower side of the temporary hut 104. The bottom raising part 140 includes a frame 142 and a drainage pipe 144 that guides drainage from the toilet bowl 102 to the vertical pipe member 12. The frame body 142 is formed in a rectangular frame shape along the lower edge of the temporary hut 104, and forms a space of a predetermined height below the temporary hut 104. An opening 142a is formed in the rear side wall of the frame 142, and a drainage pipe 144 is installed to pass through the opening 142a. The drainage pipe 144 is a pipe extending from the rear side wall of the temporary hut 104 to the vertical pipe member 12, and includes a bent pipe part 144a, a horizontal pipe part 144b, and a vertical pipe part 144c. Such drainage piping 144 is preferably pre-processed (prefabricated into a unit) in a factory or the like. Thereby, the installation time and disassembly time of the temporary toilet 100 can be shortened. Further, it is preferable that the horizontal pipe portion 144b of the drain pipe 144 incorporate an expansion joint constituted by a rubber ring socket and a spigot. This makes it possible to adjust the position with respect to the vertical pipe member 12, so that the prefabricated drainage pipe 144 can be applied to various systems 10 in which the diameter and arrangement of the vertical pipe member 12 are different. Note that the frame body 142 and the drainage pipe 144 may be removably integrated in advance.

When installing the toilet bowl 102 and the temporary hut 104 using such a raised bottom part 140, first remove the iron cover 22a and the inner cover of the protective cover 22, and place the frame 142 on the ground above the vertical pipe member 12. Place. Next, the drain pipe 144 is passed through the opening 142a of the frame 142, and with the downstream end of the vertical pipe portion 144c fitted into the upper end of the vertical pipe member 12, the drain pipe 144 is attached using the fixing fitting 146. to be fixed. Subsequently, the temporary hut 104 is placed on the frame 142, and the drain port 102a of the toilet bowl 102 and the upstream end of the curved pipe portion 144a of the drain pipe 144 are connected using a universal joint 148. After that, the temporary hut 104 is fixed by connecting the fixing member 110 that spans the temporary hut 104 to the fixing fulcrum 16. In this way, by using the prefabricated drainage pipe 144, the temporary toilet 100 can be easily installed. Further, the drainage pipe 144 can be used repeatedly, which is useful for environmental conservation.

Further, in the above embodiment, the toilet bowl 102 is fixedly integrated with the bottom plate of the temporary hut 104 in advance, but the toilet bowl 102 is removable from the bottom plate of the temporary hut 104. You can. This facilitates the positioning work of the temporary hut 104 and the piping work of the drain pipe (guide member 120) from the toilet bowl 102 to the vertical pipe member 12. For example, when using an S-shaped toilet bowl as the toilet bowl 102, first, the temporary shed 104 is installed at a predetermined position. At this time, the position of the opening formed in the bottom plate of the temporary hut 104 through which the drain port 102a of the toilet bowl 102 passes is aligned with the position of the vertical pipe member 12. Since the position of the vertical tube member 12 can be visually observed from the opening in the bottom plate, alignment between the opening in the bottom plate and the vertical tube member 12 can be easily performed. On the other hand, a guide member 120 is connected to the drain port 102a of the toilet bowl 102 in advance. Then, by passing the guide member 120 and the drain port 102a through the opening of the bottom plate of the temporary hut 104 and fitting the lower end of the guide member 120 into the upper end of the vertical pipe member 12, the toilet bowl 102 is placed on the bottom plate of the temporary hut 104. Install. Thereafter, the toilet bowl 102 is fixed to the bottom plate using bolts or the like, and the toilet bowl 102 and the low tank 112 are connected. By making the toilet bowl 102 removable from the bottom plate of the temporary hut 104 in this manner, the installation work of the toilet bowl 102 and the temporary hut 104 becomes easy, so that construction can be performed by one worker. In addition, it is preferable to insert deodorizing packing between the lower surface of the toilet bowl 102 and the opening periphery of the bottom plate of the temporary hut 104.

Moreover, when the toilet bowl 102 is made removable from the bottom plate of the temporary hut 104, the position of the toilet bowl 102 with respect to the bottom plate can also be made adjustable. For example, a relatively large opening is formed in the bottom plate of the temporary hut 104. On the other hand, a position adjustment plate is provided on the lower surface side of the toilet bowl 102. The position adjustment plate has an outer shape larger than the opening formed in the bottom plate of the temporary hut 104, and is formed with an opening of a minimum size that communicates with the drain port of the toilet bowl 102. . Note that the position adjustment plate may be detachably attached to the toilet bowl 102, or may be integrally molded. Further, it is preferable to connect a short cylindrical guide member 120 extending to the vertical tube member 12 to the opening of the position adjustment plate. As a result, the toilet bowl 102 can be provided with a position adjustment function, so even if the installation position of the temporary hut 104 deviates from the predetermined position, by adjusting the position of the toilet bowl 102, the position of the guide member 120 can be adjusted vertically. The position of the tube member 12 can be adjusted. Furthermore, if a flexible tube such as a bellows tube or a rubber hose is used as the guide member 120, even if the position of the guide member 120 deviates slightly from the position of the vertical tube member 12, the position deviation will be absorbed. become able to.

Further, in the above embodiment, the bottom plate of the temporary hut 104 is fixedly integrated, but the temporary hut 104 without a bottom plate and the temporary hut 104 may have separate bottom plates. For example, when using an S-shaped toilet as the toilet 102, first, a bottom plate is installed in a predetermined position. At this time, the position of the minimum sized opening formed in the floor plate and communicating with the drain port of the toilet bowl 102 is aligned with the position of the vertical pipe member 12. Then, a temporary hut 104 without a bottom plate is installed at a predetermined position. Then, the toilet bowl 102 is installed on the floor plate by passing the guide member 120 and the drain port 102a through the opening of the floor plate and fitting the lower end of the guide member 120 into the upper end of the vertical pipe member 12. Thereafter, the toilet bowl 102 and the bottom plate are fixed using bolts or the like, and the toilet bowl 102 and the low tank 112 are connected. As described above, by using the temporary hut 104 without a bottom plate and a floor plate, the installation work of the temporary hut 104 is facilitated, so that construction can be performed by one worker. The bottom plate may be larger or smaller than the bottom plate of the temporary hut 104, and the temporary hut 104 may be of a tent type or a panel assembly type.

Furthermore, in the above embodiment, the temporary hut 104 is fixed by the fixing member 110 that is stretched from the fixing fulcrum 16 to the ceiling wall of the temporary hut 104, but in order to more firmly fix the temporary hut 104, Furthermore, the temporary hut 104 may be fixed by winding an auxiliary fixing member such as a rope in the circumferential direction of the temporary hut 104 from the fixing fulcrum 16. Further, as an auxiliary fixing member, a non-slip plate material such as a rubber plate may be provided between the lower surface of the temporary hut 104 and the ground surface. By providing this anti-slip plate material all around the lower surface of the temporary hut 104, it also exhibits a deodorizing function. Furthermore, when the temporary hut 104 has a raised bottom part 140, a support fitting such as an L angle is attached to the receiving frame of the protective lid 22 as an auxiliary fixing member, and the temporary hut 104 is fixed from inside the frame 142 of the raised bottom part 140. You can also. In this way, by providing an auxiliary fixing member for more firmly fixing the temporary hut, it is possible to reliably prevent the temporary hut 104 from shifting laterally even if a strong force is applied from the side of the temporary hut 104. Therefore, the occurrence of disconnection of pipe connections or displacement of pipe positions due to lateral displacement of the temporary hut 104 is eliminated, and problems such as leakage of drainage water are prevented from occurring.

Furthermore, when using a flush toilet bowl 102, the amount of flushing water (discharge amount) supplied to the toilet bowl 102 can be made changeable. As a method of changing the amount of water discharged, for example, it is possible to make the installation position of a ball tap provided in the low tank 112 adjustable. Further, for example, it is possible to adjust the volume of the low tank 112 by putting a balloon in the low tank 112 or by providing a weir inside the low tank 112 and attaching and detaching the weir. By making it possible to change the amount of water discharged into the toilet bowl 102 in this way, it becomes possible to respond to the situation, such as when the water supply is sufficient or insufficient. For example, in the event of a water outage due to a disaster, valuable water can be saved by adjusting the amount of water discharged each time to the minimum necessary. On the other hand, when the water supply is restored, it is advisable to adjust the amount of drainage to the normal amount and provide an environment where drainage can be carried out reliably.

In addition, when using a box-shaped temporary hut 104, a water supply tank (buffer tank) equipped with an intake valve is installed on the ceiling wall (roof) of the temporary hut 104, and water is supplied from the water supply pipe 116 for washing to this tank. The water may be supplied to the low tank 112 via a water supply tank. When a plurality of flush toilets 102 are installed and the amount of water supplied from the flush water supply pipe 116 is insufficient due to intensive use of the toilet, the time required to fill the low tank 112 with water, that is, the waiting time, becomes longer. I end up. On the other hand, by installing a water tank equipped with an intake valve on the ceiling wall of the temporary hut 104, when the water supply pressure from the water supply pipe 116 for flushing drops and there is a water shortage, the water stored in the water tank can be used. Since the water is supplied to the low tank 112 by gravity, waiting time can be reduced.

Further, as a deodorizing measure for the temporary toilet 100, the vertical pipe member 12 may be provided with an odor blocking section such as a flap valve or a self-sealing trap (self-closing membrane) that opens when draining water and is normally sealed. This prevents or suppresses the leakage of odor from the vertical pipe member 12 connected to the sewage main pipe 108 into the toilet space (temporary shed 104) even when using a simple toilet 102 such as a simple flush type or a non-flush type. be able to. Furthermore, it is possible to prevent or suppress mosquitoes from entering the toilet space from the vertical pipe member 12, leading to the prevention of mosquito-borne infectious diseases. Furthermore, since a water-sealing trap for the toilet bowl 102 is not required, further water conservation is possible. Furthermore, even when the system 10 is not in use, leakage of odor from the vertical pipe member 12 to the outside (ground) can be prevented or suppressed. Note that an odor blocker such as a flap valve or a self-sealing trap can also be provided on the guide member 120 connected to the toilet bowl 102 or the position adjustment plate.

Further, the ground to which this system 10 is applied may be a concrete foundation or asphalt, and the term "underground" in this invention includes the inside of concrete or asphalt, and the term "ground surface" refers to the concrete surface. or includes an asphalt surface.

It should be noted that the specific numerical values such as the dimensions and the materials mentioned above are merely examples, and can be changed as appropriate depending on the needs of the product specifications and the like.
