Description

  TECHNICAL FIELD The present invention relates to a temporary toilet system, and more particularly, to a temporary toilet system that is preliminarily constructed in an area serving as an evacuation site in the event of a disaster such as an earthquake, and is used as a temporary toilet when a toilet is attached. .

  When a disaster such as an earthquake occurs, a large number of people may evacuate to an evacuation site such as an elementary school and live there, but if the water supply equipment of the flush toilet is damaged, the toilet will not be usable at that evacuation site There was a thing. Therefore, a technique is known in which a system such as a pipe is constructed in advance in an area that serves as an evacuation site in the event of a disaster, and when a disaster occurs, a toilet or a temporary hut is attached thereto and used as a temporary toilet.

  An example of such a technique is disclosed in Patent Documents 1 and 2.

  In the temporary toilet piping structure of Patent Document 1, manholes are installed at predetermined intervals in the temporary toilet piping disposed in the ground, and a toilet is attached to a rising pipe portion that rises from the manhole. When the toilet is used, the filth is dropped into the manhole, and the filth collected in the manhole is washed down from the pump installed at the uppermost stream of the temporary toilet pipe at regular intervals. It discharges to the water pipe.

Moreover, in the temporary toilet piping apparatus of patent document 2, a vertical pipe is connected to the upper surface of the temporary toilet pipe disposed in the ground at predetermined intervals, and a toilet is attached to the upper part of the vertical pipe. In addition, a storage tank is connected to the most downstream side of the temporary toilet pipe, and initial water is stored in the temporary toilet pipe and the storage tank so that the water level of the drain pipe becomes a predetermined depth. When the toilet is used, the filth dropped from the vertical pipe is diffused into the initial water, and the bottom opening of the storage tank is opened every predetermined time so that the filth is discharged into the existing sewer pipe together with the initial water. ing.

  However, in the technique of Patent Document 1, since the filth collected in the manhole or the temporary toilet pipe is discharged directly to the existing sewer pipe by the cleaning water, the existing sewer pipe is used after being damaged. If it becomes impossible to do so, the filth cannot be washed out.

  Further, in the technique of Patent Document 2, since the initial water mixed with filth is retained in the temporary toilet pipe and the storage tank for a certain period, it is difficult to always keep it hygienic. Moreover, although the pollution degree of initial water changes with the use frequency etc. of a toilet, since it is complicated to confirm the pollution degree suitably, judgment of the timing of washing | cleaning is also difficult.

  Referring to FIGS. 1 and 2, a temporary toilet system 10 (hereinafter simply referred to as “system 10”) according to an embodiment of the present invention includes a school or an evacuation site when a disaster such as an earthquake occurs. A temporary toilet pipe 12 is constructed in the ground of an evacuation area such as a park, and the temporary toilet pipe 12 includes a plurality of manholes 14 and a first drain pipe 16 connected thereto. When a disaster occurs, the system 10 can be used as a temporary toilet by attaching the toilet 18 or the temporary hut 20 to a predetermined position of the temporary toilet pipe 12.

  As shown in FIGS. 1 and 2, the manhole 14 is buried in the ground corresponding to a predetermined installation position of the toilet 18. In FIG. 1 and FIG. 2, five manholes 14 are arranged at equal intervals. However, this is merely an example, and the number of manholes 14 is appropriately changed according to the size of the evacuation area. obtain.

  These five manholes 14 are equivalent to each other, and are, for example, small manholes with ribs made of hard vinyl chloride, and the diameter thereof is, for example, 300 mm. In the following, the five manholes 14 are designated as first, second,..., Fifth manholes in order from the one closer to the water storage tank 76 described later (that is, disposed upstream).

  As shown in FIGS. 3 and 4, the manhole 14 has a hollow cylindrical main body 22, and the main body 22 is configured by joining a main body upper part 22 a and a main body lower part 22 b that can change the joining angle. Is done. Since such a configuration is already well known and is not the gist of the present invention, the details are omitted here. However, in brief, the main body upper portion 22a and the main body lower portion 22b have a predetermined angle with respect to each axis. It is possible to change the joining angle by changing the relative position by rotating the joints through the joint end surfaces inclined at the point.

  An inflow portion 24 and an outflow portion 26 are formed substantially in a straight line along substantially the same tube axis at the lowermost portion of the side wall of the main body portion 22 (the main body lower portion 22b). The inflow portion 24 and the outflow portion 26 have a short cylindrical receiving structure and are formed so as to protrude from the side wall of the main body portion 22, and the upstream or downstream first drain pipe 16 is inserted therein. Rubber rings 28 are attached to the inner surfaces of the inflow portion 24 and the outflow portion 26, and each joint portion is sealed by the rubber ring 28.

  Further, an invert portion 30 having a substantially semicircular cross-sectional shape perpendicular to the tube axis is formed at the bottom of the main body portion 22. The invert part 30 is formed so as to be continuous with the pipe bottoms of the first drain pipes 14 joined to the inflow part 24 and the outflow part 26. That is, the invert part 30 is formed along the flow direction of water.

  Further, a rubber ring receiving port 32 that opens vertically upward is formed at the upper end of the main body 22 (the upper body 22a). A vertical tube 34 rising vertically upward is joined to the rubber ring receiving port 32, and an upper opening of the vertical tube 34 is closed by an inner lid (not shown). The length dimension of the vertical pipe 34 is appropriately adjusted according to the installation depth of the manhole 14, and the length connected to the upstream manhole 14 is made smaller.

  A pedestal 36 is disposed outside (around) the upper end of the vertical tube 34. A receiving frame 38 is placed on the upper surface of the pedestal 36, and an opening of the receiving frame 38 is closed by a protective lid (iron lid) 40. The upper surface of the protective cover 40 faces the ground surface 200.

  In this way, the first to fifth manholes 14 are embedded, and each manhole 14 is connected via the first drain pipe 16. The first drain pipe 16 is disposed with a predetermined downward gradient (for example, about 18/1000), and forms a drain pipe line communicating with the inside of each manhole 14. The first drain pipe 16 is a pipe with a rib made of hard vinyl chloride, for example, and is connected to the inflow portion 24 and the outflow portion 26 of each manhole, and is continuous with the invert portion 30. Each first drain pipe 16 has a length of 2000 mm, for example, and a diameter of 150 mm, for example.

  Returning to FIG. 1 and FIG. 2, a tank 42 is installed on the downstream side of the first drain pipe 16 in the temporary toilet pipe 12 as a storage means capable of storing waste water containing filth collected in each manhole 14. The

  As shown in FIG. 5 and FIG. 6, the tank 42 is formed into a substantially rectangular box shape by, for example, resin concrete, and is used for storing wastewater containing filth collected in each manhole 14 at the time of a disaster or the like. . Further, at times other than disasters (that is, before the tank 42 is used as a drainage storage tank), the internal space is hermetically sealed, and the toilet bowl 18 and the temporary hut 20 described above are installed. It is suitably used as a casing for housing.

  The length (namely, height) of the tank 42 in the vertical direction is, for example, 1500 mm, the width is, for example, 1800 mm, and the depth is, for example, 1000 mm. However, this is merely an example, and the shape and dimensions of the tank 42 can be appropriately changed according to the number of manholes 14, the size of the evacuation area, and the like.

  The tank 42 is connected to the outflow portion 26 of the fifth manhole 14 disposed on the most downstream side via the first drain pipe 16 and connects the existing drain pipe 44 and the second drain pipe 46 leading to the sewage treatment plant. Connected through. The second drain pipe 46 is a pipe that sends the drainage from the first drain pipe 16 to the sewer pipe 44 through the public pit 48, and is formed by appropriately connecting a plurality of straight pipes, flexible pipes, joints, and the like. .

  For example, in this embodiment, the pipe end of the first drain pipe 16 is inserted into the through hole 42b formed at the top of the side wall 42a on the upstream side of the tank 42, and the outer surface of the first drain pipe 16 and the through hole 42b In the meantime, a bonding material 50 such as a water-stopping caulking material or a tough bond (manufactured by Kubota Eye) is filled. Similarly, the pipe end of the second drain pipe 46 is inserted into a through hole 42b formed at a predetermined position lower than the first drain pipe 16 on the side wall 42a on the downstream side of the tank 42. A bonding material 50 is filled between the outer surface of the drain pipe 46 and the through hole 42b.

  Further, a connecting pipe 52 that removably connects the first drain pipe 16 and the second drain pipe 46 is disposed inside the tank 42. The connecting pipe 52 is formed, for example, by connecting straight pipes made of hard vinyl chloride by rubber ring bonding, and is disposed with a gradient substantially equal to that of the first drain pipe 16.

  For example, in this embodiment, as shown in FIG. 7A, the connection pipe 52 is formed by joining the upstream pipe 54 to the rubber ring receiving port 58 at the upstream end of the downstream pipe 56. For this reason, the upstream side pipe 54 and the downstream side pipe 56 are connected with a slight “play”, so the upstream side pipe 54 is connected to the stopper of the rubber ring receiving port 58 (that is, the innermost side). If the size of the “play” at the joint between the upstream side pipe 54 and the downstream side pipe 56 is adjusted by, for example, pushing in, the connecting pipe 52 can be expanded and contracted to adjust its length dimension appropriately. Is possible.

  However, the rubber ring receiving port 58 of the downstream side pipe 56 may have an eccentric receiving structure so that the occurrence of sewage accumulation at the joint between the upstream pipe 54 and the rubber ring receiving port 58 can be reliably prevented.

  Further, flanges 52 a and 52 a are formed at both ends of the connection pipe 52, that is, at the upstream end of the upstream pipe 54 and the downstream end of the downstream pipe 56. A flange 16 a is formed at the downstream pipe end of the first drain pipe 16, and a flange 46 a is formed at the upstream pipe end of the second drain pipe 46. Then, the flanges 52a, 52a at each end of the connecting pipe 52 and the flanges 16a, 46a of the first and second drain pipes 16, 46 are overlapped in the pipe axis direction and fixed with bolts or nuts, thereby connecting pipes. 52 and the first and second drain pipes 16, 46 are detachably flange-joined.

  In the drawing, the flanges 16a and 46a and the flanges 52a and 52a are integrally provided at the pipe ends of the drain pipes 16 and 46 and the connection pipe 52, respectively, but the flanges 16a and 46a and the flanges 52a and 52a are Alternatively, a flange joint or the like separate from the drain pipes 16 and 46 and the connection pipe 52 may be used.

  As described above, the first drain pipe 16 and the second drain pipe 46 are connected by the connecting pipe 52 (to be in the first state), and the first drain pipe 16 and the second drain pipe 46 are communicated with each other. As will be described in detail later, while keeping the water tightness of the tank 42 (that is, with the space inside the tank 42 sealed in a watertight manner), the filth collected in each manhole 14 is removed from the first drain pipe. 16 can be led to the sewer pipe 44 through the second drain pipe 46.

  On the other hand, as shown in FIG. 7B, the connecting pipe 52 is removed from the first drain pipe 16 and the second drain pipe 46 (to the second state), and the first drain pipe 16 and the second drain pipe 46 are As described in detail later, the filth accumulated in each manhole 14 can be guided from the first drain pipe 16 to the internal space of the tank 42.

  5 and 6, the third drain pipe 60 is connected via a gate valve 62 to a predetermined position on the downstream side wall 42 a of the tank 42 and lower than the second drain pipe 46. The The third drain pipe 60 is a pipe that sends the drainage water inside the tank 42 to the sewer pipe 44 through the public tub 64, and is formed by appropriately connecting a plurality of straight pipes, flexible pipes, joints, and the like. Similarly to the first and second drain pipes 16 and 46, the third drain pipe 60 is inserted into the through hole 42b formed in the side wall 42a of the tank 42, and the bonding material 50 is provided between the outer surface and the through hole 42b. Is filled.

  The gate valve 62 is a gate valve provided on the inner surface side of the side wall 42 a of the tank 42, and opens and closes the flow path at the connection portion between the third drain pipe 60 and the tank 40, and is stored in the tank 42. In order to keep the accumulated drainage in the tank 42 by sealing the pipe end on the upstream side of the third drainage pipe 60 at other times. Closed. For example, a known electromagnetic valve or the like can be used as the gate valve 62 and is electrically controlled to be opened / closed. Alternatively, an operator may manually open / close the tank 42. .

  Furthermore, an inspection portion 66 that protrudes vertically upward is formed on the upper surface of the tank 42. The inspection unit 66 is located at a position where it does not overlap with the connecting pipe 52 in plan view so that the connecting pipe 52 does not get in the way when in use (that is, when the toilet 18 or the temporary hut 20 is carried out of the tank 42). In this embodiment, it is formed at a predetermined position on the back side of the connection pipe 52.

  As shown in FIGS. 5 and 7A, the lower opening of the inspection portion 66 is closed by an inner lid 70 via a rubber ring 68, and the water tightness of the tank 42 is maintained. Further, the upper opening of the inspection unit 66 is closed by an iron lid (protective lid) 72, and the upper surface of the iron lid 72 faces the ground surface 200. In addition, on the inner side of the side wall 42 a of the tank 42, a lifting step 74 is provided at a predetermined position corresponding to the inspection unit 66.

  Returning to FIG. 1 and FIG. 2, a water storage tank 76 is provided as water supply means for sending cleaning water for the temporary toilet to the upstream side of the first drain pipe 16 upstream of the first drain pipe 16 of the temporary toilet pipe 12. Is installed.

  The water storage tank 76 is connected to the first drain pipe 16 connected to the inflow portion 24 of the first manhole 14 disposed on the most upstream side via a gate valve 78. For example, water is supplied to the water storage tank 76 from a water supply pump (not shown). As shown in FIG. 8, the water stored in the water storage tank 76 is supplied from the water injection port 76a formed in the lower part to the first water supply port 76a. It flows into the pipe end on the upstream side of the drain pipe 16.

  As the water storage tank 76, a general-purpose water tank made of synthetic resin can be used, and its height is, for example, 800 mm, its width is, for example, 450 mm, and its depth is, for example, 450 mm. However, this is merely an example, and the shape and size of the water storage tank 76 can be changed as appropriate according to the number of manholes 14, the size of the evacuation area, and the like.

  An inspection port 76 b is formed on the upper surface of the water storage tank 76. The inspection port 76 b is closed with a lid 80, and the upper surface of the lid 80 faces the ground surface 200. The inspection port 76 b is used as a water supply port to the inside of the water storage tank 76.

  The gate valve 78 is opened when the water accumulated in the water storage tank 76 is sent to the upstream side of the first drain pipe 16, and at other times, the water injection port 76 a is sealed to supply the water inside the water storage tank 70. The gate valve is provided on the inner surface side of the water storage tank 70. A known electromagnetic valve or the like can be used as the gate valve 78 and is electrically controlled to be opened and closed. Alternatively, an operator may manually open and close the gate valve 78.

In this embodiment, the rainwater collected in the rainwater storage tank 82 is pumped up (taken in) by the water supply pump, and then supplied to the water storage tank 66 to be used as cleaning water for the temporary toilet. Yes.

  Here, the rainwater storage tank 82 will be briefly described. The rainwater storage tank 82 mainly collects rainwater, temporarily stores the collected rainwater, and then mainly uses it effectively as cleaning water for a temporary toilet at the time of a disaster. It is buried as a purpose. Specifically, as the rainwater storage tank 82, for example, various rainwater storage tanks manufactured and sold by the applicant of the present application (see; http://www.kubota-ci.co.jp/products/sewage/ rain.html). Moreover, it is not necessary to be limited to this, and various conventionally known rainwater storage tanks can be adopted regardless of the material (made of synthetic resin, concrete, etc.) or shape.

  For example, in this embodiment, unit tanks 86 in which plastic element members 84 as shown in FIG. 9 are combined in the vertical direction are arranged side by side along the manholes 14 and the first drain pipes 16. The basic shape of the rainwater storage tank 82 as shown in FIG. 2 is comprised, and the circumference | surroundings are covered with a water shielding sheet (not shown).

  In addition, the assembly-type rainwater storage tank using such an element member 84 is described in detail in Japanese Patent Application Laid-Open No. 2009-138354 filed earlier by the applicant of the present application. Please refer.

  Moreover, as shown in FIG. 10, the rainwater storage tank 82 is provided with a water intake portion 88 for taking out the accumulated rainwater. The water intake section 88 is provided at a position lower than the unit tank 86 (that is, below) so that the water accumulated in the rainwater storage tank 82 can be taken out without waste. For example, in this embodiment, the rainwater Another unit tank 86 is installed below the unit tank 86 on the most upstream side of the storage tank 82, and the unit tank 86 is used as the water unit 88. By doing so, the water accumulated in the rainwater storage tank 82 is automatically collected in the water intake unit tank 86 when water is pumped up.

  Further, the water intake section 88 is provided with a water intake pipe 90 for pumping up (collects) collected water. The water intake pipe 90 is disposed so as to penetrate the water intake part 88 (unit tank 86 used as) and the unit tank 86 thereabove, and the lower end thereof opens at the bottom of the water intake part 88. Further, the upper end portion of the intake pipe 90 is closed by a lid 92, and a pedestal 94 is disposed on the outside (periphery) of the lid 92. A receiving frame 96 is placed on the upper surface of the pedestal 94, and an opening of the receiving frame 96 is closed by an iron lid (protective lid) 98. And the upper surface of the iron lid 98 faces the ground surface 200.

  By constructing such a system 10 in the ground of an evacuation site in advance of a disaster, a temporary toilet can be quickly and easily installed when a disaster occurs. When the system 10 is used as a temporary toilet, first, equipment such as the toilet 18 and the temporary hut 20 is carried out from the inside of the tank 42, and then the protective lid 40 on the upper part of each manhole 14 is removed, and the toilet is placed there. 18 and a temporary hut 20 are installed so as to surround each toilet 18.

  Note that one of the particularly important points in the system 10 is a mechanism for selecting a treatment destination of the filth accumulated in each manhole 14. Therefore, in the following, a method for treating filth collected in each manhole 14 in a normal time when the sewage pipe 44 can be used will be described in detail among methods using a temporary toilet using the system 10.

  First, cleaning water for cleaning (scavenging) the dirt accumulated in each manhole 14 is supplied to the water storage tank 76.

  Specifically, first, a water supply pump (not shown) is prepared on the ground of the construction area. Subsequently, the lid 92 and the iron lid 98 of the water intake pipe 90 are removed, and the cover 80 of the inspection port 76b of the water storage tank 76 is removed, and the water intake pipe 90 is connected to the rain water stored in the rain water storage tank 82 from the water intake section 88. The water is pumped up (taken in) by the water supply pump, and the rainwater is supplied into the water storage tank 76. However, water supplied from other water supply sources (wells, pools, tap water, etc.) may be supplied to the water storage tank 76 together with or instead of the rainwater taken from the rainwater storage tank 82.

  Then, the gate valve 72 is opened at an appropriate timing, and a predetermined amount of water in the water in the water storage tank 76 is allowed to flow from the water injection port 76 a to the upstream pipe end of the first drain pipe 16. The timing for opening the gate valve 72 and the amount of water fed from the water storage tank 76 are adjusted as appropriate so that the filth collected in each manhole 14 can be swept away using relatively little water.

  Then, the water sent from the water storage tank 76 flows down the first drain pipe 16 embedded at a predetermined gradient at a predetermined speed, and is connected from the first drain pipe 16 as shown in FIG. The water is guided to the sewer pipe 44 through the pipe 52 and the second drain pipe 46. At this time, the filth collected in each manhole 14 is discharged to the sewer pipe 44 together with the flowing water.

  At this time, since the first drain pipe 16 and the second drain pipe 46 are connected by the connecting pipe 52, the first drain pipe 16 and the second drain pipe 46 and the space inside the tank 42 communicate with each other. No, the water tightness of the tank 42 is maintained.

  Next, a specific description will be given of a method for treating the filth collected in each manhole 14 when the sewer pipe 44 becomes unusable (not functioning) due to damage or the like.

  First, the connection pipe 52 is removed from the first and second drain pipes 16 and 46 before the use of the temporary toilet is started. When the connecting pipe 52 is removed from the first and second drain pipes 16, 46, the flanges 52a, 52a at each end of the connecting pipe 52 and the flanges 16a, 46a of the first and second drain pipes 16, 46 are flanged. In addition to releasing the connection, the length of the connecting pipe 52 is reduced (shortened) by pushing the upstream pipe 54 into the back side of the rubber ring receiving port 58 of the downstream pipe 56, and the removed connecting pipe 52 is inspected. 66 to move outside the tank 42.

  Then, in the same manner as described above, cleaning water for cleaning the filth accumulated in each manhole 14 is supplied to the water storage tank 76, the gate valve 72 is opened at an appropriate timing, and the water in the water storage tank 76 is supplied. Into the pipe end on the upstream side of the first drain pipe 16.

  Then, the water fed from the water storage tank 76 flows down the first drain pipe 16 embedded at a predetermined gradient at a predetermined speed, and as shown in FIG. It is led into the inside of the tank 42 from the downstream pipe end. At this time, the filth collected in each manhole 14 is discharged into the tank 42 together with the flowing water, and is stored in the tank 42 as it is.

  Thereafter, when the sewer pipe 44 is restored, the gate valve 62 is opened, so that the waste water stored in the tank 42 flows into the third drain pipe 60 as shown in FIG. It discharges from the pipe 60 to the sewer pipe 44. At this time, since the third drain pipe 60 and the gate valve 62 are provided not on the bottom of the tank 42 but on the side wall 42 of the tank 42, a large amount of waste water is stored in the tank 42. Even in such a case, the gate valve 62 can be easily opened, and the drainage can be discharged from the third drainage pipe 60 to the sewer pipe 44.

  However, instead of discharging the wastewater stored in the tank 42 from the third drain pipe 60 to the sewer pipe 44, a suction hose of a vacuum car or the like is inserted into the tank 42 from the inspection section 66, You may make it collect | recover in the collection tank of a vacuum car, etc. with a suction hose.

  As described above, according to the system 10 of this embodiment, whether wastewater containing filth collected in each manhole 14 is discharged to the sewer pipe 44 or stored inside the tank 42 depends on the situation of the sewer pipe 44. Can be selected.

  That is, when the sewer pipe 44 can be used, the first drain pipe 16 and the second drain pipe 46 are connected by the connection pipe 52 so that the first drain pipe 16 and the second drain pipe 46 are communicated with each other. Since the waste water containing the filth collected in each manhole 16 can be discharged directly to the sewer pipe 44, the drain water is swept into the sewer pipe 44 every time water is sent from the water storage tank 76, and the temporary toilet is installed. It is possible to keep it hygienic.

  On the other hand, when the sewage pipe 44 cannot be used, the connection pipe 52 is removed from the first drain pipe 16 and the second drain pipe 46 and the first drain pipe 16 and the second drain pipe 46 are separated. Thus, the wastewater containing the filth collected in each manhole 14 can be discharged into the tank 42 and temporarily stored in the tank 42. Then, the wastewater stored in the tank 42 can be discharged to the sewer pipe 44 after the sewer pipe 44 is restored. Therefore, even if the sewage pipe 44 is damaged, a temporary toilet can be used, and the drainage is not stored in the toilet portion but is stored in the tank 42 on the downstream side of each manhole 14. As a result, users of temporary toilets do not feel unpleasant about odor leaks.

  Therefore, according to the system 10 of this embodiment, it is possible to provide a temporary toilet that can be used comfortably and can be kept hygienic even if the sewer pipe 44 is damaged.

  Further, in this embodiment, a rainwater storage tank 82 is installed in the construction area of the system 10, rainwater collected in the rainwater storage tank 82 is supplied to the water supply tank 76, and the water is stored in each manhole 14. It is used as cleaning water for filth. For this reason, even if water pipes cannot be supplied due to damage to water pipes, or even when water sources such as wells and pools do not exist in the vicinity of the construction area of the system 10, the inside of each manhole 14 This makes it possible to secure cleaning water for scavenging the filth collected in the tub and keep the temporary toilet hygienic.

  Furthermore, in this embodiment, the tank 42 for temporarily storing the wastewater is also used as a casing for storing equipment such as the toilet 18 and the temporary hut 20.

  Here, conventionally, a storage room for storing equipment such as the toilet bowl 18 and the temporary hut 20 is installed in the vicinity of the temporary toilet pipe 12 so that a temporary toilet can be quickly installed in the event of a disaster. It was necessary to keep. When the storage is collapsed due to a disaster or the like, the temporary toilet equipment cannot be carried out, and the temporary toilet may not be used. However, according to this embodiment, since the tank 42 of the system 10 is also used as a casing for housing the toilet bowl 18 and the temporary shed 20, even the system 10 can function without being damaged. For example, a temporary toilet can be used. That is, the system 10 can be completed by itself.

  In particular, in this embodiment, since the tank 42 is formed of resin concrete, water tightness can be ensured in the tank 42, and in a state before selecting the inside of the tank 42 as a wastewater treatment destination, Since the internal space of the tank 42 is hermetically sealed, the inside of the tank 42 can be kept dry. Therefore, fixtures such as the toilet bowl 18 and the temporary hut 20 can be stored permanently and appropriately.

  In this embodiment, the flanges 52a and 52a at the end portions of the connecting pipe 52 and the flanges 16a and 46a of the first and second drain pipes 16 and 46 are flange-joined, whereby the first and second drains. The pipes 16 and 46 and the connecting pipe 52 are joined. By flange joining in this way, it is possible to attach and detach the first and second drain pipes 16 and 46 without moving the connecting pipe 52 in the pipe axis direction.

  Further, the connecting pipe 52 is formed by joining the upstream pipe 54 to the rubber ring receiving port 58 of the downstream pipe 56. For this reason, the upstream side pipe 54 and the downstream side pipe 56 are connected with a certain amount of “play”. Therefore, the connection pipe 52 can be expanded and contracted by adjusting the dimension of the “play”. Is possible.

  Therefore, when the flanges 52a and 52a at the ends of the connecting pipe 52 and the flanges 16a and 46a of the first and second drain pipes 16 and 46 are flange-bonded, the upstream pipe 54 is connected to the downstream pipe 56, for example. When the rubber ring receiving port 58 is pushed in to the stopper (that is, the innermost side), the “play” is temporarily removed and placed at a predetermined position and returned to the predetermined position, the attachment work of the connecting pipe 52 is facilitated. Become.

  Further, after releasing the flange joint between the flanges 52a, 52a at each end of the connecting pipe 52 and the flanges 16a, 46a of the first and second drain pipes 16, 46, the upstream pipe 54 is connected to the downstream pipe. If the "play" is eliminated once by pushing the stopper of the rubber ring receiving port 58, the connecting pipe 52 can be easily removed.

  Therefore, according to this embodiment, it is possible to easily perform the attaching / detaching operation of the connecting pipe 52 even in a limited space inside the tank 42.

  In the above-described embodiment, the water taken from the rainwater storage tank 78 and other water sources by the water supply pump is supplied to the water storage tank 76, and the water is sent from the water storage tank 76 to the first drain pipe 16. It is not necessary to be limited to this, and the water taken by the water supply pump may be sent directly to the first drain pipe 16.

  In that case, as an example, the water supply pump is set to be driven for a preset time every time a predetermined time elapses or when a predetermined time is reached by being electrically controlled. The Moreover, the time interval, drive time, etc. which drive a water supply pump are suitably set so that the filth collected in each manhole 14 can be swept away using comparatively little water.

  Further, the opening and closing of the gate valve 72 is interlocked with the driving of the feed water pump, so that the gate valve 72 is automatically opened when the feed water pump is driven, and the gate valve 72 is automatically closed when the feed water pump is stopped. You may make it do.

  Furthermore, the water may be automatically supplied into the water storage tank 76 by a water supply pump when the water in the water storage tank 76 becomes below a predetermined lower limit water level. For example, the lower limit water level of the water storage tank 76 is detected by a water level detector or the like. Alternatively, a person may visually check the water level of the water storage tank 76 and manually drive the water supply pump at an arbitrary timing to supply water into the water storage tank 76.

  Furthermore, in the above-described embodiment, the unit tanks 86 in which the element members 84 are combined in the vertical direction are arranged side by side along the manholes 14 and the first drain pipes 16, and below the uppermost unit tank 86. Although the rainwater storage tank 78 was formed by providing the water intake part 88, it is not necessary to be limited to this. The shape, size, and installation location of the rainwater storage tank 78 are merely examples, and they can be changed as appropriate according to the shape and size of an empty space in the construction area of the system 10.

  Furthermore, it is not always necessary to install the rainwater storage tank 78 in the construction area of the system 10. For example, in the system 10 that is another embodiment of the present invention shown in FIGS. 13 and 14, unlike the embodiment shown in FIG. 1, the rainwater storage tank 78 is not installed in the construction area of the system 10.

  In the temporary toilet using the system 10 shown in FIGS. 13 and 14, water taken from other water sources such as tap water and wells and pools is supplied to the water storage tank 76 when the filth collected in each manhole 14 is treated. In addition, the water is used as cleaning water for filth.

  Furthermore, it is not always necessary to provide the third drain pipe 60 for sending the waste water inside the tank 42 to the sewage pipe 44, and the third drain pipe 60 and the gate are provided in the tank 42 as in the system 10 shown in FIGS. 13 and 14. The valve 62 may not be provided. In a temporary toilet using such a system 10, when processing the wastewater temporarily stored in the tank 42, a suction hose of a vacuum car or the like is inserted into the tank 42 from the inspection unit 66, and the suction hose is used for vacuuming. Collect in the car's collection tank.

  Further, in each of the above-described embodiments, in the temporary toilet pipe 12, the manholes 14 and the first drain pipes 16 are disposed with substantially the same gradient along the same straight line. However, the present invention is not limited to this. It is not necessary to form a flow accelerating portion such as a step between the upstream side and the downstream side in a part of the first drain pipe 16.

  Furthermore, in each of the above-described embodiments, a ribbed pipe is used as the first drain pipe 16, but instead of this, a cylindrical pipe having no rib may be used. And although the small manhole with a rib was used as the manhole 14, it may replace with this and may use the small manhole in which the rib is not formed.

  In each of the above-described embodiments, the flanges 52a and 52a at the end portions of the connection pipe 52 and the flanges 16a and 46a of the first and second drain pipes 16 and 46 are flange-joined to each other. Although the second drain pipes 16 and 46 and the connection pipe 52 are connected, it is not necessary to be limited to this. For example, although not shown, the first and second drain pipes 16 and 46 and the connection pipe 52 may be connected via a joint having an expansion / contraction mechanism such as an exchange joint or a dresser joint. Even in this case, the attachment / detachment work of the connecting pipe 52 can be easily performed by adjusting the length at the joint portion.

  Further, in each of the above-described embodiments, the first and second drain pipes 16 and 46 are inserted into the through hole 42b of the side wall 42a of the tank 42, and the through hole 42b and the first and second drain pipes 16, The first and second drain pipes 16 and 46 are connected to the tank 42 by filling the bonding material 50 between the outer surface of the tank 46, but the first and second drain pipes 16 and 46 need not be limited to this. As long as the second drain pipes 16 and 46 can be connected in a watertight manner, the connection method of the first and second drain pipes 16 and 46 to the tank 42 can be changed as appropriate.

  For example, instead of the bonding material 50, a sealing material such as water expansion rubber may be provided between the through hole 42 b and the outer surfaces of the first and second drain pipes 16 and 46. By doing so, the water tightness of the tank 42 can be improved.

  As shown in FIG. 15, a rubber manhole joint 100 is fixedly provided in the through hole 42 b of the side wall 42 a of the tank 42, and the first and second drain pipes 16 and 46 are respectively provided at one end of the manhole joint 100. And a flange short pipe 102 having a flange 102a at the other end is connected, and the flanges 52a, 52a at each end of the connection pipe 52 and the flanges 102a, 102a of each flange short pipe 102 are flange-joined. It may be.

  By doing in this way, a water stop can be ensured in the connection part of the 1st and 2nd drain pipes 16 and 46 and the tank 42, and the water-tightness of the tank 42 can be improved. Further, even when an external force is applied to the connecting portion between the first and second drain pipes 16 and 46 and the tank 42 due to an earthquake or the like, there arises a problem that the bonding material 50 is broken and the water stoppage is lost, for example. It will disappear.

  In addition, although illustration is abbreviate | omitted, you may make it connect the 3rd drainage pipe 60 to the tank 42 via the manhole joint 100 similarly to the 1st and 2nd drainage pipes 16 and 46. FIG.

  In each of the above-described embodiments, the connection pipe 52 is formed by joining the upstream pipe 54 to the rubber ring receiving port 58 of the downstream pipe 56 with some “play”. It is not necessary to be limited to this. As the connecting pipe 52, for example, a straight pipe made of hard vinyl chloride may be used.

  Further, in each of the above-described embodiments, the wastewater treatment destination is selected by attaching / detaching the connecting pipe 52. That is, although the connection pipe 52 is used as a selection means for selecting a wastewater treatment destination, it is not necessary to be limited to this.

  For example, the connection pipe 52 is not necessarily provided. As an example, although illustration is omitted, a gate valve is provided at a connection portion between the first drain pipe 16 and the tank 42 and a connection portion between the second drain pipe 46 and the tank 42, and these gate valves are used as selection means. Then, it may be selected whether the drainage is stored in the tank 42 or guided from the second drainage pipe 46 to the sewer pipe 44. Even in this case, the internal space of the tank 42 can be watertightly sealed before the gate valve is opened.

  Further, the drainage flowing from the first drainage pipe 16 is stored in the tank 42 or discharged from the third drainage pipe 60 to the sewer pipe 42 by opening and closing the gate valve 62 without necessarily providing the second drainage pipe 46. You may make it select whether to do. In this case, the third drain pipe 60 functions as a second drain pipe.

  Furthermore, in each of the above-described embodiments, the gate valve 62 is provided inside the tank 42 (on the inner surface side of the side wall 42a), and the gate valve 62 is electrically controlled to open or close, or an operator can manually operate inside the tank 42. Although the gate valve 62 is opened and closed, the present invention is not limited to this. For example, in the system 10 which is another embodiment of the present invention shown in FIGS. 16 and 17, unlike the embodiment shown in FIG. 1, by operating the handle 62a for controlling opening and closing of the gate valve 62 on the ground, The gate valve 62 is opened and closed.

  In the embodiment shown in FIGS. 16 and 17, a through hole 42 d is formed in the top surface 42 c of the tank 42. A pedestal 104 is provided above the top surface 42c of the tank 42 and around the through hole 42d. A valve (valve box) 106 is placed on the upper surface of the pedestal 104, and the upper opening of the valve 106 is closed by a lid 108. Note that the upper surface of the lid 108 of the valve 106 faces the ground surface 200.

  Further, the gate valve 62 is installed inside the tank 42 (on the inner surface side of the side wall 42a). A handle 62 a that controls the opening and closing of the gate valve 62 extends vertically upward from the installation position of the gate valve 62, is inserted into the through hole 42 d, and is disposed inside the valve casing 106. Between the extended part of the handle 62a of the gate valve 62 and the through hole 42d, a sealing material 110 such as water expansion rubber is provided so that the water tightness of the tank 42 is maintained.

  In such a system 10, the gate valve 62 can be opened and closed by the operator removing the lid 108 of the valve 106 and operating the handle 62 a on the ground, so that power such as electricity is not required for the gate valve 62. become.

  In addition, for example, a trapezoidal manhole flexible joint or universal joint having earthquake resistance is used for the connecting portion between the manhole 14 and the first drain pipe 16 and the connecting portion between each drain pipe 16, 46, 56 and the tank 42. May be.

  Further, a check valve such as a flap valve may be provided at the connecting portion between the first drain pipe 16 and the tank 42 so that odor leakage can be prevented. In particular, when the drainage is temporarily stored in the tank 42 without using the sewage pipe 44, the use of the temporary toilet is started after the connection pipe 52 is removed from the first and second drainage pipes 16 and 46. It is preferable to provide a check valve at the pipe end portion downstream of the first drain pipe 16 in advance so that the user of the temporary toilet can be prevented from feeling unpleasant odor leakage.

  Furthermore, you may make it provide the backflow prevention valve which prevents drainage from flowing backward in the connection part of each drainage pipe 16,46,56 and the tank 42. FIG.

  Further, in each of the above-described embodiments, the manhole 14 is buried in the ground corresponding to a predetermined installation position of the toilet 18, but it is not necessary to be limited to this. The manhole 14 is merely an example, and instead of the manhole 14, a cheese joint is connected to the first drain pipe 16, and a vertical pipe is raised from the cheese joint, or a saddle joint is connected to the first drain pipe 16, A vertical pipe may be raised from the saddle joint. In short, it is only necessary that a vertical tubular member (longitudinal tube member) is disposed in the ground where the toilet 18 is set in advance. Preferably, the upper opening of each vertical pipe member is closed with an inner lid so that water can be prevented from entering the first drain pipe 16.

  Further, in the above-described embodiments, the toilet bowl 18 is illustrated as using a Western style toilet bowl. However, the present invention is not limited to this, and a Japanese style toilet bowl may be used. Needless to say.

  It should be noted that the specific numerical values such as the dimensions described above are merely examples, and can be appropriately changed according to the needs of product specifications and the like.
