Description

  The present invention relates to a toilet system including a manhole cover and a toilet placed on the cover.

  After the occurrence of a disaster such as a major earthquake or fire, problems such as damage to water and sewer pipes buried underground, inability to use toilets due to water outages, and lack of toilets due to collapse of buildings such as houses and buildings, Many people have to endure defecation until the date of recovery. Therefore, toilet measures that provide toilets immediately after a disaster occurs are indispensable as disaster measures.

A manhole toilet or the like that diverts an existing manhole cover to a toilet has been proposed (see Non-Patent Document 1).

  However, in the event of a major earthquake, there is a high possibility that the road will be closed due to the closure of the road, etc., so that it is stocked at a predetermined place in normal times, and the simple toilet that needs to be transported to the disaster occurrence area when a disaster occurs, The built-in toilet and the in-vehicle toilet are not effective.

  In addition, although the underground buried toilet and the existing facility diversion toilet do not require transportation to the disaster-occurring area, human feces are stored in a certain space. There is a risk that the amount of human feces stored will exceed the limit.

  On the other hand, in the case of the manhole toilet, human feces are flushed by sewage connected to the manhole in addition to using familiar facilities, so this is an excellent toilet measure with virtually no limit on the amount of human feces stored.

However, during the Great Hanshin Earthquake in 1995, problems with the manhole toilet were revealed. In other words, many people use the manhole toilet over a long period of time due to drastic reduction in the amount of sewage due to a water outage, so that excreted human feces are not flowed into the sewage but piled up at the bottom of the sewage channel is there. Such problems have resulted in further exposure of disaster victims to odors and unsanitary environments.

  In FIG. 1, reference numeral 50 denotes a manhole connected to a sewer, which is covered with a lid body 40. The toilet 30 is disposed on the surface of the lid 40, and the toilet 30 and the user of the toilet 30 are covered with the blindfold member 20. A water source 10 is installed within a radius of 10 m from the manhole 50, for example, and rainwater is stored in the water source 10.

  FIG. 2 is a partially broken longitudinal sectional view schematically showing the water source 10 according to the toilet system of the present invention. The water source 10 is installed on the ground.

  A plurality of rain water storage tanks 1, 1,... Having a rectangular parallelepiped shape whose upper surface is open are connected horizontally by connecting pipes 2, 2, ... on crushed stone / river sand 15 laid on the ground or concrete surface. It is placed in the state. On the rainwater storage tanks 1, 1,..., Rectangular plate-like interval holding members 5, 5,. In this embodiment, a pallet on which a load is placed when the load is transported by a forklift is diverted as the spacing members 5, 5,.

  The non-woven fabric 13 is placed on the spacing members 5, 5,..., And the spacing members 5, 5,. The soil layer 14 is planted with turf 12 and flowers 11. A rain water storage type greening device 17 composed of rain water storage tanks 1, 1,..., Spacing members 5, 5,. Yes.

  The soil layer 14 is decomposed and becomes nutrients of the turf 12 and the flower 11 and also absorbs moisture evaporated from rainwater (hereinafter referred to as “reserved water”) stored in the rainwater storage tanks 1, 1. 19 and charcoal which mainly serves to adsorb evaporated water. The decay chip 19 is disposed below the soil layer 14 and charcoal is mixed with soil.

  A cylindrical hose connecting portion 18 is provided at a predetermined position below the earth retaining member 16 to drain the stored water in the rainwater storage tanks 1, 1,. One end portion of the hose connecting portion 18 penetrates the customer soil layer 14 interposed between the rainwater storage tanks 1, 1,... It is connected to the connecting pipe attachment hole 3 at the lower end of one rainwater storage tank 1 arranged on the 16 side. The other end of the hose connecting portion 18 is normally closed with a stopper (not shown), but is connected to a hose 52 described later in the event of a disaster.

FIG. 3 is a perspective view showing the rainwater storage tank 1. The rainwater storage tanks 1, 1,... Are made of polypropylene, and are, for example, rectangular parallelepiped boxes having a vertical width of 592 mm, a horizontal width of 455 mm, and a height of 354 mm, and the upper surface is open. In this embodiment, the volume is 0.095 ^3, it is possible to store the rainwater 0.592m ³ / m ² at full water. A plurality of reinforcing ribs 4a, 4a,... Having a length slightly shorter than the height of the rainwater storage tanks 1, 1,. Are arranged side by side in the height direction. In addition, two reinforcing ribs 4b, 4b whose length is equal to the vertical width of the rainwater storage tanks 1, 1,... Are provided with two reinforcing ribs 4c, 4c equal in width to the rainwater storage tanks 1, 1,.

  In addition, connecting pipe mounting holes 3 and 3 into which the connecting pipe 2 is fitted are respectively provided at the centers of the lower ends of the side surfaces on both short sides of the rainwater storage tanks 1, 1. Therefore, according to the installation area of the water source 10, the number and arrangement | positioning of several rainwater storage tank 1,1, ... can be changed.

  FIG. 4 is a perspective view showing the spacing member 5. The spacing member 5 is made of polypropylene and has a rectangular plate shape. Two rectangular cross-section cavities 6 and 6 penetrating the interval holding member 5 in the longitudinal direction are provided on the short side of the interval holding member 5 as appropriate. On the long side of the spacing member 5, two rectangular sections 7 and 7 penetrating the spacing member 5 in the width direction are provided as appropriate. The cavities 6 and 6 and the cavities 7 and 7 communicate with each other inside the spacing member 5.

  The spacing member 5 is provided with mesh-like ventilation / water passages 6a, 6a on the upper side of the cavities 6, 6, and ventilation / water passages 6b, 6b on the lower side. Further, mesh-like ventilation / water passages 7a, 7a are provided above the hollow portions 7, 7, and ventilation / water passages 7b, 7b are provided below. Therefore, the space | interval holding | maintenance member 5 goes up and down via the cavity parts 6 and 6 and ventilation / water flow path 6a, 6a, 6b, 6b and the cavity parts 7 and 7 and ventilation / water flow path 7a, 7a, 7b, 7b. Air and moisture move.

  Next, a method for manufacturing the decayed chip 19 to be blended in the soil layer 14 will be described. First, wood such as pruning material is cut into chips having a diameter of 4 to 15 mm and a length of 30 to 100 mm. It is preferable to mix 10 to 35 parts by mass of rice bran as a moisture adjusting agent and 10 to 35 parts by mass of nitrogen fertilizer as a decomposition accelerator with respect to 100 parts by mass of the cut wood chips, and 15 to 15 parts of rice bran. More preferably, 20 parts by mass and 15 to 20 parts by mass of nitrogen fertilizer are mixed. Lime nitrogen is preferably used as the nitrogen fertilizer, and the target CN ratio (ratio of carbon content to nitrogen content) is set to 30. On the other hand, when the ratio of rice bran is less than 10 parts by mass and the ratio of nitrogen fertilizer is less than 10 parts by mass, the decayed chips 19 cannot be obtained in a short time. Moreover, when the ratio of rice bran exceeds 35 parts by mass and the ratio of nitrogen fertilizer exceeds 30 parts by mass, the decayed chips 19 having good water retention cannot be obtained because the fermentation proceeds too much.

  It is preferable to adjust the moisture of the wood chip to about 50 to 55%. When an overdried wood chip is used, the function of the fermentation accelerator is lowered, causing variation during the decay period, and causing the growth of spoilage bacteria due to poor fermentation, resulting in fermentation failure. On the other hand, when there is much water, anaerobic bacteria may increase and it may rot.

  The mixture of wood chips, rice bran and nitrogen fertilizer needs to be adequately oxygenated during the fermentation period, while the air needs to be adequately shut off to retain the heat of fermentation associated with microbial degradation. Therefore, it is preferable to stir the mixture once a day for 5-7 days to inject air.

  Heat is generated when fermenting bacteria propagate. In this case, the temperature is about 60 to 70 ° C., and eggs of pathogenic bacteria and parasites, seeds of weeds and the like are killed. In order to efficiently proliferate fermenting bacteria, it is necessary to maintain the above temperature, and by adding rice bran, nitrogen fertilizer, etc. as necessary, heat is taken away from the surroundings and the temperature decreases. prevent.

  When the heat rises, so-called “turning back” is performed by stirring the mixture. Thereby, supply of oxygen and adjustment of moisture are made, and fermentation decomposition is promoted. If no rapid heat rise is observed after “turning back”, it is determined that decay has been completed.

  According to this manufacturing method, since the pH is low, the CN ratio is high, and a good fermentation state is maintained, the decayed chips 19 can be obtained in a short period of time compared to the conventional method. In addition, since the trees pruned by road planting and the like can be quickly processed and used for the soil layer 14, effective use of the pruned trees and reduction of disposal costs can be achieved.

  And since rice bran is used as a moisture adjusting material, the water retention of the customer soil layer 14 becomes good, and the humidity of the customer soil layer 14 is kept good. Unlike the case where sawdust is used as the moisture adjusting material, no phenolic component is generated at the time of decomposition. Therefore, germination damage and growth damage are caused to plants planted in the soil layer 14 including the obtained decayed chips 19. It does not occur and the plant grows well. Therefore, plant management becomes easy.

  In the present embodiment, a plurality of rainwater storage tanks 1, 1,... Are connected to each other, and rainwater that has passed through the soil layer 14 is stored in the rainwater storage tanks 1, 1,. Even if the amount of stored water exceeds the total amount stored in the rainwater storage tanks 1, 1,... Therefore, in the case of a so-called guerrilla rainstorm that is localized and falls within a short period of time, rainwater is once stored in the rainwater storage tanks 1, 1,... And drained or overflowed with a time difference. Therefore, it is possible to prevent damage caused by guerrilla rainstorms, such as preventing rainwater from flowing into rivers and flooding.

At predetermined locations such as between the soil layer 14 and the retaining member 16 in the customer soil layer 14 of the water source 10. It is desirable to have a storage place for

  The toilet 30, the bucket 53, the hose 52, and the toilet paper 54 are taken out from the toilet container bag 38. The toilet bowl 30 is arranged by fitting the fitting recesses 34, 34, 34, 34 of the mounting portion 37 of the toilet bowl 30 in accordance with the jigs 48, 48, and the toilet paper 54 is held by the holding member 24. The bucket 53 is assembled and placed on the toilet 30 side.

  Next, the blindfold member 20 is taken out from the containing bag 25 and assembled. The assembled blindfold member 20 is arranged so as to cover the toilet 30 and the user who uses the toilet 30.

  By connecting one end portion of the hose 52 to the hose connecting portion 18, the rainwater stored in the rainwater storage tanks 1, 1,... Of the water source 10 is drawn to the bucket 53 in the blindfold member 20. Since the water source 10 is installed on the ground, it is not necessary to pump up the stored rainwater, and the stored rainwater flows to the bucket 53 through the hose 52 by its own weight. For example, a pinch cock, a hose clip, or the like is provided at the other end of the hose 52 to interrupt the rainwater flow.

  After using the toilet 30, the user of the toilet 30 can wash his / her hands using rainwater stored in the bucket 53. The rainwater used for hand-washing is poured into the discharge passage 35 of the toilet 30 as the flushing water of the toilet 30. The rainwater falls into the sewer 60 connected to the manhole 50 through the drain 35 and the outlet 43. At this time, rainwater drops excrement adhered to the inside of the discharge path 35. Moreover, rainwater makes the excrement at the bottom of the sewer channel 60 fine and easy to flow with the force of falling from a high place, and also forms the flow of water by itself and allows the excrement to flow along the sewer channel 60. Therefore, even when a toilet is used in the event of a disaster and the amount of sewage is drastically reduced due to water outage, it is possible to prevent excrement from accumulating on the bottom of the sewage channel 60.

  In the present embodiment, the case where rainwater from the water source 10 is temporarily stored in the bucket 53 and used as hand-washing water and then used as the flushing water of the toilet 30 is described, but the present invention is not limited thereto. For example, rain water from the water source 10 may be used directly as the flush water of the toilet 30 by configuring the other end of the hose 52 so as to penetrate the toilet body 31 and communicate with the discharge path 35.
