Description

本発明は、防災エリアに設置し、洪水緩和機能を持つ雨水の浸透循環貯留槽に関する。詳しくは、一時的に貯水した雨水を地中に浸透させ、貯水した雨水の一部を循環浄化させて飲料に供する水が貯留されている、雨水の浸透循環貯留槽に係るものである。 The present invention relates to a rainwater infiltration circulation storage tank installed in a disaster prevention area and having a flood mitigation function. Specifically, the present invention relates to a rainwater infiltration circulation storage tank in which rainwater temporarily stored is infiltrated into the ground, and a portion of the stored rainwater is circulated and purified to be used for beverages.

ビルが林立しライフラインが機能化した大都市は、大規模な自然災害に対して最も危険な地域となる半面が隠されている。たとえば、都市における集中豪雨は、瞬時に下水道や用水路に排水されるため、排水路で急激な増水をもたらし、また大地震ではガス管や水道管が破断し、道路は車が溢れてその機能が失われ、住民や帰宅困難者が公園や広場に避難しても、広場ではライフラインが麻痺しており、飲料水にも事欠く事態が起こり得る。 Large cities with buildings and functional lifelines are hidden from being the most dangerous areas for large-scale natural disasters. For example, torrential rains in cities are drained instantly into sewers and irrigation canals, resulting in a sudden increase in drainage, and in major earthquakes, gas pipes and water pipes are broken, and roads overflow with cars and function. Even if residents and those who have difficulty getting home evacuate to parks or plazas, lifelines may be paralyzed in the plazas, and there may be a shortage of drinking water.

このような豪雨や地震災害に備え、公園などの防災エリアに雨水貯留槽を設け、洪水対策と非常時の水源確保の取組が行われているが、その多くの水源は、静止した嫌気的雰囲気で滞留されており、緊急時に飲料水として利用するに適さない。 In preparation for such heavy rains and earthquake disasters, rainwater storage tanks are set up in disaster prevention areas such as parks, and efforts are being made to prevent flooding and secure emergency water sources. It is not suitable for use as drinking water in an emergency.

そこで、例えば特許文献１には、芝生を第一の濾過槽とし、砂や石を敷き詰めて第二の濾過槽とし、第二の濾過槽内に地中散水管を配管し、合併浄化槽からの排水を濾過する排水濾過システムがある。 Therefore, for example, in Patent Document 1, lawn is used as a first filtration tank, sand and stones are laid down as a second filtration tank, an underground sprinkler pipe is piped in the second filtration tank, There is a wastewater filtration system that filters wastewater.

特開２００８−０８０３０５号JP 2008-080305 A

しかしながら、特許文献１に記載された排水濾過システムは、水を縦方向に循環させて浄化する濾過装置であるが、洪水対策がなされていない。
都市部は、ほぼ全域がアスファルトやコンクリートで覆われていて、一時的に降る大量の雨は、瞬時に下水道や用水路に集中し、しばしば災害をもたらしているが、前記技術ではその対策がされていない。 However, the drainage filtration system described in Patent Document 1 is a filtration device that circulates and purifies water in the vertical direction, but does not take measures against flooding.
In urban areas, almost all areas are covered with asphalt and concrete, and a large amount of rain that falls temporarily concentrates on sewers and irrigation canals instantly, often resulting in disasters. Absent.

本発明は、以上の点を鑑み創案されたものであり、緊急避難に供される防災エリアにおいて、大量の雨を一時的に貯水する事によって洪水を緩和し、貯水した水を時間差を設けて地下に染み込ませ、同時に貯水した雨水の一部を利用し、湧水のような飲料水が貯留されている防災エリアの提供を課題とする。 The present invention was devised in view of the above points, and in a disaster prevention area used for emergency evacuation, flooding is eased by temporarily storing a large amount of rain, and the stored water is provided with a time difference. The problem is to provide a disaster prevention area where drinking water such as spring water is stored by using a part of rainwater soaked in the basement and stored at the same time.

たとえば、沖縄県宮古島は、平坦な台地状の***サンゴ礁の島であって、面積が１５８平方キロメートルもある大きな島でありながら、また巨大台風が襲う豪雨地帯でありながら河川がない、また、鹿児島県東部の平坦なシラス台地上にも河川がない、この両方の台地に共通する特徴は、雨は素早く地中に染み込み、特定の場所から清らかな湧水として噴出している。
本発明は、これら台地の地形、地質を参考にして創案されたものであり、都市公園の地下を利用する事によって、短時間豪雨による急激な洪水を緩和し、前記台地が持つ浄化システムを応用する事によって清涼な飲料水が常時貯留されている防災エリアの提供を課題とする。 For example, Miyakojima, Okinawa Prefecture is a flat plateau-shaped uplifted coral reef island, a large island with an area of 158 square kilometers, and a heavy rainstorm area hit by a huge typhoon, but no rivers. Kagoshima Prefecture There are no rivers on the flat Shirasu plateau in the eastern area. The common feature of both plateaus is that rain quickly soaks into the ground and erupts from certain locations as clean spring water.
The present invention was created with reference to the topography and geology of these plateaus, and by using the underground of a city park, the rapid flood due to heavy rain for a short time is alleviated and the purification system possessed by the plateau is applied. The challenge is to provide a disaster prevention area where cool drinking water is always stored.

上記の目的を達成するために、地中に埋設されている雨水の浸透循環貯留槽であって、前記浸透循環貯留槽は、浸透槽と循環貯留槽によって構成されており、前記浸透槽は、地下の地面に接して所定面積を有する浸透槽床面があり、前記浸透槽床面を取り囲むように周縁部の地層面に接して所定高さの浸透槽側面があり、前記浸透槽床面及び前記浸透槽側面が透水性部材で形成されており、前記循環貯留槽は、前記浸透槽床面の所定面積以内の面積を有する循環貯留槽床材が、前記浸透槽床面から離れた上方に位置して形成され、前記浸透槽側面の所定高さ以内の高さを有する循環貯留槽側壁が、前記循環貯留槽床材の周縁部上方を取り囲むように接続され、前記循環貯留槽側壁は前記浸透槽側面から離れた内側に位置して形成され、前記循環貯留槽床材及び前記循環貯留槽側壁が不透水性部材で形成されており、前記循環貯留槽床材の上面近郊にある吸入口から上方の排出口に向って、水を配水する揚水手段が設けられており、少なくとも前記浸透槽と前記循環貯留槽の内部に、連続気孔を有する多孔質部材が少なくとも充填されている雨水の浸透循環貯留槽を備える。 In order to achieve the above object, it is a rainwater infiltration circulation storage tank buried in the ground, wherein the infiltration circulation storage tank is constituted by an infiltration tank and a circulation storage tank, There is an infiltration tank floor surface having a predetermined area in contact with the underground ground, and there is an infiltration tank side surface having a predetermined height in contact with the formation surface of a peripheral portion so as to surround the infiltration tank floor surface, A side surface of the permeation tank is formed of a water permeable member, and the circulation storage tank has a circulation storage tank floor material having an area within a predetermined area of the permeation tank floor surface above the permeation tank floor surface. The circulation storage tank side wall formed at a position and having a height within a predetermined height on the side surface of the permeation tank is connected so as to surround the periphery of the circulation storage tank floor material, and the circulation storage tank side wall is Formed on the inner side away from the side surface of the infiltration tank, The storage tank floor material and the side wall of the circulation storage tank are formed of an impermeable member, and a pumping means for distributing water from the suction port near the upper surface of the circulation storage tank floor material toward the upper discharge port. A rainwater permeation circulation storage tank is provided which is provided at least inside the permeation tank and the circulation storage tank and is filled with a porous member having continuous pores.

また、本発明は、豪雨災害軽減の課題に対し、浸透槽の内部に貯水された水を素早く地中に浸透させるために、浸透槽床面及び浸透槽側面の少なくとも一部または全部が、透水性部材で形成される事もあり、或いは地下の地面及び地層面をそのまま浸透槽床面及び浸透槽側面として利用する事もあり、両者の透水性能に大きな開きはない。
なお、本発明では、地上の土壌面を地表と表示し、地表下の土壌内部を地中と表示し、周囲の地表より一段下方に下がった部分を地下と表示し、地下にあって略水平方向に広がる面を地下の地面と表示し、地下にあって略鉛直方向に広がる面を地層面と表示し、定義する。 Further, the present invention is directed to the problem of mitigating heavy rain disasters. In order to quickly infiltrate the water stored in the infiltration tank into the ground, at least part or all of the infiltration tank floor surface and the infiltration tank side surface are permeable to water. In some cases, it may be formed of a conductive member, or the underground ground and the formation surface may be used as they are as the permeation tank floor surface and the permeation tank side surface.
In the present invention, the soil surface on the ground is displayed as the ground surface, the inside of the soil below the ground surface is displayed as the underground, the portion that is one step below the surrounding ground surface is displayed as the underground, The surface that extends in the direction is displayed as the underground ground, and the surface that extends underground and extends in the substantially vertical direction is displayed as the formation surface.

また、本発明の循環貯留槽は、外側にある浸透槽よりも小さく、浸透槽の内部にあって浸透槽から独立して設置されている。その理由は、貯水した水を素早く地中に浸透させるために、浸透槽の表面積を最大限に保つためである。 Moreover, the circulation storage tank of the present invention is smaller than the permeation tank on the outside, and is installed inside the permeation tank and independently of the permeation tank. The reason is to keep the surface area of the infiltration tank to the maximum so that the stored water can quickly penetrate into the ground.

また、本発明の浸透槽と循環貯留槽の内部に、連続気孔を有する多孔質部材が充填されている事は、空間を埋める事によって上方の蓋が省略でき、空間が無いのに大量の雨を一時的に貯水する事ができ、貯水した水を時間差を設けて地中に染み込ませるためである。
なぜならば、連続気孔を有する多孔質部材は、粒子内部にある細孔が粒子外にまで繋がっているため細孔内に通水され、細孔内部までが貯水可能な空間となり、粒子間の空隙と合わせて大容量の貯水が可能な容積が確保され、同時に、水が排出される順序として、まず最初に粒子間の空隙に貯水された水が地中に排出され、粒子内部の細孔中に貯水された水がそれよりも遅れて浸透排出されるために時間差が生じ、スムースに地中に浸透させる事ができる。 In addition, the porous member having continuous pores is filled in the permeation tank and the circulation storage tank of the present invention, so that the upper lid can be omitted by filling the space, and there is a large amount of rain even though there is no space. This is because water can be temporarily stored, and the stored water is soaked in the ground with a time difference.
This is because a porous member having continuous pores has pores inside the particles connected to the outside of the particles, so that water can be passed through the pores and the inside of the pores can be stored in water, and the voids between the particles In addition, a volume capable of storing a large volume of water is secured, and at the same time, as the order in which water is discharged, the water first stored in the voids between the particles is discharged into the ground, and the pores inside the particles are discharged. Since the water stored in the water is drained and discharged later than that, a time difference occurs, and the water can smoothly penetrate into the ground.

また、本発明の循環貯留槽が不透水性部材で形成されている事は、貯水した雨水の一部を飲料水として利用するためであり、飲料水として適する水にまで浄化させるため、揚水手段を用いて貯留されている雨水を上方に配水し、上方の排出口から溢れ出た水が連続気孔を有する多孔質部材の表面及び細孔内部を通過しながら落下し、多孔質部材に住みついた微生物によって不純物が消費され、不純物が消費除去される事によって水が浄化され、飲料水として利用できる水として貯留される。
なお、本発明では、浸透循環貯留槽内を移動する水を配水と表現し、外部へ排出する水を排水または浸透と表現する。また、配水貯水槽や浸透槽内にあって状況の変化によって水位が変動する水を貯水と表現し、循環する事によってほぼ一定の水位が確保されている水を貯留と表現し、定義する。 In addition, the fact that the circulating storage tank of the present invention is formed of an impermeable member is for using a part of the stored rainwater as drinking water, and for purifying it into water suitable as drinking water, The rainwater stored in the water was distributed upward, and the water overflowing from the upper discharge port dropped while passing through the surface of the porous member having continuous pores and the inside of the pore, and settled on the porous member. Impurities are consumed by microorganisms, and the impurities are consumed and removed, so that water is purified and stored as water that can be used as drinking water.
In addition, in this invention, the water which moves the inside of an osmosis | circulation circulation storage tank is expressed as water distribution, and the water discharged | emitted outside is expressed as drainage or infiltration. In addition, water in the water distribution tank or infiltration tank whose water level fluctuates due to changes in the situation is expressed as storage water, and water in which an almost constant water level is secured by circulation is expressed and defined as storage.

以下、本発明の基となる雨水の浸透循環貯留槽１の実施の形態について図面を参照しながら説明し、本発明の理解に供する。 Hereinafter, embodiments of the rainwater infiltration circulation storage tank 1 which is the basis of the present invention will be described with reference to the drawings for understanding of the present invention.

本発明の基となる雨水の浸透循環貯留槽１は、その概要を図１の透視図で表し、図２は第一の実施態様を表す概略図である。また、図２の浸透循環貯留槽１が集中豪雨によって満水状態となった態様を図３で表し、図３の浸透循環貯留槽１において暫らく降雨がなく、浸透槽２の水が地下に浸透し、循環貯留槽３のみの水が循環し、浸透槽２が再び貯水可能な状態となっている態様を図４で表した。 The rainwater infiltration circulation storage tank 1 as the basis of the present invention is schematically shown in a perspective view of FIG. 1, and FIG. 2 is a schematic view showing a first embodiment. Further, FIG. 3 shows a state in which the osmotic circulation storage tank 1 of FIG. 2 is filled with heavy rain, and in the osmosis circulation storage tank 1 of FIG. Then, the mode in which only the water in the circulation storage tank 3 circulates and the permeation tank 2 can be stored again is shown in FIG.

図１は、本発明の基となる雨水の浸透循環貯留槽１であって、雨水の浸透循環貯留槽１を構成する角型の浸透槽２と、浸透槽２の内部にある角型の循環貯留槽３と、揚水手段４の概要を表した透視図であって、簡略化するため多孔質部材７の表示は省略した。 FIG. 1 shows a rainwater infiltration circulation storage tank 1 as a basis of the present invention, which is a rectangular infiltration tank 2 constituting the rainwater infiltration circulation storage tank 1 and a square circulation in the inside of the infiltration tank 2. It is the perspective view showing the outline | summary of the storage tank 3 and the pumping means 4, Comprising: The display of the porous member 7 was abbreviate | omitted for simplification.

図１の浸透槽２は、地中に凹状の穴を掘って地下を形成し、地下の地面１７に合成樹脂繊維のネットとシラス（いずれも透水性部材６ａの一例である）を平面状に積層して所定面積の浸透槽床面２ａを形成し、その浸透槽床面２ａの上方を取囲む所定高さの地層面１８を、合成樹脂繊維のネットとシラスで積層し、浸透槽側面２ｂを形成した。 The infiltration tank 2 in FIG. 1 digs a concave hole in the ground to form an underground, and a net of synthetic resin fibers and a shirasu (both are examples of the water permeable member 6a) on the underground ground 17 in a planar shape. The permeation tank floor surface 2a having a predetermined area is laminated, and the formation surface 18 having a predetermined height surrounding the permeation tank floor surface 2a is laminated with a synthetic resin fiber net and a shirasu, and the permeation tank side surface 2b. Formed.

しかし、浸透槽床面２ａ及び浸透槽側面２ｂは、いずれも透水性部材６ａを使用することなく、地下の地面１７または地層面１８をそのまま利用して浸透槽床面２ａまたは浸透槽側面２ｂとして利用する事もできる。 However, the permeation tank floor surface 2a and the permeation tank side surface 2b are both used as the permeation tank floor surface 2a or the permeation tank side surface 2b using the underground ground 17 or the formation surface 18 as they are without using the water-permeable member 6a. It can also be used.

この場合、浸透槽床面２ａの所定面積と浸透槽側面２ｂの所定高さとは、周囲から集めた雨水を貯水するために一定の容積が必要なためであり、地形や周囲の環境によって大きさは異なるが、浸透槽側面２ｂの上部は略水平である事が好ましい。 In this case, the predetermined area of the permeation tank floor surface 2a and the predetermined height of the permeation tank side surface 2b are because a certain volume is required to store rainwater collected from the surroundings, and the size depends on the topography and the surrounding environment. However, it is preferable that the upper part of the permeation tank side surface 2b is substantially horizontal.

また本実施例では、透水性部材６ａの一例として合成樹脂繊維のネットとシラスを挙げたが、これらに限定されるものではなく、定型或いは不定形を問わず透水性を有する部材であれば良い、しかし、価格或いは工事の簡易性なども考慮し、或いは地震による地殻変動に対して順応できる軟質素材が好ましい。 In the present embodiment, the net and shirasu of synthetic resin fibers are given as an example of the water permeable member 6a. However, the present invention is not limited to these, and any member having water permeability may be used regardless of the regular shape or the irregular shape. However, it is preferable to use a soft material that can be adapted to the crustal deformation caused by an earthquake in consideration of the price or the simplicity of construction.

また、図１の循環貯留槽３は、浸透槽床面２ａ及び浸透槽側面２ｂから離れた浸透槽の内側にあって、循環貯留槽床材３ａと循環貯留槽側壁３ｂが一体成型されているが、その製法に関しては図２欄で記述する。 Moreover, the circulation storage tank 3 of FIG. 1 is inside the penetration tank away from the penetration tank floor surface 2a and the penetration tank side surface 2b, and the circulation storage tank floor material 3a and the circulation storage tank side wall 3b are integrally formed. However, the manufacturing method is described in the column of FIG.

また図１において、循環貯留槽３が浸透槽２の内部に収まるためには、循環貯留槽床材３ａの面積が浸透槽床面２ａの所定面積よりも縦横共に小さく、循環貯留槽側壁３ｂの高さが浸透槽側面２ｂの所定高さよりも低い位置にある事により、循環貯留槽３は浸透槽２の内部に収容されている。 Further, in FIG. 1, in order for the circulating storage tank 3 to be accommodated in the infiltration tank 2, the area of the circulating storage tank flooring 3a is smaller than the predetermined area of the infiltration tank floor surface 2a both vertically and horizontally, The circulating storage tank 3 is accommodated inside the infiltration tank 2 because the height is lower than the predetermined height of the infiltration tank side surface 2 b.

また、循環貯留槽３に貯留されている水が飲料に供される水８ａとなるには、多孔質部材７間を流れ下りながら浄化される事が必要であり、水を鉛直方向に循環させるために、上方へ水を配水する揚水手段４が必要になる。 Moreover, in order for the water stored in the circulation storage tank 3 to become the water 8a to be used for beverages, it is necessary to purify while flowing down between the porous members 7, and to circulate the water in the vertical direction. The pumping means 4 for distributing water upward is required.

この揚水手段４は、多孔質部材７間を流れ落ちてきた水が最後に到達する循環貯留槽床材３ａの上面近郊に吸入口４ａを設け、浸透槽２の上方に排出口４ｂを設け、揚水手段４によって水を吸入口４ａから排出口４ｂへ配水し、多孔質部材間を自然落下させる事によって鉛直方向に循環し、多孔質部材７に棲みついた微生物によって浄化され、或いは濾過される事によって、湧水のような飲料に供する水８ａが貯留される。 This pumping means 4 is provided with a suction port 4a in the vicinity of the upper surface of the circulating storage tank floor 3a where water that has flowed down between the porous members 7 finally arrives, and is provided with a discharge port 4b above the permeation tank 2. Water is distributed from the suction port 4a to the discharge port 4b by the means 4, circulated in the vertical direction by naturally dropping between the porous members, and purified or filtered by microorganisms clinging to the porous member 7. Thus, water 8a to be used for a beverage such as spring water is stored.

図２は、本発明の代表的な実施例として、四角形の逆台形をした雨水の浸透循環貯留槽１の断面を示した側面図である。 FIG. 2 is a side view showing a cross section of a rainwater permeation and circulation storage tank 1 having a square inverted trapezoidal shape as a typical embodiment of the present invention.

図２の浸透槽２は、上方が広く、掘り下げるに従って狭くなる逆台形状の地層面１８と略平坦な地下の地面１７を持ち、この地下の地面１７及び地層面１８にシラス（透水性部材６ａの一例である）を敷詰め、その上から合成樹脂繊維のネット（透水性部材６ａの一例である）を敷き、略平坦な浸透槽床面２ａと、上方が外側に傾斜した浸透槽側面２ｂが出来上がった。 The infiltration tank 2 in FIG. 2 has an inverted trapezoidal formation surface 18 and a substantially flat underground ground 17 that are wide at the top and narrow as they are dug down, and a shirasu (water-permeable member 6a) is formed on the underground ground 17 and the formation surface 18. And a synthetic resin fiber net (which is an example of the water permeable member 6a), a substantially flat permeation tank floor 2a, and a permeation tank side 2b whose upper side is inclined outward. Was completed.

この場合に、浸透槽床面２ａまたは浸透槽側面２ｂの少なくとも一部が、透水性部材６ａを使用する事無く、地下にある地面１７または周縁部の地層面１８をそのまま利用し、浸透槽床面２ａまたは浸透槽側面２ｂとして使用する事もできる。 In this case, at least a part of the permeation tank floor surface 2a or the permeation tank side surface 2b uses the underground ground 17 or the stratum surface 18 at the peripheral portion as it is without using the water permeable member 6a, and the permeation tank floor. It can also be used as the surface 2a or the permeation tank side surface 2b.

この、浸透槽側面２ｂが、上方が外側に傾斜した逆台型の形状をしているのは、浸透槽２に貯水された水８ｂが、浸透槽側面２ｂから地下へ浸透するのを助け、外側から浸透槽２内に逆流するのを防止するためである。
なぜならば、水は重力に従って下方へ移動するため、外側の水が重力に逆らって浸透槽２内に流入する可能性は極めて少ない。 The infiltration tank side surface 2b has an inverted trapezoidal shape with the upper side inclined outward, which helps the water 8b stored in the infiltration tank 2 to penetrate underground from the infiltration tank side surface 2b. This is to prevent backflow into the infiltration tank 2 from the outside.
This is because water moves downward according to gravity, and therefore, there is very little possibility that water on the outside flows into the permeation tank 2 against gravity.

また、浸透槽側面２ｂ及び浸透槽床面２ａを形成する透水性部材６ａは、透水性コンクリートなど定型の部材もあるが、透水性の軟質プラスチック部材、或いは透水性を有する土壌などの不定形部材、或いはこれらが積層されて形成される事が好ましい。
なぜならば、これらの透水性部材６ａは、地面の凹凸に順応して浸透槽側面２ｂ及び浸透槽床面２ａが形成され、浸透槽２内部に充填された多孔質部材７（例えば軽石やスラグ）によって内圧と外圧が均衡した地下構造が成立し、大地震による地殻変動に対しても柔軟に地中と連動できる事が大きな要素である。 Further, the water permeable member 6a forming the osmotic tank side surface 2b and the osmotic tank floor surface 2a may be a fixed member such as permeable concrete, but a permeable soft plastic member or an indeterminate member such as water permeable soil. Alternatively, it is preferable that these are laminated.
This is because these permeable members 6a are formed with a permeation tank side surface 2b and a permeation tank floor surface 2a in accordance with the unevenness of the ground, and are filled in the permeation tank 2 (for example, pumice or slag). As a result, an underground structure with a balance between internal and external pressure is established, and it is a major factor that it can be flexibly linked to the ground even in the case of crustal deformation caused by a large earthquake.

次に、近郊の建物や道路の雨水を集水した流入口９ａを、浸透槽側面２ｂの上部に接続し、浸透槽２が完成した。 Next, the inflow tank 2 was completed by connecting the inflow port 9a, which collected rainwater from nearby buildings and roads, to the upper part of the infiltration tank side surface 2b.

続いて、地中にコンクリート杭（固定手段１２の一例である）を打ち込み、杭の上端を浸透槽床面２ａの上方略１ｍ地点に留め、浸透槽床面２ａから杭上端の高さまで軽石（多孔質部材７の一例である）を敷詰めた。 Subsequently, a concrete pile (which is an example of the fixing means 12) is driven into the ground, and the upper end of the pile is fastened to a point approximately 1 m above the infiltration tank floor 2a, and the pumice (from the infiltration tank floor 2a to the height of the upper end of the pile is This is an example of the porous member 7).

次に、敷詰めた軽石の上にプラスチックシートとコンクリート（不透水性部材６ｂの一例である）でもって循環貯留槽床材３ａを成型し、その上方を囲むように循環貯留槽側壁３ｂを成型して床材と一体化させ、浸透槽２の内部に、独立した（多孔質部材を通じては繋がっているが）箱型の循環貯留槽３が完成した。 Next, the circulating storage tank flooring 3a is molded with plastic sheet and concrete (an example of the water-impermeable member 6b) on the pumice laid, and the circulating storage tank side wall 3b is molded so as to surround the top. Then, it was integrated with the flooring, and the box-shaped circulation storage tank 3 was completed inside the infiltration tank 2 (although connected through the porous member).

また、本発明の循環貯留槽３が浸透槽２の内部に独立して設置されている理由は、集中豪雨などによって貯水した大量の水８ｂを素早く地中に浸透させるために、浸透槽２の表面積を最大限に保つためであり、今一つは、地震に対する防御対策として、循環貯留槽３が独立して固定されている事が好ましい。 The reason why the circulating storage tank 3 of the present invention is independently installed in the infiltration tank 2 is that the large amount of water 8b stored by concentrated heavy rain or the like is quickly infiltrated into the ground. This is in order to keep the surface area to the maximum, and the other is that the circulation storage tank 3 is preferably fixed independently as a countermeasure against earthquakes.

また、循環貯留槽床材３ａは、略３％の傾斜を設けて制作する事によって、揚水手段４の吸入口４ａを設置するに適した最下点が出現した。 In addition, the circulation storage tank flooring 3a was produced with an inclination of about 3%, and the lowest point suitable for installing the suction port 4a of the pumping means 4 appeared.

図２に示した揚水手段４は、循環貯留槽３に貯留されている水を循環し浄化させるために、循環貯留槽床材３ａの上面近郊にある吸入口４ａからいったん地上にある配水用貯水槽５に配水し、貯水した配水用貯水槽５を経由し、浸透槽２の上層部内に埋設した排出口４ｂから水を溢れさせる役目を担っている。また、図２では排出口４ｂが１本の線状に描かれているが、この排出口４ｂは、横方向の縦横に広がり、面状に配列されている。 In order to circulate and purify the water stored in the circulation storage tank 3, the pumping means 4 shown in FIG. 2 temporarily stores the water for distribution on the ground from the inlet 4a near the upper surface of the circulation storage tank flooring 3a. It distributes water to the tank 5, and plays a role of overflowing water from the discharge port 4 b embedded in the upper part of the permeation tank 2 through the stored water storage tank 5. In FIG. 2, the discharge ports 4 b are drawn in a single line, but the discharge ports 4 b extend in the horizontal and vertical directions and are arranged in a planar shape.

この揚水手段４は、動力として平常時は電動モーターを利用し、（或いは自然エネルギーを利用して水を汲み上げ）配水用貯水槽５内の水面が下限位置に達した時にモーター（揚水手段４の一例である）が稼働し、上限位置で停止し、常時、配水用貯水槽５の水位が一定範囲内にある様に調節されている。
と同時に、災害時に備え、揚水手段４は手動ポンプと併用した複数の揚水システムが好ましい。 This pumping means 4 normally uses an electric motor as power (or pumps up water using natural energy) when the water level in the water storage reservoir 5 reaches the lower limit position. Is an example), stops at the upper limit position, and is constantly adjusted so that the water level in the water distribution reservoir 5 is within a certain range.
At the same time, in preparation for a disaster, the pumping means 4 is preferably a plurality of pumping systems combined with a manual pump.

また、この配水用貯水槽５は、地上に設置する事によって高低差が利用でき、上方に通気口を設ける事によって大気圧が利用でき、配水用貯水槽５の水面表面積を排出口表面積の和よりも大きくし、複数の排出口４ｂから均等に水を溢れ出させるため、複数の排出口４ｂの高さ位置を水平にした。 In addition, the water storage tank 5 can be used on the ground to make a difference in elevation, and by providing a vent on the upper side, atmospheric pressure can be used, and the water surface area of the water storage tank 5 is the sum of the surface area of the discharge ports. In order to allow water to overflow evenly from the plurality of outlets 4b, the height positions of the plurality of outlets 4b were made horizontal.

また、この配水用貯水槽５は、蛇口を併設する事によって飲料や散水に利用でき、或いは濾過材１１を充填して浄水機能を持たせ、或いは専用の浄水器と併設する等、種々の方法と複合した水の有効利用が好ましい。 In addition, the water storage tank 5 can be used for beverages and watering by providing a faucet, or can be used for various methods such as filling the filter material 11 to have a water purification function, or providing a dedicated water purifier. The effective use of water combined with is preferable.

この、排出口４ｂから溢れ出た水は、連続気孔を有する多孔質部材７の表面或いは細孔内部を通過しながら下方へ移動し、好気性雰囲気中を移動する事によって小川のせせらぎの如く浄化され、常時循環する事によって飲料に供される水８ａとなって貯留される。 The water overflowing from the discharge port 4b moves downward while passing through the surface of the porous member 7 having continuous pores or inside the pores, and is purified like a stream of a stream by moving in an aerobic atmosphere. The water 8a supplied to the beverage is stored by being constantly circulated.

また、本実施例の図２では、各部材の配置位置を明確に表示するため多孔質部材７の表示を右端の一部に留めたが、浸透槽２及び循環貯留槽３の内部に軽石（多孔質部材の一例である）を敷詰めた。 Further, in FIG. 2 of the present embodiment, the porous member 7 is displayed at a part of the right end in order to clearly display the arrangement position of each member, but the pumice ( Which is an example of a porous member).

また、本実施例では連続気孔を有する多孔質部材７として軽石を使用したが、その他にも連続気孔を有する多孔質部材７としては、本実施例で用いた天然鉱物（軽石やボラ土）、或いは化石（例えば、サンゴ粒）、或いは人工の多孔質部材（例えば、リサイクルされた連続気孔の発砲ガラスやＣ型シリカゲル）、或いは製造に供された廃材（例えば、スラグや石炭ガラ）などがある。
それらは、火山ガスが噴出した孔（例えば鹿児島産軽石の細孔は、１μ〜３ｍｍまで）であり、サンゴ虫が出入りした孔であって、多くの多孔質部材中にあっても大きな連続気孔を持つ部類であり、その細孔径が大きいが故に気孔率が大きく、半面で保水力が弱く、保水力が弱いが故に上方で放出された水が重力によって細孔内を容易に通過する事ができ、粒子の表面及び内部で好気的雰囲気にさらされ、一般的に無害といわれる好気性微生物によって不純物が消費され、濾過ではなく消費されるが故に浄化作用が持続される。 Moreover, in this example, pumice was used as the porous member 7 having continuous pores. However, as the porous member 7 having continuous pores, other natural minerals (pumice and borax) used in this example, Or there are fossils (for example, coral grains), artificial porous members (for example, recycled glass with open pores or C-type silica gel), or waste materials (for example, slag or coal galley) provided for production. .
These are pores from which volcanic gas has been ejected (for example, the pores of pumice from Kagoshima are from 1 μm to 3 mm), and coral insects have entered and exited the pores, which are large continuous pores even in many porous members. Since the pore diameter is large, the porosity is large, the water retention power is weak on one side, and the water released above can easily pass through the pores by gravity because the water retention power is weak. The impurities are consumed by aerobic microorganisms that are exposed to the aerobic atmosphere on the surface and inside of the particles and are generally said to be harmless, and the purification action is sustained because they are consumed rather than filtered.

この場合、種々の環境や気象条件によっては、連続気孔を持つ多孔質部材であれば小さな細孔を持つ多孔質部材であっても良い。 In this case, depending on various environments and weather conditions, a porous member having small pores may be used as long as it is a porous member having continuous pores.

また、大きな細孔径を持つ多孔質部材といえども、加熱などにより絶乾状態となった多孔質部材内の細孔中には、水は表面張力によって容易に細孔内に入り込めないが、比較的多雨地帯にある日本の土壌中は高湿度状態にあり、浸透循環貯留槽１内にある多孔質部材は絶乾状態にはならない。 Moreover, even in a porous member having a large pore diameter, water cannot easily enter the pores due to surface tension in the pores in the porous member that has become completely dry by heating, The Japanese soil in a relatively heavy rain zone is in a high humidity state, and the porous member in the osmotic circulation storage tank 1 is not completely dry.

また、これらの多孔質部材７は、ｐＨがほぼ中性の安定した分子が多く、踏圧で容易に潰れない所定硬度（例えば、鹿児島産軽石のモース硬度は５〜６）を有し、粒径が一定範囲内の所定体積（例えば、粒径３ｍｍ〜１０ｍｍ程度）を有する多孔質部材７が好ましい。 Further, these porous members 7 have a predetermined hardness (for example, the Mohs hardness of pumice from Kagoshima is 5 to 6) which is not easily crushed by a treading pressure, since there are many stable molecules whose pH is almost neutral. Is preferably a porous member 7 having a predetermined volume within a certain range (for example, a particle size of about 3 mm to 10 mm).

しかし、浸透循環貯留槽１の上方が強固な部材で覆われている場合は、多孔質部材７の硬度は重要な要件とはならず、その他の条件があればよい。 However, when the upper part of the osmotic circulation storage tank 1 is covered with a strong member, the hardness of the porous member 7 is not an important requirement, and other conditions may be used.

また、これらの多孔質部材７が一定範囲内の所定体積を持つ事は、粒子と粒子の間に大きな空隙（例えば、粒径３ｍｍ〜１０ｍｍの軽石の粒子内部を含めた空隙率は７０％）が生じ、この大きな空隙によって、シンプルな構造でありながら、安価で大きな貯水力を持つ地下空間が誕生する。 In addition, these porous members 7 having a predetermined volume within a certain range means that large voids are formed between the particles (for example, the porosity including the inside of pumice particles having a particle diameter of 3 mm to 10 mm is 70%). As a result of this large gap, an underground space with a simple structure, yet low cost and large water storage capacity is born.

また、これらの多孔質部材７は、その成り立ちからして表面が無数の凹凸で覆われているものが多く、大きな体積と表面の凹凸などによって摩擦係数が大きな多孔質部材となっている。
この摩擦係数の大きな多孔質部材７は、地震による液状化現象が起きにくいと同時に、浸透槽内部にある循環貯留槽３を、大地震の衝撃から守る一因でもあり、好ましい。 In addition, these porous members 7 have many surfaces whose surfaces are covered with innumerable irregularities, and have a large friction coefficient due to their large volume and surface irregularities.
The porous member 7 having a large friction coefficient is preferable because it does not easily cause a liquefaction phenomenon due to an earthquake and at the same time protects the circulating storage tank 3 inside the permeation tank from the impact of a large earthquake.

また、水の浄化には多様な環境が存在する方が有利であるため、循環貯留槽３上部と浸透槽２が接する部位に、濾過材１１を充填した。
通常、濾過材１１としては、木炭、竹炭、ゼオライト等の細孔径の小さな多孔質部材、或いはシュロや麻などの繊維状部材、或いは浸透膜などの人工部材があるが、本実施例では木炭と粒径が小さい（例えば２ｍｍ〜４ｍｍ）軽石を混合し、循環貯留槽３上方に充填した。 Moreover, since it is more advantageous for water purification to have various environments, the filter medium 11 is filled in a portion where the upper part of the circulation storage tank 3 and the permeation tank 2 are in contact with each other.
Usually, the filter material 11 includes a porous member having a small pore diameter such as charcoal, bamboo charcoal, or zeolite, or a fibrous member such as palm or hemp, or an artificial member such as a permeable membrane. Pumice with a small particle size (for example, 2 mm to 4 mm) was mixed and filled above the circulating storage tank 3.

また、図２では飲料に供される水８ａと地中に浸透する水８ｂの２種類の水を表示したが、循環貯留槽３の多孔質部材７間の空隙に貯留され飲料に供される水８ａは、常時循環されて浄化されている水であり、浸透槽２下方の多孔質部材７間の空隙に貯水された水は、図３に示した満水状態から図４に至るまでの途中にある水位を表している。 In FIG. 2, two types of water, water 8a used for beverage and water 8b penetrating into the ground, are displayed. However, the water is stored in the space between the porous members 7 of the circulation storage tank 3 and used for beverage. The water 8a is constantly circulated and purified, and the water stored in the gap between the porous members 7 below the permeation tank 2 is halfway from the full state shown in FIG. 3 to FIG. Represents the water level.

また、図２に示す浸透循環貯水槽１は、浸透槽２の内部に達した流入口９ａの先端と循環貯留槽３との横方向の距離が大きいため、浸透槽内部の多孔質部材７間にシート状或いは板状の水の誘導部材１０を設置した。
この水の誘導部材１０は、不透水性部材６ｂからなり、水が流れる勾配（略２％とした）を有して設置される事が好ましい。 2 has a large lateral distance between the tip of the inlet 9a reaching the inside of the permeation tank 2 and the circulation storage tank 3, so that the porous member 7 between the permeation tanks is located between the porous members 7 inside the permeation tank. A sheet-shaped or plate-shaped water guiding member 10 was installed.
The water guiding member 10 is preferably made of an impermeable member 6b and installed with a gradient (approximately 2%) through which water flows.

また、この水の誘導部材１０は、揚水手段４の排出口４ｂから溢れ出た水が浸透槽２の多孔質部材７で拡散して減少するのを防ぎ、その水を効率よく循環貯留槽３に導く役目も担っている。 Further, the water guiding member 10 prevents the water overflowing from the discharge port 4b of the pumping means 4 from diffusing and decreasing in the porous member 7 of the permeation tank 2, and the water is efficiently circulated and stored in the circulation storage tank 3. It also has a role to lead to.

次に、図３について記述する。
図３は、図２に示した雨水の浸透循環貯留槽１において、集中豪雨或いは長期間の大雨によって大量の雨水が流れ込み、浸透槽２及び循環貯留槽３共に満水状態となった様子を表した。
この場合でも、循環貯留槽３内の水は、平常から循環貯留されている水８ａであり、浸透槽内に貯水されている水は、地中に浸透する水８ｂであり、雨が止み雨水の供給が無くなると徐々に地中に染み込んで水位が低下し、図２に記載した８ｂの水位を経過して最後に無くなる水である。 Next, FIG. 3 will be described.
FIG. 3 shows a state in which a large amount of rainwater has flowed into the rainwater infiltration circulation storage tank 1 shown in FIG. 2 due to concentrated heavy rain or long-term heavy rain, and both the infiltration tank 2 and the circulation storage tank 3 are full. .
Even in this case, the water in the circulation storage tank 3 is the water 8a that is normally circulated and stored, and the water that is stored in the infiltration tank is the water 8b that penetrates into the ground. When the water supply is lost, the water level gradually falls into the ground, the water level drops, and the water level finally disappears after the water level of 8b shown in FIG.

次に、図４について記述する。
図４は、図３で満水状態を示した浸透槽２において、時間の経過とともに多孔質部材７間の空隙に貯水された水８ｂが地中に浸透して消失し、続いて多孔質部材７内部の水が徐々に下方へ移動しながら地中に浸透し、やがて浸透槽２上方の多孔質部材７ｂ内部の水が失われて半乾燥状態となり、浸透槽２下方にある多孔質部材７ａがまだ水を含んだ状態となった時点を表した概略図である。 Next, FIG. 4 will be described.
FIG. 4 shows that the water 8b stored in the gap between the porous members 7 permeates into the ground and disappears with time in the infiltration tank 2 shown in FIG. The water in the interior gradually penetrates into the ground while moving downward, and eventually the water inside the porous member 7b above the infiltration tank 2 is lost and becomes semi-dry, so that the porous member 7a below the infiltration tank 2 It is the schematic showing the time of becoming a state still containing water.

この時、循環貯留槽では、揚水手段４によって循環貯留槽３内の吸入口４ａから浸透槽上部の排出口４ｂまで、たえず配水されており、排出口４ｂから溢れ出た水が多孔質部材の表面或いは内部を通過しながら流れ下って循環しており、浸透循環貯留槽１内が常時高湿度下に保たれ、循環貯留槽３内には飲料に供される水８ａが貯留されている。 At this time, in the circulation storage tank, water is constantly distributed from the suction port 4a in the circulation storage tank 3 to the discharge port 4b in the upper part of the permeation tank by the pumping means 4, and the water overflowing from the discharge port 4b is the porous member. The osmotic circulation storage tank 1 is constantly kept under high humidity while passing through the surface or inside, and the circulation storage tank 3 stores water 8a used for beverages.

図５は、大きな循環貯留槽３を有し、集中豪雨と長期間の少雨時期との両方が存在する地域に適した浸透循環貯留槽１であって、揚水手段４の排出口４ｂに向かうパイプが先端に行くにしたがって下方に傾斜し、排出口４ｂが循環貯留槽３内に達している浸透循環貯留槽１の一例を表した。 FIG. 5 shows an osmotic circulation storage tank 1 having a large circulation storage tank 3 and suitable for an area where both heavy rain and a long period of light rain exist, and a pipe directed to the outlet 4b of the pumping means 4 1 shows an example of the osmotic circulation storage tank 1 that is inclined downward as it goes to the tip, and the discharge port 4b reaches the circulation storage tank 3.

また、浸透槽２を埋設する地層が、粘土層などの不透水土壌で覆われている場合は、いくら浸透槽２を透水性部材６ａで製作しても水は地中に浸透しない。
従って、図６のＡ及びＢは、浸透槽側面２ｂ或いは浸透槽床面２ａの一部を通常の浸透槽床面２ａ位置より下方へ掘下げ、透水性を示す地層まで延長させる事が好ましい。 Moreover, when the ground layer which embeds the infiltration tank 2 is covered with impermeable soil such as a clay layer, water does not penetrate into the ground no matter how much the infiltration tank 2 is manufactured with the water permeable member 6a.
Therefore, in FIGS. 6A and 6B, it is preferable to dig a part of the permeation tank side surface 2b or the permeation tank floor surface 2a downward from the position of the normal permeation tank floor surface 2a and extend it to the formation layer showing water permeability.

前記の図６Ａは、浸透槽側面２ｂの一部を地中深くまで延長し、透水性土壌層である２ｘ地点で屈折して上方へ向かい、２ｙ地点で浸透槽床面２ａと接続しているが、これは、浸透槽側面２ｂの一部が地中深くに延長し、２ｘ地点で変形した浸透槽床面２ａと接続している、とも表現できる。
また、図６Ａの別の片方は、浸透槽側面２ｂの一部が浸透槽床面２ａの位置２ｘを過ぎて延長し、湾曲して２ｙ地点で浸透槽床面２ａに接続しているが、これも、浸透槽側面２ｂと変形した浸透槽床面２ａが２ｘ地点で接続している、とも表現できる。 In FIG. 6A, a part of the side surface 2b of the permeation tank is extended deep into the ground, refracted at the 2x point that is the permeable soil layer, and directed upward, and connected to the permeation tank floor surface 2a at the 2y point. However, this can also be expressed as a part of the permeation tank side surface 2b extending deep into the ground and connected to the permeation tank floor surface 2a deformed at the 2x point.
6A, a part of the permeation tank side surface 2b extends past the position 2x of the permeation tank floor surface 2a, is curved, and is connected to the permeation tank floor surface 2a at the 2y point. This can also be expressed as that the permeation tank side surface 2b and the deformed permeation tank floor surface 2a are connected at a point 2x.

図６Ｂは、浸透槽床面２ａの一部を透水性土壌層まで掘下げ、変形した浸透槽床面２ａと浸透槽側面２ｂが２ｘ地点で接続されている浸透循環貯留槽１である。 FIG. 6B shows the osmotic circulation storage tank 1 in which a part of the osmotic tank floor surface 2a is dug down to the permeable soil layer, and the deformed osmotic tank floor surface 2a and the osmotic tank side surface 2b are connected at a point 2x.

図７に示す、大きな浸透槽２の内部に独立した複数の循環貯留槽３が組合わさった浸透循環貯留槽１の断面を表す簡略図は、大規模な浸透循環貯留槽１を設置する場合に有効な形状である。
なぜならば、豪雨災害に対しては、浸透槽が大容量であるほど好ましい必修条件であり、地震災害に対しては、小規模或いは中規模の循環貯水槽が独立して設置されている事が安全であり、その両方の利便性を生かした浸透循環貯留槽１であって、被害を最小限に抑える有効な手段である。 The simplified diagram showing the cross section of the osmotic circulation storage tank 1 in which a plurality of independent circulation storage tanks 3 are combined inside the large osmosis tank 2 shown in FIG. It is an effective shape.
This is because, for heavy rain disasters, the larger the capacity of the infiltration tank, the more preferable it is, and for earthquake disasters, small or medium-scale circulation water storage tanks are installed independently. It is a permeation circulation storage tank 1 that is safe and takes advantage of both conveniences, and is an effective means for minimizing damage.

例えば、図７の浸透循環貯留槽１が、平均直径が１００ｍの略楕円形で深さが６ｍの浸透槽２であったとすれば、内部空間は略４７，１００立方メートルであって、内部に４個ある循環貯留槽の体積の合計が３０％であれば、浸透槽の内部空間は略３３，０００立方メートルであり、内部に充填している多孔質部材の空隙率が７０％と仮定すれば、計算上は略２３，０００立方メートルの浸透槽の空間体積が存在する。
しかし、既に吸水している部分なども考慮し、現実的に貯水可能な空間を半分程度と仮定しても、貯水可能な水は略１１，５００立方メートルである。
この量は、短時間降雨１００ｍｍの猛烈な豪雨があった時、その半分が貯水され、半分が排水されたと仮定すると、約２．３平方キロメートル範囲内に降った雨が貯水できた計算になる。 For example, if the osmotic circulation storage tank 1 of FIG. 7 is an osmosis tank 2 having an average diameter of 100 m and a depth of 6 m, the internal space is approximately 47,100 cubic meters and 4 If the total volume of the circulating storage tanks is 30%, assuming that the internal space of the permeation tank is approximately 33,000 cubic meters and the porosity of the porous member filled therein is 70%, In the calculation, there is a permeation tank space volume of approximately 23,000 cubic meters.
However, in consideration of a portion that has already absorbed water, the amount of water that can be stored is approximately 11,500 cubic meters, even assuming that the space that can be actually stored is about half.
This amount is calculated so that when there was a heavy downpour of 100 mm of short-term rainfall, half of the water was stored and half was drained, and rain that fell within about 2.3 square kilometers could be stored.

また、浸透槽２の内部に４個ある循環貯留槽３に貯留され飲料に供される水８ａは、容積略１４，１００立方メートル×空隙率７０％＝略１０，０００立方メートルの水が存在している計算であり、その半分量が即利用可能な水量と仮定すると、略５，０００立方メートルの飲料水が貯留されており、一人当たり１０リットルが必要だと仮定すれば５０万人分の水が確保されている計算になる。 In addition, the water 8a stored in the four circulation storage tanks 3 in the inside of the permeation tank 2 and used for beverages has a volume of approximately 14,100 cubic meters × 70% porosity = approximately 10,000 cubic meters. Assuming that half of that amount is water that can be used immediately, approximately 5,000 cubic meters of drinking water is stored. It is a secured calculation.

また、前記の浸透槽２内部に複数の循環貯留槽３が設けられた浸透循環貯留槽１において、複数の循環貯留槽３の揚水手段４が統合される場合もある。
例えば図7において、中央にある２個の循環貯留槽３から１個の配水用貯水槽５に配水し、１個の配水用貯水槽５から２個の循環貯留槽３上方にある排出口４ｂに配水する事により、簡略化したシステムが完成する。 Further, in the permeation circulation storage tank 1 in which a plurality of circulation storage tanks 3 are provided in the inside of the permeation tank 2, the pumping means 4 of the plurality of circulation storage tanks 3 may be integrated.
For example, in FIG. 7, water is distributed from two circulation storage tanks 3 in the center to one water storage tank 5, and the outlet 4 b is located above one circulation storage tank 3 from one water storage tank 5. Distributing water to completes a simplified system.

図８は、循環貯留槽床材３ａまたは循環貯留槽側壁３ｂの一部が浸透槽床面２ａまたは浸透槽側面２ｂの機能を代行している浸透循環貯水槽１であって、浸透槽側面２ｂの一部が浸透槽床面２ａの下方まで延長されて湾曲し、２ｙ地点で浸透槽床面２ａに接続されており、別の片方は浸透槽床面２ａと浸透槽側面２ｂの一部が循環貯留槽床材３ａと循環貯留槽側壁３ｂに合体しており、浸透槽の機能が制限されるが簡略化した浸透循環貯留槽１の一例を示した。 FIG. 8 shows an osmotic circulation water storage tank 1 in which a part of the circulation storage tank flooring 3a or the circulation storage tank side wall 3b performs the function of the osmosis tank floor surface 2a or the osmosis tank side surface 2b. Is partly extended to the lower side of the permeation tank floor surface 2a, is curved, and is connected to the permeation tank floor surface 2a at the 2y point, and the other one is a part of the permeation tank floor surface 2a and the permeation tank side surface 2b. An example of the permeation circulation storage tank 1 is shown which is combined with the circulation storage tank flooring 3a and the circulation storage tank side wall 3b and the function of the permeation tank is limited but simplified.

また、図８に記載した揚水手段４は、配水用貯水槽５から離れるに従って略２％の勾配を有して配水パイプが下降し、その配水パイプに上方に向う排出口４ｂを接続し、面状に広がる全ての排出口４ｂは水平方向の同位置になるよう調節した。 Further, the pumping means 4 shown in FIG. 8 has a slope of approximately 2% as it moves away from the water storage tank 5, and the water distribution pipe descends, and the discharge pipe 4b facing upward is connected to the water distribution pipe. All the discharge ports 4b spreading in a shape were adjusted to be in the same position in the horizontal direction.

また、面状に広がる全ての排出口４ｂから水が均等に噴出される事は、広範囲の多孔質部材７が有効に利用され、広範囲の多孔質部材７が利用される事によって、浄化機能がより多く発揮される。 In addition, the fact that water is evenly ejected from all the discharge ports 4b spreading in a plane shape means that a wide range of porous members 7 are effectively used, and a wide range of porous members 7 are used, so that the purification function is improved. More.

また図９は、複数の循環貯留槽３が略水平方向に設置され、循環貯留槽３と循環貯留槽３の間に浸透槽床面２ａが接続され、循環貯留槽３と循環貯留槽３の間及び循環貯留槽３の上方を含む外周部を取囲むように浸透槽側面２ｂが形成されて、1個の浸透槽２内に複数の循環貯留槽３が形成され、一体化した浸透循環貯留槽が形成されている状態を表した簡略図であって、大規模災害に対する最も簡便かつ有効な防災手段である。 In FIG. 9, a plurality of circulation storage tanks 3 are installed in a substantially horizontal direction, and a permeation tank floor 2 a is connected between the circulation storage tank 3 and the circulation storage tank 3. The permeation tank side surface 2b is formed so as to surround the outer periphery including the space and the upper part of the circulation storage tank 3, and a plurality of circulation storage tanks 3 are formed in one permeation tank 2, and integrated permeation circulation storage It is the simple figure showing the state where the tank is formed, Comprising: It is the simplest and effective disaster prevention means with respect to a large-scale disaster.

図９で表した方法は、防災エリアに巨大な穴を掘り、集水口の要所ごとに循環貯留槽３を設置し、塩ビパイプ（揚水手段４の一例である）を設置しながら軽石（多孔質部材７の一例である）を充填し、循環貯留槽３間及び外周部にも軽石を充填し、実用的な、巨大な雨水の浸透循環貯留槽が完成した。 The method shown in FIG. 9 digs a huge hole in the disaster prevention area, installs a circulation storage tank 3 for each key point of the water collection port, and installs a PVC pipe (an example of the pumping means 4) while pumice (porous This is an example of the material member 7), and the pumice is filled between the circulation storage tanks 3 and the outer peripheral portion to complete a practical and enormous rainwater infiltration circulation storage tank.

図１０は、揚水手段４の排出口４ｂを表した拡大図であって、配水用貯水槽５からの高低差を利用して複数の排出口４ｂから均等に水を溢れさせるために、排出口を上方に向って設置し、全ての排出口４ｂを水平の同位置に保つ事が肝要である。 FIG. 10 is an enlarged view showing the discharge port 4b of the pumping means 4, and uses the height difference from the distribution water storage tank 5 to discharge water evenly from the plurality of discharge ports 4b. It is important to keep all the outlets 4b in the same horizontal position.

しかし、排出口４ｂを上方に向って設置すると色々な障害が発生する、即ち、植物の根は水を求めて伸長し、或いは上方から土砂や粒子が入り込み、目詰まりが発生する。
従って、排出口４ｂに覆いを設け、さらにその上から防草シートで覆った。 However, when the discharge port 4b is set upward, various obstacles occur, that is, the roots of the plant are stretched for water, or earth and sand and particles enter from above, resulting in clogging.
Therefore, a cover was provided on the discharge port 4b, and further covered with a weedproof sheet.

図１１に示した溜桝９は、流入口９ａが浸透槽２に至る手前で溜桝９に接続し、その溜桝９から、再び浸透槽に向う流入口９ｂと外部へ排水する排水管９ｃを追加し、それぞれを異なる位置と異なる方向に接続した。 The reservoir 9 shown in FIG. 11 is connected to the reservoir 9 just before the inlet 9a reaches the infiltration tank 2, and from the reservoir 9 to the inlet 9b toward the infiltration tank again and a drain pipe 9c for draining to the outside. And connected each in a different position and in a different direction.

この、異なる位置と異なる方向に接続する理由は、流入口９ａから流れてきた雨水が容積の大きな溜桝９に入って流速が弱まり、出口方向が変わる事によって渦と澱みが生じて土砂１６が沈殿し、再び浸透槽に向う流入口９ｂを低い位置に接続し、排水管９ｃを高い位置に接続する事によって、浸透槽が満杯になるまでは浸透槽２に供給し、満杯となった時点で排水管９ｃに導き、浸透槽２のオーバーフローを回避させる。 The reason for connecting to this different position and different direction is that rainwater flowing from the inflow port 9a enters the large-capacity basin 9 and the flow velocity is weakened. When the inlet 9b that has settled and connected to the infiltration tank again is connected to the low position, and the drain pipe 9c is connected to the high position, it is supplied to the infiltration tank 2 until the infiltration tank is full. To the drain pipe 9c to avoid overflow of the permeation tank 2.

また、溜桝９から再び浸透槽に向う流入口９ｂは、溜桝９に流入する流入口９ａよりも口径面積を広げ、勾配を緩くする事によってさらに流速が弱まり、土砂が沈殿し易くなる。
また集水する周辺の状況に応じて、この溜桝の複数個を接続する方法もあるが、別個の濾過専用の溜桝を設け、その溜桝との組合せが簡単で現実的である。 In addition, the inlet 9b from the reservoir 9 to the infiltration tank again has a larger caliber area than the inlet 9a flowing into the reservoir 9 and a gentler gradient, so that the flow velocity is further weakened and the sediment is more likely to settle.
There is also a method of connecting a plurality of reservoirs depending on the surrounding circumstances of collecting water, but a separate reservoir dedicated to filtration is provided, and the combination with the reservoir is simple and practical.

濾過専用の溜桝は、粒形の小さい多孔質部材とシラスを混合した濾過材を通過させ、定期的に濾過材の目詰まり部分を取除き、或いは交換する事によって、浸透槽の機能を長期間にわたって保つ働きがある。 The filtration tank dedicated to filtration extends the function of the permeation tank by allowing the filter material mixed with a porous member with a small particle shape and shirasu to pass through, and periodically removing or replacing the clogged portion of the filter material. There is work to keep over the period.

図１２は、様々な地形や環境に応じて変化する雨水の浸透循環貯留槽１について、多様な種類の一例を表した略図である。 FIG. 12 is a schematic diagram showing examples of various types of the rainwater permeation and storage tank 1 that changes according to various topography and environment.

図１２Ｃは、雨水の浸透循環貯留槽１が地中深くに設置されている様態を表し、図１２Ｄは、雨水の浸透循環貯留槽１が地表或いは地表近くに設置されている様態を表しているが、傾斜地に設置される場合など、この両方が混在した形も存在する。 FIG. 12C shows a state in which the rainwater infiltration circulation storage tank 1 is installed deep in the ground, and FIG. 12D shows an aspect in which the rainwater infiltration circulation storage tank 1 is installed near or on the ground surface. However, there are also forms where both are mixed, such as when installed on slopes.

図１２Ｅは、浸透循環貯留槽１の平面図で、浸透槽２が略円形や楕円形であり、内部の循環貯留槽３が四角の形状をしている様態を表し、図１２Ｆは、６角形の浸透槽２と略円形の循環貯留槽３を表している。 FIG. 12E is a plan view of the osmotic circulation storage tank 1, in which the osmosis tank 2 is substantially circular or elliptical, and the internal circulation storage tank 3 has a square shape. FIG. 12F is a hexagonal shape. The permeation tank 2 and the substantially circular circulation storage tank 3 are shown.

また、図１２Ｇは、上方が狭い浸透槽２と角型の循環貯留槽３が組合わさった側面を表し、図１２Ｈは、不定形の浸透槽２と不定形の循環貯留槽３の一部が合体した浸透循環貯留槽である。 12G shows a side surface in which the permeation tank 2 and the square-shaped circulation storage tank 3 are combined in a narrow upper part, and FIG. 12H shows a part of the irregular permeation tank 2 and the irregular circulation storage tank 3. Combined osmotic circulation storage tank.

また、本実施例の雨水の浸透循環貯留槽１内部に充填した多孔質部材７は、充分な硬度を有しているため、上方の地上は通常の公園や運動場としての用途に耐えられる。
従って、上方の地上部の少なくとも一部は、シラスや透水性を有する土壌で覆い、或いは舗装して通路として使用し、或いは芝生や花壇や樹木を植栽し、通常の公園や多目的広場としての機能を維持させる事ができる。 In addition, since the porous member 7 filled in the rainwater permeation circulation storage tank 1 of this embodiment has sufficient hardness, the upper ground can withstand use as a normal park or playground.
Therefore, at least a part of the upper ground part is covered with shirasu or water-permeable soil, or paved for use as a passage, or planted with lawns, flower beds, trees, etc. as a normal park or multipurpose plaza The function can be maintained.

その場合、本実施例の多孔質部材は、細孔径が大きいが故に保水力が弱い。
この保水力が弱いがために、浸透槽内に充填する素材として好ましい要件を備えているが、半面で、少雨地域にあっては地表が乾燥し、地表植物の生育に適さない場合が生じる。
従って、浸透槽の上部に、細孔径が小さく保水性に優れた多孔質部材（例えば、ゼオライト、珪藻土、木炭など）を、状況に応じて一部に利用する事もできる。 In that case, the porous member of this example has a small water retention because it has a large pore diameter.
Although this water retaining ability is weak, it has preferable requirements as a material to be filled in the permeation tank, but on the other hand, in a low rain area, the surface of the ground may be dry and not suitable for the growth of surface plants.
Therefore, a porous member (for example, zeolite, diatomaceous earth, charcoal, etc.) having a small pore diameter and excellent water retention can be partially used in the upper part of the permeation tank depending on the situation.

現在の大都市は、地表がアスファルトやコンクリートに覆われて透水性を失い、ビルが高層化してヒートアイランド現象が加速し、ここに外的条件が加われば上昇気流によって雷雲が発生し、急激な豪雨災害の危険性が潜んでいます。
また、地球温暖化の影響は、過去に例がなかったほどの集中豪雨や巨大台風の襲来が取りざたされており、その災害予防対策は緊急の課題です。
しかし、この豪雨災害を食い止めるには新たな大容量の排水設備が必要であり、それには膨大な費用と長い時間が必要でありますが、本発明は、至ってシンプルで、安価な費用で、この豪雨災害を緩和する機能があります。
また、巨大地震が発生すれば、地下鉄や電車は運休し、道路は車が渋滞して避難経路になり得ず、人口密度が高い都心の防災エリアは、帰宅困難者や避難者で埋め尽くされ、密集した人々にとって緊急かつ最も重要な要件は、自宅やさらに安全な場所への移動手段と食料（特に飲料水）の確保であり、本発明は、この飲料水が貯留されている防災エリアを提供します。 In today's big cities, the ground surface is covered with asphalt and concrete, losing water permeability, the buildings rise and the heat island phenomenon accelerates, and if external conditions are added here, thunderclouds are generated by updrafts and sudden heavy rain There is a danger of disaster.
In addition, the effects of global warming have been hit by unprecedented torrential rains and huge typhoons, and disaster prevention measures are an urgent issue.
However, a new large-capacity drainage facility is required to stop this torrential rain disaster, which requires enormous costs and a long time, but the present invention is very simple and inexpensive, and this heavy rain Has the ability to alleviate disasters.
