Description

本発明は、家屋やビルディング等の建物の樋を流下する雨水を集めて貯留する装置に関する。更に詳しくは、地中に埋設された横型貯留槽に立設されたパイプ状の複数の縦型貯留槽を用いた雨水貯留装置に関するものである。   The present invention relates to an apparatus for collecting and storing rainwater flowing down a fence of a building such as a house or a building. More specifically, the present invention relates to a rainwater storage device using a plurality of pipe-shaped vertical storage tanks standing on a horizontal storage tank embedded in the ground.

従来、この種の雨水貯留装置として、雨水を貯留可能に構成された地下貯留槽と地上貯留槽とを備え、地上貯留槽が、地表に立てて並べられた複数のパイプ状の中空部材と、これらの中空部材の内部に形成された貯留室を互いに連通接続する連通管とを有する雨水貯留装置が開示されている（例えば、特許文献１参照。）。この雨水貯留装置では、複数のパイプ状の中空部材の内部が隔壁により区画されて中空部材の内部に貯留室と排出室が形成され、複数の中空部材のそれぞれの排出室が排水パイプにより互いに連通接続される。また地下貯留槽及び地上貯留槽に貯留された雨水が排水ポンプにより排出室に供給され、中空部材に設けられた排出バルブが排出室に供給された雨水を外部に排出可能に構成される。このように構成された雨水貯留装置では、貯留槽に貯留された雨水は排水ポンプを駆動することにより排水パイプを介して複数の中空部材における排出室に供給され、その中空部材に設けられた排出バルブを開放することにより雨水を比較的高い圧力で取出すことができる。また中空部材の大きさ及び本数を調整することにより、この雨水貯留装置が貯留し得る雨水の貯留量を比較的容易に増減できるようになっている。   Conventionally, as this type of rainwater storage device, provided with an underground storage tank and a ground storage tank configured to be able to store rainwater, the ground storage tank is a plurality of pipe-shaped hollow members arranged on the ground surface, There has been disclosed a rainwater storage device having a communication pipe that connects and connects the storage chambers formed inside these hollow members (see, for example, Patent Document 1). In this rainwater storage device, the interior of a plurality of pipe-shaped hollow members is partitioned by partition walls, and a storage chamber and a discharge chamber are formed inside the hollow member, and each discharge chamber of the plurality of hollow members communicates with each other by a drain pipe. Connected. Moreover, the rainwater stored in the underground storage tank and the ground storage tank is supplied to the discharge chamber by the drain pump, and the drain valve provided in the hollow member is configured to be able to discharge the rainwater supplied to the discharge chamber to the outside. In the rainwater storage device configured as described above, the rainwater stored in the storage tank is supplied to the discharge chambers of the plurality of hollow members through the drainage pipes by driving the drainage pump, and the discharge provided in the hollow member Rain water can be taken out at a relatively high pressure by opening the valve. Further, by adjusting the size and number of the hollow members, the amount of rainwater that can be stored by the rainwater storage device can be increased or decreased relatively easily.

しかし、上記従来の特許文献１に示された雨水貯留装置では、地上貯留槽の複数のパイプ状の中空部材の位置決め作業が比較的煩わしい不具合があった。具体的には、複数のパイプ状の中空部材を一定間隔になるように正確に設置しないと、複数の中空部材を連通管及び排水パイプで接続することが困難になるという問題点があった。また複数のパイプ状の中空部材を鉛直方向に立設した状態に保持することが難しく、各中空部材が鉛直線に対して様々な方向に不規則に傾いてしまい、複数の中空部材の見栄えを損なう問題点もあった。   However, the conventional rainwater storage device disclosed in Patent Document 1 has a disadvantage that the positioning operation of the plurality of pipe-shaped hollow members of the ground storage tank is relatively troublesome. Specifically, there is a problem in that it is difficult to connect the plurality of hollow members with the communication pipe and the drain pipe unless the plurality of pipe-shaped hollow members are accurately installed so as to have a constant interval. In addition, it is difficult to hold a plurality of pipe-shaped hollow members in a vertically erected state, and each hollow member tilts irregularly in various directions with respect to the vertical line, so that the appearance of the plurality of hollow members is improved. There was also a problem to lose.

Each of the pipes 11d is fixed, the lower part of the vertical storage tank 12 is inserted into the positioning short pipe 11d through the positioning hole 11b, and the gap between the positioning hole 11b and the outer peripheral surface of the vertical storage tank 12 is closed by the seal member 13. In addition, a communication hole 12 a is formed in a lower portion of the vertical storage tank 12 located in the horizontal storage tank 11.

本発明の第４の観点は、第１ないし第３の観点に基づく発明であって、更に図２及び図３に示すように、複数の縦型貯留槽１２のうち地上に突出する外周の一部又は全部に剛性ネット２６が掛け渡されたことを特徴とする。   A fourth aspect of the present invention is an invention based on the first to third aspects, and as shown in FIGS. 2 and 3, one of the outer circumferences of the plurality of vertical storage tanks 12 protruding above the ground. It is characterized in that a rigid net 26 is stretched over part or all.

本発明の第１の観点の装置では、複数のパイプ状の縦型貯留槽を、単一の横型貯留槽にその長手方向に間隔をあけて立設した状態で連通接続したので、上記縦型貯留槽の位置決め作業を容易に行うことができる。この結果、複数のパイプ状の縦型貯留槽を容易に設置することができる。また複数のパイプ状の縦型貯留槽の間隔が一定に保たれているので、隣接する縦型貯留槽の上部を上部連通管により連通接続する場合、同一長さの上部連通管を用いて比較的容易に連通接続することができる。   In the apparatus according to the first aspect of the present invention, a plurality of pipe-shaped vertical storage tanks are connected in communication with a single horizontal storage tank in a state of being spaced apart in the longitudinal direction. The positioning operation of the storage tank can be easily performed. As a result, a plurality of pipe-shaped vertical storage tanks can be easily installed. In addition, since the interval between multiple pipe-shaped vertical storage tanks is kept constant, when connecting the upper part of adjacent vertical storage tanks with the upper communication pipe, comparison is made using the upper communication pipe of the same length. Can be easily connected.

本発明の第２の観点の装置では、複数のパイプ状の縦型貯留槽を、各横型貯留槽にそれらの長手方向に間隔をあけて立設した状態でそれぞれ連通接続したので、各横型貯留槽毎における上記縦型貯留槽の位置決め作業を容易に行うことができる。この結果、各横型貯留槽毎に複数のパイプ状の縦型貯留槽を容易に設置することができる。また各横型貯留槽毎に複数のパイプ状の縦型貯留槽の間隔が一定に保持されるので、各横型貯留槽毎において隣接する縦型貯留槽の上部を上部連通管により連通接続する場合、同一長さの上部連通管を用いて比較的容易に連通接続することができる。また隣接する横型貯留槽を下部フレキシブル管により連通接続したので、各横型貯留槽の配置間隔が多少変化しても、その変化を下部フレキシブル管の伸縮により吸収できる。更に隣接する横型貯留槽を上部フレキシブル管により連通接続すれば、各横型貯留槽の配置間隔が多少変化しても、その変化を上部フレキシブル管の伸縮により吸収できる。   In the apparatus according to the second aspect of the present invention, a plurality of pipe-shaped vertical storage tanks are connected in communication with each horizontal storage tank in a state of being spaced apart in the longitudinal direction. The positioning operation of the vertical storage tank in each tank can be easily performed. As a result, a plurality of pipe-shaped vertical storage tanks can be easily installed for each horizontal storage tank. Also, since the interval between the plurality of pipe-shaped vertical storage tanks is kept constant for each horizontal storage tank, when connecting the upper part of the vertical storage tank adjacent to each horizontal storage tank through the upper communication pipe, Using the upper communication pipe having the same length, the communication connection can be made relatively easily. Further, since the adjacent horizontal storage tanks are connected to each other by the lower flexible pipe, even if the arrangement interval of the horizontal storage tanks is slightly changed, the change can be absorbed by the expansion and contraction of the lower flexible pipe. Further, if the adjacent horizontal storage tanks are connected to each other by the upper flexible pipe, even if the arrangement interval between the horizontal storage tanks is slightly changed, the change can be absorbed by the expansion and contraction of the upper flexible pipe.

本発明の第３の観点の装置では、横型貯留槽の上壁に位置決め孔を形成し、横型貯留槽の下壁に位置決め短管を固着し、縦型貯留槽の下部を横型貯留槽の上壁の位置決め孔を通って位置決め短管に挿入したので、各縦型貯留槽が横型貯留槽の上壁及び下壁に対し全て直角方向に延びて配設される。この結果、横型貯留槽をその上壁及び下壁が水平になるように地中に埋設すれば、全ての縦型貯留槽が鉛直方向に延びた状態で地上に突出するので、これらの縦型貯留槽の見栄えを損なうことはない。   In the apparatus according to the third aspect of the present invention, a positioning hole is formed in the upper wall of the horizontal storage tank, a positioning short pipe is fixed to the lower wall of the horizontal storage tank, and the lower part of the vertical storage tank is placed above the horizontal storage tank. Since each of the vertical storage tanks is inserted into the positioning short pipe through the positioning hole in the wall, the vertical storage tanks are all extended in the direction perpendicular to the upper and lower walls of the horizontal storage tank. As a result, if the horizontal storage tanks are buried in the ground so that the upper and lower walls thereof are horizontal, all the vertical storage tanks protrude above the ground in a state of extending in the vertical direction. The appearance of the storage tank is not impaired.

本発明の第４の観点の装置では、複数の縦型貯留槽のうち地上に突出する外周の一部又は全部に剛性ネットを掛け渡したので、バラ等のつる植物を剛性ネットに這わせて育成すれば、縦型貯留槽の周囲の見栄えを向上できるとともに、地球環境の改善を図ることもできる。   In the apparatus according to the fourth aspect of the present invention, since the rigid net is stretched over a part or all of the outer periphery protruding above the ground among the plurality of vertical storage tanks, vines such as roses are placed on the rigid net. If it grows up, it can improve the appearance around the vertical storage tank and improve the global environment.

次に本発明を実施するための形態を図面に基づいて説明する。
＜第１の実施の形態＞
図１に示すように、雨水貯留装置１０は、単一の横型貯留槽１１と、３本のパイプ状の縦型貯留槽１２とを備える。横型貯留槽１１は横方向に延びる直方体の箱状に形成され、水平面内の一方向に延びた状態で地中に埋設される。また縦型貯留槽１２は横型貯留槽１１にその長手方向に間隔をあけて立設した状態で連通接続され、横型貯留槽１１を地中に埋設したときに各縦型貯留槽１２は中央部から上部が地上にそれぞれ突出するように構成される。更に各縦型貯留槽１２の上面は閉止され、下面は開放される。なお、横型貯留槽１１は鋼板や繊維強化プラスチック（ＦＲＰ）等により形成され、縦型貯留槽１２は塩化ビニル製パイプやポリエチレン製パイプ等により形成される。また、縦型貯留槽１２の外径は２００〜６００ｍｍ、好ましくは３００〜５００ｍｍに設定され、縦型貯留槽１２の長さは２〜５ｍ、好ましくは３〜４ｍに設定される。更に横型貯留槽１１の高さは３００〜７００ｍｍ、好ましくは４００〜６００ｍｍに設定される。横型貯留槽１１の高さを３００〜７００ｍｍの範囲内に設定したのは、３００ｍｍ未満では３本の縦型貯留槽１２を横型貯留槽１１に立設したときに各縦型貯留槽１２が様々な方向に不規則に傾いてしまい、７００ｍｍを越えると地面１４の掘削作業性が悪くなるからである。 Next, an embodiment for carrying out the present invention will be described with reference to the drawings.
<First Embodiment>
As shown in FIG. 1, the rainwater storage device 10 includes a single horizontal storage tank 11 and three pipe-shaped vertical storage tanks 12. The horizontal storage tank 11 is formed in a rectangular parallelepiped box shape extending in the horizontal direction, and is embedded in the ground in a state extending in one direction in a horizontal plane. The vertical storage tanks 12 are connected to the horizontal storage tanks 11 in a state where they are erected at intervals in the longitudinal direction, and when the horizontal storage tanks 11 are buried in the ground, each vertical storage tank 12 has a central portion. The upper part protrudes from the ground. Furthermore, the upper surface of each vertical storage tank 12 is closed and the lower surface is opened. The horizontal storage tank 11 is formed of a steel plate, fiber reinforced plastic (FRP), or the like, and the vertical storage tank 12 is formed of a vinyl chloride pipe, a polyethylene pipe, or the like. Moreover, the outer diameter of the vertical reservoir 12 is set to 200 to 600 mm, preferably 300 to 500 mm, and the length of the vertical reservoir 12 is set to 2 to 5 m, preferably 3 to 4 m. Furthermore, the height of the horizontal storage tank 11 is set to 300 to 700 mm, preferably 400 to 600 mm. The reason why the height of the horizontal storage tank 11 is set within the range of 300 to 700 mm is that when the vertical storage tanks 12 are erected on the horizontal storage tank 11 when the vertical storage tanks 11 are less than 300 mm, the vertical storage tanks 12 are various. This is because the excavation workability of the ground surface 14 is deteriorated when it is inclined irregularly in any direction and exceeds 700 mm.

一方、横型貯留槽１１の上壁１１ａには、その長手方向に間隔をあけて３本の縦型貯留槽１２を挿通可能な３個の位置決め孔１１ｂがそれぞれ形成される。また横型貯留槽１１の下壁１１ｃ上面には、上記３個の位置決め孔１１ｂと孔心が一致しかつ縦型貯留槽１２を挿入可能な３個の位置決め短管１１ｄがそれぞれ固着される。縦型貯留槽１２の下部が位置決め孔１１ｂを通って位置決め短管１１ｄに挿入された状態で、位置決め孔１１ｂと縦型貯留槽１２外周面との隙間はシール部材１３により塞がれる。シール部材１３は、図１に詳しく示すように、位置決め孔１１ｂを囲むように横型貯留槽１１の上壁１１ａ上面に固着された嵌着用短管１３ａと、この嵌着用短管１３ａに嵌着される断面逆Ｕ字状の合成ゴム製のリング状パッキング１３ｂと、嵌着用短管１３ａより長くかつ大径に形成され嵌着用短管１３ａの外周面を囲むように横型貯留槽１１の上壁１１ａ上面に固着された抑え用短管１３ｃと、抑え用短管１３ｃ内周面と縦型貯留槽１２外周面とリング状パッキング１３ｂ上面とにより囲まれた空間に充填されるシーリング材１３ｄとを有する。なお、この実施の形態では、抑え用短管の内周面と縦型貯留槽の外周面とリング状パッキングの上面とにより囲まれた空間に、シーリング材ではなくモルタルを充填してもよい。   On the other hand, on the upper wall 11a of the horizontal storage tank 11, three positioning holes 11b are formed, through which the three vertical storage tanks 12 can be inserted at intervals in the longitudinal direction. Further, on the upper surface of the lower wall 11c of the horizontal storage tank 11, three positioning short pipes 11d whose hole centers coincide with the three positioning holes 11b and into which the vertical storage tank 12 can be inserted are fixed. In a state where the lower part of the vertical storage tank 12 is inserted into the positioning short pipe 11d through the positioning hole 11b, the gap between the positioning hole 11b and the outer peripheral surface of the vertical storage tank 12 is closed by the seal member 13. As shown in detail in FIG. 1, the seal member 13 is fitted to the fitting short tube 13a fixed to the upper surface of the upper wall 11a of the horizontal storage tank 11 so as to surround the positioning hole 11b, and the fitting short tube 13a. The ring-shaped packing 13b made of synthetic rubber having a reverse U-shaped cross section and the upper wall 11a of the horizontal storage tank 11 so as to be longer and larger in diameter than the fitting short tube 13a and surround the outer peripheral surface of the fitting short tube 13a The holding short tube 13c fixed to the upper surface, and the sealing material 13d filled in the space surrounded by the inner circumferential surface of the holding short tube 13c, the outer circumferential surface of the vertical storage tank 12, and the upper surface of the ring-shaped packing 13b. . In this embodiment, the space surrounded by the inner peripheral surface of the restraining short tube, the outer peripheral surface of the vertical storage tank, and the upper surface of the ring-shaped packing may be filled with mortar instead of the sealing material.

横型貯留槽１１に立設された３本の縦型貯留槽１２の下部には、横型貯留槽１１内に位置するように連通孔１２ａがそれぞれ形成される。これらの連通孔１２ａにより縦型貯留槽１２内部と横型貯留槽１１内部とが連通接続される。なお、上記連通孔１２ａは横型貯留槽１１の上部に位置するように縦型貯留槽１２に形成される。これは連通孔１２ａの上縁より上側の横型貯留槽１１内に空気が溜まるのを阻止するためである。ここで、横型貯留槽１１の下部に位置するように縦型貯留槽１２に孔（図示せず）を形成しておけば、横型貯留槽１１内の雨水１６の水位が低下したときに３本の縦型貯留槽１２内の雨水も同一水位で低下する。また３本の縦型貯留槽１２のいずれかには流入管１７が接続される。家屋やビルディング等の建物の屋根又は屋上に落下した雨水は樋（図示せず）などに集められ、この雨水は流入管１７を通って縦型貯留槽１２に導かれる。即ち、流入管１７の基端は樋に連通接続され、流入管１７の先端は右側の縦型貯留槽１２の上面に連通接続される。更に横型貯留槽１１の上壁１１ａには給水管１８の基端が横型貯留槽１１の下壁１１ｃ近傍まで延びて挿入され、この給水管１８の先端は横型貯留槽１１内及び縦型貯留槽１２内の雨水１６の利用先まで延びて設けられる。また給水管１８の途中には電動ポンプ１９が設けられ、この電動ポンプ１９は地面１４に架台２０を介して設置される。なお、３本の縦型貯留槽１２のうち左側の縦型貯留槽１２の中央部外周面には、給水短管２１の基端が接続される。この給水短管２１の先端には給水短管２１を開閉する蛇口２２が接続される（図１及び図２）。   A communication hole 12 a is formed in the lower part of the three vertical storage tanks 12 erected on the horizontal storage tank 11 so as to be located in the horizontal storage tank 11. The interior of the vertical storage tank 12 and the interior of the horizontal storage tank 11 are connected to each other through these communication holes 12a. The communication hole 12 a is formed in the vertical reservoir 12 so as to be positioned above the horizontal reservoir 11. This is to prevent air from accumulating in the horizontal reservoir 11 above the upper edge of the communication hole 12a. Here, if a hole (not shown) is formed in the vertical storage tank 12 so as to be positioned below the horizontal storage tank 11, three holes are provided when the level of the rainwater 16 in the horizontal storage tank 11 decreases. The rainwater in the vertical storage tank 12 also drops at the same water level. An inflow pipe 17 is connected to one of the three vertical storage tanks 12. Rainwater falling on the roof or roof of a building such as a house or building is collected in a fence (not shown) and the rainwater is guided to the vertical storage tank 12 through the inflow pipe 17. That is, the base end of the inflow pipe 17 is connected to the tub and the tip of the inflow pipe 17 is connected to the upper surface of the right vertical storage tank 12. Furthermore, the base end of the water supply pipe 18 is inserted into the upper wall 11a of the horizontal storage tank 11 so as to extend to the vicinity of the lower wall 11c of the horizontal storage tank 11, and the tip of the water supply pipe 18 is in the horizontal storage tank 11 and the vertical storage tank. 12 is provided to extend to the place of use of rainwater 16 in 12. In addition, an electric pump 19 is provided in the middle of the water supply pipe 18, and this electric pump 19 is installed on the ground 14 via a gantry 20. The proximal end of the short water supply pipe 21 is connected to the outer peripheral surface of the central portion of the left vertical storage tank 12 among the three vertical storage tanks 12. A faucet 22 that opens and closes the short water supply pipe 21 is connected to the tip of the short water supply pipe 21 (FIGS. 1 and 2).

一方、隣接する縦型貯留槽１２の上部は上部連通管２３により互いに連通接続される。具体的には、右側の縦型貯留槽１２の上部と中央の縦型貯留槽１２の上部が右側の上部連通管２３により連通接続され、中央の縦型貯留槽１２の上部と左側の縦型貯留槽１２の上部が左側の上部連通管２３により連通接続される。また３本の縦型貯留槽１２のいずれかの上部、この実施の形態では、３本の縦型貯留槽１２のうち右側の縦型貯留槽１２の上部には、排出管２４の基端が接続される。この排水管２４の先端は下水道や河川等（図示せず）に臨むように構成される。各縦型貯留槽１２の上部に溜まった空気は上部連通管２３及び排出管２４を通って縦型貯留槽１２外に排出され、各縦型貯留槽１２から溢れる雨水１６も上部連通管２３及び排出管２４を通って縦型貯留槽１２外に排出されるように構成される。   On the other hand, upper portions of adjacent vertical storage tanks 12 are connected to each other by an upper communication pipe 23. Specifically, the upper part of the right vertical storage tank 12 and the upper part of the central vertical storage tank 12 are connected to each other via the right upper communication pipe 23, and the upper part of the central vertical storage tank 12 and the vertical type of the left side are connected. The upper part of the storage tank 12 is connected in communication by an upper communication pipe 23 on the left side. In addition, in this embodiment, the base end of the discharge pipe 24 is above the right vertical storage tank 12 of the three vertical storage tanks 12 in the upper part of any one of the three vertical storage tanks 12. Connected. The tip of the drainage pipe 24 is configured to face a sewer, a river, etc. (not shown). Air accumulated in the upper part of each vertical storage tank 12 is discharged to the outside of the vertical storage tank 12 through the upper communication pipe 23 and the discharge pipe 24, and rainwater 16 overflowing from each vertical storage tank 12 is also discharged into the upper communication pipe 23 and It is configured to be discharged out of the vertical storage tank 12 through the discharge pipe 24.

更に３本の縦型貯留槽１２のうち地上に突出する外周の全部に剛性ネット２６が掛け渡される（図２及び図３）。即ち、剛性ネット２６により３本の縦型貯留槽１２のうち地上に突出する外周を一括して囲むように構成される。この剛性ネット２６としては、ステンレス鋼等の金属線材を格子状に編むことにより形成されたネット、合成樹脂で被覆した金属線材を格子状に編むことにより形成されたネット、硬質の合成樹脂線材を格子状に編むことにより形成されたネット等が挙げられる。なお、３本の縦型貯留槽のうち地上に突出する外周の全部ではなく、３本の縦型貯留槽のうち地上に突出する外周の一部に剛性ネットを掛け渡してもよい。具体的には、平板状の剛性ネットを３本の縦型貯留槽のうち地上に突出する外周の共通接線方向に延びて掛け渡してもよい。   Further, the rigid net 26 is stretched over the entire outer periphery of the three vertical storage tanks 12 protruding above the ground (FIGS. 2 and 3). That is, the rigid net 26 is configured to collectively surround the outer periphery of the three vertical storage tanks 12 that protrudes above the ground. As the rigid net 26, a net formed by knitting a metal wire such as stainless steel in a lattice shape, a net formed by knitting a metal wire covered with a synthetic resin in a lattice shape, a hard synthetic resin wire Examples thereof include a net formed by knitting in a lattice shape. Note that the rigid net may be stretched over a part of the outer periphery of the three vertical storage tanks that protrudes above the ground, instead of the entire outer periphery of the three vertical storage tanks that protrudes above the ground. Specifically, a plate-like rigid net may be extended and extended in the common tangential direction of the outer periphery protruding to the ground among the three vertical storage tanks.

このように構成された雨水貯留装置１０の組立方法を説明する。先ず工場で横型貯留槽１１、３本の縦型貯留槽１２等の各部品をそれぞれ製作する。次いで雨水貯留装置１０を組立てずに部品の状態で工場から設置現場まで搬送する。このとき各部品は比較的コンパクトであるので、大型トラックを用いずに小型トラックで搬送することができる。設置現場に到着すると、地面１４を所定の深さの直方体状に掘削し、この掘削部の底面を砂利や砂で締め固めた後、横型貯留槽１１を掘削部に挿入する。次に縦型貯留槽１２の下部を横型貯留槽１１の位置決め孔１１ｂに挿通した後に位置決め短管１１ｄに挿入して、横型貯留槽１１に３本の縦型貯留槽１２を立設する。そして横型貯留槽１１の位置決め孔１１ｂと縦型貯留槽１２外周面との隙間をシール部材１３により塞ぐ。具体的には、嵌着用短管１３ａにリング状パッキング１３ｂを嵌着した後に、抑え用短管１３ｃ内周面と縦型貯留槽１２外周面とリング状パッキング１３ｂ上面とにより囲まれた空間にシーリング材１３ｄを充填する。また架台２０上に電動ポンプ１９を設置し、この電動ポンプ１９の吸入口と横型貯留槽１１の上面とを給水管１８により連通接続するとともに、電動ポンプ１９の吐出口と雨水１６の利用先とを給水管１８により連通接続した後に、掘り出された土砂を掘削部と横型貯留槽１１との隙間や横型貯留槽１１の上面に埋め戻す。これにより横型貯留槽１１の全部及び３本の縦型貯留槽１２の下部が地中に埋設され、３本の縦型貯留槽１２の中央部から上部が地上にそれぞれ突出する。   A method for assembling the rainwater storage device 10 configured as described above will be described. First, each component such as the horizontal storage tank 11 and the three vertical storage tanks 12 is manufactured in the factory. Next, the rainwater storage device 10 is transported from the factory to the installation site in the state of parts without assembling. At this time, since each component is relatively compact, it can be transported by a small truck without using a large truck. When arriving at the installation site, the ground 14 is excavated into a rectangular parallelepiped shape having a predetermined depth, and the bottom surface of the excavation part is compacted with gravel or sand, and then the horizontal storage tank 11 is inserted into the excavation part. Next, the lower part of the vertical storage tank 12 is inserted into the positioning short tube 11 d after being inserted into the positioning hole 11 b of the horizontal storage tank 11, and the three vertical storage tanks 12 are erected on the horizontal storage tank 11. Then, the gap between the positioning hole 11 b of the horizontal storage tank 11 and the outer peripheral surface of the vertical storage tank 12 is closed by the seal member 13. Specifically, after the ring-shaped packing 13b is fitted to the fitting short tube 13a, the space surrounded by the inner surface of the suppressing short tube 13c, the outer circumferential surface of the vertical storage tank 12, and the upper surface of the ring-shaped packing 13b. The sealing material 13d is filled. In addition, an electric pump 19 is installed on the gantry 20, and the suction port of the electric pump 19 and the upper surface of the horizontal storage tank 11 are connected to each other by a water supply pipe 18, and the discharge port of the electric pump 19 and the destination of the rainwater 16 are used. Are connected through the water supply pipe 18, and then the excavated earth and sand are backfilled in the gap between the excavation part and the horizontal storage tank 11 or the upper surface of the horizontal storage tank 11. As a result, the entire horizontal storage tank 11 and the lower part of the three vertical storage tanks 12 are buried in the ground, and the upper part protrudes from the center of the three vertical storage tanks 12 to the ground.

上記設置作業では各縦型貯留槽１２の位置決め作業が容易になるので、３本の縦型貯留槽１２を容易に設置することができる。また各縦型貯留槽１２が横型貯留槽１１の上壁１１ａ及び下壁１１ｃに対し全て直角方向に延びて設けられるので、横型貯留槽１１をその上壁１１ａ及び下壁１１ｃが水平になるように地中に埋設することにより、全ての縦型貯留槽１２が鉛直方向に延びた状態で地上に突出する。この結果、３本の縦型貯留槽１２の見栄えを損なうことはない。更に、縦型貯留槽１２の地中への埋設長さは、２５〜４０％、好ましくは３０〜３５％に設定される。例えば、縦型貯留槽１２の全長が３ｍである場合、縦型貯留槽１２の地中への埋設長さは１ｍ程度であることが好ましい。縦型貯留槽１２の地中への埋設長さを２５〜４０％の範囲内に限定したのは、２５％未満では縦型貯留槽１２の起立安定性が損なわれ、４０％を越えると地面の掘削作業性が悪くなるからである。   In the above installation work, the positioning work of each vertical storage tank 12 is facilitated, so that the three vertical storage tanks 12 can be easily installed. Further, since each vertical storage tank 12 is provided so as to extend in a direction perpendicular to the upper wall 11a and the lower wall 11c of the horizontal storage tank 11, the upper wall 11a and the lower wall 11c of the horizontal storage tank 11 are horizontal. By embedding in the ground, all the vertical storage tanks 12 project to the ground in a state extending in the vertical direction. As a result, the appearance of the three vertical storage tanks 12 is not impaired. Further, the length of the vertical storage tank 12 embedded in the ground is set to 25 to 40%, preferably 30 to 35%. For example, when the total length of the vertical storage tank 12 is 3 m, the length of the vertical storage tank 12 embedded in the ground is preferably about 1 m. The reason why the length of the vertical storage tank 12 embedded in the ground is limited to the range of 25 to 40% is that when the vertical storage tank 12 is less than 25%, the standing stability of the vertical storage tank 12 is impaired. This is because the excavation workability of this becomes worse.

次に３本の縦型貯留槽１２のうち隣接する縦型貯留槽１２を上部連通管２３によりそれぞれ連通接続する。このとき３本の縦型貯留槽１２の間隔が一定に保たれているので、隣接する縦型貯留槽１２の上部を同一長さの上部連通管２３により比較的容易に連通接続することができる。その後、３本の縦型貯留槽１２のうち地上に突出する外周の全部に剛性ネット２６を掛け渡す。具体的には、剛性ネット２６を略楕円筒状に形成し、この剛性ネット２６を３本の縦型貯留槽１２に遊嵌した後に、剛性ネット２６を縦型貯留槽１２に固定する。この剛性ネット２６にはバラ等のつる植物を這わせて育成する。これにより縦型貯留槽１２の周囲の見栄えを向上できるとともに、地球環境の改善を図ることもできる。更に右側の縦型貯留槽１２の上面に流入管１７を連通接続し、左側の縦型貯留槽１２の上部に排出管２４を連通接続し、左側の縦型貯留槽１２の上下方向の中央に給水短管２１を介して蛇口２２を連通接続する。このような比較的簡単な作業で雨水貯留装置１０を設置できる。   Next, of the three vertical storage tanks 12, adjacent vertical storage tanks 12 are connected to each other through the upper communication pipe 23. At this time, since the interval between the three vertical storage tanks 12 is kept constant, the upper part of the adjacent vertical storage tanks 12 can be connected and connected relatively easily by the upper communication pipe 23 having the same length. . Thereafter, the rigid net 26 is stretched over the entire outer periphery of the three vertical storage tanks 12 protruding above the ground. Specifically, the rigid net 26 is formed in a substantially elliptic cylinder shape, and after the rigid net 26 is loosely fitted to the three vertical reservoirs 12, the rigid net 26 is fixed to the vertical reservoir 12. The rigid net 26 is grown by growing vines such as roses. Thereby, the appearance around the vertical storage tank 12 can be improved, and the global environment can be improved. Further, the inflow pipe 17 is connected to the upper surface of the right vertical storage tank 12, the discharge pipe 24 is connected to the upper part of the left vertical storage tank 12, and the vertical storage tank 12 on the left side is connected to the center in the vertical direction. The faucet 22 is connected in communication via the short water supply pipe 21. The rainwater storage device 10 can be installed by such a relatively simple operation.

なお、この実施の形態では、雨水貯留装置を部品で搬送して設置現場で組立てたが、雨水貯留装置が比較的小型であれば、雨水貯留装置を工場で組立てた後に、この組立てた雨水貯留装置を設置現場に搬送してもよい。この場合、現場での雨水貯留装置の設置作業時間を短縮することができる。   In this embodiment, the rainwater storage device is transported with parts and assembled at the installation site. However, if the rainwater storage device is relatively small, the assembled rainwater storage device is assembled after the rainwater storage device is assembled at the factory. The device may be transported to the installation site. In this case, the installation work time of the rainwater storage device at the site can be shortened.

このように設置された雨水貯留装置１０の動作を説明する。雨が降って、家屋やビルディング等の建物の屋根や屋上に落下した雨水１６は樋及び流入管１７を通って右側の縦型貯留槽１２に流入する。この雨水１６は先ず横型貯留槽１１及び３本の縦型貯留槽１２の下部に貯留され、更に雨水１６が流入すると、横型貯留槽１１から上方に突出する３本の縦型貯留槽１２に貯留されていく。このとき３本の縦型貯留槽１２内の空気は上部連通管２３及び排出管２４を通って縦型貯留槽１２外に排出される。この雨水貯留装置１０に貯留された雨水１６を庭の植木などへの散布に利用する場合には、電動ポンプ１９を作動させる。これにより横型貯留槽１１内の雨水１６が給水管１８を通って利用先に圧送されるので、この雨水１６を植木などに散布することができる。一方、雨水貯留装置１０内の雨水１６をバケツに汲む場合には、蛇口２２を操作して給水短管２１を開く。これにより３本の縦型貯留槽１２内の雨水１６のうち給水短管２１より上方に位置する雨水１６が蛇口２２から流出するので、この雨水１６をバケツで受ければよい。また降雨量が多い場合には、３本の縦型貯留槽１２から溢れる雨水１６は上部連通管２３及び排出管２４を通って下水道や河川等に排出される。   Operation | movement of the rainwater storage apparatus 10 installed in this way is demonstrated. When it rains, rainwater 16 that has fallen onto the roof or roof of a building such as a house or building flows into the vertical storage tank 12 on the right side through a gutter and an inflow pipe 17. This rainwater 16 is first stored in the lower part of the horizontal storage tank 11 and the three vertical storage tanks 12, and when rainwater 16 further flows in, it is stored in the three vertical storage tanks 12 protruding upward from the horizontal storage tank 11. It will be done. At this time, the air in the three vertical storage tanks 12 is discharged out of the vertical storage tank 12 through the upper communication pipe 23 and the discharge pipe 24. When the rainwater 16 stored in the rainwater storage device 10 is used for spraying on garden plants or the like, the electric pump 19 is operated. As a result, the rainwater 16 in the horizontal storage tank 11 is pumped to the user through the water supply pipe 18, so that the rainwater 16 can be sprayed on a plant or the like. On the other hand, when the rainwater 16 in the rainwater storage device 10 is drawn into a bucket, the water supply short pipe 21 is opened by operating the faucet 22. As a result, the rainwater 16 located above the short water supply pipe 21 out of the rainwater 16 in the three vertical storage tanks 12 flows out from the faucet 22, and the rainwater 16 may be received by a bucket. When the amount of rainfall is large, the rainwater 16 overflowing from the three vertical storage tanks 12 is discharged to the sewer or river through the upper communication pipe 23 and the discharge pipe 24.

＜第２の実施の形態＞
図５〜図８は本発明の第２の実施の形態を示す。図５〜図８において図１〜図４と同一符号は同一部品を示す。この実施の形態では、雨水貯留装置５０は、２個の横型貯留槽５１と、４本の縦型貯留槽１２とを備える。２個の横型貯留槽５１は同一形状に形成され、各横型貯留槽５１には、縦型貯留槽１２を２本ずつ立設できるようになっている。即ち、１個の横型貯留槽５１と２個の縦型貯留槽１２で１つの貯留ユニット６０が構成される。この実施の形態では、雨水貯留装置５０は２つの貯留ユニット６０を有する。各横型貯留槽５１は第１の実施の形態の横型貯留槽より長さが短くかつ上壁５１ａ上面の位置決め孔５１ｂ及び下壁５１ｃ上面の位置決め短管５１ｄの数が少ないけれども、これ以外は第１の実施の形態の横型貯留槽と略同一に構成される。また流入管１７は、２つの貯留ユニット６０のうち右側の貯留ユニット６０であって、２本の縦型貯留槽１２のうち右側の縦型貯留槽１２の上面に連通接続される。更に給水管１８は２つの貯留ユニット６０のうち左側の貯留ユニット６０の横型貯留槽５１の上面に挿入される。なお、給水管は２つの貯留ユニットの各横型貯留槽の上面に挿入してもよい。この場合、電動ポンプはそれぞれ１台ずつ合計２台必要となる。 <Second Embodiment>
5 to 8 show a second embodiment of the present invention. 5 to 8, the same reference numerals as those in FIGS. 1 to 4 denote the same components. In this embodiment, the rainwater storage device 50 includes two horizontal storage tanks 51 and four vertical storage tanks 12. The two horizontal storage tanks 51 are formed in the same shape, and two vertical storage tanks 12 can be erected in each horizontal storage tank 51. That is, one horizontal storage tank 51 and two vertical storage tanks 12 constitute one storage unit 60. In this embodiment, the rainwater storage device 50 has two storage units 60. Each horizontal storage tank 51 is shorter in length than the horizontal storage tank of the first embodiment and has a smaller number of positioning holes 51b on the upper surface of the upper wall 51a and positioning short pipes 51d on the upper surface of the lower wall 51c. It is comprised substantially the same as the horizontal storage tank of 1 embodiment. The inflow pipe 17 is the right storage unit 60 of the two storage units 60, and is connected to the upper surface of the right vertical storage tank 12 of the two vertical storage tanks 12. Further, the water supply pipe 18 is inserted into the upper surface of the horizontal storage tank 51 of the left storage unit 60 of the two storage units 60. In addition, you may insert a water supply pipe | tube in the upper surface of each horizontal storage tank of two storage units. In this case, a total of two electric pumps are required.

一方、上部連通管２３は、各横型貯留槽５１毎、即ち各貯留ユニット６０毎に、隣接する縦型貯留槽１２の上部をそれぞれ連通接続する。具体的には、２つの貯留ユニット６０のうち左側の貯留ユニット６０の２本の縦型貯留槽１２の上部が左側の上部連通管２３により接続され、右側の貯留ユニット６０の２本の縦型貯留槽１２の上部が右側の上部連通管１２により接続される。また排出管２４は４本の縦型貯留槽１２のいずれかの上部に接続される。この実施の形態では、排出管２４は左側の貯留ユニット６０の２本の縦型貯留槽１２のうち左側の縦型貯留槽１２の上部に接続される。また隣接する２つの横型貯留槽５１は下部フレキシブル管６１により互いに連通接続される（図５、図７及び図８）。具体的には、下部フレキシブル管６１は、２つの横型貯留槽５１に他端が対向するように一端がそれぞれ接続された２つのＬ字管６１ａと、これらのＬ字管６１ａの他端を連通接続する伸縮可能な単一の蛇腹管６１ｂとを有する（図７及び図８）。   On the other hand, the upper communication pipe 23 communicates and connects the upper portions of the adjacent vertical storage tanks 12 for each horizontal storage tank 51, that is, for each storage unit 60. Specifically, of the two storage units 60, the upper portions of the two vertical storage tanks 12 of the left storage unit 60 are connected by the left upper communication pipe 23, and the two vertical types of the right storage unit 60 are connected. The upper part of the storage tank 12 is connected by the upper communication pipe 12 on the right side. The discharge pipe 24 is connected to any one of the four vertical storage tanks 12. In this embodiment, the discharge pipe 24 is connected to the upper part of the left vertical storage tank 12 among the two vertical storage tanks 12 of the left storage unit 60. Two adjacent horizontal storage tanks 51 are connected to each other by a lower flexible pipe 61 (FIGS. 5, 7, and 8). Specifically, the lower flexible pipe 61 communicates two L-shaped pipes 61a each having one end connected to the two horizontal storage tanks 51 so that the other ends face each other, and the other ends of these L-shaped pipes 61a. It has a single bellows tube 61b that can be expanded and contracted (FIGS. 7 and 8).

隣接する横型貯留槽５１のうち隣接する縦型貯留槽１２の上部は上部フレキシブル管６２により連通接続される。具体的には、左側の横型貯留槽５１に立設された２本の縦型貯留槽１２のうち右側の縦型貯留槽１２の上部と、右側の横型貯留槽５１に立設された２本の縦型貯留槽１２のうち左側の縦型貯留槽１２の上部とが上部フレキシブル管６２により連通接続される。換言すれば、左側の貯留ユニット６０の２本の縦型貯留槽１２のうち右側の縦型貯留槽１２の上部と、右側の貯留ユニット６０の２本の縦型貯留槽１２のうち左側の縦型貯留槽１２の上部とが上部フレキシブル管６２により連通接続される。上部フレキシブル管６２は、隣接する縦型貯留槽１２に他端が対向するように一端がそれぞれ接続された２つのストレート管６２ａと、これらのストレート管６２ａの他端を連通接続する伸縮可能な単一の蛇腹管６２ｂとを有する。各縦型貯留槽１２の上部に溜まった空気は上部連通管２３、上部フレキシブル管６２及び排出管２４を通って縦型貯留槽１２外に排出され、各縦型貯留槽１２から溢れる雨水も上部連通管２３、上部フレキシブル管６２及び排出管２４を通って縦型貯留槽１２外に排出されるように構成される。   Of the adjacent horizontal storage tanks 51, the upper parts of the adjacent vertical storage tanks 12 are connected by an upper flexible pipe 62. Specifically, of the two vertical storage tanks 12 standing on the left horizontal storage tank 51, the upper part of the right vertical storage tank 12 and the two vertical storage tanks 51 standing on the right horizontal storage tank 51. Of the vertical storage tank 12 is connected to the upper part of the left vertical storage tank 12 by an upper flexible pipe 62. In other words, the upper part of the right vertical storage tank 12 of the two vertical storage tanks 12 of the left storage unit 60 and the left vertical of the two vertical storage tanks 12 of the right storage unit 60. The upper part of the mold storage tank 12 is connected in communication with the upper flexible pipe 62. The upper flexible pipe 62 includes two straight pipes 62a each having one end connected to the adjacent vertical storage tank 12 so that the other end faces each other, and a stretchable single pipe connecting the other ends of the straight pipes 62a. One bellows tube 62b. Air accumulated in the upper part of each vertical storage tank 12 is discharged to the outside of the vertical storage tank 12 through the upper communication pipe 23, the upper flexible pipe 62, and the discharge pipe 24, and rainwater overflowing from each vertical storage tank 12 is also in the upper part. It is configured to be discharged out of the vertical storage tank 12 through the communication pipe 23, the upper flexible pipe 62 and the discharge pipe 24.

また４本の縦型貯留槽１２のうち地上に突出する外周の全部に剛性ネット６６が掛け渡される（図６及び図７）。即ち、剛性ネット６６により４本の縦型貯留槽１２のうち地上に突出する外周を一括して囲むように構成される。なお、４本の縦型貯留槽のうち地上に突出する外周の全部ではなく、４本の縦型貯留槽のうち地上に突出する外周の一部に剛性ネットを掛け渡してもよい。具体的には、平板状の剛性ネットを４本の縦型貯留槽のうち地上に突出する外周の共通接線方向に延びて掛け渡してもよい。上記以外は第１の実施の形態と同一に構成される。   Moreover, the rigid net 66 is spanned over the whole outer periphery which protrudes on the ground among the four vertical storage tanks 12 (FIGS. 6 and 7). In other words, the rigid net 66 is configured to collectively surround the outer periphery of the four vertical storage tanks 12 protruding above the ground. In addition, you may hang a rigid net over a part of outer periphery which protrudes on the ground among four vertical storage tanks instead of the whole outer periphery which protrudes on the ground among four vertical storage tanks. Specifically, a flat rigid net may be extended and extended in the common tangential direction of the outer periphery of the four vertical storage tanks protruding to the ground. The configuration other than the above is the same as that of the first embodiment.

このように構成された雨水貯留装置５０の組立方法を説明する。先ず工場で２個の横型貯留槽５１、４本の縦型貯留槽１２等の各部品をそれぞれ製作する。次いで雨水貯留装置５０を組立てずに部品の状態で工場から設置現場まで搬送する。このとき各部品は比較的コンパクトであるので、大型トラックを用いずに小型トラックで搬送することができる。設置現場に到着すると、地面１４を所定の深さの直方体状に掘削し、この掘削部の底面を砂利や砂で締め固めた後、２個の横型貯留槽５１を一列に延びた状態で掘削部内に並べる。次に縦型貯留槽１２の下部を横型貯留槽５１の位置決め孔５１ｂに挿通した後に位置決め短管５１ｄに挿入して、各横型貯留槽５１に縦型貯留槽１２を２本ずつ立設する。そして横型貯留槽５１の位置決め孔５１ｂと縦型貯留槽１２外周面との隙間をシール部材１３により塞ぐ（図５）。また２個の横型貯留槽を下部フレキシブル管により連通接続する。更に架台２０上に電動ポンプ１９を設置し、この電動ポンプ１９の吸入口と横型貯留槽５１の上面とを給水管１８により連通接続するとともに、電動ポンプ１９の吐出口と雨水１６の利用先とを給水管１８により連通接続した後に、掘り出された土砂を掘削部と横型貯留槽５１との隙間や横型貯留槽５１の上面に埋め戻す。これにより２個の横型貯留槽５１の全部及び４本の縦型貯留槽１２の下部が地中に埋設され、４本の縦型貯留槽１２の中央部から上部が地上にそれぞれ突出する。   A method for assembling the rainwater storage device 50 configured as described above will be described. First, parts such as two horizontal storage tanks 51 and four vertical storage tanks 12 are manufactured in a factory. Next, the rainwater storage device 50 is transported from the factory to the installation site in the state of parts without assembling. At this time, since each component is relatively compact, it can be transported by a small truck without using a large truck. When arriving at the installation site, the ground 14 is excavated into a rectangular parallelepiped with a predetermined depth, and the bottom of the excavated portion is compacted with gravel or sand, and then the two horizontal storage tanks 51 are extended in a row. Line up in the club. Next, the lower part of the vertical storage tank 12 is inserted into the positioning short pipe 51 d after passing through the positioning hole 51 b of the horizontal storage tank 51, and two vertical storage tanks 12 are erected in each horizontal storage tank 51. And the clearance gap between the positioning hole 51b of the horizontal type | mold storage tank 51 and the vertical type storage tank 12 outer periphery is block | closed with the sealing member 13 (FIG. 5). The two horizontal storage tanks are connected to each other by a lower flexible pipe. In addition, an electric pump 19 is installed on the gantry 20, and the suction port of the electric pump 19 and the upper surface of the horizontal storage tank 51 are connected to each other by a water supply pipe 18. Are connected through the water supply pipe 18, and the excavated earth and sand are backfilled in the gap between the excavation part and the horizontal storage tank 51 and the upper surface of the horizontal storage tank 51. As a result, all of the two horizontal storage tanks 51 and the lower parts of the four vertical storage tanks 12 are buried in the ground, and the upper part protrudes from the center of the four vertical storage tanks 12 to the ground.

上記設置作業では各縦型貯留槽１２の位置決め作業が容易になるので、４本の縦型貯留槽１２を容易に設置することができる。また各縦型貯留槽１２が横型貯留槽５１の上壁１１ａ及び下壁１１ｃに対し全て直角方向に延びて設けられるので、各横型貯留槽５１をその上壁５１ａ及び下壁５１ｃが水平になるように地中に埋設することにより、全ての縦型貯留槽１２が鉛直方向に延びた状態で地上に突出する。この結果、４本の縦型貯留槽１２の見栄えを損なうことはない。更に２個の横型貯留槽５１の配置間隔が多少変化しても、その変化が下部フレキシブル管６１及び上部フレキシブル管６２の伸縮により吸収できるので、設置現場での雨水貯留装置５０の組立作業性を向上できる。   In the above installation work, the positioning work of each vertical storage tank 12 is facilitated, so that the four vertical storage tanks 12 can be easily installed. Further, since each vertical storage tank 12 is provided extending in a direction perpendicular to the upper wall 11a and the lower wall 11c of the horizontal storage tank 51, the upper wall 51a and the lower wall 51c of each horizontal storage tank 51 become horizontal. By embedding in the ground as described above, all the vertical storage tanks 12 project to the ground in a state of extending in the vertical direction. As a result, the appearance of the four vertical storage tanks 12 is not impaired. Furthermore, even if the arrangement interval of the two horizontal storage tanks 51 changes slightly, the change can be absorbed by the expansion and contraction of the lower flexible pipe 61 and the upper flexible pipe 62, so that the assembly workability of the rainwater storage device 50 at the installation site can be improved. It can be improved.

次に横型貯留槽５１毎に２本の縦型貯留槽１２を上部連通管２３により連通接続する。このとき横型貯留槽５１毎に２本の縦型貯留槽１２の間隔が一定に保たれているので、各横型貯留槽５１に用いられる上部連通管２３の長さを同一にすることができ、設置現場で上部連通管２３の長さを調整する手間を省くことができる。また左側の横型貯留槽５１に立設された２本の縦型貯留槽１２のうち右側の縦型貯留槽１２の上部と、右側の横型貯留槽５１に立設された２本の縦型貯留槽１２のうち左側の縦型貯留槽１２の上部とを上部フレキシブル管６２により連通接続する。その後、４本の縦型貯留槽１２のうち地上に突出する外周の全部に剛性ネット６６を掛け渡す。具体的には、剛性ネット６６を略楕円筒状に形成し、この剛性ネット６６を４本の縦型貯留槽１２に遊嵌した後に、剛性ネット６６を縦型貯留槽１２に固定する。更に右側の横型貯留槽５１に立設された２本の縦型貯留槽１２のうち右側の縦型貯留槽１２の上面に流入管１７を連通接続するとともに、この右側の縦型貯留槽１２の上下方向の中央に給水短管２１を介して蛇口２２を連通接続する。また左側の横型貯留槽５１に立設された２本の縦型貯留槽１２のうち左側の縦型貯留槽１２の上部に排出管２４を連通接続するとともに、この左側の縦型貯留槽１２の上下方向の中央に給水短管２１を介して蛇口２２を連通接続する。このような比較的簡単な作業で雨水貯留装置１０を設置できる。上記以外の組立方法は第１の実施の形態の組立方法と略同様であるので、繰返しの説明を省略する。   Next, for each horizontal storage tank 51, the two vertical storage tanks 12 are connected to each other through the upper communication pipe 23. At this time, since the interval between the two vertical storage tanks 12 is kept constant for each horizontal storage tank 51, the length of the upper communication pipe 23 used for each horizontal storage tank 51 can be made the same. It is possible to save the trouble of adjusting the length of the upper communication pipe 23 at the installation site. Further, of the two vertical storage tanks 12 erected on the left horizontal storage tank 51, the upper part of the right vertical storage tank 12 and the two vertical storages erected on the right horizontal storage tank 51. The upper part of the vertical storage tank 12 on the left side of the tank 12 is connected in communication with the upper flexible pipe 62. Thereafter, the rigid net 66 is spanned over the entire outer periphery of the four vertical storage tanks 12 protruding above the ground. Specifically, the rigid net 66 is formed in a substantially elliptic cylinder shape, and after the rigid net 66 is loosely fitted to the four vertical reservoirs 12, the rigid net 66 is fixed to the vertical reservoir 12. Further, an inflow pipe 17 is connected to the upper surface of the right vertical storage tank 12 out of the two vertical storage tanks 12 erected on the right horizontal storage tank 51, and the right vertical storage tank 12 A faucet 22 is connected to the center in the vertical direction via a short water supply pipe 21. A discharge pipe 24 is connected to the upper part of the left vertical storage tank 12 among the two vertical storage tanks 12 erected in the left horizontal storage tank 51, and the left vertical storage tank 12 A faucet 22 is connected to the center in the vertical direction via a short water supply pipe 21. The rainwater storage device 10 can be installed by such a relatively simple operation. Since the assembly method other than the above is substantially the same as the assembly method of the first embodiment, repeated description will be omitted.

なお、この実施の形態では、雨水貯留装置を部品で搬送して設置現場で組立てたが、雨水貯留装置が比較的小型であれば、雨水貯留装置の２つの貯留ユニットを工場で組立てた後に、この組立てた２つの貯留ユニットを他の部品とともに設置現場に搬送し、設置現場で２つの貯留ユニットを下部フレキシブル管及び上部フレキシブル管により連通接続してもよい。この場合、現場での雨水貯留装置の設置作業時間を短縮することができる。   In this embodiment, the rainwater storage device is transported with parts and assembled at the installation site, but if the rainwater storage device is relatively small, after assembling the two storage units of the rainwater storage device in the factory, The two storage units thus assembled may be transported together with other components to the installation site, and the two storage units may be connected to each other via the lower flexible pipe and the upper flexible pipe at the installation site. In this case, the installation work time of the rainwater storage device at the site can be shortened.

このように設置された雨水貯留装置５０の動作を説明する。雨が降って、家屋やビルディング等の建物の屋根や屋上に落下した雨水１６は樋及び流入管１７を通って右側の横型貯留槽５１に立設された２本の縦型貯留槽１２のうち右側の縦型貯留槽１２に流入する。この雨水１６は先ず２個の横型貯留槽５１及び４本の縦型貯留槽１２の下部に貯留され、更に雨水１６が流入すると、２個の横型貯留槽５１から上方に突出する４本の縦型貯留槽１２に貯留されていく。このとき４本の縦型貯留槽１２内の空気は上部連通管２３、上部フレキシブル管６２及び排出管２４を通って縦型貯留槽１２外に排出される。この雨水貯留装置１０に貯留された雨水１６を庭の植木などへの散布に利用する場合には、電動ポンプ１９を作動させる。これにより横型貯留槽５１内の雨水１６が給水管１８を通って利用先に圧送されるので、この雨水１６を植木などに散布することができる。一方、雨水貯留装置５０内の雨水１６をバケツに汲む場合には、蛇口２２を操作して給水短管２１を開く。これにより４本の縦型貯留槽１２内の雨水１６のうち給水短管２１より上方に位置する雨水１６が蛇口２２から流出するので、この雨水１６をバケツで受ければよい。また降雨量が多い場合には、４本の縦型貯留槽１２から溢れる雨水１６は上部連通管２３及び排出管２４を通って下水道や河川等に排出される。上記以外の動作は第１の実施の形態の動作と略同様であるので、繰返しの説明を省略する。   Operation | movement of the rainwater storage apparatus 50 installed in this way is demonstrated. Rainwater 16 that has fallen on the roof or rooftop of a building such as a house or building has fallen through two vertical storage tanks 12 erected in a horizontal storage tank 51 on the right side through a gutter and an inflow pipe 17. It flows into the vertical storage tank 12 on the right side. The rainwater 16 is first stored in the lower portions of the two horizontal storage tanks 51 and the four vertical storage tanks 12, and when the rainwater 16 further flows in, the four vertical storage tanks 51 project upward from the two horizontal storage tanks 51. It is stored in the mold storage tank 12. At this time, the air in the four vertical storage tanks 12 is discharged out of the vertical storage tank 12 through the upper communication pipe 23, the upper flexible pipe 62, and the discharge pipe 24. When the rainwater 16 stored in the rainwater storage device 10 is used for spraying on garden plants or the like, the electric pump 19 is operated. As a result, the rainwater 16 in the horizontal storage tank 51 passes through the water supply pipe 18 and is pumped to the user, so that the rainwater 16 can be sprayed on a plant or the like. On the other hand, when the rainwater 16 in the rainwater storage device 50 is drawn into a bucket, the water supply short pipe 21 is opened by operating the faucet 22. As a result, the rainwater 16 located above the short water supply pipe 21 out of the rainwater 16 in the four vertical storage tanks 12 flows out from the faucet 22, so that the rainwater 16 may be received by a bucket. When the amount of rainfall is large, the rainwater 16 overflowing from the four vertical storage tanks 12 is discharged to the sewer or river through the upper communication pipe 23 and the discharge pipe 24. Since the operation other than the above is substantially the same as the operation of the first embodiment, repeated description will be omitted.

なお、第１の実施の形態では、１個の横型貯留槽に３本の縦型貯留槽を立設し、第２の実施の形態では、１個の横型貯留槽に２本の縦型貯留槽を立設したが、１個の横型貯留槽に４本又は５本以上の縦型貯留槽を立設してもよい。また、第１の実施の形態では、単一の横型貯留槽を例示し、第２の実施の形態では、互いに連通接続された２個の横型貯留槽を例示したが、互いに連通接続された３個又は４個以上の横型貯留槽であってもよく、２本の縦型貯留槽を立設した横型貯留槽と３本の縦型貯留槽を立設した横型貯留槽を互いに連通接続してもよい。   In the first embodiment, three vertical storage tanks are erected in one horizontal storage tank, and in the second embodiment, two vertical storage tanks are provided in one horizontal storage tank. Although the tank is erected, four or five or more vertical reservoirs may be erected in one horizontal reservoir. In the first embodiment, a single horizontal storage tank is illustrated, and in the second embodiment, two horizontal storage tanks connected to each other are illustrated, but 3 connected to each other. The horizontal storage tank which installed two vertical storage tanks and the horizontal storage tank which installed three vertical storage tanks may communicate with each other. Also good.

また、第１の実施の形態では、隣接する縦型貯留槽の上部を上部連通管により連通接続したが、上部連通管を用いずに、各縦型貯留槽の上部にエア抜き孔を設けたり或いはエア抜き管を接続してもよい。更に第２の実施の形態では、各横型貯留槽毎に隣接する縦型貯留槽の上部を上部連通管により連通接続し、隣接する横型貯留槽のうち隣接する縦型貯留槽の上部を上部フレキシブル管により連通接続したが、上部連通管及び上部フレキシブル管を用いずに、各縦型貯留槽の上部にエア抜き孔を設けたり或いはエア抜き管を接続してもよい。   In the first embodiment, the upper parts of adjacent vertical storage tanks are connected to each other by the upper communication pipe. However, without using the upper communication pipe, an air vent hole is provided in the upper part of each vertical storage tank. Alternatively, an air vent pipe may be connected. Furthermore, in the second embodiment, the upper part of the vertical storage tank adjacent to each horizontal storage tank is connected by the upper communication pipe, and the upper part of the adjacent vertical storage tank among the adjacent horizontal storage tanks is flexible. Although connected through a pipe, an air vent hole may be provided in the upper part of each vertical storage tank or an air vent pipe may be connected without using the upper communication pipe and the upper flexible pipe.
