以下、図面を参照して、本発明に係る取水装置を詳細に説明する。   Hereinafter, a water intake apparatus according to the present invention will be described in detail with reference to the drawings.

図1は本発明に係る取水装置の概略説明図である。図示のように、本発明の取水装置100は、地下貯留部20に貯留された貯留水Wを地表に取水するための装置であって、装置内の上部には隔壁1が設けられており、この隔壁1によって槽形の装置内部が片側の点検領域2と反対側の取水領域3とに区画されている。そして、隔壁1の下端と装置内部の底面とが離隔して、点検領域2と取水領域3隔壁1の下方で連通し、この隔壁1の下方の内部領域は異物沈殿領域4となっている。 FIG. 1 is a schematic explanatory view of a water intake apparatus according to the present invention. As shown in the figure, the water intake device 100 of the present invention is a device for taking the stored water W stored in the underground storage part 20 to the ground surface, and the partition wall 1 is provided in the upper part of the device. The inside of the tank-shaped device is partitioned by the partition wall 1 into an inspection area 2 on one side and a water intake area 3 on the opposite side. Then, spaced apart and the lower end and inside the device bottom surface of the partition walls 1 is communicated with inspection region 2 and intake region 3 in the lower partition wall 1, the interior area below the partition wall 1 has a foreign matter precipitation area 4 .

点検領域2の外側壁には、地下貯留部20と取水装置100を接続する接続口5が形成されており、この接続口5には、地下貯留部20からの送水管21が差込み接続されている。また、点検領域2の下部には、異物捕集手段6が点検領域2の上部開口7(開閉可能な蓋8で閉じられた開口7)に対向して脱着可能に設けられており、この異物捕集手段6の上端は、隔壁1の下端よりも上に位置し、接続口5の下端よりも下に位置している。なお、異物捕集手段6の上端は、隔壁1の下端と同じ高さに位置していてもよい。   A connection port 5 that connects the underground storage unit 20 and the water intake device 100 is formed on the outer wall of the inspection area 2, and a water pipe 21 from the underground storage unit 20 is plugged into the connection port 5. Yes. A foreign matter collecting means 6 is provided at the lower part of the inspection area 2 so as to be detachable so as to face the upper opening 7 (opening 7 closed by the openable / closable lid 8) of the inspection area 2. The upper end of the collecting means 6 is located above the lower end of the partition wall 1 and is located below the lower end of the connection port 5. Note that the upper end of the foreign matter collecting means 6 may be located at the same height as the lower end of the partition wall 1.

異物捕集手段6は、水や微細な異物Sを通すけれども粗い異物Sは通さない所謂フィルター材からなるものであって、粗い異物Sが異物捕集手段6と隔壁1との間や異物捕集手段6と外側壁との間を通り抜けて隔壁1の下方へ移行することのないように、点検領域2の下部の横断面形状と略同じ平面形状を有するフィルター材が使用されており、このフィルター材によって点検領域2が上下に分断されている。 The foreign matter collecting means 6 is made of a so-called filter material that allows water or fine foreign matter S 1 to pass therethrough but does not allow coarse foreign matter S 2 to pass through. The coarse foreign matter S 2 is between the foreign matter collecting means 6 and the partition wall 1. In addition, a filter material having substantially the same planar shape as the cross-sectional shape of the lower part of the inspection region 2 is used so that it does not pass between the foreign matter collecting means 6 and the outer wall and move below the partition wall 1. The inspection area 2 is vertically divided by this filter material.

異物捕集手段6を構成するフィルター材としては、金属製又は合成樹脂製のメッシュ体、網体、連続発泡体、不織布など、種々のものが使用され、粒径が1mm以上の粗い異物Sを通過させないで捕集できるものが好ましく使用される。このフィルター材の外形状は、点検領域2の下部の横断面形状と略同じ平面形状を有する限り特に制限されるものではなく、例えば、ブロック形状、板形状、シート形状、籠形状など、様々な外形状とすることができる。 As the filter material constituting the foreign matter collecting means 6, various materials such as a metal or synthetic resin mesh, net, continuous foam, nonwoven fabric, etc. are used, and the coarse foreign matter S 2 having a particle diameter of 1 mm or more. Those that can be collected without passing through are preferably used. The outer shape of the filter material is not particularly limited as long as it has substantially the same planar shape as the cross-sectional shape of the lower part of the inspection region 2. For example, the filter material has various shapes such as a block shape, a plate shape, a sheet shape, and a saddle shape. It can be an outer shape.

隔壁1を挟んで点検領域2と反対側の取水領域3には、取水手段として取水ポンプ(不図示)に接続された取水管9が上方から挿入されており、取水ポンプを駆動すると、取水領域3内の貯留水が取水管9を通じて外部(地表)へ取水されるようになっている。そして、取水管9の下端は、異物沈殿領域4に沈殿している微細な異物Sを吸い上げないように、隔壁1の下端よりも上、つまり異物沈殿領域4の上方に位置している。 A water intake pipe 9 connected to a water intake pump (not shown) as a water intake means is inserted from above into the water intake area 3 on the opposite side of the inspection area 2 across the partition wall 1, and when the water intake pump is driven, the water intake area The stored water in 3 is taken to the outside (surface) through the intake pipe 9. The lower end of the water intake pipe 9 is located above the lower end of the partition wall 1, that is, above the foreign matter precipitation region 4 so as not to suck up the fine foreign matter S 1 that has settled in the foreign matter precipitation region 4.

なお、取水管9は、図1では取水領域3の上部開口を覆う蓋8を貫通して取水領域3に挿入されているが、取水領域3の外側壁上部を貫通して挿入してもよいし、取水領域3の上壁(開口がない上壁)を貫通して挿入してもよい。また、取水ポンプ(不図示)は、地上に設置してもよいし、地中に格納してもよいし、後述する実施形態の取水装置のように取水領域3の内部に設置してもよい。   In FIG. 1, the intake pipe 9 is inserted into the intake area 3 through the lid 8 that covers the upper opening of the intake area 3, but may be inserted through the upper portion of the outer wall of the intake area 3. Then, it may be inserted through the upper wall of the water intake region 3 (upper wall without opening). Further, the water intake pump (not shown) may be installed on the ground, stored in the ground, or installed inside the water intake area 3 as in the water intake device of the embodiment described later. .

一方、地下貯留部20は、家屋の屋根に降る雨水や排水溝を流れる雨水を導入して貯留できるものであればどのようなものでもよく、例えば、図1に示すような地下水槽や、図3,図4に示すような雨水貯留配管構造体などが、地下貯留部20として設けられる。図1に示す地下貯留部20(地下水槽)は、側壁上部にオーバーフロー管22を設けており、また、図3,図4に示す雨水貯留配管構造体200は、後述するように、堰部材205から溢れた過剰な貯留水Wが最も下流側の排水管203から排水されるので、取水装置100の外側壁上部(点検領域2と取水領域3のいずれか一方又は双方の外側壁上部)にはオーバーフロー管を設けなくてもよいが、地下貯留部20(地下水槽)や雨水貯留配管構造体200における貯留水Wの急激な増水に備えて、取水装置100の外側壁上部にオーバーフロー管を設け、過剰の貯留水Wを排出できるようにすることが望ましい。
なお、図3,図4に示す雨水貯留配管構造体200については後で詳しく説明する。
On the other hand, the underground storage unit 20 may be anything as long as it can introduce and store rainwater falling on the roof of a house or rainwater flowing through a drainage ditch, for example, a groundwater tank as shown in FIG. 3, a rainwater storage piping structure as shown in FIG. The underground storage part 20 (groundwater tank) shown in FIG. 1 is provided with an overflow pipe 22 at the upper part of the side wall, and the rainwater storage piping structure 200 shown in FIGS. Since the excessive stored water W overflowing from the drainage is drained from the drainage pipe 203 on the most downstream side, the upper part of the outer wall of the water intake device 100 (the upper part of the outer wall of either the inspection area 2 or the water intake area 3 or both) Although it is not necessary to provide an overflow pipe, an overflow pipe is provided at the upper part of the outer wall of the water intake device 100 in preparation for a sudden increase in the stored water W in the underground reservoir 20 (ground water tank) or the rainwater storage piping structure 200. It is desirable to be able to discharge excess stored water W.
The rainwater storage piping structure 200 shown in FIGS. 3 and 4 will be described in detail later.

以上のような構成の取水装置100では、取水ポンプ(不図示)を駆動して取水領域3の内部の貯留水を取水管9の下端から吸い上げて外部に取水すると、それに伴って地下貯留部20の貯留水Wが接続口5から点検領域2に流入し、流入した貯留水Wが異物捕集手段(フィルター材)6を通過する際に、貯留水Wに含まれる粗い異物Sが異物捕集手段6の上面で捕集、除去される。このとき、異物捕集手段6の上端は、隔壁1の下端よりも上(又は下端と同じ高さ)に位置し、接続口5の下端よりも下に位置するため、異物捕集手段6の上端が隔壁1の下端よりも下に位置する場合のように、隔壁1の下端と異物捕集手段6の上端との間から粗い異物Sが隔壁1の下方へ逃げたり、異物捕集手段6の上端が接続口5の下端よりも上に位置する場合のように、接続口5の下部が異物捕集手段6で塞がれて粗い異物Sが接続口5の下部に溜まったりすることがなく、確実に異物捕集手段6の上面で粗い異物Sを捕集して除去することが可能となる。そして、異物捕集手段6を通過した貯留水Wが取水領域3に移行するまでに、貯留水Wに含まれる微細な異物Sが隔壁1の下方の異物沈殿領域4に沈殿して除去され、取水領域3まで移行した異物を含まない貯留水Wが取水管9の下端から吸い上げられて装置外部に取水される。このとき、取水管9の下端は隔壁1の下端よりも上、つまり異物沈殿領域4の上方に位置しているので、異物沈殿領域4に沈殿している微細な異物Sを貯留水Wと一緒に吸い上げる心配はない。 In the water intake device 100 having the above-described configuration, when a water intake pump (not shown) is driven to suck up the stored water inside the water intake region 3 from the lower end of the water pipe 9 and take water outside, the underground storage unit 20 is accordingly accompanied. When the stored water W flows into the inspection area 2 from the connection port 5 and passes through the foreign matter collecting means (filter material) 6, the coarse foreign matter S 2 contained in the stored water W is captured by the foreign matter. It is collected and removed on the upper surface of the collecting means 6. At this time, the upper end of the foreign matter collecting means 6 is located above (or the same height as the lower end) of the partition wall 1 and below the lower end of the connection port 5. As in the case where the upper end is located below the lower end of the partition wall 1, the coarse foreign matter S 2 escapes from the space between the lower end of the partition wall 1 and the upper end of the foreign material collection means 6, or the foreign material collection means. As in the case where the upper end of 6 is located above the lower end of the connection port 5, the lower part of the connection port 5 is blocked by the foreign material collecting means 6, and the rough foreign material S 2 accumulates at the lower part of the connection port 5. it is not, it is possible to remove reliably collect coarse foreign matter S 2 at the upper surface of the foreign matter collecting unit 6. Then, until the stored water W that has passed through the foreign matter collecting means 6 moves to the water intake region 3, the fine foreign matter S 1 contained in the stored water W is settled and removed in the foreign matter precipitation region 4 below the partition wall 1. The stored water W that does not contain foreign substances transferred to the water intake area 3 is sucked up from the lower end of the water intake pipe 9 and taken out of the apparatus. At this time, since the lower end of the intake pipe 9 is located above the lower end of the partition wall 1, that is, above the foreign matter precipitation region 4, the fine foreign matter S 1 precipitated in the foreign matter precipitation region 4 is referred to as the stored water W. There is no worry about sucking up together.

また、この取水装置100は、装置内の上部の隔壁1により、装置内部を片側の点検領域2と反対側の取水領域3とに区画して、取水領域3に取水手段9(取水管)を設けているため、メンテナンスの際に取水領域3から取水手段9を取り除く必要がなく、点検領域2の上部の蓋8を開けて、上部開口7と対向して点検領域2に設けられた異物捕集手段(フィルター材)6を、上部開口7から簡単に取り出して掃除することができ、更に、点検領域2を通して異物沈殿領域4などの装置内部の掃除も簡単に行うことができるので、メンテナンスが容易である。そして、内部点検も点検領域2を通して容易に行うことができる。   Further, the water intake device 100 divides the inside of the device into a water intake region 3 on one side and a water intake region 3 on the opposite side by a partition wall 1 in the upper part of the device, and water intake means 9 (water intake pipe) is provided in the water intake region 3. Therefore, it is not necessary to remove the water intake means 9 from the water intake area 3 at the time of maintenance, the lid 8 on the upper part of the inspection area 2 is opened, and the foreign matter trapped in the inspection area 2 facing the upper opening 7 is collected. Since the collecting means (filter material) 6 can be easily taken out from the upper opening 7 and cleaned, and the inside of the apparatus such as the foreign substance precipitation area 4 can be easily cleaned through the inspection area 2, maintenance can be performed. Easy. The internal inspection can be easily performed through the inspection area 2.

なお、異物捕集手段6は、異物沈殿領域4を左右に分断するように、隔壁1の下方に設けることも可能であり、そのようにしても粗い異物Sを捕集することができる。 Incidentally, the foreign matter collecting means 6, so as to divide the foreign matter precipitation area 4 in the left-right, it is also possible to provide the lower partition wall 1, it is possible to collect such coarse foreign matter S 2 even in the.

図2は本発明に係る取水装置の具体的な一実施形態を示す断面図である。   FIG. 2 is a cross-sectional view showing a specific embodiment of the water intake device according to the present invention.

この実施形態の取水装置101は、T字状三方管継手11の上端の接続口11aと下端の接続口11bに、短い直管13の下端部と短い直管14の上端部をそれぞれ差込み接続し、U字状管継手12の左右上端の接続口12a,12bに、短い直管14の下端部と長い直管15の下端部をそれぞれ差込み接続することによって、図示のごとき縦長のU字管状のコンパクトな装置本体を形成したものであって、このU字管状の装置本体の内側の側壁(管壁)が前述の隔壁1に該当し、U字状管継手12の内側の側壁が該隔壁1の下端部分となっている。   In the water intake device 101 of this embodiment, the lower end portion of the short straight pipe 13 and the upper end portion of the short straight pipe 14 are respectively inserted and connected to the connection port 11a and the lower end connection port 11b of the T-shaped three-way pipe joint 11. By connecting the lower end of the short straight pipe 14 and the lower end of the long straight pipe 15 to the connection ports 12a and 12b at the upper left and right ends of the U-shaped pipe joint 12, respectively, a vertically long U-shaped tube as shown in the figure is obtained. A compact apparatus main body is formed, and an inner side wall (tube wall) of the U-shaped apparatus main body corresponds to the partition wall 1 described above, and an inner side wall of the U-shaped pipe joint 12 corresponds to the partition wall 1. It is the lower end part of.

そして、長い直管15とU字状管継手12の右上部の連続した内部領域は取水領域3となっており、直管13とT字状三方管継手11と直管14とU字状管継手12の左上部の連続した内部領域は点検領域2となっていて、これらの点検領域2と取水領域3は、隔壁1の下方、つまり、異物沈殿領域4となるU字状管継手12の下部で連通している。更に、直管13,15の上端には、蓋受部材10,10を介して蓋8,8が開閉可能に取付けられており、これらの蓋8,8によって点検領域2と取水領域3の上部開口7,7が閉じられている。また、T字状三方管継手11の側部の接続口11cは、地下貯留部からの送水管21を接続する前述の接続口5となっている。   And the continuous internal area | region of the upper right part of the long straight pipe 15 and the U-shaped pipe coupling 12 is the water intake area 3, and the straight pipe 13, the T-shaped three-way pipe coupling 11, the straight pipe 14, and the U-shaped pipe A continuous inner region at the upper left part of the joint 12 is an inspection region 2, and these inspection region 2 and water intake region 3 are below the partition wall 1, that is, the U-shaped pipe joint 12 that becomes the foreign matter precipitation region 4. It communicates at the bottom. Further, lids 8, 8 are attached to the upper ends of the straight pipes 13, 15 via lid receiving members 10, 10 so as to be openable and closable. Openings 7, 7 are closed. Moreover, the connection port 11c at the side portion of the T-shaped three-way pipe joint 11 is the above-described connection port 5 for connecting the water supply pipe 21 from the underground storage unit.

点検領域2における直管14の管内上部には、前述の異物捕集手段6(フィルター材)が点検領域2の上部開口7に対向して、点検領域2を上下に分断するように、保持部材16で脱着可能に取付けられており、この異物捕集手段6の上端は、隔壁1の下端よりも上に位置し、接続口11c(5)の下端よりも下に位置している。従って、送水管21から点検領域2に流入した貯留水が異物捕集手段6を通過するときに、前述したように、貯留水に含まれている粗い異物を異物捕集手段6の上面で確実に捕集して除去できるようになっている。なお、異物捕集手段6の上端は、隔壁1の下端と同じ高さに位置してもよい。   At the upper part of the straight pipe 14 in the inspection region 2, the holding member is arranged so that the foreign matter collecting means 6 (filter material) faces the upper opening 7 of the inspection region 2 and divides the inspection region 2 up and down. 16, the upper end of the foreign material collecting means 6 is located above the lower end of the partition wall 1, and is located below the lower end of the connection port 11c (5). Therefore, when the stored water that has flowed into the inspection area 2 from the water pipe 21 passes through the foreign matter collecting means 6, as described above, the coarse foreign matter contained in the stored water is reliably detected on the upper surface of the foreign matter collecting means 6. It can be collected and removed. Note that the upper end of the foreign matter collecting means 6 may be positioned at the same height as the lower end of the partition wall 1.

上記の保持部材16は、図2に示すように、垂直片の上端部を外側に直角に折り曲げて係止片を形成すると共に、垂直片の下端部を内側に直角に折り曲げて保持片を形成したものであって、直管14の上部内面に沿って該保持部材16を周方向に間隔をあけて複数個配置し、各保持部材16の係止片を直管14の上端とT字状三方管継手11の接続口11bの奥端当止部との隙間に挿入、係止させて各保持部材16を固定し、これらの保持部材16の内側に嵌め込まれた異物捕集手段6を各保持部材16の保持片で下方から保持することによって、異物捕集手段6を脱着可能に取付けるものである。このような保持部材16で異物捕集手段6を取付けると、異物捕集手段6を上方に引き上げるだけで簡単に取り出すことができるので、メンテナンスが更に容易になる。
なお、異物捕集手段6の保持部材は、点検領域2内で貯留水の流下を妨げることなく異物捕集手段6を脱着可能に保持できるものであれば、どのような構造のものでも使用可能である。また、異物捕集手段6を上方に引き上げるための取っ手を設けてもよい。その場合、取っ手の一端を異物捕集手段6に取り付け、他端を点検領域2の上部開口7付近に位置させることで、蓋8を開けて取っ手の他端を上方に引き上げるだけで、異物捕集手段6を上方に引き上げることができる。
As shown in FIG. 2, the holding member 16 is bent at the upper end of the vertical piece at a right angle to form a locking piece, and the lower end of the vertical piece is bent at a right angle to form a holding piece. A plurality of holding members 16 are arranged along the upper inner surface of the straight pipe 14 at intervals in the circumferential direction, and the locking pieces of each holding member 16 are formed in a T-shape with the upper end of the straight pipe 14. Each holding member 16 is fixed by being inserted into and locked in the gap between the connection end 11b of the three-way pipe joint 11b and the foreign matter collecting means 6 fitted inside these holding members 16 respectively. The foreign material collecting means 6 is detachably attached by being held from below by the holding piece of the holding member 16. When the foreign matter collecting means 6 is attached with such a holding member 16, the foreign matter collecting means 6 can be easily taken out simply by pulling it upward, so that maintenance is further facilitated.
The holding member of the foreign matter collecting means 6 can be of any structure as long as it can hold the foreign matter collecting means 6 so as to be removable without disturbing the flow of the stored water in the inspection area 2. It is. Moreover, you may provide the handle for pulling up the foreign material collection means 6 upwards. In that case, by attaching one end of the handle to the foreign matter collecting means 6 and positioning the other end in the vicinity of the upper opening 7 of the inspection area 2, the lid 8 is opened and the other end of the handle is lifted upward. The collecting means 6 can be pulled upward.

また、取水領域3には、取水手段として、取水ポンプPを途中に設けた取水管9が上部開口7の蓋8を通して挿入されており、取水ポンプPが取水領域3内に収容されている。そして、取水管9の下端は、異物沈殿領域4に沈殿している微細な異物を吸い上げないように、隔壁1の下端よりも上、つまり異物沈殿領域4の上方に位置している。従って、取水ポンプPを駆動すると、取水領域3の異物を含まない貯留水が取水管9から吸い上げられて、地上における貯留水の利用場所まで送水され、利用場所で有効に利用される。   Further, in the water intake area 3, a water intake pipe 9 provided with a water intake pump P as a water intake means is inserted through the lid 8 of the upper opening 7, and the water intake pump P is accommodated in the water intake area 3. The lower end of the water intake pipe 9 is located above the lower end of the partition wall 1, that is, above the foreign matter precipitation region 4 so as not to suck up fine foreign matter deposited in the foreign matter precipitation region 4. Therefore, when the intake pump P is driven, the stored water that does not contain foreign matter in the intake area 3 is sucked up from the intake pipe 9 and is sent to the place where the stored water is used on the ground, where it is effectively used.

取水装置101を構成するT字状三方管継手11、U字状管継手12、直管13,14,15、蓋8、蓋受部材10などは、いずれも塩化ビニル樹脂などの合成樹脂で成形されたものが好ましく使用される。   The T-shaped three-way pipe joint 11, the U-shaped pipe joint 12, the straight pipes 13, 14, 15, the lid 8, the lid receiving member 10, etc. constituting the water intake device 101 are all molded from a synthetic resin such as a vinyl chloride resin. Those made are preferably used.

この実施形態の取水装置101の接続口11c(5)には、地下貯留部として図3の概略断面図及び図4の概略平面図に示すような雨水貯留配管構造体200が接続されている。
この雨水貯留配管構造体200は、複数の雨水桝201を間隔をあけて地面に埋設し、起点に位置する雨水桝201に、屋根に降った雨を流入させる流入管202を接続すると共に、雨水桝201同士を排水管203によって流れ勾配をつけて、又は、流れ勾配をつけないで互いに連結し、終点に位置する雨水桝201の内部に突入した排水管203の先端に、底部に栓204を有する有底筒状の堰部材205を取付けたものであって、中間の雨水桝201には送水管21が接続されており、この送水管21が取水装置101の接続口11c(5)に差込み接続されるようになっている。なお、送水管21は、起点に位置する雨水桝201に接続してもよいし、雨水桝同士を連結する排水管203から分岐して設けてもよい。
A rainwater storage piping structure 200 as shown in the schematic cross-sectional view of FIG. 3 and the schematic plan view of FIG. 4 is connected to the connection port 11c (5) of the water intake device 101 of this embodiment as an underground storage part.
In this rainwater storage piping structure 200, a plurality of rainwater tanks 201 are embedded in the ground at intervals, and an inflow pipe 202 through which rain falls on the roof is connected to the rainwater tank 201 located at the starting point. The drainage pipes 203 are connected to each other with or without a flow gradient by the drainage pipe 203, and a stopper 204 is provided at the bottom of the drainage pipe 203 that has entered the rainwater tank 201 located at the end point. A bottomed cylindrical weir member 205 is attached, and a water supply pipe 21 is connected to an intermediate rainwater basin 201, and this water supply pipe 21 is inserted into the connection port 11c (5) of the water intake apparatus 101. Connected. In addition, the water pipe 21 may be connected to the rainwater tank 201 located at the starting point, or may be provided by branching from the drain pipe 203 that connects the rainwater tanks.

このような雨水貯留配管構造体200では、水面が堰部材205の上端開口の高さになるまで、貯留水W(雨水)が流入管202、終点の雨水桝201を除く各雨水桝201、各排水管203の内部に貯留され、この貯留水Wが送水管21を通って取水装置101の点検領域2に流入するようになっている。そして、この雨水貯留配管構造体200のメンテナンスを行うときは、堰部材205の底部の栓204を抜いて貯留水Wを終点の雨水桝201の内部へ流出させ、最も下流側の排水管203から排水することによって、雨水桝201同士を連結する排水管203(貯留管)を空にできるようになっている。
なお、終点の雨水桝201は、側壁や底壁に孔の開いた浸透桝でもよい。
In such a rainwater storage piping structure 200, each of the rainwater tanks 201 except the inflow pipe 202 and the rainwater tank 201 at the end point is stored in the stored water W (rainwater) until the water surface reaches the height of the upper end opening of the weir member 205. The water is stored in the drain pipe 203, and the stored water W flows into the inspection area 2 of the water intake device 101 through the water supply pipe 21. When the maintenance of the rainwater storage piping structure 200 is performed, the stopper 204 at the bottom of the weir member 205 is pulled out to let the stored water W flow into the rainwater tub 201 at the end point, and from the drain pipe 203 on the most downstream side. By draining, the drainage pipe 203 (storage pipe) that connects the rainwater tanks 201 can be emptied.
Note that the rainwater tub 201 at the end point may be a seepage tub having a hole in the side wall or the bottom wall.

この雨水貯留配管構造体200は、堰部材205から溢れた過剰な貯留水Wが最も下流側の排水管203から排水されるので、取水装置101の直管13の外側壁や直管15の外側壁上部にオーバーフロー管(不図示)を設けなくてもよいが、最も下流側の排水管203がない場合は、オーバーフロー管を取水装置101に設けて過剰の貯留水をオーバーフローさせることが必要になる。   In this rainwater storage piping structure 200, the excessive stored water W overflowing from the weir member 205 is drained from the drainage pipe 203 on the most downstream side, so that the outside wall of the straight pipe 13 of the water intake device 101 and the outside of the straight pipe 15. It is not necessary to provide an overflow pipe (not shown) in the upper part of the wall. However, if there is no drain pipe 203 on the most downstream side, it is necessary to provide an overflow pipe in the water device 101 to overflow the excess stored water. .

以上のような構成の取水装置101も、雨水貯留配管構造体200の送水管21から点検領域2に流入した貯留水が異物捕集手段(フィルター材)6を通過する際に、貯留水に含まれる粗い異物が異物捕集手段6の上面で確実に捕集、除去され、異物捕集手段6を通過した貯留水が取水領域3に移行するまでに、貯留水に含まれる微細な異物が隔壁1の下方の異物沈殿領域4(U字状管継手12の下部)に沈殿して除去される。そして、取水ポンプPを駆動すると、取水領域3まで移行した異物を含まない貯留水が取水管9の下端から吸い上げられ、地上の利用場所まで送水されて有効に利用される。   The water intake device 101 configured as described above is also included in the stored water when the stored water flowing into the inspection region 2 from the water supply pipe 21 of the rainwater storage piping structure 200 passes through the foreign matter collecting means (filter material) 6. Coarse foreign matter is reliably collected and removed on the upper surface of the foreign matter collecting means 6, and the fine foreign matter contained in the stored water is separated by the partition wall until the stored water that has passed through the foreign matter collecting means 6 moves to the water intake region 3. 1 is deposited and removed in the foreign substance precipitation region 4 (lower part of the U-shaped pipe joint 12) below 1. And when the intake pump P is driven, the stored water which does not contain the foreign material which moved to the intake area 3 is sucked up from the lower end of the intake pipe 9, and is sent to the ground use place and used effectively.

また、この取水装置101も、片側の点検領域2と反対側の取水領域3とに区画され、取水領域3に取水手段として取水ポンプPを有する取水管9が設けられているため、メンテナンスの際に取水領域3の取水手段を取り除かないで、点検領域2の上部の蓋8を開けて、異物捕集手段6を簡単に取り出して掃除することができ、点検領域2を通して更に異物沈殿領域4などの装置内部の掃除も簡単に行うことができるので、メンテナンスが容易である。そして、内部点検も点検領域2を通して容易に行うことができる。   In addition, this water intake device 101 is also divided into an inspection area 2 on one side and a water intake area 3 on the opposite side, and a water intake pipe 9 having a water intake pump P as a water intake means is provided in the water intake area 3. Without removing the water intake means in the water intake area 3, the lid 8 at the top of the inspection area 2 can be opened and the foreign matter collecting means 6 can be easily taken out and cleaned. Since the inside of the apparatus can be easily cleaned, maintenance is easy. The internal inspection can be easily performed through the inspection area 2.

更に、この取水装置101は、T字状三方管継手11、U字状管継手12、直管13,14,15などの配管部材を用いて、縦長のU字管状の装置本体を形成しているため、装置のコンパクト化を図ることができ、しかも、U字管状の装置本体は内面に引っ掛かりがないので、メンテナンスが一層容易になるという利点もある。   Further, the water intake device 101 uses a piping member such as a T-shaped three-way pipe joint 11, a U-shaped pipe joint 12, and straight pipes 13, 14, 15 to form a vertically long U-shaped tubular device body. Therefore, the apparatus can be made compact, and the U-shaped apparatus body has no advantage of being caught on the inner surface, so that there is an advantage that maintenance becomes easier.
