Description
本発明は、建築物の雨水利用設備に接続して雨水を分別する雨水配管構造に関する。 TECHNICAL FIELD The present invention relates to a rainwater piping structure that connects rainwater utilization facilities for buildings to separate rainwater.
従来、建築物の屋根等に配設された樋内を流れる雨水を取水して、該雨水を雨水貯留タンク内に貯留する雨水配管構造が種々提案されており、該雨水配管構造を用いることによって、土砂や塵埃等を多く含んだ降雨初期の雨水と、比較的汚れの少ない降雨中期以降の雨水と、を分別して、通常であればそのまま排水溝等に導水して排水してしまう降雨中期以降の雨水を貯留し、様々な用途に有効活用することで上水の節約が可能となる。 Conventionally, various rainwater piping structures for collecting rainwater flowing in a gutter arranged on a roof of a building and storing the rainwater in a rainwater storage tank have been proposed, and by using the rainwater piping structure, , After separating the rainwater in the early stages of rainfall that contains a large amount of earth and sand and the rainwater in the middle period of rain, which is relatively clean, and then drains it by directing it to the drainage ditch etc. It is possible to save clean water by storing the rainwater of and making effective use of it for various purposes.
かかる雨水配管構造として、例えば特許文献１（特開２０１４−１０９１４１号）には、所定の高さに取水用の貯留管路４に連通した越流部３ａと、底部に排水部２ｆ（オリフィス）と、を具備した一時貯留部２を備え、該一時貯留部２で一時的に雨水を貯留して排水部２ｆから異物を含む汚れた雨水を排水しつつ、汚れの少ない雨水を越流部３ａから貯留管路４に導水を可能とする雨水配管構造が開示されている。 As such a rainwater piping structure, for example, in Patent Document 1 (JP-A-2014-109141), an overflow portion 3a communicating with a storage pipe line 4 for water intake at a predetermined height and a drainage portion 2f (orifice) at a bottom portion are provided. And a temporary storage part 2 provided with the temporary storage part 2 for temporarily storing rainwater and draining dirty rainwater containing foreign matter from the drainage part 2f, while collecting less rainwater overflow part 3a. Discloses a rainwater piping structure that enables water to be transferred to the storage pipeline 4.
また、特許文献２（特開平４−２６５３２９号）には、下水管路１を貫通させる地下分水室２において、降雨初期の雨水を生活汚水の最高水位よりやや高く設けられた低位の堰３から越流させ、雨水滞水管路５に貯水を可能とする雨水配管構造が開示されている。 Further, in Patent Document 2 (Japanese Patent Laid-Open No. 4-265329), in the underground water diversion chamber 2 that penetrates the sewer pipe 1, the rainwater at the early stage of rainfall is provided with a low weir 3 that is slightly higher than the highest water level of domestic wastewater. There is disclosed a rainwater piping structure that allows water to be overflowed from the tank and stores water in the rainwater retaining pipe 5.
しかしながら、上記特許文献１の雨水配管構造では、降雨初期の雨水が排水部２ｆから排水される前に降雨中期以降の雨水が一時貯留槽２に流入すると、当該降雨中以降の雨水により降雨初期の雨水が攪拌され、異物を含んだ降雨初期の雨水と、比較的汚れの少ない降雨中期以降の雨水と、が混ざって流出管３に導水され、貯留管路４に貯留されてしまう問題があった。
また、上記特許文献２の雨水配管構造においても、降雨初期の雨水が下水管路１に流入することで水量が増加するが、該水量の増加に伴い、雨水の流速も増加するため水位の上昇は少なく、降雨初期の雨水を好適に低位の堰３から越流させ、貯留することが困難だった。
However, in the rainwater piping structure of Patent Document 1 described above, when the rainwater from the middle of the rainfall period flows into the temporary storage tank 2 before the rainwater in the early stages of drainage is drained from the drainage section 2f, the rainwater from the middle of the rainfall period causes the rainwater in the early stages of rainfall to start raining. There was a problem that the rainwater was agitated and mixed with the rainwater in the early stage of the rain containing foreign matter and the rainwater from the middle period of the rain, which was relatively clean, and was led to the outflow pipe 3 and stored in the storage pipe 4. .
Further, in the rainwater piping structure of Patent Document 2 as well, the amount of water increases by the flow of rainwater in the early stages of rainfall into the sewer pipe 1. However, as the amount of water increases, the flow rate of rainwater also increases and the water level rises. However, it was difficult to appropriately overflow the rainwater from the lower weir 3 and store it.
また、雨水配管構造は、土砂や塵埃等を多く含んだ降雨初期の雨水を分別して排水するものであるため、構造上汚れが溜りやすく、定期的なメンテナンスが必要となるものであるが、該メンテナンスを行うには多くの手間が必要となるという問題があった。 Further, since the rainwater piping structure separates and drains the rainwater in the early stage of rainfall containing a large amount of earth and sand and dust, dirt is liable to accumulate in the structure and periodic maintenance is required. There is a problem that a lot of trouble is required to perform maintenance.
ここで、雨水配管構造を用いた雨水の導水方法に着目すると、降雨初期の雨水と、降雨中期以降の雨水と、の分別を行う構造に問題があり、当該構造では確実かつ効率的な雨水の分別と、簡便なメンテナンスと、を行うことができないことは明らかであって、未だ改善の余地があった。 Here, when focusing on the method of conducting rainwater using the rainwater piping structure, there is a problem in the structure that separates the rainwater in the early stages of rain and the rainwater in the middle period of rain onwards. It is clear that separation and simple maintenance cannot be performed, and there is still room for improvement.
そこで、本発明は、上記問題に鑑みて、メンテナンスが容易で土砂や塵埃等の異物を多く含んだ降雨初期の雨水と、比較的汚れの少ない降雨中期以降の雨水と、を分別可能な雨水配管構造を提供することを目的とする。 Therefore, in view of the above problems, the present invention is a rainwater pipe which is easy to maintain and is capable of separating rainwater in the early stages of rainfall that contains a large amount of foreign matter such as earth and sand and dust, and rainwater in the middle period of rainfall after which there is relatively little dirt. It is intended to provide a structure.

The standing portion 15 is composed of at least one opening portion 15A and a closing portion 15B, and has a cross-sectional area A1 of the water conduit 21 shown in FIGS. 5 (a), (b) and (c) and the standing portion 15. It is desirable that the standing area A2 and the opening area A3 of the opening 15A be determined from the respective area ratios according to the amount of water introduced into the water conduit.
より具体的には、屋根面積約２００ｍ２の建屋に降雨する雨水が、内径約１００ｍｍの導水管路に導水されることを想定した場合、立設部１５の立設面積Ａ２が導水管路の断面積Ａ１に占める面積比（Ａ２／Ａ１）が０．１〜０．４であれば、立設部１５で降雨初期の雨水６１を堰き止め、かつ、降雨中期以降の雨水６３の取水も妨げられない。また、開口の開口面積Ａ３が立設部１５の立設面積Ａ２に占める面積比（Ａ３／Ａ２）が０．０５〜０．２５であれば効率的に初期雨水を排出することができる。 More specifically, when it is assumed that rainwater that rains on a building with a roof area of about 200 m 2 is conducted to a water conduit having an inner diameter of about 100 mm, the standing area A2 of the standing portion 15 is equal to that of the water conduit. If the area ratio (A2 / A1) occupying the cross-sectional area A1 is 0.1 to 0.4, the standing portion 15 blocks the rainwater 61 at the beginning of rainfall and also prevents the intake of rainwater 63 after the middle period of rainfall. I can't. If the area ratio (A3 / A2) of the opening area A3 to the standing area A2 of the standing portion 15 is 0.05 to 0.25, the initial rainwater can be efficiently discharged.
経路隔離壁１１は、必ずしも水平である必要はないため、立設部１５の上端を傾斜させて対応してもよい。このため、当該立設部１５の開口部１５Ａの下端が、越流経路１９の下端よりも下方に配置されている必要がある。これにより、降雨初期の雨水６１が越流経路１９に流入する前に、立設部１５の開口部１５Ａに雨水が流入して排水されるため、降雨初期の雨水６１が取水経路２３に流入することを好適に抑制することができる。 Since the path isolation wall 11 does not necessarily have to be horizontal, the upper end of the upright portion 15 may be inclined. Therefore, the lower end of the opening 15A of the upright portion 15 needs to be arranged below the lower end of the overflow path 19. Accordingly, before the rainwater 61 in the early stage of rainfall flows into the overflow path 19, the rainwater flows into the opening 15A of the standing portion 15 and is drained, so that the rainwater 61 in the early period of rainfall flows into the intake route 23. This can be appropriately suppressed.
なお、図１（ａ）及び（ｃ）では、開口部１５Ａを縦長のスリットとして表現しているが、本発明の効果を損なわず雨水を流すことのできる開口部であれば形状はこれに限定されるものではなく、例えば複数の孔を設けて所定の開口面積を備えたものであってもよいし、開口部１５Ａと閉鎖部１５Ｂとを連続して格子状を形成したものであってもよい。開口部１５Ａが複数設けられていれば、当該開口１５Ａに異物が詰まった場合でも排水経路１７が完全に閉鎖されることを抑制することができる。 1A and 1C, the opening 15A is expressed as a vertically long slit, but the shape is not limited to this as long as the opening allows rainwater to flow without impairing the effects of the present invention. Instead of the above, for example, a plurality of holes may be provided to have a predetermined opening area, or the opening 15A and the closing portion 15B may be continuously formed into a lattice shape. Good. If a plurality of openings 15A are provided, it is possible to prevent the drainage path 17 from being completely closed even when foreign matter is clogged in the openings 15A.
また、立設部１５が上流側に傾いていれば、該立設部１５によって木の葉等の比較的大きな異物を容易に堰き止めることができ、雨水貯留槽２０３への混入を更に防止することができる。なお、立設部１５から導水管路２１の間に突設部（図示せず）等を設けて異物を堰き止めてもよい。
立設部１５の形状を変更して構成した雨水配管構造１は後述にて詳細に説明する。
Further, if the standing portion 15 is inclined to the upstream side, the standing portion 15 can easily block relatively large foreign matter such as leaves, and can further prevent the foreign matter from entering the rainwater storage tank 203. it can. Note that a protrusion (not shown) or the like may be provided between the upright portion 15 and the water conduit 21 to block foreign matter.
The rainwater piping structure 1 configured by changing the shape of the standing portion 15 will be described later in detail.
更に、立設部１５は完全に固定される必要はなく、任意に取り外し可能とすれば、立設部の立設面積Ａ２が導水管路の断面積Ａ１に占める面積比（Ａ２／Ａ１）と、開口部の開口面積Ａ３が立設部の立設面積Ａ２に占める面積比（Ａ３／Ａ２）と、を任意に変更できるため、取水量及び排水量を調整することができる。
また、当該立設部１５に付着した汚れ等を洗浄して開口面積を維持するためのメンテナンス性も向上させることができる。なお、本管５１又は枝管５３の所定の位置に点検口（図示せず）を設けて、上記立設部１５の交換等のメンテナンスを補助する機構を設けてもよい。
Further, the standing portion 15 does not need to be completely fixed, and if it can be arbitrarily removed, the standing area A2 of the standing portion occupies the sectional area A1 of the water conduit (A2 / A1). Since the area ratio (A3 / A2) of the opening area A3 of the opening to the standing area A2 of the standing portion can be arbitrarily changed, the amount of water intake and the amount of drainage can be adjusted.
Further, it is possible to improve the maintainability for cleaning the dirt and the like adhering to the standing portion 15 to maintain the opening area. An inspection port (not shown) may be provided at a predetermined position of the main pipe 51 or the branch pipe 53 to provide a mechanism for assisting maintenance such as replacement of the standing portion 15.
２．雨水配管構造１内における雨水の流れ
次に、図２（ａ）及び（ｂ）を用いて本実施形態の雨水配管構造１内における雨水の流れ方について詳細に説明する。図２（ａ）及び（ｂ）は、本実施形態の雨水配管構造１内における雨水の流れ方を説明するものであって、図２（ａ）は、図１（ａ）（ｂ）（ｃ）に示す本管５１を断面視した模式図であり、図２（ｂ）は、図１に示す雨水配管構造１を上方から略鉛直方向下向きに見下げた場合に見える模式図である。
2. Flow of Rainwater in Rainwater Piping Structure 1 Next, the flow of rainwater in the rainwater piping structure 1 of the present embodiment will be described in detail with reference to FIGS. 2A and 2B. 2 (a) and 2 (b) illustrate how rainwater flows in the rainwater piping structure 1 of the present embodiment, and FIG. 2 (a) shows FIGS. 1 (a) (b) (c). 2 (b) is a schematic view seen when the rainwater piping structure 1 shown in FIG. 1 is viewed downward from above in a substantially vertical direction.
＜降雨初期の雨水６１＞
本実施形態の雨水配管構造１は、雨水導入口３に対して屋根等の樋から導管した雨水配管２０７を接続し、初期雨水排水口５に排水用配管２０９を接続し、更に取水用導水口７には、雨水利用設備２０１に導水するための雨水利用配管２１１を接続して使用される。降雨が始まると、降雨初期の雨水６１が屋根に当たり、屋根表面及び該屋根に配設された樋等に付着した土砂や塵埃等を含みつつ樋に接続された雨水配管２０７に流れる。
<Rainwater 61 at the beginning of rainfall>
In the rainwater piping structure 1 of the present embodiment, a rainwater piping 207 which is a conduit from a gutter such as a roof is connected to the rainwater introduction port 3, a drainage pipe 209 is connected to the initial rainwater drainage port 5, and a water intake port for intake. A rainwater utilization pipe 211 for guiding water to the rainwater utilization equipment 201 is connected to the water tank 7 and used. When the rainfall starts, the rainwater 61 at the beginning of the rainfall hits the roof and flows into the rainwater pipe 207 connected to the gutter while containing the earth and sand adhering to the roof surface and the gutter provided on the roof.
図２（ａ）及び（ｂ）に示すとおり、まず、屋根に配設された樋と接続された雨水配管２０７から降雨初期の雨水６１が雨水導入口３を介して導水管路２１に導水され、本雨水配管構造１内部に侵入し、立設部１５に当たって堰き止められる。上述したとおり、立設部１５には開口部１５Ａが備わっており、当該開口部１５Ａが所定の開口部の開口面積Ａ３を有することから、当該面積に応じた流量で降雨初期の雨水６１が排水経路１７に侵入し、初期雨水排水口５を介して排水用配管２０９に排水される。この時、土砂や塵埃等の微細なものは雨水と同時に開口部１５Ａを通過して排水用配管２０９に流れるが、例えば落ち葉等の比較的大きな異物は閉鎖部１５Ｂで堰き止めることができる。 As shown in FIGS. 2 (a) and 2 (b), first, rainwater 61 at the beginning of rainfall is introduced into the water conduit 21 through the rainwater inlet 3 from the rainwater pipe 207 connected to the gutter provided on the roof. , Enters the inside of the rainwater piping structure 1 and hits the standing portion 15 to be blocked. As described above, the standing portion 15 is provided with the opening portion 15A, and since the opening portion 15A has the opening area A3 of the predetermined opening portion, the rainwater 61 in the early stage of rainfall is drained at a flow rate according to the area. It enters the path 17 and is drained to the drainage pipe 209 through the initial rainwater drainage port 5. At this time, fine particles such as earth and sand and dust pass through the opening 15A at the same time as rainwater and flow into the drainage pipe 209, but relatively large foreign matter such as fallen leaves can be blocked by the closing portion 15B.
＜降雨中期以降の雨水６３＞
その後、継続して立設部１５の開口部１５Ａから雨水が排水経路１７に導水されるが、降雨が継続すると次第に雨水配管２０７から本雨水配管構造１内に導水される雨水の流量が当該開口部１５Ａを介して排水経路１７に導水される雨水の流量を上回り、立設部１５に堰き止められた雨水（降雨中期以降の雨水６３）が雨水導入口３から導水管路２１に貯留されて水位が上昇する。更に雨水配管２０７から本雨水配管構造１内に導水される雨水の流入量が増加し、水位が立設部１５の上端に達して越えると、降雨中期以降の雨水６３は越流経路１９に侵入し、取水経路２３を通り、取水用導水口７を介して雨水利用配管２１１に導水される。
<Rainwater 63 after the middle of rainfall>
After that, the rainwater is continuously guided to the drainage route 17 from the opening 15A of the standing portion 15, but if the rainfall continues, the flow rate of the rainwater introduced into the main rainwater piping structure 1 from the rainwater pipe 207 gradually increases. Rainwater (rainwater 63 after the middle of rainfall) that exceeds the flow rate of rainwater guided to the drainage route 17 via the portion 15A and is blocked by the standing portion 15 is stored in the water conduit 21 from the rainwater inlet 3. The water level rises. Further, when the inflow of rainwater introduced into the rainwater piping structure 1 from the rainwater pipe 207 increases and the water level reaches and exceeds the upper end of the standing portion 15, the rainwater 63 after the middle period of rainfall enters the overflow path 19. Then, the water is guided to the rainwater utilization pipe 211 through the water intake route 23 and the water intake port 7.
上記のとおり、本実施形態の雨水配管構造１を用いることで土砂や塵埃等を含む汚れた降雨初期の雨水６１と、比較的汚れの少ない降雨中期以降の雨水６３と、を分別した導水を達成することができる。 As described above, by using the rainwater piping structure 1 of the present embodiment, it is possible to separate the rainwater 61 in the early stage of rain, which is contaminated with earth and sand, and the like, and the rainwater 63 after the middle period of rain, which is relatively clean, to separate water. can do.
