Description

本発明は、流入した雨水を複数の排水先に排水する分水ます及びこれを用いた分水システムに関するものである。   The present invention relates to a diverter for draining inflow rainwater to a plurality of drainage destinations and a diversion system using the diverter.

従来、雨水を処理するための構造や処理方法などは種々提案されている（例えば、特許文献１〜３参照。）。また、実際に、図５ａ，図５ｂに示すような分水システム１００も既に提供されている。該分水システム１００にあっては、側溝１１１（又は雨水本管）の近傍に分水ます１０１が埋設されており、該分水ます１０１は、コンクリート製のます本体１０２を有している。そして、該分水ます本体１０２の側壁には、流入用排水管１１０を接続するための流入口１０３と、側溝１１１に連通する排水管を接続するための第１の流出口１０４と、槽などの浸透施設１１２に連通する排水管を接続するための第２の流出口１０５とが設けられている。前記第１の流出口１０４は、前記流入口１０３より低い位置に設けられ、前記第２の流出口１０５は、該流入口１０３と該第１の流出口１０４との間の高さ位置に設けられている。これにより、流入用排水管１１０を介して分水ます１０１に流入した雨水は、まず側溝１１１へ排水され、ゲリラ豪雨などで水量が増大し、分水ます１０１において第１の流出口１０４から側溝１１１へ流出する雨水の量よりも流入口１０３から該分水ます１０１に流入する雨水の量が多くなった際には適切かつ円滑に浸透施設１１２にも排水される。   Conventionally, various structures and treatment methods for treating rainwater have been proposed (see, for example, Patent Documents 1 to 3). In fact, a water distribution system 100 as shown in FIGS. 5a and 5b has already been provided. In the water diversion system 100, a water diverter 101 is embedded in the vicinity of a side groove 111 (or a rainwater main), and the diverter distiller 101 has a main body 102 made of concrete. Then, on the side wall of the diverter main body 102, an inlet 103 for connecting the inflow drain pipe 110, a first outlet 104 for connecting the drain pipe communicating with the side groove 111, a tank, etc. And a second outlet 105 for connecting a drain pipe communicating with the permeation facility 112. The first outlet 104 is provided at a position lower than the inlet 103, and the second outlet 105 is provided at a height position between the inlet 103 and the first outlet 104. It has been. As a result, the rainwater that has flowed into the diversion vessel 101 through the inflow drainage pipe 110 is first drained into the gutter 111, and the amount of water increases due to guerrilla heavy rain and the like. When the amount of rainwater flowing into the diverted water mass 101 from the inlet 103 becomes larger than the amount of rainwater flowing into the water 111, the water is appropriately and smoothly drained into the infiltration facility 112.

しかしながら、上記のコンクリート製分水ますにおいては、各開口が異なる高さに配置されており、各開口に接続される排水管が流入用であるか流出用であるかがあらかじめ決められている。このため、該分水ますの周りにおいて流入用排水管あるいは流出用排水管の配置が限定されてしまうことになり、従来構成の分水ますは配管設計の自由度が極めて低いという問題があった。一方、このような問題を解決するため、あらかじめ多種多様なコンクリート製分水ますを取り揃えようとすると、無駄が生じやすくなり、全体として製品コストが高騰してしまうという問題が生じる。   However, in the above-mentioned concrete water diverter, each opening is arranged at a different height, and it is determined in advance whether the drain pipe connected to each opening is for inflow or for outflow. For this reason, the arrangement of the inflow drain pipe or the outflow drain pipe is limited around the diverter, and the diverter of the conventional configuration has a problem that the degree of freedom in piping design is extremely low. . On the other hand, in order to solve such a problem, if an attempt is made to prepare a wide variety of concrete diverters in advance, waste is likely to occur, resulting in a problem that the product cost increases as a whole.

そこで、本発明は、配管設計の自由度が高い分水ます、及びこれを用いた分水システムを提供することを目的とする。   Therefore, an object of the present invention is to provide a water distribution system having a high degree of freedom in piping design and a water distribution system using the same.

本発明は、有底筒状のます本体を備え、該ます本体に接続された少なくとも一つの流入用排水管を介して該ます本体内に流入した雨水を、該ます本体に接続された複数の流出用排水管を介して該ます本体の外へ排水する分水ますであって、前記ます本体の側壁には、浸透機能を有する槽を除く排水先に接続されており、該排水先が最優先に排水されるべき排水先となるような流出用排水主管が接続される基準流出口と、前記流出用排水主管とは異なる流出用排水副管、及び流入用排水管がそれぞれ接続可能な複数の流出入兼用口と、が設けられており、さらに、該複数の流出入兼用口の下端は、該ます本体において前記基準流出口の下端より高い位置に設定され、かつ互いに同じ高さに設定されており、該流出入兼用口に接続された位置における流出用排水副管及び流入用排水管の各管底が、該基準流出口に接続された位置における流出用排水主管の管底より高い位置に配置され、かつ互いに同じ高さに配置され、さらに複数の流出入兼用口において一の流入用排水管が接続された流出入兼用口以外に、流出入兼用口が２以上あり、該流出入兼用口には少なくとも流出用排水副管が接続されており、該ます本体内において流入用排水管と流出用排水副管との間に連結管が接続されていないことを特徴とする分水ますである。また、前記流出入兼用口にあって、前記流出用排水副管及び前記流入用排水管のいずれも接続されない流出入兼用口には該流出入兼用口の開口を塞ぐキャップが装着されていてもよい。 The present invention includes a bottomed cylindrical main body, and rainwater flowing into the main body through at least one inflow drain pipe connected to the main body is supplied with a plurality of rainwaters connected to the main body. This is a divide that drains out of the main body through the drainage drain pipe, and the side wall of the main body is connected to a drainage destination excluding a tank having a permeation function. Multiple outlets that can be connected to a reference outlet to which a drainage drain main pipe to be drained preferentially is connected, an outlet drainage sub-pipe different from the drainage drain main pipe, and an inflow drain pipe And the lower ends of the plurality of inlet / outlet ports are set higher than the lower end of the reference outlet in the main body and set to the same height as each other. At the position connected to the inflow / outlet port. The bottoms of the outflow drainage sub-pipe and the inflow drainage pipe are arranged at a position higher than the bottom of the outflow drainage main pipe at the position connected to the reference outlet, and are arranged at the same height. Further, there are two or more inflow / outlet ports other than the inflow / outlet port to which one inflow drainage pipe is connected at a plurality of outflow / inlet ports, and at least the outflow drainage sub-tube is connected to the outflow / inlet port. In the main body, the divide is characterized in that no connecting pipe is connected between the inflow drain pipe and the outflow drain sub pipe. In addition, a cap that closes the opening of the inflow / outflow port may be attached to the outflow / inflow port that is connected to the outflow / inflow port, and neither the outflow drainage sub-pipe nor the inflow drainage tube is connected to. Good.

かかる構成にあって、前記分水ますに接続される流出用排水管のうち、最優先に排水されるべき排水先に繋がる流出用排水主管は、前記基準流出口に接続される。また、該分水ますに接続される流入用排水管は、配管に際して最も都合の良い位置の流出入兼用口が選択され、その流出入兼用口に接続される。さらに、前記流出用排水主管とは異なる流出用排水副管は、適宜、好適な位置の流出入兼用口が選択され、その流出入兼用口に接続される。ここで、複数の流出入兼用口は、前記基準流出口よりも高位に配されているため、前記流入用排水管によって分水ます内に案内された雨水は、まず前記基準流出口から外部へ排水されることとなる。また、流出入兼用口同士は互いに同じ高さに揃えられており、流入用であるか流出用であるかに関わらず排水管が接続可能となっているため、施工現場に応じて適宜配管設計されて、該分水ますに接続される。このように、本発明の分水ますは、最優先されるべき流出用排水主管への排水経路を確保しつつ、流出用排水副管及び流入用排水管に対する配管設計の自由度を高めることができる。なお、本発明にあって、流出用排水主管及び流出用排水副管は、流出用排水管に含まれるものであり、該流出用排水主管及び／又は該流出用排水副管を説明する際には、適宜、流出用排水管あるいは排水管ということがある。   In such a configuration, an outflow drainage main pipe connected to a drainage destination to be drained with the highest priority among the outflow drainage pipes connected to the water diverter is connected to the reference outlet. In addition, as the inflow drainage pipe connected to the diverter, an outflow / inlet port at a position most convenient for piping is selected and connected to the outflow / inlet port. Further, the outflow drain sub-pipe different from the outflow drain main pipe is appropriately selected as an outflow / inlet port at a suitable position and connected to the outflow / inlet port. Here, since the plurality of inlet / outlet ports are arranged higher than the reference outlet, the rainwater guided into the water diverter by the inflow drain pipe is first discharged from the reference outlet to the outside. It will be drained. In addition, the inflow / outlet ports are aligned at the same height, and drainage pipes can be connected regardless of whether they are for inflow or outflow. And connected to the basin. As described above, the water diverter of the present invention increases the degree of freedom in piping design for the drainage drainage sub-pipe and the drainage drainage pipe while securing the drainage route to the drainage drainage main pipe that should be given the highest priority. it can. In the present invention, the outflow drain main pipe and the outflow drain sub pipe are included in the outflow drain pipe, and when explaining the outflow drain main pipe and / or the outflow drain sub pipe Is sometimes referred to as an outflow drain or drain.

また、流入用排水管が接続された流出入兼用口と、流出用排水副管が接続された流出入兼用口とが対向した構成にあって、該流入用排水管が接続された流出入兼用口と該流出用排水副管が接続された流出入兼用口との離間距離Ｄは、該流入用排水管が接続された流出入兼用口の口径ｄに対して、Ｄ≧３ｄである構成が好ましい。   In addition, the inflow / outlet port to which the inflow drainage pipe is connected and the outflow / inflow port to which the outflow drainage sub pipe is connected are opposed to each other, and the inflow / outflow port to which the inflow drainage pipe is connected The distance D between the outlet and the inflow / outlet port to which the outflow drainage pipe is connected is such that D ≧ 3d with respect to the diameter d of the outflow / inlet port to which the inflow drainage pipe is connected. preferable.

ここで、流入用排水管が接続された流出入兼用口と、流出用排水副管が接続された流出入兼用口とが対向して配置された場合、該流入用排水管が接続された流出入兼用口から分水ます内に勢いよく流入した雨水が、基準流出口ではなく該流出用排水副管が接続された流出入兼用口に直接流入してしまうおそれがある。そこで、前記離間距離Ｄと前記口径ｄとを上記した関係とし、該流入用排水管が接続された流出入兼用口と該流出用排水副管が接続された流出入兼用口との離間距離を十分に確保することにより、基準流出口から排水可能な雨量状況にも関わらず該流入用排水管が接続された流出入兼用口から分水ます内に流入した雨水が該流出用排水副管が接続された流出入兼用口に直接流入してしまう、ことを防止できる。   Here, when the inflow / outlet port to which the inflow drainage pipe is connected and the outflow / inflow port to which the outflow drainage sub pipe is connected are opposed to each other, the outflow to which the inflow drainage pipe is connected There is a risk that rainwater that has flowed into the diversion chamber from the inlet / outlet directly flows into the outlet / outlet port connected to the outlet drainage sub-tube instead of the reference outlet. Therefore, the distance D and the diameter d are set as described above, and the distance between the inflow / outlet port connected to the inflow drainage pipe and the outflow / inflow port connected to the outflow drainage subpipe is defined as By ensuring that the rainwater that has flowed into the diversion outlet from the inlet / outlet port to which the inflow drainage pipe is connected, regardless of the amount of rain that can be drained from the reference outlet, It can be prevented that it directly flows into the connected inflow / outlet port.

また、前記ます本体内において、前記基準流出口にはオリフィスが配設されていることが好ましい。   Further, it is preferable that an orifice is disposed at the reference outlet in the main body.

かかる構成とすることにより、基準流出口から排水される雨水量を適宜調整することが可能となる。   By adopting such a configuration, it becomes possible to appropriately adjust the amount of rainwater drained from the reference outlet.

また、前記ます本体が、有底円筒状であることが好ましい。   Moreover, it is preferable that the said main body is a bottomed cylindrical shape.

かかる構成とすることにより、前記複数の流出入兼用口を該ます本体の側壁にバランス良く配置することが可能となり、排水管の配管設計に無理が生じにくい。   By adopting such a configuration, it becomes possible to arrange the plurality of inflow / outlet ports on the side wall of the main body in a well-balanced manner, and it is difficult for the drainage pipe piping design to become unreasonable.

さらに、本発明は、上記の分水ますを備えた分水システムであって、前記分水ますの流出入兼用口のいずれかに接続された流入用排水管には、上流から下流に向けて下方傾斜する管勾配が設定されていることを特徴とする分水システムである。   Furthermore, the present invention is a water diversion system comprising the above-mentioned diversion basin, wherein the inflow drainage pipe connected to one of the inflow / outflow ports of the diversion basin is directed from upstream to downstream. The water diversion system is characterized in that a downwardly inclined pipe gradient is set.

かかる構成とすることにより、最も雨水の逆流を防止すべき流入用排水管において、円滑に雨水を上流から下流へ流下させることが可能となる。   By adopting such a configuration, it becomes possible to smoothly flow rainwater from the upstream to the downstream in the inflow drainage pipe that should most prevent the backflow of rainwater.

また、前記分水ますの流出入兼用口のいずれかに接続された流入用排水管には、上流側の端部が下流側の端部より高い位置に配された屈曲形状の継手が配設されていてもよい。   In addition, the inflow drainage pipe connected to one of the outlet / outlet ports of the diverter is provided with a bent joint in which the end on the upstream side is located higher than the end on the downstream side. May be.

かかる構成とすることによっても、最も雨水の逆流を防止すべき流入用排水管において、円滑に雨水を上流から下流へ流下させることができる。   Even with this configuration, it is possible to smoothly flow rainwater from upstream to downstream in the inflow drainage pipe that should most prevent backflow of rainwater.

さらに、前記分水ますの流出入兼用口のいずれかに接続された流入用排水管には、有底筒状のます本体を備え、該ます本体の側壁に、下流側の開口と、該下流側の開口の下端より高い位置に下端が設定された上流側の開口とが設けられた排水ますが配設されていてもよい。   Further, the inflow drain pipe connected to one of the outlet / outlet ports of the diverter is provided with a bottomed cylindrical main body, and the downstream side opening and the downstream side of the main body side wall are provided. A drainage basin provided with an upstream opening having a lower end set at a position higher than a lower end of the side opening may be disposed.

かかる構成とすることによっても、最も雨水の逆流を防止すべき流入用排水管において、円滑に雨水を上流から下流へ流下させることができる。   Even with this configuration, it is possible to smoothly flow rainwater from upstream to downstream in the inflow drainage pipe that should most prevent backflow of rainwater.

さらに、前記ます本体の流出入兼用口のうち、流出用排水副管が接続されている流出入兼用口には、フィルタ又はスクリーンが取り付けられていてもよい。   Furthermore, a filter or a screen may be attached to the inflow / outlet port to which the outflow drainage sub-tube is connected among the outflow / inlet ports of the main body.

このように流出入兼用口にフィルタ又はスクリーンが取り付けられると、ゴミ等が流出用排水副管へ流入してしまうことを防ぐことができる。   When a filter or a screen is attached to the inflow / outlet port in this way, dust or the like can be prevented from flowing into the outflow drainage sub-pipe.

本発明の分水ますは、複数の流出入兼用口を備えており、該流出入兼用口には流入用排水管及び流出用排水管のいずれも接続可能であるため、配管設計の自由度が極めて高い。また、本発明の分水システムは、様々な施工現場に対応できる利点がある。   The water diverter of the present invention has a plurality of inflow / outflow ports, and both the inflow and outflow drainage pipes can be connected to the outflow / inflow ports, so that the degree of freedom in piping design is increased. Extremely expensive. Moreover, the water diversion system of this invention has the advantage which can respond to various construction sites.

以下、本発明の分水ます及び該分水ますを用いた分水システムを具体化した実施例を詳細に説明する。なお、本発明は、下記に示す実施例に限定されることはなく、適宜設計変更が可能である。   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments embodying a water diverter and a water diversion system using the water diverter according to the present invention will be described in detail below. In addition, this invention is not limited to the Example shown below, A design change is possible suitably.

図１ａ，図１ｂに示すように、分水ます１は、軸方向がほぼ鉛直方向とされた有底円筒状のます本体２を備えている。該ます本体２は、製造、加工が容易な樹脂製のものが好ましく、例えば硬質塩化ビニル樹脂製のものが強度も高く、特に好ましい。   As shown in FIGS. 1a and 1b, the water diverter 1 is provided with a bottomed cylindrical main body 2 whose axial direction is substantially vertical. The main body 2 is preferably made of a resin that is easy to manufacture and process. For example, a hard vinyl chloride resin is particularly preferable because of its high strength.

図１ａに示すように、前記ます本体２の側壁には、１つの基準流出口５と、３つの流出入兼用口６，７，８とが設けられている。さらに、図１ｂに示すように、該複数の流出入兼用口６，７，８の下端は、該ます本体２において前記基準流出口５の下端より高い位置に設定され、かつ流出入兼用口６，７，８同士で互いに同じ高さとなるように配置されている。なお、本実施例においては、図１ａに示すように、前記基準流出口５を基準にして、時計回りに第１流出入兼用口６、第３流出入兼用口８、及び第２流出入兼用口７の順に配置されている。   As shown in FIG. 1 a, a side wall of the main body 2 is provided with one reference outlet 5 and three inflow / outlets 6, 7, 8.

In the present embodiment, as shown in FIG. 1a, the first inflow / outlet port 6, the third inflow / outlet port 8, and the second inflow / outlet port are used clockwise with respect to the reference outflow port 5. Arranged in the order of the mouth 7.

また、前記ます本体２内においては、基準流出口５にオリフィス２０が取り付けられ、該基準流出口５からの排水量が調整されている。該オリフィス２０は、公知技術のものが好適に採用される。   Further, in the main body 2, an orifice 20 is attached to the reference outlet 5, and the amount of drainage from the reference outlet 5 is adjusted. As the orifice 20, a known technique is preferably employed.

次に、前記分水ます１を用いた分水システム３０を図２等に従って説明する。
図２に示すように、本実施例の分水システム３０は、前記分水ます１と、側溝１１１と、浸透施設１１２と、これらを繋ぐ排水管１５ａ〜１８ａとによって構成されている。 Next, a water diversion system 30 using the water diverter 1 will be described with reference to FIG.
As shown in FIG. 2, the water diversion system 30 of a present Example is comprised by the said water diverter 1, the gutter 111, the infiltration facility 112, and the drain pipes 15a-18a which connect these.

前記分水ます１の前記基準流出口５には、該基準流出口５から外向きに差し出された受口部１５を介して流出用排水主管１５ａが接続されている。そして、該流出用排水主管１５ａは、側溝１１１に接続されている。また、前記第１流出入兼用口６には、該第１流出入兼用口６から外向きに差し出された受口部１６を介して流入用排水管１６ａが接続されている。さらに、前記第３流出入兼用口８には、該第３流出入兼用口８から外向きに差し出された受口部１８を介して流入用排水管１８ａが接続されている。さらに、前記第２流出入兼用口７には、該第２流出入兼用口７から外向きに差し出された受口部１７を介して流出用排水副管１７ａが接続されている。そして、該流出用排水副管１７ａは、浸透施設１１２に接続されている。   An outflow drainage main pipe 15 a is connected to the reference outlet 5 of the water diverter 1 through a receiving portion 15 that is extended outward from the reference outlet 5. The outflow drainage main pipe 15 a is connected to the side groove 111. In addition, an inflow drain pipe 16 a is connected to the first inflow / outflow port 6 through a receiving port 16 that is extended outward from the first outflow / inflow port 6. Furthermore, an inflow drain pipe 18a is connected to the third outflow / inlet port 8 via a receiving port 18 that is extended outward from the third outflow / inlet port 8. Furthermore, an outflow drainage sub-pipe 17a is connected to the second outflow / inflow port 7 via a receiving port 17 that is extended outward from the second outflow / inflow port 7. The outflow drainage sub-pipe 17a is connected to the infiltration facility 112.

上記した分水システム３０の分水ます１にあって、流出入兼用口６，７，８に接続された位置における流出用排水副管１７ａ及び流入用排水管１６ａ，１８ａの各管底は、前記基準流出口５に接続された位置における流出用排水主管１５ａの管底より高い位置に配置され、かつ前記流出用排水副管１７ａ及び前記流入用排水管１６ａ，１８ａの各管底は互いに同じ高さに配置されている。また、前記ます本体２における第２流出入兼用口７には、前記浸透施設１１２へのゴミ等の混入を防止するため、フィルタ２２が取り付けられている。該フィルタ２２は、公知技術のスクリーンであってもよい。   Each of the bottoms of the outflow drainage sub-pipe 17a and the inflow drainage pipes 16a, 18a at the position connected to the outflow / inlet ports 6, 7, 8 in the diversion basin 1 of the diversion system 30 described above, The outlet drain sub-pipe 17a and the inlet drain pipes 16a and 18a are disposed at the same position as the bottom of the outlet drain main pipe 15a at the position connected to the reference outlet 5. Arranged at height. In addition, a filter 22 is attached to the second inflow / outlet port 7 in the main body 2 in order to prevent dust and the like from entering the infiltration facility 112. The filter 22 may be a known screen.

さらに、図３に示すように、前記分水ます１の流出入兼用口６，７，８に接続された流出用排水副管１７ａ及び流入用排水管１６ａ，１８ａは、それぞれ上流から下流に向けて下方傾斜する管勾配が設定されており、雨水が該流出用排水副管１７ａ及び該流入用排水管１６ａ，１８ａ内を逆流することなく安定して流下可能となっている。さらに、前記流入用排水管１６ａには、上流側の端部が下流側の端部より高い位置に配されたエルボ継手１９，１９が配設されている。このように、排水経路に落差が形成されることにより、雨水が該流入用排水管１６ａ内を逆流することなく安定して流下可能となる。なお、図３に示すエルボ継手１９，１９は、エルボ継手１９が二つ連接されて使用されているが、エルボ継手１９が単体で使用されてもよい。また、該エルボ継手１９は、適宜、流入用排水管１８ａ、あるいは流出用排水副管１７ａに配設されていてもよいし、前記流出用排水主管１５ａに配設されていてもよい。また、エルボ継手１９に代えて、屈曲形状をした他の継手が適宜使用されてもよい。   Furthermore, as shown in FIG. 3, the outflow drain sub-pipe 17a and the inflow drain pipes 16a, 18a connected to the outflow / inlet ports 6, 7, and 8 of the diverter 1 are respectively directed from upstream to downstream. Therefore, rainwater can flow stably without flowing back through the outflow drainage sub-pipe 17a and the inflow drainage pipes 16a and 18a. Further, the inflow drain pipe 16a is provided with elbow joints 19 and 19 in which the upstream end is disposed at a position higher than the downstream end. Thus, by forming a head in the drainage path, rainwater can flow stably without flowing back through the inflow drainage pipe 16a. In addition, although the elbow joints 19 and 19 shown in FIG. 3 are used by connecting two elbow joints 19, the elbow joint 19 may be used alone. Further, the elbow joint 19 may be appropriately disposed in the inflow drain pipe 18a or the outflow drain sub pipe 17a, or may be disposed in the outflow drain main pipe 15a. Further, in place of the elbow joint 19, another bent joint may be used as appropriate.

さらに、図４に示すように、前記分水ます１に接続された流入用排水管１８ａの他端には、排水ます２４が接続されている。さらに詳述すると、該排水ます２４は、有底筒状のます本体２５を備え、該ます本体２５の側壁には、下流側の開口２６と、該下流側の開口２６の下端より高い位置に下端が設定された上流側の開口２７とが設けられている。そして、該下流側の開口２６に該流入用排水管１８ａの他端が接続されている。かかる構成にあっても、排水経路に落差が形成されるため、雨水が該流入用排水管１８ａ内を逆流することなく安定して流下可能となる。なお、該排水ます２４は、適宜、流入用排水管１６ａ、あるいは流出用排水副管１７ａに配設されていてもよいし、前記流出用排水主管１５ａに配設されていてもよい。   Further, as shown in FIG. 4, a drainage drain 24 is connected to the other end of the inflow drainage pipe 18 a connected to the water diverter 1. More specifically, the drainage basin 24 includes a bottomed cylindrical main body 25, and the side wall of the main body 25 has a downstream opening 26 and a position higher than the lower end of the downstream opening 26. An upstream opening 27 having a lower end is provided. The other end of the inflow drain pipe 18a is connected to the downstream opening 26. Even in such a configuration, since a drop is formed in the drainage path, rainwater can flow stably without flowing back through the inflow drainage pipe 18a. The drainage basin 24 may be appropriately disposed in the inflow drainage pipe 16a or the outflow drainage sub pipe 17a, or may be disposed in the outflow drainage main pipe 15a.

図２〜図４に示すように、上記構成の分水ます１を用いた分水システム３０にあっては、流入用排水管１６ａ，１８ａを介して分水ます１のます本体２内に雨水が流入すると、まず基準流出口５を介して順次側溝１１１へ排水される。該基準流出口５には、オリフィス２０が取り付けられているので、側溝１１１へ排水される雨水量が適宜調整されている。   As shown in FIGS. 2 to 4, in the water diversion system 30 using the water diverter 1 having the above-described configuration, rainwater is contained in the main body 2 of the distiller 1 through the inflow drain pipes 16 a and 18 a. Is first drained to the side groove 111 sequentially through the reference outlet 5. Since the orifice 20 is attached to the reference outlet 5, the amount of rainwater drained into the side groove 111 is appropriately adjusted.

また、ゲリラ豪雨などで水量が増大し、分水ます１において基準流出口５から側溝１１１へ流出する雨水の量よりも、流入用排水管１６ａ，１８ａから該分水ます１に流入する雨水の量が多くなった際には、第２流出入兼用口７を介して浸透施設１１２へ排水される。ここで、流出用排水副管１７ａ及び流入用排水管１６ａ，１８ａには、管勾配が設定されていると共に、適宜エルボ継手１９や排水ます２４が配設されているため、雨水が所要の排水先に向かって円滑に流下する。   In addition, the amount of rainwater flowing into the diverter 1 through the drainage pipes 16a, 18a for inflow rather than the amount of rainwater flowing out from the reference outlet 5 into the gutter 111 in the diverter 1 due to an increase in water volume due to guerrilla heavy rain, etc. When the amount increases, the water is drained to the infiltration facility 112 through the second inflow / outlet port 7. Here, the outflow drainage sub-pipe 17a and the inflow drainage pipes 16a and 18a are provided with pipe gradients, and the elbow joint 19 and drainage basin 24 are appropriately disposed. Smoothly flow down.

これまでに述べたように、分水ます１には、流出入兼用口６，７，８が複数設けられ、該複数の流出入兼用口６，７，８の下端は、該ます本体２において前記基準流出口５の下端より高い位置に設定され、かつ流出入兼用口６，７，８同士で互いに同じ高さとなるように配置されているため、施工現場に応じて流出用排水副管１７ａ及び流入用排水管１６ａ，１８ａを接続することができる。したがって、該分水ます１を用いることにより、排水管１６ａ〜１８ａを配管する際の設計の自由度が極めて向上する。また、該分水ます１の分水ます本体２は、平面視円形状であって、複数の流出入兼用口６，７，８がます本体２の側壁にバランス良く配置されているため、上記配管設計に無理が生じにくい。   As described above, the diverter 1 is provided with a plurality of inflow / outlet ports 6, 7, and 8 and the lower ends of the inflow / outlet ports 6, 7, and 8 are located in the main body 2 Since it is set at a position higher than the lower end of the reference outlet 5 and the outlet / outlet ports 6, 7, 8 are arranged at the same height, the outlet drainage sub-pipe 17 a according to the construction site. The inflow drain pipes 16a and 18a can be connected. Therefore, the use of the diverter 1 greatly improves the degree of design freedom when piping the drain pipes 16a to 18a. In addition, since the main body 2 of the diverter 1 has a circular shape in plan view, a plurality of inflow / outlets 6, 7, 8 are arranged on the side wall of the main body 2 in a well-balanced manner. Unreasonable in piping design.

ところで、図１，図２に示すように、該分水ます１にあっては、流入用排水管１６ａが接続された第１流出入兼用口６と、流出用排水副管１７ａが接続された第２流出入兼用口７とが対向して配置されている。そして、該第１流出入兼用口６と該第２流出入兼用口７との離間距離Ｄは、該第１流出入兼用口６の口径ｄ（図１ｂ参照）に対して、Ｄ≧３ｄを満たす長さに設定されている。このように、第１流出入兼用口６の口径ｄに対して前記離間距離Ｄが十分に確保されていると、基準流出口５から排水可能な雨量状況にも関わらず該第１流出入兼用口６を介して流入した雨水が該第２流出入兼用口７へ直接流入してしまう、といったことがない。   By the way, as shown in FIG. 1 and FIG. 2, in the diverter 1, the first inflow / outlet port 6 to which the inflow drain pipe 16a is connected and the outflow drain sub pipe 17a are connected. The second inflow / outlet port 7 is disposed so as to face. The separation distance D between the first inflow / outflow port 6 and the second inflow / outlet port 7 is such that D ≧ 3d with respect to the diameter d of the first inflow / outlet port 6 (see FIG. 1b). The length is set to meet. As described above, when the separation distance D is sufficiently secured with respect to the diameter d of the first inflow / outflow port 6, the first outflow / inflow portion can be used regardless of the amount of rain that can be drained from the reference outlet 5. There is no such a case that rainwater flowing in through the port 6 directly flows into the second inflow / outlet port 7.

なお、上記分水システム３０は、雨水が基準流出口５を介して側溝１１１へ排水される構成であるが、該側溝１１１に代えて、雨水が基準流出口５を介して雨水本管へ排水される構成であってもよい。また、分水ます１に配設される流出入兼用口６，７，８の配設数は適宜変更可能である。仮に使用しない流出入兼用口がある場合、該流出入兼用口に開口を塞ぐキャップ等が装着されることとなる。また、上記分水システム３０にあって、上記管勾配、上記エルボ継手１９等の継手、あるいは上記排水ます２４は、最も逆流を防止すべき流入用排水管１６ａ，１８ａに少なくとも適用されていればよく、施工環境等によって適宜、流出用排水管１５ａ，１７ａにも適用される。   The water diversion system 30 is configured such that rainwater is drained to the side groove 111 via the reference outlet 5, but instead of the side groove 111, rainwater is drained to the rainwater main via the reference outlet 5. It may be configured. Further, the number of the inflow / outlet ports 6, 7, 8 disposed in the water diverter 1 can be appropriately changed. If there is an inflow / outlet port that is not used, a cap or the like that closes the opening is attached to the inflow / outlet port. In the water diversion system 30, the pipe gradient, the joint such as the elbow joint 19, or the drainage drain 24 is at least applied to the inflow drain pipes 16 a and 18 a that should prevent backflow most. It is often applied to the outflow drain pipes 15a and 17a as appropriate depending on the construction environment.
