Description
本発明は、宅地や道路等より発生した雨水や生活廃水等の排水を好適に処理するための排水処理設備に関する。 The present invention relates to a wastewater treatment facility for suitably treating wastewater such as rainwater and domestic wastewater generated from residential land and roads.
近年、都市化による雨水流出率の増加やヒートアイランド現象による局地的な集中豪雨によって生じる浸水被害等の対応策として、宅地開発区域等には、貯留浸透槽等の雨水を一時的に貯留又は地中に浸透させることのできる施設の設置が義務付けられている。 In recent years, as countermeasures against the increase in rainwater runoff due to urbanization and inundation damage caused by localized torrential rain due to the heat island phenomenon, rainwater such as storage infiltration tanks is temporarily stored or landed in residential land development areas, etc. It is obliged to install a facility that can penetrate into it.
従来、このような貯留浸透施設では、宅地や道路等において降雨によって雨水が発生すると、まず貯留浸透槽に集水され、貯留浸透槽内に貯留されるとともに、順次地中に浸透させるようになっており、貯留浸透槽内の水が所定の水位に達する、即ち浸透速度より流入速度が勝り、貯留浸透槽の許容範囲を超えると水はオーバーフローによって下流側に流されるようになっている。 Conventionally, in such storage and infiltration facilities, when rainwater is generated due to rain on residential land or roads, water is first collected in the storage and infiltration tank, stored in the storage and infiltration tank, and gradually infiltrated into the ground. When the water in the storage permeation tank reaches a predetermined water level, that is, the inflow speed exceeds the permeation speed and exceeds the allowable range of the storage permeation tank, the water is caused to flow downstream due to overflow.
しかし、上述の如き従来の技術では、少量の水を処理する場合においても集水桝や貯留浸透槽等において一旦貯留してから浸透処理や放水処理等を行うため、豪雨等で水量が増加した際、少量の水を処理した際に貯留した分の水が既に貯留浸透槽内に貯留又は地中に浸透されてしまっているため、処理能力が求められる水量増加時に貯留又は浸透処理できる量が制限されてしまうという問題があり、十分な許容量を確保するためには、貯留浸透槽等の設備を大型化せざるを得なかった。 However, in the conventional technology as described above, even when a small amount of water is treated, the amount of water increased due to heavy rain or the like because it is once stored in a catchment tank or a storage infiltration tank and then subjected to an infiltration treatment or a water discharge treatment. At that time, the amount of water stored when processing a small amount of water has already been stored or infiltrated into the storage infiltration tank, so that the amount that can be stored or infiltrated when the amount of water is increased is required. There is a problem that it is limited, and in order to secure a sufficient tolerance, facilities such as a storage permeation tank have to be enlarged.
また、家屋の雨樋等から貯留浸透槽内に流入する排水には、雨樋に溜まった塵芥等が含有されており、この塵芥が排水とともに貯留浸透槽内に流入し、貯留浸透槽の底部に堆積するため、定期的に貯留浸透槽内を清掃する必要があるなどメンテナンスが煩わしいという問題があった。 In addition, the wastewater that flows into the storage infiltration tank from the rain gutters of the house contains the dust collected in the rain gutter, and this dust flows into the storage infiltration tank together with the drainage, and the bottom of the storage infiltration tank Therefore, there is a problem that maintenance is troublesome because the inside of the storage and permeation tank needs to be periodically cleaned.
そこで本発明は、上述の従来技術の問題を鑑み、水量増加時に好適に排水を処理することができ、維持管理も容易な排水処理設備の提供を目的とする。 In view of the above-described problems of the conventional technology, an object of the present invention is to provide a wastewater treatment facility that can appropriately treat wastewater when the amount of water increases and that can be easily maintained.

本発明に係る排水処理設備は、雨水及び／又は生活廃水等の排水が流れる流入管と、該流入管の下流側端部に接続された連結管と、該連結管を介して前記流入管に接続され、前記排水を下流側に流下させる下流側排水管と、前記連結管の下側又は周囲において貯水及び／又は排水が可能な集水部とを備え、前記連結管は、上部に１又は複数の流出孔を備え、前記連結管を流れる一定水量以上に達した分の水を前記流出孔より前記集水部内に流出させるようにしたことによって、水量が少ない時には排水を下流側に流下させて、集水部或いは集水部と連通した貯留浸透槽等の許容量を最大限に確保しておくことができるので、水量増加時に好適に対処することができ、しかも貯留浸透槽等の規模を小さくすることができコストの削減を図ることができる。 The wastewater treatment facility according to the present invention includes an inflow pipe through which drainage such as rainwater and / or domestic wastewater flows, a connecting pipe connected to a downstream end of the inflow pipe, and the inflow pipe via the connecting pipe. A downstream drainage pipe that is connected and allows the drainage to flow downstream, and a water collecting part that can store and / or drain water below or around the connection pipe, and the connection pipe is provided with 1 or A plurality of outflow holes are provided, and water corresponding to a certain amount or more flowing through the connecting pipe is allowed to flow out from the outflow holes into the water collecting part, so that when the amount of water is small, the drainage is caused to flow downstream. Therefore, it is possible to ensure the maximum allowable amount of the water collection section or the storage and permeation tank communicating with the water collection section, so that it is possible to appropriately cope with an increase in the amount of water, and the scale of the storage and permeation tank, etc. To reduce costs and reduce costs It can be.
また、集水部内或いは集水部と連通した集水桝や貯留浸透槽等に塵や異物が流入するのを防止することができ、煩わしい清掃等が不要となり、容易に管理することができる。 In addition, it is possible to prevent dust and foreign matter from flowing into a water collecting tank or a storage permeation tank in communication with the water collecting part or the water collecting part, so that troublesome cleaning or the like is not required and can be easily managed.
集水部内と連通し、連結管の流出孔より流出した流出水を下流側に流下させる流出水用排水管を備えたことによって、好適に分流することができる。 By providing the drainage pipe for effluent water that communicates with the inside of the water collecting section and flows down the effluent water that has flowed out from the outlet hole of the connecting pipe to the downstream side, it can be diverted appropriately.
流出水用排水管の下流側に貯留浸透槽を設けたことによって、流出水を好適に処理することができる。 By providing the storage permeation tank on the downstream side of the drain pipe for effluent water, the effluent water can be suitably treated.
流出孔は、透水可能な透水性部材で覆われたことによって、集水部や貯留浸透槽等に所定外形以上の塵や異物が堆積することを防止し、管理が容易になる。 Since the outflow hole is covered with a water-permeable member that allows water to pass therethrough, dust and foreign matters having a predetermined outer shape or more are prevented from accumulating in the water collection section, the storage and permeation tank, and the management becomes easy.
連結管は、その管径、設置勾配及び流出孔の位置によって、下流側に流下させる水量と、流出孔より流出させる水量とを調節することによって、下流側に流下させる水量と、流出孔より流出させる水量とを調節することによって、設置場所や周辺環境に応じて流量を制御することができる。 The connecting pipe adjusts the amount of water that flows down to the downstream side and the amount of water that flows out from the outflow hole according to the pipe diameter, installation gradient, and the position of the outflow hole, and the outflow from the outflow hole.

When the amount of water is low, drainage water such as rainwater is allowed to flow downstream to ensure the maximum capacity of the catchment. It is possible to cope with the increase appropriately.
次に、本発明に係る排水処理設備に関し図１〜図５について説明する。 Next, FIGS. 1-5 is demonstrated regarding the waste water treatment facility which concerns on this invention.
図１は、排水処理設備の概略を示している。 FIG. 1 shows an outline of a wastewater treatment facility.
この排水処理設備は、集水部を構成する集水桝１０と、雨樋１１からの雨水や生活廃水等の排水を流下させる流入管１２と、流入管１２の下流側端部に接続された連結管１３と、連結管１３を介して接続された下流側排水管１４と、貯留浸透槽１５に集水桝１０内の水を流下させるための流出水用排水管１６とを備えている。 This wastewater treatment facility is connected to a water collecting basin 10 constituting a water collecting section, an inflow pipe 12 for flowing rainwater such as rain water and domestic wastewater from the rain gutter 11, and a downstream end of the inflow pipe 12. A connecting pipe 13, a downstream drain pipe 14 connected via the connecting pipe 13, and an outflow water drain pipe 16 for allowing the water stored in the catchment basin 10 to flow into the storage permeation tank 15 are provided.
集水桝１０は、図２、図３に示すように、有底筒状の底ブロック１７と、側壁を構成する筒状の複数の側壁ブロック１８，１８…と、上面を閉鎖する天板ブロック１９とを備え、それらを順次地中に沈設することにより中空箱状に形成されている。 As shown in FIGS. 2 and 3, the water collecting basin 10 includes a bottomed cylindrical bottom block 17, a plurality of cylindrical side wall blocks 18, 18... Constituting a side wall, and a top plate block that closes the upper surface. 19 and are formed in a hollow box shape by sequentially sinking them into the ground.
この集水桝１０の側壁には、一方の側面に流入管１２が接続され、流入管１２と対向する位置に下流側排水管１４が接続され、側壁の底部には、貯留浸透槽１５と連通する流出水用排水管１６が接続されている。 An inflow pipe 12 is connected to one side surface of the side wall of the catchment basin 10, a downstream drain pipe 14 is connected to a position facing the inflow pipe 12, and the bottom portion of the side wall communicates with the storage permeation tank 15. The effluent water drain pipe 16 is connected.
また、この集水桝１０の底部には、インバートコンクリート２０が打設されている。 Invert concrete 20 is placed on the bottom of the water collecting basin 10.
天板ブロック１９には、管理用孔２１が設けられ、その上端面に開閉可能な蓋体２２が設置されている。 The top plate block 19 is provided with a management hole 21, and a lid 22 that can be opened and closed is installed on the upper end surface thereof.
連結管１３は、集水桝１０内に配置され、流入管１２と下流側排水管１４とを連結しており、集水桝１０は、連結管１３の下側において貯水又は排水が可能となっている。 The connecting pipe 13 is disposed in the catchment basin 10 and connects the inflow pipe 12 and the downstream drainage pipe 14, and the catchment basin 10 can store or drain water below the connecting pipe 13. ing.
尚、連結管１３と、流入管１２及び下流側排水管１４とは、それぞれ図示しない継手部材により連結されている。 The connecting pipe 13, the inflow pipe 12 and the downstream drain pipe 14 are connected by joint members (not shown).
この連結管１３は、図４に示すように、上部、即ち、管底部を除いた管外周面に多数の流出孔２３，２３…が形成されている。 As shown in FIG. 4, the connecting pipe 13 is formed with a large number of outflow holes 23, 23... At the top, that is, the outer peripheral surface of the pipe excluding the pipe bottom.
この連結管１３では、図５（ａ）に示すように、水は管底部を流れて下流側に流下するようになっているとともに、一定水量以上に達した分の排水を流出孔２３より集水部１０内に流出させるようになっている。 In this connecting pipe 13, as shown in FIG. 5 (a), water flows through the bottom of the pipe and flows down to the downstream side, and drainage that has reached a certain amount of water is collected from the outflow hole 23. It flows out into the water part 10.
即ち、連結管１３内に一定水量以上の水が流れると、図５（ｂ）に示すように、管内水位が流出孔２３，２３…が形成された位置にまで達し、一定水量以上に達した分の水が流出孔２３，２３…より集水桝１０内、即ち集水部内に流出されるようになっている。 That is, when water of a certain amount or more flows in the connecting pipe 13, the water level in the pipe reaches the position where the outflow holes 23, 23,... Are formed as shown in FIG. The water of the minute amount flows out from the outflow holes 23, 23... Into the water collecting basin 10, that is, into the water collecting portion.
従って、流出孔２３を形成する位置、即ち流出孔２３の管底からの距離ｈによって、流出孔２３より流出する水量を制御することができる。 Therefore, the amount of water flowing out of the outflow hole 23 can be controlled by the position where the outflow hole 23 is formed, that is, the distance h from the tube bottom of the outflow hole 23.
流出孔２３は、一辺が２ｍｍ以下の角形に形成され、排水に含まれる外形が２ｍｍ以上の塵や異物を集水部内に流出させないようになっている。 The outflow hole 23 is formed in a square shape with a side of 2 mm or less, so that dust and foreign matters having an outer shape of 2 mm or more contained in the drainage do not flow into the water collecting portion.
また、この連結管１３の管径、設置勾配、流出孔２３の大きさ等によって、下流側に流下させる水量と流出孔より流出して集水部内に流出する水量とを調整できるようになっている。 Further, the amount of water flowing down to the downstream side and the amount of water flowing out from the outflow hole and flowing out into the water collecting section can be adjusted by the pipe diameter of the connecting pipe 13, the installation gradient, the size of the outflow hole 23, and the like. Yes.
更には、下流側排水管１４の管径を連結管１３に対して小さくすることによって、下流側へ流下する水量を制御するようにしてもよい。 Furthermore, the amount of water flowing down to the downstream side may be controlled by making the pipe diameter of the downstream drain pipe 14 smaller than the connecting pipe 13.
この排水処理設備において、雨樋１１等から流下された排水は、流入管１２を通って連結管１３に至り、連結管１３内に流れる水量が一定水量以下であれば、下流側排水管１４を経て下流側に設置された汚水処理設備に流下される。 In this wastewater treatment facility, wastewater flowing down from the rain gutter 11 etc. reaches the connecting pipe 13 through the inflow pipe 12, and if the amount of water flowing into the connecting pipe 13 is less than a certain amount of water, After that, it flows down to the sewage treatment facility installed on the downstream side.
一方、連結管１３内に一定水量以上の水が流れた場合には、連結管１３内の水位が流出孔２３，２３…の位置まで達し、一定水量以上に達した分の水が連結管１３を流下する際に流出孔２３より集水桝１０内、即ち集水部に流出する。 On the other hand, when water of a certain amount or more flows in the connecting pipe 13, the water level in the connecting pipe 13 reaches the position of the outflow holes 23, 23. When the water flows down, it flows out from the outflow hole 23 into the water collecting basin 10, that is, into the water collecting portion.
その際、外形２ｍｍ以上の塵や異物は、流出孔２３を通過することができずに下流側に押し流されるようになっている。 At that time, dust and foreign matters having an outer diameter of 2 mm or more cannot pass through the outflow hole 23 and are pushed downstream.
従って、流出孔２３より流出した流出水は、流出孔２３を通過する際に濾過された状態になっている。 Accordingly, the outflow water flowing out from the outflow hole 23 is in a filtered state when passing through the outflow hole 23.
そして、この濾過された流出水ｗ１が流出水用排水管１６を通して貯留浸透槽１５に送り込まれ、貯留浸透槽１５内に貯留されるとともに、貯留浸透槽１５の底部又は側部より順次地中に浸透されていく。 The filtered effluent w1 is fed into the storage and penetration tank 15 through the effluent drain pipe 16 and stored in the storage and penetration tank 15, and sequentially into the ground from the bottom or side of the storage and penetration tank 15. It is permeated.
このとき、一定水量以下の状態では、排水は下流側に流れるために貯留浸透槽１５内は空の状態にあり、水量増加時はその処理容量を最大限に使用することができるようになっている。 At this time, in a state where the amount of water is below a certain amount of water, since the drainage flows downstream, the inside of the storage permeation tank 15 is empty, and when the amount of water increases, the treatment capacity can be used to the maximum. Yes.
一方、下流側に流下された排水ｗ２は、塵等を含有しているため、汚水処理設備に送り込まれ、塵や異物を分離除去した後、河川や放水池等に放流されるようになっている。 On the other hand, since the drainage w2 that has flowed downstream contains dust and the like, it is sent to a sewage treatment facility, and after separating and removing dust and foreign matter, it is discharged into rivers and drainage ponds. Yes.
尚、集水部は、内部に貯水可能な貯留型集水桝３０であってもよい。尚、上述の実施例と同一の部分には、同一符号を付して説明を省略する。 In addition, the water collecting part may be a storage-type water collecting tank 30 that can store water therein. In addition, the same code | symbol is attached | subjected to the part same as the above-mentioned Example, and description is abbreviate | omitted.
この集水桝３０は、図６、図７に示すように、中央の隔壁３１により隔てられた前室３２と後室３３とを有する本体ブロック３４と、本体ブロック３４の上面を閉鎖する天板ブロック３５と、天板ブロック３５の上部に設置された管理用孔３６，３６とを備え、前室３２内に貯留された排水が所定水位を超えると隔壁３１上部に形成された越流孔３７より後室３３内に流出するようになっている。 As shown in FIGS. 6 and 7, the water collecting basin 30 includes a main body block 34 having a front chamber 32 and a rear chamber 33 separated by a central partition wall 31, and a top plate for closing the upper surface of the main body block 34. A block 35 and management holes 36, 36 installed in the upper part of the top plate block 35, and an overflow hole 37 formed in the upper part of the partition wall 31 when the waste water stored in the front chamber 32 exceeds a predetermined water level. It flows out into the rear chamber 33 more.
また、本体ブロック３４には、各室３２，３３内をそれぞれ下端部に連通口３８が形成された状態に隔てる遮壁３９，４０が一体に形成されている。 Further, the body block 34 is integrally formed with shielding walls 39 and 40 that separate the interiors of the chambers 32 and 33 into a state in which a communication port 38 is formed at the lower end.
この集水桝３０の前室側側壁、即ち本体ブロック３４の側壁には、流入管１２が接続されている。 The inflow pipe 12 is connected to the front chamber side wall of the water collecting basin 30, that is, the side wall of the main body block 34.
一方、流入管１２の対向部側壁には、下流側排水管１４が接続され、流入管１２及び下流側排水管１４が連結管１３を介して連結されている。 On the other hand, a downstream drainage pipe 14 is connected to the opposite side wall of the inflow pipe 12, and the inflow pipe 12 and the downstream drainage pipe 14 are connected via a connecting pipe 13.
連結管１３は、図４に示す上述の連結管と同様に形成され、この連結管１３を流れる排水が一定水量以上に達した場合、一定水量以上に達した分の水が流出孔２３より集水桝３０内、即ち前室３２内に流出するようになっている。 The connecting pipe 13 is formed in the same manner as the above-described connecting pipe shown in FIG. 4, and when the drainage flowing through the connecting pipe 13 reaches a certain amount of water, the water that has reached the certain amount of water is collected from the outflow hole 23. It flows out into the water tank 30, that is, into the front chamber 32.
また、この集水桝３０は、底部に水よりも比重の重い泥質や異物を除去するための分離手段４１を備えている。 Further, the water collecting basin 30 is provided with separation means 41 for removing mud and foreign matters having a specific gravity heavier than water at the bottom.
この分離手段４１は、汚水処理設備に連通された汚水排水管４２と、該汚水排水管４２と前室３２及び後室３３の底部とを連通する排水口４３，４３とを備え、各室３２，３３に貯留された排水に含有された水より比重の重い泥や異物が底部に沈澱し、それが排水口４３，４３より汚水排水管４２に流れ込み、汚水排水管４２を通して汚水処理設備に流下するようになっている。 The separation means 41 includes a sewage drain pipe 42 communicated with the sewage treatment facility, and drainage ports 43, 43 communicating the sewage drain pipe 42 with the bottoms of the front chamber 32 and the rear chamber 33. 33, mud and foreign matter having a specific gravity higher than the water contained in the wastewater stored in 33, settles on the bottom, and flows into the sewage drain pipe 42 through the drain ports 43, 43, and flows down to the sewage treatment facility through the sewage drain pipe 42. It is supposed to be.
一方、水よりも比重の軽い油等は、遮壁３９，４０の上流側で分離されて水面に浮き上がり、それを管理用孔３６，３６より除去するようになっている。 On the other hand, oil having a specific gravity lower than that of water is separated on the upstream side of the shielding walls 39 and 40 and floats on the water surface, and is removed from the management holes 36 and 36.
そして、流出水用排水管１６は、上述の実施例と同様に、その下流側が貯留浸透槽１５に接続され、下流側排水管１４は、その下流側が汚水処理設備に接続されている。 The effluent drainage pipe 16 is connected to the storage and permeation tank 15 on the downstream side, and the downstream side drainage pipe 14 is connected to the sewage treatment facility, as in the above-described embodiment.
この排水処理設備では、排水が雨樋１１等から流入管１２を通って集水桝３０内に到達し、所定の水量以下では、連結管１３を通して下流側排出管１４に通され、下流側に流下させる。そして、下流側に設置された汚水処理設備で分離処理されて、処理済の水が河川や放水池等に放流される。 In this wastewater treatment facility, wastewater reaches from the rain gutter 11 or the like through the inflow pipe 12 into the catchment gutter 30, and below a predetermined amount of water, is passed through the connecting pipe 13 to the downstream discharge pipe 14, and to the downstream side. Let it flow down. And it isolate | separates by the sewage treatment equipment installed in the downstream, and the treated water is discharged to a river, a drainage pond, etc.
一方、連結管１３内が一定水量以上になると、管内の水位が流出孔２３，２３…の位置まで達し、一定水量以上に達した分の排水が連結管１３を流下する際に流出孔２３より集水桝３０、即ち前室３２内に流出する。 On the other hand, when the inside of the connecting pipe 13 exceeds a certain amount of water, the water level in the pipe reaches the position of the outflow holes 23, 23... It flows out into the water collecting tank 30, that is, the front chamber 32.
流出水ｗ１は、前室３２内に貯留され、所定の水位を超えると、越流孔３７より後室３３側に流出するようになっている。 The effluent water w <b> 1 is stored in the front chamber 32, and flows out from the overflow hole 37 toward the rear chamber 33 when it exceeds a predetermined water level.
このとき、水よりも比重の重い泥や異物は前室３２内で沈澱し、汚水配水管４２より汚水処理設備に流下するようになっており、水よりも比重の軽い油分等は、水と分離して水面上に浮き、それを管理用孔３６より除去するようになっている。 At this time, mud and foreign matter having a specific gravity greater than that of water settles in the front chamber 32 and flows down from the sewage distribution pipe 42 to the sewage treatment facility. It separates and floats on the water surface and is removed from the management hole 36.
次に、後室３３内に越流した排水は、後室３３内に貯留され、一定水位以上、即ち流出水用排水管１６のが接続された高さより水位が高くなると、流出水が流出水用排水管１６より貯留浸透槽１５に流下される。 Next, the waste water that overflowed into the rear chamber 33 is stored in the rear chamber 33, and when the water level becomes higher than a certain level, that is, the height at which the drain pipe 16 for the effluent water is connected, the effluent becomes the effluent water. The water is discharged from the drainage pipe 16 to the storage and penetration tank 15.
このとき、水よりも比重の重い泥や異物は後室３３内で沈澱し、汚水配水管４２より汚水処理設備に流下するようになっており、水よりも比重の軽い油分等は、水と分離して水面上に浮き、それを管理用孔３６より除去するようになっている。 At this time, mud or foreign matter having a specific gravity higher than that of water is precipitated in the rear chamber 33 and flows down from the sewage distribution pipe 42 to the sewage treatment facility. It separates and floats on the water surface and is removed from the management hole 36.
このように前室３２及び後室３３を通過する過程において、流出水ｗ１に含有された塵、異物及び油分等が除去されて流出水ｗ１は濾過された状態となり、これを貯留浸透槽１５において地中に浸透させる。 Thus, in the process of passing through the front chamber 32 and the rear chamber 33, the dust, foreign matter, oil, and the like contained in the effluent water w1 are removed, and the effluent water w1 is filtered, and this is stored in the storage permeation tank 15. Infiltrate into the ground.
尚、上述の実施例では、流出水用排水管の下流側に貯留浸透槽を設けた例について説明したが、流出水用排水管の下流側を放水池や河川とし、最終的にそこに濾過された流出水を放流するようにしてもよい。 In the above-described embodiment, an example in which a storage permeation tank is provided on the downstream side of the effluent drainage pipe has been described. However, the downstream side of the effluent drainage pipe is a drainage basin or river, and finally filtered there. The discharged effluent may be discharged.
また、上述の実施例では、集水部を集水桝とした例について説明したが、集水部を貯留浸透槽や放水（貯留）池等により構成してもよい。 Moreover, although the above-mentioned Example demonstrated the example which used the water collection part as the water catchment, you may comprise a water collection part by a storage permeation tank, a water discharge (storage) pond, etc.
更に、上述の実施例では、下流側排水管の下流側に汚水処理設備を備えた例について説明したが、環境に応じて汚水物質の含有率が低い場合には、河川や放水池等に接続し、放水するようにしてもよい。 Furthermore, in the above-described embodiment, an example in which a sewage treatment facility is provided on the downstream side of the downstream drain pipe has been described. However, when the content of sewage substances is low depending on the environment, it is connected to a river or a drainage pond. However, the water may be discharged.
また、連結管が多数の流出孔を備えた例について説明したが、連結管の上部に大きな流出孔を一つだけ形成するようにしてもよく、流出孔をメッシュ材等の透水性部材によって覆い、フィルターを設けるようにしてもよい。 In addition, although the example in which the connecting pipe is provided with a large number of outflow holes has been described, only one large outflow hole may be formed in the upper part of the connecting pipe, and the outflow hole is covered with a water permeable member such as a mesh material. A filter may be provided.
上述の実施例では、流入管、連結管及び下流側排水管をそれぞれ別個の管体をもって構成した例について説明したが、流入管、連結管及び下流側排水管を一本の管体をもって一体に構成し、その管体の集水部を通る部分に流出孔を形成するようにしてもよい。 In the above-described embodiment, the example in which the inflow pipe, the connection pipe, and the downstream drainage pipe are configured with separate pipes has been described. However, the inflow pipe, the connection pipe, and the downstream drainage pipe are integrated with a single pipe. It is also possible to form an outflow hole in a portion that passes through the water collecting portion of the tube.
