Description

本発明は、植物、魚貝、昆虫等が共存する水辺環境を創出するための水路を有する屋上緑化用人工地盤に関する。   The present invention relates to an artificial ground for rooftop greening having a water channel for creating a waterside environment where plants, fish shellfish, insects and the like coexist.

近年、ヒートアイランド現象の抑制、都市景観の向上等を目的として屋上緑化が行われている。特に、東京都が条例により一定基準を超える敷地面積を有する新たな建築物について屋上緑化を義務付けたことにより、屋上緑化の需要はより一層高くなっている。屋上緑化には、植物、魚貝、昆虫等が共存する空間を作るために水路を設けて水辺環境を創出するものがある。植物、魚貝、昆虫等の生物が共存する空間は、ビオトープと呼ばれ、人々に安らぎの場又は生物との触れあいの場を提供する。   In recent years, rooftop greening has been carried out for the purpose of suppressing the heat island phenomenon and improving the cityscape. In particular, the demand for rooftop greening has become even higher due to the Tokyo Metropolitan Government requiring rooftop greening for new buildings that have site areas exceeding a certain standard. Some rooftop greening creates a waterfront environment by providing waterways to create a space where plants, fish shellfish, insects, etc. coexist. A space where organisms such as plants, fish shells, and insects coexist is called a biotope, and provides a place of peace or contact with people.

従来の屋上緑化用人工地盤には、屋上に配置された水溜めと、該水溜め内に配置された透水層と、該透水層上にある植生層とを含むものがある（特許文献１、２参照）。
特開２００３−１０２２６５号公報 特開２００４−１２１１７８号公報 The conventional artificial ground for rooftop greening includes a water reservoir disposed on the rooftop, a water permeable layer disposed in the water reservoir, and a vegetation layer on the water permeable layer (Patent Document 1, 2).
JP 2003-102265 A JP 2004-121178 A

また、従来の他の屋上緑化用人工地盤は、屋上に配置された水溜めと、該水溜めを満たす透水層と、該透水層上にある植生層とを含み、該植生層は土からなり、前記植生層の上面に水路が形成されている（特願２００６−５４６１１）。前記植生層の前記上面は、該上面から前記屋上までの距離が前記植生層の一端部から他端部に向けて漸減するように傾斜しており、前記水路は前記一端部から前記他端部まで伸びる。   In addition, another conventional artificial ground for rooftop greening includes a water reservoir disposed on the roof, a water permeable layer that fills the water reservoir, and a vegetation layer on the water permeable layer, and the vegetation layer is made of soil. A water channel is formed on the upper surface of the vegetation layer (Japanese Patent Application No. 2006-54611). The upper surface of the vegetation layer is inclined so that a distance from the upper surface to the rooftop gradually decreases from one end portion to the other end portion of the vegetation layer, and the water channel extends from the one end portion to the other end portion. It extends to.

前記水路は、前記植生層の前記上面に前記水路をなす溝を設けることにより形成される。しかし、前記植生層に前記溝を設けることには多大な時間と労力とを要する。このため、前記水路の形成を効率的に行うことができない。   The water channel is formed by providing a groove forming the water channel on the upper surface of the vegetation layer. However, providing the groove in the vegetation layer requires a lot of time and labor. For this reason, the water channel cannot be formed efficiently.

本発明の目的は、水路を有する屋上緑化用人工地盤であって前記水路の形成をより効率的に行うことができる屋上緑化用人工地盤及びこれに用いる水路形成パネルを提供することである。   An object of the present invention is to provide an artificial ground for rooftop greening having a water channel and capable of forming the waterway more efficiently, and a water channel forming panel used therefor.

本発明は、それぞれが前記水路の一部をなす溝を有する複数の水路形成パネルを互いに隣接して配置することにより、効率的に前記水路を形成する。   The present invention efficiently forms the water channel by arranging a plurality of water channel forming panels each having a groove that forms a part of the water channel adjacent to each other.

本発明に係る、水路を有する屋上緑化用人工地盤は、互いに隣接して配置され、前記水路を形成する複数の水路形成パネルと、該複数の水路形成パネル上に配置された非透水性シートと、該非透水性シート上の植生層とを含む。各水路形成パネルは、前記水路の一部をなす溝を上面に有する板状の本体からなり、前記水路の上流側の水路形成パネルの前記本体の厚さは下流側の水路形成パネルの前記本体の厚さより厚い。   The artificial ground for rooftop greening having a water channel according to the present invention is disposed adjacent to each other, and a plurality of water channel forming panels forming the water channel, and a water-impermeable sheet disposed on the plurality of water channel forming panels, And a vegetation layer on the water-impermeable sheet. Each water channel forming panel is composed of a plate-shaped main body having a groove formed on the upper surface thereof, and the thickness of the main body of the water channel forming panel on the upstream side of the water channel is the main body of the water channel forming panel on the downstream side. Thicker than the thickness.

前記水路は、それぞれが前記水路の一部をなす溝を有する前記複数の水路形成パネルを互いに隣接して配置することにより形成する。これにより、従来の屋上緑化用人工地盤のように植生層に水路をなす溝を設けることなく水路を形成することができる。このため、水路の形成をより効率的に行うことができる。前記水路の上流側の水路形成パネルの前記本体の厚さが下流側の水路形成パネルの前記本体の厚さより厚いことから、前記水路の水は上流側の水路形成パネルから下流側の水路形成パネルへ流れる。   The water channel is formed by arranging the plurality of water channel forming panels, each having a groove forming a part of the water channel, adjacent to each other. Thereby, a water channel can be formed, without providing the groove | channel which makes a water channel in a vegetation layer like the conventional artificial ground for rooftop greening. For this reason, a water channel can be formed more efficiently. Since the thickness of the main body of the upstream water channel forming panel of the water channel is larger than the thickness of the main body of the downstream water channel forming panel, the water of the water channel is downstream from the upstream water channel forming panel. To flow.

各水路形成パネルの前記溝底から前記本体の下面までの距離は前記溝の一端部から他端部まで一定であり、前記上流側の水路形成パネルの前記溝底は前記下流側の水路形成パネルの前記溝底より上方に位置する。   The distance from the groove bottom of each water channel forming panel to the lower surface of the main body is constant from one end to the other end of the groove, and the groove bottom of the upstream water channel forming panel is the downstream water channel forming panel. Located above the bottom of the groove.

前記植生層は土からなり、前記植生層で植物を生育させる。前記非透水性シートは、前記植生層に供給された水が屋上へ漏れるのを防止する。   The vegetation layer is made of soil, and plants are grown on the vegetation layer. The water-impermeable sheet prevents water supplied to the vegetation layer from leaking to the rooftop.

前記屋上緑化用人工地盤は、前記非透水性シートと前記植生層との間に透水層を備える。前記植生層に供給された水は前記透水層を経て前記植生層から排出される。前記透水層は多孔質材料からなる。   The artificial green ground for rooftop greening includes a water permeable layer between the water impermeable sheet and the vegetation layer. The water supplied to the vegetation layer is discharged from the vegetation layer through the water permeable layer. The water permeable layer is made of a porous material.

前記屋上緑化用人工地盤は、前記水路内に配置された濾過層を備える。前記濾過層は前記水路の水を濾過する。前記濾過層は多孔質材料からなる。   The artificial green ground for rooftop greening includes a filtration layer disposed in the water channel. The filtration layer filters the water in the water channel. The filtration layer is made of a porous material.

本発明に係る、水路を有する屋上緑化用人工地盤に用いる水路形成パネルは、前記水路の一部をなす溝を上面に有する板状の本体からなる。前記溝の少なくとも一方の端部は前記本体の端部で開放されている。前記水路形成パネルは、前記水路を形成するように少なくとも１つの他の水路形成パネルに隣接して配置される。   The water channel formation panel used for the artificial ground for rooftop greening which has a water channel based on this invention consists of a plate-shaped main body which has the groove | channel which makes a part of the water channel in the upper surface. At least one end of the groove is open at the end of the body. The water channel forming panel is disposed adjacent to at least one other water channel forming panel so as to form the water channel.

前記溝底から前記本体の下面までの距離は前記溝の一端部から他端部まで一定である。前記本体は発泡スチロールからなる。これにより前記屋上緑化用人工地盤の軽量化を図ることができる。また、発泡スチロールが外部の熱を遮断するため、前記屋上緑化用人工地盤が設けられた建物内での冷暖房の使用を抑制することができる。   The distance from the groove bottom to the lower surface of the main body is constant from one end to the other end of the groove. The main body is made of expanded polystyrene. Thereby, the weight reduction of the artificial ground for rooftop greening can be achieved. Moreover, since the polystyrene foam blocks external heat, it is possible to suppress the use of air conditioning in the building provided with the artificial green ground for rooftop greening.

本発明によれば、水路を形成する複数の水路形成パネルであってそれぞれが前記水路の一部をなす溝を有する複数の水路形成パネルを互いに隣接して配置することにより、効率的に前記水路を形成することができる。これにより、屋上緑化用人工地盤のより効率的な施工を可能にする。   According to the present invention, a plurality of water channel forming panels that form a water channel, each having a groove that forms a part of the water channel, are arranged adjacent to each other, thereby efficiently providing the water channel. Can be formed. This allows more efficient construction of the artificial ground for rooftop greening.

図１に示すように、水路１０を有する屋上緑化用人工地盤１２は、屋上１４に互いに隣接して配置され、水路１０を形成する複数の水路形成パネル１６と、該複数の水路形成パネル上に配置された非透水性シート１８と、該非透水性シート上の植生層２０とを含む。図示の例では、屋上緑化用人工地盤１２は側壁２２で囲まれている。   As shown in FIG. 1, the rooftop greening artificial ground 12 having a water channel 10 is arranged adjacent to the roof 14 and includes a plurality of water channel forming panels 16 that form the water channel 10, and the plurality of water channel forming panels. The water-impermeable sheet 18 arrange | positioned and the vegetation layer 20 on this water-impermeable sheet are included. In the illustrated example, the artificial ground 12 for greening the roof is surrounded by side walls 22.

各水路形成パネル１６は、水路１０の一部をなす溝２４を上面２６に有する板状の本体２８からなる。本体２８の上面２６は水平である。複数の水路形成パネル１６の本体２８は互いに異なる厚さを有し、水路１０の上流側の水路形成パネル１６の本体２８の厚さは水路１０の下流側の水路形成パネル１６の本体２８の厚さより厚い。このため、水路１０の水は上流側の水路形成パネル１６から下流側の水路形成パネル１６へ流れる。   Each water channel forming panel 16 includes a plate-shaped main body 28 having a groove 24 forming a part of the water channel 10 on the upper surface 26. The upper surface 26 of the main body 28 is horizontal. The main bodies 28 of the plurality of water channel forming panels 16 have different thicknesses, and the thickness of the main body 28 of the water channel forming panel 16 on the upstream side of the water channel 10 is the thickness of the main body 28 of the water channel forming panel 16 on the downstream side of the water channel 10. Thicker than that. For this reason, the water in the water channel 10 flows from the upstream water channel forming panel 16 to the downstream water channel forming panel 16.

図示の例では、水路１０は４つの水路形成パネル１６により形成されている。各水路形成パネル１６において、本体２８は相対する一端部３０及び他端部３２を有し、溝２４は本体２８の一端部３０から他端部３２に向けて伸びる。   In the illustrated example, the water channel 10 is formed by four water channel forming panels 16. In each water channel forming panel 16, the main body 28 has one end 30 and the other end 32 that face each other, and the groove 24 extends from the one end 30 of the main body 28 toward the other end 32.

４つの水路形成パネル１６のうち上流側の３つの水路形成パネル１６のそれぞれにおいて、溝２４の一端部３４は本体２８の一端部３０で開放され、また溝２４の他端部３６は本体２８の他端部３２で開放されている。４つの水路形成パネル１６のうち最も下流側に位置する水路形成パネル１６において、溝２４の一端部３４は本体２８の一端部３０で開放され、また溝２４の他端部３６は本体２８の端部で開放されていない。４つの水路形成パネル１６のそれぞれの溝２４底から本体２８の下面３８までの距離は溝２４の一端部３４から他端部３６まで一定であり、隣接する２つの水路形成パネル１６のうち上流側の水路形成パネル１６の溝２４底は下流側の水路形成パネル１６の溝２４底より上方に位置する。   In each of the upstream three water channel forming panels 16 among the four water channel forming panels 16, one end 34 of the groove 24 is opened at one end 30 of the main body 28, and the other end 36 of the groove 24 is formed in the main body 28. Opened at the other end 32. In the water channel forming panel 16 located on the most downstream side of the four water channel forming panels 16, one end 34 of the groove 24 is opened at one end 30 of the main body 28, and the other end 36 of the groove 24 is the end of the main body 28. Not open in the department. The distance from the bottom of each groove 24 of the four water channel forming panels 16 to the lower surface 38 of the main body 28 is constant from one end 34 to the other end 36 of the groove 24, and the upstream side of the two adjacent water channel forming panels 16. The bottom of the groove 24 of the water channel forming panel 16 is located above the bottom of the groove 24 of the downstream water channel forming panel 16.

水路１０は、川部１０ａと、該川部の下流側の端部で川部１０ａと連通する池部１０ｂとからなる。上流側の３つの水路形成パネル１６のそれぞれの溝２４は川部１０ａの一部をなす。最も下流側に位置する水路形成パネル１６の溝２４は川部１０ａの一部と池部１０ｂとをなす。水路１０の平面形状はほぼ直線状である。   The water channel 10 includes a river part 10a and a pond part 10b that communicates with the river part 10a at the downstream end of the river part. Each groove 24 of the upstream three water channel forming panels 16 forms part of the river part 10a. The groove 24 of the water channel forming panel 16 located on the most downstream side forms part of the river part 10a and the pond part 10b. The planar shape of the water channel 10 is substantially linear.

本体２８は、溝２４底から本体２８の下面３８までの距離が溝２４の一端部３４から他端部３６まで一定である図示の例に代え、溝２４底から本体２８の下面３８までの距離が溝２４の一端部３４から他端部３６に向けて漸減するものであってもよい。この場合、上流側の水路形成パネル１６の溝２４の他端部３６における溝２４底は下流側の水路形成パネル１６の溝２４の一端部３４における溝２４底と連続している。   In the main body 28, the distance from the bottom of the groove 24 to the lower surface 38 of the main body 28 is constant from the one end 34 to the other end 36 of the groove 24. May gradually decrease from one end 34 of the groove 24 toward the other end 36. In this case, the bottom of the groove 24 at the other end 36 of the groove 24 of the upstream water channel forming panel 16 is continuous with the bottom of the groove 24 at one end 34 of the groove 24 of the downstream water channel forming panel 16.

本体２８は発泡スチロールからなる。これにより屋上緑化用人工地盤１２の軽量化を図ることができ、屋上１４に作用する積載荷重を低減することができる。また、発泡スチロールが外部の熱を遮断するため、屋上緑化用人工地盤１２が設けられた建物内での冷暖房の使用を抑制することができる。さらに、再生した発泡スチロールで本体２８を作ることにより資源の有効利用を図ることができる。   The main body 28 is made of expanded polystyrene. Thereby, weight reduction of the artificial ground 12 for rooftop greening can be achieved, and the loading load which acts on the rooftop 14 can be reduced. Moreover, since a polystyrene foam cuts off external heat, use of the air conditioning in the building in which the artificial ground 12 for rooftop greening was provided can be suppressed. Furthermore, the resources can be effectively used by making the main body 28 from the regenerated expanded polystyrene.

本体２８を製作するとき、まず、予め定められた本体２８の厚さより厚い発泡スチロールの板状体を用意し、該板状体の上面に溝２４を成形する。溝２４の成形は、前記板状体の上面を溝状に切り取ることによるものでもよいし、発泡スチロールの成型によるものでもよい。その後、前記板状体の厚さが予め定められた本体２８の厚さと等しくなるように前記板状体の下部を切断する。これにより、任意の厚さを有する本体２８を比較的容易に作ることができ、屋上緑化用人工地盤１２をより効率的に施工することができる。本体２８の製作は、予め定められた本体２８の厚さより薄い発泡スチロールの板状体に溝２４を成形し、全体の厚さが、予め定められた本体２８の厚さと等しくなるように前記板状体の下面に他の発泡スチロールの板状体を重ね合わせることによるものでもよい。また、本体２８の製作は、予め定められた本体２８の厚さと同じ厚さを有する発泡スチロールの板状体に溝２４を成形することによるものでもよい。本体２８は、発泡スチロールからなる上記の例に代え、軽石の成型品でもよい。   When the main body 28 is manufactured, first, a styrofoam plate-like body thicker than a predetermined thickness of the main body 28 is prepared, and the grooves 24 are formed on the upper surface of the plate-like body. The groove 24 may be formed by cutting the upper surface of the plate-like body into a groove shape or by molding a polystyrene foam. Thereafter, the lower portion of the plate-like body is cut so that the thickness of the plate-like body becomes equal to a predetermined thickness of the main body 28. Thereby, the main body 28 which has arbitrary thickness can be made comparatively easily, and the artificial ground 12 for rooftop greening can be constructed more efficiently. The main body 28 is manufactured by forming the groove 24 in a polystyrene foam plate that is thinner than a predetermined thickness of the main body 28, so that the overall thickness is equal to the predetermined thickness of the main body 28. It is also possible to superimpose another expanded polystyrene plate on the lower surface of the body. The production of the main body 28 may be performed by forming the groove 24 in a sheet of polystyrene foam having the same thickness as the predetermined thickness of the main body 28. The main body 28 may be a molded product of pumice instead of the above example made of polystyrene foam.

水路形成パネル１６の本体２８の寸法は、例えば、幅が約１０００ｍｍ、長さが約２０００ｍｍ、高さが約１００ｍｍないし約８００ｍｍである。上流側の水路形成パネル１６の本体２８と下流側の水路形成パネル１６の本体２８とは、接着剤、特開２００５−１６０３６号公報に記載された緊結具等により結合されている。   The dimensions of the main body 28 of the water channel forming panel 16 are, for example, a width of about 1000 mm, a length of about 2000 mm, and a height of about 100 mm to about 800 mm. The main body 28 of the upstream water channel forming panel 16 and the main body 28 of the downstream water channel forming panel 16 are joined together by an adhesive, a fastener described in JP-A-2005-16036, or the like.

植生層２０で植物を生育させる。植生層２０の上面４４は、該上面から屋上１４までの距離が上流側から下流側に向けて漸減するように傾斜している。植生層２０は土からなる。前記土は、屋上１４に作用する積載荷重を低減するために人工軽量土壌であることが望ましい。植生層２０には散水、降雨等により植物の生育に必要な水が供給される。非透水性シート１８は、植生層２０に供給された水が屋上１４へ漏れるのを防止する。   Plants are grown in the vegetation layer 20. The upper surface 44 of the vegetation layer 20 is inclined so that the distance from the upper surface to the roof 14 gradually decreases from the upstream side toward the downstream side. The vegetation layer 20 is made of soil. The soil is preferably an artificial lightweight soil in order to reduce the load load acting on the roof 14. The vegetation layer 20 is supplied with water necessary for plant growth by watering, raining, or the like. The water-impermeable sheet 18 prevents water supplied to the vegetation layer 20 from leaking to the roof 14.

図示の例では、屋上緑化用人工地盤１２は、非透水性シート１８と植生層２０との間に透水層４０を備える。植生層２０に供給された水は透水層４０を経て植生層２０から排出される。これにより、植生層２０の余分な水を効率よく排出することができ、植生層２０で生育する植物の根腐れを防止することができる。透水層４０は、パーライト、発泡ガラス等の多孔質材料からなる。   In the illustrated example, the rooftop greening artificial ground 12 includes a water-permeable layer 40 between the water-impermeable sheet 18 and the vegetation layer 20. The water supplied to the vegetation layer 20 is discharged from the vegetation layer 20 through the water permeable layer 40. Thereby, the excess water of the vegetation layer 20 can be discharged | emitted efficiently, and the root rot of the plant growing in the vegetation layer 20 can be prevented. The water permeable layer 40 is made of a porous material such as pearlite or foamed glass.

屋上緑化用人工地盤１２は、水路１０内に配置された濾過層４２を備える。濾過層４２は水路１０の水を濾過して浄化する。水路１０の水を浄化することは、植物、魚貝、昆虫等の成育、特にホタルの成育にとって重要である。濾過層４２は、発泡ガラス、多孔質セラミックス、発泡金属、発泡ウレタン、軽石、ゼオライト等のような多孔質材料からなるのが望ましい。多孔質材料は、内部に無数の微細な孔を有するため、水質汚濁の原因となる有機物又は窒素、リン等の栄養塩類を効率よく吸着する。また、前記微細な孔には微生物が付着しやすいため、該微生物の働きによって水を浄化することもできる。   The rooftop greening artificial ground 12 includes a filtration layer 42 disposed in the water channel 10. The filtration layer 42 filters and purifies the water in the water channel 10. Purifying the water in the water channel 10 is important for the growth of plants, fish shells, insects, etc., especially for the growth of fireflies. The filtration layer 42 is preferably made of a porous material such as foam glass, porous ceramics, foam metal, foam urethane, pumice, zeolite, or the like. Since the porous material has innumerable fine pores therein, it efficiently adsorbs organic substances that cause water pollution or nutrients such as nitrogen and phosphorus. Further, since microorganisms are likely to adhere to the fine pores, water can be purified by the action of the microorganisms.

屋上緑化用人工地盤１２は、水路１０の下流部、すなわち池部１０ｂの水を水路１０の上流部、すなわち川部１０ａの上流側の端部１０ｃへ送る配管４６を備える。池部１０ｂと連通する水槽（図示せず）に池部１０ｂの水を汲み上げるポンプ（図示せず）が配置されており、配管４６は、一端部が前記ポンプに接続され、また他端部が川部１０ａの上流側の端部１０ｃに接続されている。前記ポンプを運転することにより、水路１０の水を循環させることができる。   The artificial green ground 12 for rooftop greening includes a pipe 46 that sends the water in the downstream portion of the water channel 10, that is, the pond portion 10b, to the upstream portion of the water channel 10, that is, the upstream end portion 10c of the river portion 10a. A pump (not shown) for pumping the water of the pond part 10b is disposed in a water tank (not shown) communicating with the pond part 10b, and one end of the pipe 46 is connected to the pump, and the other end is a river part. 10a is connected to the upstream end 10c. By operating the pump, the water in the water channel 10 can be circulated.

屋上緑化用人工地盤１２を施工するとき、まず、水路１０を形成するように屋上１４に複数の水路形成パネル１６を互いに隣接して配置する。次に、複数の水路形成パネル１６上に非透水性シート１８を配置する。その後、非透水性シート１８上に透水層４０を設け、透水層４０上に植生層２０を設ける。   When constructing the artificial ground 12 for greening the roof, first, a plurality of water channel forming panels 16 are arranged adjacent to each other on the roof 14 so as to form the water channel 10. Next, the water-impermeable sheet 18 is disposed on the plurality of water channel forming panels 16. Thereafter, the water permeable layer 40 is provided on the water-impermeable sheet 18, and the vegetation layer 20 is provided on the water permeable layer 40.

このように、水路１０の形成は、それぞれに水路１０の一部をなす溝２４が予め設けられた複数の水路形成パネル１６を互いに隣接して配置することにより行う。よって、従来の屋上緑化用人工地盤と違い、水路をなす溝を植生層に設ける必要がない。このため、水路の形成をより効率的に行うことができる。   In this manner, the water channel 10 is formed by arranging a plurality of water channel forming panels 16 each having a groove 24 that forms a part of the water channel 10 in advance adjacent to each other. Therefore, unlike the conventional artificial ground for rooftop greening, it is not necessary to provide the vegetation layer with a groove that forms a water channel. For this reason, a water channel can be formed more efficiently.

また、上流側の水路形成パネル１６の本体２８の厚さが下流側の水路形成パネル１６の本体２８の厚さより厚いため、植生層２０を設けるとき、各水路形成パネル１６上の植生層２０の厚さを変化させる必要がない。このため、比較的容易に植生層２０を設けることができる。   Further, since the thickness of the main body 28 of the upstream water channel forming panel 16 is larger than the thickness of the main body 28 of the downstream water channel forming panel 16, when the vegetation layer 20 is provided, the vegetation layer 20 on each water channel forming panel 16 is There is no need to change the thickness. For this reason, the vegetation layer 20 can be provided comparatively easily.

図２に示す例では、各水路形成パネル１６の溝２４底から本体２８の下面３８までの距離は、溝２４の一端部３４から他端部３６まで一定である図１に示した例に代え、溝２４の一端部３４から他端部３６に向けて漸増し、次いで漸減する。各水路形成パネル１６の溝２４の一端部３４の溝２４底は他端部３６の溝２４底より上方に位置し、上流側の水路形成パネル１６の溝２４の他端部３６における溝２４底は下流側の水路形成パネル１６の溝２４の一端部３４における溝２４底と連続している。   In the example shown in FIG. 2, the distance from the bottom of the groove 24 of each water channel forming panel 16 to the lower surface 38 of the main body 28 is constant from one end 34 to the other end 36 of the groove 24 instead of the example shown in FIG. 1. The groove 24 gradually increases from one end 34 to the other end 36 and then gradually decreases. The bottom of the groove 24 at one end 34 of the groove 24 of each water channel forming panel 16 is located above the bottom of the groove 24 at the other end 36, and the bottom of the groove 24 at the other end 36 of the groove 24 of the upstream water channel forming panel 16. Is continuous with the bottom of the groove 24 at one end 34 of the groove 24 of the downstream water channel forming panel 16.

溝２４底から本体２８の下面３８までの距離が溝２４の一端部３４から他端部３６に向けて漸増し、次いで漸減するため、水路１０の深さは、溝２４の一端部３４側で比較的浅く、溝２４の他端部３６側で比較的深い。このため、水路１０の水の流速は、溝２４の一端部３４側で比較的速くなり、他端部３６側で比較的遅くなる。   Since the distance from the bottom of the groove 24 to the lower surface 38 of the main body 28 gradually increases from one end 34 to the other end 36 of the groove 24 and then gradually decreases, the depth of the water channel 10 is increased at the one end 34 side of the groove 24. It is relatively shallow and relatively deep on the other end 36 side of the groove 24. For this reason, the flow rate of water in the water channel 10 is relatively fast on the one end 34 side of the groove 24 and relatively slow on the other end 36 side.

ところで、屋上緑化用人工地盤１２にホタルを生息させるためには、ホタルの幼虫の餌となるカワニナを水路１０に生息させることが重要である。カワニナは水の流れの速い場所を好む。溝２４の一端部３４側で水路１０の水の流速が比較的速くなることにより、水路１０にカワニナの生息に適した環境を創ることができる。   By the way, in order for fireflies to inhabit the artificial ground 12 for greening the roof, it is important to inhabit the water channel 10, which is a food for the firefly larvae. Kawanina prefers a place with fast water flow. Since the flow rate of water in the water channel 10 becomes relatively fast on the one end 34 side of the groove 24, it is possible to create an environment suitable for the habitat of river bream in the water channel 10.

図３に示す例では、上流側の３つの水路形成パネル１６のそれぞれにおいて、本体２８の上面２６は、水平である図１に示した例に代え、本体２８の一端部３０から他端部３２に向けて本体２８の厚さが漸増するように傾斜している。上流側の水路形成パネル１６の本体２８の他端部３２は下流側の水路形成パネル１６の本体２８の一端部３０に隣接しており、上流側の水路形成パネル１６の本体２８の一端部３０の厚さは下流側の水路形成パネル１６の本体２８の一端部３０の厚さより厚い。   In the example illustrated in FIG. 3, in each of the upstream three water channel forming panels 16, the upper surface 26 of the main body 28 is horizontal, instead of the example illustrated in FIG. 1, the one end 30 to the other end 32 of the main body 28. The main body 28 is inclined so that the thickness gradually increases. The other end 32 of the main body 28 of the upstream water channel forming panel 16 is adjacent to one end 30 of the main body 28 of the downstream water channel forming panel 16, and one end 30 of the main body 28 of the upstream water channel forming panel 16. Is thicker than the thickness of one end 30 of the main body 28 of the downstream water channel forming panel 16.

ところで、図１に示したように各水路形成パネル１６の本体２８の上面２６が水平である場合、上流側の水路形成パネル１６の本体２８の厚さが下流側の水路形成パネル１６の本体２８の厚さより厚いため、植生層２０の土は、崩れ、低い方へ、すなわち水路１０の上流側から下流側に向けて移動する。これにより、上流側の水路形成パネル１６上で植生層２０の土が不足するという問題が生じる。本体２８の上面２６が、本体２８の一端部３０から他端部３２に向けて本体２８の厚さが漸増するように傾斜していることにより、植生層２０の土が水路１０の上流側から下流側へ移動するのを防止することができる。   By the way, as shown in FIG. 1, when the upper surface 26 of the main body 28 of each water channel forming panel 16 is horizontal, the thickness of the main body 28 of the upstream water channel forming panel 16 is equal to the main body 28 of the downstream water channel forming panel 16. Therefore, the soil of the vegetation layer 20 collapses and moves to the lower side, that is, from the upstream side to the downstream side of the water channel 10. Thereby, the problem that the soil of the vegetation layer 20 runs short on the upstream water channel formation panel 16 arises. The upper surface 26 of the main body 28 is inclined so that the thickness of the main body 28 gradually increases from one end 30 to the other end 32 of the main body 28, so that the soil of the vegetation layer 20 is removed from the upstream side of the water channel 10. It can prevent moving to the downstream side.

また、本体２８の一端部３０から他端部３２に向けて本体２８の厚さが漸増するように傾斜していることにより、散水、降雨等により植生層２０に供給された水が水路１０の上流側から下流側へ流れるのを妨げ、前記水を本体２８上に溜めることができる。これにより、植生層２０は、本体２８上に溜まった水を吸収して植物の生育に必要な水分を確保することができる。   Further, since the thickness of the main body 28 is inclined from the one end 30 to the other end 32 of the main body 28, the water supplied to the vegetation layer 20 by watering, raining, etc. The water can be prevented from flowing from the upstream side to the downstream side, and the water can be stored on the main body 28. Thereby, the vegetation layer 20 can ensure the water | moisture content required for the growth of a plant by absorbing the water collected on the main body 28. FIG.

図４に示す例では、上流側の３つの水路形成パネル１６のそれぞれは、本体２８のみからなる図１ないし３に示した例に代え、本体２８と、該本体の他端部３２で上面２６から突出する土留め壁４８とを有する。上流側の水路形成パネル１６の本体２８の他端部３２は下流側の水路形成パネル１６の本体２８の一端部３０に隣接しており、上流側の水路形成パネル１６の本体２８の厚さは下流側の水路形成パネル１６の本体２８の厚さより厚い。土留め壁４８は、本体２０と一体で形成された突起からなる。土留め壁４８の断面形状は矩形であるが、これに代えて三角形、台形等でもよい。土留め壁４８は、突起からなる図示の例に代え、本体２０に取り付けられた部材からなるものでもよい。   In the example shown in FIG. 4, each of the upstream three water channel forming panels 16 is replaced with the main body 28 and the upper end 26 at the other end 32 of the main body instead of the example shown in FIGS. And a retaining wall 48 projecting therefrom. The other end 32 of the main body 28 of the upstream water channel forming panel 16 is adjacent to one end 30 of the main body 28 of the downstream water channel forming panel 16, and the thickness of the main body 28 of the upstream water channel forming panel 16 is It is thicker than the thickness of the main body 28 of the downstream channel forming panel 16. The earth retaining wall 48 includes a protrusion formed integrally with the main body 20. The cross-sectional shape of the earth retaining wall 48 is a rectangle, but it may be a triangle or a trapezoid instead. The earth retaining wall 48 may be formed of a member attached to the main body 20 instead of the illustrated example of the protrusion.

土留め壁４８は、植生層２０の土が水路１０の上流側から下流側へ移動するのを防止する。このため、上流側の水路形成パネル１６上で植生層２０の土が不足するという問題は生じない。また、土留め壁４８は、散水、降雨等により植生層２０に供給された水が水路１０の上流側から下流側へ流れるのを妨げる。これにより、前記水を本体２８上に溜めることができ、植生層２０は、本体２８上に溜まった水を吸収して植物の生育に必要な水分を確保することができる。   The earth retaining wall 48 prevents the soil of the vegetation layer 20 from moving from the upstream side to the downstream side of the water channel 10. For this reason, the problem that the soil of the vegetation layer 20 runs short on the upstream water channel formation panel 16 does not arise. In addition, the earth retaining wall 48 prevents water supplied to the vegetation layer 20 from watering, raining, or the like from flowing from the upstream side to the downstream side of the water channel 10. Thereby, the said water can be stored on the main body 28, and the vegetation layer 20 can absorb the water collected on the main body 28, and can ensure the water | moisture content required for growth of a plant.

In the first water channel forming panel 16a, the main body 28a has one end 30a and the other end 32a facing each other, one end 34a of the groove 24a is opened at one end 30a of the main body 28a, and the other end of the groove 24a. 36a is open | released by the other end part 32a of the main body 28a, and the planar shape of the groove | channel 24a is linear (FIG. 5). In the second water channel forming panel 16b, the main body 28b has adjacent one end 30b and the other end 32b, one end 34b of the groove 24b is opened at one end 30b of the main body 28b, and the other end of the groove 24b. 36b is open | released by the other end part 32b of the main body 28b, and the planar shape of the groove | channel 24b is curvilinear (FIG. 6). In the third water channel forming panel 16c, one end 34c of the groove 24c is opened at the end 30c of the main body 28c, and the other end 36c of the groove 24c is not opened at the end of the main body 28c. (FIG. 7).

One first water channel forming panel 16a, four second water channel forming panels 16b, and two third water channel forming panels 16c are arranged from the upstream side (upper right in the drawing) to the downstream side (lower left in the drawing) of the water channel 10.
