Description

【０００１】
【発明の属する技術分野】
本発明は、地下への透水を可能とし、且つ、ヘドロ・ゴミ等が堆積しない水路及び水路用ブロックに関する。
【０００２】
【従来の技術】
従来、水路底部より水を地面（地下）に染み込ませるには、図１６、図１７に示すように枡１０１等を設置していた。水路の要部には枡部が設けられており、枡部１０１の内部には、砂利１０２等が敷き詰められて砂利１０２等により外部と連通している。雨水が水路を流れた後は、水路底面部には雨水は存在しないが、要所に設けられた枡部１０１には雨水１０３が溜まっている状態となる。この枡部１０１に溜まった雨水は、砂利１０２等を浸透して、地下へ透水し、地下水の増量を図っている。
【０００３】
しかし、このような水路及び枡部は、雨水が透水した後に透水部である砂利１０２上に雨水に含まれていたヘドロ・ゴミ１０４等が堆積し、悪臭又はボーフラ等が発生する等の問題があった。
【０００４】
【発明が解決しようとする課題】
現在、降雨量が少ないことによる深刻な水不足が問題となっている地域がある。例えば、平成１４年の松山地方もその一つである。水路内の水をそのまま海に流出するのではなく、少しでも地下に透水させ、地下水の増量を図る必要がある。
【０００５】
また、従来の水路における透水部にはヘドロ・ゴミ等が堆積し、悪臭の原因又はボーフラ等が発生する原因となっている。これらのヘドロ・ゴミ等の影響を避けるため浸透用の枡を設けることを敬遠する地域もあった。
【０００６】
したがって、本発明は、ヘドロ・ゴミ等が堆積することなく、水路内の水を地下に透水させ、地下水の増量を可能とする水路及びこれに用いる水路用ブロックの提供を目的とするものである。
【０００７】
【課題を解決するための手段】
上述したような目的を達成するために提案される本発明に係る水路用ブロックは、底面部と、上記底面部に相対向する側縁に設けられた一対の側壁とからなり、開口された流水方向に他の水路用ブロックと連結されて水路を形成し、上記底面部には、流水方向の上下に傾斜した傾斜面を有する集水部が設けられ、上記集水部には、上記集水部の下方に、上記傾斜面と段差を有しないように連続して上記集水部に貯留した水を外部に排出する排水部が設けられているものである。
【０００８】
この水路用ブロックに設けられた集水部は、雨等の流水が流れた後も、一定期間は流水を保有することができ、集水部の下部に設けられる排水部から地下に流水を排出させることができる。換言すれば、地面に流水を供給することができ、地下水の増量を図ることができる。また、この集水部は、底面部に設けられた傾斜面により形成されており、雨等により、ある程度の流量がある時に、排水部に堆積したゴミ・ヘドロ等を流動させ、取り除くことができる。
【０００９】
また、本発明に係る水路用ブロックの集水部に設けられた傾斜面は、排水部との間に段部が形成されないように構成しているため、水路内を流れる流水により、排水部に堆積したゴミ・ヘドロ等を容易に取り除くことができる。
【００１０】
また、本発明に係る水路用ブロックを用いた水路は、底面部と、上記底面部に相対向する側縁に設けられた一対の側壁とからなる水路用ブロックを開口された流水方向に連結して形成され、上記底面部には、流水方向の上下に傾斜した傾斜面を有する集水部が設けられ、上記集水部には、上記集水部の下方に、上記傾斜面と段差を有しないように連続して上記集水部に貯留した水を外部に排出する排水部が設けられ、上記水路用ブロックの下側に、上記排水部から排出した水を透水する透水部が設けられているものである。本発明に係る水路用ブロックを用いた水路は、ゴミ・ヘドロ等が堆積することなく、地下に水を供給できるので、地下水を増量させることができる。
【００１１】
【発明の実施の形態】
以下、本発明に係る水路及びこれに用いる水路用ブロックの具体的な実施の形態について、図面を参照しながら説明する。
【００１２】
本発明に係る水路に用いる水路用ブロックは、図１に示すように、底面部１３と、この底面部１３の相対向する側縁に設けられた一対の側壁１１、１２とから構成される。
【００１３】
この一対の側壁１１、１２と底面部１３は、流水方向に垂直な平面状に略Ｕ字状の断面形状を有しており、この内部に雨水等の流水を流す水路を形成する。
【００１４】
底面部１３には、流水方向の上下に傾斜した傾斜面１４、１５を有する集水部１６が設けられている。傾斜面１４、１５は、流水方向の互いに異なる方向に上下に傾斜しており、この傾斜面１４、１５により囲まれた部分は流水し、流水が終了した時に、流体を集水して、所定量溜めることができる集水部１６を形成する。尚、本実施例では、図１に示すように、傾斜面１４、１５は、連続的に滑らかに形成された曲線状であるが、直線状に傾斜したものでも良い。
【００１５】
この集水部１６には、集水部１６の下方の一番低い部分に、集水部１６に溜めた水を外部、すなわち地面（土）に排出する排水部１７が設けられている。この排水部１７は、例えば、図１に示すように傾斜面１４、１５の下端に設けた開口部１８である。
【００１６】
図２に示すように、開口部１８には、底面部１３の開口端における段差をなくすように砂利等からなる透水材１９を配設する。この開口端に配設された透水材１９により、排水部１７（開口部１８）と傾斜面１４、１５は、段差を有しない滑らかな面を形成している。本実施例では、透水材１９として、砂利を敷設しているが、砕石等の流水に流されることなく、且つ透水性を有するものであれば良い。
【００１７】
本発明に係る水路は、上述の水路用ブロックの下側に、上記排水部１７から排出した水を透水する透水部２２が設けられている。この透水部２２には、砂利、砂、モルタル、砕石等からなる透水部材が配設されている。
【００１８】
この水路に、雨等の流水が流れ込んだ時、水路は図３に示すような状態となる。さらに、この流水の流入が終わった時、水路は図４に示すような状態となる。図中矢印Ａは、流水の流れ方向を示すものである。図４に示すように、傾斜面１４、１５により囲まれた集水部１６には、集水された流水２０を所定量溜めることができる。このとき、傾斜面１４、１５の高低差、傾斜量を変更することにより、この流水を保有できる量を調整することが可能である。集水部１６に保有された流水２０は、排水部１７から外部、すなわち、水路の下の地面に排出される。このとき、本実施例では、開口部１８（排水部１７）に設けられた透水材１９を透水して排出される。
【００１９】
図５に示すように、集水部１６に保有された流水が排水部１７を透水して外部に排出された後、排水部１７には、流水２０中に含まれた堆積物２１が堆積する。この堆積物２１は、雨水等に含まれるゴミやヘドロ等である。また、図７は、集水部１６に保有された流水２０が透水され、堆積物２１が堆積している状態を示す図である。ここで、透水部に段差を有する段部が形成された場合は、堆積物は、その段部に堆積してしまう恐れがある。また、このゴミやヘドロ等の堆積物は、長期間堆積することで、悪臭の原因又はボーフラ等が発生する原因となる。ここで、排水部１７から外部に排出された流水は、水路用ブロックの下側に設けられた透水部２２を透水して、地下に流入する。
【００２０】
上述のように、排水部１７と傾斜面１４、１５は段差を有しない滑らかな面を形成しているため、この堆積物２１は、次に流水２０等が流入し、一定の流速となった時、図６に示すように、その流水２０の流れの勢いにより、排水部１７から流されて、取り除かれる。堆積物２１が除去された後は、図４に示すように、集水部１６に流体が保有された状態となる。このように、本願に係る水路用ブロック及びこれを用いた水路は、堆積物２１を堆積させることなく、排水部１７から流水２０を排出させることができるものである。すなわち、本願に係る水路用ブロック及びこれを用いた水路は、堆積物２１を堆積することなく、地面に水を供給し、地下水を増加させることを可能とするものである。
【００２１】
さらに、上述の実施例では、集水部が底面部の略中央に設けられているが、図８に示すように、集水部３６が底面部３３の流路方向の両端に設けられていても良い。この水路用ブロック３０の底面部３３には、流路方向に傾斜面３４、３５が設けられる。一の水路用ブロック３０の傾斜面３４と、この水路用ブロック３０に隣接する水路用ブロックの傾斜面により囲まれた部分が集水部３６となる。この集水部３６の下方の一番低い部分に、集水部３６に溜められた水を外部に排出する排水部として、例えば開口部３８が形成されている。図８に示すように、集水部３６が底面部３３の流路方向の両端に設けられた場合も、上述と同様の機能を有するので、堆積物が堆積することなく、地下に流水を排出可能である。また、上述の実施例において、傾斜面は２つ設けられているが、傾斜面は１つでも良い。
【００２２】
次に、本願の水路用ブロックの他の実施例について、図９、図１０を、用いて説明する。尚、上述の実施例と同様のものには、同じ符号を付して、説明を省略する。
【００２３】
本実施例に係る水路用ブロック４０は、集水部４６が底面部４３の一の対角線上を略頂部として下方に傾斜する２つの傾斜面４４、４５を有し、各傾斜面の下側に排水部４７が設けられている。
【００２４】
底面部４３の対角線の内一の対角線４９は、略頂部を形成し、この対角線４９の両側には、下方に向かって傾斜する傾斜面４４、４５が形成される。図１０に示すように、一の水路用ブロック４０の傾斜面４４と、該傾斜面に接するように配設された他の水路用ブロック４０ａの傾斜面の内、傾斜面４４に相対向する傾斜面４５ａとにより囲まれた領域は雨水等が流水した後に、流水を溜めることができる集水部４６を形成する。この集水部４６には、その一番低い部分に排水部４７が設けられる。この排水部４７は、集水部４６が保有した流水を、透水させ、地面（土）に排出させる。この排水部４７は、例えば、図９に示すように底面部４３の流水方向の両端に設けられた開口部４８である。
【００２５】
この開口部４８も、上述の実施例と同様に、砂利等の透水材１９が敷設されることにより、一の水路用ブロック４０の傾斜面４４、他の水路用ブロック４０ａの傾斜面４５ａ及び開口部４８は、段差のない滑らかな面を形成している。よって、本実施例に係る水路用ブロック４０及びこれを用いた水路は、堆積物が堆積することなく、地下に流水を排出可能とするものである。
【００２６】
また、本願の水路用ブロックのさらに他の実施例について、図１１、図１２を用いて説明する。尚、上述の実施例と同様のものには、同じ符号を付して、説明を省略する。
【００２７】
この水路用ブロック５０は、集水部６１が底面部５３の一対の対角線５８、５９の交点となる略中心を頂部として下方に傾斜する４つの傾斜面５４〜５７を有し、流水方向に相対向する傾斜面の下側に排水部６２を設ける。
【００２８】
底面部５３の一対の対角線５８、５９の交点は、最も厚みを有して形成される。換言すると、対角線５８、５９の交点は、頂部６０を形成し、対角線５８、５９に沿って四方に傾斜面５４〜５７を有している。
【００２９】
図１２に示すように、一の水路用ブロック５０の傾斜面５４と該傾斜面が隣接するように配設された他の水路用ブロック５０ａの傾斜面５５ａにより囲まれた領域は雨水等が流水した後に、流水を溜めることができる集水部６１を形成する。この集水部６１には、その一番低い部分に排水部６２が設けられる。この排水部６２は、集水部６１が保有した流水を、透水させ、地面（土）に排出させる、この排水部６２は、例えば図１１に示すように底面部５３の流路方向の両端に設けられた開口部６３である。
【００３０】
この開口部６３も、上述の実施例と同様に、砂利等の透水材１９が敷設されることにより、一の水路用ブロック５０の傾斜面５４、他の水路用ブロック５０ａの傾斜面５５ａ及び開口部６３は、段差のない滑らかな面を形成している。よって、本実施例に係る水路用ブロック５０及びこれを用いた水路は、堆積物が堆積することなく、地下に流水を排出可能とするものである。
【００３１】
また、本願の水路用ブロックのさらに他の実施例について、図１３〜図１５を用いて説明する。本実施例に係る水路用ブロック７０は、図１３に示すように、底面部７３と、この底面部１３の流水方向に相対向する側縁に設けられた一対の側壁７１、７２とから構成される。この一対の側壁７１、７２と底面部７３は、流水方向に垂直な平面上に略Ｕ字状の断面形状を有しており、この内部に雨水等の流水を流す水路を形成する。
【００３２】
底面部７３には、流水方向の上下に傾斜した傾斜面７４、７５と、流水方向と略直角方向に傾斜する傾斜面７６とを有する集水部７８が設けられている。傾斜面７４、７５は、流水方向の互いに異なる方向に上下に傾斜している。この傾斜面７４、７５と流水方向と略直角方向に傾斜する傾斜面７６により囲まれた部分は流水し、流水が終了した時に、流水を集水して、所定量溜めることができる集水部７８を形成する。この集水部７８には、集水部７８の下方の一番低い部分に、集水部７８に溜めた水を外部、すなわち地面（土）に排出する排水部７９が設けられている。
【００３３】
この排水部７９は、例えば、図１５に示すように、傾斜面７６の下側で接触する側壁７２との角部７７に形成されており、外部に連通する貫通孔８０である。この貫通孔８０には、集水部７８に保有した流水を、離れた位置で排水可能な配水管８１が挿入される。この配水管８１には、砂利等の透水材８２等が傾斜面７４、７５、７６及び側壁７２と滑らかな面を形成するように詰め込まれる。この透水材８２により、排水部７９は、傾斜面７４〜７６と段差を有さない。よって、この配水管８１は、流水のみを透水させ、堆積物８３は、透水材８２により排水部７９付近に堆積する。この堆積物８３は、上述の実施例と同様に、次に流水が流入し、一定の流速となった時、排水部７９が傾斜面７４〜７６と段差のない滑らかな面を形成するため、流水の流れの勢いにより、排水部７９から流されて取り除かれる。尚、この排水部７９を用いた場合は、図１４、図１５に示すように配水管８１を貯水槽８５に接続させることにより、排水を貯水槽８５に貯留することができる。
【００３４】
ところで、水路を形成する地域には、水路底面部から流水を浸透させることにより、地盤沈下等が発生する危険性がある地域がある。この水路用ブロック７０は、配水管８１により集水部７８に保有した流水を離れた位置で排水できるので、例えば、水路を地盤沈下等が発生する危険性がある場所に設置する場合でさえも、この配水管８１により地盤沈下の危険性がない安全な位置まで導き排出させることが可能である。
【００３５】
このように、本実施例に係る水路用ブロック７０は、地盤沈下等が発生する危険性がある地域にも適用可能であり、且つそのような地域であっても堆積物が堆積することなく地下に流水を排出可能とするものである。
【００３６】
また、上述のいずれかの水路用ブロックを用いて水路を形成する時は、従来の水路と同様に、隣接する側壁をプレートで固定し、その継ぎ目にはモルタル等の目地材を注入することで実現する。水路には、蓋付タイプ、開放タイプ、ＪＩＳ製品タイプ、大型等があるが、本実施例は、いずれの場合にも適用可能である。
【００３７】
【発明の効果】
上述したように、本発明の水路用ブロック及びこれを用いた水路は、堆積物を堆積させることなく、排水部から流水を排出させることができ、この流水を地下水に供給することができる。よって、簡易な構造で容易に地下水の増量を図ることができるものである。
