Description

【０００１】
【発明の属する技術分野】
この発明は、道路、道路橋、高架駐車場あるいは飛行場等（以下道路等という）の排水性舗装における排水路に関するものである。
【０００２】
【従来の技術】
道路等の舗装に際しては、排水性表層アスファルトを施工した排水性舗装が普及してきており、雨水の排水を容易にすると共に、舗装部及び路盤（地盤あるいは床版）の保護が計られている。排水性舗装を施工するには、先ず、横断勾配を設けられた路盤の表面に、路肩に沿って排水桝間に溝を形成しつつ不透水性基層アスファルトを敷設し、次に、両側の路肩に沿う溝内に透水性排水管を設置し、その後、透水性排水管及び不透水性基層アスファルトを覆う排水性表層アスファルトを敷設して排水性舗装及び排水路が構成されている。透水性排水管は、排水性舗装材料を充填したコンクリート製あるいは樹脂製の透水性排水管であり、路肩に沿って所定間隔をおいて設けられた排水桝に接続されている。
【０００３】
このように構成される排水性舗装及び排水路を施工された道路等において、その表面に降った雨は、排水性表層アスファルトに侵入する。排水性表層アスファルトに侵入した雨水は不透水性基層アスファルトに遮られて路盤には侵入せず、排水性表層アスファルト内を流動し、排水性表層アスファルトよりも低い位置に配置された透水性排水管へ流入し、透水性排水管内を流動して排水桝へ流入し、排水桝から排水管等へ排水されている。
【０００４】
【発明が解決しようとする課題】
従来の排水性舗装用排水路は以上のように構成されていることにより、次のような課題が存在している。すなわち、透水性排水管は、時間の経過と共に、排水性表層アスファルト内を雨水と共に流れてくるゴミ、土砂等により目詰まりして透水機能が低下し、透水機能を徐々に消失してしまうし、排水性表層アスファルト自体もゴミ、土砂等により目詰まりして排水機能が低下するものである。その結果、雨水の排水時間が長くなり、少量の降雨量でも長時間降雨が続く場合、あるいは、短時間での多量の降雨量があった場合、道路等の表面の凹みの部分あるいは道路の曲線部の小径側に滞水が発生する。そして、このような目詰まりを起こした透過水性排水管および排水性表層アスファルトの透水機能の低下は、清掃等により回復するものではなく、透水機能の回復再生は殆ど不可能である。従って、目詰まりを起こした透水性排水管および排水性表層アスファルトの透水機能の回復には、交換のための工事を行う必要がある。
【０００５】
本発明は以上のような課題を解決するためになされたものであり、目詰まりを起こさず、清掃が容易に実施可能な排水性舗装用排水路を提供することを目的とする。
【０００６】
【課題を解決するための手段】
上記目的を達成するために、本発明による排水性舗装用排水路は以下のように構成されている。すなわち、道路脇の暗渠蓋であるＬ型縁石の道路中心側の側辺に沿って設けられる集水路を、コ字形の下辺より若干短い上辺の開口端が上向きに立ち上がった直立縁を持つ長尺の集水路本体の全高さを、前記Ｌ型縁石の道路中心側側辺高さと一致させるとともに、コ字形の上辺に複数の通水孔を長さ方向に適宜間隔をもって設ける一方、前記コ字形の内部と、前記下辺の開口端と直立縁の側面との間を占める略Ｌ字形の空間に収まる形状にして、前記コ字形の下辺に沿う通水用の欠除部を形成した補強板を、前記集水路本体の長さ方向に適宜間隔をもって複数枚固着した構成とし、この集水路の開口側を、前記Ｌ型縁石の側辺に当接させ、不透水性基層アスファルトを前記集水路本体のコ字形の上辺の高さまで敷設し、その上に、排水性表層アスファルトを前記集水路本体の直立縁の上端まで敷設する。また、前記補強板の代わりに、前記コ字形の内部を占める空間に収まる形状にして、前記コ字形の下辺に沿う通水用の欠除部を形成した補強板を、前記集水路本体の長さ方向に適宜間隔をもって複数枚固着し、前記集水路本体の上・下辺の横方向の長さの差を幅とし、底面に長さ方向に直列する複数の通水小孔を配置した横断面が上向きコ字形の長尺のゴミ取り部材を前記補強板の上に着脱自在に設ける。また、前記集水路内を流れる雨水を前記暗渠に導く排水孔をこの暗渠の適所に設ける。
【０００７】
【発明の実施の形態】
本発明に係わる排水性舗装用排水路の好適な実施の形態について、以下に、図面と共に詳細に説明する。図１は、本発明による排水路の第１実施例を示す斜視断面図、図２は、同じく側面断面図である。
【０００８】
第１実施例は、道路等の横断勾配を設けられて平面状に構成された路盤（１）の脇の暗渠（２）の蓋であるＬ型縁石（３）の道路中心側の側辺（３ａ）に沿って集水路（４）を設ける。集水路（４）は集水路本体（１０）と複数の補強板（２０）よりなる。集水路本体（１０）は、コ字形の下辺（１１）より若干短い上辺（１２）の開口端が上向きに立ち上がった直立縁（１３）を持つ長尺の部材である。この集水路本体（１０）の全高さは、Ｌ型縁石（３）の側辺（３ａ）と高さが一致する。また、コ字形の上辺（１２）に複数の通水孔（１４）を長さ方向に適宜間隔をもって設ける。一方、補強板（２０）は前記コ字形の内部と、下辺（１１）の開口端と直立縁（１３）の側面との間を占める略Ｌ字形の空間に収まる形状にして、コ字形の下辺（１１）に沿う通水用の欠除部（２１）を形成している。この補強板（２０）は集水路本体（１０）の長さ方向に適宜間隔をもって複数枚固着しており、集水路（４）の開口側を、Ｌ型縁石（３）の側辺（３ａ）に当接させる際に、直立縁（１３）と側辺（３ａ）の間に挟まれる。さらに、路盤（１）の上に不透水性基層アスファルト（５）を集水路本体（１０）のコ字形の上辺（１２）の高さまで敷設し、その上に、排水性表層アスファルト（６）を集水路本体（１０）の直立縁（１３）の上端まで敷設し、集水路（４）内を流れる雨水を暗渠（２）に導く排水孔（７）を暗渠（２）の適所に設けている。
【０００９】
集水路本体（１０）は耐蝕性を有する鋼板製長尺部材であり、補強板（２０）も耐蝕性を有する鋼板製である。
【００１０】
このようにして排水性舗装を施工された道路等において、雨天の場合、道路等の表面に降った雨は、排水性表層アスファルト（６）に侵入するものと、排水性表層アスファルト（６）の表面を流動して、Ｌ型縁石（３）側へ向かうものとに分かれ、表面を流動したものは、直立縁（１３）とＬ型縁石（３）の側辺（３ａ）との間から集水路（４）の内部へ流入する。一方、排水性表層アスファルト（６）に侵入した雨水は不透水性基層アスファルト（５）に遮られて路盤（１）には侵入せず、不透水性基層アスファルト（５）の表面に沿い、排水性表層アスファルト（６）内を流動して複数の通水孔（１４）から集水路（４）の内部へ流入する。集水路（４）の内部に流入した雨水は、集水路（４）の流路空間を流れて、排水孔（７）から暗渠（２）に導かれて排水される。
【００１１】
上記のように、通水孔（１４）および、直立縁（１３）とＬ型縁石（３）の側辺（３ａ）との間隙を通じて、流水は集水路（４）内部へ流入し、排水されるため、雨水とともに流動してくるゴミ、土砂等は目詰まりすることなく通過する。尚、直立縁（１３）とＬ型縁石（３）の側辺（３ａ）との間隙に大きなゴミ、土砂等が詰まった場合は、簡単に外部から清掃できる。
【００１２】
図３は、本発明による排水路の第２実施例を示す斜視断面図、図４は、同じく側面断面図である。
【００１３】
第２実施例は、道路等の横断勾配を設けられて平面状に構成された路盤（１）の脇の暗渠（２）の蓋であるＬ型縁石（３）の道路中心側の側辺（３ａ）に沿って集水路（４）を設ける。集水路（４）は集水路本体（１０）と複数の補強板（２０）とゴミ取り部材（３０）よりなる。集水路本体（１０）は、コ字形の下辺（１１）より若干短い上辺（１２）の開口端が上向きに立ち上がった直立縁（１３）を持つ長尺の部材である。この集水路本体（１０）の全高さは、Ｌ型縁石（３）の側辺（３ａ）と高さが一致する。また、コ字形の上辺（１２）に複数の通水孔（１４）を長さ方向に適宜間隔をもって設ける。一方、補強板（２０）は前記コ字形の内部の空間に収まる形状にして、コ字形の下辺（１１）に沿う通水用の欠除部（２１）を形成している。この補強板（２０）は集水路本体（１０）の長さ方向に適宜間隔をもって複数枚固着している。また、ゴミ取り部材（３０）は、集水路本体（１０）の上辺（１２）と下辺（１１）の横方向の長さの差を幅とし、底面（３１）に長さ方向に直列する複数の通水小孔（３２）を配置した横断面が上向きコ字形の長尺の部材であり、その両側面（３３）の間隔を保持するために、間隔保持具（３４）を適宜間隔に設けている。このゴミ取り部材（３０）は集水路（４）の開口側を、Ｌ型縁石（３）の側辺（３ａ）に当接させる際に、直立縁（１３）と側辺（３ａ）の間に挟まれる恰好で補強板（２０）の上に着脱自在に装着される。さらに、路盤（１）の上に不透水性基層アスファルト（５）を集水路本体（１０）のコ字形の上辺（１２）の高さまで敷設し、その上に、排水性表層アスファルト（６）を集水路本体（１０）の直立縁（１３）の上端まで敷設し、集水路（４）内を流れる雨水を暗渠（２）に導く排水孔（７）を暗渠（２）の適所に設けている。
【００１４】
集水路本体（１０）は耐蝕性を有する鋼板製長尺部材であり、補強板（２０）も耐蝕性を有する鋼板製である。ゴミ取り部材（３０）も耐蝕性を有する鋼板製である。
【００１５】
このようにして排水性舗装を施工された道路等において、雨天の場合、道路等の表面に降った雨は、ほぼ第１実施例中に記述した流れで、集水路（４）に集められ、流路空間を流れて、排水孔（７）から暗渠（２）に導かれて排水されるが、異なっている点は、直立縁（１３）とＬ型縁石（３）の側辺（３ａ）との間から集水路（４）の内部へ流入するものが、ゴミ取り部材（３０）の通水小孔（３２）を経過して流入することである。
【００１６】
上記のように、通水孔（１４）および、ゴミ取り部材（３０）の通水小孔（３２）を通じて、流水は集水路（４）内部へ流入し、排水されるため、雨水とともに流動してくるゴミ、土砂等は目詰まりすることなく通過する。尚、ゴミ取り部材（３０）内に大きなゴミ、土砂等が詰まった場合は、簡単にゴミ取り部材（３０）ごと取り外して捨てることができ簡単に清掃できる。清掃した後のゴミ取り部材（３０）は再び元の位置に戻すものである。
【００１７】
【発明の効果】
この発明は、以上説明したような形態で実施され、以下に記載されるような効果を奏する。
【００１８】
道路脇の暗渠蓋であるＬ型縁石の道路中心側の側辺に沿って設けられる集水路を、コ字形の下辺より若干短い上辺の開口端が上向きに立ち上がった直立縁を持つ長尺の集水路本体の全高さを、前記Ｌ型縁石の道路中心側側辺高さと一致させるとともに、コ字形の上辺に複数の通水孔を長さ方向に適宜間隔をもって設ける一方、前記コ字形の内部と、前記下辺の開口端と直立縁の側面との間を占める略Ｌ字形の空間に収まる形状にして、前記コ字形の下辺に沿う通水用の欠除部を形成した補強板を、前記集水路本体の長さ方向に適宜間隔をもって複数枚固着した構成とし、この集水路の開口側を、前記Ｌ型縁石の側辺に当接させ、不透水性基層アスファルトを前記集水路本体のコ字形の上辺の高さまで敷設し、その上に、排水性表層アスファルトを前記集水路本体の直立縁の上端まで敷設し、前記集水路内を流れる雨水を前記暗渠に導く排水孔を該暗渠の適所に設ける。また、前記補強板の代わりに、前記コ字形の内部を占める空間に収まる形状にして、前記コ字形の下辺に沿う通水用の欠除部を形成した補強板を、前記集水路本体の長さ方向に適宜間隔をもって複数枚固着し、前記集水路本体の上・下辺の横方向の長さの差を幅とし、底面に長さ方向に直列する複数の通水小孔を配置した横断面が上向きコ字形の長尺のゴミ取り部材を前記補強板の上に着脱自在に設けることにより、ゴミ、土砂等が集水路を目詰まりさせることがなくなり、透水機能が低下することなく、長期間効率良く排水される。
【００１９】

BACKGROUND OF THE INVENTION
The present invention relates to a drainage channel in drainage pavement such as roads, road bridges, elevated parking lots, airfields (hereinafter referred to as roads).
[0002]
[Prior art]
In pavement of roads and the like, drainage pavement with drainage surface layer asphalt has become widespread, facilitating drainage of rainwater and protecting the pavement and roadbed (ground or floor slab). In order to construct drainage pavement, first of all, the impermeable base layer asphalt is laid on the surface of the roadbed with a transverse gradient along the road shoulder while forming a groove between drainage basins, A drainage pavement and a drainage channel are configured by installing a water permeable drain pipe in a groove extending along the line, and then laying a drainable surface layer asphalt covering the water permeable drain pipe and the impermeable base layer asphalt. The water permeable drain pipe is a water permeable drain pipe made of concrete or resin filled with a drainable pavement material, and is connected to a drainage basin provided at a predetermined interval along the road shoulder.
[0003]
In the road etc. where the drainage pavement and the drainage channel constructed as described above are constructed, the rain that has fallen on the surface enters the drainage surface asphalt. Rainwater that has entered the drainage surface asphalt is blocked by the impervious base layer asphalt and does not enter the roadbed. , Flows in the permeable drainage pipe, flows into the drainage basin, and is drained from the drainage basin to the drainage pipe.
[0004]
[Problems to be solved by the invention]
Since the conventional drainage pavement drainage channel is configured as described above, the following problems exist. In other words, the water-permeable drainage pipe is clogged with dust, earth and sand flowing along with the drainage water asphalt with time, and the water-permeable function is reduced, and the water-permeable function gradually disappears. The drainage surface asphalt itself is also clogged with dust, earth and sand, and the drainage function deteriorates. As a result, the drainage time of rainwater becomes long, and even if a small amount of rainfall continues for a long time, or when there is a large amount of rainfall in a short time, a concave portion on the surface of a road or a curve of the road Water stagnates on the small diameter side of the section. And the fall of the water permeability function of the permeable drainage pipe and drainage surface layer asphalt which caused such clogging is not recovered by cleaning etc., and recovery and regeneration of the water permeability function are almost impossible. Therefore, in order to restore the water-permeable function of the water-permeable drainage pipe and the drainage surface asphalt that have been clogged, it is necessary to perform replacement work.
[0005]
The present invention has been made in order to solve the above-described problems, and an object of the present invention is to provide a drainage pavement drainage channel that can be easily cleaned without causing clogging.
[0006]
