Description

【０００１】
【発明の属する技術分野】
この発明は雨水等の排水のために車道の側縁において、歩道の縁石に沿って設置する側溝用ブロックに関するものである。
【０００２】
【発明が解決しようとする課題】
近年、自動車のすべり抵抗性や視認性の向上等の交通安全対策および自動車騒音低減を目的として排水性舗装が広く採用されている。
【０００３】
ところで、通常、車道と歩道からなる街路は、Ｌ形状側溝を通した雨水を所要間隔に設置した桝に集水し、さらに導水管を経由して歩道に設置した排水路にて排水されるという二重経路になっており、施工及びメンテナンスに手間を要するものであった。
【０００４】
そこで、車道の側縁において縁石に沿って側溝用ブロックを設置し、この側溝用ブロックを排水路として車道および歩道の排水を行うという方式が採用されているが、例えば、それに使用される側溝用ブロックとして実公平６−３７１１２号をみることができる。
【０００５】
しかしながら、上記考案では、水抜き穴が蓋体部分しか設けられていないので、車道及び歩道からの排水を充分行うことができない、等の難点があった。
【０００６】
この発明は上記事情に鑑み開発されたもので、車道及び歩道からの排水を円滑に行うことができ、かつ、ブロックどうしの連結が強固になるような側溝用ブロクを提供することを目的としている。
【０００７】
【課題を解決するための手段】
前記目的を達成するために、この発明では、天板部と歩道側壁及び車道側壁とから逆Ｕ字状に形成し、天板部の長手方向中央部に蓋体載置用穴を穿設し、かつ、天板部に歩道側方向に向け傾斜をつけて本体を形成して、前記蓋体載置用穴に蓋体を載置した側溝用ブロックにおいて、天板部に蓋体載置用穴を穿設することで天板部の歩道側縁に形成される細長状部の上面に蓋体載置用穴に連通する水平の通水用凹溝を設け、蓋体の歩道側縁には前記通水用凹溝に一致する位置に水抜き用切欠きを設け、天板部の長手方向の両端部における歩道側縁には、さらに天板部と歩道側壁がなす隅角部に内外連通する水抜き孔を穿設し、車道側壁には壁内外に連通する水抜き孔を穿設し、前記歩道側の水抜き孔は、天板部の表面に凹部を設け、この凹部に開口するように天板部と歩道側壁がなす隅角部に斜めに穿設して内側に開口し、さらに、車道側の水抜き孔は、車道側壁の上部から斜めに壁内側に開口するよう形成したことを特徴としたものである。
また、本体の長手方向の両端に位置する端面部分には、歩道側壁と車道側壁のそれぞれに沿って下端から天板部に開口する縦溝が設けてあり、天板部の左、右側部にはそれぞれ前記縦溝に直交する横溝を設ける。
また、蓋体はその幅方向の一側縁に沿って水抜き用切欠を設ける。
【０００８】
【発明の実施の形態】
以下、図示した実施の形態例に基いて説明する。１はこの発明の側溝用ブロックの本体を示すものであり、本体１は逆Ｕ字状に所要の長さに形成したものであり、２は車道側の側壁を示し、３は歩道側の側壁を示すものであり、車道側の側壁２は歩道側の側壁３に比べてより高い寸法に形成されている。
【０００９】
側壁２，３の上端間には天板部４が歩道側方向に勾配を付けて跨設してあり、側壁２，３の上端部と、天板部４とがなす左，右隅角部には、それぞれハンチ５，５が形成してあり、天板部４の長手方向中央部には天板部全体のおよそ半分を占める大きさの長方形状の蓋体載置用穴６が穿設してある。そして、この蓋体載置用穴６の長手方向側縁に沿って前記ハンチ５の上面が表出し蓋体載置部７となている。また、天板部４には、歩道側縁に沿って角型に切欠いた歩道境ブロック載設用の切欠８が設けてある。
【００１０】
本体１の端面部分には、縦溝９及び横溝１０が設けてある。縦溝９は側壁２，３のそれぞれに沿って下端から天板部４に開口するように設けてあり、横溝１０は天板部４の左，右側部にそれぞれ設けてあって、前記縦溝９と直交して十字状の凹溝となっている。
【００１１】
天板部４の歩道側縁に沿って通水用凹溝１１が設けてある。この通水用凹溝１１は断面台形状に形成され、蓋体載置用穴６に沿う細長状部に２個所設けてあり、蓋体載置用穴６に連通している。
【００１２】
また、天板部４において、歩道側縁に沿う両端部寄りには、それぞれ水抜き孔１２が穿設してある。
【００１３】
この水抜き孔１２部分は、天板部４の表面に長方形状の凹部１２ａを設け、この凹部１２ａに開口する丸孔１２ｂを、天板部４と歩道側の側壁３がなす内側隅角部に開口するように斜めに連通させて穿設したものである。
【００１４】
一方、車道側の側壁２の両端部寄りには、それぞれ水抜き孔１３が穿設してある。この水抜き孔１３は側壁２の上端に設けた膨出部から側壁２と天板４がなす隅角部寄りに開口するように斜めに連通させて穿設したものである。
【００１５】
図１において記号１４は前記本体１の蓋体載置用穴６に載置する蓋体を示すものである。この蓋体１４は２個で一対となり蓋体載置用穴１０を閉塞する大きさの長方形状に形成してあり、その歩道側縁の中央部には、前記本体１の通水用凹溝１１に一致する位置に台形状の水抜き用切欠き１５が設けてあり、また、幅方向の一側縁には、歩道側端部から車道側中間部にかけて細長状の水抜き用切欠き１６が設けてある。
【００１６】
施工に際しては図１に示すように、歩道側に側壁３を向けて設置し、設置個所には割栗石１７を敷設し、基礎コンクリート１８及びインバートコンクリート１９を打設し水路を形成する。また歩道境ブロック載設用の切欠８には歩道境ブロック２０を載設する。
【００１７】
【発明の効果】
以上、この発明では、蓋体部分だけでなく、本体部分にも通水用凹溝、及び水抜き孔が設けてあるので、雨水の排水を早急、かつ、効果的に行うことができる。しかもこれらは歩道側と車道側の両側部に設けてあるので、車道及び歩道からの雨水に対して充分対処できる。
【００１８】
特に、車道側の水抜き孔は表面より若干下がった位置に開口されているために車道面より浸透した雨水の排水を行うことができ、歩道側の水抜き孔の開口表面には凹溝を設けてあるので雨水の集水を円滑に行うことができる。
【００１９】
また、水抜き孔は内側に向けて斜めに連通されているため、雨水を急速、かつ、スムースに水路へと排水することができる。
【００２０】
さらに、本体の端面部分に十字状の凹溝を設け、ブロックどうしの連結に際して、凹溝内にモルタルを注入して行うように形成してあるので、ブロックどうしの連結は強固であり、不同沈下によりずれる恐れはない。
