【発明の属する技術分野】
この発明は、排水性舗装路面に適用されて、透水性を有する表層から浸透し、不透水性の基層に沿って流下する雨水等を、側溝や排水桝へ排水するための排水構造に関する。
【0002】
【従来の技術】
この種の排水構造として、側溝の溝蓋や排水桝の桝蓋等を受ける金属製の受枠を利用した排水構造がある(特開平10−37286号公報)。そこでは、受枠を表層と面一状に埋設したうえで、表層と隣り合う受枠の立壁部の基端隅部に一群の水抜き穴を通設して、溝蓋や桝蓋の周辺路面での滞水を防止している。特開平10−183728号公報においては、断面L字形の縁石に沿って、下向きに開口するコ字形断面の集水体を表層と面一状に埋設し、集水体内に流入した雨水等を、縁石あるいは側溝に設けた斜めの水抜き穴を介して排水している。集水体は金属製の枠体からなり、その上面および側面にはそれぞれ通水穴が多数通設してある。
【0003】
【発明が解決しようとする課題】
溝蓋や桝蓋用の受枠は、側溝等の現場打設時に側溝と一体化する場合と、成形用金型を用いて側溝ブロックを成形する際に一体化する場合とがある。多くの場合は、工期を短縮するために予め成形した側溝ブロックや桝ブロックを施工現場へ運び込み、これら既成ブロックを組み立てて側溝や排水桝を構築している。このように既成ブロックを用いる場合はもちろん、現場打設によって側溝等を構築する際には、上記のような排水構造をいかに少ない手間で構築するかが問題となる。
【0004】
先の受枠を表層と面一状に埋設するものでは、基層に沿って流下する雨水が受枠に達するまで、雨水を排出できない。そのため、降水量が多いような場合に、表層に滞水を生じやすく、スリップ等を生じやすい。集水体を縁石に沿って埋設する形式では、施工現場において集水体を縁石に対してボルトで締結し、あるいはモルタルを流し込む等により縁石と一体化する必要があるので、その分だけ余分な手間が掛かる。縁石の設置距離と同じ長さの集水体を埋設するので、排水構造の全体コストが高く付く不利もある。受枠の上壁が路面に露出するので、滑りやすく安全性に問題がある。受枠および集水体には、それぞれ一群の通水穴や水抜き穴を通設するので、その分だけ受枠や集水体の耐荷重が減少する不利もある。
【0005】
この発明の目的は、表層に浸透した雨水を速やかに排出できるうえ、構造が簡単で施工に要する手間を削減でき、従って排水構造の構築コストを低減できる排水性舗装路面に好適な排水構造を提供することにある。この発明の他の目的は、排水構造の全体を表層ないし排水設備中に埋設でき、従って排水設備に起因するスリップ等を防止できる安全性に優れた排水構造を提供することにある。この発明の他の目的は、既成ブロックに受枠と排水路とを一体的に設けておくことにより、施工現場において排水構造をより少ない手間で簡単に構築できるうえ、その構成部品を低コストで形成できるようにすることにある。
【0006】
【課題を解決するための手段】
この発明は、排水性の舗装路面Rの路面に設けた排水設備Sに適用される排水構造を対象とする。その排水設備Sは、図1および図2に示すごとくコンクリート製の本体部3と、本体部3にアンカーボルト6を介して一体に固設してある金属製の受枠4と、受枠4に嵌め込み装填される蓋体5とを含む。受枠4は、その上端面が舗装路面Rの表層2の表面と面一状になるよう配置する。表層2内に浸透した雨水等を排水設備内の排水路7へと流下案内するための排水導体10を、路面中央へ向かって突出する状態で、路面側の受枠4に通設した排水通口13の外面に固定する。排水導体10は、周壁に一群の通水口14が開口してある、管材ないし形材からなる金属中空体製の導水体12を含み、その少なくとも一部が表層2中に埋設される。
【0007】
具体的には、既成ブロックからなる本体部3の上端に、受枠4と、表層2の側縁に接する受壁部3aとを内外に隣接する状態で配置する。排水導体10は、路面側の受枠4に固定されて受壁部3aを内外に貫通する支持体11と、表層2の敷設時に支持体11に装填されて表層2中に埋設される導水体12とで構成する。
【0008】
施工現場で、コンクリートを打設して形成される本体部3においては、その上端に、受枠4を本体部3と一体に固設する。表層2の側縁と接する受枠4の立壁4bには先の排水導体10が固定されている。
【0009】
この発明の別の排水構造における排水設備Sは、図3に示すごとくコンクリート製の既成ブロックからなる本体部3と、本体部3の上部に固設されている金属製の受枠4と、受枠4に嵌め込み装填される蓋体5とを含む。舗装路面Rの表層2の側縁と接する本体部3の外面と、本体部3の内面との間に、表層2内に浸透した雨水等を排水路7へ流下案内する排水導体10を、路面中央へ向かって突出する状態で受枠4の下面に固定する。
【0010】
上記の排水導体10は、受枠4に固定されて本体部3の肉壁内に埋設される支持体11と、表層2の敷設時に支持体11に装填されて、表層2中に埋設される導水体12とで構成する。
【0011】
【作用および発明の効果】
例えば管材で形成した排水導体10を予め受枠4に固定しておき、その状態の受枠4をコンクリート製の本体部3にアンカーボルト6を介して一体に固設するので、施工現場において排水構造を構築する際に、受枠4や排水導体10を本体部3や基層1等に対して固定する必要がなく、その分だけ施工の手間を省くことができる。表層2内に浸透した雨水は、基層1の勾配に沿って流下するが、道路中央へ向かって突設した導水体12を介して、雨水を速やかに排水路7へ排出するので、降雨量が多い場合であっても、表層2に滞水するのをよく防止できる。また、雨水の一部は、受枠4にせき止められるが、せき止められた雨水は受枠4に沿って流動し、真近の排水導体10を介して排水路7へと流下排出される。このように受枠4で集水し、受枠4に沿って適当間隔おきに設けた排水導体10を介して排水を行うと、排水部品として排水導体10を付加するだけで済むので、先のように施工の手間を省くことができることも相俟って、全体として排水構造を低コストで構築できる。排水構造の全体を表層2および本体部3に埋設するので、排水構造に起因するスリップ等を防止でき、その分だけ安全性を向上できる。受枠4これ自体に一群の水抜き穴を通設する従来の排水構造に比べて、受枠4の耐荷重が著しく低下することもない。長さが大小に異なる導水体12を使い分けることにより、排水導体10の排水能力を増減できる点でも有利である。
【0012】
既成ブロックからなる本体部3で排水設備Sを構築する場合には、本体部3を成形する際に受枠4を一体に固設する。さらに、排水導体10を支持体11と導水体12とで構成しておき、支持体11を受枠4と共に本体部3に固設する。このようにすると既存のブロック製造金型がそのまま使用できる。導水体12は、表層2を形成する前に支持体11に差し込み装填して、その一部を表層2の積層領域に突出させておく。支持体11は受枠4に予め固定しておくことが望ましく、例えば溶接しておく。このように、支持体11と導水体12とで排水導体10を構成すると、排水構造を構築する際に、支持体11に対して導水体12を単に差し込み装填するだけで排水導体10を形成できるので、施工の手間を省くことができる。支持体11は受壁部3aの肉壁内に埋設されるので、受壁部3aの補強材としても機能する。
【0013】
図4に示すように施工現場でコンクリートを打設して本体部3を形成する場合には、予め排水導体10を受枠4に固定しておき、その状態の受枠4を本体部3の上端にアンカーボルト6を介して本体部3と一体化する。
【0014】
図3に示すように表層2の側縁と接する本体部3の外面と、本体部3の内面との間の肉壁内に、雨水等を流下案内する排水導体10を設け、排水導体10を受枠4の下面に固定する排水構造によれば、受枠4に排水通口13を通設する必要がないので、その分だけ加工の手間を省き、排水構造を低コストで構成できる。本体部3の受壁部3aが省略され、受枠4の立壁4bが表層2の側縁と接する場合にも、排水導体10を支障なく設けることができる。
【0015】
排水導体10を、受枠4に固定される支持体11と、表層2中に埋設される導水体12とで構成すると、表層2の敷設に先行して、導水体12を支持体11に差し込むだけで排水構造を形成でき、従来の排水構造に比べてその構築の手間を省くことができる。
【0016】
【実施例】
(第1実施例)
図1および図2はこの発明に係る排水構造の第1実施例を示す。図2において、符号Rは高速道路等に適用した排水性の舗装路面、Sは路面の路肩に沿って構築された側溝(排水設備)である。舗装路面Rは、水を通さない基層1と、基層1上に積層敷設した水を通す表層2とで構成してある。基層1および表層2は、それぞれ路面中央から路肩へ向かって下り勾配となるように形成される。基層1は路盤上にアスファルト舗装、あるいはコンクリート舗装を施して形成してあり、表層2は連続空隙を有する透水性アスファルト舗装、あるいは透水性コンクリート舗装等を施して形成してある。
【0017】
側溝Sは、既成のコンクリートブロックからなる本体部3と、本体部3の上端に設けた受枠4と、受枠4に嵌め込み装填される溝蓋(蓋体)5とからなる。本体部3は断面U字形のブロックからなり、成形用の金型を用いて工場生産される。
【0018】
図1において受枠4は、直交状に折れ曲がる座壁4aと立壁4bとを有する断面L字形の鋼製枠体からなり、その立壁4bの下端の長手方向数個所にアンカーボルト6を溶接する。さらに、立壁4bの長手方向の数個所には、後述する支持体11を立壁4bと直交する状態で溶接する。
【0019】
雨天時に舗装路面Rに降りそそいだ雨水は、表層2に浸透した後、基層1に受け止められて側溝Sへ向かって流下する。この流下水を滞りなく側溝S内の排水路7へ排出するために、受枠4の長手方向に沿って、排水導体10を道路中央へ向かって突出する状態で一定間隔おきに設ける。排水導体10は、先の受枠4に固定した支持体11と、支持体11に装填されて、表層2の側縁と接する本体部3の受壁部3aより外側方へ突出する導水体12とで構成する。支持体11は断面円形の鋼管を、受壁部3aの厚み寸法と同じ長さに切断して形成してあり、受壁部3aを内外に貫通している。支持体11に臨む立壁4bには、支持体11の内底面に連通する状態で小径の排水通口13が通設してある。導水体12は、支持体11の内直径寸法より僅かに小さな外直径の鋼管からなり、その周壁には多数の通水口14が通設されている。このように既成の鋼管を素材にして、その周壁に丸穴からなる通水口14の一群をドリルで通して形成した導水体12によれば、例えば通水口14が打ち抜いてある板材を管状に曲げて導水体12を形成する場合に比べて、導水体12を低コストで形成できる。
【0020】
溝蓋5は四角形に組まれた基枠5a内に、断面I形の耐力枠5bを一定間隔おきに配置しその両端を基枠5aに溶接して構成してある。溝蓋5の幅寸法は、左右一対の受枠4における立壁4bの対向寸法より小さく設定してあり、従って、溝蓋5を受枠4内に落とし込むだけで、簡単に嵌め込むことができる。
【0021】
側溝Sと舗装路面R、および排水構造は、次の手順で構築する。本体部3を埋設するための溝を開削し、路盤を整備した後、本体部3を溝内に設置して位置決めする。この状態で基層1を形成する。このときの基層1の表面は、受枠4に固定した支持体11の開口面の内底と面一状とするが、僅かに低くなるようにする。基層1を形成した後、本体部3を設置してもよい。次に導水体12を路面の側から支持体11内に差し込み装填し、その大半を基層1上に露出させ、かつ路面中央へ向かって突出させる。この状態で表層2を形成し、導水体12の露出部分を表層2中に埋設する。最後に溝蓋5を受枠4に嵌め込んで側溝を完成する。
【0022】
以上のように、この実施例の排水構造によれば、本体部3を設置した後、導水体12を支持体11に差し込むだけで排水導体10を形成でき、排水構造を構築する際の施工の手間を削減できる。基層1に沿って流れてきた雨水の一部は、導水体12の突端開口や、その周壁に設けた通水口14から導水体12内へ流入し、受枠4に通設した排水通口13を介して受枠4内へ流入し、やがて排水路7へと流下する。表層2に浸透した雨水の一部は基層1の勾配下端において本体部3の受壁部3aにせき止められ、受壁部3aに沿って流動し、真近の導水体12に達した時点で、その排水通口13から導水体12内へ流れ込み、上記のようにして排水路7へ排水される。
【0023】
(第2実施例)
図3はこの発明に係る排水構造の第2実施例を示す。そこでは、第1実施例の排水構造と比べて、排水導体10を受枠4の下面に一体的に配置する点に違いがある。詳しくは、受枠4の下面に支持体11を溶接し、既成のコンクリートブロックからなる本体部3を成形する際に、アンカーボルト6および支持体11を本体部3の肉壁内に埋設する。支持体11の一端は表層2の側縁と接する受壁部3aの外面において開口し、他端は本体部3の内面で開口している。排水導体10は、支持体11と表層2の敷設時に支持される導水体12とからなり、導水体12の殆どの部分は表層2中に埋設される。支持体11の管内面には、導水体12の差し込み限界を規定する突起11aを設けておく。他は第1実施例と同じであり、同一部材に同じ符号を付してその説明を省略する。以下の実施例等においても同じ扱いとする。
【0024】
このように、支持体11を受枠4の下面に溶接すると、受枠4に排水通口13を通設する必要がないので、その分だけ加工の手間を省くことができる。受壁部3aを省略した状態の本体部3を形成する場合であっても、排水導体10を支障なく設けることができる。なお排水導体10は、導水体12を受枠4の下面に溶接して、導水体12のみで形成することができる。この場合には、表層2内に埋設される導水体12の周壁部分に限って通水口14を形成しておけば足りる。
【0025】
(第3実施例)
図4は側溝Sの本体部3が、施工現場において組んだ型枠に生コンクリートを流し込んで形成される場合の排水構造の第3実施例を示す。そこでは、側溝用の溝を開削したのち、路盤上の基層1を形成する。次いで開削した溝の内部に本体部3を形成するための型枠を組む。受枠4は第1実施例と同様に形成し、型枠に固定しておく。この場合の排水導体10は、第1実施例における導水体12のみで形成し、その一端を受枠4の立壁4bに溶接し固定する。このときの基層1は、その表面が排水導体10の下面と面一状になるように形成する。最後に、基層1上に表層2を形成して、排水導体10を表層2内に埋設する。
【0026】
上記のように、施工現場でコンクリートを打設して本体部3を形成する場合には、排水導体10が一体化してある受枠4を型枠に組んだ後、コンクリートを流し込むだけで排水構造を形成できる。換言すると、排水構造を受枠4と一体的に形成しておくので、施工現場では排水構造を形成するための手間を省くことができる。なお、導水体12は立壁4bに対して、圧嵌固定し、あるいはかしめ固定することができる。必要があればねじ込み固定してもよい。
【0027】
排水導体12は、図5(a)・(b)に示すように角パイプや、下向きに開口する断面コ字形の形材等の金属中空体で形成することができる。もちろん、その断面形状は円形や四角形以外の多角形や楕円、あるいは凸字形等の異形断面形状であってもよい。
【0028】
(第4実施例)
図6はこの発明をインターロッキング舗装路面に適用した第4実施例を示す。そこでの表層2は、基層1上に形成した透水性を有する下地層2aと、下地層2aの上面に敷設した表層ブロック2bとで構成し、受枠4に設けた導水体12を表層ブロック2bと基層1との間に埋設した。表層ブロック2bは連続空隙を有する多孔体状のコンクリートブロックからなり、路面に降りそそいだ雨水を速やかに浸透させて、路面での滞水を防止できる。なお、表層ブロック2bは連続空隙を有するれんがや、アスファルトブロックで形成してあってもよい。
【0029】
先の各実施例においては、排水設備Sが側溝である場合について説明したが、この発明の排水構造は、路面に沿って一定間隔おきに設けられる排水桝(排水設備)にも等しく適用できる。その場合の排水桝の本体部3は既成ブロックであってもよく、第3実施例と同様に、現場でのコンクリート打設によって基層1と一体に形成するものであってもよい。また、桝蓋(蓋体)は側溝における溝蓋に相当する。上記以外に、側溝Sの受枠4に縁石を嵌め込む場合には、縁石が本発明で言う蓋体を意味する。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a drainage structure that is applied to a drainage pavement road surface and drains rainwater or the like that permeates from a water-permeable surface layer and flows down along a water-impermeable base layer into a gutter or a drainage basin.
[0002]
[Prior art]
As this type of drainage structure, there is a drainage structure using a metal receiving frame for receiving a gutter of a gutter or a lid of a drainage basin (Japanese Patent Laid-Open No. 10-37286). There, the receiving frame was buried flush with the surface layer, and a group of drainage holes were passed through the base corner of the standing wall of the receiving frame adjacent to the surface layer. To prevent water from stagnating. In Japanese Patent Application Laid-Open No. 10-183728, a water collector having a U-shaped cross section that opens downward along a curb having an L-shaped cross section is buried flush with the surface layer, and rainwater or the like that has flowed into the water collector is curb stone. Alternatively, the water is drained through a diagonal drain hole provided in the side groove. The water collecting body is formed of a metal frame, and a large number of water holes are provided on the top and side surfaces thereof.
[0003]
[Problems to be solved by the invention]
The receiving frame for the groove lid or the box lid may be integrated with the gutter at the time of casting the gutter or the like on site, or may be integrated when forming the gutter block using a molding die. In many cases, in order to shorten the construction period, preformed gutter blocks and pit blocks are carried to the construction site, and these existing blocks are assembled to form gutters and drainage pits. As described above, when constructing a gutter or the like by casting in-situ, as well as using an existing block, how to construct the above-described drainage structure with a small amount of labor becomes a problem.
[0004]
When the above-mentioned receiving frame is buried flush with the surface layer, rainwater cannot be discharged until rainwater flowing down along the base layer reaches the receiving frame. Therefore, when there is a large amount of precipitation, water is easily generated on the surface layer, and slips and the like are easily generated. In the case where the catchment is buried along the curb, the catchment must be bolted to the curb at the construction site or integrated with the curb by pouring mortar, etc. Hang on. Since the water collecting body is buried with the same length as the curb distance, there is a disadvantage that the overall cost of the drainage structure is high. Since the upper wall of the receiving frame is exposed on the road surface, it is slippery and there is a problem in safety. Since a group of water holes and drain holes are provided in the receiving frame and the water collecting body, respectively, there is a disadvantage that the load bearing capacity of the receiving frame and the water collecting body is reduced by that much.
[0005]
SUMMARY OF THE INVENTION An object of the present invention is to provide a drainage structure suitable for a drainable pavement surface capable of rapidly draining rainwater that has permeated the surface layer, having a simple structure and reducing the labor required for construction, and thus reducing the construction cost of the drainage structure. Is to do. Another object of the present invention is to provide a highly safe drainage structure in which the entire drainage structure can be buried in a surface layer or in a drainage facility, and therefore, a slip or the like caused by the drainage facility can be prevented. Another object of the present invention is to integrally form a receiving frame and a drainage channel on a pre-made block, so that a drainage structure can be easily constructed with less labor at a construction site, and its components can be formed at low cost. To be able to do it.
[0006]
[Means for Solving the Problems]
The present invention is directed to a drainage structure applied to drainage equipment S provided on a drainage pavement road surface R. As shown in FIGS. 1 and 2, the drainage device S includes a concrete main body 3, a metal receiving frame 4 integrally fixed to the main body 3 via anchor bolts 6, and fitted into the receiving frame 4. And a lid 5 to be loaded. The receiving frame 4 is arranged so that its upper end surface is flush with the surface of the surface layer 2 of the pavement road surface R. A drainage passage provided in a receiving frame 4 on the road surface side with a drainage conductor 10 for guiding rainwater or the like that has penetrated into the surface layer 2 to a drainage channel 7 in a drainage facility, protruding toward the center of the road surface. 13 on the outer surface. The drainage conductor 10 includes a hollow water-guiding body 12 made of a tubular material or a shape having a group of water-opening ports 14 opened in the peripheral wall, at least a part of which is buried in the surface layer 2.
[0007]
Specifically, a receiving frame 4 and a receiving wall portion 3a that is in contact with a side edge of the surface layer 2 are arranged at the upper end of the main body portion 3 made of a ready-made block so as to be adjacent to the inside and outside. The drain conductor 10 is fixed to the receiving frame 4 on the road surface side and penetrates the receiving wall 3a in and out, and a water guiding body 12 that is loaded on the supporting member 11 when the surface layer 2 is laid and embedded in the surface layer 2. It consists of
[0008]
At the construction site, in the main body 3 formed by casting concrete, a receiving frame 4 is fixedly mounted integrally with the main body 3 at the upper end thereof. The drainage conductor 10 is fixed to the upright wall 4b of the receiving frame 4 in contact with the side edge of the surface layer 2.
[0009]
As shown in FIG. 3, the drainage equipment S in another drainage structure of the present invention includes a main body 3 made of a pre-made block made of concrete, a metal receiving frame 4 fixed on the upper part of the main body 3, and a receiving frame 4. And a lid 5 that is fitted and loaded into the device. A drain conductor 10 that guides rainwater or the like that has permeated into the surface layer 2 to flow down to the drain channel 7 is provided between the outer surface of the main body portion 3 that is in contact with the side edge of the surface layer 2 of the pavement road surface R and the inner surface of the main body portion 3. It is fixed to the lower surface of the receiving frame 4 so as to protrude toward the center.
[0010]
The drainage conductor 10 is fixed to the receiving frame 4 and buried in the wall of the main body 3, and the drainage conductor 10 is loaded on the support 11 when the surface layer 2 is laid, and the water guide buried in the surface layer 2. And the body 12.
[0011]
[Action and effect of the invention]
For example, the drainage conductor 10 formed of a pipe material is fixed to the receiving frame 4 in advance, and the receiving frame 4 in that state is integrally fixed to the concrete main body 3 via the anchor bolts 6, so that the drainage structure is constructed at the construction site. At the time of construction, it is not necessary to fix the receiving frame 4 and the drain conductor 10 to the main body 3 and the base layer 1 and the like, so that the work of construction can be saved by that much. The rainwater that has penetrated into the surface layer 2 flows down along the gradient of the base layer 1, but the rainwater is quickly discharged to the drainage channel 7 through the water guide 12 protruding toward the center of the road. Even if the amount is large, it is possible to prevent the water from staying on the surface layer 2 well. Further, a part of the rainwater is dammed by the receiving frame 4, but the damped rainwater flows along the receiving frame 4 and flows down to the drainage channel 7 through the nearest drainage conductor 10. When water is collected in the receiving frame 4 and drained through the drain conductors 10 provided at appropriate intervals along the receiving frame 4 as described above, it is only necessary to add the drain conductor 10 as a drain component. The drainage structure can be constructed at low cost as a whole, in combination with the fact that the labor for construction can be saved. Since the entire drainage structure is buried in the surface layer 2 and the main body 3, slips and the like caused by the drainage structure can be prevented, and the safety can be improved accordingly. Compared with a conventional drainage structure in which a group of drain holes are provided in the receiving frame 4 itself, the load resistance of the receiving frame 4 is not significantly reduced. It is also advantageous in that the drainage capacity of the drainage conductor 10 can be increased or decreased by selectively using the water guides 12 having different lengths.
[0012]
When constructing the drainage equipment S with the main body 3 composed of a pre-made block, the receiving frame 4 is integrally fixed when the main body 3 is formed. Further, the drain conductor 10 is composed of a support 11 and a water guide 12, and the support 11 is fixed to the main body 3 together with the receiving frame 4. In this case, the existing block manufacturing mold can be used as it is. The water guide 12 is inserted and loaded into the support 11 before forming the surface layer 2, and a part of the water guide 12 is made to protrude into the laminated region of the surface layer 2. The support 11 is desirably fixed to the receiving frame 4 in advance, and is, for example, welded.
