Description

【０００１】
【発明の属する技術分野】
本発明は道路外側に設けられて優れた排水性能を有す街渠の構造に関するものである。
【０００２】
【従来の技術】
道路の外側には側溝が設けられ、路面に降った雨水を流すことが出来る。図６は従来の一般的な側溝断面を示している具体例であり、車道（イ）と歩道（ロ）の境には境界ブロック（ハ）、（ハ）・・が配列される。そして、車道（イ）の側端には側溝ブロック（ホ）、（ホ）・・を据付し、該車道（イ）に降った雨水を側溝ブロック（ホ）へ流し落とすことが出来る。
【０００３】
側溝ブロック（ホ）は概略Ｕ型断面を成して、上部開口には上蓋（ヘ）が被覆され、該上蓋（ヘ）に設けている穴から路面の雨水が側溝ブロック（ホ）へ流れ落ちる。車道（イ）の路面は側溝へ流れるように外側が僅かに低く成って、上蓋（ヘ）の穴から流れ易くなっている。
【０００４】
ところで、車道（イ）の側端部を車両が走行する場合、又車両が停止する為に側端部に寄る場合、上蓋（ヘ）に溜まっている雨水が跳ね上がり、歩道（ロ）を歩いている歩行者にかかる場合がある。該上蓋（ヘ）は小さな穴が開いた一種のメザラであり、車両が走行する際に被覆されただけの上蓋（ヘ）は跳ね上がって側溝ブロックから外れることがある。
【０００５】
又、車道に横断歩道を設ける場合、穴の開いた上記上蓋（ヘ）が該横断歩道の入口部に存在することで歩き難い。そして、車椅子に乗った身体障害者が横断歩道を渡る際に、車輪が上蓋の穴に嵌まるといった事態が発生する。
【０００６】
図７も従来の側溝断面を示す具体例であるが、該側溝ブロック（ト）は四角形断面を成して内部には水路（チ）を有している。車道（イ）はその上部が透水層（リ）にて構成されている為に、路面に降った雨水は該透水層（リ）に浸透すると共に、透水層（リ）の内部を流れて流入口（ヌ）から側溝ブロック（ト）に入り、水路（チ）へ流れ落ちる。そして、側溝ブロック（ト）の上面（ル）は傾斜している為に、透水層（リ）に浸透しない雨水は上面（ル）に溜まることに成る。
【０００７】
従って、上面（ル）に雨水を通す穴が存在しないことで横断歩道部では歩き易いが、雨が降るときには該上面に雨水が溜まる為に問題を残す。勿論、該側溝ブロック（ト）の上を車両が通過する際には、溜まった雨水が跳ね上がって歩行者にかかる。
【０００８】
【発明が解決しようとする課題】
このように、従来の側溝には上記のごとき問題がある。本発明が解決しようとする課題はこの問題点であり、車道側端部に雨水が溜まることなく、しかも該側端部をバイクや自転車が走行し易く、また横断歩道を渡る際に支障を来たすことのない排水性街渠の構造を提供する。
【０００９】
【課題を解決する為の手段】
本発明に係る排水性街渠の構造は、車道の側端と成る路肩を透水性コンクリートにて構成し、該路肩の下方に側溝ブロックを配置している。従って、該透水性コンクリートに雨水が浸透して側溝へ流れ落ちる構造と成っている。透水性コンクリートである為に、雨水を側溝へ流れ落とす為の大きな穴はなく、内部に形成される無数の空隙を流れることが出来る。ここで、路肩部は側溝ブロックの上部に透水性コンクリートを打設して設けることが出来、又は独立した路肩ブロックとして別途製作したものを側溝ブロックの上に被覆する場合もある。
【００１０】
そして、本発明では車道の側端部に限らず、歩道の排水を行うことが出来るように構成している。歩道の上層を同じく透水性コンクリートによって構成し、歩道面に降った雨水は該透水性コンクリートを通過して側溝ブロックの水路へ流れ落ちる。以下、本発明に係る実施例を図面に基づいて詳細に説明する。
【００１１】
【実施例】
図１は本発明に係る排水性街渠の構造を示している実施例であり、側溝ブロック４の中央には円形断面の水路９が設けられ、該側溝ブロック４は基礎材５の上にモルタル層６を介して正しく据付けられ、そして側溝ブロック上面１４は中央の入口１０側を低くして傾斜し、該側溝ブロック４の上部には排水性コンクリートから成る路肩７を形成している。
【００１２】
そこで、車道１の路面に降った雨水は該路面から傾斜した上面８を有す路肩７へ流れて歩車道境界ブロック３との間に溜まり、該雨水は透水性コンクリートから成る路肩７に浸透して入口１０から水路９へ流れ落ちる。ここで、透水性コンクリートとは砂の比率を多くした多孔質から成るコンクリートであり、内部の隙間を通過して雨水は流れることが出来る。
【００１３】
上記路肩７は入口１０に透水性ブロック１１を嵌めた状態で、側溝ブロック４の上部に直接透水性コンクリートを打設しているが、別途製作した路肩ブロックを設置することも可能である。図２は路肩ブロック１５を車道１の路肩に配置した場合であり、該路肩ブロック１５は下側に不透水性コンクリート層１６、上側には透水性コンクリート層１７を有した２重構造と成っている。
【００１４】
図２では側溝ブロックを示していないが、路肩ブロック１５の下方に設けられて雨水を流すことが出来る。図３は本発明に係る排水性街渠の構造を適用した具体例を示している。同図の１は車道、２は歩道を示し、車道１と歩道２の境界には歩車道境界ブロック３が配置され、そして地中には側溝ブロック４が埋設されている。側溝ブロック４は円形の水路９を形成して、車道１及び歩道２に降った雨水を回収して流すことが出来、コンクリートで固めた基礎材５の上にモルタル層６を介在して該側溝ブロック４が所定の位置に据付けられている。
【００１５】
車道１の側端部と成る路肩７は透水性コンクリートが打設され、路肩上面８は歩車道境界ブロック側へ傾斜している。従って、車道１の路面に降った雨水は路肩７へ流れ、該路肩７の透水性コンクリートを通過して側溝ブロック４の水路９へ流れ落ちる。側溝ブロック４の上に透水性コンクリートが打設され、水路９の上部に設けた入口１０には透水性ブロック１１が嵌まっている。該路肩７の下側には不透水性のコンクリート層が設けられ、全ての雨水が水路９へ流れ落ちるように成っている。
【００１６】
一方、歩道２の上層１２も透水性コンクリートで構成され、歩道面に降った雨水は上層１２の内部を流れて側溝ブロック４の水路９へ流れ落ちる。この具体例に示す排水性街渠の構造は、車道１の路肩７から歩道２にかけて透水性コンクリート層が連続して設けられ、該透水性コンクリート層の内部を通過して雨水が流れ、側溝ブロック４の水路９に回収されて流れる。
【００１７】
図４は本発明に係る他の具体例であり、この排水性街渠の構造は前記図３に示した場合とほぼ同じである。前記具体例の場合には歩道２が車道１に比較して高く成っているが、図４の実施例では車道１と歩道２は同じ高さになっている。
車道１の側端部には路肩７が設けられて透水性コンクリートが打設され、路肩上面８は歩車道境界ブロック側へ傾斜している。従って、車道１の路面に降った雨水は路肩７へ流れ、該路肩７の透水性コンクリートを通過して側溝ブロック４の水路９へ流れ落ちる。
【００１８】
一方、歩道２の上層１２も透水性コンクリートで構成され、歩道面に降った雨水は上層１２の内部を流れて側溝ブロック４の水路９へ流れ落ちる。路肩７と歩道２の上層１２は連続していて、側溝ブロック４の上には透水性コンクリートが打設され、水路９の上部に設けた入口１０には透水性ブロック１１が嵌まっている。路肩７を通過した雨水は入口１０から水路９に流れ落ち、該路肩７の下側には不透水性のコンクリート層が設けられている為に、全ての雨水が水路へ流れ落ちるように成っている。そして、歩車道境界ブロック３は側溝ブロック４の上に打設された透水性コンクリート上に配置されている。
【００１９】
図５は本発明に係る排水性街渠の構造を示している別の具体例である。上記と同じく、同図の１は車道、２は歩道を示し、車道１と歩道２の境界には歩車道境界ブロック３が配置され、そして地中には側溝ブロック４が埋設されている。側溝ブロック４は円形の水路９を形成して車道１及び歩道２に降った雨水を回収して流すことが出来、コンクリートで固めた基礎材５の上にモルタル層６を介在して該側溝ブロック４が所定の位置に据付けられている。
【００２０】
車道１の側端部と成る路肩７には透水性コンクリートが打設され、路肩上面８は歩車道境界ブロック側へ傾斜している。従って、車道１の路面に降った雨水は路肩７へ流れ、該路肩７の透水性コンクリートを通過して側溝ブロック４の水路９へ流れ落ちる。側溝ブロック４の上に設けられる路肩７は透水性コンクリートが打設され、水路９の上部に設けた入口１０には透水性ブロック１１が嵌まっている。路肩７を通過した雨水は入口１０から水路９に流れ落ちる。
【００２１】
一方、歩道２の上層１２も透水性コンクリートで構成され、歩道面に降った雨水は上層１２の内部を流れて側溝ブロック４の水路９へ流れ落ちる。すなわち、上層１２は歩車道境界ブロック３に沿って下方へ下端まで延び、そして歩車道境界ブロック３の下端部には連通穴１３がほぼ水平に貫通している。連通穴１３は歩道側上層１２を構成する透水性コンクリートと路肩７を構成する透水性コンクリートを繋ぎ、歩道に降った雨水は上層１２の透水性コンクリート内部を流れ、連通穴１３を通過し、そして路肩７の透水性コンクリートから入口１０に入って水路へ流れ落ちる。
【００２２】
以上述べたように、本発明の排水性街渠の構造は、車道の路肩を透水性コンクリートにて構成し、その下方に側溝ブロックを配置したものであり、次のような効果を得ることが出来る。
【００２３】
【発明の効果】
本発明は路肩を透水性コンクリートで構成している為に、歩車道境界ブロックとの間に雨水が溜まることはなく、該雨水は路肩に浸透して側溝ブロックの水路へ流れ落ちることが出来る。従って、車両が路肩へ寄って停車する場合や路肩を通過する際に、雨水が跳ね上がって歩道を歩く人にかかることはない。そして、歩道に降った雨水は上層の透水性コンクリートを流れて側溝へ流れ落ちる為に、該歩道面にも雨水が溜まることはなく、歩き易くなる。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a street culvert structure provided outside a road and having excellent drainage performance.
[0002]
[Prior art]
A gutter is provided on the outside of the road to allow rainwater falling on the road surface to flow. FIG. 6 is a specific example showing a conventional general gutter cross section. Boundary blocks (c), (c),... Are arranged at the boundary between the road (a) and the sidewalk (b). Further, gutter blocks (e), (e),... Are installed at the side ends of the roadway (a), and the rainwater falling on the roadway (a) can flow down to the gutter block (e).
[0003]
The gutter block (e) has a substantially U-shaped cross section, and the upper opening is covered with an upper lid (f), and rainwater on the road surface flows down from the hole provided in the upper lid (f) to the gutter block (e). The road surface of the roadway (a) is slightly lower on the outside so as to flow into the side gutter, and is easy to flow from the hole in the upper lid (f).
[0004]
By the way, when the vehicle runs on the side edge of the roadway (a), or when the vehicle approaches the side edge to stop, the rainwater accumulated in the upper lid (f) jumps up and walks on the sidewalk (b). Pedestrians may be affected. The upper lid (F) is a kind of a mezzanine having a small hole, and the upper lid (F), which is merely covered when the vehicle travels, may jump up and come off the gutter block.
[0005]
In addition, when a pedestrian crossing is provided on a road, it is difficult to walk because the upper lid (f) with a hole is present at the entrance of the pedestrian crossing. Then, when a physically handicapped person in a wheelchair crosses a pedestrian crossing, a situation occurs in which wheels are fitted into holes in the upper lid.
[0006]
FIG. 7 is also a specific example showing a conventional gutter cross section. The gutter block (g) has a rectangular cross section and has a water channel (h) inside. Since the upper part of the road (a) is composed of a permeable layer (ri), rainwater falling on the road surface permeates into the permeable layer (ri) and flows inside the permeable layer (ri). Enter the gutter block (g) from the entrance (nu) and flow down to the waterway (h). Since the upper surface (L) of the side groove block (G) is inclined, rainwater that does not penetrate into the permeable layer (R) accumulates on the upper surface (L).
[0007]
Therefore, it is easy to walk on the pedestrian crossing because there is no hole on the upper surface (L) through which rainwater passes, but there is a problem because rainwater accumulates on the upper surface when it rains. Of course, when the vehicle passes over the gutter block (g), the accumulated rainwater jumps up and hits the pedestrian.
[0008]
[Problems to be solved by the invention]
As described above, the conventional side grooves have the above-described problems. The problem to be solved by the present invention is this problem, in which rainwater does not accumulate on the side end of the road, and it is easy for motorcycles and bicycles to run on the side end, and there is an obstacle when crossing a crosswalk. To provide a drainage street culvert structure without any problems.
[0009]
[Means for solving the problem]
In the structure of the drainage street culvert according to the present invention, a road shoulder which is a side end of the road is made of permeable concrete, and a gutter block is arranged below the road shoulder. Therefore, rainwater permeates the permeable concrete and flows down into the gutter. Since it is permeable concrete, there is no large hole for rainwater to flow down into the gutter, and it can flow through countless voids formed inside. Here, the road shoulder portion can be provided by casting permeable concrete on the upper portion of the gutter block, or a separately manufactured independent shoulder block may be coated on the gutter block.
[0010]
In the present invention, the drainage is not limited to the side end of the road, but can be drained from the sidewalk. The upper layer of the sidewalk is also made of permeable concrete, and the rainwater falling on the side of the sidewalk passes through the permeable concrete and flows down to the channel of the gutter block. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.
[0011]
【Example】
FIG. 1 is an embodiment showing the structure of a drainage street culvert according to the present invention. A waterway 9 having a circular cross section is provided at the center of a gutter block 4, and the gutter block 4 is provided on a base material 5 by mortar. The gutter block upper surface 14 is correctly installed via the layer 6 and slopes with the central entrance 10 side down, forming a shoulder 7 of drainage concrete at the top of the gutter block 4.
[0012]
Then, the rainwater falling on the road surface of the road 1 flows to the shoulder 7 having the upper surface 8 inclined from the road surface and accumulates between the road surface boundary block 3 and the rainwater permeates the road shoulder 7 made of permeable concrete. From the entrance 10 to the waterway 9. Here, the permeable concrete is a concrete made of porous material having a large ratio of sand, and rainwater can flow through internal gaps.
[0013]
The above-mentioned road shoulder 7 is formed by laying permeable concrete directly on the upper part of the gutter block 4 with the water-permeable block 11 fitted in the entrance 10. However, it is also possible to install a separately manufactured road shoulder block. FIG. 2 shows a case where the road shoulder block 15 is arranged on the road shoulder of the road 1. The road shoulder block 15 has a double structure having a water-impermeable concrete layer 16 on the lower side and a water-permeable concrete layer 17 on the upper side. I have.
[0014]
Although the gutter block is not shown in FIG. 2, the gutter block is provided below the roadside block 15 to allow rainwater to flow. FIG. 3 shows a specific example to which the structure of the drainage street culvert according to the present invention is applied. In FIG. 1, reference numeral 1 denotes a road, and 2 denotes a sidewalk. A sidewalk boundary block 3 is disposed at the boundary between the road 1 and the sidewalk 2, and a gutter block 4 is buried in the ground. The gutter block 4 forms a circular waterway 9 so that rainwater that has fallen on the road 1 and the sidewalk 2 can be collected and allowed to flow, and the gutter block 6 is interposed on a foundation material 5 hardened with concrete with a mortar layer 6 interposed therebetween. Block 4 is installed at a predetermined position.
[0015]
A road shoulder 7 serving as a side end of the roadway 1 is cast with permeable concrete, and a road shoulder upper surface 8 is inclined toward the sidewalk block. Therefore, the rainwater that has fallen on the road surface of the road 1 flows to the road shoulder 7, passes through the permeable concrete of the road shoulder 7, and flows down to the water channel 9 of the gutter block 4. A permeable concrete is cast on the gutter block 4, and a permeable block 11 is fitted in an entrance 10 provided above the water channel 9. An impermeable concrete layer is provided below the shoulder 7 so that all rainwater flows down to the waterway 9.
[0016]
On the other hand, the upper layer 12 of the sidewalk 2 is also made of permeable concrete, and the rainwater falling on the side of the sidewalk flows inside the upper layer 12 and flows down to the water channel 9 of the gutter block 4. In the structure of the drainage street culvert shown in this specific example, a permeable concrete layer is provided continuously from the shoulder 7 of the road 1 to the sidewalk 2, rainwater flows through the inside of the permeable concrete layer, and the gutter block The water is collected in the water channel 9 and flows.
[0017]
FIG. 4 shows another embodiment according to the present invention. The structure of the drainage street culvert is almost the same as that shown in FIG. In the case of the specific example, the sidewalk 2 is higher than the roadway 1, but in the embodiment of FIG. 4, the roadway 1 and the sidewalk 2 are at the same height.
A road shoulder 7 is provided at a side end of the road 1 and permeable concrete is cast therein, and a road shoulder upper surface 8 is inclined toward the sidewalk block. Therefore, the rainwater that has fallen on the road surface of the road 1 flows to the road shoulder 7, passes through the permeable concrete of the road shoulder 7, and flows down to the water channel 9 of the gutter block 4.
[0018]
On the other hand, the upper layer 12 of the sidewalk 2 is also made of permeable concrete, and the rainwater falling on the side of the sidewalk flows inside the upper layer 12 and flows down to the water channel 9 of the gutter block 4. The road shoulder 7 and the upper layer 12 of the sidewalk 2 are continuous with each other, and permeable concrete is cast on the gutter block 4, and a permeable block 11 is fitted in an entrance 10 provided in an upper part of the waterway 9. The rainwater that has passed through the road shoulder 7 flows down from the entrance 10 into the water channel 9, and since an impermeable concrete layer is provided below the road shoulder 7, all the rainwater flows down into the water channel. And the sidewalk boundary block 3 is arrange | positioned on the water permeable concrete cast on the gutter block 4. As shown in FIG.
