Description

本発明は、路床上に不透水性下地層と透水性の表層を形成した排水性舗装道路に使用する側溝ブロックに関するものである。   The present invention relates to a gutter block used for a drainage paved road in which a water-impermeable base layer and a water-permeable surface layer are formed on a road bed.

昨今、路面に降った雨水を透水性の表層内に浸透させ、これを側溝内に流入させる排水性舗装工法による道路が広く施工されている。このような舗装道路に関しては、実用新案登録第3005384号公報の図5のように、側溝ブロックの外側面に長手方向の全長に亘って開口部の広い断面三角形状の導水溝を形成し、この導水溝内に表層中に浸透した雨水を流入させ、更に導水溝から側溝ブロック内の排水路に通ずる排水孔より排水路内に流入させる方式のもが開発された。   Recently, roads using a drainage pavement method in which rainwater that has fallen on a road surface penetrates into a water-permeable surface layer and flows into a lateral groove have been widely constructed. For such a paved road, as shown in FIG. 5 of Utility Model Registration No. 3005384, a water guide groove having a triangular section with a wide opening is formed on the outer surface of the side groove block over the entire length in the longitudinal direction. A method has also been developed in which rainwater that has permeated into the surface layer is allowed to flow into the water ditches, and further flows into the drainage channel from the drainage holes that lead to the drainage channel in the side channel block.

この方式にあっては、舗装作業時に表層の素材である砕石が、開口部が広い導水溝内に嵌入し、表層に浸透した雨水を排水させることができなくなる欠点がある。   In this method, there is a drawback that crushed stone, which is a material of the surface layer, is inserted into a water guide groove with a wide opening during paving work, and rainwater that has permeated the surface layer cannot be drained.

また、特許第2882764号公報の図1のように、側溝ブロックの外側面に長手方向の全長に亘って導水溝を形成し、この導水溝内に透水パイプを嵌合して、表層からの雨水を透水パイプ内に浸入させ、導水溝に設けた排水孔より側溝ブロック内の排水路に流入させる方式のものが開発された。   Further, as shown in FIG. 1 of Japanese Patent No. 2888264, a water guide groove is formed on the outer surface of the side groove block over the entire length in the longitudinal direction, and a water permeable pipe is fitted into the water guide groove, so that rainwater from the surface layer is formed. Has been developed that allows water to enter the water-permeable pipe and flow into the drainage channel in the side groove block from the drainage hole provided in the water conduit.

この方式の場合は、透水パイプの使用により、砕石による導水溝の遮断は阻止されるが、透水パイプが高価なため、工事費が嵩む欠点があった。また雨水と共に表層内に流れ込んだ砂塵等が透水パイプの表面に付着して目詰まりを生じ、排水効果が損なわれることがあった。
実用新案登録第3005384号公報 特許第2882764号公報
In the case of this method, the use of the water permeable pipe prevents the water guide groove from being cut off by crushed stones, but the water permeable pipe is expensive, so there is a drawback that the construction cost increases. In addition, dust and the like flowing into the surface layer along with rainwater may adhere to the surface of the water-permeable pipe, causing clogging, and the drainage effect may be impaired.
Utility Model Registration No. 3005384 Japanese Patent No. 2888264

本発明は、透水性の表層を形成した排水性舗装道路に使用する側溝ブロックであって、透水性の表層を造るための舗装作業を効率的に行うことができる排水性舗装道路用側溝ブロックを提供することを目的としている。   The present invention is a gutter block used for a drainage pavement road having a water permeable surface layer, and a gutter block for a drainage pavement road that can efficiently perform pavement work for making a water permeable surface layer. It is intended to provide.

本発明に係る排水性舗装道路に使用する側溝ブロックは、内側の全長に亘って排水路を形成した側溝ブロックの外側面に、長手方向の全長に亘って導水溝を横設し、該導水溝の開口部を表層に使用する砕石の径より狭く、内部を広く形成し、且つ導水溝の適所に排水路に通ずる排水孔を形成したことを特徴としている。   The gutter block used for the drainage paved road according to the present invention is provided with a water guide groove extending over the entire length in the longitudinal direction on the outer surface of the side groove block in which the drainage channel is formed over the entire inner length. The opening is narrower than the diameter of the crushed stone used for the surface layer, the inside is formed widely, and the drainage hole leading to the drainage channel is formed at an appropriate position of the water conduit.

上記側溝ブロックを道路に敷設し、路床に形成した不透水性下地層上にコールタール等と砕石との混合材を積層することにより、端面が導水溝に当接する透水性の表層を形成し、排水性舗装道路を構成する。この舗装道路に降った雨水は、表層内に浸透し、導水溝内に流入して、排水孔より排水路内に流入する。   By laying the gutter block on the road and laminating a mixture of coal tar and crushed stone on the water-impermeable underlayer formed on the road floor, a water-permeable surface layer whose end face comes into contact with the water conveyance groove is formed. , Constitute drainage paved road. Rainwater that falls on the paved road penetrates into the surface layer, flows into the diversion channel, and flows into the drainage channel from the drainage hole.

排水性舗装工法において、透水性の表層に使用されている砕石は、一般に径が13mmの大きさであり、従って、上記導水溝の開口部を砕石より狭くすることにより、舗装作業中における砕石の導水溝内への侵入が防止される。そのため、表層の舗装作業が容易となる。また導水溝の内側を大きくすることにより、大量の雨水を排水路に流すことが可能でとなる。   In the drainage pavement method, the crushed stone used for the water-permeable surface layer is generally 13 mm in diameter. Therefore, by making the opening of the water guide groove narrower than the crushed stone, Intrusion into the water guide groove is prevented. Therefore, the surface pavement work becomes easy. In addition, by enlarging the inside of the water guide groove, a large amount of rainwater can be allowed to flow through the drainage channel.

本発明に係る排水性舗装道路に使用する側溝ブロックは、導水溝の開口部が表層を形成するための砕石の径より狭いため、舗装作業時における砕石の導水溝内への浸入を防止することができる。その結果、効率的な舗装作業ができる。   The gutter block used in the drainage paved road according to the present invention has an opening of the water guide groove that is narrower than the diameter of the crushed stone for forming the surface layer, and therefore prevents the crushed stone from entering the water guide groove during pavement work. Can do. As a result, efficient paving work can be performed.

しかも、高価な透水パイプを使用する必要がないので、排水性舗装道路の工事費を大幅に低減することができ、塵埃等により目詰まりを生ずることもない。また導水溝の内部を大きくすることが可能なため、路面の雨水の浸透を一層良好にすることができる。   Moreover, since it is not necessary to use an expensive water-permeable pipe, the construction cost of the drainage paved road can be greatly reduced, and clogging is not caused by dust or the like. Further, since the inside of the water guide groove can be enlarged, it is possible to further improve the penetration of rainwater on the road surface.

以下、本発明の実施形態を図1〜3を参照して詳細に説明する。図1は本発明に係る側溝ブロックの斜視図、図2は同上側溝ブロックの施工状態を示す断面図、図3は同上施工状態の要部を示す断面図である。   Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 is a perspective view of a side groove block according to the present invention, FIG. 2 is a cross-sectional view showing a construction state of the upper-side groove block, and FIG. 3 is a cross-sectional view showing a main part in the construction state.

符号1は側溝ブロックであり、内側に全長に亘って排水路3を設け、上面には雨水等を流入するためのスリット2を形成している。上記側溝ブロック1の外側面には、長手方向の全長に亘って導水溝4を横設している。この導水溝4は、開口部4aの隙間を後記する砕石の径より狭い5mm程度とし、内部4bを開口部4aより広い径で形成している。また側溝ブロック1の端面には、導水溝4と排水路3を結ぶ排水孔5を形成している。上記導水溝4の内部4bの大きさは、側溝ブロック1の強度を損なわない程度に拡大することが可能であり、水の流入量を増大することができる。   Reference numeral 1 denotes a side groove block, which is provided with a drainage channel 3 over its entire length, and has a slit 2 for inflow of rainwater and the like on its upper surface. On the outer surface of the side groove block 1, a water guide groove 4 is provided horizontally over the entire length in the longitudinal direction. In this water guide groove 4, the gap of the opening 4 a is set to about 5 mm narrower than the diameter of the crushed stone described later, and the inside 4 b is formed with a diameter wider than the opening 4 a. Further, a drainage hole 5 connecting the water guide groove 4 and the drainage channel 3 is formed on the end face of the side groove block 1. The size of the interior 4b of the water guide groove 4 can be increased to such an extent that the strength of the side groove block 1 is not impaired, and the amount of water inflow can be increased.

符号Aは排水性舗装道路であり、該舗装道路Aは路床6上に形成した高密度のアスファルト舗装による不透水性下地層7と、その上に形成した透水性の表層8とよりなり、表層8は直径が13mm程度の砕石8aをコールタール等により接合すると共に、砕石8a間に連続した空隙8bを形成している。上記表層8の側端面の下部は、側溝ブロック1の導水溝4に当接している。   Reference sign A is a drainage paved road, and the paved road A comprises a water-impermeable underlayer 7 formed by high-density asphalt pavement formed on the road floor 6 and a water-permeable surface layer 8 formed thereon. The surface layer 8 joins crushed stones 8a having a diameter of about 13 mm with coal tar or the like, and forms continuous voids 8b between the crushed stones 8a. The lower part of the side end surface of the surface layer 8 is in contact with the water guide groove 4 of the side groove block 1.

このように構成された舗装道路A上に降った雨水は、表層8内の空隙8a内に浸透した後、側溝ブロック1の導水溝4内に流入し、排水孔5より排水路2に流れ込んで排出される。   The rainwater that has fallen on the paved road A configured in this way penetrates into the gap 8 a in the surface layer 8, then flows into the water guide groove 4 of the side groove block 1, and flows into the drainage channel 2 from the drainage hole 5. Discharged.

上記導水溝4の開口部4aは、舗装時に砕石8aが導水溝4に嵌入することがないので、舗装作業が容易となる。また図3に示すように導水溝4の内部4aを広くすることにより、雨水を速やかに排水させ、路面上への水溜りの発生が防止される。しかも図3に鎖線で示すように、内部4aの底面Tを極率半径の小さい断面形状とするときは、底部に流入した塵埃等が、滞留することなく雨水と共に排水路に流し込まれる。また内部4aの形状を縦長にすることにより、内部4a内の水は導水勾配を生じ、排水路にスムーズに排水される。   Since the crushed stone 8a does not fit into the water guide groove 4 at the time of paving, the opening 4a of the water guide groove 4 facilitates paving work. Further, as shown in FIG. 3, by widening the inside 4a of the water guide groove 4, rainwater is quickly drained, and the accumulation of water on the road surface is prevented. Moreover, as shown by a chain line in FIG. 3, when the bottom surface T of the interior 4a has a cross-sectional shape with a small radius of curvature, dust or the like flowing into the bottom portion flows into the drainage channel together with rainwater without staying. Moreover, by making the shape of the inside 4a vertically long, the water in the inside 4a creates a water guiding gradient and is smoothly drained into the drainage channel.
