Description

本発明は、ヒートアイランド現象の軽減技術に属する。 The present invention belongs to a technique for reducing the heat island phenomenon.

近年、都市空間がコンクリートやアスファルト等で形成された結果、都市部の気温が郊外より高くなるヒートアイランド現象が顕著になっている。
その抑制手段として、歩道、自転車道、広場などにおいて舗装材として保水性ブロックや透水性ブロックを敷き設する試みがなされている。
これは、路床上に路盤材として耐久性のあるクラッシュランをよく締め固め、その上にサンドクッション材を敷き、さらにその上に舗装材としての保水性ブロックや透水性ブロックを敷き設することで、保水性ブロックやサンドクッション材の保有する水分の気化熱を利用して舗装材の保有熱を減少させようとするものである。 In recent years, as a result of the urban space being formed of concrete, asphalt, etc., the heat island phenomenon has become prominent, where the temperature in urban areas is higher than in the suburbs.
As a restraining means, attempts have been made to lay water retaining blocks and water permeable blocks as paving materials on sidewalks, bicycle paths, and open spaces.
This is done by compacting a durable crash run as a roadbed material on the roadbed, laying a sand cushion material on it, and laying a water retaining block or permeable block as a paving material on it. It is intended to reduce the heat retained by the pavement material by utilizing the heat of vaporization of the water retained by the water retaining block and the sand cushion material.

しかしながら、上記方法はサンドクッション材の天然砂、クラッシャランはそれ自体保水性が乏しいため、地下水位が低い場合などサンドクッションやクラッシャランを介する毛管現象が働かないため、舗装材として透水性舗装を施した場合、水分が全く上昇してこないため冷却作用がなくなってしまう。また、保水性ブロックを使用した場合でも、水分の補給がなされないため、ブロック自体が保有する水の蒸発による冷却作用のみとなり、冷却作用が持続しない。
特開2002-155502 However, the sand sand cushion material, crusher orchid itself has poor water retention, so the capillarity via the sand cushion or crusher run does not work when the groundwater level is low. In this case, the water does not rise at all, and the cooling action is lost. Further, even when a water retaining block is used, since water is not replenished, only the cooling action by evaporation of water held by the block itself is obtained, and the cooling action is not continued.
JP2002-155502

本発明は、地下水位に関係なく毛管現象に基づく雨水の蒸散作用による冷却作用が持続する透水性路面の提案にある。 This invention exists in the proposal of the water-permeable road surface with which the cooling effect | action by the transpiration | evaporation effect | action of the rainwater based on a capillary phenomenon continues irrespective of a groundwater level.

本発明は、区画された透水部と踏み圧部を有し、あるいは形成する枠体ブロックを敷き設した透水性の路面とその下部に設けられた雨水貯留部からなり、透水性の路面と雨水貯留部との間には透水性路面に降った雨水を雨水貯留部に導入させかつ雨水貯留部の雨水を透水性路面に導出する浸透層が設けられ、雨水貯留部には透水性路面を支持できるよう隙間を有する支持体が充填され、雨水貯留部に溜まった過剰の雨水は前記浸透層を介して流出可能とされたことを特徴とするヒートアイランド現象軽減路面である。 The present invention comprises a water permeable road surface having a partitioned water permeable portion and a stepping pressure portion, or a laid water block provided with a frame block to be formed, and a rain water storage portion provided therebelow. Between the reservoir and the reservoir, there is an infiltration layer that introduces rainwater that has fallen on the permeable road surface into the rainwater reservoir and leads the rainwater from the rainwater reservoir to the permeable road surface. The rainwater reservoir supports the permeable road surface. The heat island phenomenon reducing road surface is characterized in that a support body having a gap is filled so that excess rainwater collected in the rainwater storage portion can flow out through the permeation layer.

本発明は、透水部と踏み圧部からなるブロックを敷き設した路面下に雨水の貯留空間を設け路面との間に浸透層を設けているため、地下水位が低い場所においても雨水貯留部に溜まった雨水が毛管減少で路面まで上昇するため透水部より蒸発するので冷却作用が持続する。
さらに路面が透水性部を有しているため雨水が路面下の貯留空間に継続的に貯留される。 In the present invention, a rainwater storage space is provided under the road surface laid with a block composed of a water permeable portion and a treading pressure portion, and an infiltration layer is provided between the road surface. Since the accumulated rainwater rises to the road surface due to the capillary reduction, it evaporates from the water permeable part, so the cooling action continues.
Furthermore, since the road surface has a water permeable portion, rainwater is continuously stored in a storage space below the road surface.

以下本発明を図により詳細に説明する。
図1から図３に示すように、本路面の最上部は、透水部と踏み圧部に区画されており、次層が浸透層であり、最下層には雨水貯留部を設けている。 Hereinafter, the present invention will be described in detail with reference to the drawings.
As shown in FIGS. 1 to 3, the uppermost part of the main road surface is divided into a water permeable part and a stepping pressure part, the next layer is a permeation layer, and the rainwater storage part is provided in the lowermost layer.

路面の最上部は透水部と踏み圧部用に区画された枠体ブロックを敷き設し、踏み圧部に別途設けた敷き石等をはめ込みあるいはコンクリートを流し込んで踏み圧部とする。枠体ブロックの例は、図4にされている。図4ａに示すブロックは、踏み圧部と透水部用とに分かれているが、踏み圧部は別途コンクリートを流し込むあるいは所定の形状に形成された石、コンクリート、レンガ、木板が嵌め込まれるようになっている。透水部はそのままブロックに設けられた孔部である。必要に応じて砂利砕石等を孔部に充填することができる。 The uppermost part of the road surface is laid with a frame block partitioned for a water permeable part and a stepping pressure part, and a paving stone or the like separately provided in the stepping pressure part is fitted or concrete is poured into the stepping pressure part. An example of the frame block is shown in FIG. The block shown in FIG. 4a is divided into a treading pressure part and a water permeable part, but the treading pressure part pours concrete separately, or stones, concrete, bricks, and wooden boards formed in a predetermined shape are fitted. ing. The water permeable part is a hole provided in the block as it is. If necessary, gravel crushed stone or the like can be filled in the hole.

図4ｂに示すブロックは、踏み圧部が格子状の壁を形成し、壁にかこまた孔部が透水部を形成する。孔部には適宜砕石、砂利あるいは土を充填することで、格子部と透水部が合わせて踏み圧部となる。水は上記孔部に充填された砕石などの隙間を介して下部に浸透する。 In the block shown in FIG. 4b, the treading pressure part forms a grid-like wall, and the wall and the hole part form a water-permeable part. By appropriately filling the hole with crushed stone, gravel or earth, the lattice portion and the water permeable portion are combined to form a stepping pressure portion. Water permeates into the lower part through a gap such as crushed stone filled in the hole.

図4ｃに示すブロックは、踏み圧部がブロックの中心を占め、その周囲に透水部を設けている。踏み圧部には別途石、コンクリート、レンガ、木板が嵌め込まれるようになっている。透水部には適宜砕石、砂利あるいは土を充填することができる。 In the block shown in FIG. 4c, the treading pressure part occupies the center of the block, and a water permeable part is provided around it. Stones, concrete, bricks, and wooden boards are fitted in the foot pressure part. The water permeable part can be appropriately filled with crushed stone, gravel or soil.

浸透部は路面に降った雨水が、下層に設けた雨水貯留部に浸透し、あるいは雨水貯留部に溜まった雨水が毛管減少で路面まで上昇できるよう、砂利、砕石、砂などを単独あるいは混合して形成される。必要に応じてパーライト、バキュームライト、ロックウール、ガラスウールなどを単独あるいは混合することができる。 In the infiltration section, rainwater falling on the road surface penetrates into the rainwater storage section provided in the lower layer, or gravel, crushed stone, sand, etc. are mixed alone or mixed so that the rainwater collected in the rainwater storage section can rise to the road surface by capillary reduction. Formed. Perlite, vacuum light, rock wool, glass wool or the like can be used alone or in combination as required.

雨水貯留部は図1、図2にしめすような容器、図3に示すような遮水性のシートを敷き設しあるいは粘土層を形成してもよい。
容器内あるいはシート上には路面を支持できるよう、路面にかかる踏み圧に応じて砕石あるいは雨水貯留浸透槽用に用いられる雨水貯留材と称するプラスチック製のブロック類などを充填しておく。なお、雨水貯留部から溢れた過剰の雨水は、浸透槽を介してあるいは雨水貯流部と雨水貯流部との間を介し排出されるようにしておくのが好ましい。雨水貯留部が容器であるならその間にも適宜砕石などを充填しあるいはシートならばシートとシートの間を空けることでもよい。 The rainwater storage part may be a container as shown in FIGS. 1 and 2, a water-impervious sheet as shown in FIG. 3, or a clay layer.
In order to support the road surface in the container or on the sheet, plastic blocks or the like called storm water storage material used for crushed stones or rainwater storage and penetration tanks are filled according to the stepping pressure applied to the road surface. In addition, it is preferable that the excessive rainwater overflowing from the rainwater storage part is discharged through the permeation tank or between the rainwater storage part and the rainwater storage part. If the rainwater storage unit is a container, crushed stones may be filled between the rainwater storage unit or a sheet may be provided between the sheets.
