Description

  The present invention relates to a road that alleviates the adverse effects of high temperatures in urban areas due to the heat island phenomenon caused by paving concrete, asphalt, etc., and concentrated heavy rain that occurs in a short time.

  As urban roads become paved, the soil is covered with concrete, asphalt, etc., and the cooling effect due to evaporation of moisture in the soil is reduced, which has contributed to the heat island phenomenon. In order to solve this problem, the water-permeable road shown in Patent Document 1 has been proposed. It is well known that it has been accepted by the world and has been widely introduced.

  However, this permeable road is an effective road structure for mitigating the heat island phenomenon, but permeable asphalt and permeable concrete of pavement materials are 3 to 4 times more expensive than general non-permeable pavement. In addition, there is a problem that the wear resistance is inferior.

  Therefore, the present invention can be expected to have the same effect as that of the current permeable paved road, even if it is a normal non-permeable asphalt pavement or concrete paved road, and alleviates the adverse effects of concentrated heavy rain that occurs in a short time. The challenge is to provide roads.

  The present invention has been made to solve the above problems, and the invention according to claim 1 is a road characterized in that a water-permeable side groove is provided continuously or intermittently along a side edge. is there.

  The invention described in claim 2 is a road characterized in that the road surface has a downward slope in the center direction of the road, and a water permeable groove is provided continuously or intermittently in a recess formed in the center.

  The invention described in claim 3 is a road characterized in that a perforated water-permeable pipe is planted at an arbitrary position in the row of the water-permeable side grooves or the water-permeable grooves. As a perforated water-permeable pipe, a perforated PVC pipe is preferable because it is lightweight and easy to construct and can be provided at low cost. In addition, when the magnitude | size of a hole is not suitable for an installation site, it is good to coat | cover a water-permeable sheet on the outer side.

  The invention described in claim 4 is a road characterized in that a rainwater storage / permeable basin having an upper portion made of a water permeable material is provided at an arbitrary position of the water permeable side groove or the row of water permeable grooves.

  The invention according to claim 5 is an L-shaped groove in which a through hole is provided on the roadway side, and a grating is fixed or detachably provided on the upper part.

  According to the first aspect of the present invention, when rainwater flows into a gutter provided continuously or intermittently along the side edge, and then penetrates and drains into the soil below the paved road surface, the temperature rises. At the same time as cooling the paved road surface, the water staying in the soil evaporates through the water-permeable side grooves and has the effect of mitigating the urban heat island.

  According to the invention of claim 2, rainwater flows on the road in the direction of the center, flows into a water permeable groove provided continuously or intermittently in the center, and permeates and drains into the soil. When the temperature rises, the pavement surface is cooled, and at the same time, the water staying in the soil evaporates through the water-permeable grooves and has the effect of mitigating the urban heat island.

  According to the third aspect of the present invention, the rainwater drainage and the amount of permeation into the soil are increased to contribute to the elimination of the heat island, and also to the effect of mitigating floods during torrential rain.

  According to the fourth aspect of the present invention, when a part of the inflowing rainwater is permeated and drained into the soil, the remaining part is stored and the road surface is converted into a heat island, the same cooling effect as that when water is sprayed is obtained, and the heat island is reduced. There is an effect to contribute to.

  According to the fifth aspect of the present invention, a part of rainwater flowing from the road (roadway) is drained and infiltrated into the soil through the grating and through holes, thereby contributing to the elimination of the heat island, and the invention of the first aspect is carried out. Construction is easier than in the case, and there is an effect of reducing the construction cost.
