Abstract

PURPOSE:To provide a water retaining function so as to suppress a heat island phenomenon. CONSTITUTION:A drain material layer 3, an earth layer 4 and a porous artificial lawn sheet 5 respectively of specified thickness are laminated in this order on a concrete layer 1. Rainwater or the like thereby permeates the earth layer 4 through the holes of the artificial lawn sheet 5, and water is retained therein by the water retaining action. The water in the earth layer 4 is gradually transpired through the holes of the artificial lawn sheet 5. The texture similar to natural lawn can be thereby imparted to the artificial lawn so as to inhibit a heat island phenomenon at a place where the artificial lawn is laid.

2. Description of the Related Art Conventionally, as a method for constructing a green space on a stadium, a park, a green space on a rooftop floor, etc., a method of planting natural grass such as natural grass, or artificial grass such as artificial grass in place of natural grass There is a way to place it. Although natural grass has the advantage that artificial grass does not have the texture that natural materials have, it not only has uneven vegetation status depending on the season or cultivation site and grower, but also the vegetation status at the time of laying is uniform. Even after installation, it is necessary to sprinkle water appropriately to prevent it from dying while removing excess water.
Moreover, maintenance is troublesome due to the risk of disease, and it is easy to be damaged if the green space is open or in the stadium, and it takes a long time to recover when damaged. There's a problem.

However, natural grass has no problem because the grass itself and the soil have a water-retaining function, but it is necessary to construct the concrete base 1 for laying the artificial grass. In addition to the fact that artificial turf itself does not have a water retaining function, it also promotes the heat island phenomenon (a phenomenon in which islands that do not drop in temperature even at night) that are currently a problem in urban areas such as central Tokyo. become.

In order to avoid such a phenomenon, it is conceivable to install a water tank on the concrete base 1 and evaporate the water in the water storage layer from the artificial grass sheet, but compared with the case where natural grass is arranged. There is a problem that the water evaporates remarkably and a texture similar to natural grass cannot be obtained.

When rainfall or water sprinkling is insufficient, the water in the drainage material layer 3 is supplied to the soil layer 4 by a capillary action so that a necessary amount of water (varies depending on the water retention state of the soil material layer 4 or the drainage material layer 3) is supplied. It In this way, a place where artificial grass is laid by supplying a proper amount of water to the soil layer 4 at all times, even if there is insufficient or no rainfall, and if the sprinkling time is not well managed. The heat island phenomenon can be reliably prevented.
