  However, in the above prior art, since there is no specific description about the irrigation means, it is common to think that it is due to watering from above, but places where people and things frequently come and go, For example, in the case of a parking lot, water is splashed on the parked car and water cannot be sprinkled under it, and as a specific method, automatic sprinkling and handing with a sprinkler will be used, but both will spray evenly throughout Because it is necessary to sprinkle more than the necessary amount, the management cost cost is extra, and the former method requires equipment and equipment maintenance management cost, but labor cost is unnecessary, There is a problem that has to be solved, such as the watering equipment is not necessary in the latter case, but there is a disadvantage that increases the labor cost, in the case of the latter, there is a disadvantage that it takes people in the planting area when watering on a regular basis

  The present invention is based on the above prior art, in view of problems such as being unable to cope with places where the situation changes irregularly by sprinkling from above, a diffusion / water retention sheet laid on the surface of the planting area, A water-retaining layer formed by leveling earth and sand on the surface on which the diffusion / water-retaining sheet is laid, and a perforated bottom wall and regularly filled on the water-retaining layer. By having a plurality of planting units in which plants are planted on the soil and irrigation pipes buried below the plants, water can be supplied below the plants, and only the required amount can be supplied. In this way, the water absorbed by the diffusion / water retention sheet is uniformly distributed throughout the water, and the above-mentioned problems are solved by reducing the cost of equipment and equipment maintenance.

In short, the present invention has a diffusion / water retention sheet laid on the surface of the planting region, and a water retention layer formed by spreading soil and sand on the surface where the diffusion / water retention sheet is laid. ,
Since a thin material can absorb and retain a sufficient amount of water, the thickness of the entire planting structure can be suppressed, and rainwater that has permeated through the soil and water retention layer, which will be described later, is absorbed and retained. It has a perforated bottom wall that is regularly arranged on a water retention layer formed by spreading earth and sand on the surface on which a diffusion / water retention sheet is laid. In addition, since it has a plurality of planting units in which plants are planted on the filled soil and irrigation pipes buried below the plants, water can be supplied below the plants. And since it is absorbed and diffused by the diffusion / water retention sheet and spreads throughout the diffusion / water retention sheet, even if there are people or objects in the planting area, these do not get water, and the entire planting area The required amount of water can be supplied evenly over the entire area.
In addition, diffusion and water retention sheets and irrigation pipes and their installation work, as well as earth and sand for the water retention layer and the formation of the water retention layer are required. Can be reduced.
Therefore, even if the planting area is paved with asphalt or concrete, for example, when greening the pavement area as a countermeasure for the heat island phenomenon, the removal work of the pavement material at the time of construction is unnecessary and no waste material is generated The construction cost can be reduced.

  Since the irrigation pipe is embedded in the water retention layer or embedded in the soil, the above structure can be implemented specifically and efficiently. Especially in the former case, the irrigation pipe is located in the immediate vicinity of the diffusion / water retention sheet. Therefore, it is possible to absorb and retain water immediately after water supply to the diffusion / water retention sheet, and when replacing the planting laying unit, the irrigation pipe does not get in the way and the replacement work can be performed easily. is there.
