Since the conventional air purification wall greening apparatus uses soil such as lightweight soil as the soil base, it has the following problems.
-Heavy soil base. For example, soil is wet and has a specific gravity of about 0.5.
・ Since the weight of the soil base is heavy, it is necessary to construct the structure of the air purification wall greening device firmly, which is expensive.
-Distribution of soil composition tends to be uneven in the soil itself or the entire soil layer, and unevenness in air permeability tends to occur.
・ Soil spills out from the front, which is the greening surface, so it is not suitable for indoor installation.
・ Because it is on-site construction, it takes time, labor, and cost for construction.
・ Soil base soil is reduced, so it is necessary to replenish the soil appropriately.

For example, the irrigation means 21 is a tube having one end connected to a water supply source and a plurality of holes formed in the outer periphery, and water that has oozed out from the holes is supplied from the irrigation inlet 13 of the uppermost container unit 5 to the same container. It is dripped at the plant stage growth base 1 accommodated in the part 5. The excess water in the uppermost plant growth base 1 is dropped downward from the irrigation outlet 14, and water is supplied to the second stage plant growth base 1 from above. In the same manner, water is sequentially supplied to the plant growth base 1 below.

  The portion on the front side of the partition plate 14 at the bottom of the device housing 3 receives the extra water falling from the lowermost plant growth base 1 and guides it along the width direction of the air purification wall greening device. It has become. A drainage pipe 23 extending downward is provided in the downstream part of the water guide direction of the trough 22, and the water received by the trough 22 passes through the drainage pipe 23 to a water storage tank 24 provided below the air chamber 17. Collected. By providing the trough 22 and the water storage tank 24, excess water can be collected.

In the air purification wall greening device having this configuration, a plant 30 is planted on each sponge-like or roll-like plant growth base 1, and an appropriate amount of water is supplied to each plant growth base 1 by the irrigation means 21. The plant 30 extends outward from the planting opening 12 of the container unit 5 and greens the wall surface on the front side. Moreover, since the ventilation layer 6 is provided in the back side of each plant growth base | substrate 1, and the vent hole 11 connected to the ventilation layer 6 is provided in each container part 5, by blowing with the fan 19, each plant growth base | substrate It is possible to generate a flow of air passing through 1 from the back side to the front side, or a reverse air flow. Due to this air flow, when the air passes through each plant growth base 1, contaminants in the air are adsorbed and removed, and the air is purified. Since the plant growth base 1 is in the form of a sponge or a roll, it can be made to have a uniform specification, and therefore unevenness in air permeability is unlikely to occur.
