BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an artificial ground for vegetation provided for the purpose of greening a roof of a building, a courtyard or the like.

[0002]

2. Description of the Related Art Conventionally, a vegetation soil layer is formed on a foundation (hereinafter, simply referred to as a "base") such as a concrete slab of a building for the purpose of greening a roof or a courtyard of the building. Trees and flowers are planted in this vegetation soil layer. By the way, when a vegetation soil layer is formed on a base, water supply from the base is generally not expected, so frequent irrigation must be performed especially during high-temperature drying in the summer, and it takes time and effort to manage irrigation. There was a problem. To cope with this, a method of laying a sprinkler pipe on the ground or in the vegetation soil layer and spraying water from this sprinkler pipe has been put into practical use. Even if water is sprayed, water cannot be uniformly distributed to the vegetation soil layer, and it is difficult to maintain the vegetation soil layer in a state suitable for plant growth, and a large amount of water is partially generated. If supplied, not only against plants,
There is also a possibility that the concrete slab of the building constituting the base may be adversely affected.

SUMMARY OF THE INVENTION According to the present invention, a vegetation soil layer formed on a base can be easily maintained in a state suitable for plant growth, the construction cost of equipment is low, and
An object of the present invention is to provide an artificial ground for vegetation that does not adversely affect a concrete slab or the like of a building constituting a base.

[0004]

In order to achieve the above object, an artificial vegetation ground according to the present invention comprises an artificial vegetation ground in which a vegetation soil layer is formed on a base, with a gap provided on the base. A plurality of tray-shaped pallets arranged in parallel are filled with a water-permeable material, and a water supply pipe for supplying water to the pallets and a drain pipe for discharging water from the pallets are provided.
A vegetation soil layer is formed on the entire surface of the base including the upper surface of the pallet.

By supplying water from a water supply pipe to a pallet filled with a permeable material, an appropriate amount of water is stored over the entire surface of the pallet, and is uniformly distributed on a vegetation soil layer formed on the upper surface of the pallet. Water can be distributed and excess water in the pallets can be drained from drains.

In this case, a plurality of pallets are arranged side by side with a difference in height, a water supply pipe is connected to the pallet provided at the highest position, and an overflow pipe of the pallet provided at the highest position is provided at a lower position. Can be connected to a pallet provided in the pallet.

Thus, the water supplied to the pallet provided at the highest position is sequentially supplied to the pallets provided at a lower position through the overflow pipe provided at the pallet provided at the highest position. Thereby, an appropriate amount of water can be stored over the entire surface of each pallet.

In addition, a granular material can be used as the water-permeable material to be filled in the pallet, and a water-permeable sheet can be provided between the water-permeable material and the vegetation soil layer.

[0009] This prevents the soil constituting the vegetation soil layer from entering the water-permeable pores of the permeable material, and the water supplied from the water supply pipe is formed on the upper surface of the pallet for a long period of time. It can be spread over the entire surface of the pallet without being affected by layers.
