In order to solve the above-mentioned problems, the artificial floating island according to the present invention has the shape of the floating island body in which the bow portion floats above the water surface and the stern portion sinks below the water surface with a gentle slope. The floating island body has a pseudo-root-like projection on the side and bottom of the main body, and the bow part is on the river side and the stern part is on the downstream side so that it can be floated on the water surface of the river. It is a thing. Further, in order to solve the above problems, the accommodation facility according to the present invention,
An evacuation cove was set up on the land side of the river shore, and the above-mentioned artificial floating islands were drawn in and housed to protect from flood damage when the river was flooded or flooded. Is.

In the above and the following description, "the bow portion" means the tip portion of the main body of the floating island, which looks like the bow of the ship, and "stern portion" means the head portion of the ship. It means the rear end part of the floating island body that looks like this, and "substantially hull-shaped" is used as a term that means a shape that has a bow-like part and a stern-like part that looks like a ship. is there. Further, the “pseudo root-like projection” is used as a term meaning an artificial projection having a shape like a plant root.

[0007]

The artificial floating island of the present invention has a substantially boat-like shape, and is moored so that the bow portion is on the river side and the stern portion is on the downstream side and is floated on the water surface. However, the bow part floats on the surface of the water and separates the water so that it is not caught. In addition, since the stern part is submerged at a gentle slope below the surface of the water, shallow water with a slow water flow is formed at the water's edge, and aquatic plants, water moss and the like are easily proliferated. And by providing pseudo-root-like projections on the side and bottom surfaces, plants such as reeds can grow easily, and the roots of these plants and pseudo-root-like projections and the above-mentioned aquatic plants and water moss are used as residences for fish. It becomes easy to live and breed and breed. Furthermore, when soil etc. is placed on the top surface of this artificial floating island, the necessary water is always absorbed and supplied to the soil due to the stern part being submerged under the water surface, and the growth of plants such as various trees and flowers. Is possible. In this case, the plants growing in the stern part serve as an earth retaining function and prevent the outflow of soil and the like. By these things,
It is possible to obtain a landscape that is extremely close to nature, obtain a shape that is suitable for the natural ecology of living things, and promote the growth of plants and the habitation of fish in a state close to nature. Further, since the accommodation facility of the present invention is provided with an evacuation cove on the land side of the river shore, the artificial floating island as described above is drawn in and accommodated when the river is flooded or flooded. As a result, it is possible to protect from damage from large water, and also to protect plants and fish that inhabit the artificial floating island.
