Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a novel floating artificial island.

[0002]

2. Description of the Related Art Although Japan has a small land area and therefore reclaims seas or lakes to create new islands or land, it requires a huge amount of buried materials, such as mountain soil, and therefore the environment It will worsen and will have a great adverse effect on marine life. Further, such landfill work requires a great deal of labor, cost and time. Furthermore, since such landfills or islands cannot be moved, it is impossible to change the direction of the airport so that when the airport is used, for example, the wind direction makes it easier for airplanes to take off and land. is there.

[0003]

DISCLOSURE OF THE INVENTION It is an object of the present invention to have an adverse effect on the environment, to be easy to manufacture, and to be movable so that its range of use can be expanded. It is to provide a floating artificial island.

[0004]

DISCLOSURE OF THE INVENTION The present invention is a floating artificial island comprising a support capable of floating in seawater or water, and an island forming body provided on the support.

Further, the present invention has an outer enclosure which surrounds the outer periphery of the artificial island with a space therebetween and can float on seawater or water, and a water surface exists between the artificial island and the outer enclosure. Characterize.

Furthermore, the present invention is characterized in that a breakwater or weir is formed around the entire circumference of the support.

Further, the present invention is characterized in that a breakwater or weir is formed over the entire circumference in the outer enclosure.

Furthermore, the present invention is one or more selected from the group consisting of a floating airport, a floating land, a floating road, a floating bridge, a floating parking lot, a floating port, a yacht harbor, a floating heliport, a golf course and a driving range. Is characterized in that.

[0009]

According to the present invention, the floating artificial island of the present invention is constructed by providing an island forming body on a support that can float in seawater or water, and therefore the floating artificial island of the present invention floats on the water surface. Therefore, it is possible to prevent adverse effects on the environment, especially marine life. Further, it can be manufactured in a factory, and if it is manufactured in advance, it can be shipped immediately if necessary, and the application is expanded. For example, in the event of an accident in which crude oil leaks into the sea due to a tanker collision, etc., it is possible to prevent the crude oil from spreading to the ocean and causing marine pollution by surrounding the outer periphery of the tanker with an annular artificial island. is there. Further, when using the floating artificial island of the present invention as an airport, the direction of the floating artificial island can be changed according to the wind direction, and the direction of the floating artificial island of the present invention can be changed so as to be convenient for takeoff and landing of an airplane.
If such a floating island is used as a residential area, the residential area can be provided at low cost.

When the floating island is used as a road, compared to the conventional construction of a bridge over the sea,
The bridge can be realized very easily, for example, the bridge between Honshu and Shikoku in Japan can be easily formed, or it is also possible to form an island with the island floating between the bridges. .

It may be partially filled, and the upper space 23 thereof may be filled with a gas such as air to have rigidity. According to such an artificial island 18, even when the tanker 23 carrying the crude oil leaks due to an accident, by providing the floating artificial island 18 according to the present invention so as to surround the tanker 23, the leakage occurs. It is possible to prevent the spread of crude oil over the ocean.

As shown in FIG. 10 as another embodiment of the present invention, the floating body artificial island 20 is constructed by providing an island forming body 25 on a support body 24 that can float on the seawater 2. Good. The island forming body 25 may be made of the same material as the supporting body 24, and such a floating body artificial island 20 may be rigid, but may be flexible.

Furthermore, in the floating artificial island shown in FIG.
An island forming body 26 is formed on the annular support 1e, and a breakwater or weir indicated by reference numeral 27 is formed thereon. Such a floating artificial island can also be implemented to surround the tanker 23 in which the accident has occurred, as in FIG. 8 described above.

FIG. 12 is a sectional view of still another embodiment of the present invention. The floating artificial island 29 can float on the seawater 2 and may be made of a metal such as rigid steel, and its inner space 30 is filled with air.
Buoyancy is generated. Such a configuration is also included in the spirit of the present invention.

[0025]

As described above, according to the present invention, a floating artificial island can be realized without adversely affecting the environment, and since such a floating artificial island can be manufactured in a factory, it is prepared and prepared in advance. By doing so, it can be moved on the sea or on the water when needed and used at a desired place, so to speak, it does not require a construction period and can be easily manufactured and sold.

Further, according to the present invention, when used as an airport, the direction of the floating artificial island of the present invention is changed according to the wind direction so that such a cross wind does not adversely affect the airplane. The direction of the floating artificial island of the present case may be changed. As a result, it is possible to easily realize a floating artificial island that is an airport that can prevent an airplane accident.

Furthermore, according to the present invention, the floating artificial island of the present invention can also be used as a road, and thus it is easy to form a road over a long distance on the sea, for example, to form a bridge between Honshu and Shikoku. It is easy to do.
Moreover, roads and residential areas can be realized by the floating artificial island of the present invention, and can be used effectively on the sea or on the water without adversely affecting the environment.

Further, according to the present invention, when an accident such as a tanker for transporting crude oil occurs, in order to prevent the crude oil from flowing out over a wide area to the ocean, the tanker that caused the accident is surrounded, By providing the floating artificial island of the present case, it is also possible to prevent environmental pollution by crude oil, and the present invention can be realized in connection with such a wide range of applications.

Further, according to the present invention, by floating the outer enclosure on the outer periphery of the artificial island and interposing the water surface between them, it is possible to prevent the artificial island from unnecessarily varying with a large amplitude due to the waves. .

Furthermore, according to the present invention, a breakwater or weir can be provided to prevent the adverse effect of waves on the artificial island.
