Abstract

PURPOSE:To enhance the strength and simplify assembly and disassembly by forming a complete of landing strip through combination of a number of blocks as a fundamental structure in two rows, arranging two such completes parallelly with a certain distance between, and thereby constituting a floating artificial island. CONSTITUTION:Underwater members, on-sea members, and culumnar members to couple them together are assembled into a block 1 as a fundamental structure having a square oversurface with an edge of several tens of meters long. A number of such blocks 1 are set together into a row to constitute a complete 2 of airport landing strip, and two of such completes 2 are arranged parallelly with a certain distance between to constitute a floating artificial island. To hold this artificial island in a specified position, the blocks 1 situated at the four corners are provided with a side thruster D. This artificial island is equipped with a plurality of marine culture zones 4-6 in its central part, a sightseeing berth 7 and a sporting berth 8 on the two sides in longitudinal direction, and a metal sail 9 and houses at the joint parts 3A, 3B.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a floating artificial island that can be used for multiple purposes.

Conventional technology Up until now, floating artificial islands have been constructed to be moored in shallow waters and have been used for a single purpose: to expel pollution from offshore airfields, nuclear power plants, chemical factories, etc. into the sea. .

However, such floating artificial islands are harmful to the sea, and their construction is difficult due to concerns not only with respect to nature conservation but also with the fishing industry.

Problems to be Solved by the Invention In order to solve the problems associated with conventional floating artificial islands, the present invention aims to provide a floating artificial island that can obtain synergistic effects as a comprehensive marine development base. purpose.

A means to solve the problem, that is, a floating artificial island according to the present invention is provided with a solid body serving as the basic unit structure of the floating island on an underwater member that maintains buoyancy and stability, and by assembling two rows of the solid body together. Two of these assemblies are arranged to face each other in parallel with a gap between them, and both assemblies are connected and fixed together in a ladder shape through the solid body, and a direction maintaining device is provided in the ladder-like connection part. A configuration in which side thrusters are installed on solid underwater members located at the four corners (tips) of the ladder shape in order to always align the direction of the runway (of the airport) with the direction of JJI and to keep the floating island in place. It is characterized by

Operation Therefore, according to the above structure of the present invention, a floating foundation is created in the sea using underwater members that maintain buoyancy and stability, and pillars are extended from this to support a structure on the sea surface, and this one structure is used as the basic unit structure of a floating island. By assembling two rows together, we can safely and reliably separate and replace damaged or aging basic unit structures at sea, and by placing two of these assemblies in parallel and facing each other with an interval between them. They are connected together in a ladder shape through unit structures, and the 0-shaped sea area surrounded by the structures is used as an aquaculture zone for fish, etc., and the mouth-shaped sections at both ends are used as ports and marine sports zones. A runway for aircraft takeoff and landing and a floating city will be built on the island, and the island's position and orientation will be controlled using metal sails and side thrusters.

Example The present invention will be explained below based on embodiments shown in the drawings.

This embodiment is a multi-purpose floating artificial island, and the basic unit structure shown in FIG. is a planar shape of 100 x 100 square meters (or 50 x 50). The solid bodies 1 are arranged in two rows to form an assembly 2 that constitutes an airport runway, and two of these assemblies 2 are arranged in parallel and facing each other with an interval between them, as shown in FIG. In this embodiment, two rows of two parts 3A and two rows of four parts 3B are used as connecting parts.

The total length is 800 meters or more, 2000 meters or 4
000 meters, width of 400 meters or more, height from the water surface of 20 meters or more, and depth of the underwater members in the lateral direction below the water surface of 20 meters or more, thereby reducing vibration from all directions due to waves to zero.

In order to maintain the fixed position of the floating artificial island, Zydo thrusters D are attached to solid underwater members A located at the four corners (each tip) of the ladder-shaped structure.

As can be seen from Figure 2, aquaculture zones 4, 5, and 6 are formed in the center. A water/underwater sightseeing berth 7 and a marine sports berth 8 are formed on both sides in the longitudinal direction.The former is used for sightseeing boats, hydrofoils, underwater sightseeing boats, etc., while the latter is used for yachts, motor boats, windsurfing, etc. Water Scooter 1 Used by water skis, small submersibles, underwater scooters, etc. As a marine tourism zone,
FM facilities such as an underwater hotel, restaurant, theater, music hall, and fishing center will also be set up.

In addition, two metal sails 9, which are direction maintaining devices, are attached to the connecting portion 3A.
The connecting section 3B includes a marine school, a marine museum, an aquarium, a marine art salon, a general management system, an operation command system, etc.

Maintenance and management of floating artificial islands is much more difficult than on land, and requires regular patrols on and under water. These management and operation mechanisms are quite complex and wide-ranging, and in order to protect the life safety of adults living on the island and users from outside, a management and operation system like the one shown in Figure 4 is required.

Furthermore, if we consider the useful life of a floating artificial island in the same way as a super-large steel ship, it will require partial repair every 10 to 20 years, and in order to facilitate this partial repair, the solid bodies 1 are combined in two rows. This is because if the intermediate solid is separated in one row, the square portions may separate or excessive force may be applied to some parts, impairing the safety and efficiency of the work.

In addition, when removing, repairing, or replacing Solid 1, those that are trapped inside #f should be immersed in underwater member A (floating body) by water injection, pulled out to the outside, and then brought to the surface by drainage. .

Furthermore, unlike super-large ships, floating artificial islands do not have docks where they can be docked for repairs, so it is necessary to construct a repair shop and staff on the island so that repairs to a certain degree can be carried out on one's own.

In addition, energy development systems such as solar angle power generation systems, wind power generation systems, seawater temperature difference power generation systems, and ocean current power generation systems are also required in order to be self-sufficient in light and heat sources and power sources within the floating artificial island, as well as security, disaster prevention, and pollution prevention systems. Comprehensive ocean development is required.

Effects of the Invention As can be seen from the above explanation, according to the configuration of the present invention, a floating island as a basic unit is constructed using a semi-sub method in which the solid body serving as a basic unit structure is a floating body construction method, and two rows of solid bodies are assembled together. At the same time, since the entire floating island is assembled and connected in the form of a ladder, the structural strength is increased, making disassembly, assembly, repair inspection, etc. easy and reliable. It can be used as aquaculture facilities, and by installing highly polluting airfields and chemical systems on floating artificial islands as marine comprehensive development bases, it will be made pollution-free, and difficult problems on land will be solved. Barriers such as fish industry compensation are also not an issue.
