AI Technical Summary

Benefits of technology

The invention relates to finding ways to raise the water level in a sealing dome to allow coral to grow on an island and develop land. The first aspect focuses on reducing the air pressure inside the dome to raise the water level, while the second aspect focuses on increasing the air pressure to lower the water level and expose underwater rock. This allows for the development of land through the workings of nature.

Problems solved by technology

In small islands such as the Okinotori Islands, for example, coastlines are disappearing due to coastal erosion and rising sea level caused by global warming, and these islands are at risk of going underwater.

Embodiment Construction

[0026]First, terms that are used in the present specification will be defined. A coral reef is a geological formation created by clusters of reef-building coral, the coral itself being a tiny organism called a polyp. Polyps attach to the sea floor and split up, and once grown are called coral. Over time, a coral will grow and attach to other corals, forming a coral reef. Coral skeletons are made of a calcareous substance (calcium carbonate). The mineral of coral skeletons is aragonite, which has a specific gravity of approximately 2.9, a Mohs hardness of approximately 4, and a compressive strength of approximately 12.4 Mpa (126.48 kgf / cm2).

Abstract

A method for developing a piece of land that is in danger of disappearing due to its small size above a seawater level, including covering the piece of land with a sealing dome larger than the piece of land such that a space is created between the piece of land and the sealing dome and such that a lower edge of the sealing dome is in the sea, securing the sealing dome, while leaving a gap between the lower edge of the sealing dome and a sea bottom, reducing the air pressure inside the sealing dome such that the seawater level inside the sealing dome rises above at least a part of the piece of land to allow coral to naturally grow on the at least the part of the piece of land, and returning the air pressure inside the sealing dome to the same air pressure as outside so that the naturally grown coral on the part of the piece of land becomes calcified coral by being exposure to air, and the calcified coral remains as a developed portion of the piece of land.

Description

TECHNICAL FIELD[0001]The present invention relates to a method for developing land such as an island.BACKGROUND ART[0002]In small islands such as the Okinotori Islands, for example, coastlines are disappearing due to coastal erosion and rising sea level caused by global warming, and these islands are at risk of going underwater.[0003]According to the IPCC Fourth Assessment Report Working Group I Chapter 5, the global average sea level is estimated to have risen 3.1±0.7 mm / year from 1993 to 2003, and it is reported that by the mid-2090s the global average sea level will have risen 0.22-0.44 m compared to 1990 levels, which is an annual rise of approximately 4 mm, for example.[0004]To deal with this, measures for solving the problem of coastal erosion have been taken, which include placing a plurality of concrete blocks on the sea bottom near the coast so as to absorb the force of approaching waves.[0005]In Patent Document 1, for example, a method of building a natural rock block that...
