Abstract

To solve the problem that it is difficult for residents who cannot live in a house due to an earthquake, a tsunami, a fire, or the like to secure a lodging place for a restoration worker because the residents cannot go to a house with electricity and water while being safe against an aftershock and a tsunami and protecting privacy.SOLUTION: A wooden artificial island is floated on the sea adjacent to the land, a plurality of dwellings are installed on the wooden artificial island, and the wooden artificial island is fixed by setting a concrete guide on the sea adjacent to the land, passing a log connected to the wooden artificial island through the concrete guide, and stopping the wooden artificial island with two wooden stoppers so that the wooden artificial island does not move in the horizontal direction (left, right, front, and back) but can move in the vertical direction to cope with the ebb and flow of the tide.SELECTED DRAWING: Figure 1

Description

[Technical Field]

[0001] The present invention relates to a technology for constructing floating wooden artificial islands on the sea or lake and building houses on them. [Background technology]

[0002] Traditionally, life on the ocean typically meant living on a ship. When a large city was devastated by a major earthquake, tsunami, or fire, the first thing that needed to be done was to remove the rubble, and then houses needed to be repaired or rebuilt, including earthquake countermeasures, so recovery inevitably took a long time. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-147573 Summary of the Invention [Problem to be solved by the invention]

[0004] Residents who have lost their homes due to earthquakes, tsunamis, or fires are unable to live in homes that are safe from aftershocks and tsunamis, have privacy, and have electricity and running water, making it difficult to secure accommodation for recovery workers. In addition, in response to predicted disasters such as the Nankai Trough earthquake, there is a need for preventative housing that is resistant to earthquakes and tsunamis. [Means for solving the problem]

[0005] A wooden artificial island is floated on the ocean adjacent to the land, and multiple dwellings are installed on it, and the wooden artificial island is fixed by setting a concrete guide on the ocean adjacent to the land, and passing logs connected to the wooden artificial island through the concrete guide and fastening it with two wooden stoppers, so that it cannot move horizontally (left and right, front and back), but can move up and down in response to the ebb and flow of the tides. A concrete slope is set on the land side, a wooden walkway is set to connect the wooden artificial island with the concrete slope, and rubber tires are set on the wooden walkway so as to accommodate the up and down movement of the wooden artificial island due to the ebb and flow of the tides. [Effects of the Invention]

[0006] People can live in offshore housing that is safe from earthquakes and tsunamis. Also, by moving to offshore housing, their current homes will no longer be needed, and the land can be converted into a new town, for example, by building a Utopia building on the site, creating a "society where everyone can be happy." [Brief explanation of the drawings]

[0007] [Figure 1] This shows the gist of the present invention. [Figure 2] The main points of the present invention and related wooden artificial islands are shown below. DETAILED DESCRIPTION OF THE INVENTION

[0008] A wooden artificial island is floated on the ocean adjacent to the land, and several residences are installed on it. The wooden artificial island is fixed in place by setting up a concrete guide in the ocean adjacent to the land, and passing a log connected to the wooden artificial island through the concrete guide and fastening it with two wooden stoppers, so that it cannot move horizontally (left and right, front and back), but can move up and down in response to the ebb and flow of the tides. A concrete slope is set on the land side, a wooden walkway is set to connect the wooden artificial island with the concrete slope, and rubber tires are set on the wooden walkway so as to accommodate the up and down movement of the wooden artificial island due to the ebb and flow of the tides.

[0009] In Figure 1, a wooden artificial island is floated in the ocean adjacent to the land, and multiple residences are installed on it. The wooden artificial island is fixed in place by setting up a concrete guide in the ocean adjacent to the land, and passing logs connected to the wooden artificial island through the concrete guide and fastening it with two wooden stoppers, so that it cannot move horizontally (left and right, front and back), but can move up and down in response to the ebb and flow of the tides. A concrete slope is set on the land side, a wooden walkway is set to connect the wooden artificial island with the concrete slope, and rubber tires are set on the wooden walkway so as to accommodate the up and down movement of the wooden artificial island due to the ebb and flow of the tides. Offshore housing (reconstruction housing) has the following seven benefits: · It is as safe as Noah's Ark from tsunamis and aftershocks. Fast delivery time (3 months): Wooden artificial islands and houses in other coastal municipalities They are made, transported by ship, lowered by crane, and then fitted and glued together using a spigot setting. Low cost (less than 1 / 3 of the cost of land): No land acquisition or land preparation required. No earthquake countermeasures or foundation work are required, and no road traffic control is required. A supermarket, hospital and city hall will be set up on board, and the ship will make rounds. It will make life much easier. (Even after the city has fully recovered, boats will still be useful.) · Recovery workers and volunteers can also live there, accelerating the recovery process. Offshore restoration homes can be lived in for a long time (thousands of years) and are inexpensive. Because it is cheap, convenient, and offers ample living space, the number of residents is increasing. We can build a society where everyone can be happy. (Search for "wooden artificial island" and (See "A Society Where Everyone Can Be Happy" on the Garden Field website.) Each house is a single-story wooden house with exterior dimensions of 10m x 10m, and ceilings of 5-6m, allowing for a more spacious feel. (120m square, 100 houses of 10m square, 4m corridors, 4 units of 4 houses, totaling 20m square.) Note: The front door is supported by a gasket (with a little play), and when submerged, the water pressure presses the door firmly against the gasket, sealing it.The windows are also set on the upper side, so that in the unlikely event of a large ship colliding with the unit and causing it to slide off (be thrown into the sea), it will float on the water, just like Noah's Ark, protecting the family. Rather than building it on site, we think it would be better to build the entire structure in possible municipalities across the country, tow it by boat, and then build concrete guides, concrete slopes, and a wooden walkway on site to accommodate the tides, as well as prepare the wiring and piping for electricity and water (sewage), and then dock it. Figure 2 shows an overview of the wooden artificial island. A 12m square angle is assembled from wood to form the basic unit of the wooden artificial island. In Figure 2, there are six basic units of the wooden artificial island, but by adding and expanding the basic units in the direction of the arrow, it is possible to create a large artificial island of several kilometers square or more. Holes are drilled in the sides of the angles of the basic unit of the wooden artificial island, and after positioning with wooden rivets, the angles are bonded together to expand the island. [Industrial Applicability]

[0010] People can live in offshore housing that is safe from earthquakes and tsunamis. Also, by moving to offshore housing, their current homes will no longer be needed, and the land can be converted into a new town, for example, by building a Utopia building on the site, creating a "society where everyone can be happy."

Claims

[Claim 1] A wooden artificial island is floated in the ocean adjacent to land, and multiple dwellings are installed on it. The wooden artificial island is fixed in place by installing a concrete guide in the ocean adjacent to land, and the concrete guide is fastened with two wooden stoppers through logs connected to the wooden artificial island, so that the island cannot move horizontally (left and right, front and back), but can move up and down in response to the ebb and flow of the tides. An offshore housing unit is installed with a concrete slope on the land side and a wooden walkway connecting the wooden artificial island and the concrete slope, and rubber tires are installed on the wooden walkway to accommodate the up and down movement of the wooden artificial island due to the ebb and flow of the tides.
