Description

The present invention relates to a disaster prevention facility that is effective for both earthquake and flood disaster prevention.

Conventionally, as a countermeasure against earthquake disasters, shelters for earthquakes with a large load capacity installed indoors or underground have been known. Further, as a countermeasure against a tsunami disaster or a flood disaster, a floating shelter floating on the water surface is known (see, for example, Patent Document 1).

Although the shelter for earthquakes installed as a countermeasure against earthquake disasters is effective for earthquake disasters, sufficient effectiveness for flood disasters has not been considered. Similarly, floating shelters installed as countermeasures against flood disasters need to be lighter in order to float on the surface of the water, and sufficient effectiveness against earthquake disasters has not been considered.

In the event of a flood, for example, people can evacuate to a floating shelter installed as a countermeasure against flood disasters, but houses and cars on the ground will be flooded, and the houses and household goods and cars in these houses will be inundated. It will occur.
