Claims

[Scope of utility model registration request]

In an earthquake-proof water tank for a floating body, in which a tank created by digging the ground is filled with water and a floating body is floated thereon, a horizontal flat plate-like temporary structure is installed at an appropriate level of the tank, the peripheral part of which is supported on the bottom of the tank via a plurality of springs. a bottom plate; a horizontal flat plate-like seismic plate vertically installed on the lower surface of the temporary bottom plate via a plurality of springs attached at appropriate intervals vertically and horizontally;
A seismic isolation water tank for a floating body, comprising a watertight membrane whose upper edge is watertightly fixed to the lower surface of the temporary bottom plate, watertightly surrounds the periphery of the earthquake isolation plate, and has gas sealed inside.
