UNDERGROUND TANK WITH EXTERNAL WALL
Document Type and Number:
Japanese Patent JPS5563100
Kind Code:
A
Abstract:
PURPOSE:To protect the tank that contains liquid of ultralow temperature by preventing freezing of the area beyond a fixed distance from the tank by providing an adiabatic wall surronding the outer circumference with spacing at a fixed distance from the embeded tank in the underground. CONSTITUTION:The adiabatic wall of foam concrete is provided to the outer circumference at a distance l from the embeded tank 1 that contains liquid of ultralow temperature in the underground. By this, the soil around the tank is cooled and moisture in the soil is frozen, however, the area beyond the adiabatic wall is not cooled, the soil is not frozen.
