To provide a dual-structured cryogenic tank that stores cryogenic liquid inside, the objective is to provide a highly reliable cryogenic tank that is simple in construction and easy to install, while reducing construction costs. And For this purpose, a bottomed cylindrical low-temperature tank having a double structure comprising an inner tank (3) for storing a low-temperature liquefied fluid (L) inside and an outer tank (6) provided outside the inner tank (3) ( 100), the inner tub (3) includes an inner container (1) made of concrete, and an inner cooling / resistance resistance layer (2) covering the inner surface of the inner container (1), and surrounds the inner tub (3). The outer tub (6) to be provided includes an outer container (4) made of concrete and an outer cooling resistance reducing layer (5) that covers the inner surface of the outer container (4). |
