Abstract
Official abstract text for this publication.
An above-ground low-temperature tank includes a metal inner tank which stores low-temperature liquefied gas, and an outer tank which includes a concrete outer wall surrounding the inner tank. A hole portion which has a preset depth from a bottom surface of the inner tank is formed on a bottom portion of the inner tank, and a metal pit main body having a cylindrical bottomed accommodating portion is provided in a state where the accommodating portion is accommodated in the hole portion. A reinforcing body which supports at least an outer circumferential edge portion of a bottom surface of the pit main body is provided on the bottom surface side of the pit main body in the hole portion. A cold insulation material is provided below the reinforcing body.
First claim
Opening claim text (preview).
What is claimed is: 1 . An above-ground low-temperature tank, comprising: a metal inner tank which stores low-temperature liquefied gas; and an outer tank which includes a concrete outer wall surrounding the inner tank, wherein a hole portion which has a preset depth from a bottom surface of the inner tank is formed on a bottom portion of the inner tank, and a metal pit main body having a cylindrical bottomed accommodating portion is provided in a state where the accommodating portion is accommodated in the hole portion, a reinforcing body which supports at least an outer circumferential edge portion of a bottom surface of the pit main body is provided on the bottom surface side of the pit main body in the hole portion, and a cold insulation material is provided below the reinforcing body. 2 . The above-ground low-temperature tank according to claim 1 , wherein compressed glass wool is disposed outside a side peripheral surface of the pit main body in the hole portion. 3 . The above-ground low-temperature tank according to claim 1 , wherein the reinforcing body is annularly formed to support the outer circumferential edge portion of the bottom surface of the pit main body, and the cold insulation material is provided inside the annular reinforcing body. 4 . The above-ground low-temperature tank according to claim 2 , wherein the reinforcing body is annularly formed to support the outer circumferential edge portion of the bottom surface of the pit main body, and the cold insulation material is provided inside the annular reinforcing body. 5 . The above-ground low-temperature tank according to claim 1 , wherein the reinforcing body is made of concrete. 6 . The above-ground low-temperature tank according to claim 2 , wherein the reinforcing body is made of concrete. 7 . The above-ground low-temperature tank according to claim 3 , wherein the reinforcing body is made of concrete. 8 . The above-ground low-temperature tank according to claim 4 , wherein the reinforcing body is made of concrete.
