Abstract

PURPOSE:To enable not only a load from the outside of a tank but also boiled gas pressure in the tank to be effectively dealt with by embedding a steel sheath having a built-in steel material in the outer peripheral wall of concrete and applying a prestress force to this steel material. CONSTITUTION:A steel sheath 8 having a built-in steel material 7 is embedded in the outside of the outer peripheral wall 4 in the longitudinal and lateral direction thereof. To the steel material 7 is applied a prestress force by a jack or the like in a proper period after execution of the outer peripheral wall 4. Thus, internal stress in the outer peripheral wall 4 of a tank is always maintained under the compressive stress so that the tank can effectively deal with a load added from the outside to the outer peripheral wall 4 of the tank, gas pressure from the interior, thermal stress, etc. while ensuring liquid and gas tight for a tank container.

Description

【発明の詳細な説明】 この発明は地下にトンネル方式等で構築される液化ガス
貯蔵用地下タンクに関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an underground tank for storing liquefied gas constructed underground using a tunnel method or the like.

とが重要な要件となる。Storage tanks for low-temperature liquefied gases such as LNG and LPG include
In addition to the function of safely retaining liquid against external loads and intrusion of groundwater, it is important to have liquid-tight and air-tight performance to prevent liquefied gas from leaking from the inside or outside under low drainage conditions. It becomes a requirement.

ことは、地中温度の安定性あるいは地上の天変地異の影
響を受は難いという安定した構造環境を具備しており、
これらの利点を積極的に利用することは大きな意義を有
するところである。In this case, creating an underground space below the earth's surface to store liquefied gas provides a stable structural environment that is unlikely to be affected by underground temperature stability or natural disasters above ground.
It is of great significance to actively utilize these advantages.

ルオフガスが地上に突出する危険性があった。However, although the conventional 1MIa technology for storage tanks can effectively cope with loads from outside the tank such as tunnel ground pressure, it does not have the function of a safe pressure vessel against internal pressure inside the tank. - Therefore, if a crack occurs in the outer wall of a tank due to internal pressure, surrounding groundwater will enter through the crack and react with the low-temperature liquefied gas such as LNG stored in the tank, resulting in rapid boil-off. Gas was generated, and this gas pressure created an abnormally high pressure inside the tank, posing a risk of damaging the tank itself and causing boil-off gas to protrude to the ground.

また液化ガスの漏出は、地盤中への可燃性ガスの浸透を
意味し、非常に危険であるばかりでなく、これらの液化
ガスが低温であることからタンク周辺地盤の凍結範囲を

な影響を及ぼすことになる。Furthermore, leakage of liquefied gas means penetration of flammable gas into the ground, which is not only extremely dangerous, but also because these liquefied gases are low-temperature, it gradually increases the frozen area of the ground around the tank. This will have a significant detrimental effect on the surrounding environment, such as ground frost heaving.

せるという問題も派生していた。Furthermore, when a cold insulation layer is formed in an underground tank, the intrusion of groundwater etc. causes a significant decrease in the insulation performance of the cold insulation layer, leading to the problem that the storage function as a low temperature tank is significantly reduced. .

ろにある。This invention was made with attention to the above-mentioned problems, and its purpose is to install a steel tank with steel material housed inside the outer circumferential wall of the tank, which is made of reinforced concrete, in an underground tank for storing liquefied gas. By embedding a sheath, applying prestress force to the steel material, and maintaining the outer circumferential wall in a compressive stress state, it has liquid-tightness and airtightness that can effectively cope with the internal and external pressures applied to the tank outer circumferential wall. Underground tanks are provided, and a cold insulating material is attached to the entire inner surface of the tank's outer peripheral wall to reduce the amount of boil-off gas due to heat input from the outside and to prevent freezing that develops on the outer periphery of the underground tank. It provides an underground tank that can control the atmosphere.

The surface of this cold insulating material is protected by a coating film 12, and the purpose of the coating film 12 is to protect the cold insulating material 9 in terms of durability, moisture absorption, etc., and to provide liquid tightness. The material used is one that does not crack or peel off due to temperature gradients, etc.

By reducing the temperature in step 3, the temperature outside the tank outer wall 4 is close to that of the ground 15, and the frozen soil range 16
This makes it possible to prevent abnormal increases in frozen soil pressure due to the development of frozen soil, and to improve the cooling performance of the tank.
