摘要： PROBLEM TO BE SOLVED: To simply and safely construct a storage tank in a short time, by forming a cylindrical bag body having a flat bottom provided with a dome- shaped roof section made of a flexible membrane material and feeding a fluid into the bag body to expand it and further, sticking a solidifying solvent to the external face of the expanded bag body. SOLUTION: A bag body 1 made of a flexible membrane material and formed to have a cylindrical body with a flat bottom provided with a dome-shaped roof section IC is fixed to a bottom slab 2 or a base rock. A feed inlet 5 is provided at the lower part of the side part 1B of the bag body 1 and a fan 7 is installed through an air feed duct 6. Then, after air is sent inside the bag to raise the pressure and inflate the bag body 1, a solidifying solvent 8 is applied on the external face. In this time, air of a pressure higher than the storage gas pressure is sent, airtightness and pressure tests of the storage tank can be simultaneously carried out. Fiber reinforced resin, mortar, concrete, etc., are used for the solidifying solvent. When the same kind of material with the bag body 1 is contained, a high adhesiveness and fusibility can obtained.

摘要： PROBLEM TO BE SOLVED: To prevent movement of a horizontal direction such as earthquake, and aim at stabilization by arranging a projection/recessed shaped fitting part on upper and lower contact surfaces of a mold body so as to converge movement of the horizontal direction to a ring part cold reserving layer composed of a mold body of a laminated structure arranged on a lower part of an inner tank side plate lower part. SOLUTION: A ring part cold reserving layer 8 arranged on a lower part of an inner tank annular plate 12 just under an inner tank side plate 9, is formed by laminating mold bodies 16 which are mold-manufactured by perlite concrete and the like in a factory and the like beforehand. A fitting part 19 composed of a recessed part 17 and a projection part 18 which are fitted mutually to surfaces that are brought into contact with upper and lower parts at the time of laminating, is arranged on the mold body 16. In a lowest layer mold body 16A made of perlite concrete which is executed at a job site, ensures predetermined compression strength, and can be tightly fixed so as to suppress movement by a fixing member 15. It is thus possible to hold a stable load supporting condition without moving a ring part cold reserving layer in a horizontal direction by the earthquake.
