摘要

PPROBLEM TO BE SOLVED: To provide a semi-underground flat bottom cylindrical liquid storage tank and its construction method by excavating the ground and constructing a flat bottom cylindrical tank on the excavated bottom face and filling a banking material so as to work an inward pressure in contact with the outer peripheral face of the tank body. PSOLUTION: The ground is excavated down as deep as a semi underground depth and a flat bottomed cylindrical tank for storing a low temperature liquid is installed on the excavated bottom face and a slide face is formed at the outer peripheral face of the tank and further, a banking earth is filled up to a certain height so as to work the earth pressure inward on the outer peripheral face of the tank body by use of the excavated earth or the like.
