PURPOSE: A cylindrical water tank structure and a manufacturing method thereof are provided to safely store the water by preventing the contamination of the water due to the corrosion of a welded portion by installing a plate member and a waterproof sheet separately. CONSTITUTION: A structure of a cylindrical water tank(100) is composed of a concrete bottom(110), a bottom fixture(130), an inside fixture, and a waterproof sheet(140). At least one plate member(120,120a) is connected to the concrete bottom. The bottom fixture is radially fixed to the concrete bottom. The inside fixture is fixed to be spaced at the fixed angle. The waterproof sheet is closely contacted to the bottom fixture and the inside fixture to waterproof the inside of the concrete bottom and the inside of plate member, in which the end part of the waterproof sheet is overlapped to store the water. |
