To largely reduce cost by implementing a countermeasure while operating a tank without requiring to remove and transfer an existing pipe, while easily implementing a local part slide countermeasure of an existing structure such as an existing tank.
A required safety factor 1.1 is secured by improving a safety factor by increasing a resistance force to a slide by driving a plurality of steel bar-shaped members 3 such as a well point pipe and a reinforcement of a thick diameter at a predetermined interval in the tank radial direction in a predetermined range in the tank radial direction of the outside peripheral ground of the existing tank 1 to the local part slide surface (a circular arc slide surface) A of the existing tank (an old law tank) 1 manufactured at an old standard. The bar-shaped members 3 are arranged in an existing area of the local part slide A so as to penetrate the local part slide surface A, and also arranged in an outside area of the local part slide surface A, and the required resistance force is secured.
