REINFORCING DEVICE OF AN OIL STORAGE TANK LAID UNDER THE GROUND

摘要

The present invention relates to a reinforcement device for an underground buried oil storage tank. In particular, a tank (1) in which a hemispherical disc (12) is welded to openings at both sides of a body portion (11) formed by rolling a steel plate into a cylindrical shape and welding a contact surface thereof. )Wow; An FRP (2) covered with a predetermined space portion outside the tank (1); The oil supply oil supply pipe 13, the oil discharge oil supply pipe 14, the vent pipe 15, and the oil leak detection pipe which are installed in the vertical direction at a predetermined interval on the tank 1 installed horizontally with respect to the bottom. In the underground buried oil storage tank having 16), the corrugated reinforcement protrusions 11A are integrally bent at predetermined intervals in the vertical direction of the cylindrical body portion 11, thereby being applied from the upper portion of the tank. It is possible to prevent the tank itself from being deformed due to the load being loaded or the gravity of the contents.As the tank is deformed due to the gravity and the load, cracks are generated at the welded parts of the pipes. It can be prevented in advance.
