Abstract
Description
Technical Field
[0001] This application relates to the technical field of seismic reinforcement of oil tanks, and more specifically, to a seismic reinforcement device for petrochemical equipment. Background Technique
[0002] An oil tank is one of the most common petrochemical equipment. In order to improve the seismic resistance of the oil tank, when installing the oil tank, generally, the foundation is thickened, reinforced concrete supports are installed, and a seismic pad is used to install the oil tank. Through seismic reinforcement treatment, unnecessary economic losses can be reduced during an earthquake disaster, achieving the purpose of saving resources. However, the traditional methods of thickening the foundation, installing reinforced concrete supports, and using a seismic pad have general seismic energy absorption effects and are only suitable for general low-level earthquake grades. Moreover, there is no reinforcement mechanism outside the tank body, so the rolling phenomenon is likely to occur, and the firmness still needs to be improved. In view of this, we propose a seismic reinforcement device for petrochemical equipment. Content of the Utility Model
