Method for replacing bottom plate of large vertical storage tank of nuclear power station
The invention belongs to a replacement method, and particularly relates to a method for replacing a large vertical storage tank bottom plate of a nuclear power station. The method comprises the following steps: 1, designing a lifting device; 2, testing the performance of the lifting device; and 3, replacing and implementing the on-site bottom plate. The invention has the following remarkable effects: 1) the structure is stable and the reliability is high; (2) the tank body is uniformly stressed, and the deformation is small; and (3) the operation time in a closed space is reduced, and the probability of construction accidents is reduced. And 4) the tank body is lifted stably. And 5) the lifting device is convenient to manufacture, low in cost and high in economic benefit.
本发明属于更换方法，具体涉及一种核电站大型立式储罐底板更换方法。它包括：步骤一：提升装置的设计；步骤二：提升装置性能试验；步骤三：现场底板更换实施。本发明的显著效果是：1)结构稳定，可靠性高。2)罐体受力均匀，变形量小。3)减少了密闭空间作业时间，降低了施工事故发生的几率。4)罐体提升平稳。5)提升装置制作方便，成本低廉，经济效益高。
