“华龙一号”穹顶组合壳胎架选型与施工技术

Selection and Construction Technology.of Combined Shell Bed-Jig for"Hualong One"Dome

为满足“华龙一号”穹顶拼装施工要求,提出一种适用于核电穹顶吊装施工的胎架结构,并采用遗传算法对结构参数进行了优化。为该新型胎架结构量身设计了施工工艺,实现了原位快速机械化拼装和拆除的目标。通过“华龙一号”工程应用,验证了所设计穹顶胎架结构的经济性和高效性,且胎架可重复利用,可在核电行业穹顶拼装施工中推广。

In order to meet the requirements of"Hualong One"dome assembly construction,a bed-jig structure suitable for nuclear power dome hoisting construction is proposed,and the structural parameters are optimized by genetic algorithm.The construction process is designed for the new type of bed-jig structure,and the goal of in-situ rapid mechanized assembly and disassembly is achieved.Through the application of"Hualong One"project,the economy and efficiency of the designed dome bed-jig structure are verified,and the bed-jig can be reused and popularized in the dome assembly construction of nuclear power industry.
