Nuclear power station containment steel lining thin shell type hemispherical dome structure and manufacturing method thereof
The invention discloses a nuclear power station containment steel lining thin-shell type hemispherical dome structure and a manufacturing method thereof, a dome block plate is formed by splicing and welding unit plates, the inner side of the block plate is brushed with nuclear-grade anticorrosive paint, and the outer side of the block plate is welded with transverse and longitudinal stiffeners and anchoring nails; after being prefabricated in a workshop, the block plates are spliced into a whole on site, and finally the whole block plates are hoisted in place through large hoisting equipment. According to the method, key technologies such as plate parting optimization, forming die optimization, stiffening rib addition and curved surface submerged arc welding are adopted, and the problems that radian forming is difficult, deformation control is difficult, and the dimensional precision requirement is high are solved; a unit plate splicing submerged-arc welding technology, a block plate moulding bed one-time forming technology and a large-breadth block plate splicing technology are adopted, so that the construction period is shortened, the cost is saved, and the overall construction progress of the steel lining dome is ensured. The method has the advantages of being high in forming quality, small in welding deformation, high in construction efficiency and capable of reducing the on-site splicing amount.
本发明公开了核电站安全壳钢衬里薄壳式半球形穹顶结构及其制造方法，穹顶分块板由单元板拼焊而成，分块板内侧刷核级防腐涂料，外侧焊接横纵向加劲和锚固钉；分块板在车间预制完成后，现场进行拼装成一个整体，最终采用大型起重设备整体吊装就位。本发明采用优化板块分型、胎模、附加加劲肋、曲面埋弧焊等关键技术，解决弧度成型难、变形控制难、尺寸精度要求高的难题；采用单元板拼接埋弧焊技术、分块板胎模一次成型技术和大幅面分块板拼装技术，缩短工期、节约成本，确保了钢衬里穹顶的整体施工进度。本发明具有成型质量高、焊接变形小、施工效率快、减少现场拼装量的优点。
