核电站钢衬里模块化吊装技术的研究与应用

Research and Application of Modular Hoisting Technology for Nuclear Power Plant Steel Lining

随着我国核电的快速发展,后续第三代核电华龙一号机组大部分施工工艺以模块化为主,采用模块工厂预制、模块地面拼装、模块整体吊装的模式,可大大提高施工质量,降低高空作业风险,缩短工期。本文主要对钢衬里模块化吊装施工应用进行简要的介绍,主要从吊索具的选择、履带起重机选型及吊装过程控制三方面进行阐述,为华龙一号钢衬里模块化吊装提供宝贵的实践经验。

With the rapid development of nuclear power in China,most of the subsequent third generation nuclear power Hualong No.1 unit construction processes are mainly modular.The mode of module factory prefabrication,module ground assembly,and module integral hoisting can greatly improve the construction quality,reduce the risk of high-altitude operation,and shorten the construction period.This paper mainly introduces the construction application of modular hoisting of steel lining,mainly from three aspects:selection of slings,selection of crawler cranes and control of hoisting process,which provides valuable practical experience for modular hoisting of Hualong No.1 steel lining.
