摘　　要：浙江方家山核电工程为国产百万千瓦级压水堆核电机组,凝汽器是汽轮发电机组的重要组成部分,其壳体模块尺寸大、质量重,同时受汽机房结构限制,传统施工方案无法满足安装施工要求。根据凝汽器壳体模块结构特点及施工环境,研究采用了4台起重机联合作业、多次换钩、汽机房横梁临抛的施工新技术,配套研发了新型施工技术中使用的吊装构架,完成了4件吊点尺寸不同的凝汽器壳体模块的施工安装任务。The shell is one important part of steam turboset condenser.Fangjiashan nuclear power project in Zhejiang Province is the domestic level of millions of PWR nuclear power station.Its condenser shell modules have large size and heavy weight.At the same time by turbine room structure restriction,the traditional construction scheme is unable to satisfy the installation requirements.According to the condenser shell module structure characteristics and construction environment,the new construction technology such as for cranes integration operation,many times of changing hook,temporary hanging on the beam of turbine room,is studied and adopted.The supporting lifting frame is researched and developed.Four pieces of condenser shell modules with different hanging point size are successfully constructed.
