摘　　要：介绍大亚湾核电站虹吸并消泡改造工程施工技术。利用机组停机时间进行施工,采用大型预制件龙门吊水上直接吊装方案,采用刚性钢构件结合掺水玻璃速凝水泥浆灌浆技术解决预制件动水中晃动问题。The purpose of this paper is mainly to introduce the construction technique of siphon well defoam structure of Daya Bay nuclear power station performed during the unit stopping for maintenance. The large precast structure should be directly erected using the composed overhead crane.The wobbling of the precast structure in the rapid flow could be solved through setting the rigid steel components and the speedup-concreting grout grouting with water glass.
