核电站反应堆厂房筏基钢筋笼模块化施工技术

Modular Construction Technology of Raft Foundation Reinforcement Cage for Reactor Building in Nuclear Power Plant

借鉴国外核电站反应堆厂房实施筏基钢筋笼模块化施工的成功经验,对CPR1000型核电站反应堆厂房筏基钢筋笼模块化技术进行研究。通过对4种筏基钢筋笼模块化设计方案的比对和综合评估,提出推荐方案。研究开发了适用于筏基钢筋笼模块化施工的特殊吊具。针对某拟采用筏基钢筋笼模块化施工的示范项目实际情况,进行筏基钢筋笼模块化施工方案的研究,包括起吊模块吊车选型及其站位、模块化施工对施工场地的要求等。该研究成果为国内核电工程全面推行筏基钢筋笼模块化施工打下了基础。

Based on oversea successful experience in the modular construction technology of raft foundation reinforcement cage （RFRC） for reactor building in nuclear power plants,this modular construction technology for the reactor building in CPR1000 nuclear power plant is studied.Through the comparison and comprehensive evaluation of four kinds of modular design schemes of RFRC,a recommended scheme is proposed,and a special spreader was researched and developed for the RFRC modular construction.Furthermore,the RFRC modular construction scheme of a demonstrative project which will adopt the RFRC modular construction technology is studied,including the selection of cranes for lifting modules and crane positioning,construction site requirement for modular construction.The research results would lay a technological foundation for the all-round implementation of RFRC modular construction in nuclear power plants in China.
