基于智慧建造的“华龙一号”钢筋施工技术优化研究

Study on the Optimization of HPR1000 Steel Reinforcement Construction Technique Based on Intelligent Construction

“华龙一号”是我国自主研发的百万千瓦级第三代压水堆核电厂,在“华龙一号”重大设计改进中,将抗震设计基准提高到了0.3g加速度,据此设计,“华龙一号”堆型核电厂钢筋量达到了10万t,较第二代核电堆型,钢筋直径大、分布密集,施工难度较大。针对传统钢筋施工工艺的不足,漳州华龙科创团队通过技术攻关,共提出了两种切实可行的优化方案,分别是钢筋绑扎机器人技术和钢筋模块化施工技术。在钢筋绑扎机器人自动化领域,研制了墙体立筋上料装置、墙体水平钢筋上料装置、墙体钢筋抓举机器人,实现使用机器人代替人工完成钢筋施工工艺的部分工序;在钢筋模块化施工领域,研制了异型墙体钢筋模块化施工技术和直墙钢筋模块化施工技术,缩短主线工期;整体经济社会效益显著,对今后同类型工程施工具有重要的技术参考价值。

HPR1000 is self-developed 1000 MWe third-generation PWR nuclear power plant.In the major design improvement of HPR1000,the seismic design benchmark increased to 0.3g acceleration.According to this design,the amount of steel reinforcement in the HPR1000 type nuclear power plant has reached 100,000 tons,and compared with the second-generation nuclear power reactor type,the steel reinforcement has a larger diameter and denser distribution,making it more difficult to construct.In view of the shortcomings of traditional steel reinforcement construction process,the Zhangzhou Hualong Kechuang team has put forward two feasible optimization schemes through technical breakthroughs,respectively,the steel reinforcement binding robot technique and the steel reinforcement modular construction technique.In the field of steel reinforcement binding robot automation,the wall reinforcement feeding device,the wall horizontal reinforcement feeding device,and the wall reinforcement grasping robot were developed,so as to realize the use of robots instead of manual completion of part of the process of reinforcement construction process;In the field of modular construction of steel reinforcement,the modular construction technique of special-shaped wall reinforcement and the modular construction technique of straight wall reinforcement were developed to shorten the construction period of the main line;The overall economic and social benefits are remarkable,and it has important technical reference value for the construction of the same type of project in the future.
