【摘要】：随着大跨度的重型钢结构的发展,在核电站设计和建造中也得到了较大的运用,且核电站中的重型钢结构一般形态各异,不属于标准的民用钢结构类型,所以按照一般民用钢结构施工的方法和质量管理要求,将难以达到核电质保等级的要求,出于对核安全的考虑,研究出一套重型钢结构在核电站设计和建造中的施工质量管理方法将是一个重要而现实的课题。在核电钢结构工程的制造、安装过程中,由于人员资质和技能、原材料、施工技术方案等因素的影响,不免出现各种质量问题,为了减少和提前发现并解决这些频发的质量问题,更加迫切需要研究一套适用于核电站的重型钢结构制造安装的质量管理方法来指导生产建设。通过海阳核电2#机组钢制穹顶结构的建造施工过程,来研究和探讨核电站大跨度重型钢结构质量管理方法,首先介绍了国内外的研究现状和核电钢结构工程的施工质量管理的要点和难点,并对难点进行了分析和总结。接着剖析了质量管理活动中常见的问题,并利用专家打分法对问题进行了分类和总结,归纳出质量管理问题的特征,后期结合质量管理问题的分类进行逐一解决处理。其次,结合4M1E的质量管理方法和核电现场管理的要求,利用分层法分析出常见质量问题的原因,以穹顶结构工程施工的质量管理全过程为实例,论文整体按照施工前期准备,施工实施过程,施工完工验收三个阶段的工作要点进行论述,明确了穹顶工程质量管理的方法,并针对常见的质量问题,在质量管理方法中加以说明,使质量管理方法不但能够有效的解决发生的质量问题,更能提前预防容易发生的质量问题。最后,阐述了穹顶工程的施工质量管理的实施保障措施。主要通过对组织体系和制度,质保程序、职责分工、人员授权管理的明确和细化,对质量管理过程中的重点和难点的实施提出了一些明确的措施,使质量管理的措施更为有效和顺利地实施。研究成果对核电站的大跨度重型钢结构工程的施工质量管理具有重要的指导作用,对国内其他核电同类工程的施工品质管理具有一定的借鉴价值。
[Abstract]:With the development of the large-span heavy steel structure, it has been used in the design and construction of nuclear power station, and the heavy steel structure in the nuclear power station is generally different in shape and does not belong to the standard civil steel structure type. Therefore, according to the general civil steel structure construction methods and quality management requirements, it will be difficult to meet the requirements of nuclear power quality assurance grade, out of nuclear safety considerations, It will be an important and realistic subject to study a set of construction quality management method of heavy steel structure in the design and construction of nuclear power station. In the process of manufacturing and installation of nuclear power steel structure projects, various quality problems inevitably occur due to the influence of personnel qualifications and skills, raw materials, construction technical schemes, etc. In order to reduce and solve these frequent quality problems, it is more urgent to study a set of quality management methods for manufacturing and installation of heavy-duty steel structures in nuclear power plants to guide production and construction. Through the construction process of steel dome structure of Haiyang nuclear power unit in 2#, the quality management method of large-span heavy-duty steel structure in nuclear power station is studied and discussed. This paper first introduces the research situation at home and abroad and the key points and difficulties of construction quality management of nuclear power steel structure engineering, and analyzes and summarizes the difficulties. Then the common problems in the quality management activities are analyzed, and the problems are classified and summarized by the expert scoring method, and the characteristics of the quality management problems are summed up, which are solved one by one with the classification of the quality management problems in the later stage. Secondly, according to the quality management method of 4M1E and the requirement of nuclear power field management, the causes of common quality problems are analyzed by stratification method. Taking the whole process of construction quality management of dome structure engineering as an example, the whole paper is prepared according to the pre-construction period. The main work points of the three stages of construction completion and acceptance are discussed, the methods of quality management of dome engineering are clarified, and the common quality problems are explained in the quality management method. So that the quality management method can not only effectively solve the quality problems, but also prevent the quality problems easily occurring in advance. Finally, the paper expounds the measures to guarantee the construction quality management of dome engineering. Through the definition and refinement of the organizational system and system, quality assurance procedures, division of duties, personnel authorization management, and the implementation of key and difficult points in the process of quality management, some clear measures are put forward. To make the quality management measures more effective and smooth implementation. The research results have important guiding function to the construction quality management of the large-span heavy steel structure engineering of nuclear power plant, and have certain reference value to the construction quality management of other similar nuclear power projects in our country.
