                          电站钢结构存在的一般缺陷与解决策略

                          时间:2019-03-05 14:42作者:赵葳娜
                          本文导读:这是一篇关于电站钢结构存在的一般缺陷与解决策略的文章,电站钢结构在实际运作的过程中,除了承受保温系统以及汽水系统的压力和荷载之外,还需要承受机组运行过程中由于振动等各种因素所引起的疲劳荷载。疲劳荷载影响钢结构的正常使用和功能的有效发挥。

                            摘    要: 电站钢结构在实际运行的过程中需要承受高压、高温以及高负荷的作用,作为支撑整体电站的设计结构,对于电站生产活动的安全性和稳定性有着十分重要的影响。论文阐述电站钢结构的常见缺陷和问题,并提出相应的解决对策,以供参考。

                            Abstract: The steel structure of power station needs to bear the effects of high pressure, high temperature and high load during the actual operation. As the design structure supporting the whole power station, it has a very important influence on the safety and stability of power station production activities. This paper describes the common defects and problems of power station steel structure, and puts forward corresponding countermeasures, for reference.

                            2.3 、钢结构立柱翼板母材夹层

                            钢结构立柱翼板母材夹层是电站钢结构中最为常见的缺陷之一。技术人员在进行立柱翼板母材夹层的厚度检测的过程中,发现立柱一般的真实厚度要远超过通过超声波机械设备检测出来的厚度。技术人员为了保证检测结果的准确性,需要通过机械设备与人力检测相结合的方式,保证检测效果与检测质量。技术人员为了检测钢结构立柱翼板母材夹层是否存在夹层问题,采用纵波直探头进行了超声波检测并获得肯定的结果。这种夹层的存在会影响钢结构的安全性和稳定性,严重降低杆件的使用强度,影响电站机组的正常工作[3]。
