摘　　要：依托于钢结构工程施工的便捷性及其施工技术发展的成熟,国内钢结构工程项目体量不断发展。钢结构柱脚二次灌浆施工因其工程量小、工序往往不在工期关键线路上等因素,导致二次灌注的施工质量一直未得到质量监督管理的重视,对提高二次灌注混凝土密实性的办法也缺少技术研究。论文通过天津海吉星国际农产品物流园某钢结构厂房项目,对钢结构柱脚二次灌浆工艺中质量控制进行总结归纳,并创新研发一种柱脚灌浆工具,有效解决了柱脚二次灌浆不密实等质量缺陷,为后续类似工程施工提供了参考。Relying on the convenience of steel structure construction and the maturity of construction technology development,the volume of domestic steel structure engineering projects continues to develop.The construction quality of secondary grouting of steel structure column foot has not been paid attention to by quality supervision and management because of its small engineering amount and the process is often not in the key line during the construction period,and the method of improving the density of secondary grouting concrete is also lacking of technical research.Through a steel structure plant project in Tianjin Haijixing,this paper summarizes and concludes the quality control in the secondary grouting process of steel structure column feet,and proposes an innovative grouting tool for column feet,which effectively solves the quality defects such as non-dense secondary grouting of column feet,and provides reference for the subsequent construction of similar projects.
