摘　　要：以长春市城市轨道交通6号线南部新城西站装配式车站施工实际情况为例,通过对预制装配式构件张拉施工技术进行深入研究,发现采用张拉辅助装置可有效解决地铁装配式车站预制构件在张拉部位呈凹槽形状,且凹槽较深,传统张拉设备中的穿心千斤顶无法深入,狭窄的凹槽内也无法满足封锚作业所需的操作空间的难题,为类似工程提供参考。Based on the actual construction situation of prefabricated station in South Xincheng West Station of Changchun urban rail transit Line 6,this paper finds that the prefabricated component in subway prefabricated station can be effectively solved by using tension auxiliary device in the shape of groove in the tension position,and the groove is deep.The core jack in traditional tensioning equipment can not be penetrated,and the narrow groove can not meet the operational space required for anchor sealing operation,Provide a reference for similar projects.
