摘要:
PBA暗挖地铁车站由于洞内高度受限,无法用吊车作业,钢管柱通常在洞内拱顶预埋或焊接吊钩进行吊装。但受清华大学附中坍塌事件影响,为确保初期支护结构绝对安全,总监办及相关方面禁止采取传统方法施工。为此专门设计并制作一种新型钢管柱吊装台车,通过在16号线玉渊潭东门站施工中的应用,表明台车吊装技术能完全替代传统方法,完全消除对初期支护稳定的影响,避免安全隐患,且台车使用简单高效,节省近1个月工期,确保了施工进度与安全。

Abstract:
Due to the height limit in tunnel of PBA mined Metro station, the steel pipe column hoisting trolley can not be used. The preembedded steel pipe column and welding hoisting method are prohibited so as to guarantee the safety of primary support. The application of a new steel pipe column hoisting trolley to Yuyuantan East Station shows that the abovementioned trolley is easy and highefficient, and can guarantee the safety of primary support.
Key words: Yuyuantan East Station, Metro station, PBA, steel pipe column, hosting in pilot tunnel, new trolley
