臺北捷運蘆洲線位於地下段無道碴道床特殊軌道區採用之軌床型式與其它已營運之路段 採用相同之混凝土版，因其控制鋼軌扣件安裝位置的平整性要求高，且需兼具施作便利、提 供通路與確保作業品質穩定等特性，故在混凝土版施築完成後，自鋼軌扣件之錨定套管植入 及承載面製作等階段之作業程序和品質，常影響特殊軌組裝整體品質與穩定，雖此一階段作 業屬環節中一部分，惟常扮演決定性的角色。 本文乃就施工廠商規劃混凝土版施築完成後至特殊軌組裝前之鋼軌扣件之錨定套管植入 至承載面製作過程中之作業順序調整及作業分工獲致之效益與前行標做法比較說明，供後續 施工廠商執行參考。

Taipei MRT Luzhou line’s direct fixation fastener (DFF) non-ballast special trackwork rests on the same type of slab as those adopted for MRT lines currently in service. Installation of the fasteners plays a key role in the construction of successful special trackwork, in particular, the evenness of the fastener position is a strict requirement. However, DFF features easy operation, allows space of passage during construction as well as assured quality. In the pre-operation of Luzhou line’s non-ballast special trackwork, after the track slab is cast in-situ, the quality of DFF non-ballast special trackwork will depend on the procedures to build-in the anchor male cone and the quality of the bearing surface in this crucial step in the installation stage, even though these activities constitute only a part of the overall assembly work. This paper addresses the work sequence and details of these two major activities, i.e. fastener insert implanting and base-plate bearing surface finishing, which are implemented in the Taipei MRT Luzhou line. Also, associated benefits compared with corresponding activities applied in previous MRT construction are discussed, intending to provide a reference for future Taipei MRT construction.
