CONSTRUCTING METHOD OF DIRECT FIXATION TRACK ON THE CONCRETE USING THE SETTING RAILS

摘要

PURPOSE: A concrete direct fastened track construction method using auxiliary track frames is provided to facilitate the construction of a concrete direct fastened track that linearly varies in a plane curve. CONSTITUTION: A concrete direct fastened track construction method using auxiliary track frames is as follows. A planned alignment is measured, and an auxiliary track frame(10) including an adjustment rail(10a) is installed corresponding to the planned alignment on a railway roadbed. Concrete roadbed is placed around the auxiliary track frame and cured. A direct fastened track fastening device is installed on the concrete roadbed. A track rail is installed on the direct fastened track fastening device.
