METHOD FOR MANUFACTURING A PREFABRICATED DIRECT FASTENED TRACK HAVING A THREE-DIMENSIONAL SHAPE AND A CONCRETE DIRECT FASTENED TRACK CONSTRUCTION METHOD USING A PREFABRICATED DIRECT FASTENED TRACK MANUFACTURED BY THE METHOD

摘要

PURPOSE: A method for manufacturing a prefabricated direct fastened track having a three-dimensional shape and a concrete direct fastened track construction method using a prefabricated direct fastened track manufactured by the method are provided to improve the coupling force and fitness between concrete roadbed and a direct fastened track fastening device.;CONSTITUTION: A method for manufacturing a prefabricated direct fastened track having a three-dimensional shape is as follows. A temporary assembly line is installed. A temporary rail is installed in the temporary assembly line, corresponding to horizontal alignment, slope, and cant that are planned in a field. Concrete roadbed(30) having a three-dimensional shape corresponding to the horizontal alignment, slope, and cant of the temporary rail is formed on the temporary rail. A direct fastened track fastening device is installed on the concrete roadbed, and the concrete roadbed is cured.;COPYRIGHT KIPO 2012
