Base plate fastening system and method for pre-stressed concrete sleeper

A base plate fastening device and method for a PC(Pre-stressed Concrete) railroad tie are provided to adjust or maintain the rail gauge by installing eccentric bushes comprising tapered tubular bodies, and annular flanges into eccentric through holes on the base plate. In a fastening device using screw spikes to fasten a base plate(51) for a PC railroad tie, the base plate has through holes(53) drilled through upper and lower surfaces of the base plate. Eccentric bushes(55), or double eccentric bushes are inserted into the through holes. The eccentric bushes include tubular bodies(59) having preset diameters and lengths, annular flanges(61) disposed on an outer circumference of an upper end of the tubular bodies, and a tapered outer surface(63).
