Framed sleeper unit
A framed sleeper unit comprises two longitudinal sleepers and a plurality of horizontal sleepers. The horizontal sleepers are arranged between the longitudinal sleepers to form the frame sleeper unit. Two ends of each longitudinal sleeper are provided with joint structures to link two adjacent framed sleeper units. The frame sleeper units are laid on a granular-mixture ballast bed or a concrete ballast bed along a railway track direction, and rails are placed on a rail bed and connected with the sleepers through a fastening system. The framed sleeper unit has the advantages that under wheel load action, crushing never occurs to the rail seat; contact areas of the sleepers and the ballast bed are expanded, pressure applied to the top face of the ballast bed is reduced, and stability of the rail structure is improved; influence of wheel rail impact load to the ballast bed is reduced; rail support uniformity is enhanced, and rail surface dynamic harshness is maintained; maintenance of the ballast track of a high-speed railway is facilitated, and maintenance cost is lowered.
