摘要

Procedure for replacing old sleepers (6) of a track (8) with new sleepers (11), in which the rails (7) detached from the old sleepers (6) are laterally separated from each other and, before the placement of the new sleepers (11), the construction of a ballast settlement plane (27) is carried out, characterized in that, in an area (25) of a ballast bed (33) located in front of the head of the sleepers and adjacent to the old sleepers (6) in the longitudinal direction of these, ballast (26) is collected to construct a cavity (31) in said bed, this ballast is temporarily stored and, after the placement of the new sleepers (11), it unloads it to perform the ballasting of said sleepers, and because in parallel with this, before the placement of the new sleepers (11), excess ballast (26) is plowed into the cavity (31) of the bench to construct the plane of Ballast settlement (27).
