Description

  The present invention relates to a sleeper connecting structure capable of reducing deterioration such as wear at the end of a sleeper, and also relates to a method for repairing the end of a sleeper.

  As a method of installing the rail, a method of providing a sleeper on the ballast and supporting the rail on the sleeper is used. When the train passes on the rail, the sleeper receives a train load.

  In particular, at rail joints and branches, the bending rigidity of rails is low compared to other parts, and ballast consolidation is likely to occur due to train load, and track settlement tends to occur. The “tilting phenomenon” is likely to occur.

  The sleeper is worn by friction with such ballast. In particular, the end of the sleeper tree is subject to wear because it moves up and down while receiving lateral pressure. And this abrasion occurs in the part which contacts a ballast, and it generate | occur | produces unevenly, and surfaces, such as a muzzle surface of a sleeper tree, will be in an uneven state.

  In addition, when a train passes through a branch portion or the like, a large force is applied in the lateral direction of the roadbed (perpendicular to the rail direction) or in the vertical direction of the roadbed (parallel to the rail direction). Therefore, the force acting between the end portion of the sleeper tree and the ballast becomes stronger, and the wear is likely to occur.
