Title:
CURVE PART TRACK STRUCTURE AND BALLAST RESHAPING MATERIAL
Document Type and Number:
Japanese Patent JP2014163143
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a lightweight curve part track structure excellent in workability, drainability and processability.SOLUTION: A curve part track structure comprises ballast laid on a roadbed and first and second roadways mutually laid in parallel on the ballast, and the first and second roadways constitute a curve part with the second roadway side as the inside. The first roadway is composed of a first sleeper, a first outer-orbital rail and a first inner-orbital rail. The second roadway is composed of a second sleeper, a second outer-orbital rail and a second inner-orbital rail. A position of the first and second inner-orbital rails and the first and second outer-orbital rails is adjusted so that displacement is not caused in a height of the first and second inner-orbital rails and the first sand second roadways have a cant amount corresponding to a desired design speed. A first bulk increase part generated in the curve outside direction of the first roadway and a second bulk increase part generated between the first roadway and the second roadway, are reshaped by a ballast reshaping material formed in a net shape by positioning.
