HEIGHT ADJUSTING BEARING METHOD OF VIBRATIONPROOF SLEEPER FOR RAIL

摘要

PURPOSE: To conduct the raising operation of the place of the installation of a concrete sleeper smoothly when the concrete sleeper settles. ;CONSTITUTION: The underside of a concrete sleeper 6 is borne through a sleeper bearing pad 7 in a sleeper bearing box 5 installed to concrete ballast 1. A height adjusting pad 8 in thickness corresponding to the settling section of the sleeper bearing box 5 (that is, the bearing surface of the concrete sleeper 6) is interposed under the sleeper bearing pad 7. An internal-end height adjusting plate 10 having height close to the height of a sleeper-pad bearing surface raised by adding the height adjusting pad 8 is bonded with the sleeper bearing box 7, and raising concrete 1a is placed up to the same height as the internal- end height adjusting plate 10 on the outside of the internal-end height adjusting plate 10.;COPYRIGHT: (C)1996,JPO
