VIBRATION REDUCTION STRUCTURE AND CONSTRUCTION METHOD OF VIBRATION REDUCTION STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a vibration reduction structure or the like which is applicable even to weak ground or the like and is capable of executing noise/vibration measures for a traffic route or the like.

SOLUTION: A rigid reinforcement body 5 is disposed on natural ground 3 which is the weak ground. A roadbed 13 and a ballast 15 are constructed on the rigid reinforcement body 5 and sleepers 17 and rails 19 are installed on the ballast 15 to attain a railroad track. The rigid reinforcement body 5 comprises a planar reinforcement material 7, cylindrical bodies 9 arranged in a lattice shape on an upper surface of the planar reinforcement material 7, and a fluid solidification material 11 filled inside the cylindrical bodies 9. The cylindrical bodies 9 include longitudinal cylindrical bodies 9a disposed along an advancing direction of the rails 19 and traverse cylindrical bodies 9b disposed in a direction roughly perpendicular to the longitudinal cylindrical bodies 9a. An interval 27 between the longitudinal cylindrical bodies 9a is set to be equal to or shorter than a length 21 of the sleeper 17.
