FLOATING ORBIT STRUCTURE TO PREVENT VIBRATION AND CONSTRUCTION METHOD THEREOF

摘要

PURPOSE: Provided is a floating orbit structure to prevent vibration which includes a vibration-proof mat to absorb vibration delivered to concrete ground so that it contributes to protect a concrete ground and an orbit slab. CONSTITUTION: The floating orbit structure to prevent vibration is characterized by placing the vibration-proof mat(30) on a slab groove of concrete ground(T), pouring an orbit slab(25) into the vibration-proof mat and placing a rail(1,1') on the orbit slab wherein the upper side of the vibration-proof mat is lower than that of the slab groove with inserting a backup material into space above the vibration-proof mat and sealing a sealing agent into space above the backup material.
