Title:
GROUND VIBRATION REDUCING DEVICE AND GROUND VIBRATION REDUCING METHOD
Document Type and Number:
Japanese Patent JP2016023516
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a ground vibration reducing device and a ground vibration reducing method that do not require excavation to a great depth, earth retaining and closing of an opening as in a case of vibration-proof groove formation, do not increase the costs of temporary construction excessively because back-filling and earth retaining wall removal at the time of construction end are not required, do not require excessive costs for construction and removal of a wall body as in a case of vibration-proof wall formation, do not alter a ground structure or affect an inclination in surrounding grounds, and can reduce vibration from construction work for certain.SOLUTION: A ground vibration reducing device includes a frame 2 buried under a ground 1 and installed on a supporting ground 11, a vibration-proof body 3 installed on the frame, and a mass body 4 mounted on the vibration-proof body, the mass body being allowed to change its weight. The ground vibration reducing device adjusts the weight of the mass body and an elastic coefficient of the vibration-proof body, for vibrating at a vibration number that resonates with the vibration number of an object to be controlled.SELECTED DRAWING: Figure 1
