VIBRATION-ISOLATING PILE, VIBRATION-ISOLATING WALL USING THE SAME AND ITS EXECUTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a vibration-isolating pile to be easily embedded into earth which exhibits high protective property of propagation of vibration in a high frequency band and a low frequency band, and also to provide a vibration-isolating wall structure with the vibration-isolating piles embedded into earth in a wall shape continuously.;SOLUTION: The vibration-isolating pile 10 has a rectangular horizontal section and has a hollow pipe 11 running in longitudinal direction, expanded resin bodies 16, 17 surrounding the hollow pipe, two structural face materials (concrete plate) 18a, 18b positioned at two opposed outer surfaces of the expanded resin body, and a reinforcement member 13(flat lattice reinforcement 14, flat shaped wire net 15) with one side welded to the hollow pipe 11 and with the other side embedded in the structural face material. An excavation bit 52 for expanding a diameter and an auger 51 are passed through the hollow pipe 11 of the vibration-isolating pile 10 and the necessary number of the vibration-isolating piles 10 is continuously embedded in the ground in a wall shape to be a vibration-isolating wall 30, and side wall surfaces are closely in contact with each other while carrying out boring 49 for and embedding of the vibration-isolating piles 10 at the same time by employing a method of pile installation by inner excavation.;COPYRIGHT: (C)2006,JPO&NCIPI
