PURPOSE:To absorb vibrations effectively with possibly small space by a method wherein viscoelastic material is applied to one or both sides of each steel sheet pile and these piles are buried under the ground surrounding the vibration source to form the vibration shielding wall. CONSTITUTION:A plurality of steel sheet piles 3 including couplings 4, 4' at each both side ends are buried under the ground in the engaged form to provided a vibtation shielding wall 2. Viscoelastic materials 5, 5' such as asphalt are applied to both sides of each steel sheet pile 3 to cover it entirely with thickness of 5- 10mm.. When vibrations from a vibration source 1 reach to the vibration shielding wall 2, they are absorbed by the viscoelastic materials 5, 5' applied on the steel sheet piles 3 to prevent the vibrations from propagating outwards from the vibration shielding wall 2. At this occasion, the viscoelastic material may be applied only one side of each pile which is directed to the vibration source. |
