[WIB Construction Method Case Study] Railway Vibration Countermeasures for Residential Areas Along Railways H29.2-3

Keep the vibration level below 60dB! To ensure greater vibration reduction, measures will be implemented directly beneath unused land!

A portion of a residential development site in Saitama Prefecture faces a railway, raising concerns about the impact on the living environment after the construction of homes. Therefore, the "WIB method" was implemented directly beneath the residences. Additionally, to ensure greater vibration reduction, countermeasures were also installed directly beneath the unused land. Vibration measurements were conducted before and after the countermeasures, resulting in a reduction of dominant vibrations in the 10-20Hz range by 10-14dB (to 1/5 to 1/3 of the original vibrations), keeping the vibration level below 60dB. [Case Overview] ■ Location: Saitama Prefecture ■ Client: Housing manufacturer ■ Vibration source: Railway vibrations ■ Preservation target: Residential buildings along the railway (a total of 4 buildings + unused land) ■ Countermeasures: Plate-type WIB method (directly beneath residences) and wall-type WIB method (directly beneath unused land) honeycomb cell type ■ Installation position: Directly beneath the receiving side (beneath residences) and along the propagation path (beneath unused land) *For more details, please refer to the PDF document or feel free to contact us.
