[WIB Construction Method Case Study] Vibration Control Measures for Medical Facilities

Filling tire shred with high damping material between the underground vibration barrier and the improved column row! A case where the working environment has been improved.

At SEIHA located in Chiba Prefecture, vibrations from trains passing near medical facilities were interfering with operations involving precision equipment inside the medical rooms. In response, a 'WIB method' was implemented between the railway and the medical facility. Utilizing existing underground vibration isolation walls, a composite WIB design combining wall-shaped and slab-shaped structures was developed. Based on the micro-vibration tolerance curve for precision equipment, target vibration reduction amounts and target reduction frequency bands were established. After the measures were taken, vibrations in the target reduction frequency band were reduced to less than half, improving the operational environment. 【Case Summary】 ■ Location: Chiba Prefecture ■ Client: SEIHA Co., Ltd. ■ Vibration Source: Railway vibrations ■ Preservation Target: Precision equipment in medical facilities ■ Countermeasure Work: Wall-shaped WIB + Slab-shaped WIB ■ Installation Position: Vibration propagation path *For more details, please refer to the PDF document or feel free to contact us.
