[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 work environment has been improved.

At SEIHA in Chiba Prefecture, vibrations from trains passing near medical facilities were interfering with operations involving precision equipment in medical rooms. In response, a 'WIB method' was implemented between the railway and the medical facility. A composite WIB design was created by utilizing existing underground vibration isolation walls, combining wall-like and slab-like structures. 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 implemented, 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-like WIB + Slab-like WIB ■ Construction Position: Vibration propagation path *For more details, please refer to the PDF document or feel free to contact us.
