Liquefaction countermeasure WIB method

Reduction of seismic forces and prevention of liquefaction! Constraining the soil inside the cell to suppress ground deformation and reduce seismic motion.

The "Liquefaction Countermeasure WIB Method" protects buildings from damage caused by earthquakes and liquefaction. The basic structure consists of replacement soil that acts as a seismic isolation layer, ground improvement piles that function as a damping layer, and support ground improvement piles that support the building foundation. The ground improvement piles in the damping layer are constructed in a cellular form, creating a strong and stable composite ground (non-liquefaction layer). Additionally, by increasing resistance through the combination of pile foundations and the WIB method, it is possible to reduce the number of piles or lower the grade of the piles, thereby rationalizing the design and contributing to cost reduction. 【Features】 ■ Ground improvement piles in the damping layer are constructed in a cellular form ■ Creates a strong and stable composite ground (non-liquefaction layer) ■ During an earthquake, the cellular ground improvement piles restrain the soil inside the cells ■ Suppresses ground distortion and reduces seismic motion ■ Since liquefaction does not occur inside the cells, it blocks the propagation of liquefied mud water below, preventing surface liquefaction *For more details, please refer to the PDF materials or feel free to contact us.
