Liquefaction countermeasure WIB method

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.

Different subsidence countermeasures

Different subsidence countermeasures

The safety of the building has improved! Strengthening the ground serves as a foothold for suppressing differential settlement.

Differential settlement refers to the uneven application of the building's load on the ground, causing the building to tilt. When differential settlement occurs, it can lead to various issues in daily life, such as doors and windows not closing properly and health problems. By constructing a WIB structure within the ground, the rigidity of the WIB structure distributes the load into the ground, resulting in a structural form that increases the bearing capacity against the building load beyond the strength of the original ground at ultimate bearing capacity. Since the WIB structure is built with a planar spread, it can be designed to evenly distribute the loads from buildings and other structures. As a result, it can suppress differential settlement of the ground and improve the safety of the building. 【Features】 ■ Strengthening the ground serves as a foothold for suppressing differential settlement. ■ Designed to evenly distribute the loads from buildings and other structures. ■ Can suppress differential settlement of the ground and improve building safety. *For more details, please refer to the PDF materials or feel free to contact us.

Some plots of a residential development in Saitama Prefecture face a railway, raising concerns about the impact on the living environment after the construction of the houses. Therefore, the 'WIB method' was implemented directly beneath each of the residential buildings from Building A to Building E. Vibration measurements were conducted before and after the countermeasures. As a result, the dominant vibration at 10Hz was reduced by 14dB (to 1/5 of the original vibration), successfully keeping the vibration level below 60dB. [Case Overview] ■ Construction Location: Saitama Prefecture ■ Client: Housing Manufacturer ■ Vibration Source: Railway Vibration ■ Preservation Target: Residential buildings along the railway (total of 5 buildings) ■ Countermeasure Work: Plate-type WIB method (honeycomb cell type) ■ Construction Position: Directly beneath the receiving side *For more details, please refer to the PDF document or feel free to contact us.

[WIB Construction Method Case Study] Railway Vibration Countermeasures for Residential Areas Along Railways, September 2018, Saitama Prefecture

Concerns about the impact on the living environment after residential construction! Introducing examples aimed at increasing vibration reduction effects!

Some of the residential development plots in Saitama Prefecture face a railway, raising concerns about the impact on the living environment after the construction of the houses. Therefore, the 'WIB method' was implemented directly beneath the houses. In buildings D and E, where the vibration level exceeded 70dB before the measures were taken, the countermeasures were extended on the railway side to enhance the vibration reduction effect. After conducting vibration measurements before and after the measures, the dominant vibration at 10Hz was reduced by 6dB to 14dB (to 1/5 to 1/2 of the original vibration), successfully keeping the vibration level below 60dB. 【Case Summary】 ■ Location: Saitama Prefecture ■ Client: Housing manufacturer ■ Vibration source: Railway vibration ■ Preservation target: Residential buildings along the railway (total of 5 buildings) ■ Countermeasure work: Plate-type WIB (honeycomb cell type) ■ Construction position: Directly beneath the receiving side (partly on the propagation path) *For more details, please refer to the PDF document or feel free to contact us.

[WIB Construction Method Case Study] Road Traffic Vibration Mitigation for Residential Areas Along Elevated Bridges

[WIB Construction Method Case Study] Road Traffic Vibration Mitigation for Residential Areas Along Elevated Bridges

Reduced vibrations of 4Hz by about 5dB and vibrations of 12.5 to 20Hz by about 10dB! The vibrations have become such that they do not affect livability!

The planned construction site for housing in Kanagawa Prefecture was experiencing traffic vibrations transmitted from the elevated bridge and the road in front of the site. As a countermeasure, we implemented measures directly beneath the apartment building. The vibrations from the elevated bridge were predominantly at 4Hz, while those from the road in front of the site ranged from 12.5 to 20Hz. We designed the "WIB method" to address each of these vibrations. As a result, we reduced the 4Hz vibrations by approximately 5dB and the 12.5 to 20Hz vibrations by about 10dB, resulting in vibrations that did not affect livability. [Case Summary] ■ Construction Location: Kanagawa Prefecture ■ Client: Housing Manufacturer ■ Vibration Source: Road Traffic Vibration ■ Preservation Target: Apartment Building (New Construction, 3 Stories) ■ Countermeasure: Plate-type WIB Method (Honeycomb Cell Type) ■ Construction Position: Directly Beneath the Receiving Side *For more details, please refer to the PDF document or feel free to contact us.

[WIB Construction Method Case Study] Road Traffic Vibration Countermeasures for Residential Areas Along Roads

Confirmed a vibration reduction of 3-6dB on the first floor and 4-5dB on the second floor! Introducing a case where livability has improved!

In residential houses along the roads in Tokyo, vibrations from large vehicles were propagating, and vertical vibrations were affecting the living environment. Therefore, during the rebuilding of the houses, the 'WIB method' was implemented directly beneath the residences. Vibration measurements were conducted before and after the countermeasures within the buildings. As a result, a reduction of 3-6 dB on the first floor and 4-5 dB on the second floor was confirmed, improving livability. [Case Summary] ■ Location: Tokyo ■ Client: Sekisui Heim Corporation ■ Vibration Source: Road traffic vibrations ■ Preservation Target: Houses along the road ■ Countermeasure Method: Plate-type WIB (honeycomb cell type) ■ Installation Position: Directly beneath the receiving side *For more details, please refer to the PDF document or feel free to contact us.
