Steel Sheet Piles

Japan Iron and Steel Federation – All Regions

Earthquake resistance measures of embankment structure on liquefying soil foundation

---

Characteristics

• Embankment structures slip and collapse, sink, crack or change in other ways if the foundation liquefies.
• Steel sheet piles are installed by driving them deep into non-liquefying soil layer at locations near the foot of the slope of embankment on liquefying soil foundation.
• Driving high-quality steel sheet piles at the foot of embankment declining in foundation rigidity control the deformation of liquefying soil foundation and collapse of embankment structures.

 

1. Ease of work at narrow construction space
   • Work with steel sheet piles minimises the required work width compared with soil improvement method.
   • Work is fast and easy even in narrow space.
   •  Work is possible while the facilities such as railway are in operation.
2. Environment-friendliness
   • Without producing industrial waste
   • Low-vibration and low-noise work can be applied.
   • Setting the hole for seepage at steel sheet piles can avoid influence of groundwater cutoff.
3. Reduction of construction cost and period.
   • Construction cost and period can be reduced by applying steel materials.
