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.
- 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.
- 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.
- Reduction of construction cost and period.
- Construction cost and period can be reduced by applying steel materials.
