Japan Iron and Steel Federation – All Regions

Reinforcing existing caissons by installing steel pipe sheet piles and other steel materials in front or back side of them.


  1. Outstanding seismic resistance
    Seismic resistance is enhanced, controlling liquefaction damage.
    Installing steel materials in the front face of the caisson can prevent scouring by tsunami or waves.
  2. Efficient reinforcement
    The retrofitting can also add the depth of piers besides the resistance.


There are several track records in Japan (Kobe port etc.)
