Abstract

“J pocket pile,” which is the steel sheet pile with a groove in the joints, has been developed to apply to a cut-off wall at wasted disposal sites. Swelled natural rubber and silicone resin were applied as sealing materials and its impermeable performance has been confirmed through the laboratory and field tests. The installation of the sealing material has also been confirmed by various field tests. Based on these results, “J pocket pile” has been applied to cut-off walls at the coastal waste disposal sites and landfill sites.
