Outline of Final Research Achievements

This research proposes leachate control technology using H-H joint interior space as a part of steel pile sheet pipe cutoff walls in coastal landfill site from a long-term perspective. In addition, the containment and remediation performance of the H-H joint in landfill site was evaluated by seepage and advec-tion/dispersion analysis. The H-H joint was able to perform the containment and the remediation func-tions by keeping the low water-level at H-H joints interior space. Moreover, the leachate control technol-ogy using H-H joint interior space demonstrates it’s possible to contain water-soluble toxic substances in landfill sites and remediate them.
