4 Sediment handling corruption measures related to river restoration project

Currently four ongoing river restoration project in the government during dredging operations at General aggregates (sand, gravel) can be used, but it is most often judged by some sectors that the extreme part of or contamination in estuaries (eg, cod Kumho) decayed Disc ussions are expected to cause sedimentation

These deposits will not be used as an aggregate, as well as the long-term storage and is expected to occur at the stench of waste disposal ground is not easy relationship promote all four river restoration project is expected to be an obstacle.
(Some water with clay, the same phenomenon Chidori) Accordingly, we find a solution, such as attachment materials were.

  • Attachments: 1. Overview of water treatment systems bupaeto and clay
  • Attachment 2. Dredge Slurry Separation System
  • Attachment 3. Dredging [8010 HP Versi-Dredge]
  • Attachment 4. Ohtakbangjisiseol

Project The expected completion problems and solutions

4 Guidelines for Project Quantity to secure promotion, is to install a Submerged Weir. Over time, the sediment builds up again, and soon deteriorated water quality issue is expected
to appear.

To solve this problem, we use a small Dredge Equipment Slurry separator system for regular dredging operations and the water quality deterioration can be prevented by management and improvement of water quality is expected.
