Sediment dredging and containment system in bottom outlets and intakes in dams

This system, patented under the brand name “Dracon®” enables the level of openings to be reached practically independent of silting due to settled mud and for it to be kept open for as long as the works last.

The Dracon® dredging and containment system is made up of the following main elements:

  • Drill head
  • Isolation modules
  • Hoisting equipment
  • Sludge evacuation equipment

INHISA designs the Dracon® sediment dredging and containment system according to the following principles:

  • Ensuring isolation of the pipeline
  • Creating a safe space for underwater work
  • Reducing the environmental impact
  • Permitting isolation, plugging and maintenance activities for intakes and bottom outlets in dams
