  Application of Injection type Dredger
  Water Injection Dredging is a technique in which a specially developed Water Injection Dredger injects large volumes of water at a low pressure into the sediment,using pumps with a series of nozzles on a horizontal jet bar.
  This fluidizes the sediment by effectively overcoming the cohesion in fine-grained(cohesive)soils or internal friction of coarse-grained(granular)soils.this fluidized sediment then remains close to the river or channel bed,flowing down to deeper areas.Fluidized soil is also sometimes referred to as fluid mud,fluid bed or density cloud,but since the sediment remains just above the bed,the term“fluidized soil layer”is generally agreed to be a more apt description.
  Staying close to the bed creates a density current that then,either by the force of gravity or through a natural or artificially created slope,flows downwards to deeper water.
  This all occurs with a minimum of disturbance to the equilibrium of the ecosystem.In this way,instead of mechanical transportation,nature takes care of the sediment transport,making Water Injection Dredging under certain conditions a very cost-efficient dredging technique.
  Features of Injection type Dredger
  1)High efficiency,large output and long distance of pump
  2)Simple operation and fast assembly and disassembly
  3)Self-propulsion system,can be proposed in place when moved
  4)Good economic performance,digging and delivery of material can be completed one time.
  5)Hull consists of multiple pontoons,connected by proven coupling system.
  6)High Efficient fuel consumption and overall operating cost.
  7)Spacious and low noise operation cabin.
  8)Good access to all parts,especially the dredging pump,wearing parts and fresh water cooling system.
  9)Can be customized according to customers'requirements.
