WICK DRAIN INSTALLATION MACHINE
WD 28 – 43

Bottom Driven “Wick Drain Installation Machine”

OMS Wick Drain Installation Machine is a soil improvement machine that to be used for quick consolidation of the cohesive soils. The machine is consisting of; hydromotors, sprocket gears, mandrel and a high frequency vibro hammer. It is very usefull equipment to drain the water in the cohesive soils, thus, the liquefaction risk minimal and settlement time higher then standard procedures.

Operation Procedure
The hydromotor driven sprocket gears insert the mandrel with Prefabricated Vertical Drain (PVD) in to the cohesive soil until the hard formation. The operator can use the high frequency vibro hammer if necessary to insert the mandrel deeper. The mandrel insert the Prefabricated Vertical Drain up to desired depth and drain stays in the soil then empty mandrel pull out and re-fill with PVD and insertion process starts again.

Advantages

  • To prevent excessive settlement of cohesive soils when it is being utilised for construction purposes (roads, airports, bridge and other foundations),
  • To enhance the soil stiffness in order to prevent liquefaction and subsequent damage to structures in seismic – sensitive regions,
  • To succeed the project in a short time and low cost.
