COMBINED WICK POWER!
Prefabricated Vertical Drain (PVD) Installation Equipment

- STRONG GEAR DRIVER UNIT installs the PVD material into the soil.
- VIBRO HAMMER reduces the resistance of the ground with vibration.

The OMS Wick Drain Installation Machine is a soil improvement machine that is used for the quick consolidation of cohesive soils. The machine is consisting of; hydromotors, sprocket gears, a mandrel and a high frequency vibro hammer. It is very useful equipment to drain the water in the cohesive soils, thus, the liquefaction risk is minimal and settlement time is faster than standard procedures.
The difficulties experienced by engineers in the design of structures built on loose and liquid soils have necessitated various improvement methods throughout history. Unpredictable long-term ground settlements cause unnecessary labor and additional costs, as well as a waste of time.
Simple and ordinary ground consolidation works can take quite a long time. This waste of time can be overcome by creating artificial vertical drainage paths through which water flow can be achieved.

The driving and extracting force of the Wick Drain machine is 276 kN, and the combined force (wick drain + vibro hammer) is 711 kN. Related to the enormous static and dynamic force, the machine is stronger and drives deeper. Depending on the soil condition, the machine is faster due to the operation of the mandrel and its speed up to 100 m/min.

Wick drain can be applied in all areas requiring ground consolidation, including the following areas;
- Highway walls, embankments, impoundment,
- Bridge roads, routes and crossings,
- Dams,
- Railroads,
- Airports and harbors, ports,
- Storage tanks,
- Mining waste ponds.

- Wick drains in rolls are installed in the drain drum located on the machine.
- Sand, gravel, or suitable materials are also called drain blankets shortly, are laid on the ground to be placed in the wick drain.
- The system is rigged to a vertical position with the help of an excavator. The product is ready for operation.
- The specially designed button type mandrel is driven to the desired depth by the OMS Wick Drain Installation Machine.
- After installing the mandrel, PVD material leaves into the ground.
- This operation is repeated at each predetermined drainage. In different areas of application, the depth at which the operation should be performed may vary.
- After the installation of all the drains is completed, the ground should be loaded with earth material required by the project.
- The groundwater rises to the surface through the drains.
