BRAND NAME
prefabricated vertical drain wick drain for construction project
soil improvement
1.The core boards are made of mixture from PP and PE, so it
combines the rigidity of PP and the flexible and weather-resistant.
capabilities of PE.
2.Filtration membrane is made of non-woven fabrics, permeability
and water logging ability enjoying good.
3.Filtration membrane are firm together when wrapping the core
board by ultrasound.
Prefabricated Vertical Drain (PVD) is a composite product of
plastic strip with outer nonwoven geotextile layer. PVD gets
excellent physical, mechanical & hydraulic performance, which make
it an effective solution of Soft Ground Improvement to accelerate
construction and reduce both time and magnitude of
postconstruction settlement.

HOW TO USE
Wick drains are installed with specialized equipment, called
stitchers. The stitchers, which are mounted on either backhoes or
excavator consist of a vertical mast housing a special installation
mandrel. The mandrel, containing the wick drain, is hydraulically
pushed or vibrated into the ground to the desired treatment depth,
typically to the bottom of the soft-soil stratum. As the mandrel is
withdrawn back into the mast, the undamaged wick drain is left in
place within the soil mass.
APPLICATION
Wick drain projects have included dams, large storage areas,
highway embankments, sedimentation ponds, tanks, bridge abutments,
buildings, and airport runways.
The most common application of wick drains is for accelerating the
settlement rate of compressible soils. At some sites, the primary
purpose of wick drains is to increase the shear strength of
underlying soft soils. As soil consolidates, the shear strength
increases due to a reduction in the water content. This application
is particularly important when high area fills have to be placed
over soft soils with low shear strength. Potential instability
problems can be overcome by loading the site in stages and allowing
the soft soils to gain in strength under each stage before
placement of the next stage of fill.
