BRAND NAME

Drainage Equipment Prefabricated Composite Vertical Drain for Soft 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 As the mandrel is withdrawn back into the mast, the undamaged wick drain is left in place within the soil mass.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.
