Description
Drainage Board PVD/ Wick Drain/ Prefabricated Vertical Drain Wick drain, also known as Prefabricated Vertical Drain, is a composite product of plastic strip with outer nonwoven geotextile layer. It is widely used for Soft Ground Improvement due to its excellent physical, mechanical & hydraulic properties. PVD is an effective solution for soft ground treatment in minimizing the settlement issue after construction.
Ever since the concept of Prefabricated Drainage System was introduced, it has helped to accelerate construction and reduce both time and magnitude of postconstruction settlement. Today, Prefabricated Drainage System has brought effective changes to many construction projects, highways, railways, airport, seaport and many more.
The Application of Drainage Board PVD/ Wick Drain/ Prefabricated Vertical DrainPVD is applied to reduce construction time and speed up the consolidation of soft ground for the following work: | · Bank revetment |
| · Development of seaport area |
| · Road, railway & airport construction |
| · Improvement of dredged clay fill |
| · Construction of gas & oil storage facilities |
| · Development of building & industrial complex site |
The Usuage of Drainage Board PVD/ Wick Drain/ Prefabricated Vertical DrainWick 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 As the mandrel is withdrawn back into the mast, the undamaged wick drain is left in place within the soil mass.The Specification of Drainage Board PVD/ Wick Drain/ Prefabricated Vertical Drain| PVD TECHNICAL DATA |
