Prefabricated Vertical Drain manufacturer in China

As more and more land gets used for urban and industrial development, land with good foundation properties become very rare and hence increasing need is felt for various types of constructions in low and reclaimed land and coastal areas which are not suitable for normal foundations. This type of reclaimed and newly developed land is not suitable for new construction and infrastructure development especially due to the following reasons.

Low Strength
Very High Liquid Limit and High compressibility
Poor Volume Stability
Susceptibility for Liquefaction
Detrimental Physical and Chemical Changes
Hence the virgin land developed by reclamation through dredging and by filling low lying marshy and pond areas, require extensive ground improvement to strengthen the soil and to make it eligible for supporting the heavy traffic loads of Highways, Runways ,Multistoried buildings and other types of new infrastructure loads proposed to be built in this newly developed land.

Following ground treatment techniques are available which may meet the twin objectives of increasing the bearing capacity with simultaneous reduction of settlement.

Sand Drains
Stone Column
Pre fabricated Vertical Drains (PVD)
In this paper, Material Specifications, Design aspects and Installation procedures of Prefabricated Vertical Drains (PVD) have been dealt with in details for making the reclaimed land eligible for construction.
