ACCELERATION OF

CONSOLIDATION

The problem of the soft cohesive clays is its very slow consolidation which often requires years to achieve.

One of new technology that has been widely implemented is the insertion of vertical wick drain. Vertical wick drain makes the consolidation process become faster. This material provides vertical lane to dissipate excess pore water pressure from subsoil. The principal of vertical drain performance are:

  • Shorten drainage path; the path is horizontal into vertical drain material.

  • Benefiting from the soil’s better horizontal permeability.

BENEFITS

  • The size of material is relatively small, therefore the disturbance effect becomes minimum

  • This material is uniform in its property because it is prefabricated

  • Flexible, since the water flow isn’t disturbed if lateral movement occurred
