DRAINAGE
OF
SUB-SOIL
WATER
THROUGH
VERTICAL
DRAIN |
|
|
|
Where applicable
After filling a low or marshy land the consolidation process is
accelerated with the help of Vertical Drains by drainage of excess
water.
It is also applied for quick consolidation of reclaimed areas from sea
and other water bodies, where deep seated pore water creates problem for
construction work
Why applied
Natural consolidation of a filled land is a long drawn process for
construction of a super structure on it. The process of consolidation is
quickened with the help of the drains. Instead of a few years
consolidation may take place in a few months depending on the site
condition and discharge capacity of the drains

How to apply
One end of the drain is inserted into the soil up to the water level
mechanically and the other end is cut leaving about 0.5 m above the
ground level. The insertion is carried out at regular interval depending
on the site condition. Extra load is also applied on the surface if
necessary. The water under pressure rushes through the drain after
filtration and comes to the surface |
