• VERTICAL sand drains, or sand piles as they are sometimes called, have been more and more widely used in recent years. They represent an attempt to augment the consolidation of unstable sat urated soils by providing vertical drain age outlets for the water presumed to be squeezed from the soil by the weight of the surcharge or fill.

The typical design parameters for the sand drains along with its permissible values are given as : (i) Diameter of sand drains ( ɸd) = 450 mm to 600 mm. (ii) Spacing between two adjacent sand drains ( S) = 1.8 m to 5 m cc (centre to centre). (iii) Depth of sand drains ( H) = 3 m to 35 m. (iv) Thickness of sand blanket = 0.6 m to 1 m.
Pattern of Sand Drains. The drains are laid either in a Square Pattern or Triangular Pattern. The spacing of drains is kept smaller than the thickness of the embankment in order to reduce the length of the radial drainage path. The zone of influence of each drain in a triangular pattern is hexagonal in plan. Similarly, the zone of influence of ...
