<p>A vertical prefabricated composite drain (10) for improving conventional consolidated acceleration of saturated soils. The composite drain is installed in a generally vertical manner in water saturated soil (24) to be treated for expelling pore water from the soil and is provided with an elongated core (12) with at least one channel (13) therealong for conveying fluids and is also provided with filter fabric (14) which surrounds the core. At least one elongated tube (15) is installed in juxtaposition and coextension with the drain core (12) and fluid under pressure is forced through the tube (15) for thereby assisting an expulsion of pore water from the drain (10).</p> |
