Abstract
Soft soils with high clay content pose problems for any construction. Such soils have a tendency to entrap water and take a long time to settle. The remedy lies in quick dissipation of pore water held back within pores through a guided straight path. This was earlier used to be done through vertical sand drains. Prefabricated vertical drain (PVD) made of contiguous polymeric micro-channels under a sheath provides vertical drainage paths accelerating pore water dissipation.
Prefabricated vertical jute drain (PVJD) is a new development that functions through its coir wicks and jute sheath for draining out water vertically and also in radial direction. Initial laboratory findings conducted on PVJD are very encouraging and are comparable to PVDs. PVJD is a worth trying option for consolidating soft soils.
This chapter discusses in depth the construction of PVJD and presents a short comparative analysis of PVD and PVJD. Specifications for PVJD and preliminary laboratory findings on performance of PVJD conducted by the University of Wollongong, Australia, have also been indicated in this chapter.
