Monograph Title: Prefabricated vertical drains and pavement drainage systems; Serial: Transportation Research Record; Issue Number: 1159; Publisher: Transportation Research Board; <> The reason for the change in the terminology is that PV drains do not perform any wicking process, but rather are prefabricated drains. Wick Drain has two components - a core which serves as a water conduit for a geotextile filter fabric which allows water to pass into the core while restricting the movement of soil particles which might clog the core. 21 0 obj 4 0 obj www.ceteau.com . They accelerate consolidation and settlement by an order of magnitude by significantly shortening the flow path for water to exit a soil layer (1). Therefore, in order to accelerate the settlement, the groundwater should be discharged to the outside and the soil should be compressed. This also prevents piping of fines from adjacent soils without clogging. Listing of Known Acid Mine Drainage Locations in Kentucky.
