WICK ASSEMBLY AND METHOD FOR INSTALLING AN UNDERDRAIN |
摘要 |
A wick assembly for installation under a roadway according to the invention includes a perforated drain pipe, an inner sheet of a wicking fabric disposed on the perforated drain pipe in a manner effective to cover the perforations therein, an outer sheet of a wicking fabric, and a layer of filter aggregates confined between the inner and outer wicking fabric sheets to form a wick drain in combination with the perforated drain pipe. Water passes through the sheets and filter aggregates in order to enter the perforated drain pipe through the perforations therein. The wick drain may be disposed inside an outer pipe with the outer fabric sheet in slidable contact with the inner periphery of the pipe casing. The outer pipe casing serves to protect the wick drain during installation and is later removed once the wick drain is in position. |
