Abstract

The invention described herein includes materials and methods for segmental wick drain installation for versatile groundwater management. The invention comprises modified mandrels that may be coupled together for segmental installation wick drain installations to desired depths that are not achievable using currently known methods. Each modified mandrel is configured with a shoe coupler that may be permanently affixed to one end and configured with a means for securing the shoe coupler to a modified end of another mandrel. Each shoe coupler includes transverse bore holes through which set pins may be inserted that engage with an end of another modified mandrel with grooves corresponding to the locations of the bore holes when set pins are inserted. Once the wick drain is installed to the desired depth, the mandrels may be extracted and uncoupled by removing the set pins. The modified mandrels may be prefabricated and reused, ideal for multiple installations.
