  • WICK DRAIN SHOE SYSTEMS AND METHODS
    Publication number: 20220025602
    Abstract: A wick drain shoe is configured to be connected to a free end of a length of wick drain material and driven by a mandrel of a wick drain insertion system. The wick drain shoe comprises a base portion and an extension portion secured to the base portion to define first and second shoe openings, an anchor portion, and a bearing portion. The wick drain material is connected to the wick drain shoe by inserting the free end through the first and second shoe openings such that the anchor portion and bearing portion engage the wick drain material when the wick drain material is under tension. The base portion is sized and dimensioned to engage the mandrel such that displacement of the mandrel in a first direction causes displacement of the wick drain shoe in the first direction.
