the soil spreads away from the specifically shaped cast body u2014 it is cleaved to the side as shown in the arrow 60 as the soil heaving works its way incrementally downward due to the nature of freezing temperatures or moisture permeating the soil the process continues as in heave areas 51 amp 52 and the resulting sideways motions 61 amp 62 having established this pattern of movement the soil will continue to work in this way heaving away but not directly against the cast body while the pins keep the system anchored in place in this type of application it is imperative that the lower ends of the driven pins are below the frost or heaving line in order to maintain anchoring resistance also where the wedge configuration is internalized such as in the second embodiment 34 or the very center of the base of the first embodiment that the depth 70 created by the plug or wedge block used in the casting process is at least equal or greater than the estimated vertical heave displacement of a given site soil fig6 again diagramatically shows the relationships between the relative diameters of the system components where the driven piles 18 are of a constant cross section and a have a diameter x and the tapered dowels 10 have near the thinner end a diameter 10 b just larger than the pile x c and at the larger end a diameter.
