The disclosure relates to a support such as a soil-supported post having a chisel-like end and stabilizing fins angularly disposed relative to the chisel-like end. A ribbed frusto-conical portion is connected to the post and readily permits entry thereof into the ground but resists removal therefrom as well as twisting therein. The post includes water storage means for preventing over saturation of adjacent soil and for providing moisture thereto when said soil is too dry.
An anchorage device for use in sand or sandy soils. The device comprises a shank portion (2) and a spike portion (4) at a lower end of the shank portion. The spike portion (4) comprises a first and second pair of downwardly convergent plates (6,18), the second pair of plates (18) extending from a position above the upper ends of the first plates (6) to a position beneath the upper ends of the first plates to funnel sand into the zone between the interior surfaces of the first plates (6). The sand thereby trapped between the plates anchors the spike portion (4) within the ground. The device may be used for example for anchoring beach umbrellas, tents and fences in sand or sandy soil.
