Abstract: An anchoring assembly and related system and method for facilitating the securing a holding strap to a storage tank and holding of the latter to the ground, comprising a base that is connectable to a top surface of the storage tank and an anchor that is reversibly secured to the base and positionable in a transverse direction of the storage tank to anchor a proximal end of the holding strap. The anchor includes a tightening mechanism being supported above the top surface of the storage tank by the base, wherein the tightening mechanism is actuable to move the anchor with respect to the top surface of the storage tank, thereby modifying a tension of the holding strap.

Abstract: An anchor assembly and related system for holding an underground tank below a ground level, including a lightweight anchor base defining a slot, and a retention mechanism that is locatable at multiple locations along the slot of the anchor base to securely maintain a strap assembly in place. The system can include the anchor assembly and the strap assembly, with the retention mechanism of the anchor assembly being movable along the slot of the anchor base to facilitate placement and adjustment of the strap assembly with respect to the anchor base.

Abstract: A liftable electrolytic vessel including at least one anchor assembly being at least partially embedded in each of two opposed core walls to provide anchorage to a lifting accessory of a lifting device; and related method for lifting the electrolytic vessel. Each anchor assembly comprises an anchor having a strap slot, and a strap connected to the anchor and extending from the anchor along and inside at least a portion of the corresponding core wall. The anchor further includes a connector which is sized and configured to receive a fastener or engage a lifting accessory such as a chain or a hook. The anchor assembly may include one anchor provided at each end of the strap. A plurality of anchor assemblies may extend vertically and horizontally within a core of the vessel to offer various anchorage points from an outer surface of the core. Design of the anchor of a first anchor assembly may differ from the design of a second anchor assembly. A lifting accessory is further designed to be securable to each anchor of the vessel.

Abstract: Various anchors and methods for anchoring an underground storage tank are provided. The anchor includes a base and at least one retention mechanism connected to the base for retaining various configurations of hooks and straps for holding the tank. The retention mechanism includes an opening and a retention member that is configured to open or close the opening by displacing or collapsing said retention member. The anchor may include a composite base having a footing and a spine extending upwardly from the footing so as to define footing portions on either side of the spine. The footing and the spine may have a composite composition that includes a matrix material and a reinforcement structure embedded within the matrix material. The retention mechanism may be connected to the spine of the composite base for retaining a hook for anchoring the underground storage tank.
