Method of assembling and disassembling a storage tank

摘要

A liquid containment wall for a tank is formed by corrugated panels connected end to end and supported by upstanding brackets at spaced positions around the peripheral wall and a liner attached to the wall. Each panel has at each end an overlapping section with an array of aligned holes. The holes are connected by connector plates shaped and arranged to overlie a part of the array. Each plate has a plurality of shear pegs extending at right angles and at least one hole therethrough to receive a threaded bolt so that the bolt passes through a respective one of the aligned holes of the array to clamp the plate against the overlapping panels.

1. A method for assembly and disassembly of a containment wall of a tank comprising:
providing a plurality of panels, each having a top edge, a bottom edge, an inner surface, an outer surface, a first end and a second end such that the panels can be arranged with the first end of one connected to the second end of a second to form a peripheral ring of panels surrounding an area to contain a liquid; providing on each panel at each end an end section for connection to a next adjacent panel, each end section of the panel containing an array of holes; providing a plurality of connector plates; each connector plate being shaped and arranged to overlie a part only of the array of holes so that said plurality of the connector plates is arranged on the array of holes with each of the connector plates cooperating with a respective part of the array of holes; attaching the connector plates to the end section of one panel so as to couple the end section of said one panel to an end section of a next adjacent panel; each connector plate having a plurality of shear pegs attached to the connector plate so as to extend at right angles thereto, the shear pegs being arranged in an array so that the shear pegs are aligned with respective ones of the holes of the array, the shear pegs having no fastening elements; assembling the panels by connecting each end section of the panels to an end section of a next adjacent panel by inserting the shear pegs of each connector plate through the respective holes of the array; assembling the panels by fastening each connector plate to the end section of a panel by at least one threaded fastener, separate from the shear pegs, which threaded fastener comprises a male threaded member which extends through the connector plate and through the panel and is held in place by a cooperating female threaded member to clamp the connector plate against the end section of the panel so that the shear pegs are held in place extending through the respective holes by the threaded fastener, and disassembling the panels by releasing said male threaded member of said at least one threaded fastener from its cooperating female threaded member to release the connector plate from being clamped against the end section of the panel so that, with said the connector plate being released from being clamped against the end section of the panel, the shear pegs are free to be pulled from the respective holes to release the connector plate from the end section of the panel.
