Abstract

A relocatable tank, and method of constructing same, have a plurality of precast wall panels retained by a cable tensioning system between a plurality of support members to form a continuous, preferably generally circular, wall. At least some of the support members comprise at least one aperture and at least one elongate slot to receive respective cables of the tensioning system to retain a shape of the tank. The tank can be easily assembled at a site with prefabricated parts and easily deconstructed when no longer needed and be relocated and reinstalled in a range of sizes if desired. The relocatable tank is typically installed on a compacted earthen pad with no requirement for a concrete footing, unless the tank is used in regions with high seismic or wind activity. A liner system comprised of either a single or double arrangement is installed to fluidly seal the tank. The inclusion of water ballast tubes means no minimum liquid level is required to secure the liner in a designated position.

Claims27

Dependent claims

A relocatable tank comprising:

a plurality of free-standing steel support members arrangeable in a spaced apart configuration along a perimeter of the tank, wherein each free-standing support member comprises an I-beam attached to a base portion, wherein the base portion of each support member is placed on a prepared earthen pad without the need for a concrete foundation;
a plurality of substantially planar precast concrete wall panels arrangeable between, and received at least partially within the plurality of support members to form a continuous wall along the perimeter of the tank;
and
a tensioning system comprising a plurality of cables configured to extend around an outside of the continuous wall;
wherein at least some of the support members comprise at least one aperture and at least one elongate slot to receive respective cables of the tensioning system to retain a shape of the tank;
wherein at least some of the support members are tensioning support members and the tensioning support members are provided in pairs periodically around the perimeter of the tank;
and
wherein the cables are passed through the apertures in the tensioning support members and retained and tensioned on one side of each of the tensioning support members in an alternating sequence.

A method of assembling a relocatable tank on a site, the method comprising the steps of:

erecting a plurality of free-standing steel support members in a spaced apart configuration along a perimeter of the tank, wherein each free-standing support member comprises an I-beam attached to a base portion and the base portion of each support member is placed on a prepared earthen pad without the need for a concrete foundation, and wherein at least some of the support members comprise at least one aperture and at least one elongate slot;
erecting a plurality of precast concrete wall panels between, and received at least partially within the plurality of support members to form a continuous wall along the perimeter of the tank;
and
substantially surrounding an outside of the continuous wall with a plurality of cables of a tensioning system received within the at least one aperture and/or the at least one elongate slot of the support members to retain a shape of the tank;
providing at least some of the support members in the form of tensioning support members in pairs periodically around the perimeter of the tank;
passing the cables through the apertures in the tensioning support members;
and
retaining and tensioning the cables on one side of each of the tensioning support members in an alternating sequence.
