Tarpaulin anchoring system
Abstract
Abstract A tarpaulin anchoring system for retaining a tarpaulin on a pile of stored grain or other granular material comprises a plurality of anchors embedded in the pile. Each anchor has an attachment element protruding upwardly from the pile, with the attachment element being connected to a fastener affixed to the underside of the tarpaulin. The anchors are placed in the grain pile, throughout the area covered by the tarpaulin, as required to retain it in place. The anchors themselves may be of a screw or auger type which can be driven into an existing grain pile and attached to a tarpaulin as it is spread over the pile. In the case where a tarp is suspended above a grain storage area prior to formation of the grain pile, the anchors may be discs or plates attached to the underside of the tarpaulin by ropes; the anchors are buried in the pile when formed.
