Abstract
Abstract An improved storage apparatus for dry material in bulk is disclosed. The storage apparatus includes a tarpaulin cover and a circular metal wall. The tarpaulin cover is secured to the circular metal wall, or to any suitable surface, by a lashing means including a plurality of eyelets in the periphery of the tarpaulin cover, a plurality of anchors attached to the wall or, alternatively, to any suitable surface, a first cable attached to the anchors so as to encircle the wall, and a second cable alternately threaded through the eyelets and around the first cable. According to another embodiment there is provided a storage container which includes a flexible membrane cover and a flexible membrane base. Alternatively, the flexible membrane cover is provided separately for a pile of dry material in bulk. In these embodiments the flexible membrane cover is secured to any suitable surface utilizing the lashing means described above.
