A bulk storage facility for pulverulent friable or fungible material, such as coal, is disclosed having a slot defined by downwardly convergent inclined walls each of which are fabricated from a plurality of wall panels. The wall panels are the facing for a coherent mass that includes a multiplicity of thin flexible reinforcing strips that are each surrounded by particulate material. Each wall panel has an inclined surface which defines an angle with respect to a horizontal plane that exceeds the angle of repose of material to be stored in the bulk storage facility. In addition, each wall panel may be provided with a pair of gussets which extend into the particulate material positioned therebehind. Several flexible metal reinforcing strips may be attached in vertically spaced relation to each of the gussets. Each edge surface of the wall panel has a tongue and an adjacent rabbet such that, when the panels are assembled in a wall, adjacent panels interlock to restrain the panels against rotation about horizontal and vertical axes. The method of construction includes building the inclined walls by laying a first course of panels, backfilling the panels with a layer of particulate material, attaching a generally horizontal planar array of reinforcing strips to the panels, covering the planar array with a lift of particulate material; repeating the attaching and covering steps until the first course of panels is completely backfilled, placing a second course of panels on the first course with sealant material therebetween, repeating the procedure for backfilling and placing additional courses with backfilling until the wall is completed. |
