Abstract: A live recovery storage structure for holding bulk material includes a housing having a side boundary wall with an inverted substantially U-shaped or V-shaped transverse cross section that extends between a first end wall and an opposing second end wall. The housing bounds a chamber adapted to receive bulk such that the bulk material rests against the side boundary wall. An elongated tunnel wall extends within or below the housing, the tunnel wall bounding a tunnel. At least one opening is formed on the housing so as to provide fluid communication with the chamber. A dispenser assembly is mounted on the tunnel wall so as to proved controlled fluid communication between the chamber and the tunnel.

Abstract: A method for forming a hopper in a storage structure includes mounting a form to a storage structure which bounds a compartment. The form can be flexible or rigid. A layer of cementitious material is applied over an exterior surface of the form so as to produce a rigid side wall. The rigid side wall has an interior surface bounding a progressively constricting flow channel that communicates with the compartment of the storage structure. In one embodiment, the layer of cementitious material is applied by spraying.
