A rack rail is suspended into a silo from an opening formed in a ceiling portion of the silo and a lifting body is lowered into the silo along the rack rail from the opening. A work scaffold is built on the lifting body using a part carried into the silo from the opening, a worker connected to the work scaffold with a safety belt pokes and breaks down a granular powder in a state where a discharge port of a silo bottom portion is closed, the poked and broken down granular powder drops to a rat hole (or boring hole), the worker connected to the work scaffold with the safety belt adds a rack rail in a state where the rat hole is blocked with the granular powder, the discharge port is opened to discharge the granular powder stored in the passage, and then the work scaffold is lowered to the added rack rail.

A collapsible storage silo having an expanded configuration includes: (a) a shell for circumscribing storage space and comprising a plurality of concentrically nested tubular members that are collapsible; (b) a lift system operable to slidably expand the plurality of concentrically nested tubular members to place the silo in its expanded configuration; and (c) a mast operable to support the lift system, The mast is pivotable between horizontal and vertical positions relative to a frame. A winch attaches to the mast and a cable extends between the winch and an outermost tubular member to expand the silo such that inwardly and outwardly projecting lips of nested members engage each other and a conical hopper engages an innermost tubular member. A flexible inner liner attaches between an outermost tubular member and the hopper. A collapsible roof has a flexible roof membrane and a plurality of radially extending foldable rib members.

A subsea material delivery structure, including at least one material storage tank, wherein the material storage tank includes a rigid outer container, at least one pressure balanced inner flexible container. A pinch prevention device may be disposed within the at least one inner flexible container to prevent premature closing of a fluid egress pathway.

A method of generating feedback for a container load process includes: during a load process for a container at a load bay, controlling a sensor assembly disposed at the load bay to capture sensor data depicting an interior of the container; at a computing device connected to the sensor assembly, detecting, based on the sensor data, a wall of items placed in the container interior; determining, at the computing device from the sensor data: (i) a boundary attribute of the detected wall, and (ii) a composition attribute of the detected wall; comparing, at the computing device, (i) the boundary attribute to a boundary criterion, and (ii) the composition attribute to a composition criterion; and responsive to at least one of the boundary attribute not meeting the boundary criterion, or the composition attribute not meeting the composition attribute, generating an alert for transmission to a client computing device.

A method and apparatus for collecting agricultural manure in a confined animal feeding operation includes a separator which receives heavy manure removing particulate from suspension to produce light manure. Heavy manure is collected to a volume of heavy manure sufficient to substantially fill the first tank. Within the first tank, particulate migrates, due to the influence of gravity to form a layer containing manure comprising a lesser density of particulate than is present in the volume of heavy manure. Additional heavy manure buoys the layer such that the upper surface exceeds a height of a weir. The weir is situated in a channel communicating between the first tank and a second tank configured to receive light manure from the separator.
