A containment system comprising a flexible bladder having at least one opening through which a liquid or other fluid or material can be pumped or transferred into or out of the bladder. The bladder has a contracted and an expanded or semi-expanded state. A support structure surrounds the side surfaces of the bladder and provides lateral support to the bladder when the bladder is in an expanded or semi-expanded state. The support structure comprises a plurality of panels that are seperably connected to one another to form an enclosed walled support structure. The at least one opening in the bladder is operatively connected to a point exterior to the support structure to permit the bladder to be filled or evacuated from a position exterior to the support structure.

The present invention is directed generally to a demountable silo (10) comprising a series of interconnected silo modules (12A to 12F) constructed in accordance with a preferred embodiment of this invention. The silo modules such as (12A) are each of a substantially identical configuration and interconnected in a side-by-side and end-to-end relationship. The demountable silo (10) is designed to contain particulate material and configured depending on the nature of the material and its storage requirements. It will be appreciated that the provision of multiple silo modules such as (12A to 12F) together contains significantly more particulate material in a heap than a single silo module. The maximum storage capacity for the demountable silo (10) is determined largely by the angle of repose of the heaped particulate material.

A proppant discharge system has a container with an outlet formed at a bottom thereof and a gate slidably affixed at the outlet so as to be movable between a first position covering the outlet to a second position opening the outlet, and a support structure having an actuator thereon. The container is removably positioned on the top surface of the support structure. The actuator is engageable with gate so as to move the gate from the first position to the second position. A conveyor underlies the container so as to receive proppant as discharged from the container through the outlet. The container is a ten foot ISO container.

A modular portable storage container system includes container sections, each having a frame. A latch mechanism retains the frames against an infrastructure substrate. The latch mechanism has: a spring latch, latch receiver, and retaining hook. The container sections are movable between unlatched and latched positions. When unlatched, the container sections are movable relative to the substrate and when latched the frames of the container sections are retained in contact with mounting points of the substrate via the latch mechanism. The spring latch and the latch engage one another when the container sections are in the latched position, and the retaining hook engages with the frame to rotatably retain the frame. The spring latch and retaining hook include mounting flanges that are selectively slidably and fixedly mountable to mounting points of the infrastructure substrate in one or more positions defined by a size of the container sections.

A corrugated storage container is provided that includes a box section with a top wall and corrugated side walls and end walls, a tapered funnel section extending downwardly from the box section and a frame supporting the box section and the funnel section. The frame includes vertical posts that are integrally joined with the box section and a base section formed at the lower end of the vertical posts and supporting the funnel section. The configuration of the corrugated storage container provides approximately 600 cubic feet of enclosed interior volume capable of storing between 50,000 and 51,000 pounds of bulk material.
