A holding container includes a plurality of pre-formed, releasably interlocking, load-bearing panels configured to form an at least partially curved, load-bearing wall extending around the perimeter of at least one storage area capable of containing at least 100,000 gallons of liquids, solids or a combination thereof. At least one among the width and length of each panel is less than 102 inches in a non-load-bearing state.

A vertical fluid storage tank including a body extending from a first end to a second end and including a substantially oval-shaped cross-section, a top wall connected to the first end of the body, a bottom wall connected to the second end of the body, at least one access opening positioned on the top wall configured for access to an interior cavity of the body, and at least one discharge valve connected to the body. The storage tank is configured to be arranged in at least two positions. The at least two positions include a first position in which the storage tank is arranged parallel to a surface, and a second position in which the storage tank is arranged perpendicular to the surface. A walkway may be positioned in the interior cavity of the body.

A modular fluid containment system has wall segments that are joined at angled corners to form a closed wall. A membrane spans the closed wall and is connected to the closed wall with membrane attachment members. In some embodiments, a truss may span the closed wall and support a second membrane that protects impounded liquids from the environment.

A gasket arrangement (122) for providing a substantially fluid-tight seal between at least two corresponding mating surfaces (120), comprising a first member (124) and a second member (126), the second member (126) being arranged at least in part to provide a fluid-tight seal about the first member (124); wherein the second member (126) is capable of deforming the first member (124) while maintaining the fluid-tight seal when compressed.

A vertical fluid storage tank including a body extending from a first end to a second end and including a substantially oval-shaped cross-section, a top wall connected to the first end of the body, a bottom wall connected to the second end of the body, at least one access opening positioned on the top wall configured for access to an interior cavity of the body, and at least one discharge valve connected to the body. The storage tank is configured to be arranged in at least two positions. The at least two positions include a first position in which the storage tank is arranged parallel to a surface, and a second position in which the storage tank is arranged perpendicular to the surface. A walkway may be positioned in the interior cavity of the body.

A grain storage bin includes a cylindrical wall formed by a plurality of panels arranged in rows with a bottom edge of a first row bolted to a top edge of a second lower row. At each joint the bottom edge of the first upper row is overlapped with and outside of the outer surface of top edge of the second lower row and the bottom edge is fastened to the top edge by bolts carrying spacers as to define a first channel along the joint for passage of air. A central air injection duct is formed of a series of generally frustoconical duct pieces arranged in a row suspended on a cable from the roof with a tube portion into which the air is injected fixed on legs at a hopper bottom standing upwardly therefrom. The cable is connected by a spring at the bottom to maintain tension

In an LNG tank, a dike is formed by arranging precast blocks in the circumferential direction and layering the precast blocks in the vertical direction. Each of the precast blocks has loop joints on the top, bottom, left, and right side faces, and concrete is deposited between each two precast blocks adjacent in the circumferential direction and the vertical direction, whereby masonry joints are formed in the vertical direction and the circumferential direction. Prestress is imparted to the dike by PC steel members. The PC steel members are provided in the circumferential direction and the vertical direction of the dike, and are arranged so as to avoid the masonry joints in the circumferential direction and the vertical direction. Therefore, it is possible to construct the dike in a short time, and it is possible to provide a tank or the like that can reduce the construction period.

A collection tank for mounting under a floor of a building for collecting water from an area under the floor comprises upper and lower tank portions removably securable by rotatable mating of tabs in cavities. Additionally, a pump platform of the tank is formed by a plurality of ridges which form therebetween a channel so that the water is collectable in the tank between the ridges. Furthermore, the upper and lower tank portions are separable, and a width of the top of the upper tank portion is smaller than a width of the open top of the lower tank portion such that the upper tank portion can be received in the lower tank portion in an inverted orientation, in which the collection tank is inoperable for collecting the water, so as to decrease a height of the collection tank.

The present invention relates to a silo (1) comprising one or more cells (2), each cell comprising one or more outlet openings (3), wherein said cells have an angular cross-section and wherein said outlet openings have a non-angular cross-section, wherein said outlet openings and said cells are connected to one another by means of a transition plate (4), wherein the angle a between the wall of the cell and said transition plate is constant along the radial periphery of the outlet opening. The present invention also relates to a kit and a method for constructing such silo.

A vertical fluid storage tank includes an oval-shaped body having a first end, a second end, and a sidewall extending between the first and second ends. The body defines an interior fluid storage cavity and has a major axis and a minor axis along a horizontal cross section through the body. The fluid storage tank further includes a top wall at the first end of the body, a bottom wall at the second end of the body, and a frame member connected to the sidewall of the body. The frame member includes a first portion that extends longitudinally along the sidewall of the body and a second portion that extends along the bottom wall and is connected to the first portion. The fluid storage tank further includes a connection port on the sidewall of the body adapted for connection to the connection port on an adjacent fluid storage tank.
