Large-capacity modular holding container and related methods

1. A holding container including a load-bearing wall extending around a perimeter of at least one storage area, the holding container comprising:

a plurality of pre-formed, releasably interlocking, load-bearing flat panels configured to form the load-bearing wall, each panel configured to be bent to form a portion of the load-bearing wall and wherein each panel is configured to at least partially overlap with an adjacent panel when forming the portion of the load-bearing wall,

wherein the load-bearing wall is at least partially curved, and

wherein each panel comprises at least one lip having a lip thickness less than a main body thickness of a respective panel and the at least one lip is configured to overlap with at least one lip of an adjacent panel to form an overlapped lip thickness substantially equal to the main body thickness of the panel, wherein each lip comprises at least one receptacle and, when two panels overlap, a receptacle of each panel aligns with a respective receptacle of the adjacent panel and the aligned receptacles are configured to receive a panel connector to fixedly couple the two panels together.

2. The holding container of claim 1 , wherein:

the load-bearing wall is a continuous wall, the shape of the continuous wall including at least three distinct, at least partially linear, sides and a corner between each side, and

at least one of the corners is curvilinear.

3. The holding container of claim 1 , wherein each panel is elastic and able to flex into a curved shape during use of the holding container.

4. The holding container of claim 1 , wherein:

the load-bearing wall and the at least one storage area are buried at least partially underground, and

the material composition of the panels renders the panels resistant to microbial and biological degradation and degradation due to the alkalinity of the earth.

5. The holding container of claim 1 , wherein:

when the panels are interlocked, each panel overlaps each adjacent panel across at least 5% of the smaller of its width and length.

6. The holding container of claim 1 , wherein the panels are configured to be coupled together in a manner that allows each panel to move side-to-side and up-and-down at least one of independently and in unison with one or more other panels in response to at least one of variations in a substrate below the panels and loads applied to the panels by contents of the at least one storage area without damaging or disengaging the panels or degrading the strength characteristics of the panels or the ability of the holding container to contain the contents of the at least one storage area.

7. The holding container of claim 1 , further including:

at least one liquid-impermeable surface disposed at least partially around the at least one storage area inside the load-bearing wall and configured to prevent the contents of the at least one storage area from escaping out of the holding container,

wherein the at least one liquid-impermeable surface includes at least one among the group consisting of one or more liners, geotextiles, coatings, and spongy materials.

8. The holding container of claim 7 , wherein:

when the panels are interlocked to form the load-bearing wall, at least one joint is formed between adjacent interlocked panels, and

the at least one liquid-impermeable surface extends only along the formed joints on the inside of the load-bearing wall.

9. The holding container of claim 1 , wherein:

the holding container is configured to be installed at a container installation site, and

the size of the holding container is configured to be variable during installation thereof at the container installation site in increments of one or more panels.

10. The holding container of claim 1 , wherein the panels are at least partially hollow.

11. The holding container of claim 1 , wherein the panels are configured to be modular and reusable to form at least one of partially curved, load-bearing, holding container walls having different sizes and containment capacities and holding containers having different sizes and containment capacities.
