This disclosure relates to the field of support bases for containers, and more particularly, to such support bases that are reconfigurable in size.
In certain industries, portable containers, or tanks, are used for storage. These containers are transported to a job site, such as an oil rig, and then installed and commissioned for use. Typically, the ground at the physical location at which a container is to be installed is prepared, and a layer of pea gravel is placed on top of the prepared ground. The container is then placed on the pea gravel, and installed and commissioned.
The laying of the pea gravel can be labor intensive, however, as it may involve the use of various pieces of construction equipment. Moreover, the pea gravel may not adequately protect the underlying ground from leaks or spills, raising potential environmental concerns.
So as to address these limitations, advances have been made in the technology involved in the installation of such containers. For example, portable support bases constructed from multiple interlocking pieces have been developed to take the place of pea gravel in supporting the container.
While these developments represent an advance over the use of pea gravel, containers are made in a variety of sizes, and these portable support bases are each proportioned for a given sizes of above and below ground container. Thus, different portable support bases are used for differently sized containers, which may create logistical and inventory problems in terms of manufacture and transport, as well as issues with re-use of a portable support base with different above and below ground containers. In addition, in some cases, it may be desirable to protect the ground (or environment) from liquid spills or leaks, and pea gravel may not be able to provide the desired degree of protection.
Consequently, further developments in technology involved in the installation and support of above and below ground tanks are desired.
This summary is provided to introduce a selection of concepts that are further described below in the detailed description. This summary is not intended to identify key or essential features of the claimed subject matter, nor is it intended to be used as an aid in limiting the scope of the claimed subject matter.
A support base for a container includes a plurality of support base portions. Each support base portion has an outer surface defining a plurality of alignment features to facilitate alignment of each support base portion with adjacent support base portions in a plurality of configurations.
A further aspect is directed to a support base for a container that includes a plurality of support base portions. Each support base portion may include a shell having an interior portion, and may be constructed from a first material having a first degree of resistance to breakdown in the presence of hydrocarbons. The shell may have an outer surface defining at least one alignment feature to facilitate alignment of each support base with adjacent support bases in a plurality of configurations, with each configuration being sized to support a differently sized container. Filler may be disposed within the interior portion of the shell and may be constructed from a second material having a second degree of resistance to breakdown in the presence of hydrocarbons.
Another aspect is directed to a support for a container. The support may include a support base that has a plurality of adjacent support base portions, with each support base portion being equal in size and shape.

The coating may be applied via dispensing, and may be poluria, polyisocyanurate, or any suitable coating. In addition, the coating may be applied via any suitable method of applying a coating.
Yet another method aspect is directed to a method of making the support base for the container. Here, the shell may be formed by dispensing a first material, such as a suitable polymer, polyuria, polyisocyanurate, etc., into a mold. The shell may then be allowed to cure. Filler may then be disposed within the interior portion of the shell.
One or more embodiments of the present disclosure will be described below. These described embodiments are only examples of the presently disclosed techniques. Additionally, in an effort to provide a concise description, all features of an actual implementation may not be described in the specification.
When introducing elements of various embodiments of the present disclosure, the articles “a,” “an,” and “the” are intended to mean that there are one or more of the elements. The terms “comprising,” “including,” and “having” are intended to be inclusive and mean that there may be additional elements other than the listed elements. Like numbers refer to like elements throughout, and like elements in different embodiments are separated in number by century.
With initial reference to
A sample support base portion 202 is shown in
Referring again to
As stated, the first material may be resistant to breakdown in the presence of hydrocarbons, and may be a polymer (i.e. polyurethane, polyuria, polypropylene, polyethylene, polyisocyanurate, etc), wood, gypsum, cementious board, metal, or any other suitable material. The first material may be a homogenous material, or may be a heterogenous material. The first material may include multiple different constituent components, such as nested layers of different polymers. In addition, particles of other materials may be dispersed within the first material.
The second material may be a material that is less resistant to breakdown in the presence of hydrocarbons, and indeed may breakdown quickly in the presence of hydrocarbons. The second material may be a foam plastic such as expanded polystyrene or polyisocyanurate, or may be a recycled material, such as asphalt shingles, tire rubber, gypsum, polyurethane, wood, polymer, or any other suitable material. The second material may be homogenous, or may be heterogenous. The second material may include multiple different constituent components, such as foam plastic supplanted with recycled material.
Rather than the first and second materials having first and second degrees of resistance to breakdown in the presence of hydrocarbons, the first and second materials may have respective first and second properties. Thus, the first and second properties can be resistance to breakdown in the presence of hydrocarbons, and the first property can be a greater resistance to breakdown in the presence of hydrocarbons. Therefore, the first material may have a greater resistance to breakdown in the presence of hydrocarbons than the second material, and the outer shell 250 may protect the filler 254 from exposure to hydrocarbon containing fluids that may spill on the support base portion 202, or that may leak from the container.
The first and second properties may additionally or alternatively relate to resistance of the material to deformation. For example, the first material may also have a higher degree of resistance to deformation than the second material, so as to help resist deformation under the weight of the container. Thus, in some applications, the first material and second material may be equally resistant to breakdown in the presence of hydrocarbons, yet not equally resistant to deformation, and in such applications the shell serves to protect the filler from deformation, for example due to the weight of the container and its contents.
In some applications, the outer shell 250 may not fully encapsulate the filler 254, and may therefore lack a bottom portion, as shown in
In yet further applications, the outer shell 250 may fully encapsulate the filler 254, but may not be integrally formed as a monolithic unit. For example, the top portion, bottom portion, or a sidewall portion may be removable to facilitate ease of production, or to allow introduction, removal, and replacement of the filler 254. For the same reasons, in other applications, there may be an access feature, such as a door or a plug, defined in, defined by, or installed in the outer shell 254. In other applications, the filler 254 may be pre-sized for the support base portion 202, with encapsulation of the filler 254 being performed by spraying or otherwise applying coating or shell to the filler 254, where such coating or shell may comprise polyurethane, polyuria, polypropylene, polyethylene, polyisocyanurate, etc.
Although the support base portions 102 shown in
The support base portions 302 may be shaped such that when they are aligned in a configuration where each support base portion 302 is in contact with adjacent base portions, the support base 300 represents a continuous surface with a central hole 310 about the center point, as shown in
The outer surface of the outer shell 250 may define drainage passageways 255, as shown in
The outer surface of the outer shell 250 may define at least one drainage groove 220, as also shown in
Referring again to
For example, the configuration shown in
The alignment features 104, as shown in
In some applications, the alignment features 304 may be a semicircular grooves defined by the outer surface of the shell of the support base portions 302, as shown in
Referring again to
To maintain alignment between each support base 102, and to maintain a desired constant distance between each support base 102, an alignment apparatus or apparatuses 103 are inserted into selected ones of the alignment features 104 of adjacent support bases 102. As shown, since each support base 102 has a same size and shape, the alignment apparatuses 103 may be symmetrical, and are inserted into corresponding alignment features 104
Each alignment apparatus 103 may be a dog bone shaped member, such as a member having a first portion with a second portion extending therefrom. A sample dog bone shaped member 403 is shown in
The dog bone shaped member 403 may be universal. In some cases, the dog bone shaped member 403 may be adjustable, for example via the medial portion being adjustable in length. For example the medial portion could be telescoping, or could be comprised of two threadingly connected members. Additionally or alternatively, the medial portion and end caps may be removable, such that different length medial portions may be used with the same end caps. Furthermore, in some applications, it may be useful for different sized end caps to be used.
The dog bone shaped member 403 or any such alignment apparatus may be constructed from suitable rigid materials, such as metal, plastic, or wood. It may be monolithically formed as an integral unit, or, as explained above, may be assembled from multiple subcomponents.
Referring again to
Each alignment apparatus 103 may have a same size and shape, or, may not have a same size and shape. For example, different length dog bone shaped alignment apparatuses 103 may be used in certain alignment features 104 in some applications. The different length dog bone shaped alignment apparatuses 103 may be used in a same application, or may be used in mutually exclusive applications such that the choice of dog bone length selects the size of the support base 100 formed by the support base portions 102. For example, dog bone shaped alignment apparatuses 103 of a first length may be inserted into given alignment features 104 of the support base portions 102 so as to configure the support base portions 102 to form a support base 100 of a first size, while dog bone shaped alignment apparatuses 103 of a second length may be inserted into the given alignment features 104 of the support base portions 102 so as to configure the support base portions 102 to form a support base 100 of a second size.
Similarly, same size and shape alignment apparatuses 103 may be used to form a variety of configurations of the support base 100 by moving the alignment apparatuses 103 from one alignment feature 104 to another. This is perhaps best illustrated in
In some applications, particularly those where the support base 300 is in a large diameter configuration, the alignment apparatus 303 may also act as, or be, support members to help distribute the weight of the tank over the support base 300. In such application, it is advantageous for the alignment apparatus 303 to be flush with the top surface of the support base 300, as opposed to being recessed.
Although a ring shaped alignment apparatus 303 (
Construction of the support base portions 102 will now be discussed. The outer shell of each support base portion 102 is formed from the first material via injection molding, rotary molding, blow molding, vacuum forming, and/or any other suitable technique. The filler is then disposed within the interior portion of the outer shell of each support base portion 102 by pouring the filler into the interior portion, dispensing the filler into the interior portion (i.e., by spraying, etc), and/or any other suitable technique.
In some applications, the outer shell of each support base portion 102 may be formed around the filler. In addition, it should be understood that the outer shell of each support base portion 102 may be formed, and then the filler disposed therein at a later point in time, so as to allow easy shipping and handling of each support base portion 102.
In other applications, the outer shell of each support base portion 102 is formed from the first material by dispensing the first material into a reusable mold, such as by spraying. The filler is then disposed within the interior portion of the outer shell of each base portion 102 by pouring the second material into the interior portion. Excess portions of the filler are removed by suitable processes, such as a modulated saw, abrasive wire, or hot wire, and the completed support base portion is then removed from the reusable mold.
While the disclosure has been described with respect to a limited number of embodiments, those skilled in the art, having benefit of this disclosure, will appreciate that other embodiments can be envisioned that do not depart from the scope of the disclosure as disclosed herein. Accordingly, the scope of the disclosure shall be limited only by the attached claims.
