The ability to effectively fill pits or rock fissures, or secure poles or soil, etc. can be important for building a variety of structures. Historically, concrete has been used to fill pits or rock fissures, or secure poles or soil. Concrete is heavy and cumbersome to use, especially for smaller projects.
Accordingly, there is a continuing need for methods and systems that can fill and secure structures in a safe and efficient manner
In accordance with various embodiments, a method generally features agitating a first liquid component and a second liquid component in a container until the first liquid component and the second liquid component are a mixture of uniform color, without an appearance of marbling and swirling, when viewed through a transparent portion of the container. The mixture of uniform color may be poured from the container into a receiving structure. The mixture of uniform color may be transformed into a closed-cell polyurethane structure within the receiving structure.
In accordance with various embodiments, a method generally features a container that may include a transparent portion that reveals an interior portion of the container, an access aperture communicating with the interior portion of the container, and a lid adjacent the access aperture. A first liquid component may be placed through the access aperture into the interior portion of the container. A second liquid component may be poured through the access aperture into the interior portion of the container. The lid of the container may be closed to fully enclose the first and second liquid components. The first and second liquid components in the container may be agitated until the first and second liquid components are a mixture of uniform color, without an appearance of marbling and swirling, when viewed through the transparent portion of the container. The lid of the container may be opened to expose the mixture of uniform color. The mixture of uniform color may be poured from the container into a receiving structure. The mixture of uniform color may be transformed into a closed-cell polyurethane structure within the receiving structure.
These and various other features and advantages that characterize the claimed invention will be apparent upon reading the following detailed description and upon review of the associated drawings.
Reference will now be made in detail to one or more examples of the disclosure depicted in the figures. Each example is provided by way of explanation of the disclosure, and not meant as a limitation of the present disclosure. For example, features illustrated or described as part of one embodiment may be used with another embodiment to yield still a different embodiment. Other modifications and variations to the described embodiments are also contemplated within the scope and spirit of the present disclosure.
The first container 100 may contain a first liquid component 114, and a headspace 116 in the interior portion 104 above the first liquid component 114, wherein the first component is a first liquid component 114. The headspace 116 provides volume in the interior portion 104 of the first container 100 for the first liquid component 114 to be agitated inside the container 100 when the lid 108 is closed.
A second liquid component 134 may be placed through the aperture 126 into the interior portion 124 of the second container 120. Wherein the second component 134 is a liquid second liquid component 134.
The first liquid component 114 and the second liquid component 134 may combine to transform the first and second liquid components 114, 134 into a polyurethane, such as a closed-cell polyurethane. Wherein the transformation of the combined, and mixed, first and second liquid components 114 and 134 into the closed-cell polyurethane, results in a volumetric expansion of the mixture, and the transformation of the liquid mixture into a ridged structure.
In an exemplary embodiment of the present disclosure, the first liquid component 114 may belong to the chemical family of polyol system, such as a polyol available from E. I. du Pont de Nemours and Company, commonly referred to as DuPont (Global Headquarters: DuPont Building, 1007 Market Street, Wilmington, Del. 19898).
In an exemplary embodiment of the present disclosure, the second liquid component 134 may belong to the chemical family of the Aromatic Isocyanate with chemical name Diphenylmethane Diisocyanate (MDI). The Aromatic Isocyanate or MDI is available from a variety of sources, such as Dow Chemical Company, commonly referred to as Dow (Corporate Headquarters: The Dow Chemical Company, 2030 Dow Center, Midland, Mich. 48674).
In various embodiments, the first liquid component has a first density and the second liquid component has a second density, and the first density is less than the second density. In addition, the first liquid component has a first viscosity and the second liquid component has a second viscosity, and the first viscosity is greater than the second viscosity.
As seen in
In other words, the first container may support all the weight of the second container, which holds the second liquid component, such that the aperture of the second container and the access aperture of the first container cooperate to form a conduit between the second container and the first container to pour substantially all of the second liquid component into the first container.
The first and second liquid components may be agitated by manually shaking the container. In other words, the user does not use a machine to agitate the first and second liquid components. For instance, the user could hold the handle 110 of the first container 100 in the hand of the user. In addition, the first and second liquid components may be agitated by mechanically shaking the container via a shaker machine, such as a paint shaker machine. The first and second liquid components could be agitated by mechanically stirring the first and second liquid components via a stirrer, with the lid 108 open or closed.
The first and second liquid components, i.e., the mixture 154, in the first container 100 can be agitated until the first and second liquid components are of uniform color, without the appearance of marbling and swirling, when viewed through the transparent portion 102 of the first container 100. The transparent portion 102 enables the user to clearly see if and when the first and second liquid components are of uniform color, without the appearance of marbling and swirling.
The mixture of uniform color can transform into a closed-cell polyurethane structure 170 within the receiving structure 160. Upon the completion of the transformation of the mixture 154, into its closed-cell polyurethane structural form, the space 165 between the receiving structure 160, and the target structure 164, is filed, and the closed-cell polyurethane structure 170 is in continuous, pressing contact adjacency with both the interior wall of the receiving structure 160 and the exterior surface of the target structure 164.
The receiving structure 160 can take various forms and sizes. In
For combinations of the receiving structure 160 and the target structure 164 of these sizes, a range of the total volume of the first and second liquid components can be in a range from about 14 fluid ounces to about 50 fluid ounces. The lower end of the range, e.g., about 14 fluid ounces, may be result in the closed-cell polyurethane structure 170 that is too soft for practical use in supporting the target structure 164 in the receiving structure 160. However, it is contemplated that continued improvements in closed-cell polyurethane structure materials may lead to smaller total fluid volumes yielding the closed-cell polyurethane structure 170 that can support the target structure 164.
The higher end of the end, e.g., about 50 fluid ounces, should result in the closed-cell polyurethane structure 170 that is very strong and effective in supporting the target structure 164, but the high volume of the first and second liquid components may not be viable from an economic standpoint. That is the high end of the total volume of about 50 fluid ounces may cost too much to handle, ship, use, etc. in the marketplace. However, it is contemplated that closed-cell polyurethane structure materials may become cheaper in the future, such that cost is not a limiting factor in choosing the total volume of the first and second liquid components. In addition, about 50 fluid ounces or more may be too heavy for the user to agitate the first and second liquid components.
When the target structure 164 is the 1 and ⅝ inch post, the inner diameter 172 is 6″ and a depth 174 of 18″. In this situation, the total volume of the first and second liquid components may be about 16 fluid ounces. The total volume of the first and second liquid components can be about 16 fluid ounces, with the volume of the first liquid component about 8 fluid ounces and the volume of the second liquid component about 8 fluid ounces. As above, other volumes of the first and second liquid components are possible, and the first and second liquid components may not be of the same volume as each other. For combinations of the receiving structure 160 and the target structure 164 of these sizes, a range of the total volume of the first and second liquid components can be in a range from about 8 fluid ounces to about 28 fluid ounces.
Other volumes of the first and second liquid components are possible. The first and second liquid components may not be of the same volume as each other. In other words, the volume of the first liquid component and the volume of the second liquid component may be volumes other than a one to one (1:1) ratio between the first and second liquid components.
All dimensions provided in the disclosure are approximate, and it is understood that by conventional dimensions may be exemplary, such as the 4″ by 4″ wooden post may actually be 3.5″ by 3.5″.
In a preferred embodiment, the target structure 164, is centered within the receiving structure 160. To sustain this relationship, a stabilization structure 176 may be provided. The target structure 164 may be positioned in the receiving structure 160 in a desired position, i.e. centered. The target structure 164 is stabilized in the receiving structure 160 via cooperation of the stabilization structure 176 with the target structure 164. The stabilization structure 176 engages the target structure 164 and the ground surface 162. There may be a plurality of stabilization structures 176. However, the stabilization structure 176 is optional. For example, the target structure 164 in the receiving structure 160 may be stabilized by the hand of the user in a selected orientation of the target structure 164 in relation to the receiving structure 160.
The target structure 164 may be stabilized in the receiving structure 160 by the user holding the target structure 164 in the desired position.
When the mixture of uniform color has transformed into the closed-cell polyurethane structure 170, the closed-cell polyurethane structure 170 will act to stabilize the target structure 164 in the desired position without ongoing stabilization of the target structure 164 in the receiving structure 160 by the stabilization structure 176, the user, or other suitable manner of stabilization.
At process step 204, a container is provided. The container may include a transparent portion that reveals an interior portion of the container, an access aperture communicating with the interior portion of the container, and a lid adjacent the access aperture.
At process step 206, a first liquid component is placed through the access aperture into the interior portion of the container.
At process step 208, a second liquid component is poured through the access aperture into the interior portion of the container.
At process step 210, the lid of the container is closed to fully enclose the first and second liquid components.
At process step 212, the first and second liquid components in the container are agitated until the first and second liquid components are a mixture of uniform color, without an appearance of marbling and swirling, when viewed through the transparent portion of the container.
At process step 214, the lid of the container is opened to expose the mixture of uniform color.
At process step 216, the mixture of uniform color is poured from the container into a receiving structure.
At process step 218, the mixture of uniform color is transformed into a closed-cell polyurethane structure within the receiving structure.
At process step 220, the routine 200 ends.
It should be noted that the various steps are not limited to singular function. That is, several of the steps, such as steps 206 and 208 can be carried out simultaneously. Likewise, the position of the elements of the closed-cell polyurethane transformation can vary without deterring from the spirit of the present disclosure. Regardless, various steps of the operation 200 of
