Detailed Description of Various Embodiments The description that follows and the embodiments described therein, are provided by way of illustration of an example, or examples, of particular embodiments of the principles of various aspects of the present invention.
These examples are provided for the purposes of explanation, and not of limitation, of those principles and of the invention in its various aspects. In the description, similar parts are marked throughout the specification and the drawings with the same respective reference numerals. The drawings are not necessarily to scale and in some instances proportions may have been exaggerated in order more clearly to depict certain features.
Referring to Figure 1, a containment ring 10 provides a portable wall system that can be erected and lined with a liner to support containment of accidentally released liquids or storage of liquids intentionally introduced within the ring.
Containment ring 10 is formed of a plurality of containment ring wall panels connected end to end. Panels 12 are connected by fasteners in an end to end manner to form a continuous ring. When installed on a ground surface S in this WSLegal\064621\00018\7194511v3 way, the ring, when lined with a liner forms a pond that can withstand expansive hoop stresses to contain liquids within the pond.
Each panel has edges 12a, 12b, ends 12c, 12d, an inwardly facing side 12i and an outwardly facing side 12o.
Containment ring 10 can be carried to a site as a plurality of individual panels and can be erected by connecting one panel to the next in series until a continuous ring is formed. While ring is shown as generally circular, other shapes are possible.
A single containment ring panel 112 is shown in Figures 2 and 3. A plurality of such panels can be connected end to end to form a ring similar to that shown in Figure 1. Each panel 112 is formed of a sheet material 113 and generally each panel is shaped in plan view as a four-sided polygon such as a square or a rectangle and includes a first long edge 112a, a second long edge 112b, a first end 112c and an opposite end 112d. While some embodiments may permit interchangeability of the panel orientations, generally the panel of the illustrated embodiment, has features that dictate the orientation of the panel. For example, first long edge 112a may have features thereon to accept attachment of the liner or features for handling that render it most suitable for positioning as the upper edge. As will be more fully described hereinbelow, ends 112c, 112d have fastening members thereon that further dictate the orientation of the panels in the ring.
While the panels may be flat and/or may be curved at site to form a ring, illustrated panel 112 is pre-formed to have a curvature from end 112c to end WSLega1\064621\00018\7194511v3 112d to have a curvature substantially corresponding to the curvature that panel is to have according to the diameter of the ring and the length of the panel.
The panels may be formed of various materials such as sheet materials of metal or polymers and may be formed to be smooth, or textured such as corrugated, etc. In the illustrated embodiment, panel 112 is formed of a smooth sheet metal, such as plate steel having a thickness of 1/8" to 1/4". The illustrated panel is reinforced by one or more reinforcements 114 formed in this embodiment as hollow beams, but could be a channel, I-beam, returns, corrugations, rod, etc.
Reinforcements 114 may extend diagonally, side-to-side and/or top-to-bottom on the panel. For example in the illustrated embodiment, the reinforcements include upright beams, cross members and thickened rims along first long edge 112a, which is the intended upper edge, and second long edge 112b. The reinforcements maintain structural rigidity of the walls and maintain the curvature of the panels. The thickened rim may be formed as a return of the sheet material of the panel or may be beams, as shown, attached to the sheet material.
Depending on the form of sheet material 113 used, fewer or more reinforcements may be necessary. The reinforcements may be positioned where they are most needed. For example, beams are shows extending closer to the bottom edge 112b where the panels, when in use, may have to withstand the greatest stresses.
The panels connect in an end to end arrangement and ends 112b, 112c are formed to accept fasteners that secure the panels together. The fasteners may take various forms such as pins, clips, bolts, clamps, etc. In the illustrated embodiment, the fasteners are installed through apertures in the end of the panels to secure the panels together. For example, ends 112b, 112c each have apertures 118 through which fasteners may be installed. Each end 112b, 112c has the same pattern of apertures such that the apertures substantially align VVSLegal\064621\00018\7194511v3 panel to panel when adjacent panels are brought together. For example, apertures 118 are positioned similarly along the ends of each panel, for example substantially equidistantly from the top of each panel, such that the apertures substantially align panel to panel when adjacent panels are brought together.
Generally, there is a plurality of apertures along each end such that adjacent panels are secured together at more than one location. Apertures 118 may be positioned to address the loads to be placed thereon. For example, there may be a closer spacing, and therefore more, apertures 118 adjacent lower edge 112b than upper edge 112a, as the assembled ring in use may have to withstand greater radially outwardly directed forces at its lower edge than at its upper edge.
The panels also each include an end to end alignment system to facilitate arrangement and assembly of the panels to form the ring. In particular, panel 112 includes one or more protrusions 120 extending out from one of its ends that are intended to be inserted into openings 122 on an end of a next panel in series in the ring. Because panel 112 is intended to be connected at both ends 112c and 112d to adjacent panels, each panel 112 has protrusions 120 at one end 112d and openings 122 at opposite end 112c. While in the illustrated embodiment, each panel has four protrusions alignable with four openings on an adjacent panel, it is to be understood that there can be any number of protrusions/openings on the end, with two to four being thought to be the most effective to balance operation with simplicity.
As with apertures 120, the protrusions may be positioned on the end to address stresses and operability during panel installation. For example, as shown in Figure 2b, protrusions 120 may have a closer spacing adjacent the bottom end 112b than adjacent upper edge 112a. Since the panels can be supported on the ground during assembly, an installer may more readily align pins that are closer to the ground, than those that are higher up the sides of the panels.
Figure 5a is a perspective view of a first part of a fastener useful in the present invention; and Figure 5b is a perspective view of a second part of a fastener useful in the present invention.

Containment ring 10 can be carried to a site as a plurality of individual panels and can be erected by connecting one panel to the next in series until a continuous ring is formed. While ring is shown as generally circular, other shapes are possible.
A single containment ring panel 112 is shown in Figures 2 and 3. A plurality of such panels can be connected end to end to form a ring similar to that shown in Figure 1. Each panel 112 is formed of a sheet material 113 and generally each panel is shaped in plan view as a four-sided polygon such as a square or a rectangle and includes a first long edge 112a, a second long edge 112b, a first end 112c and an opposite end 112d.

For example, first long edge 112a may have features thereon to accept attachment of the liner or features for handling that render it most suitable for positioning as the upper edge. As will be more fully described hereinbelow, ends 112c, 112d have fastening members thereon that further dictate the orientation of the panels in the ring.
While the panels may be flat and/or may be curved at site to form a ring, illustrated panel 112 is pre-formed to have a curvature from end 112c to end WSLega1\064621\00018\7194511v3 112d to have a curvature substantially corresponding to the curvature that panel is to have according to the diameter of the ring and the length of the panel.
The panels may be formed of various materials such as sheet materials of metal or polymers and may be formed to be smooth, or textured such as corrugated, etc. In the illustrated embodiment, panel 112 is formed of a smooth sheet metal, such as plate steel having a thickness of 1/8" to 1/4". The illustrated panel is reinforced by one or more reinforcements 114 formed in this embodiment as hollow beams, but could be a channel, I-beam, returns, corrugations, rod, etc.
Reinforcements 114 may extend diagonally, side-to-side and/or top-to-bottom on the panel. For example in the illustrated embodiment, the reinforcements include upright beams, cross members and thickened rims along first long edge 112a, which is the intended upper edge, and second long edge 112b. The reinforcements maintain structural rigidity of the walls and maintain the curvature of the panels. The thickened rim may be formed as a return of the sheet material of the panel or may be beams, as shown, attached to the sheet material.
Depending on the form of sheet material 113 used, fewer or more reinforcements may be necessary. The reinforcements may be positioned where they are most needed. For example, beams are shows extending closer to the bottom edge 112b where the panels, when in use, may have to withstand the greatest stresses.
The panels connect in an end to end arrangement and ends 112b, 112c are formed to accept fasteners that secure the panels together. The fasteners may take various forms such as pins, clips, bolts, clamps, etc. In the illustrated embodiment, the fasteners are installed through apertures in the end of the panels to secure the panels together. For example, ends 112b, 112c each have apertures 118 through which fasteners may be installed. Each end 112b, 112c has the same pattern of apertures such that the apertures substantially align VVSLegal\064621\00018\7194511v3 panel to panel when adjacent panels are brought together. For example, apertures 118 are positioned similarly along the ends of each panel, for example substantially equidistantly from the top of each panel, such that the apertures substantially align panel to panel when adjacent panels are brought together.
Generally, there is a plurality of apertures along each end such that adjacent panels are secured together at more than one location. Apertures 118 may be positioned to address the loads to be placed thereon. For example, there may be a closer spacing, and therefore more, apertures 118 adjacent lower edge 112b than upper edge 112a, as the assembled ring in use may have to withstand greater radially outwardly directed forces at its lower edge than at its upper edge.
The panels also each include an end to end alignment system to facilitate arrangement and assembly of the panels to form the ring. In particular, panel 112 includes one or more protrusions 120 extending out from one of its ends that are intended to be inserted into openings 122 on an end of a next panel in series in the ring. Because panel 112 is intended to be connected at both ends 112c and 112d to adjacent panels, each panel 112 has protrusions 120 at one end 112d and openings 122 at opposite end 112c. While in the illustrated embodiment, each panel has four protrusions alignable with four openings on an adjacent panel, it is to be understood that there can be any number of protrusions/openings on the end, with two to four being thought to be the most effective to balance operation with simplicity.
As with apertures 120, the protrusions may be positioned on the end to address stresses and operability during panel installation. For example, as shown in Figure 2b, protrusions 120 may have a closer spacing adjacent the bottom end 112b than adjacent upper edge 112a. Since the panels can be supported on the ground during assembly, an installer may more readily align pins that are closer to the ground, than those that are higher up the sides of the panels.
VVSLega1\064621\00018\7194511v3 Protrusions 120 and openings 122 facilitate alignment of the ends of the panels.
Protrusions 120 and openings 122 are formed to cooperate to bring the ends of adjacent panels together with their apertures 118 aligned and ready for accepting the fasteners. The corresponding fit of the opening over its protrusion and the position of the protrusions and the openings on their panel ends are selected to facilitate alignment. For example, each opening 122 is shaped to fit over and generally correspond to the sectional base shape (i.e. footprint shape) of the protrusion over which it is intended to be installed. For example, each protrusion 120 has a base 120a with a diameter and the opening for that protrusion has a diameter only slightly larger than the base diameter, to fit over the protrusion but restrict lateral and vertical movement of the opening about the protrusion.
Protrusions 120 and openings 122 are positioned on the ends relative to apertures 118 to ensure that when the protrusion on one panel is inserted into its mating opening on an adjacent panel, the apertures 118 on both the panels substantially align. For example, the protrusions and the openings on respective panel ends are each spaced substantially equidistantly from the apertures on those panel ends. Stated another way, the protrusion is spaced a first distance from the aperture on its panel and the opening is spaced from the aperture on its panel a distance that is substantially equal to the first distance, such that when protrusion is inserted into the opening the two apertures become aligned with each other. While aperture alignment is the primary goal, it is noted that each mating protrusion 120 and opening 122 may be equidistant from the upper edge and/or the lower edge so that the mating of the protrusions and the openings also cause the alignment of the panels along their upper and/or lower edges.
Protrusions 120 and openings 122 are formed to cooperate to bring the ends of adjacent panels together with their apertures 118 aligned and ready for accepting the fasteners.

VVSLega1\064621\00018\7194511v3 Protrusions 120 may be formed to facilitate their insertion into their openings.
For example, the protrusions may be faceted or circular in cross section, with a circular cross section appearing to mitigate catching between the parts.
Alternately or in addition, protrusions 120 may each have a tapered outboard tip 120b. For example, each protrusion 120 may have a tapering diameter from its base end 120a to its outboard tip 120b, such that they are formed as pyramids or cones. As such, protrusions present a smaller sized outboard tip 120b that can more readily be inserted through its opening 122, which has a diameter slightly larger than the diameter at base end 120a.
In the illustrated embodiment, protrusions 120 protrude beyond the end of the panel. For example, in this embodiment, protrusions 120 are mounted on their panel with an axis x defined by their length extending substantially parallel with a long axis of the panel and in plane with the thickness of the panel.
Protrusions 120 can be mounted to the panel in various ways, for example, as by welding, fasteners, forming integral as an extension of the material of the panel, etc.
In this embodiment, protrusions 120 are inserted through openings in the panel sheet material and welded into position.
Openings 122 can be formed in various ways. In this embodiment, openings 122 each span a plane substantially orthogonal to a plane defined by the end 112c to end 112d length of the panel. For example, the material forming the edges of the opening, which defines the plane spanned by the opening, extends substantially orthogonal to the main expanse of the panel.
Openings 122, while they are shown as fully open front and back, may have a back wall. For example, they may be formed by punching, pressing, drilling, WSLega1\064621\00018\7194511v3 cutting holes out of the panel material or may be formed by indenting, pressing, milling, removing to form an indentation into the end of the panel.
In this embodiment, panel 112 has a flange 124c, 124d formed on each end 112c, 112d and protrusions 120 extend out from one flange and openings 122 are formed in the other flange. In this embodiment, each flange extends out from the outer facing side substantially radially outwardly relative to the panel curvature. While the flanges appear to be extending substantially orthogonally from the plane defined by the panel end, the panel is curved and therefore the flange may actually extend at as angle less than orthogonal especially if the end to end curvature of the panel is significant, as will be appreciated.
Apertures 118, 118 are also formed in each flange 124c, 124d.
Figures 4 show the assembly of two panels 212', 212" in the process to form a containment ring. Panels 212' has an opening 222 formed on its end and panel 212" has a protrusion 220 formed on its end, opening 222 and protrusion 220 are formed to cooperate and fit together. Panels 212', 212" each have apertures 218', 218", respectively, formed on their ends through which a fastener can be inserted to hold the panels together. The opening and the protrusion are each positioned substantially equidistantly from the upper edges of their panels, with the distance d" between protrusion 220 and upper edge 212a" being approximately equal to the distance d' between opening 222 and upper edge 212a'. Likewise, the apertures 218', 218" are each positioned substantially equidistantly from the upper edges of their panels, with the distance dd"
between aperture 218" and upper edge 212a" being approximately equal to the distance dd' between aperture 218' and upper edge 212a'. Thus, when the protrusion 220 is aligned with the opening 222, apertures 218', 218" are also aligned.
For example, the protrusions may be faceted or circular in cross section, with a circular cross section appearing to mitigate catching between the parts.
Alternately or in addition, protrusions 120 may each have a tapered outboard tip 120b. For example, each protrusion 120 may have a tapering diameter from its base end 120a to its outboard tip 120b, such that they are formed as pyramids or cones. As such, protrusions present a smaller sized outboard tip 120b that can more readily be inserted through its opening 122, which has a diameter slightly larger than the diameter at base end 120a.
In the illustrated embodiment, protrusions 120 protrude beyond the end of the panel. For example, in this embodiment, protrusions 120 are mounted on their panel with an axis x defined by their length extending substantially parallel with a long axis of the panel and in plane with the thickness of the panel.
Protrusions 120 can be mounted to the panel in various ways, for example, as by welding, fasteners, forming integral as an extension of the material of the panel, etc.
In this embodiment, protrusions 120 are inserted through openings in the panel sheet material and welded into position.
Openings 122 can be formed in various ways. In this embodiment, openings 122 each span a plane substantially orthogonal to a plane defined by the end 112c to end 112d length of the panel. For example, the material forming the edges of the opening, which defines the plane spanned by the opening, extends substantially orthogonal to the main expanse of the panel.
Openings 122, while they are shown as fully open front and back, may have a back wall. For example, they may be formed by punching, pressing, drilling, WSLega1\064621\00018\7194511v3 cutting holes out of the panel material or may be formed by indenting, pressing, milling, removing to form an indentation into the end of the panel.
In this embodiment, panel 112 has a flange 124c, 124d formed on each end 112c, 112d and protrusions 120 extend out from one flange and openings 122 are formed in the other flange. In this embodiment, each flange extends out from the outer facing side substantially radially outwardly relative to the panel curvature. While the flanges appear to be extending substantially orthogonally from the plane defined by the panel end, the panel is curved and therefore the flange may actually extend at as angle less than orthogonal especially if the end to end curvature of the panel is significant, as will be appreciated.
Apertures 118, 118 are also formed in each flange 124c, 124d.
Figures 4 show the assembly of two panels 212', 212" in the process to form a containment ring. Panels 212' has an opening 222 formed on its end and panel 212" has a protrusion 220 formed on its end, opening 222 and protrusion 220 are formed to cooperate and fit together. Panels 212', 212" each have apertures 218', 218", respectively, formed on their ends through which a fastener can be inserted to hold the panels together. The opening and the protrusion are each positioned substantially equidistantly from the upper edges of their panels, with the distance d" between protrusion 220 and upper edge 212a" being approximately equal to the distance d' between opening 222 and upper edge 212a'. Likewise, the apertures 218', 218" are each positioned substantially equidistantly from the upper edges of their panels, with the distance dd"
between aperture 218" and upper edge 212a" being approximately equal to the distance dd' between aperture 218' and upper edge 212a'. Thus, when the protrusion 220 is aligned with the opening 222, apertures 218', 218" are also aligned.
5'SLegA\064621\00018\7194511v3 As shown in Figure 4a, to form the ring, panels 212, 212" are positioned to be brought together end to end along a direction in plane with the overall end to end planes of the panels. Panels 212', 212" may be carried to a selected site and supported on their base edges. In one embodiment, lifting eyes 228 are provided for securing shackles therein for lifting with a crane, etc.
In any event, panels 212', 212" are positioned with the outer facing surface 224c' of one panel's end flange facing the outer facing surface 224d" of the other panel's end flange and with the two ends generally orientationally aligned, such as both substantially vertical, substantially aligned side to side and substantially aligned along their upper edges 212a', 212a". As the two flanges are brought together, arrows A, protrusions 220 protrude, substantially orthogonally from flange surface 224d" and are the first structure to come into contact with the flange of the other panel. Protrusions 220 can then be generally pushed into their respective openings 222. After the protrusions 220 protrude to some degree each through of their respective openings 222, the panels can be pushed together end to end (Figure 4b).
To facilitate the movement of panels together, end to end, connection points such as eyes 229 can be connected to the panels adjacent their ends to which pulling device can be attached to pull the two panels together. For example, pulling chains, a boomer, also known as a come-along style ratchet, etc. can be connected between eyes 229 and operated to pull the panel edges together.
The tapering form of protrusions 220 avoids the need to precisely align the protrusions with their openings. For example, as the protrusions are pushed toward and through the openings, the edges of openings 222 abut against the WSLega1\064621\00018\7194511v3 protrusions and guide the flanges into alignment until each opening 222 encircles the base end 220a of its protrusion and the flange outer facing surfaces 224c' and 224d" are very close, if not touching. In this position, apertures 218', 218"
are aligned between the two flanges 224c, 224d and protrusions 220 and openings 222 temporarily hold the flanges together.
Because the apertures are aligned by use of protrusions 220 and openings 222, fasteners 219 can be readily inserted into the apertures 118 to secure the flanges, and therefore the panels, together (Figure 4c).
As noted above, fasteners 219 can take various forms. For example, suitable elongate fasteners for securing through apertures 218', 218" include bolts, pins, wire, straps, etc. In the illustrated embodiment of Figures 4 and 5, for example, fasteners 219 include a pin 230 and a locking structure, in this embodiment a lock wedge 232. Pin 230 is an elongate member, having a shaft 230a sized to pass through the apertures, and in particular aligned apertures 218', 218", with an exposed length to be engaged by the locking structure. Pin 230 includes a head 230b which is enlarged in at least one diametrical dimension relative to the diameter of the shaft and cannot pass through the apertures. Thus, head 230b butts against the flange and prevents pin 230 from passing fully through the apertures. Pin 230 can also have a tapered leading end 230c to facilitate insertion into an aperture. While the pin is shown according to one embodiment, it is to be appreciated that it can be varied in numerous ways, including being U-shaped, L-shaped, threaded, blunt ended, etc.
Lock wedge 232 engages shaft 230a and prevents the pin from falling out of the apertures. While other locking structures may be employed to hold the pin in the apertures, lock wedge 232 is easy to use and durable. Lock wedge 232 for VVSLega1\064621\00018\7194511v3 example, has a slot 232a sized to engage in a necked region 230a' along the shaft of the pin.
The lock wedge generally has a tapered end 232b and a thicker end 232c and is generally U-shaped including a pair of arms 232d extending from the thicker end 232a toward tapered end 232b. The space between arms 230d defines the slot 232a. Slot 232a opens from tapered end 232b of the lock wedge and arms 232d have a relatively narrower outboard ends at tapered end 232b and gradually thicken toward their bases. Thus, the arms form the wedge-shaped form and have ramped surfaces 232d' on at least a common side, which in this embodiment is the front side.
Necked region 230a' of the pin has a diameter less than that of shaft 230 and shoulders 230a" are defined between necked region 230a' and the larger diameter of the shaft away from the necked region. Slot 232a is sized to fit over necked region 230a' but cannot fit over other regions of the shaft. Thus, once the wedge is placed with slot 232a slid over necked region 230a', lock wedge 232 cannot slide along shaft 230a.
In use, pin 230 is inserted through the apertures of aligned flanges 224a, 224b until head 230b butts against the flange material. This exposes shaft 230 and necked region 230a' on a side of the flanges opposite the head. Lock wedge 232 is then installed over the necked region of the pin. To do so, lock wedge 232 is positioned with slot 232a over the necked region of the pin and lock wedge 232 is pushed down until the necked region is located up in the length of the slot.
Since pin 230 is held against any substantial movement away from the lock wedge, arms 232d can be driven down on either side of necked region 230a'.
Eventually, ramped surfaces 232d' of the arms engage against shoulders 230a"
In any event, panels 212', 212" are positioned with the outer facing surface 224c' of one panel's end flange facing the outer facing surface 224d" of the other panel's end flange and with the two ends generally orientationally aligned, such as both substantially vertical, substantially aligned side to side and substantially aligned along their upper edges 212a', 212a". As the two flanges are brought together, arrows A, protrusions 220 protrude, substantially orthogonally from flange surface 224d" and are the first structure to come into contact with the flange of the other panel. Protrusions 220 can then be generally pushed into their respective openings 222. After the protrusions 220 protrude to some degree each through of their respective openings 222, the panels can be pushed together end to end (Figure 4b).
To facilitate the movement of panels together, end to end, connection points such as eyes 229 can be connected to the panels adjacent their ends to which pulling device can be attached to pull the two panels together. For example, pulling chains, a boomer, also known as a come-along style ratchet, etc. can be connected between eyes 229 and operated to pull the panel edges together.
The tapering form of protrusions 220 avoids the need to precisely align the protrusions with their openings. For example, as the protrusions are pushed toward and through the openings, the edges of openings 222 abut against the WSLega1\064621\00018\7194511v3 protrusions and guide the flanges into alignment until each opening 222 encircles the base end 220a of its protrusion and the flange outer facing surfaces 224c' and 224d" are very close, if not touching. In this position, apertures 218', 218"
are aligned between the two flanges 224c, 224d and protrusions 220 and openings 222 temporarily hold the flanges together.
Because the apertures are aligned by use of protrusions 220 and openings 222, fasteners 219 can be readily inserted into the apertures 118 to secure the flanges, and therefore the panels, together (Figure 4c).
As noted above, fasteners 219 can take various forms. For example, suitable elongate fasteners for securing through apertures 218', 218" include bolts, pins, wire, straps, etc. In the illustrated embodiment of Figures 4 and 5, for example, fasteners 219 include a pin 230 and a locking structure, in this embodiment a lock wedge 232. Pin 230 is an elongate member, having a shaft 230a sized to pass through the apertures, and in particular aligned apertures 218', 218", with an exposed length to be engaged by the locking structure. Pin 230 includes a head 230b which is enlarged in at least one diametrical dimension relative to the diameter of the shaft and cannot pass through the apertures. Thus, head 230b butts against the flange and prevents pin 230 from passing fully through the apertures. Pin 230 can also have a tapered leading end 230c to facilitate insertion into an aperture. While the pin is shown according to one embodiment, it is to be appreciated that it can be varied in numerous ways, including being U-shaped, L-shaped, threaded, blunt ended, etc.
Lock wedge 232 engages shaft 230a and prevents the pin from falling out of the apertures. While other locking structures may be employed to hold the pin in the apertures, lock wedge 232 is easy to use and durable. Lock wedge 232 for VVSLega1\064621\00018\7194511v3 example, has a slot 232a sized to engage in a necked region 230a' along the shaft of the pin.
The lock wedge generally has a tapered end 232b and a thicker end 232c and is generally U-shaped including a pair of arms 232d extending from the thicker end 232a toward tapered end 232b. The space between arms 230d defines the slot 232a. Slot 232a opens from tapered end 232b of the lock wedge and arms 232d have a relatively narrower outboard ends at tapered end 232b and gradually thicken toward their bases. Thus, the arms form the wedge-shaped form and have ramped surfaces 232d' on at least a common side, which in this embodiment is the front side.
Necked region 230a' of the pin has a diameter less than that of shaft 230 and shoulders 230a" are defined between necked region 230a' and the larger diameter of the shaft away from the necked region. Slot 232a is sized to fit over necked region 230a' but cannot fit over other regions of the shaft. Thus, once the wedge is placed with slot 232a slid over necked region 230a', lock wedge 232 cannot slide along shaft 230a.
In use, pin 230 is inserted through the apertures of aligned flanges 224a, 224b until head 230b butts against the flange material. This exposes shaft 230 and necked region 230a' on a side of the flanges opposite the head. Lock wedge 232 is then installed over the necked region of the pin. To do so, lock wedge 232 is positioned with slot 232a over the necked region of the pin and lock wedge 232 is pushed down until the necked region is located up in the length of the slot.
Since pin 230 is held against any substantial movement away from the lock wedge, arms 232d can be driven down on either side of necked region 230a'.
Eventually, ramped surfaces 232d' of the arms engage against shoulders 230a"
VVSLegaR064621\00018\7194511v3 and since the wedge thickness increases, continued advancement of the wedge over the pin, wedges the lock wedge between shoulders 230a" and flange 224c and pulls head 230b tight against flange 224d. Wedge 232 can be hammered into a tight position between shoulder 230a" and flange 224. Pin 230 and wedge 232, therefore, secure flanges 224c, 224d tightly together. While necked region 230a' may not extend fully from shoulder 230a" to head 230b, the necked region should extend sufficiently close to the head to ensure that the thickness of flanges 224c, 224d can be pinched between wedge 232 and head 230b.
After driving the lock wedge into place, it will remain in position by frictional engagement such that even if the wedge is installed in or migrates to a position where thicker end 232c is below tapered end 232b, the wedge will remain in place.
Necked region 230a and slot 232a each are relatively open such that they are not easily obstructed by debris. They are each easy to use, quickly installed and durable. Shoulder 230a" can be angled relative to long axis x' of the pin to facilitate advancement of the wedge over the pin, to more evenly distribute the expansive forces on the pin and to urge forces exerted on the wedge to be translated primarily along the long axis x' of the pin.
One or more clamps can be employed, if necessary, as a back up to hold flanges 224c, 224d together before fasteners 219 are installed. However, after the fasteners are installed, any clamps, or pulling devices on eyes 229, cables in eyes 228 may be removed.

WSLegM\064621\00018\7194511v3 After panel 212 is attached to panel 212", further panels may be installed and connected to opposite ends of both of these panels in a similar manner to form the complete ring. Thereafter, a liner of liquid containing material can be installed therein. The liner can be laid out within the ring and urged up the inner sides of the ring before being connected to the upper edge. This forms a containment ring pond that is ready to contain liquid.
