SUMMARY OF THE INVENTION
What is required is an alternative form of modular panel for a liquid containment barrier.
According to the present invention there is provided a modular panel for a liquid containment barrier which includes a planar metal body having a top edge, a bottom edge, a first end, a second end, a first side and a second side. A
stabilizing flange projects outwardly from the first side along the bottom edge. At least two supporting legs are angled outwardly and downwardly from the second side. A coupling is provided at each of the first end and the second end. The coupling at the second end is adapted to connect with the coupling at the first end whereby the body can be connected with adjacent bodies end to end to form an enclosure.
According to another aspect of the present invention there is provided a liquid containment barrier consisting of a plurality of modular panels, as described above, joined end to end to form a rectangular enclosure.
The modular panel, as described above, can rapidly be deployed as a free standing liquid containment barrier.
Support legs are used instead of posts. This eliminates the time consuming and labour intensive effort of driving posts into the ground. The system is ideal for environmentally sensitive areas as there is minimal ground disturbance.
Although beneficial results may be obtained through the use of the modular panel, as described above, with the supporting legs projecting outwardly from the body, the modular panels are bulky to transport. Even more beneficial results may, therefore, be obtained when at least two leg attachment brackets are positioned along the second side and the at least two supporting legs are detachably secured to the at least two leg attachment brackets. There are different engagements which are viable. Beneficial results have been obtained through the use of a tongue and groove engagement. Each of the at least two leg attachment brackets define laterally spaced grooves.
Each of the at least two supporting legs have opposed sides with outwardly extending longitudinal tongues that are adapted to engage the laterally spaced grooves on the at least two leg attachment brackets. This form of engagement is preferred as it enables the leg to move up and down. This is important as in some places the ground level will fall due to settling and in other areas the ground level with rise due to frost heaves.
The leg moves up and down to adjust to changing ground conditions, so the leg is always in contact with the ground.
Without this ability to adjust, some supporting legs would be suspended in the air as a result of a fall in the ground level and other legs would be transmitting forces exerted by heaving ground directly to the panel.

There are different types of couplings which can be used to connect the modular panels. Beneficial results have been obtained through the use of a pin style of coupling. The coupling at the first end includes several first engagement members, each of which has a first pin receiving aperture. The coupling at the second end includes several second engagement members, each of which has a second pin receiving aperture.
The first engagement members are connected to the second engagement members by aligning the first pin receiving aperture of one of the first engagement members with the second pin receiving aperture of one of the second engagement members and inserting a pin.
Although beneficial results may be obtained through the use of the modular panel, as described above, even more beneficial results may be obtained when the support legs firmly engage the ground to avoid any sliding movement. Even more beneficial results may, therefore, be obtained when each supporting leg has a ground engaging end with downwardly extending gripping teeth.
Although beneficial results may be obtained through the use of the modular panel, as described above, such systems are intended for use with liners and it is preferred that provision should be made for retaining the liners in position. Even more beneficial results may, therefore, be obtained when the body has a liner retaining cap that engages the top edge.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The preferred embodiment, a modular panel for a liquid containment barrier generally identified by reference numeral 10, will now be described with reference to FIGURES 1 through 5.
Structure and Relationship of Parts:
Referring to FIGURE 1 there is provided a modular panel 10 which includes a planar metal body 12 that has a top edge 14, a bottom edge 16, a first end 18, a second end 20, a first side 22 and a second side 24. Referring to FIGURE 2, a stabilizing flange 26 projects outwardly from first side 22 along bottom edge 16. Referring to FIGURE 1, leg attachment brackets 28 are positioned along second side 24. Referring to FIGURE 4, leg attachment brackets 28 have laterally spaced grooves 30. Referring to FIGURE 1 supporting legs 32 are detachably secured to leg attachment brackets 28. Referring to FIGURE 4, supporting legs 32 have opposed sides 34 with outwardly extending longitudinal tongues 36 that are adapted to engage laterally spaced grooves 30 on leg attachment brackets 28. Supporting legs 32 are capable of moving up and down with longitudinal tongues 36 travelling along grooves 30.
Referring to FIGURE 1, supporting legs 32 are angled outwardly and downwardly from second side 24. Each supporting leg 32 has a ground engaging end 38 with downwardly extending gripping teeth 40.
A coupling 42 is provided at each of first end 18 and second end 20 of body 12. Referring to FIGURES 3 and 5, coupling 42 at second end 20 is adapted to connect with coupling 42 at first end 18 whereby body 12 can be connected 5 with adjacent bodies 12 end to end to form an enclosure generally referenced by numeral 44. Referring to FIGURE l, in the illustrated embodiment, coupling 42 at first end 18 includes several first engagement members 46 each of which has a first pin receiving aperture 48. Coupling 42 at second end 20 includes several second engagement members 50, each of which has a second pin receiving aperture 52. First engagement members 46 are connected to second engagement members 50 by aligning first pin receiving aperture 48 of one of first engagement members 46 with second pin receiving aperture 52 of one of second engagement members 50 and inserting a pin 54.
Body 12 has a liner retaining cap 56 that engages top edge 14.
Operation:
The use and operation of modular panel for a liquid containment barrier generally identified by reference numeral 10, will now be described with reference to FIGURES 1 through 5. Referring to FIGURE l, a plurality of panels 10 can be transported to a site where enclosure 44 is desired to be assembled. Supporting legs 32 are then detachably secured to leg attachment brackets 28 on second side 24 of each body 12 by engaging outwardly extending longitudinal tongues 36 on opposed sides 34 of supporting legs 32 with laterally spaced grooves 39 on leg attachment brackets 28. Referring to FIGURE
2, when secured to body 12 of panel 10, supporting legs 32 will angle outwardly and downwardly from second side 24.
Referring to FIGURE 5, after supporting legs 32 have been detachably secured to each body 12, bodies 12 are assembled in end to end relation to form rectangular shaped enclosure 44, with first side 22 of each body 12 facing inward and second side 24 of each body 12 facing outward from enclosure 44.
Referring to FIGURES 1 and 3, in order to secure bodies 12 in end to end relation, second end 20 of each of body 12 is aligned with first end 18 of adjacent body 12 so that first engagement members 46 are connected to second engagement members 50 by aligning first pin receiving aperture 48 of one of first engagement members 46 with second pin receiving aperture 52 of one of second engagement members 50 and inserting pin 54 as described above.
Referring to FIGURES 2 and 5, once panels 10 have been secured to form rectangular enclosure 44, a liner 58 may be positioned on first side 22 of body 12 and secured to liner retaining cap 56 that engages top edge 14 of body 12. Referring to FIGURE 5, rectangular enclosure 44 serves as a precautionary measure in the event an enclosed tank 60 should rupture. If tank 60 ruptures, enclosure 44 will contain any liquids which escape from tank 60 within enclosure 44, thereby limiting environmental damage. Referring to FIGURE 2, as rising liquid within enclosure 44 increases pressure on panels 10, gripping teeth 40 on ground engaging end 38 of support legs 32 dig into an underlying ground surface 62 to prevent any movement of panels 10 thereby maintaining the integrity of enclosure 44.
As the ground underlying enclosure 44 rises due to frost heaves and falls due to settling, support legs 32 adjust to the changing ground by sliding up and down. This adjustment takes place without human intervention, with longitudinal tongues 36 travelling along grooves 30. This ensures that ground engaging end 38 of support legs 32 is always in contact with the ground.
In this patent document, the word "comprising" is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article "a" does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be one and only one of the elements.
It will be apparent to one skilled in the art that modifications may be made to the illustrated embodiment without departing from the spirit and scope of the invention as hereinafter defined in the Claims.
The first engagement members are connected to the second engagement members by aligning the first pin receiving aperture of one of the first engagement members with the second pin receiving aperture of one of the second engagement members and inserting a pin.
Although beneficial results may be obtained through the use of the modular panel, as described above, even more beneficial results may be obtained when the support legs firmly engage the ground to avoid any sliding movement. Even more beneficial results may, therefore, be obtained when each supporting leg has a ground engaging end with downwardly extending gripping teeth.
Although beneficial results may be obtained through the use of the modular panel, as described above, such systems are intended for use with liners and it is preferred that provision should be made for retaining the liners in position. Even more beneficial results may, therefore, be obtained when the body has a liner retaining cap that engages the top edge.

Body 12 has a liner retaining cap 56 that engages top edge 14.
Operation:
The use and operation of modular panel for a liquid containment barrier generally identified by reference numeral 10, will now be described with reference to FIGURES 1 through 5. Referring to FIGURE l, a plurality of panels 10 can be transported to a site where enclosure 44 is desired to be assembled. Supporting legs 32 are then detachably secured to leg attachment brackets 28 on second side 24 of each body 12 by engaging outwardly extending longitudinal tongues 36 on opposed sides 34 of supporting legs 32 with laterally spaced grooves 39 on leg attachment brackets 28. Referring to FIGURE
2, when secured to body 12 of panel 10, supporting legs 32 will angle outwardly and downwardly from second side 24.
Referring to FIGURE 5, after supporting legs 32 have been detachably secured to each body 12, bodies 12 are assembled in end to end relation to form rectangular shaped enclosure 44, with first side 22 of each body 12 facing inward and second side 24 of each body 12 facing outward from enclosure 44.
Referring to FIGURES 1 and 3, in order to secure bodies 12 in end to end relation, second end 20 of each of body 12 is aligned with first end 18 of adjacent body 12 so that first engagement members 46 are connected to second engagement members 50 by aligning first pin receiving aperture 48 of one of first engagement members 46 with second pin receiving aperture 52 of one of second engagement members 50 and inserting pin 54 as described above.

As the ground underlying enclosure 44 rises due to frost heaves and falls due to settling, support legs 32 adjust to the changing ground by sliding up and down. This adjustment takes place without human intervention, with longitudinal tongues 36 travelling along grooves 30. This ensures that ground engaging end 38 of support legs 32 is always in contact with the ground.
