TITLE OF THE INVENTION:
Modular Wall Section For A Liquid Containment Barrier and A Liquid Containment Barrier FIELD OF THE INVENTION
The present invention relates to a modular wall section for a liquid containment barrier and a liquid containment barrier constructed from a plurality of modular wall sections.
BACKGROUND OF THE INVENTION
When a liquid storage tank ruptures, gallons of liquid escape from the ruptured tank onto surrounding lands. If the liquid in the liquid storage tank were chemicals or petroleum products, the rupture of such a liquid storage tank would cause significant environmental damage. In order to prevent this from occurring laws have been passed requiring that a liquid containment barrier be built to surround each liquid storage tank. These liquid containment barriers are presently being built from a plurality of modular wall sections fabricated from metal plate or concrete.
STJNMRY OF THE INVENTION
What is required is an inexpensive and yet effective modular wall section for a liquid containment barrier.
According to the present invention there is provided a modular wall section for a liquid containment barrier which includes a shell form body having sidewalls connected by an upper bridge section. Each of the sidewalls converge inwardly from a bottom edge toward the bridge section. The bottom edge of at least one of the sidewalls has an outwardly projecting anchoring flange with openings adapted to receive ground anchors.
The modular wall section, as described above, is relatively inexpensive to produce and transport. It is preferred that the shell from body be formed from a single sheet of material. Suitable materials include sheet metal, aluminum and fire resistant polymer plastic. The preferred material at present is sheet metal, as sheet metal is a relatively low cost material and the required shape can be stamped out in a relatively inexpensive manufacturing process. The shell form bodies can then be formed into a rectangular enclosure and secured together inexpensively by overlapping the shell form bodies with sealant positioned between the overlap and the overlap secured together by sheet metal screws.
Although beneficial results may be obtained through the use of the modular wall section, as described above, even more beneficial results may be obtained when the shell form body has internal braces positioned transversely between the sidewalls.

FIGURE 4 is a perspective view of the modular wall section illustrated in FIGURE 1, showing detail as to k i G' IGI ;11 i attachment of a liquid containment liner.
DETAILED DESCRIPTION OF THE PREFERRED ErBODIMENT
The preferred embodiment, a modular wall section for a liquid containment barrier generally identified by reference numeral 10, will now be described with reference to FIGURES 1 through 4.
Structure and Relationship of Parts:
Referring to FIGURE 1, there is provided a modular wall section 10 for a liquid containment barrier which includes a shell form body 12 formed from a single sheet of sheet metal 14. Shell form body 12 has a first sidewall 16 and a second sidewall 18. First side wall 16 has a first bottom edge 20 and second sidewall 18 has a second bottom edge 22. First sidewall 16 and second sidewall 18 are connected by an upper bridge section 24. First sidewall 16 and second sidewall 18 converge inwardly from first bottom edge 20 and second bottom edge 22 toward bridge section 24. Referring to FIGURE 3, shell form body 12 has internal braces 26 positioned transversely between first sidewall 16 and second sidewall 18. Referring to FIGURE 1, first bottom edge 20 of first sidewall 16 has an outwardly projecting anchoring first flange 28 with openings 30 to receive ground anchors 32 illustrated in FIGURE 3. Referring to FIGURE 1, second bottom edge 22 of second sidewall 18 has an outwardly projecting second flange 34 which is adapted to attach to a liquid containment liner 36 illustrated in FIGURE 4. Referring to FIGURE 3, outwardly projecting second flange 34 has openings 3o 38 which are adapted to receive screws 40 which are used to secure polymer plastic containment liner 36 between a elongate flat clamping bar 42 and second flange 34.
Operation:
The use and operation of modular wall section 10 to form a liquid containment barrier, generally indicated by reference numeral 100, will now be described with reference -_ CA 02390137 2006-06-19 to FIGURES 1 through 3. Referring to FIGURE 2, there is provided a liquid containment barrier 100 which includes a plurality of shell form bodies 12. Shell form bodies 12 are formed into a rectangular enclosure 112 and secured together to surround a liquid storage tank 114.
Referring to FIGURE 3, shell form bodies 12 are overlapped with sealant 116 positioned between overlap 118.
Overlap 118 is secured together by sheet metal screws 120. A
polymer plastic containment liner 36 is secured to second anchoring flange 34. In the event that liquid storage tank 114 ruptures and liquids escape from ruptured tank 114, liquid containment barrier 100 will contain escaping liquid and prevent liquid from causing significant environmental damage to the surrounding environment. Sealant 116 which is positioned between overlap 118 prevents leaks between shell form bodies 12 while polymer plastic containment liner 36 that is secured to second anchoring flange 34 prevents leaks underneath shell form bodies 12. Polymer plastic containment liner 36 is secured to outwardly projecting second flange 34 by placing sealant 116 on outwardly projection second flange, and then lying polymer plastic liner 36 over outwardly projecting second flange 34. Elongate flat clamping bar 42 is then laid over polymer plastic liner, and screws 40 are inserted through flat clamping bar and outwardly projecting second flange 34 so as to clamp polymer plastic liner between elongate flat clamping bar 42 and outwardly projecting second flange 34 to secure it in place. Screws 40 do not extend through liner or sealant, and do not extend past outwardly extending second flange 34.
The modular wall sections 10 provide a number of advantages. The modular wall sections 10 are inexpensive to manufacture, as compared to sections for other liquid containment barriers. With braces 26 removed, large numbers of the modular wall sections 10 can be stacked for transport to job sites. Even with braces 26 in place, modular wall ~ II I ; ~I i sections 10 can still be stacked, but not to the same extent.
Once installed to form liquid containment barrier 100, modular wall sections 10 are as stable as, and in some cases more stable than, other liquid containment barriers of this 5 type.
It will be recognized by one skilled in the art that there are a variety of materials out of which modular wall sections 100 may be made in addition to sheet metal, aluminum lo and polymer plastic. It will also be recognized that there are other methods of securing the liquid containment liner to the modular wall sections, other than clamping with a clamping bar. Care should be taken to select a liquid containment liner that is compatible with the liquid to be contained. Care should also be taken to select a sealant that is compatible with the containment liner. When joining the modular wall sections at each corner, care must be taken in selecting the angles and cutting the modular wall sections to make the connection.
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.
