Description
CONTAINMENT WALL WITH REMOVABLE SECTION
This invention is in the field of containment structures for tanks and the like, and in particular a containment wall with improved access to the tank.
BACKGROUND
Containment structures are now commonly required to be placed around liquid storage tanks to prevent stored liquids from escaping the tank location if the tank leaks. 'T'hese containment structures generally include a wall around the tank, or around a plurality of tanks. The area enclosed and the height of the wall are designed to enable the structure to contain all the liquid that can be stored in the tanks enclosed. A membrane covers the ground under the tanks, and in some designs is sealed to the bottom edges of the walls.
In other designs the membrane follows the wall up and is fastened to the top of the wall so that no seal is required as the membrane is then continuous from the top of the wall s down and over the ground to the top of opposite walls.
A typical containment wall comprises vertical panels which are often corrugated to provide added rigidity, and the panels are connected together to form the wall. Braces

In other designs the membrane follows the wall up and is fastened to the top of the wall so that no seal is required as the membrane is then continuous from the top of the wall s down and over the ground to the top of opposite walls.
A typical containment wall comprises vertical panels which are often corrugated to provide added rigidity, and the panels are connected together to form the wall. Braces
2 are provide at intervals, conveniently where the panels are connected. The braces extend outward from the panels to the ground to support the walls in their vertical orientation.
Access is required to the tanks for removal of contents, cleaning, and like procedures.
Hoses must be connected to tank fittings to remove contents, and long wands are often inserted through the tank fittings to clean sand and the like from the tanks.
Tank fittings for cleaning and removal of contents are positioned generally near the bottom of the tanks, lower than the top of the containment wall. The containment wails are often quite close to the tanks, so that access over the wall to the tank fittings is not practical. Access ports are therefore provided in the middle of the walls with removable covers fastened and sealed to the wall. These access ports are quite small and so care must be taken when positioning the panels that the ports are aligned with the tank fittings.
In order to access the tanks for cleaning and content removal it is necessary to climb over the containment wall, often several times, to connect and disconnect equipment to the tank fittings, and for like purposes.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a containment wall apparatus that overcomes problems in the prior art.

SUMMARY OF THE INVENTION
It is an object of the present invention to provide a containment wall apparatus that overcomes problems in the prior art.
3 The present invention therefore provides a U-shaped containment wall panel that defines a wide opening between legs of the U. The bottom edge of the U-shaped panel rests on the ground, and the vertical ends of the panel are attached conventionally to adjoining containment wall panels, with braces attached as in the prior art to support the U-shaped panel in the vertical orientation. The bottom wall section of the U-shaped panel extends between the legs thereof and a top edge of the bottom wall section is located at distance above the ground that is selected to allow access as required for tank fittings that are located close to the inside of the containment wall.
A removable panel section covers the opening and seals to the vertical legs and the top edge of the bottom wall section of the U-shaped panel. Thus when the panel section is removed, an opening is formed in the containment wall that can extend a considerable lateral distance to provide a wide opening for easy access to tank fittings.
The opening significantly improves access for personnel into the area enclosed by the containment walls as well, since there is only a low portion of the U-shaped panel that a person working on the site must step over to enter the enclosure and gain access to the tanks for any required operations.

DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENTS
Fig.1 illustrates a top view of a containment structure 1 enclosing a tank 3.
An embodiment of a U-shaped containment wall panel 5 of the present invention, illustrated
5 in Figs. 2 and 3, is installed in one of the containment walls 7 forming the containment structure 1.
The U-shaped containment wall panel 5 defines a wide opening 9 between legs. I
l of the U. The bottom edge 13 of the U-shaped panel 5 rests on the ground 15, and the vertical ends of the panel are attached conventionally to adjoining containment wall panels 17, with braces 19 attached as in the prior art to support the U-shaped panel 5 in the vertical orientation. The bottom wall section 21 of the U-shaped panel 5 extends between the legs 11 thereof and a top edge 23 of the bottom wall section 21 is located at a distance above the ground 15 that is selected to allow access as required for tank fittings 25 on the tank 3 where the tank fittings 25 are located fairly close to the inside of the containment wall 7, as seen in Fig. 1.
A removable panel section 27 covers the opening 9 and seals to the vertical legs 11 and the top edge 23 of the bottom wall section 21 of the U-shaped panel 5. In Fig.
2 the removable panel section 27 is shown removed from the U-shaped panel 5, and Fig. 3 shows the panel section 27 installed in the U-shaped panel S. The removable panel section 27 is somewhat larger than the opening 9 so that when the removable panel
The U-shaped containment wall panel 5 defines a wide opening 9 between legs. I
l of the U. The bottom edge 13 of the U-shaped panel 5 rests on the ground 15, and the vertical ends of the panel are attached conventionally to adjoining containment wall panels 17, with braces 19 attached as in the prior art to support the U-shaped panel 5 in the vertical orientation. The bottom wall section 21 of the U-shaped panel 5 extends between the legs 11 thereof and a top edge 23 of the bottom wall section 21 is located at a distance above the ground 15 that is selected to allow access as required for tank fittings 25 on the tank 3 where the tank fittings 25 are located fairly close to the inside of the containment wall 7, as seen in Fig. 1.
A removable panel section 27 covers the opening 9 and seals to the vertical legs 11 and the top edge 23 of the bottom wall section 21 of the U-shaped panel 5. In Fig.
2 the removable panel section 27 is shown removed from the U-shaped panel 5, and Fig. 3 shows the panel section 27 installed in the U-shaped panel S. The removable panel section 27 is somewhat larger than the opening 9 so that when the removable panel
6 section 27 is placed in the opening 9 on the inside of the U-shaped panel 5, the edges of the removable panel section 27 extend past the opening 9 so same can bear against the inner surface 29 of the U-shaped panel 5 adjacent to the opening 9. A sealing member 31 is attached to either the edges of the removable panel section 27 or the inner surface of the U-shaped panel 5 adjacent to the opening 9.
The illustrated removable panel section 27 is shown with rotating latches 33 which pivot out to bear against the outer surface 35 of the U-shaped panel 5 adjacent to the opening 9 and are operative to draw the edges of the removable panel section 27 tightly against the seals 31 as shown in Fig. 4. Sliding latches or other mechanism known in the art could provide this required function as well.
Thus when the removable panel section 27 is removed, the opening 9 is formed in the containment wail 7 that can extend a considerable lateral distance to provide a wide opening 9 for easy access to tank fittings 25 for such operations as may be required. The opening 9 significantly improves access for personnel into the area enclosed by the containment walls 7 as well, since there is only the low bottom wall section 21 of the U-shaped panel 5 that a person working on the site must step over to enter the enclosure and gain access to the tank 3 for any required operations.
The U-shaped panel 5 can be placed in any of the containment walls 7 and connected to conventional wall panels 37 and braces 39 in the same manner as connecting any of the
The illustrated removable panel section 27 is shown with rotating latches 33 which pivot out to bear against the outer surface 35 of the U-shaped panel 5 adjacent to the opening 9 and are operative to draw the edges of the removable panel section 27 tightly against the seals 31 as shown in Fig. 4. Sliding latches or other mechanism known in the art could provide this required function as well.
Thus when the removable panel section 27 is removed, the opening 9 is formed in the containment wail 7 that can extend a considerable lateral distance to provide a wide opening 9 for easy access to tank fittings 25 for such operations as may be required. The opening 9 significantly improves access for personnel into the area enclosed by the containment walls 7 as well, since there is only the low bottom wall section 21 of the U-shaped panel 5 that a person working on the site must step over to enter the enclosure and gain access to the tank 3 for any required operations.
The U-shaped panel 5 can be placed in any of the containment walls 7 and connected to conventional wall panels 37 and braces 39 in the same manner as connecting any of the
7 conventional wall panels 37 to each other.
The removable panel section 27 shown in Fig. 4 includes bent ends which form flanges 41 that bear against the inner surface 29 of the U-shaped panel 5 adjacent to the opening.
This allows the inner and outer faces 43, 45 of the removable panel section 27 to be substantially aligned with the corresponding inner and outer surfaces 29, 35 of the U-shaped panel 5. Fig. 5 shows an alternate embodiment of the removable panel section 127 which is flat such that when positioned in the opening in the U-shaped panel 5 the removable panel section 127 is located inside the U-shaped panel 5.
Where the membrane sealing the ground to the containment walls 7 is of the type that is sealed to the bottom of the containment walls 7, sealing is required only of the removable panel section 27 to the U-shaped panel 5. Where the membrane is of the type that passes up the inside of the containment walls 7 and is held at the top of the containment walls 7, or folds over the top thereof, the membrane must be sealed to the inner surface 29 of the U-shaped panel 5 adjacent to the opening 9, and then the removable panel section 27 is sealed to the inner surface 29 of the U-shaped panel 5 adjacent to the opening 9 over the membrane.
Fig. 6 schematically illustrates a brace 51 attached to the removable panel section 27 by welding bolting or the like. The brace 51 extends outward from the panel section 27 to the ground to support the removable panel section 27, the U-shaped panel 5, and attached
The removable panel section 27 shown in Fig. 4 includes bent ends which form flanges 41 that bear against the inner surface 29 of the U-shaped panel 5 adjacent to the opening.
This allows the inner and outer faces 43, 45 of the removable panel section 27 to be substantially aligned with the corresponding inner and outer surfaces 29, 35 of the U-shaped panel 5. Fig. 5 shows an alternate embodiment of the removable panel section 127 which is flat such that when positioned in the opening in the U-shaped panel 5 the removable panel section 127 is located inside the U-shaped panel 5.
Where the membrane sealing the ground to the containment walls 7 is of the type that is sealed to the bottom of the containment walls 7, sealing is required only of the removable panel section 27 to the U-shaped panel 5. Where the membrane is of the type that passes up the inside of the containment walls 7 and is held at the top of the containment walls 7, or folds over the top thereof, the membrane must be sealed to the inner surface 29 of the U-shaped panel 5 adjacent to the opening 9, and then the removable panel section 27 is sealed to the inner surface 29 of the U-shaped panel 5 adjacent to the opening 9 over the membrane.
Fig. 6 schematically illustrates a brace 51 attached to the removable panel section 27 by welding bolting or the like. The brace 51 extends outward from the panel section 27 to the ground to support the removable panel section 27, the U-shaped panel 5, and attached
8 walls 7 in their vertical orientation if required by some particular design consideration.
Thus the present invention provides a containment wall panel that may be positioned at a desired location, or at a plurality of locations in the containment wall forming a containment structure enclosing a tank or a plurality of tanks to provide ready access to tank fittings as well as providing easy access to the enclosure inside the containment structure. The wide opening does not require precise placement to ensure adequate access to the required tank fittings.
The foregoing is considered as illustrative only of the principles of the invention.
Further, since numerous changes and modifications will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all such suitable changes or modifications in structure or operation which may be resorted to are intended to fall within the scope of the claimed invention.
