The present invention provides a deck for use with a~v~nicle for collecting and containing liquids therefrom, particularly when cleaning hazardous liquids from farm spray vehicles or loading the liquid on such vehicles.
BACKGROUND
Vehicles used to transport, cleanup, or spray hazardous liquids particularly vehicles used to carry farm spray equipment need to be cleaned of any residual hazardous liquids after use. Also the hazardous liquids need to be cleaned from or loaded on the vehicle in an environmentally safe manner without contaminating the ground or other supporting surface The vehicle used to transport, cleanup, or spray hazardous liquids is often a tractor, airplane, truck, or helicopter. When cleaning these types of vehicles the operator usually to moves the vehicle to a designated location and then rinses the vehicle clean with water. The water now containing the hazardous liquid is often allowed to run off the vehicle onto the ground or other supporting surface. This water may then make its way to a sewer system, waterways or ground water. This creates a problem in that hazardous liquids treated in this manner may over time become concentrated in the ground or other end location and cause environmental damage or pose a threat to people living or working in and around these areas.
One example of a deck for collecting and containing liquid when cleaning hazardous liquids is disclosed in U.S. Patent No. 5,300,341 of the present inventor and this includes a plurality of deck sections radiating outwardly from a central sump and supported on underlying support elements which are shaped cause the deck sections to slope toward the sump. This device has achieved some success but leaves opportunity for improvement in the construction of the device for ease and cost of manufacture.
It is one object of the present invention, therefore, to provide an improved deck which allows the collection and containment of hazardous or contaminated liquid from a vehicle in an environmentally safe manner without contaminating the ground or other supporting surface.

DETAILED DESCRIPTION
Referring to Figures 1, 2 and 3 a preferred embodiment of the deck is shown generally at 10. The deck 10 comprises, a plurality of interconnected impermeable deck sections 12, seal means 14, a containment means 16, a secondary containment means, a plurality of beam members 20, and clamping means 22.
In the example shown the plurality of interconnected impermeable deck sections 12 comprise sixteen triangular deck sections arranged in an octagon radiating outwards from the periphery of the containment means 16. In smaller embodiments, such as those having a diameter of the order of 18 feet, only eight sections can be used. Each one of the plurality of deck sections 12 slopes downwards and inwards to the centre of the octagon to the containment means 16 to drain liquid on the deck 10 into the containment means 16. Each deck section 12 has side edges 24 and 26. The side edge 24 of each respective deck section 12 abuts the side edge 26 of the deck section Iying adjacent to form a substantially continuous surface.
A berm or lip 27, see Figures 8 and 9, is arranged along the outer edge 29 of each deck section 12 extending upwards therefrom. The lip 27 helps prevent liquid from inadvertently escaping from the outer edge of the deck 10.
Each deck section 12 is comprised of a single piece of material.
The material used in this embodiment is a composite of plywood surrounded by a skin of fiberglass. The composite material makes the deck section 12 impervious to water and most other liquids. As an alternative to the plywood core, a polyurethane structural honeycomb foam can be used.
Referring to Figures 2, 3, 4 and 5 the deck 10 includes seal means 14 located between the abutting ed~qes 24 and 26 of each pair of adjacent deck sections 12 and running alon~q the full length of the deck sections 12 to prevent liquid leakage therebetween. The seal means 14 comprises two layers of protection. The first layer is a bead of flexible sealant 28 extending between each of the adjacent deck sections 12 adjacent top surfaces 30 thereof and running longitudinally therealong. The second layer is an elongate member of compressible sealing material 32 arranged between the adjacent deck sections 12 and below the flexible sealant 28. The member of compressible sealing material 32 extends along the length of the adjacent deck sections 12.
Referring to Figures 1, 10, and 11 the containment means 16 comprise a first container or sleeve 34 of double walled composite material having an open top 36, closed sides 38, and a closed bottom 40. The first container 34 is positioned in a cylindrical concrete pit 42 cast or located in a hole 42A in the ground or supporting surface 44. The concrete pit 42 thus forms a catchment container.
The first container 34 includes connection means in the form of an annular support flange 46 extending outwards from the top of the sides 38 of the container for fixing to the plate 99 and 100 of the clamping means 22 adjacent a lower end 78 of each of the plurality of deck sections 12.
A pump 50 is provided in the first container 34 for removal of the liquids which have been collected therein so that these can be transported and processed in a non-environmentally damaging manner at a location remote from the deck 10.
To provide additional protection against leakage or a spill the deck includes secondary containment means. The secondary containment means comprises a second container 52, liquid directing means 54, and a moisture detector 56.
The second container 52 is located in the hole 42 in the supporting surface 44 arranged around the sides 38 and bottom 40 of the first container 34 such that any leakage from the first container 34 with be contained by the second container 52. The second container 52, like the first container 34, is also made of a composite material.
Referring to Figures 2, 3, 4, 5 and 10 the liquid directing means 54 are arranged below the seal means 14 of the deck 10 for directing any liquid which may penetrate the seal means 14 to the second container 52.
The liquid directing means 54 comprise a plurality of flexible elongate strips, each one being arranged along the full length of a respective pair of abutting edges 24 and 26 of one of the pairs of adjacent deck sections 12. The liquid directing means 54 extend from the outer edge 58 of the deck to the second container 52 located at the centre of the deck 10. This ensures that any liquid penetrating the seal means 14 is communicated to the second container 52 thereby preventing it from contaminating the area under the deck 10.
Each flexible elongate strip 54 has a channel 60 arranged longitudinally along an upper face 62 thereof and has locating means in the form of a flange 64 projecting downwards and extending along each side 66 of the strip 54 to engage one of the plurality of beams 20 supporting the deck 10. In an alternative embodiment, see Figure 5, the liquid directing means may comprise a channel 61 in the top face 68 of the beam member 20. The channel 61 is arranged longitudinally along the beam 20.
Referring to Figure 10 a moisture detector 56 including an indicator is arranged within the second container 52 as part of the secondary containment means. If the moisture detector 56 detects any liquid in the second container 52 the indicator warns the operator that a leak has occurred in the deck 10 or the first containment means 16, so that appropriate measures can be undertaken.
Referring to Figures 1, 2, 3, 4, and 5 the plurality of beam members 20 support the deck sections 12 in the edge abutting relationship.
Each one of the plurality of beam members 20 has a top face 68 and a bottom face 70 arranged such that the top face 68 supports a lower surface 72 of the deck 10, and the bottom face 70 rests upon the supporting surface 44. Each beam 20 tapers from a first end 76 downwards to a second end 78. The first end 76 is arranged remote from the first container 34, and the second end 78 is arranged to lie adjacent the first container 34.
Referring to Figure 7 the beam members 20 support the flexible elongate strips 54 from below and are therefore also arranged along the full length of the abutting edges 24 and 26 of each pair of adjacent deck sections 12. Each beam 20 supports the abutting edges 24 and 26 of an adjacent pair of deck sections 12. The top face 68 of each one of the beam members 20 supports one of the flexible elongate strips 54 and is arranged such that the flanges 64 of the flexible elongate strips 54 engage respective side edges 80 and 82 of the respective beam member 20.
The first end 76 of each respective beam member 20 is of one of two types. The first type has a flat end 76a and is used to support the edges 24 and 26 of the deck sections 12 which abut to form a side of the octagon. The second type has an angled end 76b which corresponds to the angle of each corner of the octagon, and is used to support the edges 24 and 26 of the deck sections 12 which abut to form a corner of the octagon.
Referring to Figure 2 the beam members 20 are comprised of a pair of beams 84. Each beam 84 is T-shaped in cross section, and has arms 88 at a top end 68 and a stem 92 projecting perpendicularly therefrom. The T shaped beams 84 are arranged such that one T-shaped beam is inverted with respect to the other and the stems 92 of the T-shaped beams 84 are arranged to lie side by side to one another. The stems 92 of the T-shaped beams 84 are fixed to one another at points along the length of the beam member. While the arms 88 of the T-shaped beams 84 form the top 68 and bottom 70 faces of the beam member 20 respectively.
Referring to Figure 6 the stem 92 of each T-shaped beam 84 is cut at an angle along its length from a first end 76 to a second end 78. The angled stems 92 create the taper of the composite beam member 20 from the first end 76 downwards to the second end 78. The T-shaped beams 84 are comprised of a pultruded fiberylass composite material.
Other beam constructions may be utilized to support the deck 12 and are shown in figures 3, 4 and 5. Referring to Figure 3 each beam member 20 may comprise a solid beam 90 being frusto conical in cross section. The solid beams 90 may be comprised of a high density structural foam core 93 and a fiberglass composite skin 94 surrounding the core 93.
A second alternative beam shape, see Figure 4, may be a beam 5 95 which is rectangular in cross section comprising of a plurality of rectangular members 97 such as foam or wood fixed together longitudinally to form the beam. This arrangement is particularly attractive since it is inexpensive and can be supplied in long length and cut to length. In addition, the beams can be cut to provide the required angle of the deck 10 that is tapering in height or can be of constant height when the underlying footing can be sloped.
A third alternative, see Figure 5, may be a beam 101 which is M shaped in cross section and includes a lateral support member 103. The lateral support member 103 comprises an elongate tray member having upwardly extending flanges 105, each flange 105 being arranged to engage an outside face 107 of a bottom of each respective leg 109 of the beam 101 thereby preventing the bottom end of the legs 109 from tending to slide outwards when under load from the deck 10.
Referring to Figure 13 the deck 10 may also includes a plurality 20 of additional beam members 111 for supporting the deck sections 12. The additional beam members 111 are arranged such that they are positioned under and longitudinally along the deck sections 12 spaced from and between abutting edges of adjacent deck sections 12. The additional beam members 111 each have a top face 68 and a bottom face 70 and are 25 arranged such that the top face 68 supports the deck 10, and the bottom face 70 rests upon a supporting surface 44. The additional beam members 111 may be of any appropriate material and configuration.
-- 21 7~273 Referring to Figures 1, 8, and 9 arranged around an outer peripheral edge 29 of the deck 10 are end skirts 96 projecting downwards from the deck sections 12 thereby enclosing the outer peripheral edge 29 of the deck 10. At the first end 76 of each one of the plurality of beams 20 is a bracket 98 for joining the end skirts 96. The beams 20 of the type having a flat end 76a have a straight bracket 98a located at the first end thereof, and the beams 20 of the type having an angled end 76a have an angled bracket 98b at the first end thereof. The deck 10 is held in contact with the skirt 96 by a channel shaped bracket 115 arranged beneath the skirt 96 engaging the bottom and sides of the skirt 96 and a bolt 117 extending from each bracket 115 upwards through a hole 119 in the end of the deck 10 .
A liner 114 of plastics material about 30 mil in thickness is laid down under the full extent of the deck 10 and is arranged to lie under the beams 20, to prevents any liquid which may escape the deck surface 30, containment means 16, and the secondary containment means 18 from contaminating the ground or other supporting surface 44. The inner end of the liner 114 extends beneath the containment means 16 such that liquid will drain into the second container 54. The outer end portion of the liner 114 extends under the bracket 115 and skirt 96 then upwards over the outer surface 121 of the skirt 96 and finally inwards and over the top 123 of the skirt 96 between the skirt 96 and the bottom surface of the deck 10.
This secures the end of the liner 114 and prevents liquid from escaping from the outer end portion of the liner 114.
Referring to Figures 11 and 12 the clamping means 22 include retainer plates comprising a top plate 99 and a bottom plate 100 each having an aperture 102 spaced inwardly from a periphery thereof. The top and bottom retainer plates 99 and 100 are aligned vertically with respect to each other and are arranged to receive a lower end 78 of each one of the plurality of deck sections 12 therebetween. The plates 99 and 100 are fixed together by bolts 124 thereby holding the deck sections 12 in place.
S The bolts 124 extend through holes 127 in the plates 99 and 100 and through cooperating notches 126 in the deck sections 12. The clamping means 22 also include a seal member 106 arranged between one of the retainer plates, preferably the top plate 99, and the lower ends 78 of the deck sections 12 to prevent liquid leakage therebetween. A flange 108 extends from the top retainer plate 99 into the aperture 102 to provide a support for the support flange 46 of the first container 34. A seal 113 is arranged to lie between the annular flange 108 and the support flange 46 to prevent liquid leakage therebetween.
A cover grate 110 is located on top of the top plate 99 as a safety feature to allow the first container 34 to by driven over and to prevent anyone from accidentally fallin~ into the first container.
Referring to Figure 10 the hole 42 in the ground or supporting surface 44 which receives the first and second containers 34 and 52 is surrounded by a concrete pad 112 connected to the concrete sleeve 42 and extending outwardly therefrom about 4 inches thick which extends outwards to a distance of about three feet from the hole 42. The concrete pad 112 supports the inner hub of the deck 10 and the inner ends of the support beams. The composite liner 52 in the pit 42 is sealed to the liner 114 and rests in the pit. Thus any possible leak cannot escape through the liners to the soil or concrete on top of the soil and prevents any liquid which may escape the edges of the first and second containers 34 and 52 from contaminating the ground or other supporting surface 44.
Although in the preferred embodiment composite materials are extensively used any appropriate material may be used as an alternative.
The beams 20 used to support the deck 10 in the embodiment described above are sloped to provide an inward slope to the deck 10. One 5 example of an alternative means of providing a slope to the deck is to prepare the supporting surface at the site with the desired slope and to use beams 20 of constant height, thereby achieving the same result.
While one embodiment of the present invention has been described in the foregoing, it is to be understood that other embodiments 10 are possible within the scope of the invention. The invention is to be considered limited solely by the scope of the appended claims.

Each deck section 12 has side edges 24 and 26. The side edge 24 of each respective deck section 12 abuts the side edge 26 of the deck section Iying adjacent to form a substantially continuous surface.
A berm or lip 27, see Figures 8 and 9, is arranged along the outer edge 29 of each deck section 12 extending upwards therefrom. The lip 27 helps prevent liquid from inadvertently escaping from the outer edge of the deck 10.
Each deck section 12 is comprised of a single piece of material.
The material used in this embodiment is a composite of plywood surrounded by a skin of fiberglass. The composite material makes the deck section 12 impervious to water and most other liquids. As an alternative to the plywood core, a polyurethane structural honeycomb foam can be used.
Referring to Figures 2, 3, 4 and 5 the deck 10 includes seal means 14 located between the abutting ed~qes 24 and 26 of each pair of adjacent deck sections 12 and running alon~q the full length of the deck sections 12 to prevent liquid leakage therebetween. The seal means 14 comprises two layers of protection. The first layer is a bead of flexible sealant 28 extending between each of the adjacent deck sections 12 adjacent top surfaces 30 thereof and running longitudinally therealong. The second layer is an elongate member of compressible sealing material 32 arranged between the adjacent deck sections 12 and below the flexible sealant 28. The member of compressible sealing material 32 extends along the length of the adjacent deck sections 12.
Referring to Figures 1, 10, and 11 the containment means 16 comprise a first container or sleeve 34 of double walled composite material having an open top 36, closed sides 38, and a closed bottom 40. The first container 34 is positioned in a cylindrical concrete pit 42 cast or located in a hole 42A in the ground or supporting surface 44. The concrete pit 42 thus forms a catchment container.
The first container 34 includes connection means in the form of an annular support flange 46 extending outwards from the top of the sides 38 of the container for fixing to the plate 99 and 100 of the clamping means 22 adjacent a lower end 78 of each of the plurality of deck sections 12.
A pump 50 is provided in the first container 34 for removal of the liquids which have been collected therein so that these can be transported and processed in a non-environmentally damaging manner at a location remote from the deck 10.
To provide additional protection against leakage or a spill the deck includes secondary containment means. The secondary containment means comprises a second container 52, liquid directing means 54, and a moisture detector 56.
The second container 52 is located in the hole 42 in the supporting surface 44 arranged around the sides 38 and bottom 40 of the first container 34 such that any leakage from the first container 34 with be contained by the second container 52. The second container 52, like the first container 34, is also made of a composite material.
Referring to Figures 2, 3, 4, 5 and 10 the liquid directing means 54 are arranged below the seal means 14 of the deck 10 for directing any liquid which may penetrate the seal means 14 to the second container 52.
The liquid directing means 54 comprise a plurality of flexible elongate strips, each one being arranged along the full length of a respective pair of abutting edges 24 and 26 of one of the pairs of adjacent deck sections 12. The liquid directing means 54 extend from the outer edge 58 of the deck to the second container 52 located at the centre of the deck 10. This ensures that any liquid penetrating the seal means 14 is communicated to the second container 52 thereby preventing it from contaminating the area under the deck 10.
Each flexible elongate strip 54 has a channel 60 arranged longitudinally along an upper face 62 thereof and has locating means in the form of a flange 64 projecting downwards and extending along each side 66 of the strip 54 to engage one of the plurality of beams 20 supporting the deck 10. In an alternative embodiment, see Figure 5, the liquid directing means may comprise a channel 61 in the top face 68 of the beam member 20. The channel 61 is arranged longitudinally along the beam 20.
Referring to Figure 10 a moisture detector 56 including an indicator is arranged within the second container 52 as part of the secondary containment means. If the moisture detector 56 detects any liquid in the second container 52 the indicator warns the operator that a leak has occurred in the deck 10 or the first containment means 16, so that appropriate measures can be undertaken.
Referring to Figures 1, 2, 3, 4, and 5 the plurality of beam members 20 support the deck sections 12 in the edge abutting relationship.
Each one of the plurality of beam members 20 has a top face 68 and a bottom face 70 arranged such that the top face 68 supports a lower surface 72 of the deck 10, and the bottom face 70 rests upon the supporting surface 44. Each beam 20 tapers from a first end 76 downwards to a second end 78. The first end 76 is arranged remote from the first container 34, and the second end 78 is arranged to lie adjacent the first container 34.
Referring to Figure 7 the beam members 20 support the flexible elongate strips 54 from below and are therefore also arranged along the full length of the abutting edges 24 and 26 of each pair of adjacent deck sections 12. Each beam 20 supports the abutting edges 24 and 26 of an adjacent pair of deck sections 12. The top face 68 of each one of the beam members 20 supports one of the flexible elongate strips 54 and is arranged such that the flanges 64 of the flexible elongate strips 54 engage respective side edges 80 and 82 of the respective beam member 20.
The first end 76 of each respective beam member 20 is of one of two types. The first type has a flat end 76a and is used to support the edges 24 and 26 of the deck sections 12 which abut to form a side of the octagon. The second type has an angled end 76b which corresponds to the angle of each corner of the octagon, and is used to support the edges 24 and 26 of the deck sections 12 which abut to form a corner of the octagon.
Referring to Figure 2 the beam members 20 are comprised of a pair of beams 84. Each beam 84 is T-shaped in cross section, and has arms 88 at a top end 68 and a stem 92 projecting perpendicularly therefrom. The T shaped beams 84 are arranged such that one T-shaped beam is inverted with respect to the other and the stems 92 of the T-shaped beams 84 are arranged to lie side by side to one another. The stems 92 of the T-shaped beams 84 are fixed to one another at points along the length of the beam member. While the arms 88 of the T-shaped beams 84 form the top 68 and bottom 70 faces of the beam member 20 respectively.
Referring to Figure 6 the stem 92 of each T-shaped beam 84 is cut at an angle along its length from a first end 76 to a second end 78. The angled stems 92 create the taper of the composite beam member 20 from the first end 76 downwards to the second end 78. The T-shaped beams 84 are comprised of a pultruded fiberylass composite material.
Other beam constructions may be utilized to support the deck 12 and are shown in figures 3, 4 and 5. Referring to Figure 3 each beam member 20 may comprise a solid beam 90 being frusto conical in cross section. The solid beams 90 may be comprised of a high density structural foam core 93 and a fiberglass composite skin 94 surrounding the core 93.
A second alternative beam shape, see Figure 4, may be a beam 5 95 which is rectangular in cross section comprising of a plurality of rectangular members 97 such as foam or wood fixed together longitudinally to form the beam. This arrangement is particularly attractive since it is inexpensive and can be supplied in long length and cut to length. In addition, the beams can be cut to provide the required angle of the deck 10 that is tapering in height or can be of constant height when the underlying footing can be sloped.
A third alternative, see Figure 5, may be a beam 101 which is M shaped in cross section and includes a lateral support member 103. The lateral support member 103 comprises an elongate tray member having upwardly extending flanges 105, each flange 105 being arranged to engage an outside face 107 of a bottom of each respective leg 109 of the beam 101 thereby preventing the bottom end of the legs 109 from tending to slide outwards when under load from the deck 10.
Referring to Figure 13 the deck 10 may also includes a plurality 20 of additional beam members 111 for supporting the deck sections 12. The additional beam members 111 are arranged such that they are positioned under and longitudinally along the deck sections 12 spaced from and between abutting edges of adjacent deck sections 12. The additional beam members 111 each have a top face 68 and a bottom face 70 and are 25 arranged such that the top face 68 supports the deck 10, and the bottom face 70 rests upon a supporting surface 44. The additional beam members 111 may be of any appropriate material and configuration.
-- 21 7~273 Referring to Figures 1, 8, and 9 arranged around an outer peripheral edge 29 of the deck 10 are end skirts 96 projecting downwards from the deck sections 12 thereby enclosing the outer peripheral edge 29 of the deck 10. At the first end 76 of each one of the plurality of beams 20 is a bracket 98 for joining the end skirts 96. The beams 20 of the type having a flat end 76a have a straight bracket 98a located at the first end thereof, and the beams 20 of the type having an angled end 76a have an angled bracket 98b at the first end thereof. The deck 10 is held in contact with the skirt 96 by a channel shaped bracket 115 arranged beneath the skirt 96 engaging the bottom and sides of the skirt 96 and a bolt 117 extending from each bracket 115 upwards through a hole 119 in the end of the deck 10 .
A liner 114 of plastics material about 30 mil in thickness is laid down under the full extent of the deck 10 and is arranged to lie under the beams 20, to prevents any liquid which may escape the deck surface 30, containment means 16, and the secondary containment means 18 from contaminating the ground or other supporting surface 44. The inner end of the liner 114 extends beneath the containment means 16 such that liquid will drain into the second container 54. The outer end portion of the liner 114 extends under the bracket 115 and skirt 96 then upwards over the outer surface 121 of the skirt 96 and finally inwards and over the top 123 of the skirt 96 between the skirt 96 and the bottom surface of the deck 10.
This secures the end of the liner 114 and prevents liquid from escaping from the outer end portion of the liner 114.
Referring to Figures 11 and 12 the clamping means 22 include retainer plates comprising a top plate 99 and a bottom plate 100 each having an aperture 102 spaced inwardly from a periphery thereof. The top and bottom retainer plates 99 and 100 are aligned vertically with respect to each other and are arranged to receive a lower end 78 of each one of the plurality of deck sections 12 therebetween. The plates 99 and 100 are fixed together by bolts 124 thereby holding the deck sections 12 in place.
S The bolts 124 extend through holes 127 in the plates 99 and 100 and through cooperating notches 126 in the deck sections 12. The clamping means 22 also include a seal member 106 arranged between one of the retainer plates, preferably the top plate 99, and the lower ends 78 of the deck sections 12 to prevent liquid leakage therebetween. A flange 108 extends from the top retainer plate 99 into the aperture 102 to provide a support for the support flange 46 of the first container 34. A seal 113 is arranged to lie between the annular flange 108 and the support flange 46 to prevent liquid leakage therebetween.
A cover grate 110 is located on top of the top plate 99 as a safety feature to allow the first container 34 to by driven over and to prevent anyone from accidentally fallin~ into the first container.
Referring to Figure 10 the hole 42 in the ground or supporting surface 44 which receives the first and second containers 34 and 52 is surrounded by a concrete pad 112 connected to the concrete sleeve 42 and extending outwardly therefrom about 4 inches thick which extends outwards to a distance of about three feet from the hole 42. The concrete pad 112 supports the inner hub of the deck 10 and the inner ends of the support beams. The composite liner 52 in the pit 42 is sealed to the liner 114 and rests in the pit. Thus any possible leak cannot escape through the liners to the soil or concrete on top of the soil and prevents any liquid which may escape the edges of the first and second containers 34 and 52 from contaminating the ground or other supporting surface 44.
Although in the preferred embodiment composite materials are extensively used any appropriate material may be used as an alternative.
The beams 20 used to support the deck 10 in the embodiment described above are sloped to provide an inward slope to the deck 10. One 5 example of an alternative means of providing a slope to the deck is to prepare the supporting surface at the site with the desired slope and to use beams 20 of constant height, thereby achieving the same result.
While one embodiment of the present invention has been described in the foregoing, it is to be understood that other embodiments 10 are possible within the scope of the invention. The invention is to be considered limited solely by the scope of the appended claims.
