Abstract
A wash fluid containment system includes an elevated, fluid impervious surface upon which items to be washed are placed for washing. The surface is configured to cause wash fluid to flow to an edge of the surface and off of the surface to prevent buildup of wash fluid on the surface. A collecting trough is positioned in fluid flow communication with the edges of the surface to which the fluid flows to catch and collect the fluid as it flows from the surface. Used wash fluid is taken from the collecting trough for disposal or recycling and solids and debris can be easily removed from the trough.
Claims17
A low profile pad upon which vehicles having weight, including heavy vehicles, and other items are positioned and supported to remove debris from any desired external location thereof:
- the pad comprising an impervious undulating top comprising ridges and sloped grooves;
- the ridges structurally supporting the weight of a vehicle and other items to be cleaned and the sloped grooves accommodating immediate flow of cleaning liquid and debris removed from the vehicle along the slope in the grooves to prevent accumulation of debris on the pad;
- at least one trough at an edge of the pad into which the cleaning liquid and debris collectively flow and are temporarily stored, and from which stored cleaning liquid and debris are selectively removed, at one or more sites offset from without interference with any cleaning taking place on the pad.
A vehicle receiving pad comprising:
- an impervious top comprising:
- (a) spaced generally transversely directed impervious ridge portions upon which vehicles, including heavy vehicles, and other items are supported in load-transferring relation for exterior cleaning using a cleaning liquid;
- and (b) impervious generally transversely directed sloped drainage corridors disposed below the ridge portions into which used cleaning liquid and removed debris collectively flow, each drainage corridor being sloped toward at least one side of the pad;
- a trough into which the cleaning liquid and debris, discharged from the covering, collectively flow and are temporarily stored, so as to prevent any material debris accumulation in the drainage corridors and from which the liquid and debris can later be generally segregated and separately removed.
A washing apparatus for vehicles and other items encumbered by exterior debris comprising:
- an impervious low profile pad having a gentle slope to at least one edge thereof, the pad comprising vehicle support areas and slightly lower liquid flow path-defining channels, by which essentially all debris washed from the vehicle or other item using wash liquid is carried off the pad with the wash liquid to the at least one edge;
- at least one drainage storage trough disposed directly adjacent to and below the at least one edge of the pad into which essentially all of the debris and all of the used wash liquid run from the flow path-defining channels and are accumulated, stored and subsequent selective segregated and removed.
A wash liquid dual usage flat impervious pad comprising:
- vehicle generally flat support structure exposed at a top of the impervious pad, for supporting a vehicle encumbered with external debris, as the debris is washed therefrom using a liquid;
- gently sloped drainage structure below the support structure and exposed at the top of the impervious pad into which substantially all of the removed debris and used washing liquid collectively flow to at least one trough for temporary storage, the trough being disposed offset from the pad adjacent to an edge of the pad thereby avoiding accumulation of any substantial amount of debris on the pad and interference with washing on the pad.
