US 7,124,767 B2 · Concrete washout container

Abstract

A washout container to which are mounted inclined ramps that allow a transit mixer, concrete pumping truck or other concrete handling vehicle to drive up over a portion of the container for dumping excess concrete and washing out waste concrete. The container cross-section may be rectangular to semi-circular, and is preferably fabricated with a steel structure. A watertight latching door assembly is coupled to the container to prevent leakage of collected liquid concrete waste material while allowing solidified concrete materials to be unloaded at a disposal site. The interior of the container is preferably lined with a material to which concrete will not adhere. The liner may be applied as a coating to the interior of the container or as a solid material retained within the container. In this way, solidified waste concrete can be easily removed from the container at the disposal site and preferably crushed for recycling.

Dependent claims

An apparatus for collecting a volume of hardening concrete washout material from a vehicle for disposal in a substantially hardened condition, comprising:

a portable, constructed concrete washout container comprising a constructed housing having a bottom, first and second opposite ends, first and second opposite sides extending between the ends, a substantially open and uncovered top, and a plurality of inner wall surfaces;
a door located at the first end and that is adjustable between opened and closed conditions;
a volume of concrete washout material located in a substantially hardening condition within the container;
a release material applied to at least one of said plurality of inner wall surfaces of said portable, constructed container;
wherein said release material comprises a material which is resistant to an adherence of the volume of concrete washout material when hardened into a substantially hardened condition within the portable, constructed container;
and
wherein the portable, constructed container further comprises a tapered width between the opposite sides relative to the ends such that a width of the container between the sides is greater toward the first end associated with the door than toward the second end.
