1. A slurry truck transport bin, comprising:
a double-walled bin tub of molded resin, the tub having:
an inner wall bounding a cavity for containing unsolidified waste slurry, the bin tub having a lip bounding an opening of the cavity;an outer wall defining channels extending across a bottom of the bin tub opposite the cavity opening, the channels sized to accept forklift tines; andstructural ribs connecting the inner and outer walls and arranged to support a floor of the cavity under weight of over a metric ton of unsolidified waste as the bin tub is lifted by forklift; and a double-walled lid of molded resin configured to span the cavity opening, the lid defining an underside perimeter channel sized to receive the lip of the bin tub, wherein the inner wall of the bin tub at the lip, and an inner wall surface of the lid bounding the perimeter channel, are of complementary tapers, and wherein the relative sizes of the bin tub lip and the inner wall surface of the lid are such that when the lid is placed on the bin tub with the lip in the channel, the inner wall of the bin tub is positioned to engage the tapered inner wall surface of the lid with the lip of the bin lid spaced from a bottom of the lid channel, and wherein the bin tub is of such flexibility that cinching the lid to the bin tub with a force sufficient to cause the tapered inner wall surface to slide along an inner tub surface until the bin tub lip contacts the bottom of the lid channel, flexes the bin tub lip outward without cracking, thereby forming a barrier to slurry flow along two sets of contacting surfaces between the bin tub and the lid. |
