Abstract
A foldable conduit has a generally parabolic arched portion and a flat base. The arched portion comprises a pair of corrugated side walls which are connected with a hinge. The corrugations comprise alternating peak portions and valley portions. Each peak portion comprises a pair of generally vertical corrugation walls and a top wall connected with the corrugation walls. The top wall has a pair of ribs, each adjacent one of the pair of corrugation walls. Between the ribs is a recessed area. The ribs and recessed area are arcuate and generally undulating in cross section. The valley portion comprises an arcuate valley wall connected with the corrugation walls of adjacent peak portions. The flat base is a flexible sheet which may be perforated to permit fluid ingress and egress. The hinge and flexible base allow the side walls to be folded together with the base folded in between for more compact shipment.
