Eric’sons was able to improve on the original trench drain design of this VDOT project. Multiple jack and bore pipe connections under I-264 were eliminated by the DuraTrench product. With its long +300ft continuous sloped runs the drains were able to tie into existing box culverts. Eric’sons manufactured custom flumes from the trench, at a steep angle, which attached to the crown of the existing concrete box culverts. The overall DuraTrench design improved the flow of solids out of the drain, reducing maintenance. A special inlet, attached to the trench drain, was even designed, to allow drainage during paving. As I-264 is an active roadway this was a critical safety factor. Trench drain grates were secured with four point lock downs (non-removable available) to withstand the dynamic loading of traffic.
