Waterjet Contractor Helps Audubon Bridge Construction Site

摘要

Midwest Mobile Water jet developed unique waterjet cutter that was dropped 20-40 feet inside the piles to cut them off three feet below the riverbed. When record spring floods made it impossible for the Audubon Bridge's contractors to remove their construction pier piles using conventional methods, they turned to Midwest Mobile Waterjet, a Minnesota-based waterjet contractor whose motto is "if it is possible, we can do it." The bridge contractors had just finished constructing the longest cable-stayed bridge in the Western Hemisphere, the John James Audubon Bridge, north of Baton Rouge, LA, and they faced hefty penalties if they did not meet their deadline for removing the temporary piles from the Mississippi River. Normally most of the steel piles would have been on dry land and easily dug up, cut with a torch and removed with a crane, but the flood waters left them deep in the water, inaccessible with standard equipment.
