Electro-Osmotic Pulse Technology for Control of Water Seepage in Various Civil Works Structures
Abstract
Electro-osmotic pulse (EOP) was evaluated in the laboratory to compare the electrokinetic forces developed by the EOP system to the hydraulic forces within 4-in.-thick concrete. Systems were installed in two Civil Works structures, the old lock house at Lock and Dam 7 at Dresbach, MN, and in a section of gallery at Lock 27 at Granite City, IL. Laboratory testing indicates that EOP is able to dry the walls of concrete Civil Works structures up to 30 ft of head through a 4-in.-thick slab of concrete, and that EOP can be used to dry the concrete in lock house basements and lock galleries. The plate cathodes mounted in the water on the lock walls are effective cathode placements. Probe cathodes are also effective embedded in the lock walls. The effectiveness of probe cathodes is based on the surface area and not the manufacturing techniques used.
