Book Description
Tests were made to evaluate a proposed technique for removing ice from lock walls during winter navigation. The technique involves use of a high-pressure water jet to slice through ice collars that adhere to vertical walls. The test equipment consisted of: (1) A jet lance tipped with a nozzle designed to produce a long coherent jet; (2) A small tractor (hydraulically driven) to carry the lance; and (3) A high-pressure pump unit to supply water to the lance. Tests were made with operating pressures from 3,000 to 14,000 lbf/sq in. and nozzle diameters from 0.063 to 0.152 in. Most of the work involved pressures around 9,000 lbf/sq in. and nozzle diameters of approximately 0.09 in. Traverse speeds were in the range 3 to 17 ft/min. Jet penetrations of up to 4 ft. were achieved in a single pass, and the equipment proved capable of cleaning the lock wall under the prevailing conditions. However, performance was somewhat less favorable than had been predicted, and a revised scheme involving changes in lock operating procedures was proposed. (Author).

Book Description
Four methods for removing the ice buildup on navigation lock walls on the Poe Locks at Sault Ste. Marie, Michigan, were investigated: mechanical pneumatic boots, high-pressure water jets, mechanical chain saws, and chemical coatings. Two of the more promising means of ice removal, the chain saw and the chemical coatings, are being developed further so that they may be used as operational aids for lock wall deicing during the winter navigation season.
