SCRAPERS VS. HAULERS ON LONG, SLIPPERY ROUTES

Two new locks are under construction "in-the-dry" on the West Virginia side of the Ohio River. The new 1200- and 600-ft-long, 110-ft-wide locks will replace 600- and 360-ft-long locks of the same width. They will relieve traffic jams on the river currently caused by having to break apart barge "trains," which can be as long as 1000 ft, to pass through the locks. The new locks are being built east of the existing locks and river. The earthmoving job involves excavating 14 1/2 million cu yd of earth and hauling it to various locations throughout the site. The top soil is 1 ft thick. Below that is from 15 to 45 ft of impervious clay and silt and a silty-clayey mixture atop 45 to 75 ft of granular soil. Below that is a 5-ft-thick layer of weathered sandstone. Soils down to the weathered rock are being excavated. The sandstone will be pressure-grouted and will form the base for the lock's monolith base. Computer analysis is helping to optimize the use of scrapers, excavators, dozers and trucks. Further details are provided in this article.
