Case Study: Constructing Grout Curtain for Dam

Published Year: 1960

  • The Columbia River Valley at the dam site is a wide canyon dividing the Columbia Plateau on the east from the Entiat Mountains on the west.

Case Study: Sealing Leaks in Coal Mine Slope

Published Year: 1960

  • During the winter months, small drips from the roof froze into large ice masses, obstructing the passage of men and equipment, and becoming a safety hazard.

Case Study: Consolidating Weakly Cemented Sandstone During Cross-Cut Construction

Published Year: 1960

  • Problem: At Seafield Colliery, three cross-cuts, 16-17 feet wide by 12- feet high, were being driven horizontally through the Millstone Grit series, which contained many weakly cemented and porous sandstones.

Case Study: Bracing Crumbling Dock

Published Year: 1960

  • An eight-year-old loading and mooring dock, 1600 feet long, at Sept Iles was showing distress. It had been constructed by driving sheet piling then placing a heavy rockfill as a base.

Case Study: Blocking Artesian Flows

Published Year: 1960

  • In Oregon's Deschutes River canyon, a 440-foot dam sits on Pelton basalt formed by lava flows. Springs emerged from lava contacts, necessitating closure beneath the dam. Deschutes sediments were exposed on the dam abutments, which made using cement grout

Case Study: Stabilizing Soil for Construction Tunnels

Published Year: 1960

  • In this project, two 12-foot diameter by 270-foot long tunnels were to be driven beneath thirteen sets of live railroad tracks on the property of the New York Central, New York, Susquehanna, and Western Railroads.

Case Study: Shutting Off Water During Tunneling

Published Year: 1960

  • A six- foot diameter tunnel, 139 feet long, had to be driven through a cinder-slag fill with voids estimates as high as 70 percent. The tunnel dropped 25 feet over its length and terminated in a cofferdam about 23 feet below river level.

Case Study: Sealing Sandstone to Permit Shaft Sinking

Published Year: 1960

  • In one of the deepest drilling operations in British coal mining history, plans called for the sinking of two 3,000-foot shafts, one to be used as a main coal-hoist shaft with skips, the other to house a conventional cage hoist.

Case Study: Sealing Leaks in a Dry Dock

Published Year: 1960

  • Fitzroy Dry Dock, the oldest in Australia, was constructed in the days of sailing ships. Time and water pressure had eroded some of the jointing material, and sea water was entering the dock in a number of places.

Case Study: Repairs to Leaking Earthen Dam

Published Year: 1960

  • Indian Kill Reservoir is a man- made lake (capacity 200 million gallons.) serving a portion of Sterling Forest, a community developed for scientific research, education, and suburban living.

Case Study: Increasing Oil Production

Published Year: 1960

  • Problem: A petroleum production water flood project was not responding well to flooding. An injection profile indicated that about half of the injected water was entering the zone between the two perforated intervals.

Case Study: Improving Oil Production in a Water Flood Cave

Published Year: 1960

  • Problem: Water was pumped down a well to displace petroleum from the oil-bearing formation into an oil producing well.

Case Study: Grouting River Beds for Dam Corewall Construction

Published Year: 1960

  • A high earth- fill dam was being constructed across the Grijalva River. After diversion of the river, seepage was still occurring through the riverbed sands.

Case Study: Grouting Jointed Rock in Dam Foundation

Published Year: 1960

  • Problem: Severe weathering along calcite veins, joints, and cracks, as well as the presence of three fault zones, have formed seepage channels which could endanger the performance of the dam.

Case Study: Grouting in Fissured Rock

Published Year: 1960

  • Pumping costs at Cedar Bay Mine were becoming excessive, as new drifts were opened and total seepage into the mine increased.
