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: Controlling Seepage During Construction of Underground Missile Bases

Published Year: 1960

  • Problem: With construction still in progress, numerous leaks appeared at the joints and bolt holes of corrugated steel-pipe tunnels connecting missile silos to control centers. Welding and sealing compounds failed to stop seepage.

Case Study: Controlling Seepage During Shaft Sinking

Published Year: 1960

  • In order to reach newly discovered lead deposits, St. Joseph Leak Company had to sink large diameter deep shafts through permeable Lamotte Sandstone carrying ground water at high pressures.

Case Study: Cutting Water Flow in Colliery Drift

Published Year: 1960

  • Problem: In driving two drifts for this new project, several badly fissured water-bearing rock zones were intercepted. Upon completion, water at the rate of several thousand gallons per hour was entering the drifts from a subterranean water table.

Case Study: Grouting Foundation for Dam Construction

Published Year: 1960

  • A 300-foot rockfill dam with a central impervious core and a crest length of 870 feet was being built on a generally sound granite foundation, except on the upper right abutment where the rock was completely weathered to an in situ soil.

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.

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 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: 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: 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: 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: 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: 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: 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: 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.
