Equipment
This chapter examines the types and sizes of equipment required to drill grout holes, proportion and mix grout materials, and deliver and inject grout into the holes in an underground...
Uses and Limitations of Conventional Hydraulic Models in the Planning and Design of Storage Tunnels
The hydraulic design of storage tunnels requires special considerations relative to the design of conventional sewers. These issues include characterization and control of inflows, energy...
Two-in-One Tunnel
Engineers are converting the 2.6 mi (4.2 km) Anton Anderson Railroad Tunnel that connects the isolated town of Whittier, Alaska, to the rest of the state into a combination highway-railroad...
Fanfare (Available only in Special Structural Issue)
The owners of the Milwaukee Brewers baseball team decided in the late 1980s that their current home, the 50-year-old County Stadium, could no longer offer the facilities that attract crowds...
Structural Aerodynamics (Available only in
One of the most strikingly ambitious public buildings in France, county governmental headquarters in Marseille, achieves the status of world-class architecture largely through its structural...
Bare Bones Buildings
A new approach to fire engineering opens possibilities of designing buildings in which the structural skeleton is part of the architectural statement. Fire and corrosion requirements used...
New Way Out
An obsolete and hazardous ventilation/emergency-exit shaft on the banks of the Hudson River has been replaced with a deep, dual-shaft system that connects to a 100-year-old train tunnel...
Mine Support, Radiation and Ventilation Control with Spray-on Barriers
The use of spray-on liner agents to provide localized excavation support in place of traditional techniques such as shotcrete or bolts-and-screen has been the subject of extensive investigation....
Hong Kong's Wastewater Underground
Standard Hong Kong methods for siting the new $18 million Stanley Wastewater Treatment Plant in Hong Kong Island's South District were running into trouble. The rocky coastal...
Commissioning of High Level Liquid Waste Facilities
A programme of commissioning tests was carried out on the latest High Level Liquid Waste Evaporation and Storage Facilities constructed at BNF plc Sellafield, England. These tests set...
The Processing of Simulated High-Level Radioactive Waste Sludges Containing Nitrites and Mercury
The reaction of formic acid with simulated alkaline sludge containing mercury and nitrite was studied in an engineering-scale facility. Quantification of offgas production was performed,...
Emplacement Drift Temperature Reduction by Cooling Enhancement and Ventilation
The application of cooling enhancement in a short vertical container emplacement layout is analyzed. Two 25 m-long heat pipes upward oriented at 45 degrees are installed at each emplacement...
Continuing Effort to Eliminate Odors at Orange County's Wastewater Treatment Plants
The County Sanitation Districts of Orange County (CSDOC), California own and operate two wastewater treatment plants. Reclamation Plant No. 1, in Fountain Valley, treats approximately...
Ventilation and Construction Considerations for a High Level Nuclear Waste Repository
The storage of high level nuclear waste in an underground repository presents engineering problems in ventilation, construction methods and plan, and in proposed retrievability. Temperatures...
Vaporizing VOCs
The authors summarize the findings of a study for the Environmental Protection Agency on vapor extraction of volatile organic compounds from soils. The potential for ground water contamination...
Aeration of a Submerged Jet-Flow Gate
Submerged operation of a jet-flow gate requires special treatment of the area downstream from the gate to avoid cavitation damage. The Bureau of Reclamation studied operation of a submerged...
Radon Resistant New Construction Practices
This paper highlights the basic principles for building radon-resistant houses and it groups the construction techniques into four categories, i.e., the barrier approach, soil ventilation...
A Station With a View
The Port Authority TransHudson Corp. (PATH) is renovating and expanding Exchange Place station, the first stop in New Jersey across the Hudson River from lower Manhattan. To be completed...
The Great Highway Coverup
Public opinion has forced changes in highway design since the first ones were built 30 years ago. In the Seattle area, this environmental sensitivity led to federal court action and to...
Model Study to Locate Aerators in Tunnel Spillways
A model study to locate, in an optimum way, aerators in tunnel spillways is presented. A Froude half model, scale 1:30, was used. The flow geometry, the air discharge sucked by the aerators...
