Construction and In-Situ Hydraulic Conductivity Evaluation of a Deep Soil-Cement-Bentonite Cutoff Wall
This paper presents a case study of a deep soil-cement-bentonite (SCB) slurry trench cutoff wall constructed outside of Smithland, KY in 2010. Installed to a
INSTALLATION OF A SOIL-BENTONITE CUTOFF WALL 4 THROUGH AN ABANDONED COAL MINE
The site is a 72,846 square meter (18-acre) abandoned strip mine located in Western Pennsylvania used for municipal and industrial waste disposal until the mid-1970’s.
Installation of a composite slurry wall to contain mine tailings
This paper describes a case study on the design, construction and performance of an underground barrier intended to contain copper mine leachates in central Arizona.
EVALUATION OF SUBSURFACE ENGINEERED BARRIERS AT WASTE SITES
Subsurface engineered barriers have been used to isolate hazardous wastes from contact, precipitation, surface water, and groundwater. The purpose of this report is to provide
INNOVATIVE SLURRY TRENCH METHODS FOR THE REHABILITATION OF SMALL DAMS
The rehabilitation of small dams often requires the reduction or control of groundwater seepage through or under earthen dams. The slurry trench method is well
Soil-Cement-Bentonite Slurry Walls
Soil-Cement-Bentonite (SCB) slurry walls have been used with increasing frequency in recent years to provide barriers to the lateral flow of groundwater in situations where
Soil-Bentonite Slurry Wall Specifications
Specifications for the construction of Soil-Bentonite slurry walls have been developing for over 30 years. In this paper, the elements of good specifications and recommended
Time-Dependent Strength Behavior of Soil-Bentonite Slurry Wall Backfill
Soil-bentonite (SB) slurry trench cutoff walls have been used for over 30 years as subsurface vertical barriers to control ground water flow and contaminant transport.
DESIGN AND CONSTRUCTION CONSIDERATIONS FOR THE USE OF SLURRY WALLS TO CONSTRUCT WATER RESERVOIRS IN THE DENVER FORMATION
Continued population growth combined with limited water resources in the Denver area has resulted in the conversion of a number of mined out gravel pits
