Effect of Shallow Trench Construction on Cast Iron Pipelines
This paper summarizes the results of three-dimensional finite element analyses to evaluate the strains and displacements sustained by 4, 6, and 8-in. (100, 150, and 200 mm)-diameter cast...

Successful Use of Trench Box in Sewer Line Construction
Faced with the problems of ever increasing construction costs, more and more methods are being employed in an attempt to keep expenses to a minimum without sacrificing the quality of construction...

Influence of Frost Action on the Load Exerted on Buried Pipe
When work was started on revising the Swedish code for concrete pipes at the end of the 70's, a research project was carried out to evaluate the risk of increased load due...

Exfiltration Trench Design as Part of a Stormwater Management Plan
The paper discusses a program structured to assist the design consultant or the agency reviewer by means of a menu driven format. A flood routing microcomputer program developed by the...

Coal Pile—Slurry Wall Design

Vibration Isolation of Machine Foundations

Pipe Laying Comes Out of the Trenches
Recent developments have shown that trenchless construction offers an effective and economically attractive alternative to conventional excavation. These findings are especially important...

Slurry Trenches for Containing Hazardous Wastes
Slurry trench technology has not advanced much during the past 10 years due to a lack in research and development, the excerbated litigious climate in the environmental protection field,...

Constructing a Trench Drain at a Superfund Site

Innovations Cut Costs of a Power Plant's Water System
A two-unit (660 MW each) coal-fired power plant in St. Clair, MI, requires 660,000 gallons of water for condenser cooling. A once through cooling system from the St. Clair River (one mile...

Trenching and Excavation Safety

Current USA Practices: Slurry Wall Specifications
The critical design criteria and the resulting specifications for slurry trench diaphragm walls and cutoff walls are discussed. To establish diaphragm and cutoff slurry wall design criteria...

Diaphragm Wall Behavior - A Case Study

A Low-Level Waste Shallow Burial Assessment Code

Composite Pipe - Deflection Response

Trenching of Digested Sludge
Effects of trenching digested sludge were evaluated for 4 yr. Digested sludge buried in trenches that were 2 ft (0.6m) wide by 2 ft (0.6m) deep and 2 ft (0.6m) apart was sampled along...

Soil-Bentonite Slurry Trench Cutoffs
Soil-bentonite cutoff walls constructed by slurry trench methods have been employed for about 3 decades. Soil-bentonite cutoff walls are constructed by excavating a continuous narrow trench...

Applications of Slurry Walls in Civil Engineering
Slurry wall (also called diaphragm wall) construction developed in the last three decades is a relatively new technique in civil engineering. It has been applied to a variety of projects...

Earth-Filled Slurry Walls Provide Economical Seepage Control
Slurry trench cut-off walls are often used for seepage control after structures requiring excavation are completed, but at a construction site on the Tennessee-Tombigbee Waterway project...

Entrenchment of Sewage Sludge—a Disposal-Use Alternative
Entrenchment of sewage sludge is an alternative for the disposal and use of sewage sludge. Its advantages include high disposal rate, little odor problem, and no surface runoff. Two methods...
