REPORT FINDS SLURRY TRENCH WALL SYSTEM PRACTICAL, ECONOMICAL, AND VERSATILE
The slurry trench method of wall construction, used widely in Europe for a variety of foundation and retaining wall applications, is a practical, economical alternative to other ground support methods. It warrants further study in U.S.A. and should be included as an alternate in appropriate construction contracts, says a report on "The Design and Construction of Diaphragm Walls in Western Europe, 1979." The newly-published report describes the result of a study carried out by the International Road Federation for the Federal Highway Administration, U.S. Department of Transportation. The slurry trench method, also called the diaphragm wall method, consists of constructing a wall in a narrow fluid-filled trench. As the excavation proceeds, the trench is kept filled with a dense bentonite (clay) slurry which supports the sides of the trench until the slurry is replaced by cast-in-place concrete or precast concrete panels. The report identifies the principal advantages of slurry trench walls as: use of the wall as both temporary ground support and as the permanent wall; ease of construction in narrow confines; excellent barrier to groundwater flow, and a rigid support for open excavations to great depth; and in place off underpinning of adjacent structures. The slurry trench method was found to be an economical alternate for construction of a depressed section of highway where the cut section requires vertical retaining walls. (Author)
