Grouting of Scoured Foundation, Old River Low Sill Structure, Louisiana.

摘要

In the emergency grouting operations at the Old River Low Sill Structure, Louisiana, in late 1973 and early 1974, the Concrete Laboratory of the U.S. Army Engineer Waterways Experiment Station was responsible for (a) development of a series of grout mixtures for placement in scoured areas, (b) supervision of mixing and placement of the grout mixtures, (c) development of instrumentation for monitoring uplift pressure and grout levels and locations beneath the structure, (d) the actual monitoring of uplift pressure and grout levels during grouting operations, and (e) determining the physical properties of field-placed grout. It is believed, after many check borings, that the physical properties of the field-placed grout closely match the design criteria, and the scoured areas have been successfully replaced. (Author)
