Abstract:

Instrumentation was developed and used in the field to monitor the presence and flow of grout during remedial grouting of the Old River Low Sill Control Structure. Measurements were also made of uplift pressures by means of transducers installed in packers in drilled holes through the slab. This report presents information on the development and field use of instruments to detect the presence of grout, the rate of buildup under the base of the structure, and pressure increase under the slab due to grouting operations. All data were electronically recorded and were used extensively to regulate the grouting operation. Author
