A pressure gauge, pressure transducer, and flow meter are located at the
discharge of the grout pump. The pressure and grout flow are recorded by the
data acquisition system. A high-pressure, automatic shut-down feature stops
the pump if the grout discharge pressure exceeds the preprogrammed maximum
pressure of 125 psi.
2.5 PIPING
The grout pump discharges into a 3/4-in. schedule-40, carbon steel pipe
that leads to a series of three-way valves. These valves can direct the grout
slurry either to the gradient mold, the lift mold, or a dumpster. The total
length of pipe when plumbed to the dumpster was 100.5 ft, when plumbed to the
lift mold was 119.25 ft, and when plumbed to the gradient mold was 135.5 ft.
The dumpster was used to receive flush water and grout not being used in the
testing. A thermocouple measured the grout temperature just prior to the
three-way valves.
2.6 GRADIENT MOLD
The gradient mold was constructed from an 8-ft dia'x 7.5-ft high, carbon
steel tank. This tank was placed on a structural support, and its
circumference was surrounded by platecoils. The top and bottom were insulated
to minimize the heat loss through those surfaces. Water was continuously
circulated through the plate coils with a centrifugal pump. A heated 55-gal
drum was part of the circulation loop and was used to help maintain a target
temperature of 38oC in the plate coils. The exterior of the plate coils was
insulated to reduce the heating requirements and improve temperature
uniformity. The stand and plate coils were designed to allow disassembly and
reuse for subsequent grout pilot-scale tests. At the completion of the tests,
the grout will be disposed of in the carbon steel tank. Figure 2.6 shows the
gradient mold in its test location west of the high bay area of 324 Building.
The gradient mold was equipped with a 1-ft diameter, 27.5-ft long,
polyvinyl chloride (PVC) pipe through which the grout fell -35 ft after
discharging from the grout pipe. This simulates the maximum drop that the
grout will see in the full-scale vault.2.3
