PVC reducing wye
Eight of the tanks contain a single riser/vent pipe. In addition, four of these tank riser/vent pipes were only 0.07m in diameter. Therefore, a separate system was designed that incorporated the grout delivery piping and off-gas filter system for these tanks. The grout delivery system is similar to the double riser system except that the pipe diameter is only 0.04m. Also, the grout delivery tube is extended into the tank to mitigate grout/air exchange in the small diameter riser. A 0.07m carbon steel wye is located within the system. One branch contains the off-gas system, identical to the double riser system, and the other contains the connection to the grout delivery system. A pressure gauge is also installed on the single riser system. Solidification materials are added to an OST through a funnel
and PVC piping arrangement. The initial system consisted of a
plastic funnel, with a 0.06m neck, and 1-meter pieces of 0.05m
PVC that screwed together. The final piece of PVC, the piece that
protruded into the tank, could be configured to contain a straight
end, a 45-degree end, or a 90-degree end depending on the desired
projection of material throw. The pieces were screwed together
and lowered into the tank riser. Lastly, the funnel was added
and used to support the assembly on the tank riser during the
material addition.
