trated in Figure 3-48 by the use of a fire water monitor. After grouting,
clean-up operations are made easier if the machined surfaces of the base-
plate have been greased or covered with plastic, and sand sprinkled on
the slab in the path from the mixer prior to the pour. There will be grout
spills in the process of grouting, and they are easy to shovel up when
mixed with sand.
As the epoxy grout begins to harden, form a dome of grout over the
baseplate grout holes to prevent a low spot that might hold water (Figure
3-49). The grout extrusions at the baseplate vent holes can be removed at
this time or broken off flush with the baseplate when they have cured.
Wait 24 hours before removing the grout forms, and three days before
removing the jack screws. Clean the thread lubricant from the jack-screw
holes with a degreaser and fill the holes with epoxy or liquid rubber to
seal out moisture and oil. A small but important point that has not been
covered is the greasing and insertion of the coupling guard bolts into the
baseplate. Epoxy grout will use those tapped holes as air vent holes if not
plugged. It is very hard to drill and tap the holes after being filled with
grout.
