Pressure grouting is an essential
construction procedure that is practiced by contractors and engineers
around the world. Used since the 19th century, grouting reduces the
amount of leakage through rock for dam foundations and underground
works. It also strengthens soils to provide a stable foundation to
support the weight of surface structures, such as buildings, bridges,
and storage tanks. In addition, it is frequently used to repair
deteriorated concrete and to produce concrete underwater.
This
manual introduces various types of equipment employed in pressure
grouting applications performed in geotechnical works and examines the
operating principles and maintenance issues relative to each equipment
type.
The term pressure grouting encompasses a wide
variety of applications and operations, including dam foundation
grouting, soil stabilization and permeation, consolidation and
compaction grouting (except low-mobility), water cutoff and structural
stabilization in rock tunnels, deep foundations via drilled piers,
underwater concrete, structural concrete repairs, raising of settled
slabs and structures, rock and soil anchors, and machine foundations and
bases. The applications for pressure grouting operations are almost
limitless, as the equipment can be employed anywhere fluid grout can be
used.
Primarily intended for machine operators and maintenance
mechanics, this manual will also prove useful to specification writers,
engineers, contractors, purchasing managers, and others who have a
responsibility to specify, acquire, operate, or maintain pressure
grouting equipment. Topics covered include mixers, agitators, pumps,
delivery systems and accessories, but not electronic monitoring and
other ancillary equipment.
