Equipmentby Raymond W. Henn,
Part of: Practical Guide to Grouting of Underground Structures
Abstract: This chapter examines the types and sizes of equipment required to drill grout holes, proportion and mix grout materials, and deliver and inject grout into the holes in an underground work environment. The most common power sources for underground grouting equipment are air, electric, and electric-hydraulic. Diesel-powered equipment is also common and, when used, requires the installation of a scrubber on the equipment's exhaust system. The use of diesel equipment may also increase the underground ventilation requirements beyond what is already in place, thereby requiring additional primary or ancillary ventilation capacity to be installed. Gasoline-powered equipment is not allowed by law to be used underground.
