The Basics of Geotechnical Construction Drilling – Part 1
Mar 28, 2006· The specialty geotechnical construction processes of grouting, anchoring, micropiling, soil nailing and ground freezing all require the drilling of holes through overburden and/or rock. Such holes typically are 3 inches to 12 inches in diameter and are rarely more than 200 feet deep.Author: Donald Bruce
Grouting techniques for the unfavorable geological
Grouting is critically important in tunnel engineering. The compaction grouting mode or hydro-fracture grouting mode can be used depending on the local geological conditions of the given project (Soga et al., 2004).To date, the majority of grouting applications have adopted the soil fracture technique (Essler et al., 2000).However, as grouting is a complex process, both permeation grouting and …Cited by: 18
