Microtunneling and HDD Performance in Jet Grouted Soil

Publication: Grouting and Ground Treatment
Abstract
Jet grouting has become a common method of ground improvement for microtunneling (MT) and horizontal directional drilling (HDD) in difficult ground conditions. Both MT and HDD performance is evaluated for two recent major Honolulu projects with complex geologic conditions where jet grouting served both temporary and permanent roles. While similar concepts have been applied with jet grouting at other microtunnel or tunnel sites, quantitative evaluation of improved MT or HDD performance appears lacking in literature. Effects from variations in jet grout column designs are presented based on field observations and collected data. Performance evaluation criteria is discussed for grouting and trenchless projects, illustrating benefits of combined uses.
