Foundation Consolidation Technique with Single Direction Swing-jet Grorting

Abstract:

High Pressure swing-jet grouting is a new technique which is developed basing on high pressure directional grouting. Some parmeters and new suggestions of single directional grouting are proposed through investigation, research,laboratory and field tests.These parameters,gained from above tests were used inconsolidating the foundation of a rotay tan house in Datong Coal Mine ,the expected good result was reached.
